Etching Boosts the Development of Speaker and Audio Network Technology

With the vigorous development of consumer electronics, the technology is from high, refined and sophisticated, and the product life cycle is constantly updated iteratively. There are many models and small batches, and the product accuracy requirements are within microns. The traditional technology cannot meet its requirements, so it also drives the continuous pursuit of the ultimate in the technology of the speaker network.

The technology of the speaker sound network is mainly stamping, laser, etching and electroforming. The traditional speaker sound network adopts the stamping technology, which has no strict requirements on the appearance. The spacing between the mesh holes is relatively large, and the stamping needs to make a mold, which is relatively high in cost. The design style cannot be changed. Although the processing cost is relatively large and the speed is fast, the cost of the mold is not low. The speaker sound network uses laser to process the holes at a slower speed, which is only suitable for the speaker sound network with a relatively small number of holes. The edge of the network will be blackened by laser. The speaker screen can be processed by etching with high accuracy. The minimum accuracy can reach 0.01MM. The standard thickness is 0.03, 0.05, 0.08, 0.1, 0.2, 0.25, and 0.3mm. The selected material standards are SUS304, 403, and 304H stainless steel. The speaker screen etching lines are uniform, without burr or notch.
