A method of manufacturing an earphone head

Abstract

The invention discloses an earphone head manufacturing technology, comprising the steps of S1, carrying out injection moulding; S2, carrying out intermediate processing; S3, spraying paint and spraying inner surfaces of an upper earphone shell and a lower earphone shell by employing silver paint; and S4, carrying out ultrasonic welding, wherein an injection moulding material is a PC transparent wear-resistant material. The S3 comprises the steps of S301, spraying the paint for the first time; and S302, spraying the paint for the second time. According to the technology, the special manufacturing demand of the earphone head can be satisfied, and the manufactured earphone head has high optical performance, wear resistance and oxidation resistance. When the manufacturing technology is used for manufacturing, the properties of various materials can be utilized well, various performances of the earphone head can reach the manufacturing demand, and the sound quality effect and appearance effect of the earphone head are improved.

And people have different requirements for external features such as the shape and texture of the earphones, as well as the sound quality and sound style of the earphones. Most of the existing earphone shells are made of plastic, and some are made of metal or wood shells. Most of the shapes are painted externally. The paint layer is easy to be worn, and it is also easy to be eroded and discolored by human sweat, which will damage the appearance of the earphone shell.
