Claim 15:
16. A micro speaker device comprising:
a movable diaphragm device comprising essentially of a first silicon material, and configured using the first silicon material to generate a variable pressure to output an acoustic signal;
a free standing peripheral region provided in the movable diaphragm device;
an actuator device configured from a second silicon material and coupled to the movable diaphragm device using a shaft device;
an electrode device operably coupled to the actuator device and configured to electrostatically move the actuator device;
a third silicon material coupled to the electrode device;
a housing comprising an inner housing region to enclose the movable diaphragm device, the actuator device, and the electrode device;
a cover device enclosing the inner housing region and overlying the movable diaphragm device.
