Product Introduction:

The self-powered buzzer is a type of integrated-structure electronic buzzer that uses DC power supply. It is widely used in computers, printers, copiers, alarms, electronic toys, automotive electronics, telephones, timers, and other electronic products as a sound-emitting component.

Buzzers are mainly divided into piezoelectric buzzers and electromagnetic buzzers. In circuit diagrams, buzzers are typically represented by the letter “H” or “HA” (older standards may use “FM”, “LB”, “JD”, et c.).
