6–15V Piezo Buzzer Alarm – 95dB Continuous Tone | 22mm
6–15V Piezo Buzzer Alarm – 95dB Continuous Tone | 22mm
6–15V Piezoelectric Buzzer Alarm with Mounting Holes
This compact piezoelectric buzzer alarm delivers a loud, continuous 95dB tone — making it an ideal audible indicator for DIY electronics projects, security systems, industrial control panels, Arduino builds, and more. Operating across a wide voltage range of 6V to 15V DC with a built-in drive circuit, it's ready to connect straight to your project without additional driver components.
With a slim 22mm diameter and two mounting holes spaced 30mm apart, this buzzer installs cleanly onto panels or enclosures. The 90mm lead wires give you enough length to route neatly inside your build. Made in Mainland China.

Frequently Asked Questions
Q: Does this piezo buzzer require an external driver circuit?
A: No — this piezoelectric buzzer alarm has a built-in drive circuit, so you can connect it directly to any DC power source between 6V and 15V and it will produce a continuous tone immediately. No additional components are needed.
Q: What voltage should I use to power this buzzer alarm?
A: The buzzer operates across a wide range of 6V to 15V DC, with a rated voltage of 12V DC. It draws a maximum of 10mA, making it highly energy-efficient and compatible with most microcontroller and embedded system power supplies.
Q: How loud is this piezo buzzer and what frequency does it emit?
A: This buzzer produces a 95dB continuous tone at a frequency of approximately 3,900 Hz (±500 Hz) — loud enough to serve as a clear audible indicator in noisy workshop or industrial environments.
