Detailed Description of the Invention This device is a side light. The present invention relates to a
transducer suitable for a device that is required to be compact and lightweight, such as a wireless
earphone device. For example, in a wireless earphone device, it is desirable that the device be
small and lightweight so that the device body can be worn on the ear. In this case, in particular, it
is necessary to improve the transformer, which is accommodated in the main body of the
apparatus, for example, a sound generator for converting an electrical signal into a blue sheet. In
the conventional sound generation part, it is difficult to thin the magnetic material that
magnetically connects the magnetic path and the magnet, and it is difficult to electrically connect
the magnetic material and the sound generation part. It was difficult to assemble on the same
electrical weight (receiver) and one weight each to supply the signal. Therefore, it was difficult to
miniaturize, and separately assembled, it was possible to get an influence on the sound quality
because the j-Hl isolation was bad. Is this device made based on the above circumstances? (1) By
using a printed circuit board on a printed wiring board with a magnetic substance that couples
magnetic paths and magnodes, it is possible to improve the assembly accuracy and sound quality,
and to make the device smaller and more compact. -Stones that serve as a catalyst. This invention
will be described ten times with reference to the drawings, except for this invention 0-1. In FIGS.
1 (a), (b), (c) and (d), 11 is a main body of the earphone device. The ear surface 12 of the main
body of the earphone chopstick is provided with a plurality of through holes 13 through which
the sound generated by the sound generation unit 23 described later passes. It is done. Further,
the earphone device main body 11 is provided with a loop-shaped earpiece 14 substantially
concentrically. That is, this ear hook is integrally formed on the lower end portion of the
earphone device main body 1 by the connecting portion 141. This ear hook is made of a flexible
resin or the like as shown in FIG. 1 (b). As shown in (d), it is inclined at a predetermined angle.
Thus, in the state where the ear hook is attached to the ear 7, the through hole 13 of the ear pad
12 faces the external ear canal. It is 1 and 15 is a power switch. On the other hand, inside the
earphone device body and inside the ear hooks, for example, the receiving antenna 21 shown in
FIG. 2, the receiving unit 22, the sound emitting unit 23, and the power source described later
are provided in the unit 14. That is, as shown in FIGS. 1 (e) and 1 (d), the receiving antenna 2 is
accommodated in the groove 14 provided along the agricultural surface (the part corresponding
to the human body) of the part 14, and the loop is looped. The L1 receiving unit 22 and the
sound generating unit 23 Fi are housed in the earphone device main body 1 and the sound
generating units z and 3 are disposed to face the through holes 13 provided in the ear pad 12. .
Thus, an unshown example received by the antenna 21 is an FM modulated wave or an AM
modulated wave sent out from the main body of a blue-collar device such as an amplifier or the
like, detected and amplified by the receiver 22 and converted to blue-blue by the sound
03-05-2019

generator 23. It is made possible to hear. The antenna 21 is covered by the insulating member
24 in a state in which the ear hooks are accommodated in the groove portion 141 of the portion
14. Further, when the power switch 15 is turned on, the receiver 22 and the like are supplied
with power from a battery provided in the earphone device main body 11 to be in an operating
state. According to the above configuration, since the ear hook is provided with the antenna 21
in the form of a loop in the portion 14, the ear hook can share the portion 14 for holding the
main body of the earphone device and the disposition of the antenna 21. Since the size can be
increased, the reception sensitivity can be improved. In addition, since the ear hooks are in a loop
shape and inclined with respect to the ear display device attachment 14, the ear whiteness in the
state of being attached to the ear is appropriate for the ear white part 12 or the ear Abut!
Therefore, it is difficult to remove from the ear, and the sound quality can be improved because
the leaked sound is reduced. In addition, if the ear hooks are provided with an elastic body such
as silicone rubber or urethane on the back surface of the part 14, looseness in close contact with
the ear is reduced, and the eyelids are comfortable. Become. Next, the attachment structure of the
antenna 21 will be further described with reference to FIG. The same reference numerals as in
FIG. 1 denote the same parts in FIG. FIG. 3 (,) shows that the ear hooks are formed along the
surface of the groove 14. , And this groove portion 14. The antenna 21 is completely disposed
inside to form a rouge-like antenna. In such a configuration, it is a mouth function to omit the
insulating member 24 which is not shown in FIGS. 1 (c) and 1 (d). Furthermore, in the case of the
ear-tear 73 (b), the antenna 21 is inserted with the inside of the bar portion 14 being hollow and
the antenna 21 is formed to form a louso-like antenna, and in FIG. 21 is integrally formed. The
same effect as described above can be obtained with such a configuration. Furthermore, the ear
hooks are formed of, for example, a conductive rubber or the like, and the ear hooks are formed
of the portions 14 themselves! Good as a square antenna. However, in this case, the ear hooks
need to insulate the back surface of the portion 14. Next, misrepresent the switch mechanism
using F4. Seedlings, the same parts as in FIG. 1 are denoted by the same reference numerals, and
this switch mechanism is used to supply power to the receiving unit 22 and the like provided
inside the main body 11 with the earphone main body 11 attached to the ear. In the state where
the power is supplied and the main body 11 is removed from the ear, the power is turned off.
4 (a) and 4 (c), the ear piece is attached to the ear, and the ear hooks are provided on the front
printing body of the portion 14 [the ear piece 11 of the earphone device. That is, the ear hook is
provided in the inside of the earphone device main body 1) so that the connecting portion 14 ?
of the portion 14 can freely move forward and backward. At the inner end portion of the main
body 11, a movable contact piece 31 constituting a switch mechanism is provided as shown in
FIGS. 4 (b) and 4 (d). Further, a fixed contact piece 32 ░ 33 is provided inside the earphone
device main body 11 at a predetermined interval in the advancing / retracting direction of the
connecting portion 14 ░, for example. A power supply and reception unit 22 and the like are
connected. In addition, the connection unit 14. In the case of the above configuration where the
earphone device main body 1 is not attached to the ear in the above-described configuration, the

connecting portion 141 and the ear are not illustrated. Since the hooking portion 14 is biased 4.4
in the direction of the arrow A with respect to the earphone device main body 11, the movable
contact 31 is separated from the fixed contact piece 32.33 and turned off as shown in FIG. 4 (b)
It is in the state. In this state, when the earphone device main body is attached to the ear against
the biasing force of a spring (not shown), the connection h14 + and the ear hooks are shown by
the arrow B in FIG. Actuated in the direction, the movable contact piece 31 bridges the fixed
contact pieces 32 and 33 to be turned on. Therefore, power is supplied to the receiver 22 and
the like, and the receiver 1g becomes ready. In this state, the main body of the earphone device 1
and the ear hooks are not attached to the ear 14. The ear 14 and the connector 14I are not
shown in FIG. The switch state is also turned on as shown in FIG. According to the above
configuration (Go earphone device body No. and ear hooks are in a switch-like state when the
portion 14 is not attached to the ear, and the switch is in the on state, and when attached to the
ear, the receiver 22 is powered on. Because when you are not using it? 1Restrain the quality, that
is iJ ability. It should be noted that the structure of the switch is not limited to the movable
contact piece 31 and the fixed contact piece 32 and 3 provided separately, for example, a micro
switch is provided in the earphone device main body 11, and the movable hand of this switch ,
And the switch state may be switched. Next, ear feeding will be further described with reference
to FIG. The same reference numerals as in FIG. 1 denote the same parts in FIG.
Human ears vary in size and type depending on individuals. Thus, the earplugs have a heart wall
which is supposed to be in accordance with the differences between these individuals. In FIGS. 5
(a) and 5 (b), the ear hooks are separated at both ends of the portion 14 and provided on the
main body 11 that is to be worn as an earphone so as to be able to be pulled out and moved back
and forth. Further, in the earphone device main body 11, the ear hooks are welded to the portion
14C, and the pressing portion side 41 is welded around the both end portions, and a locking of
the ear sheet 14 is provided. According to such a configuration, the entire length of the ear
hooking portion 14 is changed by ol by advancing and retracting the both ends of the ear
hooking portion 14 with respect to the main body of the earphone device, and adjustment
according to each person may be required. It is possible. In Fig. 5 (c), the ear hooks are provided
with a joint mechanism between both ends of the portion 14 and the main body of the earphone
device. That is, the ear hooks are provided with a plurality of hemispherical or semi-cylindrical
concave portions 42 and 43 in the both ends of the portion 140 and the earphone it main body
11, respectively. A spherical or cylindrical rigid body 44 is provided in each of the opposing
concave portions 42.43, so that the concave portions 42 provided in the portion 14 cross over
the rigid body 44. The ear hooks operate the portion 14 so that the entire length of the portion
14 can be easily adjusted. In addition, it is convenient because the adjustment state does not
easily change due to the articulation mechanism, and in FIG. 5 (a), (b) and (c), the ear hook is
arranged with the looped antenna 21 in the portion 14. Although it is provided, the holding
member 41 and the rigid body 44 etc. are illustrated by a gold tank, for example * hljL, the
antenna 21 and the electric E of the receiver 22! In order not to change the total length of the
03-05-2019
4
antenna 21, it is preferable to connect both ends of the antenna 21 and the receiving unit 22 by,
for example, a wire member longer than the moving distance of the unit 14. Furthermore, in FIG.
6, it is possible to provide the switch mechanism shown in FIG. 5 as well, and in FIG. A plurality
of metal cylindrical members are connected to form a stretchable slot 4 and the ear hook is blunt
so that the full length pipe of the portion 14 can be varied. That is, as shown in FIG. 6, the ear
hooks are looped by alternately connecting a cylindrical member 45 having a large diameter and
a cylindrical member 46 having a diameter smaller than this member 45, as shown in FIG. The
both ends of the earpiece 14 are fixed to the earphone device body 1. In this state, the cylindrical
member 46 advances and retracts into 45, and the ear hooks are adjusted so that the entire
length of the portion 14 is adjusted.
The cylindrical members 45 and 46 are prevented from pulling out each other and are not easily
moved. Even with such a configuration, the ear hooks can adjust the total length of the portion
14 according to each person. Also, if the cylindrical members 45 and 46 are combined, for
example, in the form of a so-called flexible 4 tab, the ear hooks can arbitrarily deform the shape
of the portion 14. Further, in the above configuration, the antenna 21 is disposed in the
cylindrical member 45.46. In this case, the ? cylindrical portion 45.46 and the antenna 21 are
insulated. It is also possible to use the cylindrical member 45.46 itself as the antenna 21.
However, in this case, it is necessary to provide an insulating member at a portion and a portion
in contact with the human body. Next, FIG. 7 is month 1 and the earpieces will be further
described. The same reference numerals as in FIG. 1 denote the same parts. In FIG. 7 (,), the
earpieces 14 are formed by an elastic body, and the shape thereof is substantially the same as
that of the human ear. In such a configuration, when the ear hook is attached to the ear, the ear
hook 14 is deformed as shown in FIG. 7 (b) according to the shape and size of each person's ear. .
With such a configuration, the ear hook can attach the portion 14 and the earphone device body
1 substantially regardless of the shape and size of the ear, and it is difficult for the attachment
etc to occur. It is. In addition, since the positioning of the 2 earphone device main body 11 with
respect to the ear becomes firm, it is possible to further improve the sound quality. The looped
antenna 21 is provided inside the earpiece 14. Next, the antenna 21 will be further described
using FIG. The same reference numerals as in FIG. 1 denote the same parts in FIG. In FIGS. 1 to 7,
the antenna 21 and the human body are insulated in order to prevent the occurrence of wrinkles
at the resonance frequency (tuning frequency) due to the contact of the antenna 21 with the
human body. Here, the antenna 21 is in contact with the human body, and the human body is
used as a part of the antenna. In FIG. 8 (,), the ear hook is provided with a contact portion 51 at
the Ik curved surface portion of the portion 14. The antenna 21 is cut off as shown in FIG. 8 (b),
and the cut portion 52 is exposed. Thus, the ear hooks come into contact with the human body in
a state in which the ear hook is attached to the ear, and the ear hook is used as a human body Fi
contact grounding hollow midline grounding portion. However, in this case, 13 impedance
matching between, for example, the receiving side and the human body is taken.

With such a configuration, the human body can be used as an antenna, and the reception
sensitivity can be improved. In addition, as the contact portion 51, the ear hook may be provided
not only in the portion 14 but in, for example, the ear white portion 12. In addition, if the contact
portion 51 is formed of an elastic member, for example, the separation portion 52 can be further
closely attached to the human body. Furthermore, in this example, the separation portion 52 of
the antenna 21 may be in direct contact with the human body, or the antenna 21 and the human
body may be capacitively coupled. Next, the integrated circuit element with a power supply
terminal will be described by way of example using FIG. 19 as the earphone device main body 11
is worn on the ear, so it is small enough not to cause discomfort in the worn state. There is a
need to reduce the weight. For this reason, for example, reduction in size and weight of
components accommodated in the earphone device main body 11 is desired. In FIG. 9 (&),
reference numeral 61 denotes an integrated circuit element in which integrated circuit chips
constituting, for example, the receiving unit 22 and the like 4 are accommodated. The surface of
the integrated circuit element 61 is provided with positive and negative battery terminals 62.63.
The battery terminal 62.63 is electrically connected to the integrated circuit and is adapted to
hold the battery 64. With such a configuration, it is not necessary to separately provide a space
for arranging the battery 64, and it is possible to make the earphone device main body 11 into a
cabin. Still, FIG. 9 (b) shows a recess 65. 6 for accommodating the battery 66 on the surface of
the integrated circuit element 650. , And this recess 65. The positive and negative battery
terminals 61 and 68 made of an elastic material are provided on the bottom and side wall surface
portions of the above. With such a configuration, it is possible to take out the electric power of
the pond 66 through the battery terminal 67. 68, and the battery 66 has a recess 65. Since the
thickness of the battery 66 is offset because it is housed inside, it is possible to further reduce
the size and weight of the earphone device body 1. In FIG. 9 (()) and ((b)), the battery terminals
63 and 61 are not limited to being provided on the integrated circuit element 61. 65. For
example, they are provided on the earphone device main body 11 side and electrically connected
with the battery 64. You may Further, in this case, the power supply may be disconnected by, for
example, a power supply switch through an integrated circuit. Next, with reference to FIG. 10, a
transducer, that is, a sound generator 23 for converting an electric signal into a youth signal will
be described. In FIG. 10 (,), (b) 71 is a printed wiring board. An electric circuit, for example,
components 72. .
72,. 723 are disposed, and on the back surface of the substrate 71, conductive patterns or turns
73 for connecting these components 7211721 + 72B are formed by printing. Further, on the
back surface of the printed wiring board 71, a ring-shaped magnet 73 constituting a sound
generating unit 22 such as a magnetic type transformer, a magnetic path example such as a pole
24 and 6 connected to the receiving unit 22. The lure 5 and the sound generator 76 are disposed
as appropriate. Further, a magnetic substance 77 which is a purported effect is formed on the
back surface of the printed wiring board 7 by etching, for example. As shown in this magnetic
03-05-2019
6
body 771'i, as shown in FIG. 6), it comprises a ring-shaped portion 77 ?, a circular portion 771,
and a connecting portion 773 connecting the circular portion 77 and the ring-shaped portion 77.
It is provided in contact with the pole 74 (иии each ring 7711 circular portion 77). Therefore, the
conductive (the turn 73 is formed in a portion other than the magnetic body 77). According to
the above configuration, since the magnetic body 77 is formed by printing on the back surface of
the printed wiring board 71, the magnetic body 77 can be formed extremely thin, and the
strength of the magnetic body 77 can be obtained by the printed wiring board 71. Further, since
the magnetic body 77, the printed wiring board 71, the ring-shaped magnet 73 and the magnetic
path 74 can be assembled integrally, the accuracy is improved, and the sound quality is improved
with good air tightness zb7. In addition, since it is possible to assemble to a single weight,
downsizing and reduction of manufacturing costs can be easily performed. Next, the earphone
device main body 11 will be further described with reference to FIG. The same reference
numerals as in FIGS. 1 and 2 denote the same parts. In the above description, the earphone
device main body 11 is a wireless system for receiving a signal sent from the sound device main
body, but here, between stations is used for an example in which wireless and wired can be
switched as desired. In FIG. 11 (a), reference numeral 81 denotes a plug connected to the sound
device main body such as an amplifier, for example, and 22 is detachably connected to the
earphone device main body 11: 10 jigs. In the middle of the plugs 81 and 82, a transmitter 83 is
provided. The transmitter 83 transmits the signal sent from the sound device main unit by AM
modulation, and it is orange with the cord 84 (the antenna of the transmitters 8 and 7). The
transmitter 83 is also provided with a wired / wireless changeover switch (not shown). When the
switch selects wired, the signal input from the connector 81 is directly led to the connector 82.
When wireless is selected, the signal input from the connector 81 is modulated by the
transmitter 83. It is sent out via a post code 84.
On the other hand, the circuit configuration accommodated in the earphone device main body 11
is as shown in FIG. 11 (b). That is, 85 is a jack to which the plug 82 is connected. The movable
contact piece 85 of the jack 85 is connected to the fixed contact piece 85 when the plug 82 is
detached, and the output signal of the reception unit 22 is led to the sound generation unit 23!
When the lug 82 is inserted into the jack 85, the connection is switched to the fixed contact piece
853, and a wired signal is led to the sound producing unit 23. In the case of wireless of the
power supply switch 15, the on-state one character is added and the power of the built-in battery
86 is supplied to the receiving unit 22 and the like. The battery 86 is charged using a portion of
the signal wired by the 987 charging circuit. According to the configuration described above, the
earphone device main body 11 can be wirelessly or wiredly connected by switching and
connecting the plug 82 detachably connected to the earphone device main body 11 and the
changeover switch used for the transmitter 83 as desired. It is possible to use. Therefore, a highly
useful usage is possible. Further, by using the cord 84 as an antenna of the transmitter 83, it is
convenient because there is no need to separately provide an antenna. Furthermore, since the
battery 86 can be charged by a part of the signal guided through the wire in the case of the wire,
03-05-2019

the life of the battery 86 can be extended. If two circuits shown in FIG. 11 (b) are arranged in
parallel, it is possible to obtain a wireless headphone device. That is, FIG. 12 (,) shows -example 0
of the circuit, and the same reference numerals as in FIG. 11 (1) denote the same parts. In the
figure, 91.92 are amplifiers for the right channel and the left channel, respectively, and the
output signal of the receiving unit 22 is supplied to this amplifier 91.92. Also, the output signal
of the amplifier 91.92 is supplied to the sound generator 95. 96 for the right channel and the left
channel through the jack 93 ░ 94, respectively. This circuit and the sounding body 95.96 etc.
are appropriately filmed in the headphone device 97 shown in FIG. 12 (b), and the plug 911. .
The headphone device 91 can be switched to the wired state or the wireless state and used by
attaching and removing the 98 ? to the jack 93.94. In addition, the plug 98. Is connected to the
sound device main body (not shown). As described above in detail, according to this invention,
assembling accuracy and sound quality can be achieved by printing on a printed wiring board a
magnetic material that couples a magnetic path and a magnet, and the apparatus can be
miniaturized. A transducer can be provided.
