Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0010] Please see Figure 1 , Figure 1 This is a schematic diagram of the framework of the headband device provided by this utility model in a specific application. The headband device 10 is connected to the XR host 20. The XR host 20 is provided with a transmission interface 21. The headband device 10 includes a transmission line, a battery 11, and a motherboard 12. The transmission line is used to connect to the transmission interface 21 to transmit audio digital signals and electrical signals. The battery 11 is connected to the transmission interface 21 through the transmission line to supply power to the XR host 20. The motherboard 12 is connected to the battery 11 and is connected to the transmission interface 21 through the transmission line to receive audio digital signals.

[0011] The transmission interface 21 can be a USB-C interface, and the motherboard 12 is a control circuit board. The motherboard 12 is connected to the battery 11 so that the battery 11 can supply power to the motherboard 12, and the motherboard 12 can also control the operation of the battery 11. The headband device 10 is equipped with a transmission line, a battery 11, and a motherboard 12. The battery 11 is connected to the transmission interface 21 of the XR host 20 through the transmission line to supply power to the XR host 20. The motherboard 12 is connected to the transmission interface 21 of the XR host 20 through the transmission line to receive audio digital signals, which can improve audio quality. It can simultaneously supply power to the XR host 20 and acquire audio, so that the headband device 10 transmits both power supply current and audio digital signals through the transmission line and the transmission interface 21 of the XR host 20, thereby expanding the functionality of the headband device 10.

[0012] Combination Figure 1 and Figure 2 Specifically, the motherboard 12 includes a charging interface 121 and a charging circuit module 122. The charging circuit module 122 is connected to the charging interface 121 and the battery 11 to charge the battery 11. The charging circuit module 122 is also connected to the transmission interface 21 via the transmission line to supply power to the XR host 20. The charging interface 121 can be connected to an adapter so that external power can be transmitted to the charging circuit module 122 via the adapter, charging the battery 11 of the headband device 10 and supplying power to the XR host 20.

[0013] Specifically, the motherboard 12 includes an audio module 123, which is connected to the transmission interface 21 via the transmission line. The audio module 123 analyzes and processes the received digital audio signal to obtain the corresponding audio, which is then played back by an audio playback device connected to the audio module 123. The audio module 123 may use an AB136D audio chip.

[0014] Preferably, the built-in battery of the XR host 20 connected to the transmission interface 21 can supply power to the audio module 123 through the transmission interface 21 and the transmission cable. The audio module 123 is connected to the transmission interface 21 of the XR host 20 through the transmission cable. With the help of the transmission cable, the XR host 20 can supply power to the audio module 123 through the transmission interface 21, which can ensure that the audio module 123 maintains normal operation during the connection between the headband device 10 and the XR host 20.

[0015] Specifically, the battery 11 is connected to the audio module 123 and can supply power to the audio module 123. When the battery 11 is completely depleted or its power level is below a preset value, the XR host 20 can supply power to the audio module 123 to ensure its normal operation. This prevents the headband device 10 from malfunctioning due to the battery 11 failing to provide the necessary power to the audio module 123 while the XR host 20 is operating normally. It also avoids the need for users to pause during use and connect an external adapter to charge the battery 11, thus improving the user experience.

[0016] Specifically, the headband device 10 further includes a player 13, which is connected to the mainboard 12 and is used to play audio. The mainboard 12 can be used to analyze and process the received audio digital signal to control the player 13 to play audio. Preferably, the mainboard 12 can control the player 13 to play audio by analyzing and processing the received audio digital signal through the audio module 123.

[0017] Specifically, the motherboard 12 also includes a main controller 124 and an audio power management module 125. The main controller 124 is connected to both the battery 11 and the audio power management module 125 to detect the battery level of the battery 11 and control the operation of the audio power management module 125. The main controller 124 can be an MCU that supports the PD (Power Delivery) protocol, enabling fast charging. The PD protocol is a power delivery protocol based on a USB Type-C interface. It uses a bidirectional communication mechanism, allowing devices to negotiate voltage and current for more flexible charging solutions. By using the Type-C interface, the PD protocol can achieve higher charging speeds and higher energy transfer efficiency. The main controller 124 can use a CS32G020 chip. The audio power supply management module 125 may include multiple switching transistors to control power supply through the on / off switching of corresponding transistors. These switching transistors control the power supply connection between the battery 11 and the audio module 123. Each switching transistor is connected to the main controller 124, so that the main controller 124 can control the operation of the audio power supply management module 125 by controlling the operation of the corresponding switching transistor. The main controller 124 is connected to the charging circuit module 122 and the audio module 123 to control their operation.

[0018] Specifically, the headband device 10 further includes a headband body, wherein the headband body is connected to two end portions corresponding to the two ends of the XR host 20, and the headband body is connected to the XR host 20 through the host connection portions. There can be two host connection portions, located at both ends of the headband body, for detachable connection to the left and right ends of the XR host 20, thereby connecting the XR host 20 and the headband device 10. By providing host connection portions, a stable connection between the XR host 20 and the headband can be achieved, and the assembly and disassembly operations are convenient and quick.

[0019] Preferably, the player 13 is integrated with the headband body. Of course, in some embodiments, the player 13 may be detachably connected to the headband body.

Alternatively, the battery 11 can be fixedly installed in the headband body. The battery 11 can be located on the outside of the headband body of the headband device 10 for easy maintenance and replacement, or it can be located inside the headband body to prevent damage from the external environment.

[0021] Preferably, the battery 11 can be snapped into the headband body via a snap-fit ​​structure.

[0022] Specifically, in this embodiment, there is one battery 11. Of course, in some embodiments, there may be two or more batteries 11 to meet different battery life requirements, and the number of batteries 11 supplying power to the XR host 20 and the audio module 123 can be set according to the requirements.

[0023] Specifically, the headband body may include a housing, and the battery 11 and the motherboard 12 are mounted on the housing.

[0024] In summary, the headband device of this utility model incorporates a transmission line, a battery, and a motherboard.
