Claim 0:
1. A micro-speaker device comprising:
a movable diaphragm device comprising a thickness of silicon or graphene material having a thickness 0.1 nm to fifty microns, the movable diaphragm device having a first surface and a second surface opposite of the first surface;
a shaft device having a first end and a second end, the first end coupled to the second surface;
an actuator device coupled to the second end and configured to drive the shaft device in a piston action to pull and push the movable diaphragm;
a housing enclosing the movable diaphragm device, the shaft device, and the actuator device;
a vented enclosure opposite of the movable diaphragm device and having one or more vent openings to allow air to move in and out of the one or more vent openings to generate a sound pressure signal; and
an electrode device coupled to the actuator device to initiate movement of the actuator device in a first direction and a second direction.
