​What is the difference between breathable membrane and sound-permeable membrane?

2023-11-04

Learn the difference between waterproof and breathable membranes and waterproof and sound-permeable membranes today.


Waterproof and breathable membrane, also known as polytetrafluoroethylene waterproof membrane, is a polymer microporous filtration waterproof material made through a special process. It is more difficult to make than waterproof materials in other industries. The waterproof breathable film can be understood from the name. Know that this is a functional membrane that is both waterproof and breathable. The waterproof and breathable membrane of the waterproof membrane processing factory has the functions of dustproof, waterproof and breathable, air pressure balance, pressure relief and exhaust, heat dissipation and cooling. According to the electronic products used, there are waterproof and breathable membranes for electric toothbrushes, waterproof and breathable membranes for electric hair clippers, and beauty instruments. Waterproof and breathable film, waterproof and breathable film for mobile phone case, waterproof and breathable film for camera, waterproof and breathable film for outdoor flashlight, waterproof and breathable film for outdoor lamps, waterproof and breathable film for car lights, waterproof and breathable film for security camera, waterproof and breathable film for Bluetooth speaker, waterproof and breathable film for sensor film, electric shaver waterproof and breathable film, battery waterproof and breathable film, smart wearable waterproof and breathable film, etc.


Waterproof sound-permeable membrane, also called waterproof sound-permeable membrane, is a polyester material processed through a special process. It has strong stretchability and is a relatively good sound-permeable functional film material. As the name suggests, It can be seen that the waterproof sound-permeable membrane has waterproof and sound-permeable functions. Sound transmission is transmitted through the vibration of sound waves introduced into the film.

Waterproof sound-permeable membrane has the functions of waterproof and dustproof, sound transmission and low sound loss. According to the electronic components used, there are waterproof sound-permeable membranes for speakers, waterproof sound-permeable membranes for earpieces, MIC waterproof sound-permeable membranes, and waterproof and sound-permeable speakers. Membrane, microphone waterproof sound-permeable membrane, walkie-talkie waterproof sound-permeable membrane, speaker waterproof sound-permeable membrane, receiver waterproof sound-permeable membrane, buzzer waterproof sound-permeable membrane, earphone waterproof sound-permeable membrane, smart wearable waterproof sound-permeable membrane and other acoustic equipment waterproof and sound-permeable membrane.

Both films are currently used in mobile phones.

Waterproof and breathable membranes are mostly used in waterproof cases, and waterproof sound-permeable membranes are used in mobile phone speakers, earpieces, mics, etc. The purpose of waterproof breathable membranes and waterproof sound-permeable membranes in electronic products is to ensure that electronic products have good dustproof, waterproof, breathable and sound-permeable capabilities, while other functions are not affected or restricted in any way.


The main products of Xinzhenpin Company include breathable plugs, breathable membranes, water pressure resistant sound-permeable membranes, pressure relief valves, etc. Among them, breathable plugs and breathable membrane products are mainly used in automobile lights, wiper motors, ECUs, etc. to ensure the flow of air inside and outside the equipment. ;

Water pressure-resistant sound-transmitting membranes are mainly installed in consumer electronics such as smartphones and cameras to seal gaps and holes in the equipment; pressure relief valve products are mainly used in new energy power battery packs, etc. The above products have been used in automobiles, consumer electronics, etc. Electronics, new energy and other industries.
