The speaker net of Bluetooth audio is often called the iron net, which shows that the iron net is the mainstream.
Common materials are iron mesh, aluminum mesh, steel mesh, stainless steel, etc. The processing of surface holes mainly includes punching, drilling, etching, weaving and other methods. In addition to the common round holes, there are also square holes, hexagonal holes, special-shaped holes, etc.
The thickness of the iron mesh commonly used on Bluetooth speakers is 0.5mm, and the thinner it is, the worse the strength is and the easier it is to deform.
The speaker net can be regarded as a hardware with holes, and the corresponding structure can refer to the design of the hardware.
The forming of the speaker net is mainly a set of sheet metal technology, so it is basically supplied by some hardware manufacturers. It can be made into various stamping shapes, simple and complex.
Because the speaker net is a thin-walled part, it has greater plasticity and elasticity, and can be disassembled and assembled. In addition, it should be noted that the accuracy and stability of some molding dimensions of the speaker net are not as good as plastic parts, and the more complex the more so.
Loudspeaker nets are usually folded around the edges, firstly for the convenience of fixing, and secondly to hide the burr-like edges, otherwise other parts are required to cover the edges.
After the loudspeaker net is made, it is generally necessary to use a plastic shell to make adjustments and perfect details.
It is more convenient to adjust and optimize the design of the loudspeaker net before the mass production of the mold, and try not to change it after the final large mold is completed.
The surface of the iron mesh is usually painted, which plays the role of color matching and antirust, and the surface can be made in any color.
