摘要： A microphone includes a microphone unit having a diaphragm vibrating in response to sound. The microphone unit converts the sound into an electrical signal. A cylindrical casing contains the microphone unit. A metal mesh strip rounded along the inner surface of the casing is attached to the inner surface of the main wall of the casing so as to cover openings. The rounded metal mesh strip has a spring portion generating spring force to expand the metal mesh strip against the inner surface of the casing to provide electrostatic shielding.
