Abstract
The present embodiment relates to a lens driving device comprising: a housing; a bobbin disposed inside the housing; a coil disposed at the bobbin; a magnet disposed in the housing and facing the coil; an elastic member coupled to the housing and the bobbin; and a damper disposed at the elastic member, wherein the elastic member comprises an outer part coupled to the housing, an inner part coupled to the bobbin, and a connection part for connecting the outer part and the inner part; and the damper is disposed at the connection part.
Claims19
A lens driving device comprising:
- a housing;
- a bobbin disposed in the housing;
- a coil disposed on the bobbin;
- a magnet disposed on the housing and facing the coil;
- an elastic member coupled to the bobbin;
- and
- a damper disposed on the elastic member,
- wherein the elastic member comprises an inner part coupled to the bobbin, an outer part disposed outside the inner part, and a connection part connecting the outer part and the inner part, and
- wherein the damper is disposed on the connection part,
- wherein the connection part comprises a curved part having a curved shape, a first extension part extending from one end of the curved part, and a second extension part extending from the other end of the curved part,
