Embodiment Construction

[0020] The audio-frequency super-amphiphobic mesh composite film of the present invention is a compound of three-layer structure, the middle support layer is audio-frequency mesh, and the fiber layer and the super-amphiphobic layer are respectively distributed on both sides of the support layer.

[0021] The audio mesh is selected from the dust-proof mesh in the acoustic field used in the market. It is made of monofilament warp and weft through precision weaving. It has stable mechanical stability and can keep the warp and weft constant, the shape and size of the mesh aperture Invariant, this essentially non-deformable property is very important to maintain the mechanical stability of the composite structure. The selected audio mesh can be made of PET, PA, PP, PBT, PE, PEN, PEEK, cotton or several blends. The diameter of warp and weft is 10-150 microns, preferably 30-90 microns. The opening size is 10-300 microns, preferably 100-200 microns.

[0022] It should be pointed out...

Abstract

The invention provides an audio super-amphiphobic gauze composite film. The composite film is mainly applied to sound-transmitting and air-permeable hole channels of consumer electronics and intelligent household appliances. The audio super-amphiphobic gauze composite film is characterized in that the audio gauze is compounded with the fiber layer and the super-amphiphobic layer, so that the audio super-amphiphobic gauze composite film has excellent audio, efficient dustproof and super-amphiphobic properties.

Description

technical field [0001] The invention relates to an audio super amphiphobic mesh composite film, which is especially applied to but not limited to intelligent hardware acoustic components. [0002] technical background [0003] At present, electronic devices have brought convenience to people's lives and have become an indispensable part. Many of these products involve some essential vias, such as sound vias, ventilation vias. Such as mobile smart hardware mobile phones, watches, smart watches, bracelets, earphones, Bluetooth earphones, etc., as well as smart home appliances such as TVs, refrigerators, speakers, etc., and functional devices such as buzzers, temperature and humidity sensors, and sound alarms. In the long-term use process, it is necessary to protect the external pollution, such as dust, water, oil stains and other damage to sensitive components. [0004] The most commonly used means of protection is to use gauze, waterproof and breathable membrane to isolate t...
