[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0014] Please see Figure 1 , Figure 1 This is a schematic diagram of the framework for a specific application of the battery-powered headset provided by this utility model. The battery-powered headset 10 is connected to an XR host 20. The XR host 20 is provided with a power interface 21. The battery-powered headset 10 is connected to the power interface 21 via a connecting cable. The battery-powered headset 10 includes a headset module 11 and a battery 12. The headset module 11 is connected to the power interface 21 via the connecting cable to receive digital audio signals. The battery 12 is connected to the power interface 21 via the connecting cable and is also connected to the headset module 11 to supply power to the XR host 20 and the headset module 11.

[0015] The power interface 21 of the XR host 20 is a connection interface for data transmission and power transmission, and has the functions of receiving external power, transmitting audio signals and transmitting power. The power interface 21 can be a USB-C interface. The battery headset 10 is equipped with a headset module 11, and the headset module 11 is connected to the power interface 21 of the XR host 20 through a connecting cable. Compared with the audio analog signal transmitted by the dedicated headset interface, the audio quality can be improved by receiving audio digital signals. Moreover, the battery 12 on the battery headset 10 not only supplies power to the headset module 11, but can also be connected to the power interface 21 through the connecting cable to supply power to the XR host 20, so that the power interface 21, together with the connecting cable, can transmit both audio digital signals and power supply current.

[0016] Preferably, the battery-powered earphone 10 further includes a headband, on which the earphone module 11 and the battery 12 are disposed. The headband has a host connection portion connected to each end of the XR host 20, and the headband is connected to the XR host 20 via the host connection portion. There can be two host connection portions, located at both ends of the headband, for detachable connection to the left and right ends of the XR host 20, thereby connecting the XR host 20 and the battery-powered earphone 10. The host connection portions ensure a stable connection between the XR host 20 and the headband, and facilitate convenient and quick assembly / disassembly.

[0017] Specifically, the built-in battery of the XR host 20 connected to the power interface 21 can supply power to the headphone module 11 through the power interface 21 and the connecting cable. The headphone module 11 is connected to the power interface 21 of the XR host 20 through the connecting cable. With the connecting cable, the XR host 20 can supply power to the headphone module 11 through the power interface 21. When the battery 12 is completely depleted or the battery level is lower than a preset value, the XR host 20 can supply power to the headphone module 11 to ensure the normal operation of the headphone module 11. This avoids the situation where the battery 12 fails to provide the headphone module 11 with the necessary power when the XR host 20 is working normally, thus ensuring the normal operation of the headphone module 11. This eliminates the need for the user to pause during use and connect an external power cable to charge the battery 12, improving the user experience.

[0018] Combination Figure 2Specifically, the battery-powered headset 10 also includes a main controller 13 and an audio power management module 14. The main controller 13 is connected to both the battery 12 and the audio power management module 14, and is used to detect the battery level of the battery 12 and control the operation of the audio power management module 14. The main controller 13 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, achieving 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 13 can use a CS32G020 chip.

[0019] Specifically, the headphone module 11 includes a headphone body 111 and an audio chip 112. The headphone body 111 is connected to the audio chip 112, and the audio chip 112 is connected to the power interface 21 via the connecting cable. The audio chip 112 is used to analyze and process the received audio digital signal and control the headphone body 111 to play audio. The headphone body 111 includes a left earphone and a right earphone. The audio power management module 14 is connected to the audio chip 112, the battery 12, and the power interface 21, so that the audio power management module 14 is connected to the corresponding XR host 20 via the power interface 21. The battery 12 is connected to the audio chip 112 via the audio power management module 14, and is used to control the battery 12 to supply power to the audio chip 112 or control the XR host 20 corresponding to the power interface 21 to supply power to the audio chip 112 according to the battery power information. The headphone body 111 is connected to the audio chip 112. The system switches power supplies by detecting the battery level of battery 12, ensuring smooth power switching and preventing the headphone module 11 from malfunctioning due to battery 12 power failure, thus improving the user experience. The audio chip 112 can be an AB136D.

[0020] Specifically, in this embodiment, the audio power supply management module 14 includes a battery power supply switch QS5 and an audio chip connection switch QS4. The input terminal of the battery power supply switch QS5 is connected to the battery 12, and the output terminal of the battery power supply switch QS5 is connected to the audio chip 112 through the audio chip connection switch QS4. The built-in battery of the XR host 20 is connected to the audio chip connection switch QS4 through the power interface 21 and the connecting cable. The main controller 13 is connected to the control terminal of the battery power supply switch QS5 to control the on / off state of the battery power supply switch QS5 according to the detected power information of the battery 12, thereby switching control of the power supply terminal to the headphone module 11 based on the power information of the battery 12 and in coordination with the battery power supply switch QS5.

[0021] Specifically, in this embodiment, the output terminal of the battery power supply switch QS5 is connected to the input terminal of the audio chip connection switch QS4 through the voltage regulator U7, the input terminal of the voltage regulator U7 is connected to the power interface 21, and the output terminal of the audio chip connection switch QS4 is connected to the audio chip 112.

[0022] Specifically, in this embodiment, the input terminal of the battery power switch QS5 is connected to the power interface 21 through the connecting line. When the power information of the battery 12 is not lower than the preset battery power conduction threshold and is lower than the preset headphone power required threshold, the corresponding XR host 20 can assist in supplying power to the audio chip 112, so that the XR host 20 and the battery 12 supply power to the audio chip 112 at the same time, ensuring the normal operation of the headphone module 11.

[0023] Specifically, in this embodiment, the battery-powered earphone 10 may also be provided with an earphone switching button. The earphone switching button is connected to the main controller 13, and the main controller 13 is connected to the control terminal of the audio chip connection switch QS4. It is used to control the on / off state of the audio chip connection switch QS4 according to the earphone switching signal of the earphone switching button, so as to control the start and stop of power supply to the audio chip 112. When power supply to the audio chip 112 is stopped, the audio chip 112 does not work. The main controller 13 feeds back the earphone switching signal to the XR host 20 through the connection line via the power interface 21. The XR host 20 transmits the audio digital signal to the audio playback module of the XR host 20 according to the received earphone switching signal and stops transmitting the audio digital signal to the power interface 21. The audio playback module of the XR host 20 analyzes and processes the received audio digital signal and transmits it to the speaker of the XR host 20 to switch to playing audio using the speaker of the XR host 20.

[0024] Based on the above design, during operation, the battery 12's power level is detected. When the battery 12's power level is greater than zero, the battery 12 is controlled to supply power to the corresponding XR host via the connection cable and power interface 21. The battery 12's power level is compared with a preset battery power supply conduction threshold. When the battery 12's power level is not lower than the preset battery power supply conduction threshold, the battery power supply switch QS5 is turned on, controlling the battery 12 to supply power to the audio chip 112. The battery 12's power level is compared with a preset headphone power requirement threshold. When the battery 12's power level is lower than the preset headphone power requirement threshold, the XR host 20 is controlled to supply power to the audio chip 112 through the turned-on battery power supply switch QS5, so that both the XR host 20 and the battery 12 supply power to the audio chip 112. When the battery 12's power level is lower than the preset battery power supply conduction threshold, the battery power supply switch QS5 is turned off, controlling the XR host 20 to supply power to the audio chip 112 through the turned-on sixth transistor QS6, ensuring smooth power supply switching.

The battery 12 is connected to the source of the battery power switch QS5 via the fourth diode D4. The power interface 21 is connected to the emitter of the sixth transistor QS6 via the connecting line and the third diode D3. The gate of the battery power switch QS5 is connected to the battery enable pin B2+EN of the main controller 13. The drain of the battery power switch QS5 is connected to the emitter of the sixth transistor QS6. The drain of the battery power switch QS5 is connected to the base of the sixth transistor QS6 and the input terminal of the voltage regulator U7 via the sixty-first resistor R61.

The battery-powered earphone is applied to the aforementioned XR device, and the control method of the battery-powered earphone includes the following steps:

[0028] Step S11: Power the XR host and headphone module via battery;

[0029] Step S12: Power the headphone module via the XR host;

By comparing the battery power information with the preset battery power supply threshold, it can be ensured that the battery can power the XR host and then power the headphone module at the same time, so as to determine whether to turn on the battery power switch and use the battery to power the audio chip.

[0036] When the battery level is not lower than the preset battery power supply threshold, the battery power supply switch is turned on to control the battery to supply power to the audio chip.

The preset headphone power requirement threshold can be the minimum value of the preset headphone power information required for normal operation. By comparing the electromagnetic power information with the preset headphone power requirement threshold, it can be determined whether the battery power information is sufficient to power the headphone module to work normally and whether the XR host needs to assist in powering the headphone module.

[0039] When the battery level is lower than the preset headphone power requirement, the XR host supplies power to the audio chip via the power interface and connection cable, so that both the XR host and the battery supply power to the audio chip, ensuring the normal operation of the headphone module.

[0040] Specifically, after the step of comparing the battery's power information with a preset battery power supply conduction threshold, the method further includes:

[0041] When the battery level is lower than the preset battery power supply threshold, the battery power supply switch is turned off, and the battery only supplies power to the XR host. This, in turn, controls the XR host to supply power to the audio chip, ensuring the normal operation of the headphone module.

[0042] In summary, the battery-powered headset of this invention, by incorporating a headset module connected to the power interface of the XR host via a connecting cable, improves audio quality by receiving digital audio signals compared to the analog audio signals transmitted through a dedicated headset interface.
