In other alternative embodiments, the housing 10 may be a cover plate of the display screen assembly 300 in an electronic device. In the following description, the case 10 is described as an example of a rear case of a cellular phone.

As shown in fig. 3 and 4, in the present embodiment, the housing 10 includes a flat plate 100 and a bent edge 200. The beads 200 are disposed at the edges of the flat plate 100, perpendicular to the flat plate 100, and smoothly transition with the flat plate 100.
