Abstract
The present disclosure is of a piezoelectric speaker. The piezoelectric speaker includes a plurality of piezoelectric elements and a vibration transmission plate. Each piezoelectric element is configured to generate vibration based on an audio signal. The vibration transmission plate includes a plurality of elastic rods and a mass block, and each elastic rod connects the mass block and one of the plurality of piezoelectric elements. The mass block simultaneously receives the vibration of the plurality of piezoelectric elements and generates at least two resonance peaks in a frequency range of 20 Hz-40000 Hz.
