DETAILED DESCRIPTION

[0016] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0017] like Figures 1 to 3 As shown, the utility model provides an earphone middle cover with a highlight effect, comprising a shell, wherein the shell comprises a connecting portion 1 and an earphone portion 2, the connecting portion 1 is connected to the earphone portion 2, the earphone portion 2 is used to assemble an external speaker, the connecting portion 1 is used to assemble external electronic components, the outer surface of the earphone portion 2 and the outer surface of the connecting portion 1 are respectively processed with a highlight film 3 through the NCL process, and the outer surface of the earphone portion 2 and the outer surface of the connecting portion 1 are back to back to each other.

[0018] In actual application, the shell is made of PC material. The NCL process is a process developed by Vivo for surface treatment of mobile phone shells made of PC material. The utility model applies the process to the earphone middle cover, so that the earphone middle cover, which is also made of PC material, not only has the original performance, but also improves the surface texture and brightness, so that the visual effect of the earphone middle cover is further improved, which is conducive to improving the user experience.

[0019] Specifically, the highlight film 3 includes a coating layer 31 and a metal paint layer. The coating layer 31 is arranged on the earphone part 2 and / or the connecting part 1 through a non-conductive electroplating process, and the metal paint layer is attached to the coating layer 31 through a spraying process. After the metal paint layer is attached to the coating layer 31, a pattern is formed through a laser engraving process.

[0020] That is, the NCL process mainly includes three steps: non-conductive electroplating, spraying and laser engraving. Polymer metal is deposited on the outer surface of the shell through non-conductive electroplating to form a coating layer 31, forming a microscopic high-gloss texture. This deposition technology can simulate the sandblasting anodizing and high-gloss metal effects of aluminum alloy, thereby highly simulating the gloss and texture of the metal; then the metal paint is adhered to the coating layer 31 through the spraying process to enhance the smoothness of the grip and make the shell feel close to metal; finally, the metal paint layer is partially removed by the laser engraving process to reveal the coating layer 31 under the metal paint layer, so that complex patterns and designs can be presented on the same plane.

[0021] Specifically, the highlight film 3 further includes a protective layer 33, which is disposed at one end of the metal paint layer away from the coating layer 31. The protective layer 33 is made of a conventional transparent wear-resistant material, and the process of attaching the protective layer 33 to the metal paint layer is a conventional method, such as pad printing, so that the protective layer 33 does not affect the gloss and texture of the highlight film 3 and will not be worn too quickly.

[0022] In this embodiment, the earphone part 2 is provided with a plurality of reinforcing ribs 21, the reinforcing ribs 21 are provided with positioning screw holes 22, and the earphone part 2 is also provided with positioning posts 23, which are used for plugging and positioning with the external earphone front shell / speaker. That is, the present invention improves the strength of the earphone part 2 by reinforcing ribs 21 to avoid deformation, and then realizes positioning with the corresponding component by positioning posts 23 to ensure the assembly effect; in addition, the present invention also has positioning screw holes 22, and the orientation of the positioning screw holes 22 is opposite to that of the positioning posts 23, so as to achieve the effect of fixing the external circuit board.

[0023] In this embodiment, a positioning seat 24 is provided at the connection between the connecting portion 1 and the earphone portion 2, and a positioning screw hole 22 is provided at the positioning seat 24; the bottom of the reinforcing rib 21 and the bottom of the positioning seat 24 are both fixed to the inner bottom wall of the earphone portion 2. That is, the positioning seat 24 has the effect of improving the strength of the connection between the connecting portion 1 and the earphone portion 2, so as to avoid the setting of the positioning screw hole 22 affecting the strength of the connection between the two.

[0024] In this embodiment, a limit seat 25 is provided in the earphone part 2, and a through hole 26 is provided in the limit seat 25, and a stopper 27 is provided on one side of the through hole 26. The through hole 26 is used to allow an external component to be inserted for positioning, and the external component may have a corresponding positioning portion, and after the positioning portion is inserted into the through hole 26, it is guided by the inclined surface thereof and passes through the stopper 27 on one side of the stopper 27, and prevents the stopper 27 from being inserted into the other side of the stopper 27, and then recovers its deformation and reliably contacts the other side of the stopper 27, so as to achieve the effect of preventing the earphone from falling off.

[0025] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
