Abstract
Official abstract text for this publication.
A method for driving a condenser microphone is provided. The condenser microphone comprises a membrane and an electrode constituting a capacity. A polarization voltage is applied between the membrane and the electrode. According to the method, an electrical signal generated by the condenser microphone based on a received acoustic signal causing a deflection of the membrane) is detected, and the polarization voltage is varied in response to the detected electrical signal.
