In what ways can sound permeable membranes be applied?

The sound permeable membrane new material can be used in smart electronic products (mobile phones, watches, wristbands, speakers, cameras, AR glasses, drones), new energy products (lithium batteries, fuel cells, new energy vehicles, solar power generation), biomedicine (bactericidal protection, liquid filtration), health and environmental protection (packaging, industrial filtration, explosion-proof pressure reduction, chemical raw materials purification screening), Chip products and manufacturing industry, so that it can play waterproof, breathable, sound permeability and corrosion resistance, high temperature, friction, insulation and other characteristics.
