Abstract

The invention discloses a method for manufacturing a customized earphone in higher efficiency. The method for manufacturing the customized earphone comprises the steps of 1) manufacturing an ear printed mold; 2) waxing the surface of the ear printed mold; 3) pouring silica gel or agar in a mold cavity which regards the ear printed mold as a mold core and taking out the ear printed mold after the silica gel or the agar is cured to obtain a female mold; 4) injecting photosensitive resin into the female mold, then performing photo-curing processing, and then taking out a cured earphone shell from the female mold; 5) mounting a sounding unit in the earphone shell, then sealing the earphone shell opening by using the photosensitive resin and by combining with the photo-curing processing; 6) sanding the whole surface of the earphone shell, then removing particles, grease and moisture on the surface of the earphone shell; and 7) coating the whole surface of the earphone shell with the photosensitive resin, then performing the photo-curing processing and finally obtaining an earphone finished product. According to the method for manufacturing the customized earphone, the polishing procedure which wastes time and energy is left out, the processing time is shortened greatly, and the surface of the finally obtained earphone finished product is very smooth and exquisite.

Description

technical field [0001] The invention relates to a manufacturing method of earphones, in particular to a manufacturing method of customized earphones. Background technique [0002] Custom earphones are earphones in which the earphone shell is customized according to the shape of the wearer's ear canal. The conventional production process of customized earphones includes: 1) making ear impressions; 2) waxing the surface of the ear impressions; 3) pouring silica gel or agar into the cavity with the ear impressions as the core, and waiting for it to solidify Then take out the ear impression to obtain the female mold; 4) inject photosensitive resin into the female mold, then carry out light curing treatment, and then take out the cured earphone shell from the female mold; 5) install the sound unit in the earphone shell , and then use photosensitive resin combined with photocuring treatment to seal the mouth of the earphone shell; 6) The earphone shell is polished and polished as...
