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.
Claims21
A lens moving apparatus comprising:
- a bobbin configured to be coupled with a lens;
- a coil disposed on an outer surface of the bobbin;
- a first magnet facing the coil;
- a housing for supporting the first magnet;
- 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 the inner frame and the outer frame of the upper elastic member are connected to each other through an upper connection portion,
- wherein the inner frame and the outer frame of the lower elastic member are connected to each other through a lower connection portion, and
- wherein at least one of the upper connection portion and the lower connection portion has a first region and a second region, and a cross section of the first region, taken through the first region in a first direction that is perpendicular to an optical axis of the lens, is different from a cross section of the second region, taken through the second region in the first direction.
