    摘要: A condenser microphone includes a unidirectional microphone unit including a cylindrical metallic unit case having a front audio terminal on a front surface and a rear audio terminal on a side surface; an acoustoelectric converter having a diaphragm and a backplate, disposed in the metallic unit case; and a metal mesh covering a rear audio terminal from an inside of the unit case. A coil spring having an outside diameter larger than an inside diameter of the unit case is disposed in the unit case to thereby press the metal mesh against the inner wall surface of the unit case to contact the metal mesh with the unit case.
