A two-stage lens driving device includes a lens holder, a guiding
mechanism, and an electromagnetic actuating mechanism. The guiding
mechanism is joined with the lens holder for guiding the lens holder
moving along an axial direction. The electromagnetic actuating mechanism
includes a magnetic induction member, a first coil member, and a second
coil member. The magnetic induction member is mounted on and movable with
the lens holder. The first and second coil members are respectively
located at two tail ends of the magnetic induction member. The first coil
member, the magnetic induction member, and the second coil member are
arranged linearly parallel to the axial direction. A distance between the
coil members is greater than a length of the magnetic induction member
along the linear direction. By applying current to one of the coil
members, the magnetic induction member is driven to move between the
first and the second coil members.
