[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
switch-equipped microphone mainly used for vocals and loudspeakers, and a switch for the
microphone and an inner case for the switch-equipped microphone used for the microphone.
[0002]
2. Description of the Related Art FIG. 4 shows a side sectional view of a conventional switchequipped microphone, and FIG. 5 shows an assembly configuration of the same microphone. 26
A square window 27 for mounting is provided, the lead wire 11 of the microphone unit 10 and
the core 14 of the output cord 13 of the microphone are drawn out from the square window 27,
and the lead 11 and the core 14 are soldered to the switch terminal 28 By inserting the adhesive
into the square window 27 on the side of the inner case 1 and fixing the switch 26 with an
adhesive, filling the outlet of the core 14 of the output cord 13 of the microphone at the rear of
the inner case 1 with an adhesive 25 The rear air chamber 22 of the microphone unit 10 is
formed, and the outer periphery of the microphone unit 10 housed in the upper end surface of
the inner case 1 is loosened. The ring 17 is inserted, the inner case 1 is inserted into the inner
surface of the microphone case 16, and the screw portion 20 of the fixing portion 19 of the
windscreen 18 and the screw portion 21 of the microphone case 16 are tightened and fixed. The
method of crimp-inserting the switch outer knob 24 from the square window 23 is put to
practical use.
[0003]
However, since the back air chamber of the microphone unit formed by the inner case made of

synthetic resin is required to be airtight, it is necessary to make a square window for mounting
the switch on the side of the inner case. In order to ensure air tightness in the case of switch
fixation with adhesive and to ensure air tightness by adhesive filling of the core wire outlet of the
microphone output cord at the rear of the inner case, the time until adhesive cure is fixed during
assembly operation. It is inconvenient to install it, and it is inconvenient to insert the core of the
microphone output cord through the hole in the back of the inner case, and with the lead of the
microphone unit lead out from the square window for switch mounting on the side of the inner
case It needs to be connected, requires a lot of working time, and requires a standing place to
cure the adhesive. There has been a problem to say.
[0004]
The present invention solves such conventional problems, facilitates air tightness of the rear air
chamber of the microphone unit, and simplifies the assembly work, and a switch and an inner
case used for the microphone The purpose is to provide
[0005]
SUMMARY OF THE INVENTION In order to achieve the above object, according to the present
invention, a part of the side surface of an inner case made of a synthetic resin that forms the rear
air chamber of a microphone unit is made of metal plating on the synthetic resin. While
providing a switch having a terminal, the terminal pin for the lead wire of the microphone unit
connected by metal plating to the contact terminal and the synthetic resin on the inner surface of
the inner case, the terminal pin for the core wire of the microphone output cord A socket for
connection with a terminal pin is provided at the rear end of the inner case and at the tip of the
lead of the microphone unit and the tip of the core of the output cord of the microphone.
[0006]

terminal for the switch provided on a part of the side surface of the inner case housed in the
inner surface of the microphone case and the lead wire of the microphone unit provided on the
inner surface of the inner case The terminal pins for connecting the core pins of the microphone
output cord provided at the rear of the inner case and the terminal pins of the microphone and
the contact terminals to the terminal pins on the inner surface of the inner case and the terminal
pins at the rear of the inner case are formed of synthetic resin for plating And the other part is
formed of a non-plating synthetic resin by metal plating to form an inner case connected by
metal plating only between the contact terminal and the terminal pin. Attach the switch knob
integrated with the contact spring onto the contact terminal provided on part of the side of the
case, and screw the switch frame The microphone switch integrated with the inner case is formed
by tightening and fixing on the side of the case, and the socket attached to the tip of the lead wire

of the microphone unit is connected to the terminal pin on the inner surface of the inner case. All
wiring work can be completed by inserting the socket attached to the end of the core wire into
the terminal pin at the back of the inner case, insert the inner case into the inner surface of the
microphone case, and store the microphone unit on the upper end face of the inner case Insert
the buffer ring around the periphery of the microphone unit, tighten and fix with the screw part
of the fixed part of the windscreen and the screw part of the microphone case, and press fit the
switch outer knob from the switch square window of the microphone case , Soldering work, Since
it is not necessary to perform the bonding operation of the switch, or the wire insertion operation
and the adhesive filling operation from the inner case rear hole, it is easy to ensure the air
tightness of the rear air chamber of the microphone unit, It is possible to obtain a switchequipped microphone and a switch and an inner case used for the microphone, which have the
advantage of being able to dispense with the settling time and the standing position.
