Abstract

The invention provides a manufacturing method of a waterproof breathable film, and the method comprises the steps: providing a diaphragm with a plurality of through holes, and enabling the through holes to extend from the first surface of the diaphragm and penetrate through the diaphragm to the second surface of the diaphragm; and enabling the through hole in the diaphragm to be subjected to shrinkage cavity treatment. According to the invention, the through holes in the membrane can be subjected to shrinkage cavity treatment to obtain the waterproof breathable membrane. Therefore, the waterproof breathable film provided by the invention not only can ensure the ventilation and sound transmission quality, but also can have enough film thickness, so that the strength of the waterproof breathable film can be ensured, and the waterproof depth of the waterproof breathable film is improved.

Description

【Technical field】 [0001] The invention belongs to the field of waterproof and breathable membranes, and more specifically relates to a method for manufacturing a waterproof and breathable membrane. 【Background technique】 [0002] Many existing devices such as smartphones, tablets, and talking watches have waterproof requirements. In order to achieve a better waterproof effect, the best way is to make the device fully enclosed. With the widespread application of wireless charging and wireless earphones, there are fewer and fewer holes on devices such as smartphones, tablets, and talking watches, leaving only the microphone hole for sound pressure input and the hole for sound pressure. Speaker jack for voltage output. This is because in order to allow the sound to be transmitted better, the path of sound transmission cannot be completely closed. How to ensure that the incompletely closed sound transmission path can be effectively waterproof is a problem that needs to be sol...
