Abstract
A lens moving apparatus, including a bobbin; a first coil mounted at an outer circumference of the bobbin; a first magnet moving the bobbin in a first direction parallel to an optical axis by interaction with the first coil; a housing supporting the first magnet; an upper elastic member disposed at a top surface of the bobbin and at a top surface of the housing; a lower elastic member disposed at a bottom surface of the bobbin and at a bottom surface of the housing; and first and second winding protrusions disposed with being opposite to each other, the first coil being wound on the first and second winding protrusions.
Claims19
An apparatus for focus control and optical image stabilization, the apparatus comprising:
- a housing disposed to be movable in a first direction perpendicular to an optical axis direction;
- a bobbin disposed to be movable relative to the housing in a second direction parallel to the optical axis direction and to be movable together with the housing in the first direction;
- an elastic member connected to the housing and the bobbin and supporting a movement of the bobbin in the second direction;
- a second magnet disposed in the bobbin;
- and
- a first sensor disposed opposite to the second magnet and sensing the movement of the bobbin in the second direction,
- wherein the first sensor is disposed to move together with the housing in the first direction.
An apparatus for focus control and optical image stabilization, comprising:
- a housing disposed to be movable in first and second directions perpendicular to an optical axis direction, the first direction being perpendicular to the second direction;
- a bobbin disposed to be movable relative to the housing in a third direction parallel to the optical axis direction and to be movable together with the housing in the first and second directions;
- a first coil disposed at the bobbin,
- first magnets disposed opposite to the first coil,
- an elastic member connected to the housing and the bobbin and supporting a movement of the bobbin in the second direction;
- a second magnet disposed in the bobbin;
- and
- a first sensor disposed at the housing opposite to the second magnet,
- wherein the first coil and the first magnets overlap in the first direction, and
- wherein the first sensor and the second magnet overlap in the second direction.
