Abstract
A lens assembly driving module includes a holder, a metal yoke, a lens unit, a magnet set, a coil, at least one elastic element and at least one damper agent. The metal yoke is coupled with the holder and includes a through hole and at least one extending structure. The extending structure is disposed around the through hole and extends along a direction from the through hole to the holder. The lens unit is movably disposed in the metal yoke. The lens unit includes an optical axis and at least one notch structure. The notch structure is disposed in an outer peripheral area of the lens unit and is corresponding to the extending structure. The damper agent is disposed between the extending structure of the metal yoke and the notch structure of the lens unit. The damper agent is applied to damp a movement of the lens unit.
