ABSTRACT:
A superminiature microphone device includes a hollow body in the form of a decorative clothing accessory, a microphone unit including lead wires within the body, and a plug connected by the lead wires to the microphone unit wherein the plug has at least one pin-shaped terminal. A cord connector including a conical collet chuck is arranged to receive the pin-shaped terminal of the microphone unit plug from behind an article of clothing such as a necktie. A clamp member is arranged around the tip portion of the chuck for clamping the chuck about the plug terminal in response to a spring force. Accordingly, an electric cord can be routed from the connector behind the article of clothing so as to connect the microphone unit with an outside device so that the wearer's appearance is not affected by the presence of the connection cord.
