Abstract:
1. A microphone assembly comprising: a microphone housing having a sound inlet port; disposed inside the housing, a transducer element adapted to provide a transducer signal in response to incoming sound received at the sound inlet port; a magnetically activated element disposed inside the microphone housing; the housing including a first externally accessible terminal for receiving a signal from a first external input signal source; and the housing including a second externally accessible terminal providing an output signal, the magnetically activated element being operatively coupled to the transducer signal, to the first input signal source via the first externally accessible terminal, and to the second externally accessible terminal, and being operative to selectively route the transducer signal or the input from the first external input signal source as the output signal to the second externally accessible terminal based on a presence or a field strength of a static magnetic field applied to the magnetically activated element.
