Abstract

A complex of piezoelectric ceramics comprises a top-layer ceramic sheet, a bottom-layer ceramic sheet and at least one middle-layer ceramic sheet. Those sheets are made by piled each other and fritted. Thereof, each joint surface between each ceramic sheet is coated with an alloy layer of silver and Pd, and each outside surface of the top-layer ceramic sheet and the bottom-layer ceramic sheet is coated with silver layer respectively, so as to form a conductive return circuit in the complex. The complex can be combined on a side surface of a metal board, and then be installed in a seat body of supplying positive and negative electrical signals, so as to make up a piezoelectric exciter, a piezoelectric loudspeaker or a piezoelectric buzzer.
