Products＞Piezoelectric products＞Piezoelectric Busser/ Sounder
Piezoelectric diaphragm and piezoelectric buzzer / sounder are based on the flexural vibration of a diaphragm with a piezoelectric element and a metal plate bonded together.Our piezoelectric diaphragm and piezoelectric buzzer / sounder use piezoelectric elements using process technology such as our original piezoelectric ceramic material development technology / thin film technology, and we carry out integrated production from materials to finished products.
Technical data
| Characteristic | |
|---|---|
 |
・Clear electronic sound. Try the sound ・Current consumption is small. ・Compact and lightweight, can be mounted on a printed circuit board in a small space. ・Safety is high because there is no spark in the structure with no contacts inside. We have piezoelectric diaphragms, piezoelectric buzzers and sounders that meet various needs such as high sound pressure and wide sound range. Used in a wide range of fields, such as home appliances and office automation equipment that are required to be compact and lightweight, disaster prevention equipment that requires high volume and high reliability, etc. |
