[0011] Optionally, the surface of the shell further has a connecting portion, which connects the inside and outside of the shell.

[0012] By adopting the above technical solution, the connecting portion communicates with the inside and outside of the installation shell, so that the equipment inside the shell can be connected to the outside of the shell.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By providing both a wireless connection slot and a wired connection bracket on the transmission base, the transmission base can be charged or output audio in both wireless and wired modes.

A wireless connection slot 4 and a wired connection frame 5 are provided on the surface of the shell 1. The wireless connection slot 4 can be used to place a wirelessly connected device for wireless charging or wireless audio transmission. The wired connection frame 5 has a receiving slot 51, which is used to support and place a wired connected device for wired charging or wired audio transmission. The wireless component 2 is installed on the inner side of the shell 1 and corresponds to the wireless connection slot 4. The wired component 3 is installed on the inner side of the shell 1 and corresponds to the wired connection frame 5. In addition, the surface of the shell 1 also has a connection port, which connects the inside and outside of the shell 1, so that the components installed in the shell 1 can be connected to the outside.

[0038] Reference Figure 3 and 4 The outer shell 1 includes a shell cover 11 and a shell bottom 12. A mounting block 14 is provided on the shell cover 11, and a mounting groove 15 corresponding thereto is provided on the shell bottom 12. By snapping the mounting block 14 into the mounting groove 15, the shell cover 11 and the shell bottom 12 can be conveniently fixed, thereby simplifying the assembly and disassembly process of the equipment. This design not only improves production efficiency, but also makes it convenient for users to repair and replace parts of the equipment. A bearing pad 17 is provided on the bottom side of the shell bottom 12. The bearing pad 17 not only plays an anti-slip role, but also provides additional protection when the equipment is placed to prevent scratches and wear. At the same time, the bearing pad 17 can also increase the friction between the equipment and the placement surface to ensure that the equipment remains stable during use.

[0039] Reference Figure 3 and 4 The wireless component 2 includes a transmission coil 21, a wireless circuit board 22, and a first receiver 23. The transmission coil 21 and the first receiver 23 are connected to the wireless circuit board 22. The transmission coil 21 is located on the back of the wireless connection slot 4 and uses electromagnetic field to receive and transmit wireless audio signals. The wireless circuit board 22 controls the output of the transmission coil 21. The first receiver 23 is exposed on the surface of the housing 1 and is used to receive wireless signals, allowing the wireless component 2 to be adapted for different control modes. The wired component 3 includes a transmission interface 31, a wired circuit board 32, a second receiver 33, a signal interface 34, an optical fiber interface 35, and a charging interface 36.

The second receiver 33 is also exposed on the surface of the housing 1 to receive signals to control the wired circuit board 32. The signal interface 34, optical fiber interface 35, and charging interface 36 are all mounted on the wired circuit board 32 and connected to the outside world through connectors.

[0040] Reference Figure 3 A heat sink 6 is further provided within the housing 1, on which the transmission coil 21, wireless circuit board 22, and wired circuit board 32 are all mounted. The heat sink 6 effectively absorbs the heat generated by the components within the transmission base and dissipates it through a larger heat dissipation area, thereby improving the operational performance of the transmission base.

[0041] Reference Figure 4 The wired circuit board 32 has a limiting opening 37, and the housing cover 11 is provided with a limiting protrusion 16. When the housing cover 11 and the housing base 12 are assembled together, the limiting protrusion 16 fits into the limiting opening 37, allowing the wired circuit board 32 to be installed quickly while also enhancing the structural stability of the device.

[0042] The implementation principle of the embodiment of the present application is as follows: depending on the usage requirements of the connected device, wireless audio signal transmission can be selected through the wireless connection slot 4 or wired audio signal transmission through the wired connection bracket 5. The transmission base can connect to an external device through the interface of the connection portion 13 to transmit audio information to the connected device. It can also connect to a wired device located on the wired connection bracket 5 through the transmission interface 31, and transmit information from the wired device to the transmission base, and then transmit audio signals to the wireless device, making the transmission base suitable for a wide range of scenarios.
