Description

Technical Field

[0002] Speaker shells are generally made of stainless steel, aluminum alloy and plastic. Stainless steel shells have the advantages of dirt resistance, strong metal texture, good sealing, better sound quality, strong plasticity, oxidation resistance, low processing difficulty, short construction period, and cost saving; while aluminum alloy takes a long time to open the mold and the processing speed is slow, which increases the production cost; plastic is not dirt-resistant, has a low texture, low strength, is affected by the temperature and causes thermal expansion and contraction, and has poor sealing. Therefore, in comparison, stainless steel speaker shells are better.

[0003] When processing the speaker shell plate, it is necessary to cut the shell plate according to the different speaker sizes. Most of the existing speaker shell plate processing methods are manual cutting, where the plate is clamped and fixed by a clamping assembly, and then the plate is cut by a manual handheld cutting machine. After cutting, the plate needs to be turned over and cut again. The speaker shell plate processing efficiency is very slow, which can easily delay the production progress of the speaker.
