Mobile phone shell with dustproof net and manufacturing method thereof

Abstract

The invention discloses a mobile phone shell with a dustproof net and a manufacturing method thereof. the mobile phone shell comprises a body and filter net foam, wherein the body is a hard plastic material; a sound guide hole passes through the inner surface and the outer surface of the body; the inner surface of the body is provided with a concave cavity; the sound guide hole is communicated with the concave cavity; the filter net foam is embedded in the concave cavity and seals and covers the sound guide hole; the filter net foam comprises a first double-faced adhesive layer, a dustproof net, a second double-faced adhesive layer, a waterproof breathable film, a Mylar layer and a release film stacked sequentially from outside to inside. As the filter net foam with a specific structure is adopted and the waterproof breathable film adopting a specific formula is matched, the filter net foam is embedded in the concave cavity for long-time sealing and bonding, water can not penetrate to the concave cavity from the sound guide hole, good waterproof effects are realized, the waterproof grade can reach IP68, dust can be blocked on the dustproof net and can not enter the waterproof breathable film, cleaning is facilitated, and good sound guide effects can be kept.

Description

technical field [0001] The invention relates to the technology in the field of mobile phone shells, in particular to a mobile phone shell with a dust-proof net and a preparation method thereof. Background technique [0002] Mobile phones are an indispensable communication tool in today's society. With the continuous development of science and technology, people have put forward various requirements for the functions of mobile phones, especially the requirements for waterproof functions are becoming more and more stringent. Since sound needs to be exported or imported, sound guide holes are provided on various mobile phone casings. How to waterproof the sound guide holes is the key to realizing waterproofing of mobile phones. [0003] However, the sound guide holes on the current mobile phone casings are all effectively waterproofed, resulting in a poor waterproof effect of the mobile phone. Therefore, it is necessary to improve the current mobile phone casings. Contents of...
