[0036] An embodiment of the present application provides a Bluetooth headset charging case 100 for realizing data connection with an audio playback terminal 200. The Bluetooth headset charging case 100 includes a main board provided with a main control module 110 and a charging module 120. A Bluetooth adapter module 130 electrically connected to the main control module 110 is further provided on the main board, and the Bluetooth adapter module 130 is built-in with a BIS communication unit 131 and a CIS communication unit 132; the main control module 110 is used to send a control instruction to the Bluetooth adapter module 130, so that the Bluetooth adapter module 130 starts the BIS communication unit 131 to send a broadcast synchronization stream to at least one audio playback terminal 200 or starts the CIS communication unit 132 to send a connection synchronization stream to a single audio playback terminal 200.

[0037] Specifically, the main control module 110, the charging module 120, and the Bluetooth adaptation module 130 are all integrated on the main board of the Bluetooth headset charging case 100, and the Bluetooth headset charging case 100 is directly connected to an external terminal through an interface, without removing the Bluetooth adaptation module 130, which is convenient to operate and prevents loss. The Bluetooth adaptation module 130 is built-in with a BIS communication unit 131 and a CIS communication unit 132, which respectively support broadcast synchronization streams and connection synchronization streams. When it is necessary to transmit audio data to multiple audio playback terminals 200, such as in a multi-person audio sharing scenario, the main control module 110 starts the BIS communication unit 131 to send audio data to multiple devices through a control instruction. When two-way transmission is required, such as during a call, the main control module 110 can start the CIS communication unit 132 to establish a two-way communication connection with the audio playback terminal 200 through a control instruction, so that the Bluetooth headset charging case 100 can be applied to more user scenarios and the adaptation degree is improved.

[0038] In some possible implementation manners, the main control module 110 is further configured to: query the remaining power of the Bluetooth headset charging case 100 and the working state of the Bluetooth adaptation module 130;

[0039] When the remaining power is lower than a preset first threshold and the Bluetooth adaptation module 130 is in the working mode of the CIS communication unit 132, send a working mode switching instruction to the Bluetooth adaptation module 130 to switch it from the current working mode of the CIS communication unit 132 to the working mode of the BIS communication unit 131.

[0040] Specifically, the power consumption of CIS communication is relatively high, and the power consumed during long-term use is relatively high. The main control module 110 can query the remaining power of the Bluetooth headset charging case 100 and the working state of the Bluetooth adaptation module 130, and switch the working mode of the CIS communication unit 132 to the working mode of the BIS communication unit 131 when the power is low, so as to improve the battery life of the Bluetooth headset charging case 100 and the audio playback terminal 200.

[0041] In some possible implementation manners, the main control module 110 is further configured to:

[0042] Query whether an external terminal is connected to the peripheral interface 150 of the Bluetooth headset charging case 100;

[0043] If an external terminal is connected to the peripheral interface 150, send a BIS control instruction to the Bluetooth adaptation module 130 to start the BIS communication unit 131 to send a broadcast synchronization stream to at least one audio playback terminal 200.

[0044] The main control module 110 can detect whether an external device interface 150 is connected to an external terminal such as a PC or a game console. Specifically, when the Bluetooth headset charging case 100 is connected to devices such as a PC or a game console through a special audio cable, the main control module 110 controls the Bluetooth adapter module 130 to start the working mode of the BIS communication unit 131, which simplifies the connection process and makes the operation more convenient.

[0045] In some possible implementation manners, starting the BIS communication unit 131 to send a broadcast synchronization stream to at least one audio playback terminal 200 specifically includes:

[0046] Obtain the current working state of the Bluetooth adapter module 130;

[0047] If the Bluetooth adapter module 130 is currently in the working mode of the CIS communication unit 132, send a stop working instruction to the CIS communication unit 132, disconnect the pairing with the currently paired device, and then send a start instruction to the BIS communication unit 131;

[0048] If the Bluetooth adapter module 130 is currently in an idle state, directly send a start instruction to the BIS communication unit 131.

[0049] When the Bluetooth adapter module 130 is switched to the working mode of the BIS communication unit 131, stop the CIS communication unit 132 to reduce power consumption and improve the battery life of the Bluetooth headset charging case 100.

[0050] In some possible implementation manners, the main control module 110 is further configured to:

[0051] Query the working state of the Bluetooth headset charging case 100;

[0052] Send a corresponding light effect indication instruction to the status indication module 140 according to the working state.

[0053] Specifically, the status indication module 140 can be an LED lamp, which can display different light effects according to the working state of the Bluetooth headset charging case 100, facilitating the user to view the working state of the Bluetooth headset charging case 100.

[0054] In some possible implementation manners, the Bluetooth adapter module 130 and the main control module 110 are connected through a communication interface. The main control module 110 receives and sends control instructions to the Bluetooth adapter module 130 through the communication interface. The communication interface is I2C or a single-wire serial port.

[0055] The Bluetooth adapter module 130 and the main control module 110 can communicate through a physical connection, enhancing stability.

[0056] In some possible embodiments, a USB switch 160 is provided between the peripheral interface 150 and the Bluetooth adapter module 130 of the Bluetooth headset charging case 100. The USB switch 160 is used to control the opening and closing of the USB interface signal, so as to control the connection and disconnection between the Bluetooth adapter module 130 and an external terminal.

[0057] In some possible embodiments, the Bluetooth adapter module 130 is a Bluetooth dongle module, and the peripheral interface 150 at least includes a charging interface and an audio input interface, so that the peripheral interface 150 can not only be connected to an external power supply to charge the battery module, but also serve as the audio input interface of the Bluetooth adapter module 130. The peripheral interface 150 can adopt a USB Type-C interface, so that the Bluetooth headset charging case 100 can achieve charging and connecting to an external terminal through the same interface.

[0058] The embodiment of the present application also provides a Bluetooth headset device, including the Bluetooth headset charging case 100 in any of the above embodiments.

[0059] Those skilled in the art should be able to realize that in one or more of the above examples, the functions described in the embodiments of the present application can be implemented by hardware, software, firmware, or any combination thereof. When implemented using software, these functions can be stored in a computer-readable medium or transmitted as one or more instructions or codes on a computer-readable medium. The computer-readable medium includes computer storage media and communication media, where the communication media includes any medium that facilitates the transfer of a computer program from one place to another. The storage media can be any available medium that can be accessed by a general-purpose or special-purpose computer.
