Abstract
A lens driving module includes a reflecting element, a base, a frame, a holder, an optical lens, a first electromagnetic driving assembly, and a second electromagnetic driving assembly. The frame is connected to the base, and the holder holds the optical lens and movably connects to the base. The reflecting element reflects light from the outside along a light incident direction to an optical lens along a first direction, wherein the light incident direction is perpendicular to the first direction. The first and second electromagnetic driving assemblies force the holder to move relative to the base, wherein the first electromagnetic driving assembly has a first drive coil, the second electromagnetic driving assembly has a second drive coil, the first and second drive coils have elongated structures extending in a second direction and the first direction respectively, and the first direction is perpendicular to the second direction.
