Sound level: 100 dB

TDK’s piezoelectric buzzers are sounding bodies that use unimorph piezoelectric vibration plates and feature small sizes, low voltages, and loud sound volumes, as well as high performance and a design that allows for easy mounting on ...

Knowles is committed to advancing audio technology and enabling differentiated performance. Our proven performance in acoustics and sub-miniature audio solutions uniquely positions us to develop superior solutions. These technologies ...

Knowles’ digital multi-mode ultrasonic microphone significantly improves ultrasonic SNR with our proprietary ultrasonic boost technology, enabling easier integration for precision applications. Digital microphones reduce the number of ...

Built on our CMOS/MEMS technology platform (originally launched in 2002), the SiSonic™ silicon-based microphone series is entering its fourth generation of development, with product shipments exceeding 5 billion units to date. The proven ...

Sound level: 0 dB - 94 dB

Piezoelectric Buzzer is a self drive type piezoelectric sounder with built-in oscillation circuit transistor and resistors. It generates consistent single tone sound just by applying D.C.voltage. Using a suitably designed resonant system, ...

MEMS microphones can review all audio needs where size and quality are important. This is based off of Omrons sensor controls and uses price points created by electret condenser microphones to work with care. They also work with reliable ...

The RO: Buzzers sre designed for maximum control and command of electrical circuits, providing a 70 dBA sound level and 230 supply voltage in 8 at 12 VAC. Combining simplicity with optimum flexibility, robustness and comprehensible product ...
