Součásti bzučáků, piezoelektrické reproduktory

Buzzer element products, also known as "benders," are composed of two conductive electrodes sandwiching a piezoelectric material, which exhibits a mechanical deflection when subject to an electric field; or conversely produces an electrical signal when subject to mechanical strain. Products of this type are primarily used to form compact audio signaling devices, often by attachment to the wall of a device's enclosure, which aids transmission of the vibrations produced by applying an electrical signal to the buzzer element into the surrounding air.
