{wiki=Piezoelectric_speaker}
A piezoelectric speaker is a type of speaker that utilizes the piezoelectric effect to convert electrical energy into mechanical vibrations, producing sound. The piezoelectric effect refers to the ability of certain materials (typically specific ceramics or crystals) to produce an electrical charge in response to applied mechanical stress and vice versa. \#\#\# Key Features of Piezoelectric Speakers: 1. **Construction**: Piezoelectric speakers typically consist of a piezoelectric ceramic or crystal element that is bonded to a diaphragm.
