ABSTRACT:
Herein disclosed is a condenser microphone structure which comprises a microphone housing, a condenser microphone accommodated in the microphone housing to produce a sound signal indicative of a voice sound, first and second terminal connecters provided on the microphone housing in the neighborhood of each other under an insulated state from each other, each of the first and second terminal connecters including a helical spring portion, and an end portion integrally formed with the helical spring portion, the helical spring portion and the end portion being made of an electrically conductive material, the end portions being electrically connected with the condenser microphone to discharge the sound signal from the condenser microphone through the first and second terminal connecters, and an insulating member accommodated in the microphone housing to retain the condenser microphone and the first and second terminal connecters with the microphone housing and to insulate the first terminal connecter from the second terminal connecter. The condenser microphone thus constructed can cause high frequency noises to be reduced to as a small level as possible, and can be produced at a relatively low production price and at a considerably short production period.
