Piezoelectric Acoustic Modules

R11 Receivers

Overview

Multilayerpiezoelectricbimorphactuatorsareceramic

elements used to convert electrical energy into mechanical

energysuchasdisplacementorforcebyutilizingthe

piezoelectric longitudinal effect.

KEMET’s piezoelectric acoustic module use multilayer

piezoelectricbimorphactuatorswhichareproducedbased

on our unique element structure design and piezoelectric

ceramic materials with high electrostrictive factors.

Thepiezoelectricacousticmodulegeneratesbothsound

andvibrationfromthechassissimultaneously.

Applications

• Smartphone Receiver

• Speaker
