The back cover 12 is in abutment with one side of the middle frame.

[0039] In some embodiments, the circuit board 30 can be the mainboard in the electronic device 100. As an example, the circuit board 30 can be the mainboard of a mobile phone.

[0040] The camera decoration piece 14 can be used to improve the appearance of the electronic device 100 and facilitate the layout of some internal electronic components. Specifically, the camera decoration piece 14 can be used to decorate multimedia devices such as cameras, flashlights, and laser devices to improve the appearance of the electronic device 100 and facilitate the layout of these multimedia devices. The camera decoration piece 14 can cover, protect, and block light for the camera module of the electronic device 100 to ensure the performance of the electronic device 100 in effectively taking pictures using the camera module.

[0041] The camera decoration piece 14 is arranged on the back cover 12.

[0042] As shown in FIG. 2, the camera decoration piece 14 includes a first decoration piece 142, a second decoration piece 141, and a cover 17. The second decoration piece 141 and the first decoration piece 142 are arranged on two opposite surfaces of the back cover 12, respectively. The second decoration piece 141 and the first decoration piece 142 are both substantially ring-shaped.

[0043] The back cover 12 is a protective structure at the back of the electronic device 100. The back cover 12 can protect the internal components of the electronic device 100.

[0044] It can be understood that FIG. 1 and FIG. 2 schematically show some structural components included in the electronic device 100, and the actual structure and position of these structural components are not limited by FIG. 1 and FIG. 2. The electronic device 100 can actually have more or fewer structural components than those shown in FIG. 1 and FIG. 2, for example, the electronic device 100 also includes physical buttons (not shown in the figures) and a display screen (not shown in the figures).

[0045] As shown in FIG. 3 and FIG. 4, the back cover 12 has a top short side 121, a bottom short side 122 opposite to the top short side 121, and two long sides 123 connecting between the top short side 121 and the bottom short side 122.
