Abstract
The output connector for a condenser microphone has a circuit board mounted with a capacitor element and a shield cover having a first through hole, a second through hole, and a third through hole and covering the whole surface of the circuit board arranged in a state in which a first pin, a second pin, and a third pin are inserted through the first through hole, the second through hole, and the third through hole respectively, and the shield cover has a non-conducting magnetic sheet having a first insertion hole, a second insertion hole, and a third insertion hole through which the first pin, the second pin, and the third pin are also inserted respectively, on at least one of an outer surface and an inner surface of the shield cover.
Claims7
An output connector for a condenser microphone which is mounted in an end portion in a microphone casing of the condenser microphone, the output connector comprising:
- a microphone casing;
- a connector base comprising an electrical insulator, present in the microphone casing;
- a first pin for earthing, and a second pin and a third pin for signals penetratingly provided on the connector base;
- a circuit board mounted with a capacitor element for high-frequency current bypass connected between the first pin and the second pin and the third pin in an inner surface side of the connector base located on an inside of the microphone casing;
- and
- a shield cover having a first through hole, a second through hole, and a third through hole and covering a whole surface of the circuit board arranged in a state in which the first pin, the second pin, and the third pin are inserted through the first through hole, the second through hole, and the third through hole respectively,
- wherein the shield cover has a magnetic sheet having a first insertion hole, a second insertion hole, and a third insertion hole through which the first pin, the second pin, and the third pin are inserted respectively, on at least one of an outer surface and an inner surface of the shield cover,
- a diameter of the first through hole and a diameter of the first pin are substantially equal,
- diameters of the second through hole and the third through hole are larger than diameters of the second pin and the third pin respectively, and
- at least the second insertion hole and the third insertion hole are in close contact with outer peripheries of the second pin and the third pin respectively.
