ABSTRACT:
An electroacoustic transducer having a piezoelectric element disposed on a diaphragm for converting an acoustic signal to an electric signal, and a differential amplifier for amplifying the electric signal. The piezoelectric element is connected between one of two input lines connected to the differential amplifier, and a reference voltage source. A load having substantially the same impedance as the piezoelectric element is connected between the reference voltage source and the other input line. The load may consist of another piezoelectric element.
