Abstract: An electronic device includes a rear cover and a camera decoration component. The camera decoration component includes a decoration member, a dial plate, a plurality of positioning members, and a plurality of induction members. The dial plate is annular, and is sleeved on an outer peripheral side of the decoration member. The decoration member includes a virtual rotation axis, and the dial plate is rotatably connected to the decoration member. The decoration member is configured to rotate around the virtual rotation axis of the decoration member. The positioning members and the induction members are configured to control the dial plate to be in a hovering state.

Abstract: The electronic device includes a frame, a screen, and a circuit board assembly. A part of the frame forms a radiator of an antenna, or the radiator of the antenna is fixed on an inner side of the frame. The circuit board assembly is located on the inner side of the frame. The circuit board assembly includes a first conductive member, and a first board, an elevating board, and a second board sequentially stacked. The first board is located on one side of the second board away from the screen. The first board includes a first main body portion and a first extension portion connected to the first main body portion. The first main body portion is fixedly connected to the elevating board. The first extension portion protrudes relative to the elevating board and the second board, and is disposed close to the radiator.
