Multilayer piezoelectric speaker

 piezoelectric speaker which transforms mutually using piezoelectric ceramics's piezoelectric effect and the electrical energy mechanical energy, for pastes attaches on the plate diaphragm the piezoelectric ceramics thin film oscillator input audio frequency voltage signal, causes the ceramic thin film oscillator to have the expansion vibration, thus leads the plate diaphragm to have the machinery bending vibrations which corresponds with the input tonic train signaling intensity and the frequency to promote the air sound production
