A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and ...
Animal Jam Classic, [1] formerly known as Animal Jam, is a massively multiplayer online game developed by WildWorks and recommended for kids up to the age of 12. It was launched in 2010, in collaboration with the National Geographic Society . [ 2 ]
The piezoelectric pickup contains a piezo crystal, which converts the vibrations directly to a changing voltage. Many semi-acoustic and acoustic guitars, and some electric guitars and basses, have been fitted with piezoelectric pickups instead of, or in addition to, magnetic pickups.
A tweeter or treble speaker is a special type of loudspeaker (usually dome, inverse dome or horn-type) that is designed to produce high audio frequencies, typically from 2,000 to 20,000 Hz. The name is derived from the high pitched sounds made by some birds (tweets), especially in contrast to the low woofs made by many dogs , after which low ...
Piezoelectric disk beeper. A piezoelectric element may be driven by an oscillating electronic circuit or other audio signal source, driven with a piezoelectric audio amplifier. Sounds commonly used to indicate that a button has been pressed are a click, a ring or a beep.

Contact microphones based on piezoelectric materials are passive and high-impedance, and they sound tinny without a matching preamp. Instead of being used as a microphone, they alternatively may be used to produce sound (typical used as the buzzer in computer motherboards ) by sending voltages to them.
Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.
