PROBLEM TO BE SOLVED: To provide a piezoelectric electroacoustic transducer that has compatibility in downsizing and a low frequency configuration and can stabilize the resonance frequency even when a bent or a swell exists in the diaphragm. SOLUTION: In the piezoelectric electroacoustic transducer provided with a square piezoelectric diaphragm 1 that is subjected to bending vibration in a broadwise direction by applying an alternating signal between electrodes and with cases 10, 20 that contain the piezoelectric diaphragm 1, supports 10 g are provided to the cases 10, 20 to support four corners of the piezoelectric diaphragm 1. |
