Abstract:
An exemplary voice coil motor includes a movable unit, a fixed unit, and a resilient plate. The movable unit includes a hollow lens barrel for accommodating a number of lenses, and at least one fine pattern coil fixed on a sidewall of the lens barrel and configured for electrical connection to a power source. The fixed unit includes a hollow frame structured bracket and a number of magnets mounted on the bracket. The bracket accommodates the movable unit. The magnets surround and are spaced apart from the at least one fine pattern coil. The resilient plate is resiliently connected between the bracket and the lens barrel to hold the lens barrel on the bracket.
