Condenser microphone and its output connector

An output connector for a condenser microphone, in which

• a first pin for earthing and second and third pins for signal are penetratingly provided in a connector base consisting of an electrical insulator;
• the output connector is mounted in an end portion of a microphone casing in a state in which the first pin is electrically connected to the microphone casing;
• the output connector includes a printed wiring board, which is arranged on the base inner surface side of the connector base and through which the pins are inserted, and a shield cover, which is arranged on the base inner surface side so as to cover the printed wiring board and through which the pins are inserted;
• and
• the printed wiring board is a double-sided board, on the board upper surface side facing the shield cover, a capacitor element for preventing intrusion of high-frequency waves and a Zener diode element for preventing circuit destruction due to static electricity are mounted in parallel between the first pin and the second pin and between the first pin and the third pin, and on the board lower surface side, an electrostatic shield layer consisting of a copper foil which does not connect electrically with the second and third pins and connect electrically with the first pin is formed, wherein
• between the base inner surface side of the connector base and the electrostatic shield layer of the printed wiring board, a magnetic sheet having pin insertion holes for the pins are disposed throughout almost entire surfaces therebetween.
