An easy way to distinguish between active and passive buzzers

The fundamental difference between active and passive buzzers is that the product requires different input signals.The ideal signal for active buzzers to work is direct current, usually marked as VDC, VDD, etc.Because there is a simple oscillation circuit inside the buzzer, constant dc current can be converted into a certain frequency of pulse signal, from the surface out of the magnetic field alternating, driving the sound of molybdenum plate vibration.However,Passive Piezo Buzzer some active buzzers can also work under certain ac signals, but the voltage and frequency of ac signals are very high,Piezoelectric Buzzer which is generally not adopted.Thin Piezo Buzzer
