This 3V To 12V Piezo Active Buzzer works great for breadboarding projects since it fits right into a breadboard or paperboard. 3V To 12V Piezo Active Buzzer is a small 12mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces. This is not a true piezoelectric speaker but behaves similarly. Instead of a piezoelectric crystal that vibrates with an electric current, this tiny speaker uses an electromagnet to drive a thin metal sheet. That means you need to use some form of alternating current to get sound. The good news is that this speaker is tuned to respond best with a square wave (e.g. from a microcontroller).We have also 3 pins Passive Buzzer, Piezo Passive Buzzer, Piezo Buzzer Alarm Speaker, etc.

Features of 3V To 12V Piezo Active Buzzer:

• Piezo sounders contain a piezoelectric vibration plate (also known as a piezo element) within a molded case.
• Sound is emitted when a voltage is applied and the piezo element inside the case vibrates.
• Piezo buzzers generally use less current.
• Have a higher sound output and a wider operating voltage.
• Buzzers and Sounders can also be split into Audio Indicators and Audio Transducers.
