Piezo alarm or buzzers are simple devices that can generate basic beeps and tones.
They work by using a piezo crystal, a special material that changes shape when voltage is applied to it.
If the crystal pushes against a diaphragm, like a tiny speaker cone, it can generate a pressure wave which the human ear picks up as sound.
