 Active Magnetic buzzer work is direct current signal, usually labeled VDC, VDD. Because a simple oscillation circuit inside the buzzer, It can be a constant DC converted into a certain frequency of pulse signal, from beyond the alternating magnetic field, surface drive molybdenum slice vibration pronunciation. But in some active buzzer can also work under specific ac signal, It has high request on the voltage and frequency of the AC signal .
