Patent ID: 7801316

Claim:
A capacitor microphone comprising: a battery holder which is connected to a microphone unit housing at one end and is connected to a connector sleeve at the other end, the other end of the battery holder being circumferentially surrounded by the connector sleeve; an output connector housed in the connector sleeve, and detachably receiving a plug having a grounding sleeve for a microphone cable; a cylindrical conductive battery cover which is slidably movable in a direction along an axis of a longitudinal extension of the battery holder, between a position covering the battery holder and a position releasing the battery holder and is electrically connected to the microphone unit housing at the position covering the battery holder; and an elastic and conductive cloth which is present between the connector sleeve and the cylindrical conductive battery cover, and is in contact with the connector sleeve and the cylindrical conductive battery cover, the connector sleeve and the battery cover being electrically connected by the elastic and conductive cloth, the elastic and conductive cloth arranged such that during the slidable movement of the cylindrical conductive battery cover the electrical connection is maintained, wherein the elastic and conductive cloth is fitted into a groove on a peripheral surface of the connector sleeve, and is in contact with an inner surface of the battery cover.
