With the development of science and technology, electronic products have gradually entered thousands of households and played a very important role in people’s lives. With the continuous development of electronic products, the water-repellent properties of electronic products are also constantly improving. People have put forward higher-level standards and requirements for the protection of electronic components. In the electronics industry, the application of hydrophobic sound-permeable membranes is also increasing. The more widespread it is. Especially for electronic communication equipment such as mobile phone headsets, it is necessary to ensure that the sound can be transmitted clearly while being protected.
Waterproof sound-permeable membrane for phones and watches is produced through calendering, extrusion, A microporous membrane made by biaxial stretching and other methods. The porosity can reach more than 85%, and the air can flow smoothly. The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above. Protect electronic instruments from becoming unusable due to moisture or water.
The waterproof sound-permeable membrane for phones and watches developed and produced can solve this problem very well. The pore size of the membrane is 0.1-1μm4, and the water droplet molecules At the same time, the porosity of the membrane is high, the air can circulate smoothly, the pressure is balanced, the rigidity of the membrane is good, the density is moderate, and the sound insulation loss is small. Waterproof sound-permeable membrane for phones and watches can also be widely used in digital cameras, walkie-talkies, smart watches, handheld ultrasound machines, handheld navigators, smart water cups, children’s smart early education machines, speakers, receivers, speakers, and microphones , MIC, receiver, buzzer, etc. Interested parties can enter the store for consultation.
