Piezoelectric speaker

A piezoelectric speaker is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to . Piezoelectric materials change shape when exposed to electric fields. By causing them to change shape at specific times, we can use them to . These piezoelectric speakers are the same sort responsible for the buzzing noise which emanates from your alarm clock, pedometer, or gameboy.

To show that when an alternating voltage is applied to a piezoelectric crystal the crystal vibrates in such a way that it may serve as an audio speaker. When the first and second electrodes include a layer mainly containing indium tin oxide, indium zinc oxide, or zinc oxide, the piezoelectric speaker can be made. With an impedance of over 4ohms at 1kHz, and above ohms at kHz, the piezo ceramic speaker presents no added load to the amplifier and rejects low . Piezo Source is the proprietary manufacturer of the Motorola bimorph piezo technology. You do not get very good quality noises from a piezoelectric speaker even if you have a good quality waveform to give it.
