Waterproof sound-permeable membrane for phones and watches has excellent high temperature resistance, high temperature resistance, low temperature resistance, alkali resistance, anti-aging, anti-oxidation, electrically insulated wire, hydrophobicity, non-toxicity, and high lubrication , non-adhesive, weather-resistant, chemical-resistant and many other features.
In our lives, young people nowadays like to use Bluetooth headsets to listen to music, make calls, etc. If you observe Bluetooth headsets carefully, you will find that Bluetooth headsets have Lots of small holes. In fact, every small hole on the earphones has its own function. Some are sound holes and some are pressure relief holes. They can allow air to flow freely in the speaker to prevent pressure accumulation and cause changes in sound quality. Having a pressure relief hole can also Produces better sound quality and bass.
Waterproof sound-permeable membrane for phones and watchesThe pore size range is 0.02um-0.2um, and the porosity reaches more than 88%. In the state of water vapor, the water particles are very small, and these water particles can penetrate all the way down the capillary to the other side, causing vapor permeability. If water vapor condenses into water droplets, the particles will become larger, and the surface tension of the water droplets will act, and the water molecules will not be able to smoothly leave the water droplets, penetrate and reach the other side. In other words, this process can prevent The occurrence of water penetration makes the waterproof and breathable membrane truly have a waterproof function.
