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
