Abstract
The present disclosure provides a lens driving device which is small and has good focus adjustment and hand shake correction. The lens driving device includes: a case; a lens module; a support frame; a spring leaf; a support part connecting the support frame with the fixing base in such a manner that the support frame is freely movable relative to the fixing base in a direction orthogonal to an optical axis of a lens; a magnet steel; a first driving coil; and a second driving coil. Under an electromagnetic interaction between the second driving coil and a second portion of the magnet steel opposite to the second driving coil, the support frame moves relative to the fixing base in the direction orthogonal to the optical axis of the lens.
