Abstract
Embodiments provide a lens moving apparatus including a bobbin having a lens barrel, a housing configured to accommodate the bobbin, an upper elastic member coupled to the bobbin and the housing, a lower elastic member coupled to the bobbin and the housing, a first coil disposed on the bobbin, a first magnet disposed on the housing, a circuit board disposed below the housing, a second coil disposed on the circuit board, a first sensor to output a first output signal based on a sensed result of a magnetic field strength of the first magnet, a first capacitor connected in parallel to the first sensor.
Claims20
A lens moving apparatus comprising:
- a housing;
- a bobbin disposed in the housing and configured to move in a direction parallel to an optical axis;
- a position sensor comprising two output terminals and configured to sense a movement of the housing in a direction perpendicular to the optical axis;
- and
- a capacitor electrically connected in parallel to the two output terminals of the position sensor.
A camera module comprising:
- a first circuit board;
- a lens moving device disposed on the first circuit board;
- an image sensor disposed on the first circuit board;
- and
- a capacitor disposed on the first circuit board,
- wherein the lens moving device comprises:
- a housing;
- a bobbin disposed in the housing and configured to move in a direction parallel to an optical axis;
- a position sensor comprising two output terminals and configured to sense a movement of the housing in a direction perpendicular to the optical axis;
- and
- wherein the capacitor is electrically connected in parallel to the two output terminals of the position sensor.
