For an electric buzzer, it's electrical energy.
A hand buzzer typically operates on a low voltage of around 1.5 to 4.5 volts, which is not strong enough to cause harm or serious injury to someone. It is designed more for the surprising vibration effect rather than as a means of electric shock.

A buzzer works in an electric circuit by creating vibrations in a diaphragm when an electric current passes through a coil. The vibrations produce sound waves that we hear as a buzzing noise. By controlling the flow of current through the coil, the buzzer can produce different tones or patterns of sound.
Mechanical and sound energy.

In an electric buzzer, electrical energy is converted into mechanical energy. When the electric current passes through the buzzer's coils, it creates a magnetic field that causes a component, such as a diaphragm, to vibrate and produce sound. This transformation of energy allows the buzzer to produce a buzzing sound.
When you press the button, an electric current is connected, making a strong buzzing noise and/or light.
