<p>A lens module comprises a base (10), two guide pins, two conductive plates (30) mounted on the base (10), a bottom plate positioned on both conductive plates (30), a lens holder comprising an annular frame, two springs (60) mounted on guide pins, a camera lens (80), a coil mounted on the annular frame of the lens holder, two magnets clamped symmetrically to one another on the left and right side of the coil, a top plate (110) adapted for the base (10) and joined together as a single-piece lens module for firmly holding both magnets between the top cover (110) and the bottom plate. The alternating action between the coil and the magnets gives rise to an electromagnetic force giving the axial movement of the lens holder unit.</p> |
