Abstract

The invention provides a waterproof breathable film, a mold and a manufacturing method thereof, and a loudspeaker. The mold of the waterproof breathable film comprises a substrate; a plurality of columns, wherein the plurality of columns are fixed on the first surface of the substrate and are arranged at intervals, and the section size of each column is in a micron order. The waterproof breathablefilm is prepared by adopting a mold through a mold casting method. 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 to ensure the strength of the waterproof breathable film, so that the waterproof depth of the waterproof breathable film is improved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of micro-speakers, and more specifically relates to a waterproof and gas-permeable membrane, a mold and a manufacturing method thereof, and a speaker with the waterproof and gas-permeable membrane. [0003] 【Background technique】 [0004] 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 transm...
