EA002 Electrostatic Actuator & Power

EA002 is especially designed for testing the frequency response of 1" microphones. It can be placed directly on the diaphragm of a microphone. It also could be used for 1/2" and 1/4" microphones with the corresponding adaptor.

EA002 is an electrostatic actuator designed and manufactured by BSWA for testing frequency response of microphones. An electrostatic actuator comprises an electric metal plate which can be placed near the microphone diaphragm. A time-various voltage is applied in between the metal plate and the diaphragm and thus an electrostatic force simulating sound pressure can be distributed on the diaphragm surface.

EA002 conforms to IEC 61094-6 standard and can be calibrated periodically with a sound level meter in accordance with IEC 61672-3 standard.
