Case for electronic device and magnetic assembly

A case for an electronic device, comprising:

• a case wall, defining a receiving cavity for receiving the electronic device;
• and
• a magnetic assembly, comprising:
• a ring-shaped support member, connected with the case wall and capable of moving relative to the case wall so as to support the case;
• and
• a plurality of magnetic alignment elements, arranged inside the ring-shaped support member;
• wherein, the ring-shaped support member comprises an operation portion, configured to be operated by a user to move the ring-shaped support member;
• the operation portion has a recess;
• the ring-shaped support member has an outer surface facing away from the case wall, an inner surface facing towards the case wall, and a circumference surface that connects the inner surface with the outer surface;
• the recess extends through the ring-shaped support member from the outer surface to the inner surface, the circumference surface comprises an outer circumference surface and an inner circumference surface;
• the outer circumference surface faces away from a geometrical center of the ring-shaped support member;
• the inner circumference surface faces towards the geometrical center of the ring-shaped support member;
• the recess of the operation portion is recessed from the outer circumference surface towards the geometrical center of the ring-shaped support member;
• the magnetic assembly further comprises a connecting member, rotatably connected to the ring-shaped support member and fixedly connected to the case wall;
• the case wall has an outer surface and an inner surface, wherein the outer surface of the case wall faces away from the receiving cavity, and the inner surface of the case wall faces towards the receiving cavity;
• and
• the connecting member comprises a first connecting element and a second connecting element;
• the first connecting element is fixedly connected to the outer surface of the case wall;
• the second connecting element is fixedly connected to the inner surface of the case wall;
• the first connecting element is fixedly connected to the second connecting element to clamp a portion of the case wall between the first connecting element and the second connecting element.
