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.
