Abstract
Embodiments provide a lens moving apparatus including a housing for supporting a first magnet, a bobbin including a coil disposed on an outer surface thereof and inside the first magnet so as to move in the housing in a first direction parallel to an optical axis by electromagnetic interaction between the first magnet and the coil, and upper and lower elastic members, each of which is provided at the bobbin and the housing and includes an inner frame coupled to the bobbin and an outer frame coupled to the housing, wherein at least one of the upper and lower elastic members is constituted by a printed circuit board.
Claims20
A lens moving apparatus comprising:
- a housing;
- a bobbin disposed in the housing;
- a first magnet disposed on the housing;
- a coil disposed on the bobbin;
- an elastic member comprising an outer frame coupled to the housing, an inner frame coupled to the bobbin, and a connection portion connecting the outer frame and the inner frame;
- and
- a damper disposed between the housing and the connection portion;
- wherein the connection portion comprises a first end connected to the outer frame and a second end connected to the inner frame,
- wherein the damper is spaced apart from the inner frame,
- wherein the outer frame comprises a first hole and the inner frame comprises a second hole,
- wherein the first hole is closer to the first end of the connection portion than is the second hole,
- wherein the second hole is closer to the second end of the connection portion than is the first hole, and
- wherein the damper is closer to the first hole of the outer frame than it is to the second hole of the inner frame.
