Abstract
The present invention provides a sound device, which includes a bottom plate, a support fixed to the bottom plate, a frame arranged on the support, and a diaphragm fixed to the frame. The sound device further includes a first piezoelectric ceramic sheet and a second piezoelectric ceramic sheet that are disposed separately on the support, and the first piezoelectric ceramic sheet and the second piezoelectric ceramic sheet are respectively provided with a transmission member abutting against the diaphragm. The sound device in the present disclosure can increase a driving force, increase a vibration amplitude, enhance a product sensitivity, broaden a response range, increase a driving fulcrum, improve a vibration balance, and avoid a product distortion.
