Abstract:
An electromagnetic driving module is provided, including a first member, a second member movably connected to the first member, an electromagnetic driving assembly, and a film. The electromagnetic driving assembly includes a magnet and a coil respectively disposed on the first and second members, so as to move the second member relative to the first member. The film is disposed on a side of the magnet to reduce magnetic interference between the magnet and a magnetic element, wherein the magnetic permeability of the film is higher than the magnetic permeability of the first member.
