Active Buzzer

The Active Buzzer is an electromagnetic audio signaling device that produces a continuous tone when supplied with DC voltage. Unlike passive buzzers, it does not require an external oscillating signal, making it extremely easy to use—simply connect power and it beeps. This module is ideal for adding audible alerts to DIY electronics, Arduino projects, security systems, and appliances. Key features include a compact design, low power consumption, and a sound output of ≥85dB at 10cm. It operates within a wide voltage range (typically 3.3V to 12V depending on the model), making it versatile for various applications. Choose this buzzer for reliable, hassle-free audio feedback in your circuits. It's a staple component for hobbyists, students, and engineers building prototypes or final products requiring simple sound indication.
