摘要:
A lens driving apparatus with a closed-loop anti-shake structure, including: a lens holder including a coil; a frame including a plurality of magnets and receiving the lens holder; a driving circuit board disposed under the frame; a plurality of first set of elastic bodies configured such that the lens holder remains movable in a direction of a first axis with respect to the frame; a plurality of second set of elastic bodies configured such that the frame remains movable in a direction perpendicular to the first axis with respect to the driving circuit board; and a first optical module and a first optical reference respectively disposed at the driving circuit board and the lens holder, the first optical module sensing a relative movement of the first optical reference so as to sense a movement of the lens holder in the direction of the first axis.
