The taper angles θ 1, θ 2, θ 3 of the first pyramid 101 (e.g., θ 1 is 80 °, θ 2 is 60 °, θ 3 is 40 °, and other angles are possible in other embodiments and are not limited herein). Preferably, the first triangular pyramid and the second triangular pyramid are arranged identically and are distributed 180 degrees apart in the array unit. Preferably, the base surfaces of the first and second triangular pyramids are combined (integrated) and distributed in the parallelogram. The pyramid array of the present embodiment can be formed by imprinting through a mold having a predetermined shape during manufacturing, and the conical surfaces (cone areas) of the same type of cones of different array units on the same side (e.g., a, b, c) are the same at the same angle. Or machined by a cutter, and when machining, the machined surface is machined sequentially from 3 angles (a, b, c) to obtain the pyramid texture. The processing surface of the cover plate (in this case, the film is disposed in advance on the cover plate) may be machined by a cutter, and during machining, the processing surface may be sequentially machined from 3 angles (a, b, and c) to form a pyramid texture (which is also called an anisotropic texture with respect to a regular pyramid). In other embodiments, the pyramid may be a rectangular pyramid, a pentagonal pyramid, or a polygonal pyramid, which is configured such that the areas of the tapered surfaces of the pyramid are different, or the areas of at least 2 tapered surfaces are different. Therefore, when the light is irradiated, the light shadow generated by different reflection angles and reflection amounts of the conical surfaces with different areas has light and shade difference.

In one embodiment, the apex of the pyramid can be pointed (i.e., the apex has a point), or pointed, where the apex comprises at least a small segment of a line.

In one embodiment, at least two of the tapered surfaces of the pyramid are not identical.

The present application also provides a cover plate that carries the diaphragm described above. The cover plate is preferably used for portable intelligent devices such as mobile phones, PADs and the like.

When the texture containing the pyramid is manufactured, the texture can be formed by impressing through a preset-shaped die or processed through a cutter on the bearing layer, and when the triangular pyramid is taken as an example, the processing surface is processed in sequence from 3 angles to obtain the pyramid texture. Alternatively, the machined surface of the cover plate is machined by a cutter, and in the case of a triangular pyramid, the machined surface is machined sequentially from 3 angles to form a pyramid texture (which is also called an anisotropic texture with respect to a regular pyramid). Preferably, the different faces of the pyramid are formed by cutting with different cutters, and the conical faces on different cones formed by cutting with the same cutter are the same, i.e. the conical faces on different cones on the same side face are the same.
