Microphone

A microphone has a housing (9) defining an acoustic hole (99) and having inner faces. The microphone includes a MEMS capacitor (1) secured to and electrically connected with a first face (6) of the inner faces of the housing (9), the first face defining the acoustic hole (99), a detecting circuit (7...

Beschreibung
Zusammenfassung:	A microphone has a housing (9) defining an acoustic hole (99) and having inner faces. The microphone includes a MEMS capacitor (1) secured to and electrically connected with a first face (6) of the inner faces of the housing (9), the first face defining the acoustic hole (99), a detecting circuit (7) secured to and electrically connected with a second face (8) of the inner faces of the housing (9), the second face (8) being not adjacent the first face (6), the detecting circuit (7) detecting at least a change in the electrostatic capacity of the MEMS capacitor (1). The microphone further includes a flexible substrate (4) secured to the first face (6) and the second face (8) and disposed under a bent state inside the housing (9). The flexible substrate (4) establishes electrical connection between the MEMS capacitor (1) and the detecting circuit (7) via a wire electrically connecting the first face (6) and the second face (8).
