ABSTRACT:
A piezoelectric electroacoustic transducer is miniaturized and has a reduced frequency, and even when a diaphragm has a warp or winding, the resonance frequency is be stabilized. The piezoelectric electroacoustic transducer includes a substantially rectangular piezoelectric diaphragm flexurally vibrating in a thickness direction in response to the application of an alternating signal between electrodes and a casing for accommodating the piezoelectric diaphragm, wherein the casing is provided with supporting members for supporting four corners of the piezoelectric diaphragm.
