Piezo Buzzer (Big) 6-12V

6-12V Piezo Buzzer (Big)

Looking for a reliable and budget-friendly buzzer for your electronics projects? This 6-12V Piezo Buzzer is a perfect solution for experiments or applications that require a clear and loud audible alert—ideal for use as a doorbell, alarm, or buzzer in DIY electronics.

Product Overview:

The piezo buzzer operates on a 6V to 12V DC power supply, making it compatible with standard 6V or 9V batteries. Its lightweight, durable plastic shell and simple internal construction offer consistent performance at a low cost.

At the heart of this buzzer is a piezoceramic disc, a manmade material known for its strong piezoelectric properties. When subjected to an alternating electrical signal, the disc rapidly deforms, generating sound through vibration. This is the reverse piezoelectric effect, which is the foundation of how piezo buzzers operate.

Why Choose This Buzzer?

Whether you're building a sensor-based alert system, an IoT device, or a reversing signal for a vehicle, this buzzer delivers loud, reliable sound output while maintaining energy efficiency and longevity.
