Abstract

The invention provides a waterproof and breathable composite membrane which comprises three layers of structures which are sequentially arranged and connected with one another. The front face and reverse face of a supporting layer are connected with a waterproof and breathable membrane and a protection layer through mucilage glue respectively, both the supporting layer and the protection layer are provided with corresponding holes, and the holes are only covered with the waterproof and breathable membrane. The waterproof and breathable composite membrane has the advantages that by the adoption of the technical scheme, the waterproof and breathable composite membrane is pasted to a through hole of an electronic product, and external water and dust can be effectively prevented from entering the electronic product while transfer of sound is not interfered with.

Description

technical field [0001] The invention belongs to the field of die cutting, and in particular relates to a waterproof and breathable composite film. Background technique [0002] With the progress of society, the use of electronic products has become more and more popular, and products such as recording pens, mobile phones, MP3 players, and earphones have entered thousands of households. Many electronic products have the function of sound transmission. In order to better record sound or transmit sound, some small holes are opened on the device, so that the sound can be smoothly transmitted from the outside to the inside of the device, or from the inside of the device. This common method can better transmit sound, but it also has a disadvantage. Because there is a through hole on the device, outside dust and moisture can easily enter the device through the through hole, especially when there is moisture from the outside When it is used, it will greatly affect the life of the e...
