Problems solved by technology

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 It will greatly affect the life of the equipment, or even damage the product immediately
Even if it is not damaged, it will affect the quality of sound transmission

Abstract

A new waterproof breathable composite membrane includes a seven-layer structure, a protective layer A is connected with a support layer via an adhesive layer A, the support layer is connected with a waterproof breathable membrane through an adhesive layer B, the waterproof breathable membrane is connected with a protective layer B via an adhesive layer C, the protective layer A, the adhesive layer A, the support layer, the adhesive layer B, the adhesive layer C and the protective layer B are respectively provided with a corresponding hole, and the holes are only covered with the waterproof breathable membrane. The beneficial effects are that: the new waterproof breathable composite membrane can be pasted in a through hole of an electronic product to effectively prevent water and dust from outside to enter the electronic product without obstruction of transfer of sounds.

Description

technical field [0001] The invention belongs to the field of die cutting, and in particular relates to a novel 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...
