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.

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.
