Product Details

A piezo loudspeaker is an electro-acoustic component that utilizes the inverse piezoelectric effect to generate sound. It is composed of a piezoelectric vibration part and its packaging housing. In applications that involve enclosure designs, the piezoelectric speaker is composed of a piezo vibration part and its supporting frames. The vibration part of a piezoelectric loudspeaker generally consists of a metal diaphragm and a conjoined multilayer ceramic transducer (MLCTTM ).

MLCTTM has the characteristics of low driving voltage, high output power, and high structural stability. Therefore, piezoelectric loudspeakers are best for electronic devices which have a strict standard for product reliability, space restriction, and power consumption.

 

Features:

- Board output frequency, integration of MLCTTM component ensured a higher sensitivity than traditional piezo buzzer.
- Ultra-thin design, suitable for wearable and remote devices
- High reliability and safety insurance, piezo diaphragm neither generates nor receives EMF interference
- High relative electric-acoustic conversion rate
