WO1995023434A1 - A piezoelectric audio transducer - …
https://patents.google.com/patent/WO1995023434A1/en
Piezoelectric audio transducers are known to comprise a piezoelectric bender and supporting structure. Typically, such a transducer has the piezoelectric bender attached to the housing in by the periphery of the bender to provide adequate acoustic impedance. With such a structure, the piezoelectric bender vibrates when it receives an electrical ...
