Buzzer is an electronic buzzer with integrated structure, which is powered by DC voltage. It is widely used as a sound device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and so on. There is no shock source inside the passive buzzer, so if it cannot be buzzed by DC signal, it must be driven by 2K ~ 5K square wave. The buzzer horn can be used either as a passive buzzer or as a horn. When the passive buzzer is used, it can produce a variety of sound frequencies and music through Arduino programming. When the horn is used, it can produce and play music in combination with mini mp3 module.
