PIEZOELECTRIC SPEAKER AND METHOD OF MANUFACTURING THE SAME

摘要

A piezoelectric speaker and a method of manufacturing the same that can obtain a high sound pressure using a piezoelectric thin film are provided. The piezoelectric speaker includes a piezoelectric thin film, electrodes formed on an upper surface or upper and lower surfaces of the piezoelectric thin film, a damping material layer formed on the lower surface of the piezoelectric thin film, and a frame attached around at least one of the piezoelectric thin film and the damping material layer using an adhesive.
