Abstract

PURPOSE:To decrease the number of elements and to improve the directivity, by contacting the first resonator to one end of piezoelectric element and contacting the second resonator of flat shape to another end. CONSTITUTION:A through-hole 12 is formed to a disc shape piezoelectric element 11, and electrodes 13, 14 are formed at the both ends. Two elements 11 are located via an adhesive 15 resonators 16, 17 are located at the external end via the electrode 13 and the adhesives 15. The resonators 16, 17 are bonded with the screw threads 19, 20 and adhesives 15. Accordingly, the number of piezoelectric elements is made less and the sound radiation surface is constituted by using the resonator 16, allowing low cost constitution as a whole.
