Generally speaking, it is difficult for some high-tech products such as phones, watches, and mobile phones to improve waterproof performance and audio performance at the same time. The key lies in how to achieve a good smoothness between the two. Waterproof sound-permeable membrane for phones and watches This product not only ensures reliable waterproofing, but also shows good audio performance.
Generally speaking, the waterproof, dustproof and sound-transparent products of mobile phone speakers, walkie-talkie speakers and other products are achieved by using sealing materials and waterproof materials to achieve. The smooth realization of the waterproof function is due to a thin layer of waterproof film attached to the speaker. Speaker waterproof sound-permeable membranes generally have the following characteristics:
Speaker waterproof sound-permeable membranes generally include white and black waterproof sound-permeable membranes. Waterproof sound-permeable membranes can be It is waterproof and can reduce sound loss to a very low level. 2. The waterproof and sound-permeable membrane for walkie-talkie speakers can be customized in size according to customer requirements to meet different product customization requirements. Waterproof and sound-permeable membrane for phones and watches The working principle can be divided into two types: microporous and hydrophilic groups. The waterproof and breathable membrane uses the former. Since the smallest diameter of water droplets is about 20 microns, and water vapor The diameter of the molecule is only about 0.0004 microns. There is a huge difference between the two diameters. Water vapor can pass through the microporous membrane through the principle of diffusion. Liquid water or water droplets cannot pass through due to the surface tension of liquid water or water droplets, which prevents water from passing through. The penetration occurs, making the breathable membrane waterproof.
It is a waterproof sound-permeable membrane for phones and watches manufacturer that specializes in R&D, production and sales. Our company is different from other manufacturers. Our company can according to the user’s requirements. By optimizing the key technical parameters of speed ratio, pressure ratio, operating temperature and other parameters, online control of air permeability, thickness and void ratio can be achieved based on the ratio and pore-forming medium to meet your different requirements.
