Abstract

An anti-noise sheath for headphone cables is processed from the following components by mass: 50%-60% of hydrogenated styrene-butadiene block copolymer, 10%-13% of polypropylene, 15%-20% of a filler, 5%-20% of lubricant, 1%-5% of a coloring agent, and 0.1%-0.3% of a stabilizer. The hydrogenated styrene-butadiene block copolymer, with a chemical formula of (C8H8-C4H6)x, is a hot melt-type rubber. The filler is calcium carbonate with a chemical formula of CaCO3. The lubricant is white mineral oil. The stabilizer is zinc stearate with a chemical formula of C8H16O4. The coloring agent is carbon powder. The anti-noise sheath for headphone cables of the present invention can prevent noise and has good anti-noise performance after being assembled in the cable, due to the use of the specific component composition and ratio.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a sheath for anti-noise earphone wires. Background technique [0002] Headphones are one of the indispensable components of the sound system of modern electronic equipment, and the quality of the headphones directly affects the hearing effect. Earphones usually include earplugs and wires connected to the earplugs. In the process of listening, there will always be unavoidable vibration of the wires, which will cause noise in the earplugs and affect the quality of hearing. [0003] In the prior art, in order to overcome the noise generated in the earplugs caused by the vibration of the earphone wire, a sheath is usually provided outside the earphone wire to prevent the noise caused by the vibration of the earphone wire. However, such sheaths are still not effective in preventing noise generation in the earbuds. [0004] Therefore, in view of the deficiencies of the prior art, it i...
