Abstract: An exemplary camera module includes a lens mount, a lens unit, a magnet unit, a printed circuit board (PCB)-based Rogowski coil and a blade spring. The PCB-based Rogowski coil is fixed around the lens unit. The PCB-based Rogowski coil establishes an induced magnetic field when an electric current is applied thereto. The induced magnetic field interacts with the magnet unit to generate a magnetic force moving the lens unit telescopically. The blade spring includes a plurality of ribs. Each rib includes a moveable end connected with the lens unit and an opposite fixed end. The moveable end moves together with the lens unit with respect to the fixed end to cause the ribs to distort and generate an elastic force. The lens unit stops at a focal position when the magnetic force and the elastic force come to a balance.

Abstract: A camera module includes a lens unit, a magnet, a stator and an elastic element. The stator includes an upper coil seat with an upper coil wound therearound and a lower coil seat with a lower coil wound therearound.
