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. The buzzer is represented by the letter "H" or "ha" in the circuit (the old standard used "FM", "LB", "JD", etc.). There is no vibration source inside the passive buzzer, so it can't sound with DC signal. It must be driven by 2K ~ 5K square wave. In some special cases, a control port can be multiplexed with LED.
