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 ...
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 ...

A buzzer or beeper is an audio signaling device, [1] which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices , timers , train and confirmation of user input such as a mouse click or keystroke.
The studio's flagship title was Animal Jam Classic (formerly "Animal Jam" before April 2020). [4] Animal Jam Classic is a virtual world for children, being developed within a partnership with the National Geographic Society. Users are placed in an online world called Jamaa, and are presented with a number of games, spaces to interract with ...
Pearl Jam blasted out their forthcoming album to a few hundred family, friends, industry insiders and reporters Wednesday, and the tracks showed they are doing anything but mellowing with age.
The use of thin film piezoelectric materials in electronics began in the early 1960s at Bell Telephone Laboratories/Bell Labs. Earlier piezoelectric crystals were developed and used as resonators in applications like oscillators with frequencies up to 100 MHz. Thinning was applied for increasing the resonance frequency of the crystals.
