Abstract
An exemplary lens driving apparatus includes a first retaining frame having first retaining portions, first coils of wire received in the first retaining portions, and a voice coil motor movably received in the first retaining frame. The voice coil motor includes a second retaining frame having second retaining portions, magnets received in the second retaining portions, and a core member having a second coil of wire wound around and being movably received in the second frame. The core member receives lens therein. The magnets generate magnetic fields which are capable of driving the core member to move along the lens optical axis when the second coil of wire is electrically powered; the magnets are applied reverse force of Ampere's force when the first coils of wire are electrically powered, such that the voice coil motor together with the lens is moved in a plane perpendicular to the lens optical axis.
