[0002] The advantages of an external sound card mainly include improved sound quality, additional audio input and output interfaces, support for high-definition audio formats, noise reduction and echo cancellation, and suitability for music production and mixing. By providing higher sound quality, more interface options, support for advanced audio formats, noise reduction and echo cancellation technology, and professional music production functions, it brings users a richer and higher-quality audio experience. Since the external sound card is free from the limitations of circuit volume, it makes it possible to design more complex analog circuits and adopt better shielding designs, thereby greatly improving the sound quality.

[0003] Existing external sound card shells can usually be disassembled and installed, but in general, the upper cover of the shell is removed. When repairing, the upper cover needs to be opened to remove the external sound card. Since the sound card shell is in close contact with the sound card body, this method makes it easy for the external sound card body to get stuck inside the shell and difficult to remove, making it inconvenient to repair. Therefore, a shell connection structure for an external sound card is needed. Utility Model Content

[0025] Furthermore, an external sound card body 3 is provided inside the lower shell 1, a slot 5 is provided on the top of the upper cover 2, a receiving slot 12 is provided inside the lower shell 1, and a card slot 13 is provided on the surface of the limit plate 8. The card slot 13 is slidably connected with the card block 10. During installation, the slot 5 on the upper cover 2 is aligned with the corresponding component position on the external sound card body 3, and the two limit columns 7 at the bottom of the upper cover 2 are aligned with the two limit cylinders 9 on the lower shell 1, so that the upper cover 2 is installed from top to bottom inside the lower shell 1, and the limit columns 7 are slidably installed inside the limit cylinder 9. At the same time, the limit plate 8 contacts the card block 10, squeezing the card block 10 into the inside of the slide groove 15 until the card slot 13 on the limit plate 8 is aligned with the card block 10. The card block 10 returns to its original position under the action of the spring 14 and enters the inside of the card slot 13. The upper cover 2 is initially limited, and the two screw holes 6 opened on the upper cover 2 correspond to the screw holes 6 opened on the two card plates 11 respectively, and the two bolts 4 are installed in the corresponding screw holes 6, thereby realizing the installation of the upper cover 2.

The above structure can realize the rapid disassembly of the upper cover 2, and the surface of the upper cover 2 is curved. After the upper cover 2 is disassembled, more operating space can be leaked, which makes it easier to repair and replace the external sound card body 3. It is easy to use and solves the problem that when opening the upper cover to take out the external sound card, the external sound card body is easily stuck inside the shell and difficult to take out due to the close contact between the sound card shell and the sound card body, which is inconvenient for maintenance.

[0026] Working principle: During installation, align the slot 5 on the upper cover 2 with the corresponding component position on the external sound card body 3, align the two limit posts 7 at the bottom of the upper cover 2 with the two limit cylinders 9 on the lower shell 1, so that the upper cover 2 is installed from top to bottom inside the lower shell 1, and the limit post 7 is slidably installed inside the limit cylinder 9. At the same time, the limit plate 8 contacts the block 10, squeezing the block 10 into the inside of the slide groove 15 until the slot 13 on the limit plate 8 is aligned with the block 10. The block 10 returns to its original position under the action of the spring 14 and enters the inside of the slot 13, thereby realizing the preliminary limitation of the upper cover 2. After the upper cover 2 is preliminarily limited, the two screw holes 6 opened on the upper cover 2 correspond to the screw holes 6 opened on the two card plates 11 respectively, and the two bolts 4 are installed inside the corresponding screw holes 6, thereby realizing the installation of the upper cover 2. The same applies to disassembly.
