Abstract
A sound producing package structure includes a plurality of chips disposed within a cavity. The chips includes a first chip and a second chip, the first chip includes a first sound producing membrane and a first actuator attached to the first sound producing membrane, and a second chip includes a second sound producing membrane and a second actuator attached to the second sound producing membrane. The first sound producing membrane and the second sound producing membrane are actuated toward a center of the cavity in a synchronous fashion so as to produce a sound pressure.
