Method for manufactuing vibration system parts of speaker in poly-phenylene benzobisoxazole |
| abstract |
The present invention relates to a method for manufacturing a vibration element of a speaker using polybenzoxazole, which is excellent in surface strength and durability and has high efficiency and uniform characteristics in all bands, using polybenzoxazole as a main material. The present invention relates to a method for preparing polybenzoxazole (PBO) fibers, comprising the steps of preparing a poly-phenylene benzobisoxazole (PBO) fiber and a polyethylene fiber melt-spun with a heterocyclic aromatic organic polymer, A step of injecting a crosslinking reaction material between both ionic surfactants and fibers into a sol fiber to activate the polymer fiber; spinning the activated polybenzoxazole fiber and the polyethylene fiber; spinning the fiber mixture of polybenzoxazole and polyethylene A step of weaving a fabric using a synthetic polymer resin, a step of coating the fabric with at least one synthetic polymer resin, and a step of shaping the coated fabric into the shape of a vibrator part of a speaker using a hot press machine The present invention also provides a method of manufacturing a vibrating system component of a speaker using polybenzoxazole. |
