ａが前面より突出して形成されている。 In FIGS. 1 and 2, a rubber cap 1 for attaching and sealing the ECM is made of an elastic material such as synthetic rubber, and has a cavity 1a inside.
Electret condenser microphone (ECM) 6 is built into a so that there is no gap. Approximately in the center of the front of the case installation side of rubber cap 1
A MIC hole 7 is provided, and a sloped portion 1b is formed concentrically with the MIC hole 7, creating a space opening through the MIC hole 7 to the front surface on the case mounting side. Further, there are circular elastic protruding ribs 2, 2 which surround the space along the inclined portion 1b and uniformly abut against the inner surface of the case on the front surface of the case mounting side.
A is formed to protrude from the front surface.

様に密着し、音が漏れない構造となる。 When the case fitting protrusion 8 of the rubber cap 1 with the ECM 6 attached is fitted to the fitting bracket 4 of the chassis 3 configured in this way, the ribs 2, 2a, 2b on the front surface of the rubber cap 1 are uniformly formed on the inner surface of the chassis 3. The structure is such that it fits tightly to the body and prevents sound from leaking.

る。[Effects of the invention] As is clear from the above embodiments, according to the invention, a microphone hole is provided on the front surface of the ECM mounting/sealing rubber cap at approximately the center of the front surface of the case mounting side. An elastic protruding rib is provided on the front surface of the case installation side that surrounds the open space and contacts the inner surface of the case, so the front and back surfaces are reliably separated acoustically, creating a structure that prevents sound from leaking. This ensures sound collection and provides good acoustic characteristics. Furthermore, since packing and the like are not required and the ribs are integrally molded, it can be constructed from a single component, making it easy to assemble and producing a low-cost product.
