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.
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 piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated) A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo-is Greek for 'press' or 'squeeze'. [1]
The introduced piezoelectric field is perpendicular to electron transport direction, just like applying a gate voltage in the traditional field-effect transistor. Thus the electron transport properties will also be changed. [10] The materials for piezotronics should be piezoelectric semiconductors, [10] such as ZnO, GaN and InN.
Integrated Electronics Piezo-Electric (IEPE) characterises a technical standard for piezoelectric sensors which contain built-in impedance conversion electronics. IEPE sensors are used to measure acceleration, force or pressure. Measurement microphones also apply the IEPE standard. Other proprietary names for the same principle are ICP, CCLD ...

[15] [7] [16] A buzzer is also included [17] for simple audio feedback. A microUSB port is used to connect the console with computers, as well as to support the Thumby link cable. [ 7 ] This port is also used to charge the lithium polymer battery , which provides about 2 hours of operational runtime with a capacity of 40 mAh.
The white, round structure at the upper left is the piezoelectric horn that produces the alarm sound. An americium container from a smoke detector An ionization smoke detector uses a radioisotope , typically americium-241 , to ionize air; a difference due to smoke is detected and an alarm is generated.
