The audio module 123 is connected to the transmission interface 21 through the transmission line to analyze and process the received audio digital signals to obtain the corresponding audio. The audio interface 14 is connected to the audio module 123 to transmit audio.

[0010] 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 power the motherboard 12, and the motherboard 12 can also control the operation of the battery 11. The audio module 123 can use an audio chip of model AB136D. The headband device 10 with an audio interface 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 via 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 via the transmission line to receive audio digital signals, which can improve audio quality and achieve simultaneous power supply and audio acquisition for the XR host 20. The headband device 10 with an audio interface transmits both power supply current and audio digital signals through the transmission line and the transmission interface 21 of the XR host 20. The motherboard 12 includes an audio module 123 and an audio interface 14 to process and analyze the received audio digital signals to obtain audio, which is then supplied to the headphones 30 for connection and playback. This expands the functionality of the headband device 10 with an audio interface, enabling simultaneous power supply and audio playback.

[0011] 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 with the audio interface and the XR host 20.

[0012] 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 with the audio interface 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.

[0013] Specifically, the headband device 10 with an audio interface further includes a structure for placement on the back of the user's head and a host connection strap for connecting the XR host 20 and the structure. The host connection strap includes two connecting straps located at the left and right ends of the XR host 20, respectively. One end of the connecting strap is connected to the structure, and the other end of the connecting strap is connected to a connector.

[0017] Specifically, the audio interface 14 is at least one of a Type-C interface or a 3.5mm headphone jack.

[0018] Specifically, the audio interface 14 is also used to transmit power signals. The motherboard 12 also includes a charging circuit module, which is connected to both the audio interface 14 and the battery 11 to charge the battery 11. The charging circuit module is also connected to the transmission interface 21 via the transmission line to supply power to the XR host 20. The audio interface 14 can be connected to the headphones 30 to play audio, or it can be connected to an adapter so that external power is transmitted through the adapter to the charging circuit module via the audio interface 14. The charging circuit module then charges the battery 11 of the headband device 10 with the audio interface and supplies power to the XR host 20, thus expanding the functionality of the audio interface 14.

[0019] Specifically, the motherboard 12 also includes a charging interface, and the charging circuit module is connected to both the charging interface and the battery 11 to charge the battery 11. The charging interface 121 can be connected to an adapter so that external power is transmitted through the adapter to the charging circuit module 122 via the charging interface 121, and the charging circuit module 122 charges the battery 11 of the headband device 10 with the audio interface and supplies power to the XR host 20.

[0020] The motherboard 12 may include a main controller, which can be an MCU, supporting the PD (Power Delivery) protocol to enable fast charging. The PD protocol is a power delivery protocol based on a USB Type-C interface. It employs a bidirectional communication mechanism, allowing devices to negotiate voltage and current for more flexible charging solutions.
