[0022] An embodiment of the present application provides a Bluetooth headset charging case 100 for realizing data connection between the Bluetooth headset charging case 100 and 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. The main board is also provided with a Bluetooth adapter module 130 electrically connected to the main control module 110, and the Bluetooth adapter module 130 has a BIS communication unit 131 and a CIS communication unit 132 built in. 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.

[0023] Specifically, the main control module 110, the charging module 120 and the Bluetooth adapter module 130 are all integrated on the main board of the Bluetooth headset charging compartment 100. The Bluetooth headset charging compartment 100 is directly connected to the external terminal through the interface, and there is no need to remove the Bluetooth adapter module 130, which is easy to operate and prevents loss. The Bluetooth adapter module 130 is built 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 a multi-person audio sharing scenario, the main control module 110 starts the BIS communication unit 131 through a control instruction to send audio data to multiple devices. When two-way transmission is required, such as a call, the main control module 110 can start the CIS communication unit 132 through a control instruction to establish a two-way communication connection with the audio playback terminal 200, so that the Bluetooth headset charging compartment 100 can be applied to more user scenarios, improving the degree of adaptation.

[0024] In some possible implementations, the main control module 110 is further used to: query the remaining power of the Bluetooth headset charging compartment 100 and the working status of the Bluetooth adapter module 130; When the remaining power is lower than the preset first threshold and the Bluetooth adapter module 130 is in the CIS communication unit 132 working mode, a working mode switching instruction is sent to the Bluetooth adapter module 130 to switch it from the current CIS communication unit 132 working mode to the BIS communication unit 131 working mode.

[0025] Specifically, CIS communication has high power consumption and consumes a lot of electricity when used for a long time. The main control module 110 can query the remaining power of the Bluetooth headset charging case 100 and the working status of the Bluetooth adapter module 130. When the power is low, the CIS communication unit 132 working mode is switched to the BIS communication unit 131 working mode to improve the battery life of the Bluetooth headset charging case 100 and the audio playback terminal 200.

[0026] In some possible implementations, the main control module 110 is further used for: Query whether the external device interface 150 of the Bluetooth headset charging compartment 100 is connected to an external terminal; If the external device interface 150 is connected to an external terminal, a BIS control instruction is sent to the Bluetooth adapter module 130 to start the BIS communication unit 131 to send a broadcast synchronization stream to at least one audio playback terminal 200 .

[0027] The main control module 110 can detect whether the peripheral 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 a PC, a game console or other device through a special audio cable, the main control module 110 controls the Bluetooth adapter module 130 to start the BIS communication unit 131 working mode, which simplifies the connection process and makes the operation more convenient.

[0028] In some possible implementations, starting the BIS communication unit 131 to send a broadcast synchronization stream to at least one audio playback terminal 200 specifically includes: Obtain the current working status of the Bluetooth adapter module 130; If the Bluetooth adapter module 130 is currently in the CIS communication unit 132 working mode, a stop working instruction is sent to the CIS communication unit 132, and after disconnecting the pairing with the current paired device, a start instruction is sent to the BIS communication unit 131; If the Bluetooth adapter module 130 is currently in an idle state, it directly sends a start instruction to the BIS communication unit 131 .

[0029] When the Bluetooth adapter module 130 switches to the BIS communication unit 131 working mode, the CIS communication unit 132 is stopped to reduce power consumption and improve the battery life of the Bluetooth headset charging case 100.

[0030] In some possible implementations, the main control module 110 is further used for: Query the working status of the Bluetooth headset charging compartment 100; The corresponding lighting effect indication instruction is sent to the status indication module 140 according to the working status.

[0031] Specifically, the status indication module 140 may be an LED light, which may display different lighting effects according to the working status of the Bluetooth headset charging compartment 100 , so as to facilitate the user to check the working status of the Bluetooth headset charging compartment 100 .

[0032] In some possible implementations, the Bluetooth adapter module 130 and the main control module 110 are connected via a communication interface, and the main control module 110 receives Bluetooth adapter module 130 and sends control instructions to the Bluetooth adapter module 130 via the communication interface. The communication interface is I2C or a single-line serial port.

[0033] This allows the Bluetooth adapter module 130 and the main control module 110 to communicate via a physical connection, thereby enhancing stability.

[0034] In some possible implementations, a USB switch 160 is provided between the peripheral interface 150 of the Bluetooth headset charging compartment 100 and the Bluetooth adapter module 130. The USB switch 160 is used to control the opening and closing of the USB interface signal to achieve the control of the connection and disconnection between the Bluetooth adapter module 130 and the external terminal.

[0035] In some possible implementations, the Bluetooth adapter module 130 is a Bluetooth dongle module, and the peripheral interface 150 includes at least a charging interface and an audio input interface, so that the peripheral interface 150 can be connected to an external power source to charge the battery module, and can also serve as an audio input interface of the Bluetooth adapter module 130. The peripheral interface 150 can use a USB Type-C interface, so that the Bluetooth headset charging case 100 can be charged and connected to an external terminal through the same interface.
