1. An optical member driving mechanism, comprising:
a movable portion, configured to connect an optical member;
a fixed portion, wherein the movable portion is movable relative to the fixed portion;
a first driving assembly, configured to drive the movable portion to move relative to the fixed portion in a first dimension, wherein the first driving assembly comprises:
a first coil, connected to the fixed portion; and
a first magnetic member, disposed on the movable portion and corresponding to the first coil, wherein as seen from a winding axis of the first coil, the first coil has a longitudinal structure; and
a second driving assembly, configured to drive the movable portion to move relative to the fixed portion in a second dimension, wherein the second driving assembly comprises:
a second coil, connected to the fixed portion; and
a second magnetic member, disposed on the movable portion and corresponding to the second coil, wherein as seen from a winding axis of the second coil, the second coil has a longitudinal structure;
wherein as seen from the winding axis of the second coil, a longitudinal axis of the first coil is parallel to a longitudinal axis of the second coil;
wherein the movement of movable portion relative to the fixed portion in the first dimension is a rotation of the movable portion relative to the fixed portion around a first axis, the movement of the movable portion relative to the fixed portion in the second dimension is a rotation of the movable portion relative to the fixed portion around a second axis, and the first axis is substantially perpendicular to the second axis.
