Abstract
A piezoelectric material composite membrane acoustic component with broadband and high sound quality comprises a vibrating membrane which is an electrically conductive membrane, a supporting frame having a hollow portion penetrating the supporting frame, a piezoelectric plat set including a first-piezoelectric-plate and a second-piezoelectric-plate formed on and electrically connected to the first-piezoelectric-plate and an AC power. A fixing portion of the vibrating membrane is fixed by the supporting frame. Each of the first-piezoelectric-plate and the second-piezoelectric-plate includes a top-electrode-layer, a piezoelectric-layer and a bottom-electrode-layer. The bottom-electrode-layer of the first-piezoelectric-plate is fixed on and electrically connected to a piezoelectric-plate fixing portion of the vibrating membrane. A spacing portion of the vibrating membrane is between the fixing portion and the piezoelectric-plate fixing portion. The AC power includes a first electrode and a second electrode electrically connected to the top-electrode-layer of the first-piezoelectric-plate and the vibrating membrane, respectively.
