Lens driving module having first sensor and second magnet in alignment

A lens driving module, comprising:

• a holder, comprising an opening hole;
• a cover coupled to the holder;
• a lens movably disposed in the cover, wherein a moving direction of the lens comprises a first direction which is parallel to an optical axis of the lens;
• at least one first magnet movably disposed in the cover, wherein a moving direction of the first magnet comprises a second direction which is orthogonal to the optical axis of the lens;
• a first coil wound around an outer side of the lens, and adjacent to the first magnet;
• at least one second magnet disposed at one end of the lens which is toward the holder;
• at least one first sensor which is a Hall sensor, and for determining a relative displacement that has occurred in the first direction between the first sensor and the second magnet via a magnetic field, wherein the magnetic field is varied according to the relative displacement, and the first sensor and the second magnet are in alignment along the first direction;
• at least one second sensor for detecting a magnetic field of the first magnet, wherein the magnetic field of the first magnet is varied according to a relative displacement between the second sensor and the first magnet which is detected;
• an imaging element for receiving an imaging light of the lens;
• and
• a circuit board, wherein the circuit board and the lens are arranged along the first direction, and the imaging element is disposed on the circuit board.
