What type of device is a buzzer?
A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, train and confirmation of user input such as a mouse click or keystroke.
The flexible ferromagnetic disk is attracted to the coil when the magnetic field is activated, then returns to rest when the magnetic field is off. By oscillating the signal through the coil, the buzzer produces a fluctuating magnetic field, which vibrates the disk. This movement makes the buzzer sound.
These buzzers can be used alert a user of an event corresponding to a switching action, counter signal or sensor input. They are also used in alarm circuits. The buzzer produces a same noisy sound irrespective of the voltage variation applied to it. It consists of piezo crystals between two conductors.
In our first exploratory exercise we implement a buzzer, a simple actuator. The buzzer affects physical change in the external environment by introducing a sound which is controlled by the Arduino. The buzzer has two input pins labeled + and -. There is a metallic membrane inside the buzzer.

Buzzer is an electrical device that is used to get a buzzing or beeping sound when a potential difference is created or voltage is applied.
A piezo buzzer is modeled as a capacitor while a magnetic buzzer is modeled as a coil in series with a resistor. The frequency of the sound produced by both magnetic and piezo buzzers can be controlled over a wide range by the frequency of the signal driving the buzzer.
