Abstract
Embodiments provide a lens moving apparatus including a first magnet, a housing, a bobbin, around which a coil is wound and which moves in a first direction in the housing, an upper elastic member disposed on upper surfaces of the bobbin and the housing, a lower elastic member disposed under lower surfaces of the bobbin and the housing, and a damping member disposed between the upper or lower elastic member and the bobbin.
Claims20
A lens moving apparatus comprising:
- a cover member comprising an upper surface and a plurality of lateral walls extending from the upper surface;
- a bobbin disposed in the cover member and configured to move in an optical axis direction;
- a first magnet disposed on the cover member;
- a coil disposed on the bobbin and facing the first magnet;
- an elastic member comprising an inner frame coupled to the bobbin;
- a second magnet coupled with the bobbin;
- a position sensor configured to detect the second magnet;
- and
- a damping member disposed between one portion of the elastic member and the bobbin,
- wherein the one portion of the elastic member is spaced apart from the inner frame of the elastic member,
- wherein the plurality of lateral walls of the cover member comprises first and second lateral walls opposite to each other, and third and fourth lateral walls disposed between the first and second lateral walls and opposite to each other,
- wherein the first magnet comprises a first magnet unit facing the first lateral wall of the cover member and a second magnet unit facing the second lateral wall of the cover member, and
- wherein the second magnet is disposed on a side of the bobbin that faces a direction toward the third lateral wall of the cover member.
