Abstract
It is an object of the present invention to securely prevent a generation of an acoustic resonance due to a rear air chamber of a capsule support in a capacitor microphone including a microphone capsule and the capsule support and to improve assembly of a contacting terminal which is mounted in the capsule support. According to FIG., a capacitor microphone of the present invention includes a microphone capsuleand a capsule supportA which are connected through a connecting screw. A contacting terminalcontacting to a contact pinof the microphone capsuleis disposed on the printed circuit boardhoused in the capsule supportA with an electric insulating blockheld in the contacting terminaland is fixed through the blockand an electric insulating cap member. Whereby, the cap memberincreases the air proof grade of a rear air chamber and makes the air volume of the chamber as small as possible and constant so that an acoustic resonance is not generated.
