Abstract: An embodiment comprises: a housing comprising a first protrusion and a second protrusion on the lower part; a bobbin disposed inside the housing; a first coil disposed on the bobbin; a magnet disposed in the housing and opposite from the first coil; a second coil disposed on the outer lateral surface of the housing; an upper elastic member coupled to the upper part of the bobbin; and a lower elastic member coupled to the lower part of the bobbin. The lower elastic member comprises a first spring, a second spring, a third spring and a fourth spring which are disposed away from each other. One part of the second coil is wound at least once around the first protrusion and is connected to the first spring. The other part of the second coil is wound at least once around the second protrusion and is connected to the second spring.

Abstract: A lens moving apparatus includes a housing, a bobbin disposed in the housing, a first coil disposed on the bobbin, a magnet configured to move the bobbin in a first direction parallel to an optical axis by an electromagnetic interaction with the first coil, an elastic member coupled to the bobbin, and a second coil disposed on the housing. A first portion of the second coil is coupled to the housing. The second coil generates an induction voltage resulting from an inductive interaction with the first coil when the bobbin moves in the first direction.
