How to distinguish active and passive buzzer?

An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage.

A passive buzzer requires an AC signal to make a sound.

To identify them, if you apply a DC voltage to them and it buzzes, it's an active.


Advantages and disadvantages of piezo?

Advantages:They generate a voltage proportional to the velocity the crystal is deformed so require no local power source.

Disadvantages: They are high impedence and can pick up stray voltages in the connecting wires. The crystal is also prone to cracking if overstressed.
