Abstract

PURPOSE:To eliminate split oscillation, by arranging piezoelectric elements in positions, which are intersections of nodes of the oscillation mode of the plane diaphragm and are symmetrical for the center point, to oscillate the diaphragm at multiple points. CONSTITUTION:A glass plate is used as plane diaphragm 1, and piezoelectric elements 4 are fitted to respective driving positions by adhesion, and rubber 5 which performs Q drum with the suspension of the glass plate is stuck, and hard board 6 for fitting to the cabinet is mounted on the back of rubber 5. Piezoelectric elements 4 are molded by resin 7 as required. The connection method of four piezoelectric elements 4 is so adopted that they are driven in the same phase.
