Electret condenser microphone
An electret condenser microphone includes a housing, a diaphragm disposed within the housing, first and second sound inlet ports and an acoustic resistive material disposed within the housing and in the acoustic path between the second inlet port and the diaphragm. The acoustic resistive may further electrically couple a backplate coupled to the diaphragm to an amplifier disposed within the housing.
