Classification: CPC H | IPC H

Claim 24:
25. A method of fabricating a micro speaker device, the method comprising:
coupling a first silicon substrate comprising a movable diaphragm device, and configured using a first silicon material to generate a variable pressure to output an acoustic signal, the movable diaphragm device having a free standing peripheral region, the movable diaphragm device being coupled to an actuator device such that the movable diaphragm device is coupled to the movable diaphragm device using a shaft device, to an electrode device operably coupled to the actuator device and configured to electrostatically move the actuator device, the electrode device being provided on a second silicon substrate comprising a plurality of CMOS cell regions;
a cover member provided from a third silicon substrate overlying the movable diaphragm device.
