Abstract

See full text

This disclosure provides systems, methods and apparatus for microspeaker devices. In one aspect, a microspeaker element may include a deformable dielectric membrane that spans a speaker cavity. The deformable dielectric membrane can include a piezoactuator and a dielectric layer. Upon application of a driving signal to the piezoactuator, the dielectric layer can deflect, producing sound. In some implementations, an array of microspeaker elements can be encapsulated between a glass substrate and a cover glass. Sound generated by the microspeaker elements can be emitted through a speaker grill formed in the cover glass.
