An electromagnetic driving mechanism is provided for driving two different optical lenses, including a base, a first holder, a frame, a resilient element, a first electromagnetic driving assembly, a second holder, and a second electromagnetic driving assembly. The first and second holders are provided for holding the optical lenses. The frame is affixed to the base, has magnetically permeable material, and surrounds the first holder. The resilient element connects the first holder with the frame. The first electromagnetic driving assembly is disposed between the first holder and the frame to drive the first holder moving relative to the base. The second electromagnetic driving assembly is disposed on an outer side of the second holder to drive the second holder moving relative to the base.
