There are two main materials of waterproof and sound permeable membrane: EPTFE and TPU.
Waterproof and sound permeable membrane is also known as waterproof and sound permeable membrane.
It is a kind of polyester material processed by special technology, which has strong stretchability, and is a good functional film material for sound transmission, and the waterproof and sound transmission film has a good waterproof and sound transmission effect. Sound transmission is transmitted by vibrating the thin film by sound waves. According to the electronic components of the application, there are speaker waterproof and sound permeable film, earpiece waterproof and sound permeable film, MIC waterproof and sound permeable film, speaker waterproof and sound permeable film, microphone waterproof and sound permeable film, walkie-talkie waterproof and sound permeable film, speaker waterproof and sound permeable film, receiver waterproof and sound permeable film, buzzer waterproof and sound permeable film, earphone waterproof and sound permeable film, smart wear waterproof and sound permeable film and other acoustic equipment used in waterproof and sound permeable film.
Waterproof and sound-permeable membrane.
The high standard of waterproof and sound permeable membrane can achieve IPX7 and IPX8 waterproof levels, and has good waterproof performance.

Waterproof sound permeable film, also known as WERS sound permeable film, is a kind of polyester material processed by a special process, with strong stretchability, is a good sound permeable material, from the name can be known to have a waterproof effect. Sound transmission is transmitted by the vibration of sound waves into the film. WERS sound-permeable film has the functions of waterproof and dustproof, sound permeability, low sound loss, etc., and is mainly used in acoustic equipment such as speakers, earpieces, mics, speakers, receivers, buzzers, etc.
The waterproof and sound-permeable membrane can reach IP67 waterproof, and it can be used normally after soaking in a water depth of 1 meter for 30 minutes!

One of the main differences between waterproof and sound permeable membranes is that waterproof and breathable membranes focus on air permeability, while waterproof and sound permeable membranes focus on sound permeability. Of course, in some specific cases, waterproof and sound permeable membranes can use expanded polytetrafluoroethylene (EPTFE) as a product to achieve waterproof and breathable, waterproof and sound permeable, dustproof and heat dissipation.
How PTFE waterproof, breathable and sound permeable membrane works.
In the state of water vapor (water vaporization), the water particles of PTFE waterproof breathable membrane are very small, and these water vapor particles can penetrate along the micropores of the waterproof membrane to the capillary (film) to the other side (the side that needs to be dissipated), and the phenomenon of ventilation occurs. If the water vapor condenses into water droplets, the particles will become larger, and the surface tension of the water droplets will act in it, and the water molecules will not be able to smoothly leave the water droplets and penetrate back to the original side, that is to say, such a process can prevent the occurrence of water penetration, that is, it can well isolate water and other liquids from the outside, so that PTFE waterproof and breathable membrane materials really have the function of waterproof and breathable.

The speaker waterproof and sound permeable membrane is made of EPTFE waterproof material, PTFE waterproof and sound permeable membrane is referred to as EPTFE film (Goel waterproof membrane), PTFE waterproof and breathable membrane is made of PTFE resin as raw material, and is formed into a microporous film with a diameter of 100-500 nanometers through some ordinary and special processing, and has more than 1 billion micropores per square centimeter, and the micropores are 700 times larger than water vapor molecules and 10,000 times smaller than water molecules. The Goel waterproof membrane not only allows air and water vapor to pass through the film freely, but also repels water from the membrane, effectively protecting the service life of electronic components.
Speaker waterproof and sound-permeable membrane.
Functions of the Goel Horn Waterproof and Sound Transparent Membrane:
1. The speaker waterproof and sound permeable membrane has good dustproof and waterproof, breathable and sound permeable performance, and the protection level reaches IP67 or above;
2. Balance pressure, quickly relieve pressure and exhaust, and maintain structural integrity;
3. The speaker waterproof sound permeable membrane has high-quality sound transmission performance, the sound loss is very small, and you can enjoy high-quality sound quality;
4. The speaker waterproof and sound permeable membrane can be made in a variety of shapes, sizes, thicknesses, etc. according to customer needs.

The speaker waterproof and sound permeable membrane is a new generation of waterproof material, which is made of TPU raw materials through a special process, which has the functions of waterproof and sound permeability, dustproof and oilproof, and is transmitted by vibration with good sound quality.
At present, domestic mobile phone speakers, earpieces, and speakers all use microphone waterproof and soundproof membrane, IP68 dustproof and waterproof function, because there are many holes on the mobile phone, and the waterproof structure design of each hole is different, so the mobile phone IP68 waterproof is only splash-proof, water-proof, and dustproof, of course, it is not excluded that some users can still use the mobile phone after washing it with water, but sometimes there is no need to take that risk, because the water damage of the mobile phone is not covered by the warranty, and the splash-proof, water-resistant, and dust-proof functions of the mobile phone will also extend with the use of time, the function is declining, so don't try it lightly.

Waterproof and sound-permeable membrane.
Key Benefits:
1.The waterproof and sound-permeable membrane uses sound transmission materials to ensure high-quality sound transmission.
2.The high air permeability of the waterproof and acoustic membrane membrane enables continuous internal and external gas exchange, effectively preventing the accumulation of harmful gases released by the battery.
3.The waterproof and acoustic membrane effectively relieves the stool to prevent condensation and fogging of the display.
4.The pressure inside and outside the housing is quickly equalized by means of a waterproof and acoustic membrane, reducing the stress on the housing seal.
5.The waterproof and acoustically permeable membrane protects the internal components from the pollutants and liquids used in everyday life.
6.The waterproof and sound permeable membrane is easy to install, which brings great convenience to the design and production.

IPX7 waterproof and sound-permeable membranes are generally made of TPU waterproof materials, which are mostly used for speakers, earpieces, speakers, mics, microphones, receivers, buzzers, etc. Now there are many people on the market who also call waterproof and sound permeable membranes, because both can be waterproof and sound permeable, they are different!
Weils has been in the field of waterproof for many years, and has been making waterproof and sound permeable membranes and waterproof and sound permeable membranes, and we have a better understanding of these materials!
IPX7 waterproof, generally 1 meter water depth 30 minutes after soaking can still be used normally.
Characteristics of waterproof and breathable membranes:
1. Air tightness: In 2005, the National Institute of Standards and Technology (NIST) released a report entitled "Investigation on the Impact of Air Tightness of Commercial Building Envelope on HVAC (Heating, Ventilation and Air Conditioning) Energy Utilization", which showed that the use of waterproof and breathable membranes can save up to 40% of the energy cost of heating and cooling in buildings without waterproof and breathable membranes. >>>More

Nayin is a method of taking numbers that is widely used in the ancient Han nationality, and its corresponding mathematics has been clearly stipulated by the sixty Jiazi Nayin, and its basic meaning is still elaborated by the "five elements". The "sound" of "Nayin" is the five tones determined by the ancient Han people according to different musical scales. The five tones are a highly abstract summary of the laws of natural sounds by the ancients. >>>More
