よう構成してなる圧電型スピーカ。A slit passing through the plate material in the thickness direction is formed in a plate material with a relatively large acoustic internal loss, and a piezoelectric diaphragm is applied from the back side of the plate material to close the opening of the slit. Among the generated vibration components of the piezoelectric diaphragm, high-frequency vibration components are suppressed by the plate material, mid-range vibration components are converted into plane waves by the linear sound source action of the slits, and low-frequency vibration components are suppressed by the plate material. A piezoelectric speaker configured to transmit and radiate energy.
