Abstract

There is provided a lens actuator, including: a lens barrel in which at least one lens is provided on an optical axis; a magnetic part provided on one surface of the lens barrel; and a printed circuit board in which a coil pattern part generating electromagnetic force is provided, the printed circuit board having one surface facing the magnetic part, wherein magnetic material is provided on the other surface of the printed circuit board.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A lens actuator, comprising:
 a lens barrel in which at least one lens is provided on an optical axis;   a magnetic part provided on one surface of the lens barrel; and   a printed circuit board in which a coil pattern part generating electromagnetic force is provided, the printed circuit board having one surface facing the magnetic part,   wherein magnetic material is provided on the other surface of the printed circuit board.   
     
     
         2 . The lens actuator of  claim 1 , wherein the coil pattern part is a metal layer patterned on the printed circuit board. 
     
     
         3 . The lens actuator of  claim 1 , wherein the coil pattern part is a winding coil embedded in the printed circuit board. 
     
     
         4 . The lens actuator of  claim 1 , wherein the printed circuit board has an integrated circuit component mounted therein. 
     
     
         5 . The lens actuator of  claim 1 , wherein the printed circuit board has a position sensor mounted therein to sense the position of the lens barrel. 
     
     
         6 . The lens actuator of  claim 5 , wherein the coil pattern part surrounds the position sensor. 
     
     
         7 . The lens actuator of  claim 1 , wherein the magnetic material is magnetic paste.
