Description

Small horn vibrating piece and manufacturing method thereof

technical field

Please refer to FIG. 1 , the existing small horn vibrating piece 10 includes a plurality of fibers 11 . 10% of the existing small horn vibrating piece is fully woven with cotton fibers 11 . Because the cotton fiber 11 is quite thick, the yarn count of the woven small horn vibrating piece 10 is less than 60. A too low yarn count means that the yarn density of the existing small horn vibrating piece 10 is low, so the following problems will occur: first, the structural strength of the small horn vibrating piece 10 is poor; second, the fiber 11 The gap between them is large. Any of the above-mentioned problems will seriously affect the performance of the small horn vibrating plate, and affect the sound quality of the horn, not to mention two problems occur simultaneously on the existing small horn vibrating plate 10, so that the small horn vibrating plate 10 is installed The sound quality of the speaker is not good.

There is a kind of existing small-sized speaker vibrating piece that utilizes polym-phenylene isophthalamide fibers to interweave 100% completely. Because the polym-phenylene isophthalamide fiber is quite thin, the yarn count of the small-sized horn vibrating piece woven into is higher than 60, which solves the existing small-sized horn vibrating piece mentioned in the preceding paragraph.

However, there is a very serious problem in the existing small horn vibrating piece that completely utilizes polym-phenylene isophthalamide fiber: in the process of weaving the existing small horn vibrating piece, each polyisophthalamide fiber Diformyl m-phenylene diamide fibers are prone to static electricity with adjacent polym-phenylene isophthalamide fibers. This problem makes the polym-phenylene isophthalamide fiber easy to break during the weaving process, causing the small horn vibrating piece to become a defective product, which greatly reduces the yield of the existing small horn vibrating piece .
