ABSTRACT:
A microphone has a diaphragm which vibrates in response to sound waves and a proximately positioned charge carrying circuit for dynamically controlling a compliance of the diaphragm. A micromachined microphone has a substrate, a compliant silicon membrane, and a charge carrying circuit positioned between the substrate and the membrane. A charge applied to the charge carrying circuit controls the compliance of the membrane thereby controlling operating characteristics of the microphone, such as dynamic range and frequency response.
