Abstract: There are provided a microphone stand having a connector supporting groove, and a microphone body supported by the microphone stand as a result of insertion of a connector case into the connector supporting groove. A resilient conductive cloth which comes into contact with the connector case is arranged in the connector supporting groove, with the connector case inserted in the connector supporting groove. The conductive cloth is preferably arranged in a ring shape along a lower bottom portion of the annularly formed connector supporting groove. This configuration mitigates rattling generated between the connector supporting groove and the connector case, thereby suppressing generation of a vibration noise due to microphone shaking.

Abstract: A microphone includes a volume reduction filling member therein. The volume reduction filling member includes an elastic body having an insertion hole for inserting an electrode extraction member which extracts a generated current to a back end side by contacting a front end side thereof to a fixed electrode of a microphone unit, and reducing a volume inside a unit case. The elastic body is divided into a tip-side main body portion and a base-end-side flexible flange portion through a circular groove around the insertion hole from an outer peripheral face side of a base end portion thereof. When an outer peripheral edge portion of the base-end-side flexible flange portion receives an equal pressure toward a tip direction so as to bend, the elastic body concentrates a stress into a front portion side of the insertion hole through the tip-side main body portion.
