Claim 6:
7. The MEMS condenser microphone as described in claim 5, wherein the electrostatic clutch further comprises a fifth connecting part, a first suspension beam and a first suspension plate acting as both the stator part of the electrostatic clutch and rotor part of the capacitive sense structure;
the fifth connecting part comprises an end connected to the connecting rod, and another end connected to the multiple arrays of HIN electrodes;
two ends of the first suspension plate are suspended and supported in the vacuum cavity by means of the first suspension beam, the multiple arrays of biased electrodes are arranged on the first suspension plate and spaced from each other; first gaps and second gaps are formed in the first suspension plate at two opposite sides of the multiple arrays of biased electrodes;
the multiple arrays of HIN electrodes one-to-one correspond to and extend into the first gaps; and
the capacitive sensing structure comprises third sensing static electrodes arranged on the base plate and spaced from each other, and the third sensing static electrodes one-to-one correspond to and extend into the second gaps.
