发明名称 PIEZOELECTRIC TRANSDUCERS
摘要 The invention consists of a piezoelectric material (11), a substrate or spacer (12) and an electrical connector means (13) for a wire harness or other electrical connection. The substrate (12) is used to enhance the motion of the piezoelectric element (11) by spacing the piezoelectric element (11) from the diaphragm. The substrate (12) is larger in area than the piezoelectric element (11). The transducer system (10) acts to impart motion to the diaphragm. The transducer (10) comprises a piezoelectric element (11) subject to displacement by applied electric potential (13) that has a top side, an underside and an outer perimeter. The substrate (12) is joined to the underside of the piezoelectric element (11). A means (15) applies electric potential to the piezoelectric element (11).
