<p><P>PROBLEM TO BE SOLVED: To provide a piezoelectric speaker for improving sound quality by suppressing a force applied from a lead wire preventing vibration of a piezoelectric vibrating plate, and by suppressing the force applied from the lead wire preventing the vibration of the piezoelectric vibrating plate. <P>SOLUTION: The piezoelectric speaker includes a piezoelectric material generating distortion caused by an applied electric signal, a piezoelectric vibrating plate closely contacting the piezoelectric material to convert the distortion into acoustic vibration, and an elastic body supporting the piezoelectric vibrating plate on a sounding body disposed on the outer circumference of the piezoelectric vibrating plate. In the above piezoelectric speaker, a film-shaped conductive path is provided between the piezoelectric vibrating plate and the elastic body, and wiring to the piezoelectric vibrating plate is performed via the end of the conductive path extending to the direction of a sounding plate. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
