[0018]
FIG. 1 is a perspective view showing Example 1 of a mobile phone according to an embodiment
of the present invention. In FIG. 1, the mobile phone 1 comprises an upper portion 7 having a
display portion 5 and the like, an operation portion 9 such as a ten key, and a lower portion 11
having a microphone 23 or other microphone , The upper part 7 is configured to be foldable on
the lower part 11 by the hinge part 3. The upper part 7 is provided with a receiver 13 such as an
earphone for transmitting voice to the operator's ear, and constitutes a telephone function
together with the transmitter 23 of the lower part 11. Further, in the upper part 7, when the
mobile phone 1 is used as a videophone, the face of the operator looking at the display unit 5 can
be photographed, and the inner camera 17 used also for taking a picture is arranged It is done.
Furthermore, in the upper part 7, infrared reflected light from the pair of infrared light emitting
parts 19 and 20 and the ear that constitute a proximity sensor for detecting that the mobile
phone 1 is in contact with the ear for a call A common infrared light proximity sensor 21 for
receiving light is provided. Although not shown in FIG. 1, a rear surface camera is provided on
the rear surface of the upper portion 7 so that a subject to be monitored by the display unit 5
can be photographed on the rear surface side of the mobile phone 1.

[0019]
The upper portion 7 is further provided with a vibrating portion 24 for the right ear and a
vibrating portion 26 for the left ear, which are made of a piezoelectric bimorph element or the
like for contacting the tragus, at an upper (inner side) corner. Although the right ear vibration
unit 24 and the left ear vibration unit 26 are configured not to protrude from the outer wall of
the mobile phone so as not to damage the design, they are effectively provided in the tragus by
being provided at the corners of the outer wall of the mobile phone. Contact. As a result, in
addition to the reception by voice from the receiver 13, reception can be performed by bone
conduction from the cartilage of the tragus. In addition, as disclosed in the above-mentioned
Patent Document 2, the tragus is pressed while being able to obtain the largest auditory
sensation in the configuration of the ear cartilage such as the ear mastoid, the posterior cartilage
surface of the external ear opening, the tragus and the chaff It is known that the rise in bass
when pressure is increased is greater than at other positions. Since this knowledge is described in
detail in Patent Document 2, it can be referred to.
[0020]
When the mobile phone 1 is put on the right ear, it turns slightly clockwise in FIG. 1 and falls to
the right in FIG. Then, by providing the right-ear vibration unit 24 at the inclined lower side
corner of such a mobile-phone ear-side upper end, the right-ear vibration unit 24 naturally
becomes a right ear without causing the vibration unit to protrude from the mobile phone outer
wall. It can be in contact with the beads. This state is a posture close to a normal call state, and
there is no sense of incongruity between the caller and the person on the side. Since the
receiving unit 13 is in the vicinity of the right ear vibration unit 24, both voice information via
tragus cartilage and voice information via the ear canal are transmitted to the ear. At this time,
since the same voice information is transmitted by different sounding pairs and routes, phase
adjustment between the two is performed so as not to cancel each other.
[0021]
On the other hand, when the mobile phone 1 is placed on the left ear, the mobile phone 1 slightly
rotates in the counterclockwise direction in FIG. Then, similarly to the case of the right ear, the
left ear vibration unit 26 is provided at the inclined lower side corner of the mobile phone ear
10-05-2019

side upper end, and the left ear vibration unit 26 naturally becomes the tragus of the left ear. Can
be in contact with Since this state is a posture close to a normal talking state, and since the
receiving unit 13 is in the vicinity of the left ear vibration unit 26 and both voice information via
trabecular cartilage and voice information via the ear canal are transmitted to the ear, The phase
adjustment between the two is performed as in the case of the right ear.
[0022]
Since the pair of infrared light emitting portions 19 and 20 in the proximity sensor emit light
alternately in time division, the common infrared light proximity sensor 21 reflects the reflected
light by infrared light from any of the light emitting portions. It is possible to discriminate
whether light is received, and it is possible to judge which of the right ear vibration unit 24 and
the left ear vibration unit 26 is in contact with the tragus. By this, it can be determined which ear
the mobile phone is being used, and it is possible to vibrate the vibrating portion of the one in
contact with the tragus to turn off the other. However, since there is variation in how to put the
ear of the mobile phone 1 on the ear and the difference in the shape of the ear, in Example 1, the
acceleration sensor is built in as described later, and the gravity acceleration detected by this
acceleration sensor Thus, it is configured to detect to which side the mobile phone 1 is inclined,
and to vibrate the vibrating portion at the lower side angle of the inclination so as to turn off the
other. The use of the right ear and the use of the left ear described above will be described again
with reference to the respective specification states.
[0023]
Environmental noise that is further disposed on the upper part 7 on the outside (back side not
hitting the ear) so as to pick up environmental noise, and means for preventing conduction of the
vibration for the right ear and the left ear. A microphone 38 is provided. The environmental noise
microphone 38 further picks up the sound produced from the operator's mouth. Environmental
noise picked up by the environmental noise microphone 38 and the operator's own voice are
reversed in phase, mixed with the right ear vibration unit 24 and the left ear vibration unit 26,
and the environment included in the voice information via the receiver unit 13 Cancel the noise
and the operator's own voice to make it easy to hear the other party's voice information. Details
of this function will be described later.

FIG. 2 is a side view of the mobile phone 1 showing the functions of the right ear vibrating unit
24 and the left ear vibrating unit 26. FIG. 2 (A) shows the right hand holding the mobile phone 1
in the right hand Show the status. On the other hand, FIG. 2 (B) shows a state in which the mobile
phone 1 is held in the left hand and applied to the left ear 30. 2 (A) is a view from the right side
of the face, and FIG. 2 (B) is a view from the left side of the face, so the mobile phone 1 is on the
back side (the back side of FIG. 1). Is visible. In order to illustrate the relationship between the
mobile phone 1 and the right ear 28 and the left ear 30, the mobile phone 1 is indicated by an
alternate long and short dash line.
[0025]
As shown in FIG. 2 (A), when the mobile phone 1 is put on the right ear, it is slightly inclined in
the counterclockwise direction (the relationship between FIG. 1 and front and back) in FIG. . And
since the ear vibration unit 24 is provided at such a slanted lower side corner of the upper end
on the side of the mobile phone, it can be brought into contact with the tragus 32 of the right ear
naturally. As described above, this state is a posture close to that of a normal call state, and there
is no sense of incongruity either for the caller or for the side. On the other hand, as shown in FIG.
2 (B), when the mobile phone 1 is put on the left ear, it is slightly inclined clockwise in FIG. 2
(relationship between FIG. 1 and front and back) and in FIG. Become. Then, since the ear
vibration unit 26 is provided at the inclined lower side angle of the upper end on the side of the
mobile phone, it can be brought into contact with the tragus 34 of the left ear naturally. Also in
this state, as in the case of the right ear, the posture is similar to that of the normal
communication state, and there is no sense of incongruity to either the caller or the side.
[0026]
FIG. 3 is a block diagram of the first embodiment. The same reference numerals as in FIG. 1
denote the same parts, and a description thereof will be omitted unless necessary. The mobile
phone 1 is controlled by a control unit 39 operating according to a program stored in the storage
unit 37. The storage unit 37 can also temporarily store data necessary for control of the control
unit 39, and can store various measurement data and images. The display of the display unit 5 is
performed based on the display data held by the display driver 41 based on the control of the
control unit 39. The display unit 5 has a display backlight 43, and a control 39 adjusts the
brightness based on the surrounding brightness.

[0027]
The telephone function unit 45 including the receiver 13 and the transmitter 23 can be
connected to a wireless telephone line by the telephone communication unit 47 under the
control of the control unit 39. Under the control of the control unit 39, the speaker 51 performs
a ringing tone and various types of guidance, and outputs the other party's voice at the time of a
videophone call. The audio output of the speaker 51 is not output from the right ear cartilage
transmission vibration unit 24 and the left ear cartilage transmission vibration unit 26. This is
because in the case of videophone, there is no possibility that the cartilage conduction vibration
unit may hit the ear. The image processing unit 53 is also controlled by the control unit 39 to
process an image captured by the videophone inner camera 17 and the rear main camera 55,
and inputs an image of the processing result to the storage unit 37.
[0028]
As described above, the pair of infrared light emitting units 19 and 20 in the proximity sensor
emit light alternately in time division based on the control of the control unit 39. Therefore, the
infrared reflected light input to the control unit 39 by the common infrared light proximity
sensor 21 can be identified as the reflected light by the infrared light from any light emitting
unit. When the reflected light is detected from both of the infrared light emitting parts 19 and
20, the control part 39 compares them with each other, and either the right ear vibrating part 24
or the left ear vibrating part 26 is in contact with the tragus To determine the Furthermore, the
acceleration sensor 49 detects the direction of the detected gravitational acceleration. Based on
the detection signal, the control unit 39 determines which of the states shown in FIG. 2 (A) and
FIG. 2 (B) the mobile phone 1 is inclined, and as described in FIG. A certain vibration part is
vibrated and the other is turned off.
[0029]
The mobile phone 1 further has a phase adjustment mixer unit 36 for performing phase
adjustment on the audio information from the control unit 39 and transmitting the phase
adjustment to the right ear vibration unit 24 and the left ear vibration unit 26. More specifically,
the phase adjustment unit 36 generates voice information generated from the receiving unit 13
and transmitted from the ear canal via the tympanic membrane and generated from the right ear
vibration unit 24 or the left ear vibration unit 26 via tragus cartilage The phase adjustment is
performed on the voice information from the control unit 39 on the basis of the voice
10-05-2019
11
information transmitted from the control unit 39 to the receiver unit 13 so that the same voice
information transmitted in the above does not cancel each other, and the right ear vibration unit
24 and the vibration unit 26 for the left ear. Since this phase adjustment is relative adjustment
between the earpiece 13 and the right ear vibration unit 24 and the left ear vibration unit 26, the
control unit 39 transmits the phase adjustment to the right ear vibration unit 24 and the left ear
vibration unit 26. The phase of the audio information transmitted from the controller 39 to the
receiver 13 may be adjusted based on the transmitted audio information. In this case, the audio
information to the speaker 51 is also adjusted in the same phase as the audio information to the
receiver 13.
[0030]
In addition, the phase adjustment mixer unit 36 prevents the voice information from the
receiving unit 13 as described above and the same voice information from the right ear vibration
unit 24 or the left ear vibration unit 26 from canceling each other. And the second function in
cooperation with the environmental noise microphone 38. In this second function, the
environmental noise picked up by the environmental noise microphone 38 and the voice of the
operator are phase-reversed by the phase adjustment mixer unit 36, and then the voice
information of the right ear vibration unit 24 or the left ear vibration unit 26. Thus, the
environmental noise and the voice of the operator himself contained in the voice information via
the receiver 13 are canceled to make it easy to hear the voice information of the other party. At
this time, the environmental noise and the voice of the operator are effectively effective
regardless of the difference in the transmission route of the voice information from the receiver
13 and the voice information from the right ear vibration unit 24 or the left ear vibration unit 26.
Mixing is performed in consideration of the phase adjustment based on the first function so as to
be canceled.
[0031]
FIG. 4 is a flowchart of the operation of the control unit 39 in the first embodiment of FIG. The
flow in FIG. 4 mainly illustrates the functions related to the functions of the right ear vibration
unit 24 and the left ear vibration unit 26, so that the operation is extracted and illustrated, and a
general mobile phone The operation of the control unit 39 not shown in the flow of FIG. The flow
in FIG. 4 starts with the main power on by the operation unit 9 of the mobile phone 1, performs
initial start-up and function check of each unit in step S 2, and starts screen display on the
display unit 5. Next, in step S4, the functions of the right ear vibration unit 24 and the left ear
vibration unit 26 are turned off, and the process proceeds to step S6. In step S6, it is checked
10-05-2019
12
whether there is an operation (hereinafter collectively referred to as "non-call operation") that
does not use radio waves such as mail operation, Internet operation, other various settings and
downloaded games. Then, if these operations are performed, the process proceeds to step S8 to
execute non-call processing, and the process proceeds to step S10. In the non-call operation, the
function of the receiver 13, the right ear vibration unit 24 and the left ear vibration unit 26 in
the upper part 7 of the mobile phone 1 is not assumed to be performed. On the other hand, when
a non-call operation is not detected in step S6, the process directly proceeds to step S10.
[0032]
In step S10, it is checked whether a call by mobile radio waves is being received. If the incoming
call is not in progress, the process proceeds to step S12, and it is checked whether the response
from the other party to the call origination from the mobile phone 1 is correct. And if a response
is detected, it will progress to step S14. On the other hand, when it is detected in step S10 that a
call by mobile radio waves is being received, the process proceeds to step S16 to determine
whether the mobile phone is open, that is, the upper part 7 is folded over the lower part 11
Check whether it is in the opened state as shown in FIG. Then, if it is not detected that the mobile
phone is open, the process returns to step S10, and thereafter, steps S10 and S16 are repeated to
wait for the mobile phone to be opened. If the incoming call ends with this repetition without the
mobile phone being opened, the flow moves from step S10 to step S12. On the other hand, when
it is detected in step S16 that the mobile phone is open, the process proceeds to step S14. In step
S14, the transmitting unit 23 and the receiving unit 13 are turned on, and the process proceeds
to step S18. In step S18, it is checked whether the call is a videophone call, and if it is not a
videophone call, the process goes to step S20 to check whether the call is disconnected at this
time and goes to step S22 if the call is not disconnected.
[0033]
In step S22, it is checked whether the infrared light proximity sensor 21 detects contact of the
ear. If contact is detected, the process proceeds to step S24. On the other hand, when the
infrared light proximity sensor 21 does not detect the ear contact in step S22, the process
returns to step S14, and steps S14 and steps S18 to S22 are repeated to wait for the proximity
sensor detection in step S22. In step S24, based on the detection signal of the acceleration sensor
49, it is checked whether or not the inclination of the right ear call state as shown in FIG. And if it
corresponds, it will progress to step S26, will turn on the cartilage conduction vibration part 24
for right ears, and will transfer to step S28. On the other hand, if it is not possible to detect that
the right ear call state tilt has occurred in step S24, the detection signal of the acceleration

sensor 49 detects the left ear call state tilt as shown in FIG. 2 (B). In step S30, the left ear
cartilage conduction vibration unit 26 is turned on, and the process proceeds to step S28.
[0034]
In the description of the flow in FIG. 4 above, the process proceeds to step S24 regardless of
whether the infrared reflected light detected by the infrared light proximity sensor 21 is from the
infrared light emitting unit 19 or 20, and in step S24 the acceleration sensor It has been
described that it is detected whether the right ear call state tilt is performed by the 49 signals.
However, since it is possible to detect whether the right ear call state tilt is also achieved by the
infrared light proximity sensor 21, in place of the signal of the acceleration sensor 49 in step S
24, the infrared light at the light emission timing of the infrared light emitting unit 19 If the
output of the proximity sensor 21 is larger than that at the light emission timing of the infrared
light emitting unit 20, it may be determined that the right ear call state tilt. Further, in step S24,
it is determined whether the right ear call state inclination is integrated by combining the signal
of the acceleration sensor and the output comparison result of the infrared light proximity sensor
21 at the light emission timing of the infrared light emitting portions 19 and 20. It may be
configured to
[0035]
In step S28, it is checked whether or not the call state is disconnected. If the call is not
disconnected, the process returns to step S24, and steps S24 to S30 are repeated until a call
disconnection is detected in step S28. This corresponds to the change of the cellular phone
between the right ear call state and the left ear call state during the call. On the other hand, when
a call disconnection is detected in step S28, the process proceeds to step S32, and the right ear
cartilage conduction vibration unit 24 or the left ear cartilage conduction vibration unit 26 and
the reception unit 13 and the transmission unit 23 are turned off. Then, the process proceeds to
step S34. On the other hand, when the call origination response is not detected in step S12, the
process immediately proceeds to step S34. When it is detected in step S18 that the telephone is a
videophone call, the process proceeds to the videophone processing in step S36. In the
videophone process, an image of the user's own face by the videophone inner camera 17, an
output of the other party's voice by the speaker 51, a sensitivity switching of the transmitter 23,
a display of the other party's face on the display 5, etc. are performed. When such videophone
processing is completed, the process proceeds to step S38, the speaker 51, the receiver 13, and
the transmitter 23 are turned off, and the process proceeds to step S34. Also, when a call
disconnection is detected in step S20, the process proceeds to step S38, but at this time, since the
10-05-2019
14
speaker 51 is not originally turned on, the reception unit 13 and the transmission unit 23 are
turned off, and the process proceeds to step S34.
[0036]
In step S34, the presence or absence of the main power off operation is checked, and if there is
an off operation, the flow is ended. On the other hand, when the main power off operation is not
detected in step S34, the flow returns to step S6, and steps S6 to S38 are repeated. As described
above, the right ear cartilage conduction vibration unit 24 or the left ear cartilage conduction
vibration unit 26 is in the call state even when the mobile phone 1 is not in the call state when
the mobile phone 1 is not opened. It does not turn on in the case of a videophone call, and also in
the normal call state, when the mobile phone 1 is not in the ear. However, when the right ear
cartilage conduction vibration unit 24 or the left ear cartilage conduction vibration unit 26 is
once turned on, the on / off switching with the right ear cartilage conduction vibration unit 24 or
the left ear cartilage conduction vibration unit 26 is performed. This is never turned off unless a
dropped call is detected.
[0037]
FIG. 5 is a perspective view showing Example 2 of the mobile phone according to the
embodiment of the present invention. Also in the second embodiment, since there are many
points in common with the structure, the corresponding parts are assigned the same reference
numerals as in the first embodiment, and the description will be omitted. The mobile phone 101
according to the second embodiment is not a folding method in which the upper and lower parts
are separated but an integral type without a movable part. Therefore, "upper part" in this case
does not mean the separated upper part, but means the upper part of the integral structure.
[0038]
In the first embodiment, when the mobile phone 1 is folded, the right ear cartilage conduction
vibration unit 24 and the left ear cartilage conduction vibration unit 26 are sandwiched between
the upper portion 7 and the lower portion 11 and stored. In contrast, in the second embodiment,
the right ear cartilage conduction vibration unit 24 and the left ear cartilage conduction vibration
unit 26 are always exposed to the outer wall of the mobile phone 101. Also in the second
embodiment, the internal structure of FIG. 3 and the flowchart of FIG. 4 can basically be diverted.
10-05-2019
15
However, relating to the difference in the above structure, step S16 of the flowchart of FIG. 4 is
omitted, and when it is confirmed in step S10 that a call is being received, the process directly
proceeds to step S14.
[0039]
FIG. 6 is a perspective view showing Example 3 of the mobile phone according to the
embodiment of the present invention. Also in the third embodiment, there are many points in
common with the structure, so the corresponding parts are assigned the same reference
numerals as in the first embodiment, and the description will be omitted. The mobile phone 201
according to the third embodiment has a structure in which the upper portion 107 can slide
relative to the lower portion 111. In the structure of the third embodiment, when the upper
portion 107 is overlapped with the lower portion 111, there is no vertical relation, but the
“upper” in the third embodiment means a portion coming up when the mobile phone 201 is
stretched. Do.
[0040]
In the third embodiment, when the upper portion 107 is extended to expose the operation unit 9
as shown in FIG. 6, full function is available, and the upper portion 107 is overlapped with the
lower portion 111 so that the operation unit 9 is hidden. However, basic functions such as
incoming call response and calls are available. In the third embodiment, the cartilage conduction
vibration unit 24 for the right ear and the cartilage conduction vibration unit 26 for the left ear
both in the state in which the portable telephone 201 is extended as shown in FIG. It is always
exposed to the outer wall of the mobile phone 201. Also in the third embodiment, the internal
structure of FIG. 3 and the flowchart of FIG. 4 can basically be diverted. However, as described
above, in the third embodiment, since the call is possible even in the state where the upper part
107 is overlapped with the lower part 111, step S16 of the flowchart of FIG. 4 is omitted as in
the second embodiment. If it is confirmed that an incoming call is in progress, the process
proceeds directly to step S14.
[0041]
The implementation of the above-mentioned various features of the present invention is not
limited to the above-described embodiment, and can be implemented in other embodiments. For
10-05-2019
16
example, in the above embodiment, the right ear cartilage conduction vibration unit 24 and the
left ear cartilage conduction vibration unit 26 are provided to cope with both the right ear use
and the left ear use due to changing hands or changing the user. However, when it is assumed
that only the right ear or the left ear is used for cartilage conduction, the cartilage conduction
vibration portion may be one.
[0042]
The right ear cartilage conduction vibration unit 24 and the left ear cartilage conduction
vibration unit 26 are originally provided on the premise that they abut on the tragus of the right
ear and the left ear, respectively. As shown, since cartilage conduction is also possible in other
ear cartilage configurations than the tragus, such as the ear mastoid and the posterior ear
cartilage surface, both the cartilage conduction vibration unit 24 for the right ear and the
cartilage conduction vibration unit 26 for the left ear For example, when using the right ear,
appropriate portions of the right ear cartilage may be simultaneously pressed and used. In this
sense, the two cartilage conduction vibration units 24 and 26 are not necessarily limited to those
for the right ear and the left ear. In this case, instead of turning on only one of the two cartilage
conduction vibration units 24 and 26 as in the embodiment, both are turned on simultaneously.
[0043]
Furthermore, in the above embodiment, the receiving part 13 and the cartilage conduction
vibration part 24 for the right ear or the cartilage conduction vibration part 26 for the left ear
are simultaneously turned on, but for the cartilage conduction vibration part 24 for the right ear
or the left ear When the cartilage conduction vibration unit 26 is turned on, the reception unit 13
may be turned off. In this case, phase adjustment of audio information is unnecessary.
[0044]
FIG. 7 is a perspective view showing Example 4 of the mobile phone according to the
embodiment of the present invention. Also in the fourth embodiment, since there are many
points in common with the structure, the corresponding parts are assigned the same reference
numerals as in the first embodiment, and the description will be omitted. The mobile phone 301
according to the fourth embodiment is not a folding method in which the upper part and the
lower part are separated in the same manner as the second embodiment, but is an integral type
10-05-2019
17
without a movable part. Moreover, it is comprised as what is called a smart phone which has the
big screen 205 provided with GUI (graphical user interface) function. Also in Example 4, the
"upper part" does not mean the separated upper part, but means the upper part of the integral
structure. In the fourth embodiment, the operation unit 209 such as a ten key is displayed on the
large screen 205, and the GUI operation is performed according to the touch or slide of the
finger on the large screen 205.
[0045]
The cartilage conduction vibration function in the fourth embodiment is borne by a cartilage
conduction vibration unit having a cartilage conduction vibration source 225 composed of a
piezoelectric bimorph element or the like and a vibration conductor 227. The cartilage
conduction vibration source 225 is disposed in contact with the lower portion of the vibration
conductor 227 and transmits the vibration to the vibration conductor 227. The cartilage
conduction vibration source 225 is configured to project from the outer wall of the mobile phone
(front in FIG. 7) in the same manner as in the first to third embodiments so as not to damage the
design. Transmitted laterally, causing both ends 224 and 226 to vibrate. Since both ends 224
and 226 of the vibration conductor 227 are located at the inner corner of the upper part 7 of the
mobile phone 301 in contact with the tragus, the ear is effectively eared without protruding from
the outer wall of the mobile phone as in the first to third embodiments. Contact the beads. Thus,
the right end portion 224 and the left end portion 226 of the vibration conductor 227
respectively constitute the right ear vibration unit 24 and the left ear vibration unit 26 described
in the first embodiment. Since the vibration conductor 227 vibrates not only at the right end 224
and the left end 226 but in the whole, in the fourth embodiment, even if the inner upper end side
of the mobile phone 301 is brought into contact with the ear cartilage Voice information can be
transmitted. Such a configuration of the cartilage conduction vibration unit allows the vibration
of the cartilage conduction vibration source 225 to be guided to a desired position by the
vibration conductor 227 and there is no need to arrange the cartilage conduction vibration
source 225 itself on the outer wall of the mobile phone 301. It is useful for mounting the
cartilage conduction vibration unit in a mobile phone which can be laid out freely and has ample
space.
[0046]
In the fourth embodiment, two more functions are added. However, these functions are not
specific to the fourth embodiment, and are also applicable to the first to third embodiments. One
of the additional functions is to prevent a malfunction of the cartilage transmission vibration unit.
10-05-2019
18
In any of the first to fourth embodiments, the infrared light emitting units 19 and 20 and the
infrared light proximity sensor 21 detect that the mobile phone is in contact with the ear. When
the sensor is placed on a desk or the like with the inner side down, there is detection of the
proximity sensor, so it may be mistaken that the cellular phone is touched by the ear, and the
process may proceed from step S22 to step S24 in the flow of FIG. And since it does not
correspond to the right ear speech state inclination detected in step S24, the flow proceeds to
step S30, and there is a possibility that the left ear cartilage conduction vibration unit is
erroneously turned on. Since the vibrational energy of the cartilage conduction vibration unit is
relatively large, such malfunction may cause vibration noise with the desk. In the fourth
embodiment, in order to prevent this, the horizontal stationary state is detected by the
acceleration sensor 49, and if applicable, the vibration of the cartilage conduction vibration
source 225 is prohibited. Details of this point will be described later.
[0047]
Next, the second additional function in the fourth embodiment will be described. In each
embodiment of the present invention, the right ear vibration unit 24 or the left ear vibration unit
26 (in the fourth embodiment, the right end 224 or the left end 226 of the vibration conductor
227) is used as a tragus of the right ear or the left ear. By making contact, the voice information
is transmitted, but by increasing the contact pressure and closing the ear hole with the tragus,
the earplug bone conduction effect is produced, and the voice information can be transmitted by
louder sound. Furthermore, since environmental noise is blocked by closing the earhole with a
tragus, use in such a state realizes a unique reception situation that reduces unnecessary
environmental noise and increases necessary voice information, for example, a station. It is
suitable for calls under noise. When the earplug bone conduction effect is produced, the voice by
the bone conduction from the vocal cords is increased, and the sense of balance between the left
and right sense of hearing is disturbed. In the fourth embodiment, the phase of the information
of the user's own voice picked up from the transmitter 23 is reversed and transmitted to the
vibration conductor 228 in order to alleviate such a sense of incongruity in the generation of the
earplug bone conduction effect. , Configured to cancel their own voice. The details of this point
will also be described later.
[0048]
FIG. 8 is a block diagram of the fourth embodiment, and the same reference numerals as in FIG. 7
denote the same parts. Further, since there are many parts in common with the first to third
embodiments, the corresponding parts are assigned the same reference numerals as those of the
10-05-2019
19
respective parts. The description of the same or common parts will be omitted unless necessary.
In the fourth embodiment, the telephone function unit 45 is illustrated in some detail, but the
configuration is the same as in the first to third embodiments. Specifically, the reception
processing unit 212 and the earphone 213 in FIG. 8 correspond to the reception unit 13 in FIG.
3, and the transmission processing unit 222 and the microphone 223 in FIG. 8 correspond to the
transmission unit 23 in FIG. On the other hand, the cartilage conduction vibration source 225
and the vibration conductor 227 in FIG. 7 are collectively illustrated as a cartilage conduction
vibration unit 228 in FIG. The transmission processing unit 222 transmits part of the operator's
voice picked up from the microphone 223 to the reception processing unit 212 as a side tone,
and the reception processing unit 212 uses the voice of the other party from the telephone
communication unit 47 as the operator himself. By superimposing the side tone and outputting
to the earphone 213, the balance between bone conduction and air conduction of one's own
voice in a state in which the mobile phone 301 is placed on the ear is brought close to a natural
state.
[0049]
The voice transmission processing unit 222 further outputs a part of the operator's voice picked
up from the microphone 223 to the sound quality adjustment unit 238. The sound quality
adjustment unit 238 makes the sound quality of the voice of the voice to be output from the
cartilage conduction vibration unit 228 and to be transmitted to the cochlea similar to the sound
quality of the operator's own voice transmitted to the cochlea by internal conduction from the
vocal cords at the time of earplugging Make adjustments and make both cancellations effective.
Then, the phase inversion unit 240 inverts the phase of the voice whose sound quality has been
adjusted in this way, and outputs the phase-inverted voice to the phase adjustment mixer unit
236. When the pressure detected by the pressure sensor 242 is predetermined and the earhole is
closed by the portable telephone 301 by a tragus, the phase adjustment mixer 236 is instructed
from the phase reverser 240 according to an instruction from the controller 239. To drive the
cartilage conduction vibration unit 228. By this, the excessive one's own voice during earplug
bone conduction effect generation is canceled, and a sense of discomfort is alleviated. At this
time, the degree of cancellation is adjusted so that the voices corresponding to the side tones are
left without being canceled. On the other hand, when the pressure detected by the pressure
sensor is low, the phase adjustment mixer unit is instructed by the control unit 239 because the
earhole is not blocked by the tragus and the earplug bone conduction effect does not occur.
Based on this, mixing of the own voice phase inversion output from the phase inversion unit 240
is not performed. In FIG. 8, the positions of the sound quality adjustment unit 238 and the phase
inversion unit 240 may be reversed. Furthermore, the sound quality adjustment unit 238 and the
phase inversion unit 240 may be integrated as a function in the phase adjustment mixer unit
236.

FIG. 9 is a main part conceptual block diagram showing the state in which the mobile phone 301
is applied to the right tragus in Example 4, and illustrates the cancellation of one's own voice
during occurrence of the earplug bone conduction effect. is there. FIG. 9 also illustrates a specific
example of the pressure sensor 242, and is configured on the premise that the cartilage
conduction vibration unit 225 is a piezoelectric bimorph element. The same reference numerals
as in FIGS. 7 and 8 denote the same parts, and a description thereof will be omitted unless
necessary.
[0051]
FIG. 9A shows a state in which the mobile phone 301 is pressed against the tragus 32 to such an
extent that the tragus 32 does not block the earhole 232. In this state, the phase adjustment
mixer unit 236 drives the cartilage conduction vibration unit 225 based on the voice information
of the other party from the reception processing unit 212. The pressure sensor 242 monitors a
signal appearing on a signal line connecting the phase adjustment mixer unit 236 and the
cartilage conduction vibration unit 225, and the cartilage conduction vibration unit (piezoelectric
bimorph element) added according to the pressure on the vibration conductor 227 It is
configured to detect signal changes based on distortion to 225. As described above, when the
cartilage conduction vibration unit 225 for transmitting voice information by contacting the
tragus 32 is formed of a piezoelectric bimorph element, the piezoelectric bimorph element itself
can also be used as a pressure sensor for the tragus 32. The pressure sensor 242 further
monitors a signal appearing on a signal line connecting the phase adjustment mixer unit 236 and
the reception processing unit 212. The signal appearing here is not affected by the pressure on
the tragus 32 and can be used as a reference signal for the pressure determination.
[0052]
As described above, in FIG. 9A, the tragus 32 does not block the earhole 232, and the pressure
determined by the pressure sensor force 242 is small. The phase adjustment mixer unit 236 is
instructed not to mix the phase inversion self voice from the above into the cartilage conduction
vibration unit 225. On the other hand, FIG. 9B shows a state in which the mobile phone 301
presses the tragus 32 more strongly in the direction of the arrow 302, and the tragus 32 blocks
10-05-2019
21
the ear hole 232. And, in this state, the earplug bone conduction effect is generated. The pressure
sensor force 242 determines that the earhole is closed based on the detection of increase in
pressure above a predetermined level, and based on this determination, the control unit 239
causes the phase inversion self voice from the phase inversion unit 240 to be a cartilage
conduction vibration. The phase adjustment mixer unit 236 is instructed to mix in the unit 225.
As described above, the uncomfortable feeling of the player's own voice during the generation of
the earplug bone conduction effect is alleviated. On the other hand, when the pressure sensor
242 detects a decrease in the pressure more than a predetermined level from the state of FIG. 9B,
it is determined that the ear canal is not blocked as shown in FIG. , The mixing of the phase
reversal self voice is stopped. The pressure sensor 242 determines the state transition between
FIG. 9A and FIG. 9B based on the absolute amount of pressure and the change direction of
pressure. In a silent state in which both voices do not exist, the pressure sensor 242 detects
pressure by directly applying a pressure monitor signal that can not be heard by the ear to the
bone conduction vibration unit 225 directly.
[0053]
FIG. 10 is a flowchart of the operation of the control unit 239 in the fourth embodiment of FIG.
Since the flow of FIG. 10 has many parts in common with the flow of the first embodiment in FIG.
4, the same step numbers are given to the corresponding parts, and the description will be
omitted unless necessary. FIG. 10 also extracts and illustrates operations centering on related
functions in order to mainly explain the functions of the cartilage conduction vibration unit.
Therefore, as in the case of FIG. 4, there are also operations of the control unit 239 not described
in the flow of FIG. 10, such as general cellular phone functions. In FIG. 10, parts different from
those in FIG. 4 are shown in bold, so these parts will be mainly described below.
[0054]
Step S42 is a summarization of steps S6 and S8 of FIG. 4 and is illustrated including the case of
going straight to the next step without the non-call operation in the non-call processing of step
S42. The contents are the same as step S6 and step S8 of FIG. Step S44 is a combination of steps
S10 and S12 of FIG. 4 and is a step of checking the presence or absence of a call state between
both parties regardless of whether it is an incoming call or a call from the other party. Although
illustrated, the content is the same as step S6 and step S8 of FIG. In the fourth embodiment, since
there is no configuration for opening and closing the mobile phone 301, the step corresponding
to step S16 in FIG. 4 is not included.
10-05-2019
22
[0055]
Step S46 relates to the first additional function in the fourth embodiment, and checks whether
the mobile phone 301 is stationary in the horizontal state after leaving the hand-held state for a
predetermined time (for example, 0.5 seconds). When the proximity sensor is detected in step
S22, if it is confirmed in step S46 that such a horizontal stationary state is not established, the
process proceeds to step S48 and the cartilage conduction vibration source 225 is turned on. On
the other hand, when the horizontal stationary state is detected in step S46, the process proceeds
to step S50, the cartilage conduction vibration source 225 is turned off, and the process returns
to step S14. Step S50 corresponds to when the cartilage conduction vibration source is on and
step S46 is detected in the repetition of the flow to be described later, and the horizontal
conduction state is detected, and the step is performed with the cartilage conduction vibration
source off. When S50 is reached, the process returns to step S14 without doing anything.
[0056]
Step S52 relates to the second additional function in the fourth embodiment, and checks whether
or not the earplug bone conduction effect is generated by pressing the mobile phone 301
strongly against the tragus 32 to close the ear hole 232. It is. Specifically, as shown in FIG. 9, this
is checked based on the presence or absence of a predetermined pressure change by the
pressure sensor 242 and the direction thereof. When it is detected that the earplug bone
conduction effect is generated, the process proceeds to step S54, a phase inversion signal of
one's own voice is added to the cartilage conduction vibration source 225, and the process
proceeds to step S58. On the other hand, when it is detected in step S52 that the earplug bone
conduction effect is not generated, the process proceeds to step S56, and the addition of the
phase inversion signal of one's own voice to the cartilage conduction vibration source 225 is
eliminated. Migrate to In step S58, it is checked whether or not the call state is disconnected. If
the call is not disconnected, the process returns to step S22, and steps S22 and S46 to step S58
are repeated until a call disconnection is detected in step S58. This responds to the occurrence
and disappearance of the earplug bone conduction effect during a call.
[0057]
The various features of each of the embodiments described above are not limited to the
individual embodiments, and can be replaced or combined with the features of the other
10-05-2019
23
embodiments as appropriate. For example, in the flowchart of the fourth embodiment in FIG. 10,
there is no configuration for switching between the cartilage conduction vibration unit for the
right ear and the cartilage conduction vibration unit for the left ear in the flowchart of the first
embodiment of FIG. The right ear cartilage conduction vibration unit 24 and the left ear cartilage
conduction vibration unit as in the first embodiment are adopted as the configuration of the
conduction vibration unit 228, and the loop of step S22 and step S46 to step S58 is repeated in
the ear. In addition to the response to the occurrence and disappearance of the thrombus guiding
effect, the response to the hand-held change of the mobile phone between the right ear call state
and the left ear call state is also performed by the function according to step S24 to step S26 of
FIG. It may be configured as follows. Further, it is possible to add the check of the horizontal
stationary state and the off function of the cartilage conduction vibration unit in the fourth
embodiment of FIG. 10 to the first to third embodiments. Furthermore, in Examples 1 to 3, it is
also possible to adopt a cartilage conduction vibration unit as in Example 4.
[0058]
FIG. 11 is a perspective view showing Example 5 of the mobile phone according to the
embodiment of the present invention. The fifth embodiment is based on the fourth embodiment
of FIG. 7 and most of the structure is common, so the corresponding parts are assigned the same
reference numerals and descriptions thereof will be omitted. Further, in the part for which the
description is omitted, the numbering itself is omitted to avoid complexity in the illustration, but
the functions and names of the parts common to the drawings are the same as those in FIG. Note
that the block diagram of the fourth embodiment in FIGS. 8 and 9 is basically used for the
detailed configuration. The first difference between the fifth embodiment and the fourth
embodiment is that a so-called touch panel function (a large screen 205 on which an operation
unit 209 such as a ten key is displayed with a finger is touched with a finger on the mobile phone
401 to detect its touch position and slide) It is possible to set to turn off the GUI operation
function) and to have a push / push button 461 that is enabled only when the touch panel
function is set to be off. The OFF setting of the touch panel function can be performed by the
operation of the touch panel itself, and the reset setting to ON of the touch panel function can be
performed by pressing the push button 461 for a predetermined time or more. Further, the push
button 461 has a function of starting a call by pressing the first time when this is enabled, and
disconnecting the call by pressing the second time during the call. The first press of the push
button 461 is performed when making a call to a specific party or when responding to an
incoming call, and in either case, a call is started.
[0059]
10-05-2019
24
A second point in which the fifth embodiment differs from the fourth embodiment is that the fifth
embodiment is configured to function by combining the mobile phone 401 and the soft cover
463 for storing the same. Note that although FIG. 11 illustrates that the soft cover 463 is
transparent for the convenience of the description of the configuration, the soft cover 463 is
actually opaque and the mobile phone 401 is not as shown in FIG. With the soft cover 463
housed, the mobile phone 401 can not be seen from the outside.
[0060]
The function of the push push button 461 can also be performed by pressing the push push
button from above the soft cover 463 in a state where the mobile phone 401 is housed in the
soft cover 463. Furthermore, the soft cover 463 interlocks with the cartilage conduction
vibration unit having the cartilage conduction vibration source 225 of the mobile telephone 401
and the vibration conductor 227 so that a call can be made in a state where the mobile telephone
401 is housed in the soft cover 463 Configured This will be described below.
[0061]
The soft cover 463 is an elastic material (a silicone-based rubber, a mixture of a silicone-based
rubber and a butadiene-based rubber), a natural rubber, or a structure in which an air bubble is
sealed thereto, or a transparent packaging sheet And other air bubbles as in a structure
separated by a thin film of synthetic resin and sealed, etc.), and the vibration conduction which
transmits the vibration from the cartilage conduction vibration source 225 when the mobile
phone 401 is accommodated. The body 227 contacts its inside. Then, by placing the outer side of
the soft cover 463 on the ear while storing the mobile phone 401, the vibration of the vibration
conductor 227 is transmitted to the ear cartilage over a wide contact area through the soft cover
463. Furthermore, the sound from the outer surface of the soft cover 463 resonated by the
vibration of the vibration conductor 227 is transmitted from the external ear canal to the
tympanic membrane. By this, the sound source information from the cartilage conduction
vibration source 225 can be heard as a loud sound. In addition, since the soft cover 463 applied
to the ear closes the ear canal, environmental noise can be blocked. Furthermore, increasing the
force of pressing the soft cover 463 to the ear results in almost complete closure of the ear canal,
and the sound source information from the cartilage conduction vibration source 225 can be
heard as a louder sound by the earplug bone conduction effect. In addition, although it becomes

bone conduction effect is generated based on pressing force detection by the cartilage

conduction vibration source 225, a voice from the microphone A phase inversion signal addition
to the signal is performed.
[0062]
When the cellular phone 401 is in a telephone call state accommodated in the soft cover 463, the
vibration of the vibration conductor 227 transmitted to the soft cover 463 may be transmitted to
the transmitter 23 to cause howling. As a countermeasure, in order to cut off the acoustic
conduction between the vibration conductor 227 and the transmission part 23, the soft cover
463 is provided with an insulating ring part 465 between which the acoustic impedance is
different from that of the soft cover main body. The insulating ring portion 465 can be formed by
integrally molding or joining a material different from the material of the soft cover body. In
addition, the insulating ring portion 465 may be formed by bonding layers of different acoustic
impedances to the outside or the inside of a soft cover molded of the same material. Furthermore,
a plurality of insulating ring portions 465 may be interposed between the vibration conductor
227 and the transmitting portion 23 to enhance the insulating effect.
[0063]
Further, the soft cover 463 is configured as a microphone cover portion 467 in which the vicinity
of the microphone 23 does not interfere with the air conduction of the voice in order to enable a
call in a state where the mobile phone 401 is stored. Such a microphone cover unit 467 has a
sponge-like structure such as an earphone cover, for example.

FIG. 12 is a flowchart of the operation of the control unit 239 (for FIG. 8) in the fifth embodiment
of FIG. In the flow of FIG. 12, the same steps as those in FIG. 10 carry the same step numbers,
and the explanation thereof will be omitted. FIG. 12 also extracts and illustrates operations
centering on related functions in order to mainly explain the functions of the cartilage
conduction vibration unit. Therefore, as in FIG. 10 and the like, in the fifth embodiment, the
operation of the control unit 239 not shown in the flow of FIG.
[0065]
10-05-2019
26
In the flow of FIG. 12, in step S62, it is checked whether or not the touch panel is turned off by
the operation described above, and if it is not turned off, the process proceeds to step S64 to
invalidate the push push button 461 function. Then, the process proceeds to step S66, and
reaches step S34. The portion shown as normal processing in step S66 is the step S14, step S18
to step S22, step S32, step S36 and step S38 to step S58 in FIG. 10 (ie, the portion between step
SS4 and step S34). ) Collectively. In other words, when the process proceeds from step S62 to
step S64, the flow of FIG. 12 executes the same function as that of FIG.
[0066]
On the other hand, when it is detected in step S62 that the touch panel OFF setting is performed,
the flow moves to step S68, the function of the push / push button 461 is validated, and the
process proceeds to step S70. In step S70, the function of the touch panel is invalidated, and in
step S72, it is detected whether or not the push button 461 is pressed for the first time. If no
pressing is detected here, the process proceeds directly to step S34. On the other hand, when the
first pressing of the push button 461 is detected in step S72, the process proceeds to step S74,
and it is detected whether the mobile phone 401 is accommodated in the soft cover 463. This
detection is possible, for example, by the functions of the infrared light emitting units 19 and 20
and the infrared light proximity sensor 21 that constitute the proximity sensor.
[0067]
When storage in the soft cover 463 is detected in step S74, the flow proceeds to step S76, and
the transmitting unit 23 is turned on and the receiving unit 13 is turned off. Further, in step S78,
the cartilage conduction vibration source 225 is turned on, and the process proceeds to step S80
to place the portable telephone 401 in a call state. If it is already in a call state, this is continued.
On the other hand, if storage in the soft cover 463 is not detected in step S74, the process
proceeds to step S82 to turn on both the transmitting unit 23 and the receiving unit 13 and then
to turn off the cartilage conduction vibration source 225 in step S84 to perform step S80. Go to
In step S86 following step S80, the earplug bone conduction effect processing is performed, and
the process proceeds to step S88. The earplug bone conduction effect processing in step S86 is
illustrated by collectively showing steps S52 to S56 in FIG.
[0068]
10-05-2019
27
In step S88, the presence or absence of the second pressing of the push button 461 is detected. If
there is no detection, the flow returns to step S74, and steps S74 to S88 are repeated unless the
second push of the push button 461 is detected. Since it is always checked whether or not the
mobile phone 401 is housed in the soft cover 463 during this repetition during a call, the user,
for example, is in the middle of a call when the environmental noise is large and it is difficult for
the receiver 13 to hear the sound. By storing the mobile phone 401 in the soft cover 463, it is
possible to take measures such as blocking environmental noises and making it easier to hear
sounds by the ear plug bone conduction effect.
[0069]
On the other hand, when the second pressing of the push button 461 is detected in step S88, the
flow moves to step S90, disconnects the call, and turns off all transmission / reception functions
in step S92, and reaches step S34. Since it is checked in step S34 whether the main power is off,
if the main power off is not detected, the flow returns to step S62, and steps S62 to S92 and step
S34 are repeated. Then, in this repetition, since the process to cancel the touch panel OFF setting
by the touch panel operation or the OFF setting by the long push on the push push button 461 is
performed in step S64, switching to the normal processing may be performed as appropriate. it
can.
[0070]
FIG. 13 is a perspective view showing Example 6 of the mobile phone according to the
embodiment of the present invention. 13 (A) is a front perspective view similar to FIG. 7, but as
described later, since Example 6 is configured as a digital camera having a cellular phone
function, it is rotated by 90 degrees with respect to FIG. It is illustrated by the angle of the use
condition as a digital camera. FIG. 13 (B) is a rear perspective view (a front perspective view
when viewed as a digital camera), and FIG. 13 (C) is a cross-sectional view taken along line BB in
FIG. 13 (B).
[0071]
The sixth embodiment is also based on the fourth embodiment of FIG. 7 and most of the
10-05-2019
28
structure is common, so the corresponding parts are assigned the same reference numerals and
descriptions thereof will be omitted. Further, in the part for which the description is omitted, the
numbering itself is omitted to avoid complexity in the illustration, but the functions and names of
the parts common to the drawings are the same as those in FIG. Note that the block diagram of
the fourth embodiment in FIGS. 8 and 9 is basically used for the detailed configuration. The first
point in which the sixth embodiment differs from the fourth embodiment is that the mobile
phone 501 is configured as a digital camera having a mobile phone function. That is, as shown in
FIG. 13B, the zoom lens 555 having high optical performance is adopted as an imaging lens of
the rear main camera. The zoom lens 555 protrudes in a state shown by an alternate long and
short dash line in FIG. 13B when in use, but retracts to a position flush with the outer surface of
the mobile phone 501 when not in use. It has a configuration. In addition, a strobe 565 and a
shutter release button 567 for projecting auxiliary light when the subject is dark are provided.
The mobile phone 501 also has a grip 563 suitable for holding the camera with the right hand.
[0072]
A second point in which the sixth embodiment differs from the fourth embodiment is that the
grip portion 563 has a similar acoustic impedance to the ear cartilage in the same manner as the
soft cover 463 in the fifth embodiment (silicone rubber, silicone rubber And a mixture of
butadiene based rubber, natural rubber, or a structure in which an air bubble is sealed in them,
and having elasticity suitable for a good grip feeling. Further, unlike the arrangement of the
fourth embodiment, the cartilage conduction vibration source 525 is arranged on the back side
of the grip portion 563. As is clear from the cross section of FIG. 13C, the cartilage conduction
vibration source 525 is in contact with the back surface of the grip portion 563.
[0073]
Therefore, by applying the grip portion 563 to the ear, the vibration of the cartilage conduction
vibration source 525 is transmitted to the ear cartilage over a wide contact area by the presence
of the grip portion 563. Furthermore, the sound from the outer surface of the grip portion 563
resonated by the vibration of the cartilage conduction vibration source 525 is transmitted from
the external ear canal to the tympanic membrane. By this, the sound source information from the
cartilage conduction vibration source 525 can be heard as a loud sound. Further, in the same
manner as in the fifth embodiment, the grip portion 563 applied to the ear blocks the external
ear canal, so that environmental noise can be blocked. Furthermore, as in the fifth embodiment,
when the force pressing the grip 563 against the ear is increased, the external ear canal is almost
completely blocked, and the sound source information from the cartilage conduction vibration
10-05-2019
29
source 525 is further added by the earplug bone conduction effect. It can be heard as a loud
sound. Although the detection is performed through the grip portion 563, in the same manner as
in the fifth embodiment, in a state in which the ear plug bone conduction effect is generated
based on the pressing force detection by the cartilage conduction vibration source 525, A phase
inversion signal addition to the signal is performed.
[0074]
Further, unlike the fourth embodiment, as clearly shown in FIG. 13B, the transmitter 523 is
provided not on the front surface of the mobile phone 501 but on the end surface. Therefore, the
transmitting unit 523 can pick up the user's voice in common when making a call by placing the
earpiece 13 on the ear or making a call by placing the grip 563 on the back side at the ear. The
setting can be switched by the switching button 561 as to whether the reception unit 13 is
enabled or the cartilage conduction vibration source 525 is enabled. In the state where the zoom
lens 555 protrudes in the state shown by the alternate long and short dash line in FIG. 13B, since
the grip portion 563 is not suitable for placing a call on the ear, the switching button is operated
in such a state. When it is set to enable the elastochondral conduction vibration source 525, the
zoom lens 555 is automatically retracted, and the execution of switching is suspended until this
retraction is completed.
[0075]
FIG. 14 is a flowchart of the operation of the control unit 239 (for FIG. 8) in the sixth
embodiment of FIG. In the flow of FIG. 14, the same steps as those in FIG. 10 will be assigned the
same step numbers, and the description thereof will be omitted. FIG. 14 also extracts and
illustrates operations centering on related functions in order to mainly explain the functions of
the cartilage conduction vibration unit. Therefore, in the same manner as in FIG. 10 and the like,
in the sixth embodiment, there are also operations of the control unit 239 not described in the
flow of FIG. 14 such as general cellular phone functions.
[0076]
In the flow of FIG. 14, it is checked whether or not the call start operation has been performed at
step S104. And if there is no operation, it will transfer to step S34 immediately. On the other
hand, when the call start operation is detected, the process proceeds to step S106, and it is
10-05-2019
30
checked whether the cartilage conduction setting is made by the switching button 561. If it is the
cartilage conduction setting, it is checked in step S108 whether the zoom lens 555 is projecting.
As a result, if there is no projection of the zoom lens 555, the process proceeds to step S110, the
transmitting unit 523 is turned on and the receiving unit 13 is turned off, the cartilage
conduction vibration source 525 is turned on in step S112, and the process proceeds to step
S46.
[0077]
On the other hand, when the cartilage conduction setting is not detected in step S106, the
process proceeds to step S114, the transmitting unit 523 and the receiving unit 13 are turned on
together, the cartilage conduction vibration source 525 is turned off in step S116, and the
process proceeds to step S118. Furthermore, even when the cartilage conduction setting is
detected in step S106, if it is detected in step S108 that the zoom lens 555 is projecting, the
process proceeds to step S110, instructs retraction of the zoom lens 555, and proceeds to step
S114. Transition. If retraction has already been started, the continuation is instructed. As will be
described later, steps S106 to S116 are repeated as long as the call state is not cut off. In this
manner, after the retraction is instructed in step S110 according to the detection of the cartilage
conduction setting in step S106, and after the retraction is started, the retraction is completed
and step S110 is performed until the protrusion of the zoom lens 555 is not detected in step
S108. The state of step S114 and step S116 is maintained.
[0078]
Steps S46 to S56 following step S112 are the same as those in FIG. When the process proceeds
from step S54 or step S56 to step S118, it is checked whether or not the call state is
disconnected, and if no call disconnection is detected, the flow returns to step S106, and
thereafter, from step S106 to step S118 and step S46 to step S56 is repeated. By this, for
example, when the environmental noise is large and it is difficult for the receiver 13 to hear the
sound, the user operates the switching button 561 during the call to switch to the cartilage
conduction setting, thereby blocking the environmental noise, or It is possible to take measures
such as making the sound easier to hear by the guidance effect. Also, at this time, if the zoom
lens 555 is in the projecting state, it is automatically retracted.

FIG. 15 is a perspective view showing Example 7 of the mobile phone according to the
embodiment of the present invention. The mobile phone 601 of the seventh embodiment is
configured such that the upper portion 607 can be folded over the lower portion 611 by the
hinge portion 603 in the same manner as the first embodiment. 15A is a front perspective view
similar to FIG. 1, and FIG. 15B is a rear perspective view thereof. Moreover, FIG.15 (C) is principal
part sectional drawing in the BB cut surface in FIG. 15 (B). Most of the structure of the seventh
embodiment is the same as that of the first embodiment, so the corresponding parts are assigned
the same reference numerals and descriptions thereof will be omitted. Further, for the part
whose description is omitted, the numbering itself is omitted to avoid the complexity of the
illustration, but the function and the name of the part common to the drawings are the same as
those in FIG. Although the overview is the same as that of the first embodiment, the block
diagram of the fourth embodiment in FIGS. 8 and 9 is basically used for the detailed internal
configuration.
[0080]
The first point in which the seventh embodiment differs from the first embodiment is that a
cartilage conduction output portion 663 having a large area is provided on the hinge vicinal side
of the upper portion 607 as shown in FIG. 15 (B). Similar to the soft cover 463 in the fifth
embodiment and the grip unit 563 in the sixth embodiment, the cartilage conduction output unit
663 is a material having similar acoustic impedance to ear cartilage (silicone rubber, silicone
rubber and butadiene rubber). , Natural rubber, or a structure in which an air bubble is sealed in
them, and the outer wall of the mobile phone 601 has elasticity suitable for protecting foreign
matter from colliding. Further, unlike the arrangement of the first embodiment, the cartilage
conduction vibration source 625 is arranged on the back side of the cartilage conduction output
unit 663. As is clear from the cross section of FIG. 15C, the cartilage conduction vibration source
625 is in contact with the back surface of the cartilage conduction output portion 663.
[0081]
Therefore, by folding the cellular phone 601 and applying the cartilage conduction output unit
663 to the ear, the vibration of the cartilage conduction vibration source 625 is transmitted to
the ear cartilage over a wide contact area by the presence of the cartilage conduction output unit
663. Furthermore, the sound from the outer surface of the cartilage conduction output unit 663
resonated by the vibration of the cartilage conduction vibration source 625 is transmitted from
the ear canal to the tympanic membrane. As a result, the sound source information from the
10-05-2019
32
cartilage conduction vibration source 625 can be heard as a loud sound. Further, in the same
manner as in the fifth and sixth embodiments, since the cartilage conduction output portion 663
applied to the ear blocks the external ear canal, environmental noise can also be blocked.
Furthermore, as in the fifth and sixth embodiments, increasing the pressing force of the cartilage
conduction output unit 663 to the ear results in almost complete closure of the external ear
canal, and the cartilage conduction vibration source 625 by the ear plug bone conduction effect.
The sound source information from can be heard as a louder sound. Although the detection is
performed via the cartilage conduction output unit 663, as in the fifth and sixth embodiments, in
a state in which the ear plug bone conduction effect is generated based on the pressing force
detection by the cartilage conduction vibration source 625. , And the phase inversion signal
addition to the voice signal from the microphone is performed.
[0082]
The second point in which the seventh embodiment differs from the first embodiment is that, as
shown in FIG. 15A, the transmitter 623 is provided not on the front of the lower portion 607 of
the mobile phone 601 but on the lower end surface of the lower portion 607. That is the point.
Therefore, even when the mobile phone 601 is opened and the receiver 13 is put on the ear to
make a call, and the mobile phone 601 is closed and the cartilage conduction output part 663 is
put on the ear to make the call, the transmitter 623 is common. The voice of the user can be
picked up. When the portable telephone 601 is set to support cartilage conduction switching, the
receiver 13 becomes effective when the portable telephone is opened and the cartilage
conduction vibration source 525 is automatically activated when the portable telephone is
closed. Switch over. On the other hand, when the cartilage conduction switching setting is not set,
the cartilage conduction vibration source 525 is not automatically activated, and normal
transmission and reception functions regardless of the opening and closing of the mobile phone.
[0083]
As is apparent from the rear perspective view of FIG. 15B, the rear main camera 51, the speaker
51, and the rear display unit 671 are provided on the rear of the mobile phone 601.
Furthermore, on the back of the mobile phone 601, a push-push button 661 is provided which is
enabled when the cartilage conduction switching setting is made and the mobile phone 601 is
closed. The push-push button 661 has a function of starting a call by pressing the first time as in
the fifth embodiment and disconnecting the call by pressing the second time during the call. The
first press of the push button 661 is performed when making a call to a specific party or when
responding to an incoming call, and in either case, a call is started.

[0084]
FIG. 16 is a flowchart of the operation of the control unit 239 (for FIG. 8) in the seventh
embodiment of FIG. In the flow of FIG. 16, the same steps as those in FIG. 14 carry the same step
numbers, and the explanation thereof will be omitted. FIG. 16 also extracts and illustrates
operations centering on related functions in order to mainly explain the functions of the cartilage
conduction vibration unit. Therefore, in the same manner as FIG. 14 and the like, in the seventh
embodiment, there are also operations of the control unit 239 not described in the flow of FIG.
16 such as general cellular phone functions.
[0085]
In the flow of FIG. 16, when the call is started and the process goes to step S122, it is checked
whether the cartilage conduction switching correspondence setting is made. Then, when the
cartilage conduction switching correspondence setting is confirmed in step S122, the process
proceeds to step S124, and it is opened as shown in FIG. 15 from the state where the mobile
phone is open, that is, the upper portion 607 overlaps the lower portion 611 and is folded. Check
if it is Then, when it is confirmed that the mobile phone 601 is not opened and the upper portion
607 is in a state of being folded over the lower portion 611 and the process proceeds to step
S110, the transmitting unit 523 is turned on and the receiving unit 13 is turned off. At step
S112, the cartilage conduction vibration source 525 is turned on, and the process proceeds to
step S46. In this way, reception by the cartilage conduction output unit 663 becomes possible in
a state where the mobile phone 601 is folded.
[0086]
On the other hand, when the setting for supporting cartilage conduction switching is not detected
in step S122, the process proceeds to step S114 without asking whether the telephone set 601 is
folded or not, and the transmitting unit 523 and the receiving unit 13 are turned on. The
cartilage conduction vibration source 525 is turned off, and the process proceeds to step S118.
Furthermore, when the cartilage conduction switching correspondence setting is detected in step
S106 and also when it is confirmed in step S124 that the mobile phone 601 is open, the process
proceeds to step S114.
10-05-2019
34
[0087]
Also in the flow of FIG. 16, it is checked whether the call state is disconnected in step S118, and
if the call disconnection is not detected, the flow returns to step S122, and thereafter, step S122,
step S124, step S114 to step S118 and Steps S46 to S56 are repeated. In this way, when the
setting for supporting cartilage conduction switching is made in advance, the user folds the
mobile phone 601 during a call, for example, when environmental noise is large and it is difficult
for the receiver 13 to hear the sound, and the cartilage conduction output unit By switching to
the reception by 663, it is possible to take measures such as blocking environmental noise and
making it easier to hear sound by the earplug bone conduction effect.
[0088]
Summarizing the features of the fifth to sixth embodiments, the mobile phone has a cartilage
conduction vibration source and a conductor for guiding the vibration of the cartilage conduction
vibration source to the ear cartilage, and the conductor is configured as an elastic body. Or a size
contacting with the ear cartilage at a plurality of locations or a size closing the ear canal in
contact with the ear cartilage, or at least an area approximating the earlobe, or approximating the
acoustic impedance of the ear cartilage It has an acoustic impedance. Then, sound information
from the cartilage conduction vibration source can be effectively heard by any one or a
combination of these features. Moreover, utilization of these features is not limited to the above
embodiment. For example, by utilizing the advantages of the material, size, area, arrangement,
and structure disclosed in the above embodiments, it is possible to configure the present
invention without making the conductor elastic.
[0089]
FIG. 17 is a perspective view showing Example 8 of the mobile phone according to the
embodiment of the present invention. The eighth embodiment is configured as a digital camera
having a cellular phone function as in the sixth embodiment of FIG. 13, and is a front perspective
view of FIG. 17 (A) and FIG. 17 (B) in the same manner as FIG. FIG. 17 (C) is a cross-sectional
view taken along the line B-B in FIG. 17 (B). The majority of the structure of the seventeenth
embodiment is the same as that of the sixth embodiment shown in FIG. 13 and, therefore,
corresponding parts are denoted with the same reference numerals and description thereof is
omitted.
10-05-2019
35
[0090]
The eighth embodiment differs from the sixth embodiment in that the cartilage conduction
vibration source 725 is embedded in the grip portion 763 as is apparent from the cross section
of FIG. 17 (C). The grip 763 is, as in Example 6 of FIG. 13, a material (a silicone-based rubber, a
mixture of a silicone-based rubber and a butadiene-based rubber, a natural rubber, or an air
bubble sealed thereto) ) And has an elasticity suitable for a good grip. Similar to the sixth
embodiment, the internal detailed configuration basically employs the block diagram of the
fourth embodiment in FIGS. 8 and 9.
[0091]
A flexible connection line 769 in FIG. 17C connects the cartilage conduction vibration source
725 embedded in the grip portion 763 and a circuit portion 771 such as the phase adjustment
mixer portion 236 in FIG. 8. The embedded structure of the cartilage conduction vibration source
725 inside the grip part 763 as shown in FIG. 17C can be realized by integral molding in which
the cartilage conduction vibration source 725 and the flexible connection line 769 are inserted
into the grip part 763. is there. Alternatively, the grip portion 763 may be divided into two parts
with the flexible connection line 769 and the cartilage conduction vibration source 725 as a
boundary, and the grip portion 763 may be realized by bonding the both with the flexible
connection line 769 and the cartilage conduction vibration source 725 interposed therebetween.
.
[0092]
In Example 8, the vibration of the cartilage conduction vibration source 725 is transmitted to the
ear cartilage over a wide contact area through the grip portion 763 by applying the grip portion
763 to the ear, and resonance occurs by the vibration of the cartilage conduction vibration
source 725 The sound from the outer surface of the grip 763 is transmitted from the external
ear canal to the tympanic membrane, and the grip 763 applied to the ear blocks the external ear
canal to block environmental noise, and the grip 763 is pressed against the ear As the power is
increased, the external ear canal is almost completely blocked, and it is similar to the sixth
embodiment that the sound source information from the cartilage conduction vibration source
725 can be heard as a louder sound by the earplug bone conduction effect. Further, based on the
10-05-2019
36
pressing force detection by the cartilage conduction vibration source 525, addition of a phase
inversion signal to the own voice signal from the microphone is performed in a state in which the
earplug bone conduction effect is generated as in the sixth embodiment is there. In Example 8,
since the cartilage conduction vibration source 725 is embedded in the grip portion 763,
distortion of the cartilage conduction vibration source 725 caused by the distortion of the grip
portion 763 due to an increase in pressing force causes the ear plug bone conduction effect. Is
detected.
[0093]
In the eighth embodiment, the significance of embedding the cartilage conduction vibration
source 725 inside an elastic body such as the grip 763 is to take measures against the impact on
the cartilage conduction vibration source 725 in addition to obtaining good sound conduction as
described above. It is in. The piezoelectric bimorph element used as the cartilage conduction
vibration source 725 in the eighth embodiment has the property of dislike shock. Here, by
constructing the cartilage conduction vibration source 725 from the periphery as in the eighth
embodiment, it is possible to buffer shocks applied to the rigid structure of the mobile phone,
and the mobile phone is always exposed to the risk of falling or the like. Implementation can be
facilitated. The elastic body that encloses the cartilage conduction vibration source 725 not only
functions as a shock absorbing material, but also functions as a structure to more effectively
transmit the vibration of the cartilage conduction vibration source 725 to the ear as described
above.
[0094]
FIG. 18 is a perspective view showing Example 9 of the mobile phone according to the
embodiment of the present invention. The mobile phone 801 of the ninth embodiment is
configured such that the upper portion 807 can be folded over the lower portion 611 by the
hinge portion 603 in the same manner as the seventh embodiment. 18A is a front perspective
view, FIG. 18B is a rear perspective view, and FIG. 18C is a sectional view taken along the line B-B in FIG. 18B in the same manner as FIG. FIG. Since the eighth embodiment of FIG. 18 shares
most of the structure with the seventh embodiment of FIG. 15, the corresponding parts are
denoted by the same reference numerals and description thereof is omitted.
[0095]
10-05-2019
37
The ninth embodiment differs from the seventh embodiment in that the cartilage conduction
vibration source 825 is sandwiched between the cartilage conduction output portion 863 and the
internal buffer 873 as is clear from the cross section of FIG. 18C. Similar to the cartilage
conduction output portion 663 in the seventh embodiment, this cartilage conduction output
portion 863 is a material (acoustic rubber, silicone rubber, a mixture of silicone rubber and
butadiene rubber, natural rubber, or the like) in which ear cartilage and acoustic impedance
approximate each other. It is made of an air bubble sealed structure) and has elasticity suitable
for protecting foreign matter from colliding with the outer wall of the cellular phone 601.
Further, the internal buffer 873 can be made of any material as long as it is an elastic body for
the purpose of buffering, but can be made the same material as the cartilage conduction output
part 863. Similar to the seventh embodiment, the internal detailed configuration basically uses
the block diagram of the fourth embodiment in FIGS. 8 and 9.
[0096]
As shown in the cross section of FIG. 18C, a cartilage conduction vibration source 825 and a
flexible connection line 869 are sandwiched between the cartilage conduction output unit 863
and the internal buffer 873. Similar to the eighth embodiment, this flexible connection line 869
connects the cartilage conduction vibration source 825 to the circuit portion 871 such as the
phase adjustment mixer unit 236 shown in FIG. The structure for sandwiching the cartilage
conduction vibration source 825 and the flexible connection line 869 between the cartilage
conduction output unit 863 and the internal buffer 873 is integrated in the cartilage conduction
output unit 875, and such a cartilage conduction output unit 875 It is embedded in the upper
portion 807 of the mobile phone 801.
[0097]
Also in the ninth embodiment, the vibration of the cartilage conduction vibration source 825 is
transmitted to the ear cartilage in a wide contact area by interposing the cartilage conduction
output portion 863 by applying the cartilage conduction output portion 863 to the ear; the
cartilage conduction vibration source 825 Sound transmitted from the cartilage conduction
output unit 863 resonating by the vibration of the ear to the tympanic membrane from the
external auditory canal, and the cartilage conduction output unit 863 applied to the ear blocks
the external auditory canal, thereby blocking environmental noise, and cartilage When the force
pressing the conduction output portion 863 against the ear is increased, the external ear canal is
almost completely blocked, and it is possible to hear the sound source information from the
10-05-2019

cartilage conduction vibration source 825 as a louder sound by the earplug bone conduction
effect. Is the same as Further, based on pressing force detection by the cartilage conduction
vibration source 525, addition of a phase inversion signal to the own voice signal from the
microphone is performed in a state in which the earplug bone conduction effect is generated as
in the seventh embodiment. is there. In Example 9, since both cartilage conduction vibration
sources 825 are sandwiched between the cartilage conduction output part 863 and the internal
buffer material 873 which are elastic bodies, the cartilage due to increase in pressing force is the
same as in Example 8. The distortion of the cartilage conduction vibration source 825 caused by
the distortion of the conduction output portion 863 detects a state in which the ear plug bone
conduction effect is generated.
[0098]
In Example 9, the significance of the structure in which the cartilage conduction vibration source
825 is sandwiched between the cartilage conduction output part 863 and the internal buffer
material 873, both of which are elastic members, is to obtain good sound conduction as
described above. In addition to the above, it is to be a countermeasure against the shock to the
cartilage conduction vibration source 825 configured by the piezoelectric bimorph. That is, in the
same manner as in the eighth embodiment, the cartilage conduction vibration source 725 is
configured to be surrounded by an elastic body from the periphery, so that shocks applied to the
rigid structure of the mobile phone can be buffered. Implementation on exposed mobile phones
can be facilitated. The elastic body sandwiching the cartilage conduction vibration source 825
not only functions as a buffer material, but also by molding at least the outer elastic body with a
material having an acoustic impedance similar to that of the ear cartilage. It functions as a
configuration to more effectively transmit the vibration of the source 825 to the ear.
[0099]
FIG. 19 is a perspective view showing Example 10 of the mobile phone according to the
embodiment of the present invention. Similar to the fourth embodiment, the mobile phone 901 of
the tenth embodiment is an integrated type without a movable portion, and is configured as a socalled smartphone having a large screen 205 having a GUI function. And since there are many
points in common in the structure, the corresponding parts are assigned the same reference
numerals as in the fourth embodiment, and the explanation will be omitted. In the same manner
as in Example 4, in Example 10 as well, "upper part" does not mean the separated upper part, but
means the upper part of the integral structure.
10-05-2019

[0100]
The tenth embodiment differs from the fourth embodiment in that the cartilage conduction
vibration source 925 including a piezoelectric bimorph element or the like serves as a cartilage
conduction vibration source and also serves as a driving source of a receiver that generates a
sound wave transmitted to the tympanic membrane by air conduction. That is the point.
Specifically, as in the fourth embodiment, the vibration conductor 227 is disposed on the upper
side of the mobile phone in contact with the upper part of the cartilage conduction vibration
source 925. Furthermore, in the front of the cartilage conduction vibration source 925, a
material (acoustic rubber, a mixture of silicone rubber and butadiene rubber, natural rubber, or
the like) in which ear cartilage and acoustic impedance are similar as in Example 7 The cartilage
conduction output part 963 made by the structure which sealed the air bubble is arrange |
positioned. Further, as described later, since the cartilage conduction output unit 963 doubles as
a receiving unit for generating a sound wave transmitted to the tympanic membrane by air
conduction, in the tenth embodiment, there is no separate receiving unit 13 as in the fourth
embodiment.
[0101]
According to the above configuration, first, the vibration of the cartilage conduction vibration
source 925 is laterally transmitted by the vibration conductor 227 and vibrates the both ends
224 and 226, so that either of them is brought into contact with the tragus You can hear the
sound by conduction. In addition, as in the fourth embodiment, the vibration conductor 227
vibrates not only at the right end 224 and the left end 226 but also as a whole. Therefore, also in
the tenth embodiment, audio information can be transmitted regardless of where on the inner
upper end side of the mobile phone 901 is in contact with the ear cartilage. Then, when the
cellular phone 901 is put on the ear in such a manner that a part of the cartilage conduction
output part 963 comes to the front of the entrance of the ear canal as in a normal cellular phone,
the vibration conductor 227 contacts a wide area of the ear cartilage. At the same time, the
cartilage conduction output unit 963 contacts ear cartilage such as tragus. Through such contact,
sounds can be heard by cartilage conduction. Furthermore, in the same manner as in the fifth to
ninth embodiments, the sound from the outer surface of the cartilage conduction output portion
963 resonated by the vibration of the cartilage conduction vibration source 925 is transmitted
from the outer ear canal to the eardrum as a sound wave. In this way, the cartilage conduction
output unit 963 can function as a receiving unit by air conduction in a normal mobile phone use
state.
10-05-2019

[0102]
Cartilage conduction differs in conduction depending on the magnitude of pressure on cartilage,
and a more effective conduction state can be obtained by increasing the pressure. This means
that the natural action of strengthening the pressure of pressing the cell phone to the ear can be
used for volume control if the received sound is difficult to hear. And such a function can be
naturally understood by the user through natural behavior, without explaining to the user by, for
example, an instruction manual. In the tenth embodiment, the vibration of the cartilage
conduction vibration source 925 is configured so that both the vibration conductor 227, which is
a rigid body, and the cartilage conduction output unit 963, which is an elastic body, can
simultaneously contact ear cartilage. In order to make it possible to perform volume control more
effectively through adjustment of the pressing force of the vibration conductor 227, which is
[0103]
The implementation of the present invention is not limited to the above embodiments, and the
various advantages of the present invention described above can be enjoyed in other
embodiments. For example, when the combination of the cartilage conduction output part 963
and the cartilage conduction output part 963 is configured to function as a receiver dedicated to
air conduction in Example 10, the ear cartilage is placed at the position where the cartilage
conduction output part 963 is disposed. It is possible to dispose a resonator suitable as a speaker
other than a material whose acoustic impedance is close to that of the speaker. Also in this case,
in Example 10, the cartilage conduction vibration source 925 comprising a piezoelectric bimorph
element or the like serves as a cartilage conduction vibration source and also functions as a
driving source of a receiver for generating a sound wave transmitted to the tympanic membrane
by air conduction. You can enjoy the benefits.
[0104]
FIG. 20 is a perspective view showing Example 11 of the mobile phone according to the
embodiment of the present invention. Similar to the fourth embodiment, the mobile phone 1001
according to the eleventh embodiment is an integral type without a movable portion, and is
configured as a so-called smartphone having a large screen 205 having a GUI function. And since
there are many points in common in the structure, the corresponding parts are assigned the
same reference numerals as in the fourth embodiment, and the explanation will be omitted. In
10-05-2019
41
the same manner as in Example 4, in Example 10 as well, "upper part" does not mean the
separated upper part, but means the upper part of the integral structure.
[0105]
The eleventh embodiment is different from the fourth embodiment in that the right ear vibration
unit 1024 and the left ear vibration unit 1026 omit the numbers for the side surface 1007 and
the illustrated relationship instead of the front of the mobile phone 1001. It is provided on the
opposite side. (It should be noted that the arrangement of the right ear vibration unit 1024 and
the left ear vibration unit 1026 is opposite to that of the fourth embodiment in FIG. 7).
Functionally, the fourth embodiment is the same as the fourth embodiment. Also in Example 11,
the right ear vibration unit 1024 and the left ear vibration unit 1026 are respectively configured
as both ends of the vibration conductor 1027, and a cartilage comprising a piezoelectric bimorph
element or the like in the lower portion of the vibration conductor 1027. The conductive
vibration source 1025 is disposed in contact and transmits the vibration to the vibration
conductor 1027. Thereby, the vibration of the cartilage conduction vibration source 1025 is
laterally transmitted by the vibration conductor 1027 to vibrate the both ends 1024 and 1026.
Both ends 1024 and 1026 of the vibration conductor 1027 are arranged to be in contact with
the tragus when the upper end portion of the side surface (eg, 1007) of the mobile phone 1001
is put on the ear.
[0106]
In addition, the microphones or other transmitters 1023 can pick up sounds produced by the
user even when either the right ear vibration unit 1024 or the left ear vibration unit 1026 is
applied to the tragus As such, it is provided on the lower surface of the mobile phone 1001. The
mobile phone 1001 according to the eleventh embodiment is provided with a speaker 1013 for a
videophone while observing the display unit 205, and the transmitting unit 1023 such as a
microphone has a sensitivity changeable for a videophone. As a result, it is possible to pick up a
sound pronounced by the user while observing the display unit 205.
[0107]
FIG. 21 is a side view of the mobile phone 1 showing the functions of the right ear vibration unit
1024 and the left ear vibration unit 1026, and the illustrated method conforms to FIG. However,
10-05-2019
42
as described in FIG. 20, in the eleventh embodiment, the right ear vibration unit 1024 and the
left ear vibration unit 1026 are provided on the side surface of the mobile phone 1001,
respectively. Therefore, when the mobile phone 1001 is put on the ear in Example 11, the side of
the mobile phone 1001 is put on the tragus as shown in FIG. That is, since the surface of the
display unit 5 of the mobile phone 1 is not in contact with the tragus as shown in FIG. 2, the
display unit 205 does not touch the ears or cheeks and becomes stained with sebum or the like.
[0108]
Specifically, FIG. 21A shows a state in which the right hand is held with the mobile phone 1001
in the right hand and the right ear 28 is in contact, and the side opposite to that applied to the
ear in the mobile phone 1001 can be seen In addition, the surface of the display unit 205, the
cross section of which is illustrated, is substantially perpendicular to the cheek and faces the
lower back of the face. As a result, as described above, the display unit 205 does not touch the
ears or cheeks and becomes stained with sebum or the like. Similarly, FIG. 21B shows a state in
which the mobile phone 1001 is held in the left hand and applied to the tragus 34 of the left ear
30, and in this case as well as in FIG. It is almost perpendicular to the cheek and faces the lower
back of the face, and the display unit 205 does not hit the ears or cheeks and is not stained with
sebum or the like.
[0109]
In the use state as shown in FIG. 21, for example, in the case of FIG. 21 (A), the band telephone
1001 is moved without twisting the hand as it is while holding the mobile phone 1001 with the
right hand and observing the display portion 205. This is realized by applying the right ear
vibration unit 1024 to the tragus 32. Therefore, the observation state of the display unit 205 and
the vibrator for the right ear 1024 can be made into the tragus 32 by the natural movement of
the right hand that slightly changes the angle between the elbow and the wrist without changing
the hand held mobile phone 1001 or twisting the hand. Transitions between the applied states
are possible. In the above description, the display unit 205 is substantially perpendicular to the
cheek in the state of FIG. 21 for simplification of the description, but the user is free to set the
angle of the hand or the posture for applying the mobile phone 1001 to the ear. The angle of the
cheek of the display unit 205 does not necessarily have to be at a right angle, and may be
appropriately inclined. However, according to the configuration of the eleventh embodiment,
since the right ear vibration unit 1024 and the left ear vibration unit 1026 are provided on the
side of the mobile phone 1001 respectively, the tragus 32 or 34 can be used in any posture. Even
if it is applied to the display unit 205, the display unit 205 does not get dirty with sebum or the
10-05-2019
43
like by hitting the ear or cheek.
[0110]
In the eleventh embodiment, as a result of the display unit 205 not pointing in the direction of
the cheek and being hidden, there is a possibility that the display contents such as the call
destination can be seen by the other person before and after. Therefore, in the eleventh
embodiment, in order to protect privacy, when the right ear vibration unit 1024 or the left ear
vibration unit 1026 is in contact with the ear, switching from the normal display to the privacy
protection display (for example, no display) is automatically performed. To be done. The details
will be described later.
[0111]
FIG. 22 is a perspective view showing a twelfth example of the mobile phone according to the
embodiment of the present invention. FIG. 22A shows a state in which a handle 1181 described
later does not protrude, and FIG. 22B shows a state in which the handle 1181 protrudes. In the
mobile phone 1101 of the twelfth embodiment, as in the eleventh embodiment, the cartilage
conduction vibration unit 1124 is a side surface of the mobile phone 1101 (the side surface on
the left side as viewed in FIG. 22). Because it is not provided with a number). The mobile phone
according to the twelfth embodiment is based on an integrated mobile phone having no movable
portion as in the eleventh embodiment, and is configured as a so-called smartphone having a
large screen 205 having a GUI function. And since there are many points in common in the
structure, the corresponding parts are assigned the same reference numerals as in the eleventh
embodiment, and the explanation will be omitted. In the same manner as in Example 11, in
Example 10, "upper part" does not mean the separated upper part, but means the upper part of
the integral structure.
[0112]
The twelfth embodiment differs from the eleventh embodiment in that a cartilage conduction
vibration unit 1124 is provided on the side surface on the left side as viewed in FIG. . In addition,
since what is applied to the ear is limited to the side surface on the left side, a transmitter unit
1123 such as a microphone is also provided on the lower surface close to the left side surface of
the mobile phone 1101 as shown in FIG. Also in the twelfth embodiment, in the case of a
10-05-2019
44
videophone call while observing the display unit 205, switching of the transmitting unit 1023 is
performed to pick up voices pronounced by the user who is observing the display unit 205. Can.
[0113]
In the twelfth embodiment, the cartilage conduction vibration unit 1124 can be applied to the
tragus of the right ear similarly to the eleventh embodiment from the state where the display unit
205 is visible as shown in FIG. On the other hand, in order to apply the cartilage conduction
vibration unit 1124 to the tragus of the left ear, the soft cartilage conduction vibration unit 1124
can be made to face the left ear by switching the mobile phone 1101 so that it faces back. . Such
use is also possible in the state where the handle 1181 is not protruded as shown in FIG. 22 (A).
[0114]
Next, the function of the handle will be described. One natural way of holding the cartilage
conduction vibration unit 1124 to the ear at an angle such that the display surface 205 is
substantially perpendicular to the cheek as shown in FIG. 21 is the mobile phone 1101 provided
with the display unit 205. The thumb and other four fingers sandwich the front and back of the
screen, but at this time the display unit 205 is touched by the finger, which may cause a
malfunction and a relatively long and strong contact during a call. There is a risk of fingerprint
stains.
[0115]
Therefore, in Example 12, in order to facilitate holding of the mobile phone 1101 while
preventing finger touch on the display unit 205, the state of FIG. 22A is changed to the state of
FIG. 22B as necessary. The handle 1181 is made to project, and the handle 1181 can be used for
holding. Thus, in the state of FIG. 22B, the handle 1181 and the body end of the mobile phone
1101 can be held between the thumb and the other four fingers, and the mobile phone 1101 is
easily held without touching the display portion 205. be able to. Further, in the case where the
projection amount is configured to be relatively large, the mobile phone 1101 can be held by
gripping the handle 1181. As in the case of the state of FIG. 22A, the cartilage conduction
vibration unit 1124 can be applied to the tragus of the left ear by holding the mobile phone
1101 so as to face the back.
10-05-2019
45
[0116]
In order to cause the handle to protrude from FIG. 22A, the lock of the handle is released by
pushing the protrusion operation button 1183 and slightly protrudes, so that the state shown in
FIG. 22B can be obtained by pulling out the drawing. . Since locking occurs in the state of FIG.
22B, there is no hindrance when pressing the cartilage conduction vibration unit 1124 against
the tragus by holding the handle 1181. Since the lock is released by pushing the protrusion
operation button 1183 in the state of FIG. 22B in order to store the handle 1181, the lock is
engaged by pressing the handle 1181 so as to be in the state of FIG.
[0117]
FIG. 23 is a flowchart of the operation of the control unit 239 (for FIG. 8) in the twelfth
embodiment of FIG. Since the flow in FIG. 23 has many parts in common with the flow in FIG. 14,
the same step numbers are given to the corresponding parts and the description is omitted. FIG.
23 also extracts and illustrates operations centering on related functions in order to mainly
explain the functions of the cartilage conduction vibration unit. Therefore, as in FIG. 14 and the
like, in the twelfth embodiment, there are also the operations of the control unit 239 not
described in the flow of FIG. 23, such as the functions of a general mobile phone. Parts in FIG. 23
different from those in FIG. 14 are shown in bold, so these parts will be mainly described below.
[0118]
In the flow of FIG. 23, it is checked whether or not the call start operation has been performed at
step S104. And if there is no operation, it will transfer to step S34 immediately. On the other
hand, when the call start operation is detected, the process proceeds to step S132, and it is
checked whether the handle 1181 is in the projecting state. If not, the process proceeds to step
S134 to check whether the cartilage conduction vibration unit 1124 is in contact with the ear
cartilage. And if a contact state is detected, it will progress to step S136. When it is detected in
step S132 that the handle 1181 is in the projecting state, the process immediately proceeds to
step S136.
[0119]
10-05-2019
46
At step S136, the transmitter 1123 is turned on, and at step S138, the cartilage conduction
vibration unit 1124 is turned on. On the other hand, at step S140, the speaker 1013 is turned
off. Next, in step S142, the display on the display unit 205 is used as a privacy protection display.
This privacy protection indication is a predetermined indication that does not include privacy
information or is in a non-display state. At this point, only the display content is changed without
turning off the display unit 205 itself. After performing such display control, the process
proceeds to step S52. If it is already in the target state in step S 136 to step S 142, as a result,
nothing is done in these steps and step S 52 is reached.
[0120]
On the other hand, when it is not detected that the cartilage conduction vibration unit 1124 is in
contact with the ear cartilage in step S134, the process proceeds to step S144 to turn on the
transmitting unit 144 and also for cartilage conduction in step S146. The vibration unit 1124 is
turned off. On the other hand, at step S148, the speaker 1013 is turned on. Next, in step S150,
the display of the display unit 205 is set as a normal display. After performing such display
control, the process proceeds to step S118. Also in step S144 to step S150, if the target state has
already been reached, nothing is performed in these steps as a result, and the process reaches
step S118.
[0121]
Steps S52 to S56 following step S142, steps S118 and S34, and steps S118 and S34 following
150 are the same as those in FIG. When the process proceeds to step S118, a check is made as to
whether or not the call state is disconnected, and if no call disconnection is detected, the flow
returns to step S132, and thereafter, steps S132 to S150 and steps S52 to S56 are repeated. . As
a result, switching of the cartilage conduction vibration unit 1124 and the speaker 1013 and
switching of the display are automatically performed by bringing in / out the handle or by
contact / non-contact of the cartilage conduction vibration unit 1124. Further, in the state where
the cartilage conduction vibration unit 1124 is turned on, the switching of the presence or
absence of the self voice phase inversion signal addition based on the presence or absence of the
earplug bone conduction effect is automatically performed.
[0122]
10-05-2019
47
In the repetition of the above steps, the step of determining whether a predetermined time has
elapsed since the display on the display unit 205 first changed to the privacy protection display
in step S142 and the purpose of power saving when the predetermined time has elapsed The
step of turning off the display unit 205 itself may be inserted between step S142 and step S52.
At this time, a step of turning on the display unit 205 is inserted between step S148 and step S5
in response to this. Further, the flow of FIG. 23 can also be adopted in the eleventh embodiment
of FIG. 20 by omitting step S132.
[0123]
FIG. 24 is a perspective view showing Example 13 of the mobile phone according to the
embodiment of the present invention. FIG. 24A shows a state in which a transmission / reception
unit 1281 described later is integrated with the mobile phone 1201, and FIG. 24B shows a state
in which the transmission / reception unit 1281 is separated. In the mobile phone 1201 of the
thirteenth embodiment, the cartilage conduction vibration unit 1226 is disposed on the side
surface 1007 of the mobile phone 1201 in the state of FIG. 24 (A). This point is the same as the
eleventh and twelfth embodiments. In addition, Example 13 is based on an integral type without
movable parts as Examples 11 and 12 as a mobile phone, and is configured as a so-called
smartphone having a large screen 205 provided with a GUI function. It is done. And since there
are many points in common in the structure, the corresponding parts are assigned the same
reference numerals as in the twelfth embodiment, and the description will be omitted. In the
same manner as in Examples 11 and 12, in Example 13, "upper part" does not mean a separated
upper part, but means an upper part of an integral structure.
[0124]
Example 13 is the same as FIG. 22 (A) of Example 12 except that in the state of FIG. 24 (A), the
cartilage conduction vibration part 1226 and the transmitting part 1223 are arranged on the
right side as viewed in FIG. Is the same as However, when the display unit 205 is visible as
shown in FIG. 24, the cartilage conduction vibration unit 1126 is applied to the tragus of the left
ear. Then, in order to apply the cartilage conduction vibration unit 1126 to the tragus of the
right ear, the soft cartilage conduction vibration unit 1126 is made to face the left ear by
switching the mobile phone 1201 so as to face the back.
[0125]
10-05-2019

The thirteenth embodiment is different from the twelfth embodiment in that a transmitting /
receiving unit 1281 including a cartilage conduction vibration unit 1226 and a transmitting unit
1223 can be separated from a portable telephone 1201 as shown in FIG. 24B. The transmission /
reception unit 1281 can be attached and detached from the mobile phone 1201 by operating the
attachment / detachment lock button 1283. The transmission / reception unit 1281 further
includes a cartilage conduction vibration unit 1226 including a power supply unit, a control unit
1239 for the transmission unit 1223, and a transmission / reception operation unit 1209. The
handset unit 1281 is also. It has a short distance communication unit 1287 such as Bluetooth
(registered trademark) that can communicate wirelessly with the mobile phone 1201 and the
radio wave 1285 and contacts the user's voice picked up from the transmitter 1223 and the ear
of the cartilage conduction vibration unit 1226 The state information is transmitted to the mobile
phone 1201, and the cartilage conduction vibration unit 1226 is vibrated based on the voice
information received from the mobile phone 1201.
[0126]
The transmitting / receiving unit 1281 separated as described above functions as a pencil type
transmitting / receiving unit, and can freely communicate by holding the cartilage conduction
vibration unit 1226 freely and bringing it into contact with the tragus of the right or left ear is
there. In addition, the earplug bone conduction effect can also be obtained by increasing the
contact pressure to the tragus. Further, the transmission / reception unit 1281 in the separated
state can hear the sound by cartilage conduction, regardless of which side or tip of the cartilage
conduction vibration portion 1226 is placed around the long axis. Furthermore, the transmitting
/ receiving unit 1281 is normally housed in the mobile phone 1201 as shown in FIG. 24A and
appropriately separated as shown in FIG. 24B, as shown in FIG. 24B. In the separated state, for
example, the mobile phone 1201 is housed in the inner pocket or bag, and the transmission /
reception unit 1281 is inserted in the outer pocket of the chest like a pencil, and operations and
calls at the time of calling and receiving are transmitted / received Usage as performed only by
the unit 1281 is also possible. The cartilage conduction vibration unit 1226 can also function as
a vibrator for incoming calls.
[0127]
The pencil type transmission / reception unit 1281 as in the thirteenth embodiment is not
limited to the case where it is configured in combination with a dedicated mobile phone 1201
10-05-2019

having a storage unit. For example, it can be configured as an accessory of a general mobile
phone having a short distance communication function by Bluetooth (registered trademark) or
the like.
[0128]
FIG. 25 is a perspective view showing a fourteenth example of the mobile phone according to the
embodiment of the present invention. FIG. 25A shows a state in which a transmission / reception
unit 1381 to be described later is accommodated in the mobile phone 1201, and FIG. 25B shows
a state in which the transmission / reception unit 1281 is pulled out. The cellular phone 1301 of
the fourteenth embodiment is in a state where the cartilage conduction vibration unit 1326 is
disposed on the side surface 1007 of the cellular phone 1301 in the state of FIG. This point is the
same as the eleventh to thirteenth embodiments. In addition, the fourteenth embodiment is based
on an integrated type having no movable portion as in the eleventh to thirteenth embodiments as
a mobile phone, and is configured as a so-called smartphone having a large screen 205 provided
with a GUI function. It is done. And since there are many points in common in the structure, the
corresponding parts are assigned the same reference numerals as in the thirteenth embodiment,
and the description will be omitted. In the same manner as in Examples 11 to 13, in Example 14
as well, “upper part” does not mean the separated upper part, but means the upper part of the
integral structure.
[0129]
Example 14 also has the same configuration as that of FIG. 24 (A) of Example 13 in the state of
FIG. 25 (A). The fourteenth embodiment is different from the thirteenth embodiment in that the
transmitting / receiving unit 1381 communicates with the mobile phone 1301 not by wireless
but by wire as shown in FIG. 25 (B). The attachment / detachment of the transmission / reception
unit 1381 to / from the portable telephone 1301 is possible by operating the attachment /
detachment lock button 1283 in the same manner as in the thirteenth embodiment. In
transmission / reception unit 1381, cable 1339 is connected between cartilage conduction
vibration unit 1326 and transmission unit 1323 and between transmission unit 1323 and mobile
phone 1301. In the stored state shown in FIG. 25A, of the cable 1339, the portion between the
cartilage conduction vibration portion 1326 and the transmitting portion 1323 is stored in the
groove of the side surface 1007, and the transmitting portion 1323 and The portion between the
portable telephones 1301 is automatically taken up inside the portable telephone 1301 by a
spring when the transmitter 1323 is stored. The transmitter unit 1323 is provided with a remote
control operation unit for operations at the time of call origination and call reception. As
10-05-2019
50
described above, in the fourteenth embodiment, the voice of the user picked up from the
transmitter 1323 and the information on the contact state to the ear of the vibrator for cartilage
conduction 1326 are transmitted to the mobile phone 1301 by wire, and The cartilage
conduction vibration unit 1326 is vibrated based on the voice information received by wire from
the telephone 1301.
[0130]
The transmission / reception unit 1381 drawn as shown in FIG. 25B is used by being hooked to
the lower cartilage of the entrance of the ear canal such that the portion for the cartilage
conduction vibration unit 1326 touches the tragus. In this state, since the transmitter 1323 is
located near the mouth, the user's voice can be picked up. In addition, the earplug bone
conduction effect can also be obtained by raising the contact pressure on the tragus by holding
the portion for cartilage conduction vibration portion 1326. Furthermore, the transmitting /
receiving unit 1381 is normally stored as shown in FIG. 25 (A) and appropriately stored as
shown in FIG. 25 (B), and sent as shown in FIG. 25 (B). For example, the mobile phone 1301 can
be stored in an inner pocket or the like while the receiver unit 1381 is pulled out, and the
cartilage conduction vibration unit 1326 of the transmitter / receiver unit 1381 can be hooked
to the ear. The cartilage conduction vibration unit 1326 can also function as an incoming call
vibrator in the same manner as in the thirteenth embodiment.
[0131]
The transmission / reception unit 1381 of the wired earphone type as in the fourteenth
embodiment is not limited to the case where it is configured in combination with a dedicated
mobile phone 1301 having a storage unit. For example, it can be configured as an accessory of a
general mobile phone having an external earphone microphone connection terminal.
[0132]
The various features described in each of the above embodiments are not necessarily specific to
the particular embodiment, and the features of each embodiment may be modified as appropriate
with the features of the other embodiments as long as their advantages can be utilized. It is
possible to combine or rearrange.
[0133]
10-05-2019
51
In addition, the implementation of the various features shown in the above embodiments is not
limited to the above embodiments, and other embodiments can be implemented as long as the
advantages can be obtained.
For example, the arrangement of the cartilage conduction vibration portion on the side surface
with respect to the display surface in Example 11 to 14 facilitates contact with the tragus, by
transmitting voice information from the tragus by cartilage conduction. Since the point of
conduction of sound information can be used as a tragus, a sense of incongruent listening
posture similar to a conventional telephone that is heard with the ear is realized. Moreover, the
voice transmission by cartilage conduction is suitable for placement on the side because it is not
necessary to form a closed space in front of the canal as in the case of air conduction.
Furthermore, in order to conduct sound information by cartilage conduction, the proportion of
air conduction caused by the vibration of the vibrator is small, and even if the cartilage
conduction vibration part is disposed on the side of a narrow mobile phone, it is substantially
external. Sound can be transmitted into the user's ear canal without sound leakage. This is
because, in cartilage conduction, sound does not enter the ear canal as air conduction sound, but
sound energy is transmitted by contact with cartilage, and then sound is generated inside the ear
canal by vibration of the ear tissue It is from. Therefore, the adoption of the cartilage conduction
vibration part in the eleventh to fourteenth embodiments can be applied to the side surface to
the display surface without fear that the next person hears the receiving sound due to the sound
leakage to cause inconvenience or leakage of privacy. The effect is great also in arranging the
sound information output unit.
[0134]
However, from the viewpoint of enjoying the advantage of being able to prevent the
contamination of the display surface due to the contact of the ears and cheeks when listening to
the audio information, the arrangement on the side with respect to the display surface The
present invention is not limited to the case in which the cartilage conduction vibration unit. For
example, the audio information output unit may be an air conductive earphone, which may be
provided on the side surface to the display surface. Also, the voice information output unit is
configured as a bone in front of the ear (cheek arch) or a bone after the ear (milk projection) or a
bone conduction vibration unit applied to the forehead, and this is disposed on the side surface
to the display surface It is also good. Even in the case of these audio information output units, the
arrangement on the side surface with respect to the display surface prevents the display surface
from contacting the ear or cheek when listening to the audio information, so that it is possible to
10-05-2019
52
enjoy the advantage of being able to prevent the contamination. Also in these cases, when the
arrangement of the earphones and the bone conduction vibration unit is limited to one side, the
microphones can also be arranged on the side with respect to the display surface as in the
twelfth to fourteenth embodiments. Further, in the same manner as in the eleventh to the
fourteenth embodiments, when making a call by placing the earphone on the ear in the posture
as shown in FIG. 21, or making a call by placing the bone conduction vibration unit against the
bones before and after the ear. In the above, by making the display surface a privacy protection
display, it is possible to prevent the display including the privacy information from being seen by
other persons in front, rear, left or right.
[0135]
FIG. 26 is a system configuration diagram of a fifteenth embodiment according to an aspect of
the present invention. The fifteenth embodiment is configured as a transceiver unit for a mobile
phone, and forms a mobile phone system together with the mobile phone 1401. The fifteenth
embodiment has a system configuration common to the system configuration in a state in which
the transmission / reception unit 1281 is separated from the mobile phone 1201 as shown in
FIG. 24B in the thirteenth embodiment. The number is attached and the description is omitted
unless it is necessary. The mobile phone 1401 is not limited to a special configuration for use in
combination with a transmitting / receiving unit as in the mobile phone 1201 of the thirteenth
embodiment. It may be configured as a general mobile phone having a distance communication
function. In this case, the handset unit is configured as an accessory of such a general mobile
phone 1401 in the same manner as in the thirteenth embodiment. The details of these two cases
will be described later.
[0136]
Example 15 is different from Example 13 in that the transmitting / receiving unit is not a pencil
type as in Example 13, but is configured as a headset 1481. The transmission / reception unit
1481 has a cartilage conduction vibration unit 1426 and a transmission unit 1423 having a
piezoelectric bimorph or the like, and a control unit 1439 including a cartilage conduction
vibration unit 1426 and a power supply unit for the transmission unit 1423. The provision of the
transmission / reception operation unit 1409 conforms to the thirteenth embodiment.
Furthermore, the transmitting / receiving unit 1481 has a short distance communication unit
1487 such as Bluetooth (registered trademark) that can wirelessly communicate with the mobile
phone 1401 and the radio wave 1285, and the user's voice picked up from the transmitter 1423
and cartilage conduction The information on the contact state of the for-use vibration unit 1226
10-05-2019
53
with the ear is transmitted to the mobile phone 1201 and the vibration unit for cartilage
conduction 1426 is also vibrated based on the voice information received from the mobile phone
1401 according to the thirteenth embodiment.
[0137]
Next, the configuration unique to the fifteenth embodiment will be described. The headset 1481
is attached to the right ear 28 by the ear hooks 1489. The headset 1481 has a movable portion
1491 held by an elastic body 1473, and the cartilage conduction vibration portion 1426 is held
by the movable portion 1491. Then, in a state where the headset 1481 is attached to the right
ear 28 by the ear hooking portion 1489, the cartilage conduction vibration portion 1426 is
configured to contact the tragus 32. The elastic body 1473 enables the movable portion 1491 to
be bent in the direction of the tragus 32 and also functions as a shock absorbing material to the
cartilage conduction vibration portion 1426, from the mechanical impact applied to the headset
1481. The cartilage conduction vibration unit 1426 is protected.
[0138]
In the state of FIG. 26, listening of sound information by normal cartilage conduction becomes
possible, but when the sound information is difficult to hear due to environmental noise, this is
bent by pushing the movable part 1491 from the outside, and the cartilage conduction vibration
part By pressing 1426 more strongly to the tragus 32, the tragus 32 blocks the ear canal. As a
result, the earplug bone conduction effect described in the other embodiments is generated, and
the sound information can be transmitted with a louder sound. Further, by closing the ear hole
with the tragus 32, environmental noise can be shut off. Further, based on mechanical detection
of the bending state of the movable portion 1491, the phase of the information of one's own
voice picked up from the transmitting part 1423 is inverted and transmitted to the cartilage
conduction vibration part 1426 to cancel one's own voice. Since the utility and the like have been
described in the other embodiments, details are omitted.
[0139]
FIG. 27 is a system configuration diagram of a sixteenth embodiment according to an aspect of
the present invention. Similarly to the fifteenth embodiment, the sixteenth embodiment is also
configured as a headset 1581 constituting a transmitting and receiving unit for the mobile
10-05-2019
54
telephone 1401, and constitutes a mobile telephone system together with the mobile telephone
1401. The sixteenth embodiment has many points in common with the fifteenth embodiment, so
the common parts are denoted with the same reference numerals, and the description will be
omitted unless necessary. As described in the fifteenth embodiment, the mobile phone 1401 may
be either specially configured or configured as a general mobile phone. These two cases will be
described later.
[0140]
Example 16 is different from Example 15 in an elastic material (silicone-based rubber, a mixture
of silicone-based rubber and butadiene-based rubber, natural rubber, or the like) in which the
entire movable portion 1591 has an acoustic impedance similar to that of ear cartilage. It is made
by the structure which sealed the air bubbles. The cartilage conduction vibration unit 1526
having a piezoelectric bimorph or the like is embedded in the inside of the movable unit 1591 as
in the eighth embodiment. With such a configuration, the movable portion 1591 can be bent
toward the side of the tragus 32 including the cartilage conduction vibration portion 1526 by its
own elasticity. Although not shown for the sake of simplicity, circuit parts such as the cartilage
conduction vibration unit 1526 and the control unit 1439 are connected by the same connection
as the flexible connection 769 in FIG. 17C.
[0141]
In the sixteenth embodiment, the movable portion 1591 is in contact with the tragus 32 in the
state shown in FIG. 27, and sound information from the cartilage conduction vibration portion
1526 is transferred to the tragus 32 by cartilage conduction via the elastic material of the
movable portion 1591. Conducted. The utility of this configuration is similar to that described in
the fifth to tenth embodiments. Furthermore, when sound information is difficult to hear due to
environmental noise, the movable part 1591 is pushed from the outside to bend it and the
cartilage conduction vibration part 1526 is more strongly pressed to the tragus 32 to allow the
tragus 32 to be in the ear hole Try to close it. As a result, as in the fifteenth embodiment, the
earplug bone conduction effect is produced, and audio information can be transmitted with a
louder sound. Similar to the fifteenth embodiment, environmental noise can be blocked by
closing the ear hole with the tragus 32. Moreover, the phase of the information of one's own
voice picked up from transmitting part 1423 is reversed based on the mechanical detection of
the bending state of movable part 1591 and transmitted to vibration part 1526 for cartilage
conduction, so that one's own voice can be canceled. Same as Example 15.
10-05-2019
55
[0142]
Furthermore, in the sixteenth embodiment, since the cartilage conduction vibration part 1526 is
embedded inside the movable part 1591, the elastic material constituting the movable part 1591
is the cartilage conduction vibration part from the mechanical impact applied to the headset
1581. It functions as a cushioning material that protects the 1426 and also protects the cartilage
conduction vibration unit 1426 from mechanical impact on the movable unit 1691 itself.
[0143]
FIG. 28 is a block diagram of a sixteenth embodiment, and the same reference numerals as in FIG.
27 denote the same parts in FIG.
Further, since the configuration of the block diagram has many parts in common with the fourth
embodiment, the corresponding parts are assigned the same reference numerals as those parts.
The description of the same or common parts will be omitted unless necessary. In the sixteenth
embodiment, the reception processing unit 212 and the earphone 213 in FIG. 28 correspond to
the reception unit 13 in FIG. 27, and the transmission processing unit 222 and the microphone
223 in FIG. 28 correspond to the transmission unit 23 in FIG. Equivalent to. As in the fourth
embodiment, the transmission processing unit 222 transmits part of the operator's voice picked
up from the microphone 223 to the reception processing unit 212 as a side tone, and the
reception processing unit 212 receives the information from the telephone communication unit
47. By superimposing the operator's own side tone on the voice of the other party and outputting
the result to the earphone 213, the balance between bone conduction and air conduction of one's
own voice in a state in which the mobile phone 1401 is placed on the ear is made natural. Get
close.
[0144]
The block diagram of the embodiment 16 in FIG. 28 differs from the block diagram of the
embodiment 4 in FIG. 8 in that the cellular phone 301 of the fourth embodiment in FIG. The
headset 1581 is divided into two. That is, FIG. 28 corresponds to a block diagram in the case
where the mobile phone 1401 is specially configured to be used in combination with the headset
1581 in the sixteenth embodiment.
10-05-2019

[0145]
Specifically, in FIG. 28, the output of the phase adjustment mixer unit 236 is wirelessly
transmitted to the outside by the short distance communication unit 1446 such as Bluetooth
(registered trademark). The short distance communication unit 1446 also inputs an audio signal
wirelessly received from the external microphone to the transmission processing unit.
Furthermore, although illustration and description were abbreviate | omitted in the other
Example, in FIG. 28, the power supply part 1448 which has a storage battery electrically fed to
the whole mobile telephone 1401 is shown in figure.
[0146]
On the other hand, the configuration of the headset 1581 includes a short distance
communication unit 1487 communicating with the short distance communication unit 1446 of
the mobile phone 1401 and the radio wave 1285 and a power supply unit 1548 for supplying
power to the entire headset 1581. The power supply unit 1548 supplies power by a replaceable
battery or a built-in storage battery. Further, the control unit 1439 of the headset 1581 causes
the short distance communication unit 1487 to wirelessly transmit the voice picked up by the
microphone 1423 to the mobile phone 1401, and the cartilage conduction vibration unit based
on the voice information received by the short distance communication unit 1487. The drive
control of 1526 is performed. Further, control unit 1439 transmits an incoming call reception
operation or a calling operation from operation unit 1409 from short range communication unit
1487 to mobile phone 1401. The bending detection unit 1588 mechanically detects the bending
state of the movable unit 1591, and the control unit 1439 transmits the bending detection
information from the short distance communication unit 1487 to the mobile phone 1401. The
bending detection unit 1588 can be configured by, for example, a switch that is mechanically
turned on when reaching a predetermined bending angle or more. The control unit 239 of the
mobile phone 1401 controls the phase adjustment mixer unit 236 based on the bending
detection information received by the short distance communication unit 1446, and phase
inversion based on the voice transmitted from the microphone 1423 to the voice transmission
processing unit 222. It is determined whether to add the signal of the part 240 to the voice
information from the reception processing part 212 or not.
[0147]
FIG. 29 is a block diagram of the sixteenth embodiment of FIG. 27 in which the mobile phone
10-05-2019
57
1401 is configured as a general mobile phone and the headset 1581 is configured as an
accessory thereof, in order to avoid confusion with FIG. A seventeenth embodiment will be
described. Since many configurations in FIG. 29 are common to those in FIG. 28, the same
reference numerals as in FIG. 28 denote the same parts, and a description thereof will be omitted
unless necessary.
[0148]
As described above, in the seventeenth embodiment shown in FIG. 29, the mobile phone 1601 is
configured as a general mobile phone having a near field communication function by Bluetooth
(registered trademark) or the like. Specifically, the short distance communication unit 1446
inputs voice information from an external microphone similar to that input from the microphone
223 to the transmission processing unit 222 and voice information similar to output to the
earphone 213 Output to the outside. The switching between the voice information input to and
output from the outside through the short range communication unit 1446 and the microphone
223 and the earphone 213 inside is performed by the control unit 239. As described above, in
the seventeenth embodiment of FIG. 29, the functions of the sound quality adjustment unit 238,
the phase inversion unit 240, and the phase adjustment mixer unit 236 in the sixteenth
embodiment of FIG. 28 are transferred to the headset 1681 side.
[0149]
Corresponding to the above, the configuration of the headset 1681 in the seventeenth
embodiment of FIG. 29 is different from that of the sixteenth embodiment in FIG. 28 in the
following points. Although receiving voice information received by the short distance
communication unit 1487 is input to the phase adjustment mixer unit 1636 under the control of
the control unit 1639 of the headset 1681, further voice information from the phase inverting
unit 1640 can also be input. Configured Then, the phase adjustment mixer unit 1636 mixes the
received voice information from the phase inversion unit 1640 with the received voice
information to drive the cartilage conduction vibration unit 1626 as necessary. More specifically,
part of the operator's voice picked up from the microphone 1423 is input to the sound quality
adjustment unit 1638, and the sound quality of his own voice to be transmitted to the cochlea
from the cartilage conduction vibration unit 1628 is generated when the earplug bone
conduction effect occurs. It adjusts to the tone quality similar to the operator's own voice
transmitted to the cochlea by internal conduction from the vocal cords, and makes cancellation
of both effective. Then, the phase inverting unit 1640 phase-inverts the voice whose sound
quality has been adjusted in this way, and outputs the result to the phase adjustment mixer unit
10-05-2019
58
1636 as necessary.
[0150]
In the phase control mixer unit 1636, the bending angle of the movable portion 1591 detected
by the bending detecting unit 1588 reaches a predetermined value or more, and the phase
adjustment mixer unit 1636 corresponds to a state in which the earlobe is blocked by the tragus
To do this, the cartilage conduction vibration unit 228 is driven by mixing the output from the
phase inversion unit 1640 according to an instruction from the control unit 1639. By this, the
excessive one's own voice during earplug bone conduction effect generation is canceled, and a
sense of discomfort is alleviated. At this time, the degree of cancellation is adjusted so that the
voices corresponding to the side tones are left without being canceled. On the other hand, when
the bending detection unit does not detect bending of a predetermined level or more, the phase
adjustment mixer unit corresponds to a state in which the ear hole is not blocked by the tragus
and the ear plug bone conduction effect is not generated. The mixing of the voice-inverted phase
inversion output from the phase inversion unit 1640 is not performed based on the instruction of
As in the fourth embodiment, in the seventeenth embodiment shown in FIG. 29, the positions of
the sound quality adjustment unit 1638 and the phase inversion unit 1640 may be reversed.
Furthermore, the sound quality adjustment unit 1638 and the phase inversion unit 1640 may be
integrated as a function in the phase adjustment mixer unit 1636. Note that the control unit
1639 transmits the incoming call reception operation or the calling operation by the operation
unit 1409 from the short distance communication unit 1487 to the mobile phone 1401 in the
same manner as in the sixteenth embodiment.
[0151]
The block diagrams of FIGS. 28 and 29 can be applied not only to the configuration of the system
diagram of FIG. 27 but also to the system diagram of the fifteenth embodiment of FIG. Further, if
the bending detection unit 1588 is replaced with the pressure sensor 242 as shown in FIG. 8, the
embodiment can be applied to the embodiment 13 of FIG. 24 or the embodiment 14 of FIG.
However, in the case where it is read as in the thirteenth embodiment, as shown in FIG. 24A,
when the transmitting / receiving unit 1281 is incorporated into the portable telephone 1201,
contact points for directly connecting both are provided in the portable telephone 1201 and the
transmitting / receiving unit 1281 . In the state of FIG. 24A, wireless communication between the
mobile phone 1201 and the transmission / reception unit 1281 by the short distance
communication unit is automatically switched to communication via such a contact unit. Also, in
the case of reading in the fourteenth embodiment, in place of the short distance communication
10-05-2019
59
unit, a connector race contact for connecting both by wire is provided in the portable telephone
1301 and the transmission / reception unit 1381.
[0152]
FIG. 30 is a flowchart of the operation of the control unit 1639 of the headset 1681 in the
seventeenth embodiment of FIG. The flow in FIG. 30 starts with turning on of the main power
supply by the operation unit 1409, and performs initial rise and function check of each unit in
step S162. Next, in step S164, the near field communication connection with the mobile phone
1601 is instructed, and the process proceeds to step S166. When the short distance
communication is established based on the instruction in step S164, the headset 1681 is
continuously connected to the mobile phone 1601 unless the main power is turned off
thereafter. In step S166, it is checked whether the short distance communication with the mobile
phone 1601 has been established, and if the establishment is confirmed, the process proceeds to
step S168.
[0153]
In step S168, it is checked whether the incoming signal from the mobile phone 1601 has been
transmitted through near field communication. Then, if there is an incoming call, the process
proceeds to step S170, and the cartilage conduction vibration unit 1626 is driven to vibrate at
the incoming call. This incoming vibration may be a frequency in the audible range, or may be a
low frequency vibration with a large amplitude that allows the tragus 32 to feel vibration. Next,
in step S172, it is checked whether the incoming call signal has been stopped due to a call
termination operation or the like on the side which made a call, and if there is no stop, step S174
follows and it is checked whether there is a reception operation by the operation unit 1409. If
there is a receiving operation, the process proceeds to step S174. On the other hand, if there is
no reception operation in step S174, the flow returns to step S170, and the loop from step S170
to step S174 is repeated unless the incoming vibration of the cartilage conduction vibration unit
1626 is stopped or reception operation is performed. .
[0154]
On the other hand, when the incoming signal is not detected in step S168, the process proceeds
to step S178, and it is checked by the operation unit 1409 whether or not the call destination
10-05-2019
60
operation with one touch to the registered callee has been performed. Then, when a calling
operation is detected, the process proceeds to step S180, where the calling operation is
transmitted to the mobile phone 1601 to make a call, and a response from the other party
responds to the signal indicating that the telephone connection is established. Check if it has
been transmitted from Then, when establishment of the telephone connection is confirmed in
step S180, the process proceeds to step S176.
[0155]
In step S176, the cartilage conduction vibration unit 1626 is turned on to receive voice
information, and in step S182, the microphone 1423 is turned on for transmission, and the
process proceeds to step S184. In step S184, it is checked whether bending of the movable part
1591 or more at a predetermined angle or more is detected. Then, when bending is detected, the
process proceeds to step S186, and a phase inversion signal of one's own voice is added to the
cartilage conduction vibration unit 1626, and the process proceeds to step S188. On the other
hand, when bending at a predetermined angle or more is not detected in step S184, the process
proceeds to step S190, and addition of the phase inversion signal of one's own voice to the
cartilage conduction vibration unit 1626 is eliminated, and the process proceeds to step S188. In
step S188, it is checked whether or not a signal indicating that the call state has been cut off or
not received from the mobile phone 1601 and if the call is not cut back, the process returns to
step S176 and a call cut is detected in step S188 below. Steps S176 to S188 are repeated. This
corresponds to the occurrence and disappearance of the earplug bone conduction effect based
on the bending of the movable part 1591 during a call.
[0156]
On the other hand, when it is detected that the call disconnection signal is received from the
mobile phone 1601 in step S188, the process proceeds to step S192 to turn off the reception by
the cartilage conduction vibration unit 1626 and turn off the transmission by the microphone
1423 Transfer to S194. In step S194, it is checked whether the no-call state continues for a
predetermined time or more, and if so, the process proceeds to step S196. In step S 196,
transition to the power saving standby state such as dropping the clock frequency to the lowest
level necessary to maintain the standby state of the short distance communication unit 1487 is
made, and incoming signal reception from the mobile phone 1487 or emission of the operation
unit 1409 is performed. In response to the call operation, processing is performed to enable an
interrupt for returning the near field communication unit 1487 to the normal communication
state. Then, after such processing, the process proceeds to step S198. On the other hand, when a
10-05-2019
61
no-call state for a predetermined time or more is not detected in step S194, the process directly
proceeds to step S198. If the establishment of the short distance communication can not be
confirmed in step S166, or if the calling operation is not detected in step S178, or if the
establishment of the telephone connection can not be confirmed in step S180, the process
directly proceeds to step S198.
[0157]
In step S198, it is checked whether the main power is turned off by the operation unit 1409, and
the flow is ended if the main power off is detected. On the other hand, if the main power off is
not detected, the flow returns to step S166, and steps S166 to S198 are repeated to cope with
various state changes of the headset 1681 unless the main power is turned off.
[0158]
The flow of FIG. 30 is applicable not only to the configuration of the system diagram of FIG. 27
but also to the system diagram of the fifteenth embodiment of FIG. In addition, if “bending
detection” in step S184 is replaced with “detection of occurrence of“ ear plug bone
conduction ”” as in step S52 in FIG. 10, this also applies to example 13 in FIG. 24 or example
14 in FIG. It is applicable.
[0159]
FIG. 31 is a flowchart of the control unit of the headset configured to perform software detection
in place of mechanical detection of bending detection in the seventeenth embodiment of FIG. 30,
which is a confusion with FIG. 30. This will be described as Example 18 to avoid. Further, in FIG.
31, the same steps as those in FIG. 30 carry the same step numbers, and the explanation thereof
will be omitted unless necessary. Then, different portions in FIG. 31 are shown by bold frames
and bold faces, and these portions will be mainly described. Specifically, in Example 18, assuming
that the cartilage conduction vibration unit 1626 is a piezoelectric bimorph element, a signal
connecting the phase adjustment mixer unit 1636 and the cartilage conduction vibration unit
1626 according to the fourth embodiment in FIG. It is configured to monitor a signal appearing
in the line and detect a signal change appearing in the cartilage conduction vibration unit
(piezoelectric bimorph element) 1526 by a strain based on an operation impact at the moment of
bending of the movable unit 1591 or a return from the bending. The bending state is detected by
10-05-2019
62
processing the signal change in a soft manner.
[0160]
31 will be described based on the above premise. First, step S200 collectively shows steps S170
to S174, step S178 and step S180 of FIG. It is the same thing. When the telephone connection is
established based on the reception operation for the incoming call or the response of the other
party to the call, the process proceeds to step S176, and if there is no telephone connection, the
process proceeds to step S198.
[0161]
Steps S202 to S210 are steps relating to the detection of bending, and when the step S182 to the
step S202, first appear at the input terminal of the cartilage transmission vibration unit 1626 (a
signal line connecting the phase adjustment mixer unit 1636 and the cartilage conduction
vibration unit 1626). Sample the signal Then, in step S204, the cartilage conduction unit drive
output from the control unit 1639 to the phase adjustment mixer unit 1636 is sampled at the
same timing at the same timing. Next, in step S206, the difference between these sampling values
is calculated, and it is detected whether the difference calculated in step S208 is greater than or
equal to a predetermined value. This function corresponds to the function of the pressure sensor
242 in FIG. 9, but the pressure sensor of FIG. 9 continuously detects the pressing state, whereas
the system of FIG. 27 detects the moment of bending or return from bending. Capturing changes
in bending state by operation impact.
[0162]
If it is detected in step S208 that a difference greater than or equal to a predetermined value is
generated between both sampling values, the process proceeds to step S210. At the stage of step
S208, it is not known whether the difference between the two sampled values is greater than a
predetermined value due to bending or return from bending. However, in step S210, after the
cartilage transmission vibration unit 1626 is turned on in step S176, it is checked whether the
occurrence of the difference is an odd number based on the occurrence history of the difference.
And if it is the odd-numbered time, while it transfers to step S186, if it is the even-numbered
time, it will transfer to step S190. Since the return from the bending or the bending of the
movable portion 1691 always occurs alternately, it is switched whether or not the self voice
10-05-2019
63
phase inversion signal is added each time there is an operation shock as described above. If the
difference count is reversed due to a malfunction, the operation history of the difference can be
reset by the operation unit 1409.
[0163]
Step S212 is a diagram collectively showing steps S194 and S196 of FIG. 30, and the contents
are the same. As described above, in the eighteenth embodiment, as in the fourth embodiment
and the like, the bending detection of the movable portion 1591 is performed using the sensor
function of the cartilage conduction vibration unit 1626 itself, whereby the earplug bone
conduction effect can be obtained. The occurrence status has been determined. The flow of FIG.
31 is applicable not only to the configuration of the system diagram of FIG. 27 but also to the
system diagram of the fifteenth embodiment of FIG. In addition, even when the cartilage

viewing glasses 2381 and the ear hook 2300 of the temple of the ordinary glasses is achieved,
and the contact area of the right temple 2382 and the ear hook 2300 due to the elasticity of the
contact 2363 It prevents that it shakes by vibration. Then, in the state of FIG. 39A, the vibration
of the right ear cartilage conduction vibration unit 2324 is transmitted to the outer side 1828 of
the cartilage of the base of the right ear in direct contact via the contact portion 2363 and The
eyeglasses are transmitted to the ear hooks 2300 of the right temple of the glasses and
transmitted indirectly to the outside 1828 of the cartilage at the base of the ear via the ear hooks
2300.
[0188]
On the other hand, when a person with naked eyes wears the viewing glasses 2381 directly, the
entire contact portion 2363 directly contacts the outside 1828 of the cartilage at the base of the
right ear, and transmits the vibration of the cartilage conduction vibration portion 2324 for the
right ear. Do. Since the outer side of the contact portion 2363 is chamfered, even in this case, the
right temple portion 2382 can be hung on the ear without a sense of discomfort.
[0189]
Next, in the modification shown in FIG. 39B, as is apparent from the cross-sectional view, a
contact portion 2363 is provided in the same manner as in FIG. 39A in the portion hooked to the
10-05-2019
74
lower ear of the right temple 2360. It is done. Then, in the same manner as in FIG. 39A, the
contact portion 2363 is made of an elastic body having acoustic impedance similar to that of the
ear cartilage, and the cartilage conduction vibration portion 2324 for the right ear is encased in
it. It is held. As apparent in FIG. 39 (B). In a modification, the cross-sectional shape of the contact
portion 2363 is different, and a concave slope is provided instead of the groove, whereby the
right temple 2360 of the viewing glasses 2381 can be used as an ear outside the ear hooks 2300
of the glasses. As it is hooked, reliable contact between the two is achieved, and the elasticity of
the contact portion 2363 prevents the contact portion of the right hook portion 2360 and the
ear hook portion 2300 from being flapped by vibration. Then, in the state of FIG. 39 (B), the
vibration of the right ear cartilage conduction vibration unit 2324 is transmitted to the outside
1828 of the cartilage of the base of the right ear that is in direct contact via the contact portion
2363. The eyeglasses are transmitted to the ear hooks 2300 of the right temple of the glasses
and transmitted indirectly to the outside 1828 of the cartilage at the base of the ear via the ear
hooks 2300.
[0190]
On the other hand, when a person with naked eyes wears the viewing glasses 2381 directly, the
entire contact portion 2363 directly contacts the outside 1828 of the cartilage at the base of the
right ear, and transmits the vibration of the cartilage conduction vibration portion 2324 for the
right ear. Do. The outer side of the contact portion 2363 is chamfered even in the case of the
modification of FIG. 39B, and even when the viewing glasses 2381 are directly worn, the right
temple 2360 can be hung on the ear without a sense of discomfort. As is clear from FIG. 39 (B),
in cartilage conduction, contact with the ear cartilage below or outside the temples of the glasses
is important, not the facial bone inside the temples of the glasses, and the shape of the contact
portion Is determined for this purpose.
[0191]
As described above, in the twentieth through twenty-fifth embodiments, the vibration of the
cartilage conduction vibration unit 2324 is transmitted to the outside of the cartilage at the base
of the ear, and this is generated from the inner wall of the external ear canal by vibrating the
cartilage around the canal of the ear canal The sound conduction is transmitted to the tympanic
membrane, and a part of cartilage conduction is directly transmitted to the right inner ear
through the cartilage. Therefore, good conduction can be obtained by contact with the outer side
of the ear cartilage simply by wearing the glasses in a normal state. On the other hand, in the
case of the conventional bone conduction, it is necessary to hold the bone in front of or behind
10-05-2019
75
the ear tightly with the inner part of the temple of the glasses, which is accompanied by pain and
can not withstand long time use. In the present invention, there is no such problem, and it is
possible to listen to audio information comfortably with the same feeling of use as normal
glasses.
[0192]
The various features of each of the embodiments described above are not limited to the
individual embodiments, and can be replaced or combined with the features of the other
embodiments as appropriate. For example, in the description of the twenty-first embodiment in
FIG. 34, a dummy cover is put on the ear hooking portion of the other temple, but a pair of the
configuration of FIG. 34 is prepared and covered on the ear hooking portions of the left and right
temples. If so, it becomes possible to listen to a stereo audio signal as in the twenty-fifth
embodiment of FIG. At this time, it is possible to connect both by wireless communication, but it
is also possible to connect by a glass cord combined cable as in the embodiment 22 of FIG. With
regard to the characteristics of the glass cord, the structure of FIG. 34 and the dummy cover in
Example 21 may be connected by a glass cord to prevent loss. In addition, regarding the feature
of the above-mentioned stereo formation, the twenty-third embodiment of FIG. 36 does not
distribute the constituent elements to the left and right temples in the same manner as above but
prepares two sets of necessary constituent elements and positions on the left and right temple
parts. If this is done, it becomes possible not only to make the image 3D but also to listen to a
stereo audio signal as in the twenty-fifth embodiment of FIG. At this time, referring to the twentyfifth embodiment, part of the left and right configurations (for example, at least the control unit
and the power supply) can be appropriately shared.
[0193]
In the above embodiments, the utility of the present invention is described taking the example of
a mobile phone and its transceiving unit, or 3D television viewing glasses, but the advantages of
the present invention are not limited to this and it is also possible in other implementations. It
can be used. For example, the various features of the invention described above are also valid in a
hearing aid implementation.
[0194]
10-05-2019
76
The various features of each of the embodiments described above are not limited to the
individual embodiments, but can be implemented in various embodiments as long as the
advantages of the features can be obtained. For example, FIG. 40 is a perspective view showing a
modification of the tenth embodiment in FIG. Also in this modification, as in FIG. 19, the cartilage
conduction vibration source 925 including a piezoelectric bimorph element or the like serves as
a cartilage conduction vibration source and also serves as a driving source of a receiver for
generating a sound wave transmitted to the tympanic membrane by air conduction. . However, in
the modification of FIG. 40, the cartilage conduction vibration source 925 itself extends to the
side of the mobile phone 901, and vibrates the right end 224 and the left end 226. Therefore, in
the same manner as in FIG. 19, the sound can be heard in cartilage conduction by bringing either
of them into contact with the tragus. In addition, the cartilage conduction vibration source 925
vibrates not only at the right end 224 and the left end 226 but on the whole. Therefore, as in the
case of FIG. 19, audio information can be transmitted regardless of where on the inner upper end
side of the mobile phone 901 is in contact with the ear cartilage. A cartilage conduction output
portion 963 made of a material having an acoustic impedance similar to that of the ear cartilage
is disposed in front of the cartilage conduction vibration source 925, as in FIG.
[0195]
In addition, the following modification is possible for Embodiment 23 of FIG. That is, in the
twenty-third embodiment, the transmitting unit 1723 is configured by a normal air guiding
microphone, but instead of this, if the transmitting unit 1723 is configured by a bone conductive
microphone (a bone conduction contact type microphone or pickup) It is possible to selectively
pick up the speaker's voice without picking up the noise under noise. Furthermore, it is also
possible to send voice with a low voice that does not bother the surroundings. The temples of the
glasses are generally in contact naturally with the bone in front of the ear (the zygomatic arch or
a part of the temporal bone above the zygomatic arch) or the bone after the ear (temporal bone
mastoid). Therefore, referring to FIG. 36, by disposing the transmitting portion 1723 configured
by the bone conduction contact type microphone at the above-described contact portion with the
bone in the right temple portion 2184 of the glasses, it is possible to transmit the bone by
conduction. It is possible to pick up the voice of the person. Further, as shown in FIG. 36, the
vibration from the cartilage conduction vibration unit 1826 is bone conduction by distributing
the transmission unit 1723 including the cartilage conduction vibration unit 1826 and the bone
conduction contact type microphone to the left and right temples. It can prevent the contact type
microphone from picking up.
[0196]
In the twenty-third embodiment of FIG. 36 or the modification as described above, it is possible
10-05-2019
77
to omit the configuration related to 3D display from the lens portion 2186 and to provide a
normal glasses configuration in which only the right lens 2110 and the left lens 2114 are
included. is there.
[0197]
On the other hand, the following modification is possible also for the twenty-fifth embodiment of
FIG.
That is, since the twenty-fifth embodiment is configured as a viewing glasses 2381, the sound
source of stereo audio information is in the 3D television 2301, and based on the audio signal
received by the infrared communication unit 2387, the cartilage conduction vibration unit 2324
for the right ear and the left The ear cartilage conduction vibration unit 2326 is vibrated.
However, instead of this, a stereo audio signal unit serving as a sound source unit of stereo audio
information and an audio memory for providing data to the stereo audio signal unit are either the
glasses main unit 2386 or the right temple 2382 and the left temple 2384 in FIG. The present
invention can be configured as an independent portable music player if it is distributed and
incorporated. In order to understand the configuration of such a modification with reference to
FIG. 38, the above-described stereo audio signal unit and an audio memory for providing data
thereto are included in the control unit 2339. In the case of this modification, cooperation with
the 3D television 2301 is unnecessary, so in FIG. 38 the glasses main part 2386 is replaced with
the right shutter 2358, the left shutter 2359 and the shutter drive part 2357 in Embodiment 23
of FIG. Such as placing the right lens and left lens of normal glasses.
[0198]
In addition, in the case of the modified example in which the main lens 2386 is made up of the
right lens and the left lens as described above and the normal glasses are used, the control unit,
the audio drive unit, the external communication unit, the power supply unit, etc. As to each
component disposed in the main portion 2386, as in the twenty-third embodiment shown in FIG.
36, the glasses main portion 2386 can be prevented from being enlarged by distributing them to
the right temple and the left temple as appropriate. You may The infrared communication unit
2387 in the modification has a function of inputting sound source data from an external sound
source data holding device such as a personal computer. The infrared communication unit 2387
also adjusts the volume by the right ear cartilage conduction vibration unit 2324 and the left ear
cartilage conduction vibration unit 2326 by remote control at hand, or adjusts the balance of left
10-05-2019
78
and right vibration output. Can function as a wireless communication unit. Furthermore, when
the portable music player cooperates with the mobile phone, it can also receive audio
information of the mobile phone. In this case, if the portable music player is provided with an air
conduction microphone or a bone conduction microphone, the portable music player can also
function as an external transmission / reception device of the mobile phone.
[0199]
The above-mentioned device of arrangement of the component to the glasses main part 2386
and the right temple 2382 and the left temple 2384 is not limited to the above modification. For
example, even in the case of the viewing glasses 2381 itself in the twenty-fifth embodiment of
FIG. 38, the control unit 2339, the infrared communication unit 2387, the power supply unit
2348, the right audio drive unit 2335 and the left audio drive unit It may be distributed to the
left temple 2384 as appropriate.
[0200]
FIG. 41 is a perspective view of a twenty-sixth embodiment according to an aspect of the present
invention, which is configured as a mobile phone. Similar to the modification of the tenth
embodiment shown in FIG. 40, the mobile telephone 2401 of the twenty-sixth embodiment is an
integral type having no movable part, and is configured as a so-called smartphone having a large
screen 205 having a GUI function. ing. And since there are many points in common in the
structure, corresponding parts are assigned the same reference numerals as in FIG. In the same
manner as in Example 10 and its modification, in Example 26, "upper part" does not mean the
separated upper part, but means the upper part of the integral structure.
[0201]
The difference of the twenty-sixth embodiment from the modification of the tenth embodiment
shown in FIG. 40 is that the vibration of the cartilage conduction vibration source 925 is also
used as a vibration source for producing a feedback feeling of touch operation in the touch panel
function of the large screen display unit 205. It is a point. Specifically, a vinyl-based or urethanebased vibration isolation material 2465 is provided between the cartilage conduction vibration
source 925 and the configuration (screen display unit 205) located below the cartilage
conduction vibration source 925. It is configured not to easily transmit an audio signal due to
10-05-2019
79
cartilage conduction to the screen display unit 205 or the like due to a difference or the like. On
the other hand, when any input by the touch panel function is received by touching the large
screen display unit 205, the cartilage conduction vibration source 925 vibrates at a low
frequency lower than the audible range to feed it back to the touched finger. It is done. Then,
since the frequency at which the vibration frequency substantially matches the resonance
frequency of the vibration isolation material 2465 is selected, the vibration isolation material
2465 resonates by the vibration of the cartilage conduction vibration source 925 and this is
transmitted to the screen display unit 205 . Thus, the vibration isolation material 2465 that
prevents vibration in the sound area functions as a vibration transmission material for low
frequency vibration for feedback. As a result, low frequency vibration is transmitted to the finger
touching the large screen display unit 205, and it can be known that the touch input has been
accepted. In order to prevent confusion between the impact of the touch operation itself and the
feedback vibration responsive thereto, the cartilage conduction vibration source 925 provides a
predetermined delay from the moment of touch, and feedback vibration is caused after the touch
shock is settled.
[0202]
In the twenty-sixth embodiment, the operation button 2461 is provided, and used for an
operation of turning on / off the touch panel function of the large screen display unit 205 or the
like. In addition, although the cartilage conduction output portion 963 provided in the
modification of the tenth embodiment shown in FIG. 40 is omitted for simplification of the
illustration in the twenty-sixth embodiment, providing this is optional. .
[0203]
FIG. 42 is a block diagram of the twenty-sixth embodiment, and the same reference numerals as
in FIG. 41 denote the same parts, and a description thereof will be omitted. Further, the
configuration of the block diagram of FIG. 42 has many points in common with the block
diagram of the fourth embodiment in FIG. 8 and the configuration of the main part conceptual
block diagram in FIG. The same reference numerals will be assigned to the configuration of and
the description will be omitted.
[0204]
10-05-2019
80
The large screen display unit 205 in FIG. 42 illustrates a touch panel driver 2470 which is
controlled by the touch panel 2465 and the control unit 2439 to drive the touch panel 2465, but
this is not unique to the twenty-sixth embodiment. The large screen display unit 205 is common
to the other embodiments having the touch panel function, and in the other embodiments, the
illustration is omitted to avoid complication. In FIG. 42, the vibration isolation material 2465 is
illustrated in the portion of the cartilage conduction vibration source 925 and the touch panel
2468, but this is only for convenience of the illustrated space of the block diagram. The vibration
isolation material 2465 is the same and does not mean that it is separated and provided at the
position of the cartilage conduction vibration source 925 and the touch panel 2468, respectively.
That is, what is shown in FIG. 42 is that the vibration isolation material 2465 resonates by the
low frequency vibration of the cartilage conduction vibration source 925, and this is transmitted
to the touch panel 2468.
[0205]
As shown in FIG. 42, in the twenty-sixth embodiment, the low frequency source 2466 for
generating a drive signal having a frequency substantially matching the resonance frequency of
the vibration isolation material 2465 is provided, and the control unit 2439 is a touch panel
driver 2470. When it receives an input by sensing a finger touch, it instructs a low frequency
output from the low frequency source 2466 through a predetermined delay. The phase
adjustment mixer unit 2436 drives the cartilage conduction vibration source 925 based on the
signal from the telephone function unit 45 in the call state, but blocks the signal from the
telephone function unit 45 in the non-call operation state where the touch panel is operated.
Instead, the cartilage conduction vibration source 925 is driven based on the signal from the low
frequency source 2466. In the call state, the phase adjustment mixer unit 2436 blocks the signal
from the low frequency source 2466.
[0206]
The function of the control unit 2439 of FIG. 42 in the twenty-sixth embodiment can use the
flowchart of the fourth embodiment in FIG. The combination of the cartilage conduction vibration
source 925 with the touch operation feedback touch vibration source, which is a feature of the
twenty-sixth embodiment, can be understood as a detailed function of step S42 in FIG.
[0207]
10-05-2019
81
FIG. 43 shows the details of step S42 of FIG. 10 as described above. When the flow starts, it is
first checked in step S222 whether a non-call operation has been performed. This step is the
same as step S6 in the first embodiment of FIG. 4, and checks the presence or absence of non-call
operations such as mail operations, Internet operations, other settings, and operations that do
not use radio waves such as downloaded games. It is Then, if these operations are performed, the
process proceeds to step S224, and it is checked whether the touch panel is insensitive. If not in
the insensitive state, the cartilage conduction vibration unit is turned on in step S226. On the
other hand, when it is detected in step S224 that the touch panel is insensitive, it means that the
non-call operation was performed by the operation button 2461. Therefore, the process proceeds
to step S228, and button setting processing corresponding to the operation is performed. I do.
Next, in step S230, it is checked whether or not the touch panel has been enabled by button
operation, and if so, the process proceeds to step S226. It should be noted that the flow is
immediately ended if the non-call operation is not detected in step S222 or if the valid setting of
the touch panel is not detected in step S230.
[0208]
When the cartilage conduction vibration unit is turned on in step S226, the flow proceeds to step
S232, controls the phase adjustment mixer unit to cut off the output from the telephone function
unit 45, and the output of the low frequency reduction 2466 is cartilage conduction vibration in
step S234. It connects to the source 925 and reaches step S236. In step 236, the presence or
absence of the touch panel operation is checked. If there is an operation, the process proceeds to
step S238 to perform response processing according to the operation. Then, the process
proceeds to step 240 to set a predetermined delay time (for example, 0.1 second), and the
process proceeds to step 242. In step S242, a low frequency is output from the low frequency
source 2466 for a predetermined time (for example, 0.5 seconds), the operation feeling is fed
back to the operated finger, and the process proceeds to step S244.
[0209]
In step S244, it is checked whether or not the touch panel has been in the non-operation state for
a predetermined time (for example, 3 seconds) after the last touch panel operation, and if it does
not correspond, the process returns to step S236. Thereafter, as long as the operation of the
touch panel continues within a predetermined time, steps S236 to S244 are repeated, and the
operation touch feedback by the touch panel input and the cartilage conduction vibration source
925 is continued.
10-05-2019
82
[0210]
On the other hand, when it is detected in step S244 that the touch panel has been in the nonoperation state for a predetermined time or more, the process proceeds to step S246 to turn off
the cartilage conduction vibration unit, and further controls the phase adjustment mixer unit in
step S248. The output from the function unit 45 is connected to the cartilage conduction
vibration source 925, and the output of the low frequency reduction 2466 is cut off in step S250,
and the flow is ended for the time being. Thereafter, the flow is executed according to FIG. 10,
and if the call is not detected in step S44 of FIG. 10, the process immediately proceeds to step
S34, and if the main power is not off, the flow returns to step S42. To meet again. Therefore,
even if a predetermined time has elapsed during the operation of the touch panel and the flow of
FIG. 43 ends from step 244, the process immediately reaches step 236 again and continues the
operation touch feedback by the touch panel input and the cartilage conduction vibration source
925. it can.
[0211]
The implementation of the present invention is not limited to the above embodiment, and various
modifications are possible. For example, the vibration isolation material 2465 in the twenty-sixth
embodiment is not limited to a material having a band pass filter function to transmit vibrations
of a resonance frequency, and blocks vibrations of a predetermined frequency or more from the
telephone function unit 45 in the voice signal area. And a material having the function of a low
pass filter for transmitting the vibration of the low frequency source 2466 for touch operation
feedback in a frequency range lower than this.
[0212]
A twenty-seventh embodiment of the present invention will now be described with reference to
FIGS. 41 to 43 in the twenty-sixth embodiment. In this case, “touch panel 2468” in FIG. 42 is
replaced with “motion sensor 2468” and “touch panel driver 2470” is replaced with
“motion sensor driver 2470”. The twenty-seventh embodiment uses the cartilage conduction
vibration source 925 as a low frequency output element for feedback of touch feeling in the case
where the cartilage conduction vibration source 925 is also used for the touch operation in the
GUI function of the large screen display unit 205 as in the twenty sixth embodiment. Not only
10-05-2019
83
that, but also as an impact input element for detecting a touch on the mobile phone 2401. For
this purpose, in Example 27, the cartilage transmission vibration source 925 is formed of a
piezoelectric bimorph. The specific configuration for using the piezoelectric bimorph as an
impact input element can be configured by using the block diagram of the fourth embodiment
described in FIG. 9 and the flowchart of the eighteenth embodiment described in FIG.
[0213]
More specifically, the GUI function of the large screen display unit 205 in the twenty-seventh
embodiment is not a touch panel, but as described above, a motion sensor 2468 that detects the
movement of the finger near the large screen display unit 205 without contact. Constructed
using Then, the impact detection function of the piezoelectric bimorph 925 is used as an impact
sensor that detects a finger touch (corresponding to “click” of a mouse or the like) for
determination of the function selected without contact. More specifically, for example, scrolling
on a large screen and selection of an icon are performed by detecting the movement of a noncontact finger, and the touch impact on the mobile phone corresponding to the "click" operation
is shared by using a piezoelectric bimorph. Perform "determination" or "enter" of the operation
by detecting. Since the touch at this time is not on the large screen display unit 205 but on any
place on the outer wall of the mobile phone, the "click" operation can be performed without
leaving a fingerprint on the large screen display unit 205.
[0214]
In addition, the vibration isolation material 2465 in the twenty-seventh embodiment using FIG. It
transmits to the cartilage transmission vibration source 925 which consists of piezoelectric
bimorph. After the cartilage transmission vibration source 925 detects the touch impact of the
finger, the low frequency source 2466 generates a low frequency with a predetermined delay
time to vibrate the cartilage conduction vibration source 925 to perform feedback on the touch
finger. It is common to Example 26. In this case, it is necessary to switch the piezoelectric
bimorph to a function as an input element and a function as an output element. This switching is
performed using the above-mentioned delay time.
[0215]
The implementation of the present invention is not limited to the above embodiment, and various
10-05-2019
84
modifications are possible. For example, the acceleration sensor 49 in FIG. 42 may be used in
place of the impact detection function of the piezoelectric bimorph for detecting the click impact
in the non-contact type motion sensor as in the twenty-seventh embodiment. Further, both of the
function of the acceleration sensor 49 and the impact detection function of the piezoelectric
bimorph may be appropriately combined and used together.
[0216]
Moreover, the combined feature of the cartilage conduction vibration source as the low
frequency vibration source in the twenty-sixth embodiment and the twenty-seventh embodiment
is not limited to the one aiming at touch touch feedback to the finger, and the incoming call to
the mobile phone is notified by silence. It is also possible to use it as a vibrator. In this case, as a
matter of course, the vibration signal introduction of the low frequency source 2466 to the
cartilage conduction vibration source 925 is not touch detection but in response to the incoming
signal, in which case no delay is necessary and vibration signal introduction. Is repeated for a
relatively long time (for example, 2 seconds) intermittently (for example, with a 0.5 second
vibration stop period).
[0217]
The various features described in each of the above embodiments are not necessarily specific to
the particular embodiment, and the features of each embodiment may be modified as appropriate
with the features of the other embodiments as long as their advantages can be utilized. It is
possible to combine or rearrange. For example, the glasses-type stereo portable music player
described above as the modification of the twenty-fifth embodiment of FIG. It is possible to
combine In this case, it is possible to enjoy stereo reproduction from the sound source built in
the music player, and to receive audio signals from the sound source of the mobile phone to
enjoy stereo reproduction. Then, the air conduction microphone or the bone conduction
microphone incorporated in the glasses-type portable music player enables free hand
communication with the mobile phone.
[0218]
The present invention can be applied to mobile phones, portable music players and the like.
