Abstract
A condenser microphone that provides a balanced output of audio signals from initial steps of a diaphragm and a fixed electrode is provided. The condenser microphone includes: a condenser microphone unit including a diaphragm being arranged opposite a fixed electrode; a first impedance converter being connected to the fixed electrode of the condenser microphone unit and outputting a first electric signal generated in the fixed electrode; and a second impedance converter being connected to the diaphragm of the condenser microphone unit and outputting a second electric signal generated in the diaphragm. By this structure, balanced outputs of the audio signals having phases reverse to each other are provided by the first and second impedance converters immediately after the condenser microphone unit.
