ABSTRACT:
A camera module includes a lens barrel, an image sensor, a holder and a driving member. The lens barrel and the image sensor are received in the holder. At least one magnet is arranged on the outer wall of the holder. The driving member includes a spherical casing, a plurality of induction coils and a control unit. The casing has an opening for entry of the holder. The plurality of induction coils is mounted on the inner wall of the spherical casing. The control unit is received in the spherical casing. The control unit is electrically connected with the induction coils. The control unit is configured for controlling the electric current through the induction coils to form an electromagnetic field, thus a magnetism is generated between the at least magnet and the electromagnetism.
