DESCRIPTION JPH0662658
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
microphone unit device, and more particularly to a microphone unit having a microphone fitting
recess for mounting a transmitting microphone of a telephone, a modular jack used for
connection of a telephone line, etc. It relates to the device.
[0002]
2. Description of the Related Art On the transmitting side of a telephone handset, a microphone
unit device provided with a chip type microphone (ECM), a modular jack and the like is provided.
The conventional microphone unit device includes a structure (not shown) housed and held in
the housing, the modular jack 1 and the microphone 2 shown in FIG. 3, etc., and the microphones
are in the microphone fitting recess of the above structure. It was housed and held, and the
modular jack 1 was to be attached to the jack attachment portion of the above structure. The
modular jack 1 and the microphone 2 are connected using the lead wire 3. The reference
numeral 4 denotes a lead wire guided to the receiving side, and 5 denotes a caulking fitting for
connection to the terminal on the receiving side.
[0003]
However, according to the conventional microphone unit device, it is necessary to separately
attach the microphone 2 and the modular jack 1 to the structure incorporated in the housing.
There is a problem that the number of assembling steps to the housing is large, there is a
01-05-2019

problem that the modular jack 1 and the microphone are connected by the lead wires 3 so that
erroneous wiring is easily generated, and the number of parts increases and the assembly
becomes complicated. The
[0004]
The present invention has been made in view of the above problems, and a modular connector
such as a modular jack is integrally formed with a structure for attaching a microphone, and the
terminals of the modular connector are not used without lead wires. By being able to directly
connect to the microphone attached to the structure, it is possible to easily reduce the number of
parts, the number of assembling steps of the microphone unit device to the housing, the
prevention of erroneous wiring, etc. Aim to provide microphone unit device
[0005]
SUMMARY OF THE INVENTION In the microphone unit device according to the present
invention, a microphone fitting recess and a plug connector of a modular connector are provided
in a structure accommodated and held in a housing such as a telephone handset housing. And
the longitudinal middle portion of the terminal having the distal end portion disposed at the
insertion portion of the modular connector is fixed in the vicinity of the insertion portion, and the
proximal end portion of the terminal is fitted in the microphone fitting recess It is connected to a
wiring board on which the combined microphone is mounted.
[0006]
According to this configuration, since the insertion part of the modular connector is provided in
the structure for attaching the microphone, the insertion part (this insertion part excludes the
terminal in the modular jack shown in FIG. 3, for example) It is not necessary to provide a
separate part, that is, a housing provided with a plug insertion recess, and moreover, the terminal
of the insertion part (this terminal corresponds, for example, to the terminal of a modular jack)
Since the base end of the terminal is fixed at the place and connected to the wiring board on
which the microphone attached to the structure is mounted, the lead wire becomes unnecessary,
the number of parts is reduced accordingly, and the number of assembling steps And there is no
room for miswiring.
[0007]
Furthermore, even when the mating modular connector is inserted into and removed from the
above-mentioned plug-in part, even if the plug-in part moves, the movement of the plug-in part
affects the entire structure on which the wiring board is attached and the whole structure moves.
Therefore, it is difficult for the force to peel off the connection between the terminal and the

wiring board.
[0008]
FIG. 1 is a cross-sectional view of a microphone unit device according to an embodiment of the
present invention incorporated in the transmitting side of a housing 6 of a telephone handset,
and FIG. 2 is a plan view showing a structure 7 of the microphone unit device. FIG.
[0009]
The structure 7 made of synthetic resin is formed in such a shape that its outer contour is
accommodated and held in the housing 6 and has a microphone fitting recess 71 formed of a
round hole at the center, It has a plug-in portion 72 provided with a recess 73 into which the
modular plug P is inserted at the front end.
The reference numeral 8 denotes a terminal, the tip end 81 of which is protruded inside the
recess 73 of the insertion portion 72, and the longitudinal middle portion 82 is press-fitted and
fixed in a mounting hole 74 formed in the wall of the insertion portion 72 There is.
The microphone 9 is mounted on the wiring board 10, and the lead terminals 91 of the
microphone 9 are soldered 101 to the pattern of the wiring board 10.
Then, the microphone 9 is fitted and held in the microphone fitting recess 71 of the structure 7,
and the wiring board 10 is engaged with and fixed to the plurality of engaging claws 75 provided
on the structure 7. The base end 83 of the terminal 8 is soldered 102 to the pattern of the wiring
board 10.
[0010]
Reference numerals 200 and 300 respectively denote compressed pads for improving the
acoustic characteristics, but the pad 300 interposed between the structure 7 and the housing 6 is
made of the structure 7 by the recovery action accompanying compression. I'm suppressing the
cling.

[0011]
When the structure 7 is incorporated into the housing 6, the microphone 9 mounted on the
wiring substrate 10 is fitted and held in the recess 71 before the incorporation, and the base end
83 of the terminal 8 is the wiring substrate 10 The microphone unit device is completed by
soldering to a pattern, and then the structure 7 is incorporated into the housing 6.
In this way, the process of assembling the housing 6 is only one process.
[0012]
According to the above construction, since the longitudinal middle portion 82 of the terminal 8 is
fixed to the attachment hole 74 of the insertion portion 72, the terminal 8 is surely connected to
the predetermined pattern of the wiring board 10 Therefore, there is no room for miswiring.
And since the insertion part 72 plays a role as a modular jack, when the modular plug P on the
telephone line side is inserted into the insertion part 72, the terminal 8 which protrudes in the
recess 73 of the insertion part 72 in the terminal of the modular plug P The tip portion 81 of the
is in contact and electrical conduction is performed. Furthermore, even if the plug portion 72
moves when inserting and removing the modular plug P in the plug portion 72, the movement of
the plug portion 72 affects the entire structure 7 to which the wiring substrate 10 is attached
and the structure As the whole 7 moves, it is difficult for the force to peel off the connection
between the base end 83 of the terminal 8 and the pattern of the wiring board 10
[0013]
In this embodiment, the insertion portion 72 is provided with the recess 73 to function as a
modular jack, but the insertion portion can be configured to function as a modular plug. In that
case, a modular jack (not shown) is inserted. In addition, the microphone unit device of the
present invention can be incorporated into other housings as well as the telephone housing and

persisted.
[0014]
As described above, according to the microphone unit device of the present invention, it is easy
to reduce the number of parts, to reduce the number of assembling steps of the microphone unit
device to the housing, and to prevent erroneous wiring and the like. The effect is that you can In
addition, even if the insertion portion moves when inserting and removing the mating modular
connector, the adverse effect due to the movement does not easily reach the connection portion
between the terminal and the wiring board, so that peeling is hardly generated at the connection
portion.
