Piezoelectric Acoustic Modules
R11 Receivers
Overview
Multilayerpiezoelectricbimorphactuatorsareceramic
elements used to convert electrical energy into mechanical
energysuchasdisplacementorforcebyutilizingthe
piezoelectric longitudinal effect.
KEMET’s piezoelectric acoustic module use multilayer
piezoelectricbimorphactuatorswhichareproducedbased
on our unique element structure design and piezoelectric
ceramic materials with high electrostrictive factors.
Thepiezoelectricacousticmodulegeneratesbothsound
andvibrationfromthechassissimultaneously.
Applications
• Smartphone Receiver
