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

The invention provides a composite material which comprises a three-layer structure. A waterproof and breathable material and a protection layer are bonded together through a bonding function layer, the protection layer is provided with a hole, and the hole is only covered with the breathable material. The composite material has the advantages that by the adoption of the technical scheme, the composite material is bonded to a through hole of an electronic product, external water and dust can be prevented from entering the electronic product, and transfer of sound is not hindered.

Description

technical field [0001] The invention belongs to the field of die cutting, and in particular relates to a composite material. 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 equipment, and even dam...
