CAMERA ACTUATOR FOR PORTABLE TERMINAL HAVING AUTOFOCUSING AND IMAGE STABILIZATION FUNCTIONS

摘要

A camera actuator having autofocusing and image stabilization functions includes a fixing part mounted on a portable terminal; a first coil mounted on the fixed part; a first carrier installed to be movable in the direction parallel with the lens within the fixing part; a magnet mounted on the first carrier in such a manner that the outside surface of the magnet faces the first coil; a second carrier installed to be movable in the direction of an optical axis of the lens within the first carrier and moving along with the first carrier; a second coil mounted on the second carrier, disposed within the magnet and generating a second driving force to the second carrier; a lens part including at least one lens, mounted on the second carrier, and moving along with the second carrier; and a hall sensor sensing the position of the first carrier.

1. A camera actuator having auto-focusing and image stabilization functions which adjust lens focus of a camera or prevent the image-shake by moving the lens of the camera, comprising:
a fixing part mounted on a portable terminal; a first coil mounted on the fixed part; a first carrier installed to be movable in the direction parallel with the lens within the fixing part; a magnet mounted on the first carrier in such a manner that the outside surface of the magnet faces the first coil, thereby generating a first driving force to the first carrier when current is applied to the first coil; a second carrier installed to be movable in the direction of an optical axis of the lens within the first carrier and moving along with the first carrier when the first carrier moves by the first drive force; a second coil mounted on the second carrier, disposed within the magnet and generating a second driving force to the second carrier when current is applied in the second coil; a lens part comprising at least one lens, mounted on the second carrier, and moving along with the second carrier; and a hall sensor sensing the position of the first carrier.
