Conventionally, in a mobile phone, a speaker and a microphone for a call are disposed on one
side of the device body. At the time of a call, the user brings his ear close to the speaker for the
call and listens to the reception voice from the other party.
[0003]
In such a mobile phone, in order to provide clear sound to the user, it may be conceivable to
adopt a so-called cartilage conduction type speaker as a speaker for speech (see Patent
Document 1).
[0004]
The cartilage conduction type speaker includes a diaphragm such as a piezoelectric vibration
element, and vibrates one surface of the device body by the diaphragm.
When the user brings the ear into contact with one side of the device body, the vibration of one
side vibrates the auricular cartilage, the vibration of the auricular cartilage is transmitted to the
tympanic membrane, and the tympanic membrane vibrates. Thereby, the sound is recognized in
the user's brain.
[0005]
JP 2005-348193 A
[0006]
In the cartilage conduction type speaker, a sound wave is generated by the vibration of one
surface of the device body, and the user can recognize the sound also by transmitting the sound
wave to the tympanic membrane.
However, the sound pressure of the generated sound wave is small.

When configured to be provided with a cartilage conduction type speaker, the user can hear
clear sound by keeping the ear in contact with the device body. However, it is not easy for the
user to keep the ear always in contact with the device body during a call without being conscious
of it. When the ear is separated from the device body, the transmission of sound through the
auricular cartilage is interrupted. Although sound is transmitted by sound waves, the sound
pressure is small, and it is difficult for the user to hear the sound.
[0008]
Depending on the sound information obtained during a call, it may not be desirable for the sound
to be interrupted due to the ear being separated from the device body.
[0009]

voice from the first speaker and does not output the receiving voice from the second speaker,
and when a predetermined notification sound is generated, A second control for outputting a
notification sound from the second speaker is performed.
[0011]
In the mobile terminal device according to this aspect, the second speaker may be configured not

Hereinafter, embodiments of the present invention will be described with reference to the
drawings.
[0020]
First Embodiment FIG. 1 is a diagram showing a configuration of a mobile phone 1.
FIGS. 1A and 1B are a front view and a rear view, respectively. FIG. 1C is a partial cross-sectional
view of the cabinet 2 showing the configuration of the call speaker unit SP.
[0021]
Hereinafter, for convenience of explanation, as shown in FIG. 1, the longitudinal direction of the
cabinet 2 is defined as the vertical direction, and the short direction of the cabinet 2 is defined as
the lateral direction.
[0022]
The mobile phone 1 includes a cabinet 2, a display surface 3, a microphone 4, a call speaker unit
SP (a first call speaker 5 and a second call speaker 6), a key operation unit 7, and an external
speaker 8. There is.
[0023]
The cabinet 2 has a substantially rectangular shape when viewed from the front.
A display surface 3 of a display unit, which will be described later, is disposed on the front
surface 2 a of the cabinet 2.
That is, the front surface 2 a of the cabinet 2 is configured by the display surface 3 and the frame
portion surrounding the display surface 3. Various images (screens) are displayed on the display
surface 3.
11-05-2019
6
[0024]
Inside the cabinet 2, the microphone 4 is disposed at the lower end, and the call speaker unit SP
is disposed at the upper end. The call speaker unit SP is composed of the first call speaker 5 and
the second call speaker 6, and mainly outputs a received voice from the other party during a call.
[0025]
A microphone hole 4 a is provided on the front surface 2 a of the cabinet 2 at a position
corresponding to the microphone 4. The voice taken in from the microphone hole 4 a is input to
the microphone 4. The microphone 4 generates an electrical signal according to the input sound.
[0026]
As shown in FIG. 1C, the first call speaker 5 is a so-called cartilage conduction type speaker, and
is constituted of, for example, a piezoelectric vibration element 50. The piezoelectric vibrating
element 50 has a bimorph structure, and includes a shim 50a, and a first piezoelectric ceramic
plate 50b and a second piezoelectric ceramic plate 50c mounted on both sides of the shim 50a.
[0027]
The piezoelectric ceramic plates 50b and 50c are applied with alternating voltages having
positive and negative voltages, respectively, in opposite phases. The application of the alternating
voltage causes the first piezoelectric ceramic plate 50b to expand and the second piezoelectric
ceramic plate 50c to contract, and the first piezoelectric ceramic plate 50b to contract and the
second piezoelectric ceramic plate 50c to expand, thereby repeating the piezoelectric vibrating
element 50 vibrates.
[0028]
The piezoelectric vibrating element 50 is attached to the inner surface of the front surface 2 a of
the cabinet 2 by an adhesive 51.
11-05-2019
7
[0029]
The piezoelectric vibrating element 50 vibrates based on the electrical signal corresponding to
the voice.
When the piezoelectric vibration element 50 vibrates, the vibration corresponding to the voice is
transmitted to the front surface 2a of the cabinet 2, and the front surface 2a vibrates. When the
user's ear is directed to the front face 2a of the cabinet 2, that is, when the front face 2a is
brought close to or in contact with the ear, a sound wave generated by the vibration of the
cabinet 2 enters the ear canal through the ear canal hole. The entered sound wave travels
through the ear canal and vibrates the tympanic membrane. Thereby, speech is recognized in the
user's brain. Furthermore, when the user's ear contacts the front face 2a of the cabinet 2, the
auricular cartilage vibrates by the vibration of the cabinet 2, the vibration of the auricular
cartilage is transmitted to the tympanic membrane, and the tympanic membrane vibrates.
Thereby, speech is recognized in the user's brain.
[0030]
The first call speaker 5, that is, the piezoelectric vibrating element 50 may be attached to the
back surface of the display unit 13 instead of being attached to the back surface of the frame
portion above the display surface 3 as described above.
[0031]
The second call speaker 6 is a so-called air conduction speaker.
A sound wave corresponding to the sound is output from the second call speaker 6. A sound
output port 6 a corresponding to the second call speaker 6 is formed on the front surface 2 a of
the cabinet 2. The sound output port 6a is formed by one hole. The voice or sound wave output
from the second call speaker 6 is emitted to the outside through the sound output port 6a. When
the user's ear is directed to the front face 2a of the cabinet 2, the sound wave emitted from the
sound outlet 6a enters the ear canal from the ear canal hole and vibrates the tympanic
membrane. Thereby, speech is recognized in the user's brain.
11-05-2019

[0032]
As described above, in the first call speaker 5 (piezoelectric vibrating element 50), since the
sound wave is generated by the vibration of the cabinet 2, even if the ear is separated from the
cabinet 2, the user can hear the sound. However, the sound wave due to the vibration of the
cabinet 2 has a smaller sound pressure than the sound wave output from the second call speaker
6. Thus, the sound that reaches the user's ear can be much smaller than the sound from the
second call speaker 6.
[0033]
That is, while the sound from the first call speaker 5 is less likely to leak around than the sound
from the second call speaker 6, when the user removes the ear from the cabinet 2, the sound is
heard compared to the second call speaker 6. It becomes difficult. On the other hand, while the
sound from the second call speaker 6 is more likely to leak around than the sound from the first
call speaker 5, the sound compared to the first call speaker 5 even if the user removes his / her
ear from the cabinet 2 Become easy to hear.
[0034]
A key operation unit 7 is provided on the front surface 2 a of the cabinet 2. The key operation
unit 7 is composed of a plurality of operation keys. Each operation key is assigned various
functions according to the program being executed.
[0035]
Inside the cabinet 2, an external speaker 8 is disposed. The external speaker 8 is an airconduction type speaker as in the case of the second call speaker 6. A sound output port 8 a
corresponding to the external speaker 8 is formed on the back surface 2 b of the cabinet 2. The
sound output port 8a is formed by a plurality of holes. The sound (voice, notification sound, etc.)
output from the external speaker 8, that is, the sound wave is discharged to the outside through
the sound output port 8 a.

[0068]
During a call, the control unit 11 determines whether a predetermined notification sound is
output (S111).
If a predetermined notification sound is not output (S111: NO), the control unit 11 causes the
first call speaker 5 to output a reception voice (S102).
[0069]
When the output of a predetermined notification sound from the first call speaker 5 is started
(S111: YES), the control unit 11 causes the second call speaker 6 to output a received voice
(S112).
The second call speaker 6 outputs a predetermined notification sound and a reception voice.
When the output of the predetermined notification sound ends (S111: NO), the control unit 11
causes the first call speaker 5 to output the reception voice again (S102).
[0070]
<Modification 2 of the First Embodiment> FIG. 5 is a flowchart showing a flow of notification
sound output processing according to Modification 2.
[0071]
In this modified example, the processes of steps S211 to S214 are added to the notification
sound output process of the first embodiment.
Hereinafter, the added processing will be described.
[0072]
11-05-2019
17
The control unit 11 switches the output destination of the predetermined notification sound from
the second call speaker 6 to the first call speaker 5 when the output timing of the predetermined
notification sound is during a call (S202: YES) It is determined whether or not the switching
operation from the second control to the first control has been performed (S211). For example,
one operation key of the key operation unit 7 is assigned to the switching operation.
[0073]
As described above, the sound from the second call speaker 6 is more likely to leak around than
the sound from the first call speaker 5. The user performs the switching operation, for example,
when it is desired to suppress the leak of the notification sound to the surroundings.
[0074]
If the control unit 11 determines that the switching operation has been performed (S211: YES),
the control unit 11 causes the first call speaker 5 to output a notification sound (S212).
[0075]
While the timing at which the output of the notification sound ends is not reached (S213: NO),
the control unit 11 returns an operation to return the output destination of the predetermined
notification sound from the first call speaker 5 to the second call speaker 6 It is determined
(S214).
For example, one operation key of the key operation unit 7 is assigned to the return operation.
The operation keys assigned to the return operation may be the same as or different from the
operation keys assigned to the switching operation.
[0076]
If the control unit 11 determines that the return operation is performed (S214: YES), the control
unit 11 causes the second call speaker 6 to output a notification sound (S203).
11-05-2019
18
[0077]
As described above, according to this modification, the user can switch the output destination of
the notification sound from the second call speaker 6 to the first call speaker 5 in accordance
with the surrounding conditions.
Thus, the convenience of the mobile phone 1 to the user is improved.
[0078]
Second Embodiment In the present embodiment, a reception voice is output from the second call
speaker 6 at the time of a call with a predetermined call destination.
[0079]
The storage unit 12 stores information indicating a predetermined call destination, for example, a
telephone number.
The predetermined call destination is stored in advance in the storage unit 12 when the user
performs a registration operation using a predetermined setting screen. The user registers, for
example, a business partner such as a business partner who wants to avoid interruption of the
received voice as a predetermined call destination.
[0080]
FIG. 6 is a flow chart showing the flow of receiving voice output processing. The configuration
other than the configuration relating to the receiving voice output processing is the same as that
of the first embodiment.
[0081]
When the call is started (S301: YES), for example, the current call destination is determined by
comparing the current call destination's telephone number with the telephone number stored in
storage unit 12. It is judged whether it is the telephone call destination of (S302).
11-05-2019
19
[0082]
If it is not a predetermined call destination (S302: NO), the control unit 11 causes the first call
speaker 5 to output a reception voice (S303).
The control unit 11 does not cause the second call speaker 6 to output a received voice. When
the call ends (S304: YES), the control unit 11 ends the reception voice output process.
[0083]
On the other hand, when it is determined that the call destination is a predetermined call
destination (S302: YES), the control unit 11 causes the second call speaker 6 to output a
reception voice (S305). The control unit 11 does not output the reception voice from the first call
speaker 5. When the call ends (S306: YES), the control unit 11 ends the reception voice output
process.
[0084]
As described above, according to the present embodiment, since the reception voice from other
than the predetermined call destination is output from the first call speaker 5, the user can keep
the cabinet 2 in contact with the surrounding noise, etc. You can hear clear listening speech
without being greatly affected. Furthermore, the leak of the receiving voice to the surroundings
can also be suppressed.
[0085]
Furthermore, according to the present embodiment, since the received voice from the
predetermined call destination to avoid missed calls is output from the second call speaker 6,
even if the ear is separated from the cabinet 2, the user can make a predetermined call I can hear
the incoming voice from the beginning.

<Modified Example of Second Embodiment> FIG. 7 is a flowchart showing a flow of received
voice output processing according to a modified example.
[0087]
In this modified example, the processes of steps S311 to S313 are added to the received speech
output process of the first embodiment.
Hereinafter, the added processing will be described.
[0088]
The control unit 11 switches the output destination of the reception voice from the second call
speaker 6 to the first call speaker 5 while outputting the reception voice from the predetermined
call destination from the second call speaker 6 (this invention It is determined whether or not the
switching operation from the second control to the first control has been performed (S311).
For example, one operation key of the key operation unit 7 is assigned to the switching
operation.
[0089]
The user performs the switching operation, for example, when the surrounding noise is large or
when it is desired to suppress the leakage of the notification sound to the surrounding.
[0090]
When the control unit 11 determines that the switching operation has been performed (S311:
YES), the control unit 11 causes the first call speaker 5 to output a reception voice (S303).
[0091]
When the control unit 11 switches the output destination from the second call speaker 6 to the
11-05-2019
21
first call speaker 5 during a call (S312: YES), the control unit 11 outputs the receiving voice from
the first call speaker 5 to the second call It is determined whether a return operation to the
speaker 6 has been performed (S313).
For example, one operation key of the key operation unit 7 is assigned to the return operation.
[0092]
When the control unit 11 determines that the return operation is performed (S313: YES), the
control unit 11 causes the second call speaker 6 to output a reception voice (S305).
[0093]
As described above, according to the present modified example, the user can switch the output
destination of the reception voice from the second call speaker 6 to the first call speaker 5
according to the surrounding conditions.
Thus, the convenience of the mobile phone 1 to the user is improved.
[0094]
Third Embodiment In the present embodiment, when a switching operation is performed by a
user during a call, a reception voice is output from the second call speaker 6.
[0095]

When the call is started (S401: YES), the control unit 11 switches the output destination of the
reception voice from the first call speaker 5 to the second call speaker 6 (from the first control to
the second control of the present invention) It is determined whether or not the switching
operation (corresponding to the switching operation) has been performed (S402).
For example, one operation key of the key operation unit 7 is assigned to the switching
operation.
[0097]
If there is no switching operation (S402: NO), the control unit 11 causes the first call speaker 5
to output a reception voice (S403). The control unit 11 does not cause the second call speaker 6
to output a received voice. When the call ends (S404: YES), the control unit 11 ends the reception
voice output process.
[0098]
The control unit 11 continues monitoring the switching operation until the call is ended (S402).
[0099]
For example, the switching operation is performed by the user when the user is walking or is in a
situation where the user is swaying in a train or the like, and the ear is easily separated from the
cabinet 2 and the receiving voice is easily missed. The case is assumed.
Alternatively, it may be assumed that the switching operation is performed by the user when the
content of the call is important and the user should not miss the talk.
[0100]
When the switching operation is performed (S402: YES), the control unit 11 causes the second
call speaker 6 to output a reception voice (S405). The control unit 11 does not output the
11-05-2019
23
reception voice from the first call speaker 5. When the call ends (S406: YES), the control unit 11
ends the reception voice output process.
[0101]
The control unit 11 determines whether or not the return operation is performed until the call is
ended (S407). For example, one operation key of the key operation unit 7 is assigned to the
return operation.
[0102]
When the control unit 11 determines that the return operation is performed (S407: YES), the
control unit 11 again causes the first call speaker 5 to output a reception voice (S403).
[0103]
As described above, according to the present embodiment, since the reception voice is output
from the first call speaker 5 if the switching operation is not performed, the user can keep
ambient noise, etc., by keeping the ear in contact with the cabinet 2. You can hear clear listening
voice without being greatly affected by
Furthermore, the leak of the receiving voice to the surroundings can also be suppressed.
[0104]
Furthermore, according to the present embodiment, since the reception voice is output from the
second call speaker 6 by performing the switching operation, the user sufficiently hears the
reception voice even if the ear is separated from the cabinet 2 be able to.
[0105]
Fourth Embodiment In the present embodiment, when a user's ear that has been in contact with
the cabinet 2 leaves the cabinet 2 during a call, a reception voice is output from the second call
speaker 6.

FIG. 9A is a diagram (front view) showing the configuration of the mobile phone 1.
FIG. 9 (b) is a flowchart showing the flow of the receiving voice output process.
[0107]
In the present embodiment, the proximity sensor 9 is disposed at the upper end portion of the
cabinet 2.
The proximity sensor 9 has its sensitivity adjusted so that a detection signal is output to the
control unit 11 when the user's ear touches the proximity area of the proximity sensor 9 on the
front surface 2 a of the cabinet 2. The proximity sensor 9 may be disposed at any position of the
cabinet 2 as long as the presence or absence of ear contact with the front face 2 a of the cabinet
2 can be detected.
[0108]
When the control unit 11 receives a detection signal from the proximity sensor 9, it determines
that the ear has touched the cabinet 2, and determines that the ear has left the cabinet 2 when
the detection signal disappears.
[0109]
The configuration other than the configuration relating to the receiving voice output processing
is the same as that of the first embodiment.
[0110]
The reception voice output process will be described with reference to FIG. 9 (b).
[0111]
11-05-2019
25
When a call is started (S501: YES), the control unit 11 determines whether the user's ear has left
the cabinet 2 (S502).
This determination is initiated after it has been detected that the ear has first touched since the
call started.
[0112]
If the ear is in contact with the cabinet 2 (S502: NO), the control unit 11 causes the first call
speaker 5 to output a reception voice (S503).
The control unit 11 does not cause the second call speaker 6 to output a received voice.
When the call ends (S504: YES), the control unit 11 ends the reception voice output process.
[0113]
The control unit 11 continues monitoring whether the user's ear has left the cabinet 2 until the
call is ended (S502).
[0114]
When the control unit 11 detects that the ear has left the cabinet 2 (S502: YES), the control unit
11 causes the second call speaker 6 to output a reception voice (S505).
The control unit 11 does not output the reception voice from the first call speaker 5. When the
call ends (S506: YES), the control unit 11 ends the reception voice output process.
[0115]
The control unit 11 determines whether the ear has touched the cabinet 2 until the call is ended
(S507).
11-05-2019
26
[0116]
If the control unit 11 determines that the ear is in contact with the cabinet 2 (S507: YES), the
control unit 11 causes the first call speaker 5 to output a reception voice again (S503).
[0117]
As described above, according to the present embodiment, when the user's ear is in contact with
the cabinet 2, the reception voice is output from the first call speaker 5, so the user is not greatly
affected by ambient noise and the like. Can hear the clear reception voice.
Furthermore, the leak of the receiving voice to the surroundings can also be suppressed.
[0118]
Furthermore, according to the present embodiment, since the received voice is output from the
second call speaker 6 if the user's ear is separated from the cabinet 2, the user can receive the
received voice sufficiently even if the ear is separated from the cabinet 2. You can listen to
