Abstract: A lens assembly driving apparatus includes a holder, a metal yoke, a carrier, a lens assembly, a magnet set, a coil and at least one elastic element. The metal yoke is coupled with the holder. The carrier is movably disposed in the metal yoke. The carrier includes an object-side portion and at least three inner surfaces. The object-side portion has an object-side central hole. The lens assembly has an optical axis. The optical axis is corresponding to the object-side central hole. The lens assembly is coupled in the carrier. A movement of the lens assembly relative to the holder is according to a movement of the carrier. The magnet set includes only two magnets. The coil surrounds and is fixed at an exterior of the carrier. The elastic element is coupled with the carrier and the holder.

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.
