Abstract
A Micromechanical Microphone is formed with a housing and a transducer therein. The housing has a sound inlet on one side of the transducer and a pressure compensation hole on the opposite side. A sealing diaphragm is placed on each side of the transducer to seal it against humidity, dust and dirt. The transducer may be a capacitive transducer with an external bias or an electret based transducer. The microphone is useful in small devices such as hearing aides.
