Patent ID: 6961437

Claim:
A capacitor microphone including a microphone capsule and a capsule support connected to each other through screw latching means, a vibrating plate and a fixed electrode disposed in the microphone capsule with the vibrating plate and the fixed electrode facing to each other, a contact pin extracted from the fixed electrode toward the capsule support, the capsule support including a printed circuit board and a contacting terminal, the printed circuit board having an impedance converter, the contacting terminal electrically contacting to a given terminal of the impedance converter, the contacting terminal formed with a plate spring elastically contacting to the contact pin, the microphone capsule and the capsule support connecting to each other through the screw latching means whereby the microphone capsule and the capsule support electrically contacting to each other, the capacitor microphone comprising: the printed circuit board mounting the impedance converter on the back surface relating to the microphone capsule of the circuit board; an electrode pattern electrically connecting to the given terminal of the impedance converter through predetermined conducting means, the electrode pattern formed on the front surface relating to the microphone capsule of the printed circuit board; the contacting terminal including: a bottom plate contacting to the electrode pattern; a side plate extending at a substantially right angle toward the microphone capsule from one end of the bottom plate; a contacting piece obliquely extending in the upper direction at a designated angle from the top end of the side plate; wherein the contacting terminal is formed in a substantial U-shape with the bottom and the side plates, and the contacting piece; an electric insulating block disposed on the bottom plate in the contacting terminal; an electric insulating cap member having an opening and disposed between the electric insulating block and the circumference of the printed circuit board, the electric insulating block fitted in the opening with the contacting piece protruding in the upper direction; and a fixing ring mounted in a chassis of the capsule support while pressing the circumference of the cap member to the printed circuit board.
