The decorative board 30 includes a board body 31 and a decorative protrusion 32 provided on a side of the board body 31 facing away from the circuit board 21, wherein the decorative board 30 may be formed into a decorative PCBA having no actual circuit structure by injection molding or other means, the board body 31 serves as the decorative circuit board 21 having no actual circuit, and the decorative protrusion 32 serves as a decorative electronic device, in other words, an appearance similar to that of the PCBA may be provided by the decorative board 30. Thus, the user can see the structure inside the electronic device through the partially or completely transparent shell 10, see the decorative board 30 inside the electronic device, visually obtain the effect of seeing the internal PCBA, have a feeling of science and technology, and the user experience is improved. While improving the visual experience, the original circuit module 20 can be used without adding higher cost to improve the optimized circuit board 21 layout. In addition, the plate-like plate body 31 and the raised decorative convex portion 32 can provide a three-dimensional visual effect.

It will be appreciated that when the decorative board 30 is applied as a decorative dummy PCBA, the visual experience can be enhanced by painting, coating, etc. on the board body 31 and the decorative protrusion 32 of the decorative board 30. It should be noted that the decorative board 30 may be applied as a decorative PCBA, and the decorative protruding portion 32 may enhance the internal structural beauty in other ways.
