[0002] There are several different types of horns. One is a wind instrument that is thin at the top and thick at the bottom, and is mostly made of copper. Another is a modern electro-acoustic component that converts electrical signals into sound, also called a loudspeaker. It can also be used to describe someone who advocates for others.

[0003] However, in the prior art, the existing speaker dust screen production requires equipment to punch it. If it is cut manually, it will lead to slow production. In addition, the speaker dust screen is a soft product. When the speaker dust screen strips are punched, it is easy for it to remain in the punch. Long-term accumulation during the punching process can easily affect the punching of the next one. Therefore, the equipment needs to be set so that the speaker dust screen can automatically fall off after punching. At the same time, the punching components can also be disassembled and replaced according to the processing size of the speaker dust screen.

[0004] Therefore, we need a punching device for the production of speaker dustproof nets, which can solve the punching problem in the existing speaker dustproof net production process and can also realize the automatic falling of the residual dustproof net in the punch during the punching process of the speaker dustproof net production.
