Types of Buzzers
Active Buzzer
An active buzzer has a built-in oscillator, allowing it to produce sound when powered with a DC voltage. It is simple to use and does not require an external signal.
-
Features:
- Built-in oscillator
- Produces a fixed tone
- Easy to use (plug-and-play)
- Requires only DC voltage to operate
-
Applications:
- Alarms
- Timers
- Simple sound notifications
Passive Buzzer
A passive buzzer requires an external oscillating signal to produce sound. It offers more flexibility, allowing you to control the tone and frequency.
-
Features:
- Requires an external signal (e.g., square wave)
- Fully customizable sound (tone, frequency, duration)
- Controlled via microcontrollers or signal generators
-
Applications:
- Musical projects
- Custom sound patterns
- Advanced sound notifications
