Problems solved by technology

[0002] The iron core is an indispensable core component of the loudspeaker. During the working process, the iron core will produce loss. At the same time, under the condition of long-term use, the surface of the iron core will age, which greatly reduces the service life of the iron core.
At the same time, the loudspeaker iron core produced by the existing technology has a high scrap rate, which causes great waste; and the production cost of the existing technology is relatively high, which seriously increases the production cost of the loudspeaker iron core, which is not conducive to the production of the loudspeaker iron core.
