[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] It should be noted that the terms "including," "having," and any variations thereof in the embodiments and drawings of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0028] It should be understood that the terms "first," "second," and the like used herein may be used to describe various components, but these components are not limited by these terms. These terms are used solely to distinguish a first component from another component. For example, a first earphone may be referred to as a second earphone, and similarly, a second earphone may be referred to as a first earphone, without departing from the scope of this application. The first earphone and the second earphone are both earphones, but they are not the same earphone. Furthermore, it should be noted that the terms "plurality" and the like used in the embodiments of this application refer to two or more.

[0029] Figure 1 FIG. 1 is an application scenario diagram of a Bluetooth connection method in an embodiment. Figure 1 As shown, the headphone device 10 can establish a Bluetooth communication connection with one or more first terminal devices 20. The headphone device 10 may include but is not limited to headphones, in-ear headphones, earbud headphones, and earphones. Furthermore, the headphone device 10 may be a wireless Bluetooth headset, such as a True Wireless Stereo (TWS) Bluetooth headset. The first terminal device 20 may include but is not limited to wearable devices (such as bracelets, smart watches, smart glasses, etc.), car terminals, mobile phones, tablet computers, laptops, etc.

[0030] When the number of first terminal devices 20 maintaining Bluetooth connections with the headphone device 10 reaches the maximum number N of Bluetooth connections that the headphone device 10 can support, if the headphone device 10 receives a Bluetooth connection request sent by a second terminal device 30, the headphone device 10 is in a connection grabbing scenario, and the second terminal device 30 needs to grab a Bluetooth connection between the first terminal device 20 and the headphone device 10. The second terminal device 30 may include but is not limited to a wearable device, an in-vehicle terminal, a mobile phone, a tablet computer, a laptop computer, etc.

[0031] In related technologies, when the headphone device 10 is in a connection-grabbing scenario, the headphone device 10 needs to first disconnect the Bluetooth connection with a first terminal device 20 before it can respond to the Bluetooth connection request sent by the second terminal device 30, resulting in a slow speed for the second terminal device 30 to grab the connection with the headphone device 10, affecting the connection-grabbing efficiency.

[0032] The embodiments of the present application provide a Bluetooth connection method, apparatus, headphone device, and computer-readable storage medium, which can increase the connection speed of the second terminal device 30 to the headphone device 10 and improve the connection efficiency.

[0033] The earphone device 10 may include a first earphone 110 and a second earphone 120. Taking the earphone device 10 as a TWS earphone as an example, in some embodiments, the first earphone 110 and the second earphone 120 can distinguish between master and slave earphones. In the related art, taking the earphone device 10 being connected to a terminal device as an example, the master earphone of the first earphone 110 and the second earphone 120 establishes a Bluetooth connection with the terminal device, and the slave earphone establishes a Bluetooth connection with the master earphone. The slave earphone can obtain the connection information between the master earphone and the terminal device through the Bluetooth connection with the master earphone, so that the communication between the master earphone and the terminal device can be monitored in a monitoring manner, and the synchronization of the master and slave earphones can be achieved. As an implementation method, the master earphone can also establish a Bluetooth connection with the terminal device, and the master earphone can establish a Bluetooth connection with the slave earphone. After receiving the data sent by the terminal device, the master earphone forwards it to the slave earphone, and the synchronization of the master and slave earphones can be achieved. In the absence of conflict, the above-mentioned several Bluetooth connection methods can all be applied to the scheme of the Bluetooth connection method provided in the embodiment of the present application.

[0034] In an embodiment of the present application, when the headphone device 10 establishes Bluetooth connections with N first terminal devices 20 respectively, if a Bluetooth connection request sent by the second terminal device 30 is received, that is, the headphone device 10 is in a connection-grabbing scenario, a disconnection process can be performed through the first headphone 110, and the Bluetooth connection request can be processed by the second headphone 120 to establish a Bluetooth connection with the second terminal device 30. The disconnection process is used to disconnect the Bluetooth connection between the headphone device 10 and the target terminal device among the N first terminal devices 20. The first headphone 110 and the second headphone 120 perform the disconnection and connection establishment in parallel. The headphone device 10 does not need to wait for the Bluetooth connection with the target terminal device to be disconnected before responding to the connection request sent by the second terminal device 30. This can increase the speed of the second terminal device 30 in grabbing the connection with the headphone device 10 and improve the connection-grabbing efficiency.

[0035] It should be noted that Figure 1 Only the scenario in which the headphone device 10 can support establishing Bluetooth connections with two terminal devices is shown, that is, the headphone device 10 supports the "one-to-two" scenario, and the embodiment of the present application can also be applied to different scenarios in which the headphone device 10 supports "one-to-one", "one-to-three", "one-to-four"... etc. The maximum number of Bluetooth connections specifically supported by the headphone device is not limited in the embodiment of the present application.

[0036] like Figure 2 As shown, in one embodiment, a Bluetooth connection method is provided, which can be applied to the above-mentioned headphone device, and the headphone device can include a first headphone and a second headphone. The method can include the following steps:

[0037] Step 210: When the headset device establishes Bluetooth connections with N first terminal devices respectively, a Bluetooth connection request sent by the second terminal device is received.

[0038] In an embodiment of the present application, N can be the maximum number of Bluetooth connections supported by the headphone device, that is, the maximum number of terminal devices to which the headphone device can maintain Bluetooth connections at the same time. N can be an integer greater than or equal to 1, for example, N can be 1, 2, 3, 5, etc., which is not limited here.

[0039] It can be understood that the headset device establishes Bluetooth connections with the N first terminal devices respectively, which may mean that the headset device maintains Bluetooth connections with the N first terminal devices.

[0040] It can be understood that when the headphone device establishes Bluetooth connections with N first terminal devices respectively, it may include: when the headphone device establishes Bluetooth connections with N first terminal devices respectively, and the headphone device is in a connectable state. Among them, the headphone device being in a connectable state may refer to the headphone device being in page scan mode, and in page scan mode, it can receive Bluetooth connection requests sent by other terminal devices. Furthermore, the Bluetooth connection request may be a paging (page) data packet, and other terminal devices may use frequency hopping to send paging data packets to page the headphone device. The headphone device may scan (scan) the paging data packets sent externally at fixed intervals. If the headphone device scans the paging data packets sent by other terminal devices, it can be considered that the Bluetooth connection request has been received. For the specific process of Bluetooth connection, please refer to the provisions of the Bluetooth standard protocol.

[0041] In some embodiments, the second terminal device may be a terminal device that has not been paired with the headphone device. When the headphone device is in a pairing state, the pairing state may refer to the headphone device turning on the inquiry scan mode and the page scan mode. In the inquiry scan mode, the headphone device allows being scanned and searched by other terminal devices, and in the page scan mode, the headphone device allows being connected by other devices. That is, in the pairing state, the headphone device is in a discoverable state and a connectable state at the same time. The second terminal device can scan the headphone device and send a Bluetooth connection request to the headphone device to request a Bluetooth connection with the headphone device. It is understandable that if the second terminal device has not been paired with the headphone device, then a pairing operation will be performed during the process of establishing a Bluetooth connection.

[0042] In some embodiments, the second terminal device may also be a terminal device that has been previously paired with the headphone device. The second terminal device may send a Bluetooth connection request to the headphone device based on the stored device information corresponding to the headphone device to request to establish a Bluetooth connection with the headphone device. Since the pairing information such as the pairing key has been stored in the previous pairing, there is no need to pair again.

[0043] When the headset device establishes Bluetooth connections with N first terminal devices, the maximum number of Bluetooth connections that the headset device can support has been reached. If the headset device receives a Bluetooth connection request from a second terminal device, it needs to disconnect the Bluetooth connection with one of the first terminal devices before it can successfully establish a Bluetooth connection with the second terminal device. This is equivalent to the second terminal device preempting the Bluetooth connection between the first terminal device and the headset device. That is, when the headset device establishes Bluetooth connections with N first terminal devices, if the headset device receives a Bluetooth connection request from a second terminal device, the headset device is in a connection preemption scenario.

[0044] Step 220: Perform a disconnection process through the first headset, where the disconnection process is used to disconnect the Bluetooth connection between the headset device and a target terminal device among the N first terminal devices.

[0045] Step 230: Process the Bluetooth connection request through the second headset, so that the headset device establishes a Bluetooth connection with the second terminal device.

[0046] When the headphone device is in a connection-grabbing scenario, it is necessary to disconnect the Bluetooth connection with a first terminal device. In an embodiment of the present application, the disconnection process can be performed through the first headphone of the headphone device, and the Bluetooth connection request can be processed through the second headphone of the headphone device. The first headphone and the second headphone can perform disconnection and connection operations in parallel.

[0047] The first headset may determine a target terminal device from the N first terminal devices, and send a disconnection instruction to the target terminal device, where the disconnection instruction is used to disconnect the Bluetooth connection with the target terminal device.

[0048] In some embodiments, if N is 1, that is, the headset device establishes a Bluetooth connection with only one first terminal device, then the first terminal device is the target terminal device. If N is an integer greater than or equal to 2, that is, the headset device establishes a Bluetooth connection with multiple first terminal devices, then the first headset can select one of the multiple first terminal devices as the target terminal device.

[0049] Optionally, the target terminal device may be any first terminal device among the first terminal devices, and the first headset may randomly select the target terminal device from the N first terminal devices. As another embodiment, the target terminal device may also select the target terminal device from the N first terminal devices according to a preset selection rule. For example, the first terminal device with the lowest priority may be selected as the target terminal device based on the priority of each first terminal device, or the first terminal device with the lowest activity (i.e., the least amount of data transmitted) may be selected as the target terminal device, etc., but the present invention is not limited thereto.

[0050] The first headset can obtain the device identification of the target terminal device, which may include but is not limited to the MAC (Media Access Control) address of the target terminal device, and send a disconnect instruction to the target terminal device according to the device identification to disconnect the Bluetooth connection between the headset device and the target terminal device.

[0051] When the first earphone is disconnected, the second earphone can process the Bluetooth connection request sent by the second terminal device in parallel, and can respond to the Bluetooth connection request to establish a Bluetooth connection between the earphone device and the second terminal device, thereby reducing the time of switching devices.

[0052] In some embodiments, the headphone device may include a master headphone and a slave headphone. When the headphone device establishes a Bluetooth connection with N first terminal devices, the master headphone establishes a Bluetooth physical link with the N first terminal devices and can directly transmit data with the N first terminal devices. The slave headphone can monitor the Bluetooth physical link between the master headphone and the N first terminal devices, or the master headphone can synchronize data sent by the first terminal device to the slave headphone. The slave headphone does not directly connect to the N first terminal devices. The Bluetooth physical link may include, but is not limited to, physical links such as ACL (Asynchronous Connectionless).

[0053] Optionally, the above-mentioned first earphone can be the master earphone of the earphone device, and the second earphone can be the slave earphone of the earphone device. The first earphone can establish Bluetooth connections with N first terminal devices respectively, and a Bluetooth connection can be established between the first earphone and the second earphone. As an embodiment, if the first earphone receives data sent by any first terminal device, the first earphone sends the data to the second earphone through the Bluetooth connection with the second earphone, thereby realizing master-slave synchronization. As another embodiment, the first earphone can synchronize the connection information of each first terminal device to the second earphone through the Bluetooth connection with the second earphone, so that the second earphone monitors the Bluetooth connection between the first earphone and the N first terminal devices according to the connection information, thereby realizing master-slave synchronization.

[0054] When the earphone device is in a connection-grabbing scenario, the first earphone can directly disconnect the Bluetooth connection with the target terminal device and send a disconnection instruction to the target terminal device. The second earphone can establish a Bluetooth connection with the second terminal device based on the Bluetooth connection request sent by the second terminal device, and after successfully establishing the Bluetooth connection with the second terminal device, synchronize the connection information of the second terminal device to the first earphone, thereby switching the Bluetooth connection object of the second terminal device to the first earphone, that is, switching the Bluetooth connection between the second earphone and the second terminal device to the Bluetooth connection between the first earphone and the second terminal device.

[0055] Optionally, the first earphone can be a slave earphone of the earphone device, and the second earphone can be a master earphone of the earphone device. When the earphone device is in a connection-grabbing scenario, the first earphone can monitor the Bluetooth connection between the second earphone and the target terminal device and send a disconnect request to the target terminal device over the transmission channel between the second earphone and the target terminal device. The disconnect request can be used to trigger the disconnection of the Bluetooth connection between the target terminal device and the second earphone. The second earphone can process the Bluetooth request sent by the second terminal device and establish a Bluetooth connection with the second terminal device.

[0056] In some embodiments, establishing the Bluetooth connection mentioned above may include establishing a Bluetooth physical link, such as an ACL physical link.

[0057] In an embodiment of the present application, when the headphone device is in a connection grabbing scenario, the first headphone and the second headphone of the headphone device can perform the disconnection operation of the target terminal device and the Bluetooth connection operation with the second terminal device in parallel. The headphone device does not need to wait for the disconnection process to be completed before responding to the connection request sent by the second terminal device, which can increase the connection grabbing speed of the second terminal device to the headphone device and improve the connection grabbing efficiency.

[0058] like Figure 3 As shown, in another embodiment, a Bluetooth connection method is provided, which can be applied to the above-mentioned headphone device. The method may include the following steps:

[0059] Step 302: When the headset device establishes Bluetooth connections with N first terminal devices respectively, a Bluetooth connection request sent by a second terminal device is received.

[0060] The description of step 302 can refer to the relevant descriptions in the above embodiments, and will not be repeated here.

[0061] In some embodiments, the second terminal device may be a device that has not been paired with the headset device. When the headset device establishes Bluetooth connections with N first terminal devices, if the headset device enters the pairing state, in related technologies, the headset device will directly disconnect from at least some of the first terminal devices. Even if no second terminal device requests to connect to the headset device, the headset device and at least some of the first terminal devices remain disconnected, requiring the user to manually restore the Bluetooth connection.

[0062] In an embodiment of the present application, when the headphone device establishes Bluetooth connections with N first terminal devices respectively, the headphone device can enter the pairing state according to the pairing instruction and maintain the Bluetooth connection with the N first terminal devices. The headphone device is in the pairing state, and the inquiry scan mode and the page scan mode are turned on in the pairing state. The headphone device can be scanned by the second terminal device and the headphone device can receive the Bluetooth connection request sent by the second terminal device. The second terminal device can turn on the scanning mode and scan the surrounding Bluetooth devices. The second terminal device can send a scanning request (inquiry request) to the headphone device. The headphone device can receive the scanning request sent by the second terminal device through the first headset and / or the second headset, and send a scanning response (inquiry respond) to the second terminal device according to the scanning request.

[0063] Optionally, after the second terminal device receives the scan response, it can obtain the device information of the headphone device, such as the device name, MAC address, etc. of the headphone device, and display the device information. The user of the second terminal device can perform a selection operation on the device information to trigger the second terminal device to connect to the headphone device. After the second terminal device receives the selection operation, it can send a Bluetooth connection request to the headphone device based on the device information of the headphone device. After the headphone device receives the Bluetooth connection request, it disconnects the headphone through the first headphone and processes the Bluetooth connection request through the second headphone. The headphone device does not need to disconnect the Bluetooth connection between the headphone device and at least part of the first terminal device after entering the pairing state. This can avoid the situation where there is no second terminal device requesting to establish a Bluetooth connection with the headphone device, resulting in the user having to manually restore the Bluetooth connection, which is more in line with user needs.

[0064] In some embodiments, the headphone device enters the pairing state according to the pairing instruction, including but not limited to any of the following methods:

[0065] Method 1: Receive a pairing command from the headphone charging box and enter the pairing state according to the pairing command. The headphone device can be a wireless Bluetooth headphone and can be equipped with a headphone charging box that matches the headphone device and can be used to charge the headphone device. When the headphone device needs to enter the pairing state, the user can place the first and second headphones in the headphone device into the headphone charging box. The headphone charging box can send a pairing command to the first and / or second headphones placed in the headphone charging box based on the detected pairing operation.

[0066] Optionally, the earphone charging box may be provided with a pairing button, and the pairing operation may be a pressing operation on the pairing button. The pairing operation may also be an opening operation of the earphone charging box. When the first earphone and the second earphone are placed in the earphone charging box, if the opening operation is detected, the earphone charging box sends a pairing instruction to the first earphone and / or the second earphone placed in the earphone charging box.

[0067] Method 2: Receive a pairing instruction from any first terminal device and enter the pairing state according to the pairing instruction. The user can control any first terminal device that has established a Bluetooth connection with the headset device to put the headset device into the pairing state. The first terminal device can respond to the user-triggered operation to start the pairing state and send a pairing instruction to the headset device via the Bluetooth connection.

[0068] In one embodiment, the operation of activating the pairing state may include triggering a pairing option displayed on the first terminal device. The first terminal device may display a management interface for the headphone device, which may include a pairing control. If the first terminal device detects a triggering operation for the pairing control, it may send a pairing instruction to the headphone device via a Bluetooth connection to control the headphone device to enter the pairing state.

[0069] For example, Figure 4 FIG. 1 is a schematic diagram of an interface of a first terminal device in an embodiment. Figure 4 As shown, the first terminal device 20 can display a Bluetooth headset and a pairing control 202 , and the user can click the pairing control 202 , and the first terminal device 20 can send a pairing instruction to the headset device 10 .

[0070] As another implementation, the pairing operation may also be a preset touch operation, gesture operation, voice control operation or other interactive operations, which may be set according to actual needs. The embodiment of the present application does not limit the specific operation method of the pairing operation.

[0071] In an embodiment of the present application, a first terminal device that establishes a Bluetooth connection with the headphone device is used to control the headphone device to enter a pairing state. There is no need to place the headphone device in a headphone charging box, which is more convenient and efficient.

[0072] Method 3: Respond to the detected pairing trigger operation, generate a pairing instruction, and enter the pairing state according to the pairing instruction.

[0073] In some embodiments, the headphone device may be provided with one or more different sensors, such as a distance sensor, a touch sensor, a pressure sensor, a temperature sensor, etc., but not limited thereto. The operation mode of the pairing trigger operation may be pre-set, such as a press operation, a touch operation, a distance sensing operation, etc. The headphone device may collect user interaction data through the sensor, such as the touch duration, touch position, touch frequency and other information through the touch sensor, and the pressing force, pressing duration, pressing frequency and other information through the pressure sensor, and determine whether the user interaction data matches the preset pairing trigger operation mode. If it matches, the detected pairing trigger operation may be determined, a pairing instruction may be generated and the pairing state may be performed. The user can control the headphone device to enter the pairing state by directly interacting with the headphone device, without having to put the headphone device into the headphone charging box, which is more convenient and faster and improves efficiency.

[0074] It should be noted that other methods may also be used to trigger the headphone device to enter the pairing state, and are not limited to the above methods. The embodiments of the present application do not limit this.

[0075] In other embodiments, the second terminal device may be a device that has been paired with the headphone device. The headphone device may be in a connectable state (i.e., page scan mode is turned on), and can receive Bluetooth connection requests sent by other electronic devices to the headphone device. The second terminal device may store a connection record of the headphone device, and the connection record may include but is not limited to some or all of the following information: the MAC address of the headphone device, pairing information (such as a key, pairing code, etc.), etc. The second terminal device may send a Bluetooth connection request to the headphone device based on the connection record. For the specific Bluetooth connection process, please refer to the corresponding Bluetooth protocol.

[0076] In other embodiments, when N is greater than 1, the headphone device is in a connectable state. The connectable state may be that the headphone device is in page scan mode. It is understandable that when N is greater than 1, that is, when the headphone can support simultaneous connection to two or more terminal devices (i.e., one-to-many), the headphone device can be controlled to be in a connectable state during use (such as when the headphone device is not in a charging state), so that the Bluetooth connection request of the second terminal device can be accepted, thereby improving the operational convenience of the one-to-many solution. It is understandable that the headphone device is in a connectable state, which may be that one of the headphones is in a connectable state, or both headphones are in a connectable state.

[0077] Step 304: Perform a disconnection process corresponding to the target terminal device through the first headset to disconnect the Bluetooth connection with the target terminal device.

[0078] Step 306: Process the Bluetooth connection request through the second headset and establish a Bluetooth connection with the second terminal device.

[0079] When the headphone device establishes Bluetooth connections with N first terminal devices respectively, if the headphone device receives a Bluetooth connection request sent by the second terminal device, the first headphone can be used to disconnect the target terminal device among the N first terminal devices, and the second headphone can be used to perform the disconnection and connection operations in parallel in the Bluetooth connection request.

[0080] In some embodiments, before performing the disconnection processing corresponding to the target terminal device through the first headset, it may also include: determining the target terminal device among the N first terminal devices.

[0081] For example, the first headset may select a target terminal device from N first terminal devices and perform a disconnection process corresponding to the target terminal device. In some embodiments, the first headset may select a first terminal device whose priority meets a priority condition from the N first terminal devices as the target terminal device based on the priority of each first terminal device.

[0082] The first headset may obtain the priority corresponding to each first terminal device with which a Bluetooth connection is established. Optionally, the priority of each first terminal device may be determined based on a device status parameter of each first terminal device. The device status parameter may include, but is not limited to, one or more of a service data output parameter, a sequence parameter for indicating the order in which Bluetooth connections are established with the headset device, a device type parameter, a device remaining battery parameter, and a historical connection frequency.

[0083] The service data output parameter may be used to indicate whether the first terminal device is currently outputting service data to the headset device via a Bluetooth connection. The priority of the first terminal device currently outputting service data to the headset device may be higher than the priority of the first terminal device currently not outputting service data to the headset device.

[0084] The sequence parameter can be used to characterize the order of establishing Bluetooth connections with the headphone device. As an embodiment, the first earphone can store the connection time when each first terminal device most recently established a Bluetooth connection with the headphone device, and determine the connection duration of each first terminal device based on the connection time corresponding to each first terminal device. The connection duration is the time from the connection moment to the current moment. The sequence parameter of each first terminal device can be determined based on the connection duration of each first terminal device. The longer the connection duration, the higher the order indicated by the sequence parameter, which means that the first terminal device establishes a Bluetooth connection with the headphone device sooner.

[0085] As another embodiment, the first headset may also establish a connection queue, and the device information of each first terminal device may be stored in the connection queue in the order in which the first terminal device establishes a Bluetooth connection with the headset device. The first terminal device that is ranked earlier in the connection queue indicates that the first terminal device established a Bluetooth connection with the headset device earlier. Optionally, the first terminal device that establishes a Bluetooth connection with the headset device earlier may have a lower priority.

[0086] The device type parameter can be used to characterize the device type of the first terminal device, which may include but is not limited to mobile phones, smart watches, wristbands, smart home devices, etc. The priority level corresponding to each device type can be pre-set. The first headset can determine the device type of each first terminal device based on the device type parameter of each first terminal device and obtain the priority level corresponding to the device type.

[0087] The device remaining power parameter can be used to characterize the current remaining power of the first terminal device. The priority of the first terminal device with a large device remaining power can be higher than the priority of the first terminal device with a small device remaining power.

[0088] The historical connection frequency can be used to characterize the historical connection status of the first terminal device and the headphone device. The historical connection frequency can be the connection frequency in the past period of time (such as the past week, the past month), etc. The first headset can store the connection status data of each terminal device and the headphone device. The connection status data may include the device information, connection time, connection duration, etc. of each terminal device. The first headset can count the historical connection frequencies of the N first terminal devices currently connected to the headphone device in the past period of time based on the stored connection status data. The priority of the first terminal device with a high historical connection frequency may be higher than the priority of the first terminal device with a low historical connection frequency.

[0089] The first headset can determine the priority corresponding to each first terminal device based on one or more device status parameters of each first terminal device. If the priority corresponding to each first terminal device is determined based on multiple device status parameters, a weight can be assigned to each device status parameter. Taking device A in the first terminal device as an example, device A can be any first terminal device. The benchmark priority corresponding to each device status parameter can be determined based on each device status parameter of device A. For example, the service data output parameter of device A is 1, indicating that service data is currently being output to the headset device, then the benchmark priority corresponding to the service data output parameter can be 4; the device remaining power parameter of device A indicates that the current remaining power of device A is greater than 50%, then the benchmark priority corresponding to the device remaining power can be 2, etc. Then, based on the benchmark priorities corresponding to each device status parameter of device A and the assigned weights of each device status parameter, a weighted sum calculation or a weighted average calculation can be performed to obtain the priority corresponding to device A.

[0090] It should be noted that the method of determining the priority of each first terminal device is not limited to the above-mentioned methods. For example, the priority rules can also be set directly. The first terminal device that is currently outputting service data to the headphone device has the highest priority. Among the first terminal devices that are not currently outputting service data to the headphone device, the first terminal device with the lowest remaining power has the lowest priority. Based on the priority rules and the device status parameters of each first terminal device, the priority of each first terminal device can be determined.

[0091] The first earphone selects the first terminal device whose priority meets the priority condition from N first terminal devices as the target terminal device. Optionally, the priority condition may include any one of the priority lower than the priority threshold, the lowest priority, etc. Furthermore, the first earphone may directly select the first terminal device with the lowest priority as the target terminal device, or may first select the first terminal device with a priority lower than the priority threshold. If there are multiple first terminal devices with priorities lower than the priority threshold, one of them may be randomly selected as the target terminal device, or the first terminal device with the lowest priority may be selected as the target terminal device. Determining the target terminal device based on the priority of each first terminal device can make the target terminal device for disconnecting the Bluetooth connection more in line with user needs, and can reduce the adverse effects of disconnecting the Bluetooth connection on the user's normal use.

[0092] It should be noted that the priority of each first terminal device can change according to specific circumstances and is not necessarily fixed. It is understandable that if the priority of a first terminal device changes before the headset device receives a Bluetooth connection request, the target terminal device will be selected according to the latest priority of each first terminal device when the Bluetooth connection request is received.

[0093] For example, when the headset device receives a Bluetooth connection request, if none of the first terminal devices transmits service data to the headset device, the first terminal device A that is connected first can be disconnected first according to the Bluetooth connection order of each first terminal device. If the headset device enters the pairing state, if the first terminal device A transmits service data (such as voice data, audio data, etc.) to the headset device before the headset device receives the Bluetooth connection request, then the priority of the first terminal device A changes. At this time, if the headset device receives a Bluetooth connection request, it will not disconnect the Bluetooth connection with the first terminal device A. At this time, which first terminal device is disconnected is determined according to the set priority rules. It can be seen that the headset device no longer disconnects when entering the pairing state, but disconnects after receiving the Bluetooth connection request, which largely guarantees the user's use of the headset. The use of the first headset and the second headset for parallel processing further shortens the speed of terminal device switching and improves the user experience.

[0094] After determining the target terminal device, the first headset may send a disconnect instruction to the target terminal device to terminate the Bluetooth connection with the target terminal device. Alternatively, the second headset may determine the target terminal device from N first terminal devices, and then send the device identifier of the target terminal device to the first headset, which then triggers the first headset to terminate the Bluetooth connection with the target terminal device.

[0095] While the first headset is disconnecting, the second headset can concurrently process a Bluetooth connection request from the second terminal device. In one embodiment, the second terminal device may not have been paired with the headset. The second headset can respond to the Bluetooth connection request and establish a Bluetooth connection with the second terminal device. During the Bluetooth connection establishment process, the second headset and the second terminal device are paired. This pairing process may include exchanging pairing codes and agreeing on a key between the two parties to ensure transmission security.

[0096] As another implementation, the second terminal device may be a terminal device that has been paired with the headphone device. The second headphone may respond to the Bluetooth connection request sent by the second terminal device and establish a physical link such as an ACL link with the second terminal device. In this case, since the second terminal device already has the pairing information of the headphone device, no further pairing is required.

[0097] Step 308: Synchronize the disconnection information of the target terminal device to the second headset through the first headset.

[0098] Step 310: Synchronize the connection information of the second terminal device to the first headset via the second headset.

[0099] Optionally, the first headset may be the master headset and the second headset may be the slave headset. After the first headset completes the disconnection process, the first headset may synchronize disconnection information to the second headset, where the disconnection information may include at least device information of the target terminal device that disconnected the Bluetooth connection. The second headset may no longer monitor the Bluetooth connection between the target terminal device and the first headset.

[0100] After the second earphone successfully establishes a Bluetooth connection with the second terminal device, the second earphone can synchronize the connection information of the second terminal device to the first earphone. The connection information may include but is not limited to frequency hopping information, channel information, clock information, etc.

[0101] In one embodiment, after the connection information of the second terminal device is synchronized to the first earphone through the second earphone, the Bluetooth connection object of the second terminal device can be switched from the second earphone to the first earphone, and the second earphone monitors the Bluetooth connection between the first earphone and the second terminal device; or, after the second earphone synchronizes the connection information of the second terminal device to the first earphone, the Bluetooth connection object of the second terminal device can be switched from the second earphone to the first earphone, and the first earphone synchronizes the data transmitted between the second terminal device and the second earphone.

[0102] After obtaining the connection information, the first earphone can directly transmit data with the second terminal device based on the connection information. The physical link between the second earphone and the second terminal device is transitioned to the physical link between the first earphone and the second terminal device, and the Bluetooth connection object of the second terminal device is switched from the second earphone to the first earphone. The second earphone can monitor the physical link between the first earphone and the second terminal device, or the first earphone can forward the data transmitted between the first earphone and the second terminal device to the second earphone to achieve master-slave synchronization. Through the synchronization of information between earphones, all terminal devices that establish a Bluetooth connection with the earphone device can use the first earphone (i.e., the master earphone) to connect and the second earphone (i.e., the slave ear) to monitor or receive the data forwarded by the first earphone, which is more convenient for management of connected terminal devices and data transmission.

[0103] Figure 5A FIG. 1 is an interactive sequence diagram of a Bluetooth connection method in one embodiment. Figure 5A As shown, the headset device can be a device that supports Bluetooth "one to two", and the headset device can establish Bluetooth connections with terminal device A and terminal device B respectively. The headset device is in a connectable state (in page scan mode), and terminal device C can be a device that has been paired with the headset device. Then, terminal device C can send a Bluetooth connection request to the headset device based on the previously stored information of the headset device. After the headset device receives the Bluetooth connection request sent by terminal device C, the first headset can connect to the target terminal device (for example, Figure 5AThe second headset can process the Bluetooth connection request. After the first headset disconnects from the target terminal device, the first headset can synchronize the disconnection information to the second headset. After the second headset successfully establishes a Bluetooth connection with terminal device C, the second headset can synchronize the connection information to the first headset, achieving information synchronization and switching the Bluetooth connection target of terminal device C from the second headset to the first headset.

[0104] Figure 5B FIG. 1 is an interactive sequence diagram of a Bluetooth connection method in another embodiment. Figure 5B As shown, the earphone device may be a device that supports Bluetooth "one to two", and the earphone device may establish Bluetooth connections with the terminal device A and the second device B respectively. Terminal device C may be a device that has not been paired with the earphone device, and the earphone device may enter the pairing state, and maintain Bluetooth connections with terminal device A and terminal device B before entering the pairing state. Terminal device C may send a scan request to the earphone device, and after receiving the scan request, the earphone device may send a scan response to terminal device C through the first earphone or the second earphone. In the pairing state, the earphone device is in inquiry scan and page scan modes at the same time. When terminal device C determines that it needs to establish a Bluetooth connection with the earphone device, it may send a Bluetooth connection request to the earphone device. After the earphone device receives the Bluetooth connection request sent by terminal device C, the first earphone may establish a connection with the target terminal device (for example, Figure 5B The second headset may process the Bluetooth connection request, establish a Bluetooth connection with the target terminal device, and pair with the terminal device C during the Bluetooth connection process. After the first headset disconnects the Bluetooth connection with the target terminal device, the first headset may synchronize the disconnection information to the second headset. After the second headset successfully establishes a Bluetooth connection with the terminal device C, the second headset may synchronize the connection information to the first headset, thereby achieving information synchronization and switching the Bluetooth connection target of the terminal device C from the second headset to the first headset.

[0105] In some embodiments, after the Bluetooth connection object of the second terminal device is switched from the second headset to the first headset, a Bluetooth physical link is established between the first headset and the second terminal device. Furthermore, the first headset can further establish A2DP (Advanced Audio Distribution Profile, Bluetooth audio transmission model agreement), HFP (Hands-free Profile) and other service connections with the second terminal device based on the Bluetooth physical link, so that the second terminal device can transmit audio data, voice data and other service data to the first headset.

[0106] In an embodiment of the present application, when a second terminal device preempts the Bluetooth connection to the headset device, the disconnection and reconnection operations are performed simultaneously on the first and second headsets, respectively. This can increase the speed at which the second terminal device reconnects to the headset device and improve the reconnection efficiency. After the disconnection and reconnection operations are completed, the first and second headsets synchronize information, switching the Bluetooth connection target of the second terminal device from the second headset to the first headset. This makes it easier to manage all established Bluetooth connections and ensures data transmission efficiency.

[0107] like Figure 6 As shown, in some embodiments, the above-mentioned Bluetooth connection method may further include the following steps:

[0108] Step 602: When the headset device establishes a Bluetooth connection with M first terminal devices, it is detected that the devices to be connected to the headset device include a third terminal device and a fourth terminal device.

[0109] In an embodiment of the present application, the maximum number N of Bluetooth connections supported by the headset device may be an integer greater than or equal to 2, and M may be an integer greater than or equal to 0 and less than or equal to N-2. The headset device establishing Bluetooth connections with M first terminal devices may include a case where the headset device does not establish a Bluetooth connection with any first terminal device (i.e., M=0), and may also include a case where the number of first terminal devices establishing Bluetooth connections with the headset device is less than or equal to N-2, for example, N is 3, and the headset device only establishes a Bluetooth connection with one first terminal device.

[0110] When the headphone device establishes a Bluetooth connection with M first terminal devices, a scenario may arise where the headphone device needs to establish a Bluetooth connection with two terminal devices simultaneously or continuously. For example, two different terminal devices send Bluetooth connection requests to the headphone device at the same time, or the headphone device needs to reconnect with two different terminal devices. Reconnection means that the headphone device has been paired with the terminal device before and does not need to be paired with the terminal device again but can directly establish a Bluetooth connection with the terminal device.

[0111] Step 604: Establish a Bluetooth connection with the third terminal device through the first headset.

[0112] Step 606: Establish a Bluetooth connection with the fourth terminal device through the second headset.

[0113] In some embodiments, when the headset device establishes Bluetooth connections with M first terminal devices, if it is detected that the devices to be connected to the headset device include a third terminal device and a fourth terminal device, since the number of Bluetooth connections that the headset device can still establish is greater than or equal to 2, Bluetooth connections can be established with the third terminal device and the fourth terminal device respectively. In related technologies, the headset device typically first establishes a Bluetooth connection with one of the terminal devices (such as the third terminal device) and then establishes a Bluetooth connection with another terminal device (such as the fourth terminal device), resulting in a longer connection time and slower speed, which affects the user experience.

[0114] In an embodiment of the present application, if the headphone device detects that the devices to be connected include a third terminal device and a fourth terminal device, a Bluetooth connection can be established with the third terminal device through the first headphone, and a Bluetooth connection can be established with the fourth terminal device through the second headphone in parallel. The first headphone and the second headphone can perform connection operations in parallel, thereby achieving the effect of the headphone device establishing Bluetooth connections with the third terminal device and the fourth terminal device at the same time, reducing the waiting time for connection and improving connection efficiency.

[0115] In some embodiments, when the headphone device establishes a Bluetooth connection with M first terminal devices, if Bluetooth connection requests sent by a third terminal device and a fourth terminal device are received within a first time period, the Bluetooth connection request sent by the third terminal device can be processed by the first headphone, and a Bluetooth connection can be established with the third terminal device, and the Bluetooth connection request sent by the fourth terminal device can be processed by the second headphone, and a Bluetooth connection can be established with the third terminal device.

[0116] The first time period can be set according to actual needs. For example, the first time period can be 1 second, 2 seconds, etc. The first time period can also be set according to the speed at which the headset device establishes a Bluetooth connection. The faster the headset device establishes a Bluetooth connection, the shorter the first time period can be; the slower the headset device establishes a Bluetooth connection, the longer the first time period can be. Furthermore, the first time period can be the length of time it takes for the headset device to normally establish a Bluetooth connection with another terminal device.

[0117] If the headset receives Bluetooth connection requests from the third and fourth devices within the first time period, it is very likely that the headset will receive another Bluetooth connection request before completing one Bluetooth connection request. Therefore, the first headset and the second headset can establish Bluetooth connections with the third and fourth devices respectively, changing the serial connection establishment process to a parallel connection establishment process, thereby reducing the connection waiting time.

[0118] As an embodiment, the third terminal device and / or the fourth terminal device may be a terminal device that has not been paired with the headphone device. The headphone device may enter a pairing state according to a pairing instruction. At this time, the unpaired third terminal device and / or the fourth terminal device may scan the headphone device information, thereby allowing the user to choose to initiate a Bluetooth connection with the headphone device. When the headphone device is in the pairing state, if a Bluetooth connection request is received from the third terminal device and the fourth terminal device within a first time period, a Bluetooth connection may be established between the first headphone and the third terminal device, and a Bluetooth connection may be established between the second headphone and the fourth terminal device.

[0119] Optionally, the manner in which the headphone device enters the pairing state according to the pairing instruction may be similar to the manner in which the headphone device enters the pairing state according to the pairing instruction described in the above embodiment, and details thereof will not be repeated here.

[0120] When the headset device is in the pairing state, an unpaired third terminal device and / or fourth terminal device can scan the headset device and send a scan request to the headset device. If the headset device receives the scan request sent by the third terminal device and the fourth terminal device, it can send a scan response to the third terminal device through the first headset and send a scan response to the fourth terminal device through the second headset. Alternatively, the first headset can directly send a scan response to the third terminal device and the fourth terminal device, or the second headset can send a scan response to the third terminal device and the fourth terminal device.

[0121] If the third and fourth terminal devices are both terminal devices that have not been paired with the headset device, after receiving the scan response, the third and fourth terminal devices may send a Bluetooth connection request to the headset device when determining that a connection with the headset device is required. The first headset may establish a Bluetooth connection with the third terminal device based on the Bluetooth connection request sent by the third terminal device, and the first headset may be paired with the third terminal device during the Bluetooth connection establishment process. The second headset may establish a Bluetooth connection with the fourth terminal device based on the connection request sent by the fourth terminal device, and the second headset may be paired with the fourth terminal device during the Bluetooth connection establishment process.

[0122] In some embodiments, the third terminal device and the fourth terminal device may also be terminal devices that have been connected to the headphone device. The third terminal device and the fourth terminal device may store connection records corresponding to the headphone device, and may directly send a Bluetooth connection request to the headphone device based on the connection records. The headphone device may process the Bluetooth connection request sent by the third terminal device through the first headphone and establish a Bluetooth connection with the third terminal device. During the process of establishing the Bluetooth connection, the first headphone does not need to be paired with the third terminal device; and process the Bluetooth connection request sent by the fourth terminal device through the second headphone and establish a Bluetooth connection with the third terminal device. During the process of establishing the Bluetooth connection, the second headphone does not need to be paired with the fourth terminal device.

[0123] In some embodiments, if the earphone device first receives a Bluetooth connection request sent by a third terminal device, the first earphone (the first earphone can be the main earphone) can process the Bluetooth connection request. When responding to the Bluetooth connection request, the first earphone can send a first message to the second earphone. The first message can be used to notify the second earphone that the first earphone is processing the Bluetooth connection request. After the first earphone completes processing the Bluetooth connection request and successfully establishes a Bluetooth connection with the third terminal device, it can send a second message to the second earphone. The second message is used to notify the second earphone that the first earphone has completed processing the Bluetooth connection request. If the second earphone receives the first message but has not yet received the second message, it means that the first earphone is still in the process of processing the Bluetooth connection request of the third terminal device. If a Bluetooth connection request sent by a fourth terminal device is received during this process, the second earphone can process the Bluetooth connection request sent by the fourth terminal device and establish a Bluetooth connection with the fourth terminal device. The connection speed between the earphone device and the two terminal devices can be improved.

[0124] In some embodiments, the third terminal device and the fourth terminal device may be terminal devices that have been connected to the headphone device. The headphone device may store connection records corresponding to the third terminal device and the fourth terminal device, respectively, and the headphone device may actively reconnect to the third terminal device and the fourth terminal device based on the connection records. When the headphone device is in the reconnection state, a first connection request may be sent to the third terminal device to be reconnected via the first headphone, and a second connection request may be sent to the fourth terminal device to be reconnected via the second headphone. The first connection request is used to reconnect to the third terminal device, and the second connection request is used to reconnect to the fourth terminal device.

[0125] Optionally, the earphone device is placed in the earphone charging box. When the earphone charging box detects the lid opening operation, it can send a lid opening instruction to the earphone device, triggering the earphone device to enter the reconnection state. It should be noted that other methods can also be used to trigger the earphone device to enter the reconnection state. For example, if the earphone device disconnects the Bluetooth connection from all terminal devices, it can trigger the earphone device to enter the reconnection state. The first earphone pages the third terminal device (i.e., sends a Bluetooth connection request) based on previous connection records to establish a first physical link with the third terminal device; the second earphone pages the fourth terminal device (i.e., sends a Bluetooth connection request) based on previous connection records to establish a second physical link with the fourth terminal device; since both parties to the connection have pairing keys, no pairing operation is required during the entire Bluetooth connection process.

[0126] The headset device may store a connection record, which may refer to a record of the headset device's historical connections with other terminal devices. The connection record may include pairing information, device information, etc. corresponding to other terminal devices paired with the headset device.

[0127] The third and fourth terminal devices to be reconnected can be determined based on the connection record. Alternatively, the first two terminal devices ranked in descending order of connection time can be selected as the third and fourth terminal devices. Alternatively, the first two terminal devices ranked in descending order of historical connection frequency can be selected as the third and fourth terminal devices.

[0128] After determining the third terminal device and the fourth terminal device to be reconnected, the first earphone can page the third terminal device. If the third terminal device is within the connection range of the earphone device, it can respond to the page to establish a physical link. Since the third terminal device stores the pairing key of the earphone device, there is no need to perform pairing operations, and a Bluetooth connection can be established with the first earphone. Similarly, the second earphone can page the fourth terminal device. If the fourth terminal device is within the connection range of the earphone device, it can respond to the page. Since the fourth terminal device stores the pairing key of the earphone device, there is no need to perform pairing operations, and a Bluetooth connection can be established with the second earphone. The first earphone and the second earphone can reconnect with different terminal devices in parallel, which can improve the reconnection efficiency.

[0129] In some embodiments, when the headset device is in the reconnecting state, the headset device may also enable page scan mode, or enable page scan mode and inquiry scan mode (i.e., it is in pairing state). In the case where the terminal device to be reconnected only includes a third terminal device, a first connection request may be sent to the third terminal device via the first headset to establish a Bluetooth connection with the third terminal device. If a Bluetooth connection request is received from a fourth terminal device within the second time period after the first headset sends the first connection request, the Bluetooth connection request may be processed by the second headset, and a Bluetooth connection may be established with the fourth terminal device.

[0130] The second time period can be set based on actual needs, such as 1 second, 2 seconds, etc. The second time period can also be set based on the speed at which the headset device reconnects. The faster the headset device reconnects, the shorter the second time period can be, and the slower the headset device reconnects, the longer the second time period can be. While the headset device is reconnecting to the third terminal device, it can also respond to the Bluetooth connection request sent by the fourth terminal device, without having to wait for the reconnection to succeed before responding. This allows the Bluetooth connection to be established with the two terminal devices more quickly, improving connection efficiency.

[0131] That is, the headset device can process in parallel a Bluetooth backconnection initiated by the headset device with the terminal device and a Bluetooth connection initiated by another terminal device with the headset device.

[0132] In some embodiments, after the first headset establishes a Bluetooth connection with the third terminal device, the connection information of the first terminal device can be synchronized to the second headset via the first headset. After the second headset establishes a Bluetooth connection with the fourth terminal device, the connection information of the fourth terminal device can be synchronized to the first headset via the second headset.

[0133] Optionally, the first headset can be the master headset and the second headset can be the slave headset. After the second headset synchronizes the connection information corresponding to the fourth terminal device to the first headset, the Bluetooth connection object of the fourth terminal device is switched from the second headset to the first headset, and the second headset monitors the Bluetooth connection between the first headset and the fourth terminal device. Alternatively, the first headset can synchronize data transmitted between the first headset and the fourth terminal device to the second headset, thereby achieving master-slave synchronization.

[0134] After the first headset establishes a Bluetooth connection with a third terminal device, the first headset can also synchronize the connection information corresponding to the third terminal device with the second headset, so that the second headset can monitor the Bluetooth connection between the first headset and the third terminal device based on the connection information. For all terminal devices connected to the headset, data transmission is managed in a manner that the first headset connects and the second headset monitors or receives data forwarded by the first headset, which makes management more convenient and improves data transmission efficiency.

[0135] Figure 7A FIG. 1 is an interactive sequence diagram of connecting a headset device to two terminal devices in one embodiment. Figure 7A As shown, the earphone device can be a device that supports Bluetooth "one-to-two", and terminal device A and terminal device B are both devices that have been paired with the earphone device. When the earphone device has not established a Bluetooth connection with other terminal devices, when the earphone device is in pagescan mode, it receives Bluetooth connection requests sent by terminal device A and terminal device B within a first time period. The first earphone can process the Bluetooth connection request sent by terminal device A and establish a Bluetooth connection with terminal device A, and the second earphone can process the Bluetooth connection request sent by terminal device B and establish a Bluetooth connection with terminal device B. After the first earphone successfully establishes a Bluetooth connection with terminal device A, the connection information of terminal device A can be synchronized with the second earphone. After the second earphone successfully establishes a Bluetooth connection with terminal device B, the connection information of terminal device B can be synchronized with the second earphone, realizing information synchronization and switching the Bluetooth connection object of terminal device B from the second earphone to the first earphone.

[0136] Figure 7B This is an interactive sequence diagram of another embodiment in which a headset device is connected to two terminal devices. Figure 7B As shown, the headphone device can be a device that supports Bluetooth "one to two", and both terminal device A and terminal device B are devices that have not been paired with the headphone device. When the headphone device has not established a Bluetooth connection with other terminal devices, when the headphone device is in pagescan mode and page scan mode (pairing state), terminal device A and terminal device B can scan the headphone device and send a Bluetooth connection request to the headphone device. The headphone device receives the Bluetooth connection request sent by terminal device A and terminal device B within a first time period. The first headphone can process the Bluetooth connection request sent by terminal device A and establish a Bluetooth connection with terminal device A. The second headphone can process the Bluetooth connection request sent by terminal device B and establish a Bluetooth connection with terminal device B. After the first headphone successfully establishes a Bluetooth connection with terminal device A, the connection information of terminal device A can be synchronized with the second headphone. After the second headphone successfully establishes a Bluetooth connection with terminal device B, the connection information of terminal device B can be synchronized with the second headphone to achieve information synchronization, so that the Bluetooth connection object of terminal device B is switched from the second headphone to the first headphone.

[0137] Figure 7C FIG. 1 is an interactive sequence diagram of connecting a headset device to two terminal devices in another embodiment. Figure 7CAs shown, the earphone device can be a device that supports Bluetooth "one to two", and both terminal device A and terminal device B are devices that have been paired with the earphone device. The earphone device can enter the reconnection state without establishing a Bluetooth connection with other terminal devices. If terminal device A and terminal device B are both in page scan mode, the first earphone can send a first connection request to terminal device A according to the stored connection record of terminal device A, and reconnect with terminal device A based on the first connection request. The second earphone can send a second connection request to terminal device B according to the stored connection record of terminal device B, and reconnect with terminal device B based on the second connection request. After the first earphone successfully establishes a Bluetooth connection with terminal device A, the connection information of terminal device A can be synchronized with the second earphone. After the second earphone successfully establishes a Bluetooth connection with terminal device B, the connection information of terminal device B can be synchronized with the second earphone to achieve information synchronization, so that the Bluetooth connection object of terminal device B is switched from the second earphone to the first earphone.

[0138] It should be noted that Figures 7A to 7C It is only used to illustrate the implementation process of the embodiment of the present application and is not used to limit the specific headphone device, terminal device and connection scenario.

[0139] In some embodiments, when the headset device establishes a Bluetooth connection with M first terminal devices, if the device to be connected to the headset device only includes a third terminal device (for example, the headset device only receives a Bluetooth connection request sent by the third terminal device, or only needs to connect back to the third terminal device, and does not receive Bluetooth connection requests sent by the third terminal device and the fourth terminal device within the first time period, etc.), that is, the headset device only needs to establish a Bluetooth connection with one other terminal device, then the headset device can establish a Bluetooth connection with the third terminal device through the first headset or the second headset. For the first terminal device in the "headphone device establishes Bluetooth connections with N first terminal devices respectively" described in each of the above embodiments, the Bluetooth connection can be established using the method described in steps 602 to 606.

[0140] When the number of first terminal devices that have established a Bluetooth connection with the headphone device reaches N-1, if the devices to be connected to the headphone device only include the third terminal device, the headphone device can establish a Bluetooth connection with the third terminal device through the first headphone or the second headphone. If the devices to be connected to the headphone device include the third terminal device and the fourth terminal device, if the headphone device wants to establish a Bluetooth connection with the third terminal device and the fourth terminal device, it is also necessary to disconnect the Bluetooth connection of one of the first terminal devices. Therefore, a Bluetooth connection can be established with the third terminal device through the first headphone or the second headphone first, and then a Bluetooth connection can be established with the fourth terminal device through the second headphone while the first headphone performs the disconnection process. Optionally, the target terminal device for the first headphone to perform the disconnection process can be determined from the first terminal device other than the third terminal device that has established a Bluetooth connection with the headphone device.

[0141] When the headphone device establishes Bluetooth connections with N first terminal devices respectively, if the devices to be connected to the headphone device include a third terminal device and a fourth terminal device, the third terminal device and the fourth terminal device can serve as the second terminal devices in the above embodiments, and the headphone device performs disconnection processing and Bluetooth connection in parallel to successfully establish Bluetooth connections with the third terminal device and the fourth terminal device.

[0142] Optionally, the Bluetooth connection in the embodiments of the present application may include any one of a classic Bluetooth connection and a Bluetooth Low Energy (BLE) connection. In a BLE connection scenario, the headset device may send a BLE broadcast, and other terminal devices may scan and obtain the BLE broadcast and establish a BLE Bluetooth connection with the headset device. It should be noted that other connection methods may also be applicable and may change with the development of the Bluetooth protocol.

[0143] It should be noted that the terminal device that has not been paired with the headphone device involved in the embodiments of the present application refers to the terminal device in which no connection information corresponding to the headphone device is stored; the terminal device that has been paired with the headphone device involved in the embodiments of the present application refers to the terminal device in which the connection information corresponding to the headphone device is stored.
