Abstract: An imaging lens driving module includes a lens carrier, a molded receiving base, a rolling element, a molded frame element and a driving mechanism. The lens carrier defines an optical axis. The molded receiving base is configured to receive the lens carrier. The rolling element is disposed between the lens carrier and the molded receiving base, and the lens carrier is allowed to be displaceable along the optical axis and relatively to the molded receiving base. The molded frame element is coupled with the molded receiving base for defining an inner space to receive the lens carrier. The driving mechanism drives the lens carrier displaceable along the optical axis, and includes a driving magnet and a driving coil, wherein the driving magnet is disposed on the lens carrier, the driving coil is corresponding to and faces towards the driving magnet.

Abstract: A lens assembly module includes a base, a cover, a lens unit, an elastic element, at least two conductive elements, at least one AF coil element and at least two first magnetic elements. The cover is coupled to the base. The lens unit is movably disposed in the cover. The elastic element is coupled to the lens unit. The conductive elements are coupled to the lens unit. The AF coil element is disposed on the lens unit, and two ends of the AF coil element are electrically connected to the conductive elements, respectively. The first magnetic elements are disposed in the cover. A part of each of the inner portions is overlapped along a direction parallel to an optical axis and electrically connected to each conductive element. The AF coil element and the conductive elements are electrically connected by a welding method.

Abstract: Provided is a lens assembly driving module including a photographing lens assembly, a first driving mechanism and a second driving mechanism. The photographing lens assembly includes N lens elements and has an optical axis passing through the N lens elements. The first driving mechanism drives at least N/2 said lens elements to move along the optical axis of the photographing lens assembly. The second driving mechanism enables a relative distance along the optical axis of two adjacent ones of the N lens elements to vary. Therefore, any specific one of the lens elements is capable of being driven to optimize optical imaging resolution of various fields of view independently within a real shot at different object distances.
