ABSTRACT:
A piezoelectric speaker is manufactured by processing a plate to form a frame, a plurality of vibrating plates and a plurality of dampers. The plurality of dampers are connected to the frame and the plurality of vibrating plates so that each of the plurality of vibrating plates linearly vibrates. At least one piezoelectric element is arranged on the plurality of vibrating plates. An edge is formed for preventing air from leaking through a gap among the plurality of vibrating plates, the plurality of dampers, and the frame.
