Abstract: A lens device comprises a connect assembly, a lens assembly and a drive assembly. The lens assembly is disposed on the connect assembly and has a central axis. The drive assembly comprises a first coil, a magnet and a second coil. The first coil is wound around the lens assembly. The magnet is disposed on the connect assembly and has a first magnetic pole, a second magnetic pole, a first direction of magnetic field and a second direction of magnetic field. The first direction of magnetic field and the second direction of magnetic field are not parallel to each other. The first direction of magnetic field points toward the first coil. The second coil is disposed on the connect assembly. The second direction of magnetic field points toward a part of the second coil.
