Problems solved by technology

[0007] First of all, since the glass fiber mesh and anti-UV layer are usually attached by manual brushing or pasting, the production efficiency is low and the labor cost is high;
[0008] Secondly, and in the actual production process, if the glass fiber mesh is attached to the coating film, if there is a lack of a certain extrusion force, the degree of fit between the glass fiber mesh and the shell will not be good, and air bubbles or hollow gaps will easily occur. , affect the structural strength of the shell, even in the actual use process, after the shell is impacted, it is easy to have pits or damage near the hollow gap, which greatly affects the appearance;
[0009] Thirdly, it is difficult to control the uniformity of the wall thickness of the entire shell by spraying or pasting, resulting in uneven wall thickness of the shell, resulting in uneven internal damping force everywhere, and the degree of sound penetration is relatively chaotic, resulting in The sound effect is not good in actual use;
[0010] Finally, since there is only one layer of glass fiber mesh in this material to increase the structural strength, the effect of the coating film and the anti-UV layer on improving the structural strength is very limited, so the structural strength of the entire shell still needs to be strengthened

Abstract

The invention discloses a sound box shell, and belongs to the field of sound box equipment. The sound box shell comprises a decoration layer, a reinforced layer and a cavity setting layer, wherein the decoration layer is made of a high-molecular material; an inner wall of the decoration layer is coated with the reinforced layer; the cavity setting layer is arranged on an inner side of the reinforced layer; a filling cavity is formed between the cavity setting layer and the reinforced layer; a main body layer formed by slurry curing is arranged in the filling cavity; and the reinforced layer or / and the cavity setting layer comprises fiber meshes and a filing layer with which the fiber meshes are coated. The sound box shell has the advantages of higher structural strength, lower cost and better sound effect.

Description

technical field [0001] The invention relates to a sound box shell, which belongs to the field of sound box equipment. Background technique [0002] The existing speakers on the market, especially those for outdoor sports, have a relatively poor operating environment, so there are high requirements for the enclosure of the speakers, such as anti-UV, anti-corrosion, sealing and waterproof, high temperature resistance, etc., and the use process It is easy to be bumped and impacted, and it also puts forward higher requirements on the structural strength of the shell itself. Therefore, the material of this shell becomes particularly important. The speaker shells that appear on the market are usually made of metal or alloy materials, and some are made of Injection molding, these materials have obvious deficiencies: [0003] Taking metal or alloy material as an example, its production is basically realized by stamping, die-casting, or CNC processing, and a large amount of mold cos...
