A buzzer module is an electronic component used to generate sound. It typically consists of a piezoelectric or electromagnetic buzzer, which converts electrical signals into audible tones. The module can operate in either active or passive modes:

1.Active Buzzer: Contains an internal oscillator that generates sound when powered by a DC voltage. It continuously emits a tone without needing an external signal.

2.Passive Buzzer: Lacks an internal oscillator and requires an external signal, such as a square wave from a microcontroller, to produce sound.

2.Passive Buzzer: Lacks an internal oscillator and requires an external signal, such as a square wave from a microcontroller, to produce sound.

Working Principle:

The working principle of the passive buzzer module is based on the piezoelectric effect. When an electrical signal is applied to the buzzer, it causes a piezoelectric crystal inside the buzzer to vibrate at a specific frequency. This vibration produces sound waves that we can hear. The frequency of the sound produced by the buzzer depends on the frequency of the electrical signal applied to it. By changing the frequency of the signal, we can change the pitch of the sound produced by the buzzer.

Specifications:

1. Operating Voltage : 1.5 ~ 15V DC.

2. Working Current: Less than 25mA.

3. Tone Generation Range : 1.5 ~ 2.5kHz.
