Patent ID: 7974022

Claim:
A lens module, comprising: a lens barrel; an annular retaining member arranged in the lens barrel; at least three driving devices arranged on the annular retaining member, each of the driving devices comprising a base attached on the retaining member, a plurality of first electrodes formed on the base and a comb-shaped carrier, the comb-shaped carrier comprising a beam attached on the base and a plurality of second electrodes extending from the beam and suspended above the first electrodes at a first position; and a first lens carried by the second electrodes of the at least three driving devices, wherein when a first voltage is applied on the first electrodes and a second voltage is applied on the second electrodes, an electrostatic force is generated between the first electrodes and the second electrodes, and the second electrodes are moved towards the first electrodes, thereby bringing the first lens to a second position.
