Abstract: An electromagnetic driving device is provided, which includes a stationary member, an OIS driving circuit, a movable member, and a protection member. The OIS driving coil is disposed on the stationary member. The movable member is disposed in the stationary member and includes a frame and a magnetic element. The frame surrounds a main axis.The magnetic element is disposed on the frame and faces the OIS driving coil in a direction that is parallel to the main axis. The protection element is disposed on a side of the magnetic element that is away from the main axis and is in contact with the magnetic element. In addition, in a direction that is perpendicular to the main axis, the protection element faces the stationary member and is spaced apart from the stationary member by a distance.

Abstract: An electromagnetic driving device is provided, which includes a movable member, a stationary member, a driving magnet, a driving coil, a conductive layer, and an external terminal. The movable member and the stationary member are arranged separate from each other along a main axis. The driving magnet is positioned on the movable member. The driving coils are arranged corresponding to the driving magnet and are disposed in the stationary member. The conductive layer is electrically connected to the driving coils and is disposed in the stationary member. The external terminal is exposed by the fixed member and electrically connected to the conductive layer. The thickness of the external terminal is different from the thickness of the conductive layer.
