Problems solved by technology

[0003] And the making of existing plastics or sound box net cover product is not one-shot molding, and plastic net cover carries out punching and drilling on preformed plastic plate; Not environmentally friendly
Moreover, the mesh speaker cover has tens of thousands or even tens of thousands of holes. With this secondary processing technology, the production efficiency is low and the cost is high.

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0021] The technical scheme of concrete implementation of the present invention is:

[0022] Such as figure 1 , figure 2 As shown, the present invention provides a BMC mesh speaker mask containing wood fiber, which is injection molded by BMC plastic and wood fiber, and the mesh of the mesh speaker mask is a through hole.

[0023] The present invention also provides the injection molding process of the above-mentioned BMC mesh speaker mask containing wood fiber, comprising the steps of:

[0024] 1) Clean the mold 1, evenly apply a release agent on the inner surfaces of the upper and lower molds 11 and 12, and then close the mold; the release agent is ben...

Abstract

The invention provides a BMC mesh speaker mask containing wood fiber, which is formed by one-time injection molding of BMC plastic and wood fiber, and the mesh holes of the mesh speaker mask are through holes. The present invention also provides an injection molding process for the above-mentioned BMC mesh speaker mask containing wood fiber. The BMC mesh speaker mask containing wood fiber of the present invention has a plastic mesh containing wood fiber, which can preserve the original sound quality of the speaker to a large extent, and its plastic material can also play a good role in protecting the speaker.

Description

technical field [0001] The invention relates to a BMC mesh sound box mask containing wood fiber and an injection molding process. Background technique [0002] At present, most of the speaker net covers widely used in the market are still dustproof, beautiful and protective. However, due to the different materials, thicknesses and density of the mesh cover, it will have a certain impact on the sound emitted by the speaker in the speaker, especially the mesh cover has a certain attenuation effect on the high-pitched part. On the material of the net cover, there are nothing more than various fiber materials, or metal and plastic. Softer fiber materials have less impact on the sound, but relatively, in some cases, the protection of the speaker unit is also weaker, and once it is pierced or damaged, the sound will be greatly affected. Harder metals, plastics, etc. are basically used for dust prevention and protection, and often do not involve direct consideration of sound qual...
