摘要:
A condenser microphone includes a volume restrictor disposed in a space inside a microphone case and an electronic circuit disposed in the space and encompassed by the volume restrictor. The volume restrictor reduces the volume of the space and prevents sound waves entering the space through openings on the microphone case from reaching the electronic circuit.
