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 ...
While technological advancements have caused buzzers to be impractical and undesirable [citation needed], there are still instances in which buzzers and similar circuits may be used. Present day applications include: Novelty uses; Judging panels; Educational purposes
The driver ADP3418 chip (bottom left), used for driving high-power field transistors in voltage converters. Above it is seen next to such a transistor (06N03LA), probably driven by that driver. In electronics , a driver is a circuit or component used to control another circuit or component, such as a high-power transistor , liquid crystal ...
Simple Pierce oscillator. The Pierce oscillator is a type of electronic oscillator particularly well-suited for use in piezoelectric crystal oscillator circuits. Named for its inventor, George W. Pierce (1872–1956), [1] [2] the Pierce oscillator is a derivative of the Colpitts oscillator.
Figure 2. Schematic symbol and circuit incorporating the mechanical–electrical analogy for a piezoelectric sensor. Figure 2's detailed model includes the effects of the sensor's mechanical construction and other non-idealities. [12] The inductance L m is due to the seismic mass and inertia of the sensor itself.

A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
A resistor removed from a high voltage tube circuit shows damage from voltaic arcing on the resistive metal oxide layer. Resistors can fail open or short, alongside their value changing under environmental conditions and outside performance limits. Examples of resistor failures include: Manufacturing defects causing intermittent problems.
