The mesh cloth on the speaker is mainly dustproof and protective for ordinary speakers. Dust-proof is easy to understand, which is to prevent dust from falling on the speaker. The understanding of protection is that the bears and children in your house or pet cats and dogs will collapse or even break the paper cone and soft top of the horn if you are not careful. Adding this net cloth can play a certain protective role.

The dust-proof nets on the market are usually dark in color. The purpose of this design is mainly to prevent direct sunlight from melting on certain rubber components.

In addition, the speaker grille is not a simple dustproof function for Hi-fi speakers. This is actually very easy to understand. After all, the sound is made by vibration, and a layer of net is added from the speaker to the outside world, which will affect the sound to some extent.

For example, in a recording studio with strict requirements on sound, most of the monitor speakers used in recording do not have this grille. People who don't have much requirements for sound quality may feel that this really has no effect. But for audiophiles who are pursuing the ultimate in sound, this kind of grille has a particularly obvious impact on the sound when the sound pressure is loud.

The speaker grille can be made by drawing and punching a metal plate. The punching type includes round holes, rectangular holes, and square holes. The net cover is generally made of fiber materials, metal, plastic, etc.
