KEMET Piezoelectric R11 Acoustic Module

KEMET Piezoelectric R11 Acoustic Module is designed to generate simultaneous sound and vibration from the chassis by utilizing the piezoelectric longitudinal effect to convert electrical energy into mechanical energy. The sound is generated from the panel surface, does not require any sound hole, and is audible even in noisy surroundings. The R11 module uses multilayer piezoelectric bimorph actuators, which are produced based on a unique element structure design and piezoelectric ceramic materials with high electrostrictive factors. This module features a flexible design, high reliability, and stable sound pressure. KEMET Piezoelectric R11 Acoustic Module is ideal for speakers and smartphone receivers.
