The invention relates to an lens driving device using a scientific method to prevent shaking vague images caused by shaking; the lens driving device comprises a housing, a lens barrel moving in an optical axis direction in the housing, a permanent magnet mount surrounding the lens barrel and moving along a direction vertical to the optical axis, and an OIS elastic assembly used for pulling the permanent magnet mount to a set position when the mount moves in the direction vertical to the optical axis; the OIS elastic assembly uses elastic reset force to restore the lens to the default position after lens shaking, thus realizing optical anti-shaking function, and the lens driving device is sensitive in reaction, and good in reliability. The lens driving device needs no hall sensor for inducting lens shaking, thus reducing making cost and size, and no suspension wire is needed, so assembling is easier, thus improving production efficiency. |
