Abstract

An apparatus comprises a movable section for sound generation; at least one actuator configured to actuate the movable section, the actuator being in communication with electronic circuitry and configured to generate an acoustic signal substantially from the movable section when the at least one actuator is driven by an audio signal; and a back cover coupled to the movable section and configured to limit the generation of sound from the back cover by attenuating vibrations that are caused when the movable section is actuated by the at least one actuator. The movable section and the at least one actuator define a panel speaker.
