Waterproof, dustproof and shockproof telephone receiver net and manufacturing process thereof

Abstract

The invention discloses a waterproof, dustproof and shockproof telephone receiver net which comprise a foam layer, a first pressure-sensitive adhesive layer, a nylon net layer, a second pressure-sensitive adhesive layer and a release paper layer superposed in sequence, wherein the thicknesses of the foam layer, the first pressure-sensitive adhesive layer, the nylon net layer and the second pressure-sensitive adhesive layer are respectively 0.15-0.7 mm, 70-120 mum, 0.07-0.15 mm and 70-120 mum. The waterproof, dustproof and shockproof telephone receiver net has the advantages of has excellent waterproof, dustproof and shockproof properties, good adhesive property and high use safety. The invention also discloses a manufacturing process of the waterproof, dustproof and shockproof telephone receiver net.

Description

technical field [0001] The invention relates to electronic accessories, in particular to an earpiece net structure and a manufacturing process thereof. Background technique [0002] With the development of electronics and communication technology, there are many kinds of communication tools, such as mobile phones, microphones, speakers, earphones and other listening devices. In order to protect the internal circuit from environmental pollution and not affect the sound quality, it is generally necessary to set the A layer of handset mesh, refer to figure 1 Shown is the cross-sectional structure of a traditional earpiece net, which includes a nylon net layer 10, a pressure-sensitive adhesive layer 20, and a release paper layer 30 laminated in sequence, wherein the nylon net layer 10 can be made of nylon, nylon, polyester, etc. , used for waterproofing and dustproofing, the pressure-sensitive adhesive layer 20 has adhesive properties, and is used to bond the nylon mesh layer 1...

AI Technical Summary

Problems solved by technology

[0004] (1) The products currently on the market are all single finished products, such as dust-proof nets, waterproof non-woven fabrics, etc., which only have waterproof and dustproof performance, and require many application functions in the electronic field, such as earphones, mobile phone speakers, receivers, microphones, Speakers and other electronic products have different waterproof and dustproof application performances. In particular, some products have too high waterproof and dustproof grades, resulting in poor air permeability and inability to effectively dissipate heat. kind of accident;

[0005] (2) The adhesion of the existing waterproof and dustproof products on the market is not enough, and the original waterproof and dustproof performance is reduced or lost due to wrinkling and warping after a few days or weeks of use;

[0006] (3) Sometimes these electronic products are used during running and jumping. When the adhesion of the earpiece net is not enough, it will fall into the interior of the electronic product, causing interference and jamming of the mechanical transmission part and losing the product function. When it falls out, it may fall into the human body, causing accidents;

[0007] (4) Most of the earpiece nets currently on the market cannot protect the sound quality due to the improper configuration of the mesh of the dust-proof net. After a long period of use, the sound quality changes or the sound signal cannot be transmitted;

[0008] (5) In order to pursue the grand sound quality of the handset network, it is often at the expense of reducing the dustproof effect, thus losing the dustproof effect and not protecting the human body from vacuuming, and long-term use is harmful to the human body
