In addition to water pressure resistant sound-permeable membranes, another application of expanded polytetrafluoroethylene membrane in the field of consumer electronics is MEMS acoustic membrane. This application Benefit from technological innovations in MEMS acoustic sensors (MEMS microphones). Before the advent of MEMS acoustic sensors, consumer electronics products such as mobile phones, computers, and game consoles were mainly equipped with ECM. However, because full-screen mobile phones pose challenges to mobile phone space design, consumer electronics products such as game consoles and wearables have high volume requirements for built-in accessories. With the trend of miniaturization, MEMS acoustic sensors are rapidly occupying the market due to their small size and good stability. At present, overall MEMS acoustic sensors have a high penetration rate in smartphones, laptops, headphones, automotive electronics and other fields, and they also have some application prospects in the Internet of Things.
Expanded PTFE membraneIn addition to being installed on cameras It can also be installed in consumer electronics such as smartphones, watches, bracelets, cameras, etc. to seal gaps and holes in the equipment, thereby making the electronic products reach IP67 and IP68 hydrophobic and dustproof levels, and allowing sound to pass through. The hydrophobic membrane remains in good condition. The film also protects against common liquids such as drinks, beer and coffee. It is often installed on the device port to maintain the sound quality. The product with adhesive patch is small in size and easy to install and use. It is an economical solution in limited space.
As a domestic enterprise in the field of expanded ePTFE microporous membranes, we use expanded polytetrafluoroethylene membrane materials to manufacture hydrophobic and breathable materials. product. The electronic hydrophobic sound-permeable membrane material we produce has extremely tight mesh micropores, with a pore diameter of about one 20,000th of a water droplet. It can block tiny water droplets and dirt particles as small as 0.1 microns in size, ensuring that electronic products will not be affected by The influence of foreign bodies.
