Universal LCD Digital Multimeter UNI-T UT51 - Red

The piezoelectric buzzer has a simple structure in which a ceramic piezoelectric disk is affixed to a vibrating plate. An alternative voltage applied to this element will cause a contraction or diametrical expansion of the element. This feature is used to fold a vibrating plate, which generates sounds. 2x Passive Buzzer 5V features:
