Lens device
First Claim
1. A lens device, comprising:
- a connect assembly;
a lens assembly, disposed on the connect assembly, and the lens assembly having a central axis; and
a drive assembly, comprising;
a first coil wound around the lens assembly;
at least one magnet disposed on the connect assembly, the at least one magnet having 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 taken to be inward to/outward from the first magnetic pole of the magnet, the second direction of magnetic field taken to be inward to/outward from the second magnetic pole, the first direction of magnetic field and the second direction of magnetic field not parallel to each other, the first direction of magnetic field pointing toward the first coil or pointing away from the first coil, and the first coil configured for driving the lens assembly to move substantially along the central axis by interacting with the first magnetic pole; and
at least one second coil disposed on the connect assembly, the second direction of magnetic field pointing toward a part of the at least one second coil or pointing away from the part of the at least one second coil, and the at least one second coil configured for driving the lens assembly, the at least one magnet and the first coil to move along a direction other than the central axis by interacting with the second magnetic pole.

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.
