发明名称 Piezoelectric transducers
摘要 The invention consists of an integral transducer for a sound radiating diaphragm which may consist of a piezoelectric material, a substrate or a spacer and electrical connector means for a wire harness or other electrical connection. The substrate is used to enhance the motion of the piezoelectric element by spacing the piezoelectric element from the diaphragm. The substrate is larger in area than the piezoelectric element. The transducer system acts to impart motion to a diaphragm. The transducer comprises a piezoelectric element subject to displacement by applied electric potential that has a top side, an under side and an outer perimeter; a substrate that is joined to the underside of the piezoelectric element, and means to apply electric potential to the piezoelectric element.
