入治具を必要とし。(Problems to be Solved by the Invention) However, in the above microphone fixing method, when pressing the microphone 4 onto the rubber case 3, and when attaching the rubber case 3 fitted with the microphone 4 to the case 1, requires a special press-fitting jig both when press-fitting into hole 2 and when press-fitting.
また固定作業に多大な手間と時間を要するという問題が
あった。Another problem was that the fixing work required a great deal of effort and time.
また、ゴムケース３および樹脂で形成されたマイクロホ
ン取付は孔２の寸法のばらつきによって。Also, the mounting of the rubber case 3 and the microphone made of resin depends on the variations in the dimensions of the hole 2.
圧縮量が過大となりマイクロホン４を破壊したり、ある
いは圧縮量が不足して音響特性が確保できないという問
題があった。There is a problem in that the amount of compression is too large and the microphone 4 is destroyed, or the amount of compression is insufficient and the acoustic characteristics cannot be ensured.
本発明は、上記の問題点を解決するもので、特殊な治具
を必要とせず、マイクロホン取付は孔の寸法のばらつき

る。(Means for Solving the Problems) In order to solve the above problems, the present invention forms a plurality of protrusions inside the hole for microphone mounting, and guides and positions the microphone by these protrusions, and simultaneously mounts the microphone. In this method, a gap is formed between the hole and the inner wall of the hole, and this gap is filled with a filler to fix the microphone.

取付は孔に固定されるので、音響特性が確保される。(Function) Since the microphone is only positioned by being guided by the plurality of protrusions in the hole when mounting the microphone, the tightness will not become excessive due to variations in the dimensions, and therefore the microphone will not be damaged. Furthermore, the outer periphery of the microphone is surrounded by a filler without any gaps, and the microphone mounting is fixed in the hole, so that acoustic characteristics are ensured.

定する。A case 1 of the transmitter/receiver is formed with four projections 5 on the inner periphery for guiding a microphone 4 and a microphone mounting hole 2 with an annular seat 6 formed on the bottom surface. First, when the microphone 4 is fitted into the microphone mounting hole 2, the position of the microphone is determined by the projection 5 and the seat 6, and a gap is formed between the microphone mounting hole 2 and the microphone mounting hole 2. This gap is filled with a filler 7 to fix the microphone 4.
