A piezoelectric transducer converts mechanical force into electrical output. This is made up of Quartz crystal which contains SiO2. Piezoelectric crystals are electrically neutral. The atoms inside the crystals in an unsymmetrical manner but their electric charges balanced

When the force is applied to stretch or bend it, an electric voltage is generated. If there is no stress, no charges are induced. When there is stress, positive charges are induced on one side and negative charges induced on the opposite side. Compression occurs in the crystal as the force is applied.

Features

1. Clear sound
2. Ultra-thin and lightweight
3. No contacts: therefore, no noise and highly reliable
4. Low power consumption for voltage type
5. Excellent accessory for acoustic instrument pickups, stompboxes, contact mics, etc.
6. Piezoelectric buzzer film. Can be fitted to used acoustic guitars, CBGs, drums, etc.
7. 27mm brass outer diameter plate and ceramic inner diameter plate.
8. All the discs are made from selected copper, ensuring excellent conductivity and long-lasting use.

Specifications:

1. Thickness: 3.36mm
2. Diameter: 15mm

6. Sound pressure level: 85DB 10cm
7. The input voltage: 30vp-p max
8. Operating Temperature: -20~70
9. Storage Temperature: -30-80

Applications:

1. Used in Medical Diagnostics
2. Electric lighter
3. Microphones.

Package Include:

This is a pack of 1 piezoelectric elements, pre-wired with leads to save you having to solder the leads on yourself. 50mm is a perfect size for installing in cigar box guitars, foot stompers and other home-made instruments. They can also be used for custom pickup arrangements in more traditional stringed and percussion instruments. An electric pick-up is a sure-fire way to take your cigar box guitar or another build to the NEXT LEVEL, and many builders report that their instruments are much more attractive to potential buyers if they include a pickup.

Features:

1. Great for Acoustic Guitar Pickups, drum triggers & more!
2. 50mm outside diameter with pre-soldered 2-inch leads
3. High-quality 
4. Great for Cigar Box Guitars

Package Includes:

1 x Piezo buzzer 50mm (Pack of 1)
