Diaphragm.
[Detailed Description of the Invention] 111. . 4-,-! T2 The present invention relates to a
reverberation microphone, which can easily be formed into a good-looking microphone. For
example, as shown in FIG. 1, the microphone case 1 is provided with the sound receiving unit 2,
and the output of the sound receiving unit 2 is added to the diaphragm 4 via the reverberation
body 3 made of, for example, a spring The vibration of 4 is received by the microphone unit 5,
and the microphone unit 5 is a reverberation sound. . However, in the case of this seven-in-one
device, it is necessary to provide the sound receiving unit 2 and the vibration plate j. There is still
a drawback that the lateral vibration of the elastic body 3 occurs and the sound quality is easily
deteriorated. In addition, it is troublesome to attach the elastic body 3 made of the swinging
stupid. The four bundles are free of these nine defects. When manufacturing the above-described
remicrophone, the same elastic bodies 161 and 162 are connected to form one elastic body 16.
Further, a hole is provided at the center of the sound receiving diaphragm 17. However, the
elastic body 16 is inserted through the hole, and the vicinity of a portion of the elastic body 16 in
the -L region is identified by the adhesive etc. as the receiving diaphragm 17. The microphone of
this configuration has only the sound receiving diaphragm 17 in which the sound receiving unit
2 and the diaphragm 4 in FIG. 1 are shared, so to speak, the structure is simple. Also, there is no
fear of lateral vibration of the elastic body 16. The embodiment will be described below with
reference to FIG. Here, 11 is a microphone case, 12 is a windshield, 13.14 is a microphone unit,
15 is a support case of the microphone unit 14 and the elastic body 16 [161, 162] and the sound
receiving diaphragm 17, and is fixed in the microphone case 11. . The reference numeral 18 is a

changeover switch for switching the output of the microphone units 13 and 14, and is a
microphone unit. The output of the output 13 is output, the output of the microphone unit 14 is
output only, the combined output of the microphone units 13 and 140 is output, and the output
of the microphone unit 13 and the output 14 is cut. Further, as shown in FIG. 3, in a state in
which one end of one elastic body 162 is inserted into the hole of the diaphragm 17, integration
of the elastic bodies 161 and 162 and integration of the elastic body 16 and the receiving
diaphragm 17 are achieved. Even if 1. The elastic body 16 may be fixed to the case 11 instead of
the support case 16, and the constants of the elastic bodies 161 and 162 may be the same or
161 and 162 may be different. As a means to make it different, the elastic body itself can be
considered to be a method of using another one or a case of forming a composite. In this case, if
the constants of the extensibility bodies 161 and 162 are the same, it will be possible to
approach natural reverberation if the reverberation becomes a single reverberation or different,
as described in the following example column. According to the present invention, since the
sound receiving diaphragm is provided in and in the vicinity of the extensible body, the number
of the diaphragm may be one.
The vibration plate can still prevent V = shake of the elastic body. Furthermore, the receiving
diaphragm can be lanced in the restraining state, and the D adjustment root can be easily
adjusted when setting the outer circumference of the outer circumference to the supporting case.
As a result, a reverberation microphone with excellent characteristics can be provided.
