Method of manufacturing a piezoelectric speaker
Abstract:
A method of manufacturing a piezoelectric speaker comprises forming a piezoelectric thin film and then forming an upper electrode and a lower electrode on and beneath the piezoelectric thin film, respectively, forming a damping material layer for attachment of the piezoelectric thin film below the piezoelectric thin film with the upper and lower electrodes formed thereon and therebeneath, attaching the piezoelectric thin film to an acoustic diaphragm in an inclined structure in which the piezoelectric thin film is horizontally turned from the acoustic diaphragm, and performing drying at room temperature; and fixing the acoustic diaphragm to a frame using an adhesive material with high elasticity.
