PROBLEM TO BE SOLVED: To allow for easy diversion of a model with an output switch of audio signal to a model with no switch, while increasing the rear air chamber of a microphone unit.SOLUTION: A reed switch is used as an output switch of audio signal for controlling an audio signal from a microphone unit 1 on/off, and the reed switch is arranged at the output connector 11 portion of a microphone case 6. A magnet 22 is arranged on a connector cover 21 surrounding the output connector, and on/off control is performed by the relative movement operation of the connector cover to the output connector. Consequently, it can be provided as a model with no switch always outputting an audio signal from the microphone unit 1, when the connector cover 21 is removed. |
