It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings that is solely for the purpose of facilitating the description and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to 5, the present application provides a light-weight housing of a keyboard, where the housing 10 is composed of a bottom plate 11 and an assembly substrate 12, and optionally, the bottom plate 11 and the assembly substrate 12 may be connected by glue, screws, or the like. The bottom plate 11 and the assembly substrate 12 both include a glass fiber layer 20, the glass fiber layer 20 is a plurality of layers, and the plurality of glass fiber layers 20 are laminated to form the bottom plate 11 or the assembly substrate 12.

Alternatively, the thicknesses of the bottom plate 11 and the assembly substrate 12 can be controlled according to the actual requirement, in this embodiment, the thickness of the assembly substrate 12 is 7mm, the thickness of the bottom plate 11 is 2mm, and the relatively thin assembly substrate 12 and the bottom plate 11 form a relatively thin housing.

Each of the glass fiber layers 20 includes a glass fiber cloth 21 and a resin layer 22. The glass fiber cloth 21 has three layers, the three layers of glass fiber cloth 21 are sequentially stacked and are stitched together through vertically extending polyester yarns (not shown), so that the three layers of glass fiber cloth 21 form a whole, and the structural strength can be greatly improved. The resin layer 22 covers the three layers of the glass fiber cloth. By using the glass fiber layer 20 composed of the resin layer 22 and the glass fiber cloth 21 having a light weight as a base material, the manufactured housing has characteristics of light weight and high structural strength.

Each glass fiber cloth 21 comprises warp yarns 201, weft yarns 202 and polyester yarns 203; the polyester yarns 203 weave the warp yarns 201 and the weft yarns 202 together, and optionally, the polyester yarns 203 weave the warp yarns 201 and the weft yarns 202 into a whole in a chain weaving mode.
