How does a buzzer work in a building
When a voltage is applied across the two electrodes, the piezoelectric material mechanically deforms due to the applied voltage. This movement of the piezo disk within the buzzer creates sound in a similar manner as the movement of the ferromagnetic disk in a magnetic buzzer or the speaker cone mentioned above.
How does a door buzzer work
In a buzzer, the simplest sort of doorbell, an electromagnet is used to operate a self-interrupting circuit. When the circuit is closed, the electromagnet is magnetized so it pulls up on the contact arm. This breaks the doorbell circuit, which shuts off the electromagnet.

How do you tell if a buzzer is active or passive
Active buzzers are called active because they only need a DC voltage to produce sound. Passive buzzers need an AC voltage to produce sound. An easy way to tell active and passive buzzers apart is by connecting them to a DC voltage source like a 9 volt battery.
