The 6-12V Piezo Buzzer (Big) is an active piezoelectric buzzer designed to produce a clear, audible single-tone alert when supplied with DC voltage. Its compact wired plastic housing and simple operation make it suitable for alarm circuits, DIY electronics projects, Arduino-based projects, security systems, doorbells, sensor alerts and other applications that require an audible indication.
With a 6V to 12V operating voltage and 2.8 kHz frequency, this buzzer is easy to integrate into electronic circuits where a reliable audible warning or notification is required. It is a practical choice for students, hobbyists, makers and electronics developers looking for a big piezo buzzer for projects and alarm applications.
Whether you need a 12V buzzer for an alarm, a piezo buzzer for an electronics project, or a buzzer for sensor-based alerts, this model offers a simple and economical solution.

A buzzer, also known as a beeper, is a type of audio signalling device that can be mechanical, electromechanical, or piezoelectric (piezo for short). Alarm devices, timers, train and confirmation of user input such as a mouse click or keystroke are common applications for buzzers and beepers.
A buzzer, also known as a beeper, is a sound-producing output device. Because of its light weight, simple construction, and low cost, it can be used in a variety of applications such as car/truck reversing indicators, computers, call bells, and so on.
The Mini buzzers are usually of 2 types. It could be piezo buzzers or magnetic buzzers. There are many other classifications of buzzer. The buzzer can be in two types – Active Buzzer and Passive Buzzer.
Piezoelectric buzzers differ from magnetic buzzers in that they are driven by voltage rather than current. Piezoelectric buzzers are modeled as capacitors and magnetic buzzers are modeled as coils in series with resistors. If loudness is a key requirement, piezoelectric buzzers can usually produce higher pitched tones than magnetic buzzers.
Not directly at 12V. Use a transistor or relay module so Arduino switches the buzzer on and off while the buzzer gets 6 to 12V.
