Abstract
In an embodiment, a piezoelectric speakerincludes a sheet memberand multiple piezoelectric vibration parts. The multiple piezoelectric vibration partseach have a vibration platesupported on the sheet memberin a vibratable manner, as well as a piezoelectric elementjoined to the vibration plate. In an embodiment, the piezoelectric speakerin combination with a dynamic speakerconstitutes an electroacoustic transducerL/R, and a pair of the electroacoustic transducersL,R constitute headphones. The piezoelectric speaker can improve sound pressures without lowering the resonance frequency.
