A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. The buzzer is an integrated structure of electronic transducers, DC power supply, widely used in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers, and other electronic products for sound devices. Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.

The active buzzer has an internal oscillating source, and the buzzer will sound as soon as it is energized. The active buzzer is widely used in computers, printers, copiers, alarms, electronic toys, automotive electronics, telephones, timers, and other electronic products for sounding devices.

The simple way to distinguish passive buzzer and the active buzzer is to drive them with a battery. Connect positive and negative terminals properly with the battery, if the buzzer sounds, it is an active buzzer. If soundless, it is a passive buzzer.

TMB12A03 Active Buzzer [2.3KHz] beeps at a predefined frequency

(2300 ±300 Hz) on its own even when you just apply steady DC power. You can still produce a sound from the buzzer connected to a microcontroller, such as an Arduino, by just driving a standard high output on the connected pin, so you don't need to use processing power, hardware timers, or additional code to produce sound.
