Problems solved by technology

Earphone hangers made of stainless steel often release nickel, and the amount of nickel released is relatively large, which can easily cause skin allergies for earphone hangers
[0005] In addition, the stainless steel earphone hangers in the prior art, because some stainless steel materials contain toxic beryllium elements, such stainless steel earphone hangers containing beryllium elements will release toxic beryllium and penetrate into the earphone hangers during long-term use. in the skin of the user, thus detrimental to human health

Abstract

The invention relates to the technical field of an earphone hanger, and in particular relates to an amorphous alloy earphone hanger as well as an earphone and a manufacturing method thereof. The earphone hanger is an amorphous alloy earphone hanger which is manufactured by a zirconium base amorphous alloy, a copper base amorphous alloy, a titanium base amorphous alloy, a nickel base amorphous alloy, a palladium base amorphous alloy or an iron base amorphous alloy. The hardness of the earphone hanger is 400-600, the intensity is 100-300 MPa, the elastic limit is 2-3%, and the release of nickel is 0-0.015 mg / cm<2> / week. The surface of the earphone hanger is corrosion-free after being subjected to a 500-2000h of salt spray test. According to the manufacturing method of the amorphous alloy earphone hanger, the amorphous alloy earphone hanger is manufactured by means of an alloy ingot of the amorphous alloy through a die-casting molding method, a melt spinning method, a suction casting method, a rapid electric discharge molding method, a continuous casting method or a thermoplastic molding method. The amorphous alloy earphone hanger has the advantages of high strength, hardness and elasticity, and is wear-resistant, scrape-resistant and corrosion-resistant, and also has hypoallergenic, antimagnetic properties and good comfortable degree.

Description

technical field [0001] The invention relates to the technical field of earphone hangers, in particular to an amorphous alloy earphone hanger, earphones and a manufacturing method thereof. Background technique [0002] Earphone hangers in the prior art are mostly made of stainless steel or plastic. Due to the frequent use and frequent movement of the earphone hanger, it is easy to step on or break the earphone hanger. The headphone hanger made of all plastic is very easy to be damaged or broken, so it is generally not made of all plastic to make the headphone hanger. In the prior art, stainless steel is mostly used to prepare earphone hangers. However, the earphone hangers made of stainless steel have defects such as poor strength, hardness, elastic limit, wear resistance, scratch resistance, and corrosion resistance. In particular, the comfort of the stainless steel earphone hanger is not enough due to the defect of elastic limit performance in the stainless steel earphone...
