Description

Technical Field

[0001] This utility model relates to the field of breathable membrane technology, and in particular to a microporous structure of a hydrophobic breathable membrane for acoustic components. Background Technology

[0002] Hydrophobic and breathable membranes in acoustic components are a key functional material designed to address the issue of maintaining sound transmission performance in electronic devices while ensuring they are waterproof and dustproof. They are primarily used to balance pressure and provide both dust and water resistance while maintaining sound transmission performance.

[0003] A search revealed Chinese Patent Publication No. CN214361120U, which includes a waterproof, breathable, and sound-permeable membrane, a rubber ring, and a connecting block. The rubber ring is fixedly connected to the waterproof, breathable, and sound-permeable membrane. An adhesive backing patch is fixedly connected to the bottom end of the rubber ring, and a protective pad is provided on the bottom end of the adhesive backing patch. The protective pad is fixedly connected to the adhesive backing patch. A pressure rod is provided on the right side of the top end of the rubber ring, and the pressure rod passes through the rubber ring. In this utility model, by using the pressure rod, connecting block, and tension spring, when it is necessary to peel off the protective pad on the adhesive backing patch during the use of the waterproof, breathable, and sound-permeable membrane, pressing the pressure rod on the top of the rubber ring will push the protective pad, opening it from the edge of the adhesive backing patch surface. The protective pad can then be peeled off the adhesive backing patch along the opened portion, making it convenient to remove the protective pad from the adhesive backing patch during use. However, the main structure of the waterproof and breathable membrane in this application is too simple, making installation and use inconvenient, and its waterproof, breathable, and sound-permeable functions are weak, resulting in poor practical effect.

The polymer material has good flexibility and weather resistance, which can protect the internal polyolefin microporous membrane 501 structure from damage.

[0040] It should be noted that an installation block 6 is fixedly installed on the outside of the hydrophobic and breathable membrane 5, and a positioning block 7 is fixedly connected to the outside of the installation block 6. Several positioning blocks 7 are provided. The size of the positioning block 7 is adapted to the inner wall size of the positioning groove 201. The positioning block 7 is movably connected to the positioning groove 201. The hydrophobic and breathable membrane 5 is positioned and locked into the positioning groove 201 by the positioning block 7 on the outside of the installation block 6. A locking groove 701 is provided on one side of the positioning block 7. The size of the locking groove 701 is adapted to the locking block 202. By rotating the installation block 6, the positioning block 7 is moved in the positioning groove 201, so that the locking groove 701 on one side of the positioning block 7 is aligned and locked with the locking block 202, thereby quickly positioning and locking the hydrophobic and breathable membrane 5.

The size of the limiting protrusion 801 is adapted to the positioning groove 201. The limiting protrusion 801 is movably connected to the positioning groove 201. The automatically reset limiting protrusion 801 is inserted into the positioning groove 201 to limit the connecting block 8.

The connecting block 8 is threadedly connected to the acoustic component 1. The connecting block 8 is rotated and fixedly connected to the acoustic component 1 through the thread.

[0042] Based on the above embodiments, it can be concluded that: the hydrophobic and breathable membrane 5 has a plurality of micropores on the surface of the polyolefin microporous membrane 501. The micropores are distributed in a rectangular array, and the diameter of the micropores is between 0.1 and several micrometers. The micropore size is larger than the diameter of water vapor molecules but smaller than the diameter of liquid water molecules, allowing water vapor molecules to pass through while blocking liquid water molecules, thus achieving a waterproof and breathable effect. A polymer material layer 502 is provided on the outside of the polyolefin microporous membrane 501. The polymer material has good flexibility and weather resistance, which can protect the internal polyolefin microporous membrane 501 structure from damage. The protective net 10 is placed on the surface of the hydrophobic and breathable membrane 5 to further protect the hydrophobic and breathable membrane 5. During installation, the hydrophobic and breathable membrane 5 is connected by the mounting block 6. The outer positioning block 7 is positioned and inserted into the positioning groove 201. By rotating the mounting block 6, the positioning block 7 is moved within the positioning groove 201, so that the locking groove 701 on one side of the positioning block 7 is aligned and engaged with the locking block 202, thereby quickly positioning and engaging the hydrophobic and breathable membrane 5. The protective cover 4 is fixed to the acoustic component 1 by rotating the internal thread of the connecting block 8. When the connecting block 8 is rotated and fixed in position, the synchronous ring 802 is reset by the reset spring inside the connecting block 8, which in turn drives the multiple limiting protrusions 801 of the synchronous ring 802 to reset and engage with the positioning groove 201. This fixes the connecting block 8 to prevent it from loosening its threaded connection with the acoustic component 1. At the same time, the limiting protrusions 801 limit the positioning block 7 in the positioning groove 201, further fixing the hydrophobic and breathable membrane 5.
