LOUDSPEAKER WITH PIEZOELECTRIC ELEMENTS

摘要

Disclosed according to embodiments of the present invention is a loudspeaker operated by one or more piezoelectric actuator. The loudspeaker comprises a support structure; and a piezoelectric stacked cantilever-shaped actuator attached on the support structure through at least two grips. Moreover, the support structure includes a membrane suspended on the piezoelectric actuator, and contacts with the piezoelectric actuator between at least two grips.
