Abstract:
A camera driving module includes: a base including a central opening; a casing disposed on the base and including an opening hole corresponding to the central opening; a lens unit movably disposed on the casing; and a focus driving part. The focus driving part includes a carrier, an AF coil element, at least two permanent magnets and a Hall element. The carrier is disposed on the lens unit and movable in a direction parallel to an optical axis. The AF coil element is fixed to the base and faces toward the carrier. The permanent magnets are fixed on one side of the carrier facing toward the base and disposed opposite to each other about the optical axis. The Hall element faces toward a corresponding surface of one of the permanent magnets. The AF coil element and the corresponding surfaces are arranged in the direction parallel to the optical axis.
