Abstract

PURPOSE:To improve the high sound band and extend the frequency band and simplify the production of a speaker, by fitting a piezoelectric transducer onto a vibration diaphragm molded with resin together with a frame as one body. CONSTITUTION:A frame 10 and a vibration diaphragm 11 are molded with resin as one body. A piezoelectric tranducer 12 is fixed to the approximate center of the diaphragm 11 by an adhesive. In the piezoelectric transducer 12, electrodes 12b and 12c are provided on both faces of a piezoelectric procelain plate 12a, and lead wires are connected to the folded part of the electrode 12b and the electrode 12c. When a signal is applied to these lead wires, the piezoelectric transducer 12 vibrates in both directions, and the piezoelectric transducer 12 and the diaphragm 11 fixed to it bend and vibrate as one body to generate acoustic waves.
