Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a method, apparatus and system for fast switching of Bluetooth connections between multiple devices. Background Technology

[0002] Bluetooth communication is a short-range wireless technology for data transmission between devices. Due to its low cost, low power consumption, ease of deployment, and ability to quickly interconnect devices, it is widely used in consumer electronics, the Internet of Things (IoT), and medical fields. In the classic Bluetooth protocol, audio transmission relies on the A2DP (Advanced Audio Distribution Profile) protocol. Traditional Bluetooth pairing requires the user to manually put the Bluetooth audio source device (such as a Bluetooth-enabled mobile phone or computer, conference room speakers, fitness equipment, exhibition equipment, etc.) into pairing mode (e.g., enable "discoverable"), and then the Bluetooth playback device (such as Bluetooth headphones) searches for and connects.

[0003] This traditional Bluetooth pairing mechanism works in one-to-one scenarios, but it presents several problems when there are multiple audio source devices in public places (such as conference rooms, gyms, and exhibition halls). The problems include: cumbersome operation: users need to set each audio source device to pairing mode individually and manually connect the headphones, which is inefficient; signal interference risk: when multiple audio source devices are in pairing mode simultaneously, it can easily lead to misconnections or signal interference; and privacy risks: audio source devices publicly broadcast pairing information, which may be scanned and connected to by unauthorized devices. Summary of the Invention

[0007] Furthermore, this invention also proposes a method for fast switching of Bluetooth connections between multiple devices, the method comprising: The Bluetooth playback device provides Bluetooth auxiliary connection devices with Bluetooth pairing information in advance. In a scenario with multiple audio source devices, in response to a user's Bluetooth connection operation, the Bluetooth playback device establishes a Bluetooth connection with a target audio source device among the multiple audio source devices that have obtained Bluetooth pairing information from the Bluetooth auxiliary connection device that has completed pairing.

[0008] Furthermore, the present invention also proposes a multi-device Bluetooth connection fast switching device, configured in a Bluetooth playback device, the device comprising: The second pre-pairing module is used by the Bluetooth playback device to pre-provide Bluetooth auxiliary connection device with Bluetooth pairing information; The first Bluetooth connection module is used to, in a scenario with multiple audio source devices, respond to a user's Bluetooth connection operation, establish a Bluetooth connection between the Bluetooth playback device and a target audio source device among the multiple audio source devices that have obtained Bluetooth pairing information from the Bluetooth auxiliary connection device that has completed pairing.

[0009] Furthermore, this invention also proposes a method for fast switching of Bluetooth connections between multiple devices, the method comprising: In a scenario with multiple audio source devices, in response to the user's Bluetooth connection operation, the target audio source device among the multiple audio source devices obtains the Bluetooth pairing information that the Bluetooth auxiliary connection device has previously obtained from the Bluetooth playback device from the Bluetooth auxiliary connection device. The target audio source device establishes a Bluetooth connection with the Bluetooth playback device based on the obtained Bluetooth pairing information.

[0010] Furthermore, this invention also proposes a multi-device Bluetooth connection fast switching device, configured in an audio source device, the device comprising: The second auxiliary connection module is used to, in a scenario with multiple audio source devices, respond to the user's Bluetooth connection operation, and the target audio source device among the multiple audio source devices obtains the Bluetooth pairing information that the Bluetooth auxiliary connection device has previously obtained from the Bluetooth playback device from the Bluetooth auxiliary connection device. The second Bluetooth connection module is used for the target audio source device to establish a Bluetooth connection with the Bluetooth playback device based on the obtained Bluetooth pairing information.

[0015] The beneficial effects of the technical solution provided by this invention include: In scenarios with multiple audio source devices, a Bluetooth auxiliary connection device can be pre-binded to a Bluetooth playback device, enabling the Bluetooth auxiliary connection device to obtain the Bluetooth pairing information of the Bluetooth playback device. When it is necessary to connect the Bluetooth playback device to one of the multiple audio source devices (i.e., the target audio source device) via Bluetooth, the target audio source device can obtain the Bluetooth pairing information obtained by the Bluetooth auxiliary connection device from the Bluetooth playback device, thereby enabling the Bluetooth connection between the Bluetooth playback device and the target audio source device through the Bluetooth auxiliary connection device.

[0016] In this way, when a user needs to connect a Bluetooth playback device to one of multiple audio source devices, or switch from one audio source device to another, they only need to connect the Bluetooth auxiliary connection device, which obtains Bluetooth pairing information from the Bluetooth playback device, to the audio source device (i.e., the target audio source device). This allows the Bluetooth playback device to connect to any of the multiple audio source devices, enabling quick connection and switching. Furthermore, when connecting the audio source device to the Bluetooth playback device, the audio source device automatically obtains the Bluetooth pairing information from the playback device, achieving automatic one-to-one pairing without any additional user intervention. This is simple, efficient, and eliminates signal interference issues. Moreover, during the Bluetooth connection process, there is no need to publicly broadcast pairing information, reducing the security risk of information leakage and protecting privacy.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In daily work and life, we often use Bluetooth audio devices (such as Bluetooth headphones and Bluetooth-enabled mobile phones, computers, speakers, monitors, etc.) to play and listen to audio information. During use, Bluetooth audio devices often need to be paired one-to-one to establish a Bluetooth connection for audio transmission. Furthermore, typically, one of the two Bluetooth audio devices is a source device providing the audio information, and the other is a Bluetooth playback device (or Bluetooth receiver) for playing and listening to the audio.

[0021] In traditional technologies, the traditional one-to-one Bluetooth connection pairing mechanism is feasible in scenarios with only two Bluetooth audio devices; however, in public places (such as conference rooms, gyms, exhibition halls, etc.) with multiple audio source devices, the traditional one-to-one Bluetooth connection pairing mechanism will have some problems.

[0022] For example, users need to set multiple audio source devices to pairing mode one by one and manually connect Bluetooth playback devices (such as Bluetooth headphones), which is cumbersome and inefficient. Moreover, when multiple audio source devices are in pairing mode at the same time, it is easy for Bluetooth playback devices (such as Bluetooth headphones) to connect incorrectly or cause signal interference. Furthermore, the audio source devices publicly broadcast pairing information, which may be scanned and connected by unauthorized Bluetooth playback devices, posing a risk of privacy leakage.

[0023] Therefore, this invention proposes a method, apparatus, and system for fast switching of Bluetooth connections between multiple devices, which solves the problems of cumbersome operation, signal interference risk, and privacy leakage risks in the traditional Bluetooth connection pairing mechanism when there are multiple audio source devices at the same time. It can realize fast and automatic pairing and switching of Bluetooth playback devices (such as Bluetooth headphones) in the environment of multiple audio source devices.

[0024] Example 1 This invention proposes a method for fast switching of Bluetooth connections between multiple devices. Specifically, as follows: Figure 1 As shown, the method for quickly switching between multiple device Bluetooth connections may include the following steps: S12, The Bluetooth auxiliary connection device obtains the Bluetooth pairing information of the Bluetooth playback device in advance; S14. In scenarios with multiple audio source devices, in response to the user's Bluetooth connection operation, the Bluetooth auxiliary connection device that completes pairing is used to enable the target audio source device among the multiple audio source devices to obtain Bluetooth pairing information, and enables the target audio source device to establish a Bluetooth connection with the Bluetooth playback device based on the Bluetooth pairing information.

[0025] like Figures 2 to 3 As shown, in scenarios with multiple audio source devices, a Bluetooth auxiliary connection device can be pre-paired with a Bluetooth playback device, allowing the auxiliary connection device to obtain the Bluetooth pairing information of the playback device. When it is necessary to establish a Bluetooth connection between the playback device and one of the multiple audio source devices (i.e., the target audio source device), the target audio source device can obtain the Bluetooth pairing information obtained by the auxiliary connection device from the playback device, thereby enabling the Bluetooth connection between the playback device and the target audio source device. The auxiliary connection device obtaining the Bluetooth pairing information of the playback device means that the auxiliary connection device first pairs with the playback device, then saves the pairing information, and then the target audio source device copies the Bluetooth pairing information saved in the auxiliary connection device.

[0026] Thus, as Figures 3 to 4 As shown, when a user needs to connect a Bluetooth playback device to one of multiple audio source devices via Bluetooth, or switch from one audio source device to another, they only need to connect the Bluetooth auxiliary connection device, which obtains Bluetooth pairing information from the Bluetooth playback device, to the audio source device (i.e., the target audio source device). This allows the Bluetooth playback device to connect to any of the multiple audio source devices, enabling quick connection and switching. Furthermore, when connecting the audio source device to the Bluetooth playback device, the audio source device automatically obtains the Bluetooth pairing information from the playback device, achieving automatic one-to-one pairing without any additional user intervention. This is simple, efficient, and eliminates signal interference issues. Moreover, during the Bluetooth connection process, there is no need to publicly broadcast pairing information, reducing the security risk of information leakage and protecting privacy.

[0027] Furthermore, in step S12, the Bluetooth auxiliary connection device pre-acquires the Bluetooth pairing information of the Bluetooth playback device, which may further include the following steps: S122. In response to the user's Bluetooth pre-pairing operation, when the first real-time distance between the Bluetooth auxiliary connection device and the Bluetooth playback device reaches the first preset distance, the Bluetooth auxiliary connection device and the Bluetooth playback device enter the pairing state.

[0028] In this embodiment, the user's Bluetooth pre-pairing operation can refer to the user bringing the Bluetooth auxiliary connection device close to or attaching it to the Bluetooth playback device, so that the Bluetooth auxiliary connection device reaches the pairing distance requirement (i.e., the first preset distance) with the Bluetooth playback device, thereby enabling the Bluetooth auxiliary connection device to pair with the Bluetooth playback device. This avoids mis-pairing of the Bluetooth auxiliary connection device with other Bluetooth devices. Furthermore, in this embodiment, the first preset distance can refer to the Bluetooth auxiliary connection device being in contact with the Bluetooth playback device, i.e., zero distance; alternatively, the first preset distance can also refer to the distance between the Bluetooth auxiliary connection device and the Bluetooth playback device being within a pre-set pairing distance range. Moreover, the first preset distance can typically be represented by signal strength; that is, the distance with the signal strength required for the Bluetooth auxiliary connection device and the Bluetooth playback device to connect and pair can be set as the first preset distance.

[0029] Furthermore, pairing between the Bluetooth auxiliary connection device and the Bluetooth playback device can be performed using a third-party device or directly between the two. In this embodiment, the Bluetooth auxiliary connection device can be attached to the Bluetooth playback device, and the Bluetooth auxiliary connection device can filter signal strength to ensure that it only enters pairing mode with the attached Bluetooth playback device.

[0030] S124. The Bluetooth auxiliary connection device exchanges pairing information with the Bluetooth playback device, obtains the Bluetooth pairing information of the Bluetooth playback device, and establishes a unique binding relationship between the two; the Bluetooth pairing information includes device identification information and encryption key.

[0031] Once the Bluetooth auxiliary connection device and the Bluetooth playback device enter pairing mode, the Bluetooth auxiliary connection device can obtain the Bluetooth pairing information of the playback device, namely the first device identification information and the first encryption key of the playback device. Similarly, the Bluetooth auxiliary connection device can also provide the Bluetooth playback device with its Bluetooth pairing information, namely the second device identification information and the second encryption key of the Bluetooth auxiliary connection device, to achieve the binding between the two. Moreover, the binding between the Bluetooth auxiliary connection device and the Bluetooth playback device only requires one operation, and no repeated operations are needed subsequently.

[0032] Furthermore, in step S124, the Bluetooth auxiliary connection device and the Bluetooth playback device exchange pairing information, which may further include the following steps: S1242, The Bluetooth auxiliary connection device sends a connection request message to the Bluetooth playback device; S1244. After the Bluetooth playback device responds to the connection request information, it enters the pairing process; S1246. When the Bluetooth playback device and the Bluetooth auxiliary connection device enter the pairing process, they exchange pairing parameters, generate and save a long-term key, and establish an encrypted connection.

[0033] In this embodiment, the Bluetooth auxiliary connection device can communicate with the Bluetooth playback device via Bluetooth, enabling the Bluetooth auxiliary connection device to exchange pairing information with the Bluetooth playback device through Bluetooth communication. In this case, the Bluetooth auxiliary connection device can be a Bluetooth Low Energy tag, or a card, wearable device (such as a bracelet, watch, etc.) with a Bluetooth Low Energy tag.

[0034] Furthermore, the Bluetooth auxiliary connection device can communicate with the Bluetooth playback device via NFC, enabling the Bluetooth auxiliary connection device to exchange pairing information with the Bluetooth playback device through NFC communication. In this case, the Bluetooth auxiliary connection device can be an NFC card, or a wearable device with NFC functionality (such as a bracelet, watch, etc.).

[0035] Furthermore, in step S14, in response to the user's Bluetooth connection operation, the completed Bluetooth auxiliary connection device is used to enable the target audio source device among multiple audio source devices to obtain Bluetooth pairing information, which may further include the following steps: S142. In response to the user's Bluetooth connection operation, when the second real-time distance between the Bluetooth auxiliary connection device and the target audio source device reaches the second preset distance, the Bluetooth auxiliary connection device and the target audio source device enter the connection state.

[0036] In this embodiment, the user's Bluetooth connection operation can refer to the user bringing the Bluetooth auxiliary connection device close to or attaching it to the target audio source device, so that the Bluetooth auxiliary connection device reaches the pairing distance requirement (i.e., the second preset distance) with the target audio source device, thereby enabling the Bluetooth auxiliary connection device to pair with the target audio source device. This avoids accidental pairing of the Bluetooth auxiliary connection device with other Bluetooth devices. Similarly, in this embodiment, the second preset distance can refer to the Bluetooth auxiliary connection device being in contact with the target audio source device, i.e., zero distance; or it can refer to the distance between the Bluetooth auxiliary connection device and the target audio source device being within a pre-set pairing distance range. Similarly, the second preset distance can also be represented by signal strength (such as the strength of near-field communication signals, Bluetooth RSSI signals, etc.), that is, the distance with the signal strength required for the Bluetooth auxiliary connection device to connect and pair with the target audio source device is set as the second preset distance.

[0037] Similarly, pairing the Bluetooth auxiliary connection device with the target audio source device can be done using a third-party device or directly between the two. In this embodiment, the Bluetooth auxiliary connection device can be directly attached to the target audio source device, and the Bluetooth auxiliary connection device can filter signal strength to ensure that it only enters pairing mode with the attached target audio source device.

[0038] S144. When the Bluetooth auxiliary connection device is connected to the target audio source device, the Bluetooth auxiliary connection device is used to allow the target audio source device to read and copy the Bluetooth pairing information obtained by the Bluetooth auxiliary connection device.

[0039] After the Bluetooth auxiliary connection device and the target audio source device enter pairing mode, the target audio source device can obtain the first device identification information and the first encryption key obtained by the Bluetooth auxiliary connection device from the Bluetooth playback device. Simultaneously, the target audio source device can also obtain its own Bluetooth pairing information from the Bluetooth auxiliary connection device, namely the second device identification information and the second encryption key of the Bluetooth auxiliary connection device. This allows the target audio source device to read and copy the Bluetooth pairing information obtained by the Bluetooth auxiliary connection device, as well as its own Bluetooth pairing information, thereby enabling the target audio source device to replicate the identity of the Bluetooth auxiliary connection device and establish a connection and pairing with the Bluetooth playback device.

[0040] Furthermore, in step S142, the Bluetooth assisted connection device and the target audio source device enter a connection state, which may further include the following steps: S1422, the Bluetooth auxiliary connection device and the target audio source device enter the connection state via near field communication.

[0041] In other words, the Bluetooth auxiliary connection device and the target audio source device obtain corresponding Bluetooth pairing information via NFC, enabling a Bluetooth connection between them. For example, the Bluetooth auxiliary connection device can be an NFC card, or a wearable device with NFC functionality (such as a bracelet or watch). The NFC-enabled Bluetooth auxiliary connection device can be brought close to the target audio source device, allowing the target audio source device to read the Bluetooth pairing information from the Bluetooth auxiliary connection device, thereby obtaining the Bluetooth pairing information of the Bluetooth playback device (i.e., the first device identification information and the first encryption key).

[0042] Alternatively, S1424, the Bluetooth auxiliary connection device is used to allow the target audio source device to be detected via Bluetooth RSSI, so that the target audio source device and the Bluetooth auxiliary connection device can enter a connection state.

[0043] Specifically, the Bluetooth auxiliary connection device can broadcast a Bluetooth signal with a specific identifier and move closer to the target audio source device. The target audio source device can detect the proximity of the Bluetooth auxiliary connection device through Bluetooth RSSI (signal strength index) and automatically send an information request to the Bluetooth auxiliary connection device to obtain Bluetooth pairing information, thereby achieving connection between the target audio source device and the Bluetooth auxiliary connection device.

[0044] Alternatively, S1426, the Bluetooth auxiliary connection device is used to enable the target audio source device to virtualize itself as the Bluetooth auxiliary connection device, so that the target audio source device and the Bluetooth auxiliary connection device can enter a connection state.

[0045] In other words, the target audio source device can obtain the Bluetooth pairing information of the Bluetooth auxiliary connection device and virtualize itself as the Bluetooth auxiliary connection device (i.e., a paired device simulating a Bluetooth playback device). This can bypass the traditional Bluetooth pairing process and also enable the connection between the target audio source device and the Bluetooth auxiliary connection device.

[0046] Furthermore, in step S14, the process of establishing a Bluetooth connection between the target audio source device and the Bluetooth playback device based on Bluetooth pairing information may further include the following steps: S146. The Bluetooth auxiliary connection device is used to allow the target audio source device to copy the Bluetooth connection identity of the Bluetooth auxiliary connection device based on the copied Bluetooth pairing information.

[0047] After the target audio source device reads and copies the Bluetooth pairing information obtained by the Bluetooth auxiliary connection device, as well as its own Bluetooth pairing information, the target audio source device can copy the Bluetooth connection identity of the Bluetooth auxiliary connection device, thus simulating the target audio source device as a Bluetooth auxiliary connection device that has been paired with the Bluetooth playback device.

[0048] S148. Enables the target audio source device to directly establish an A2DP (Advanced Audio Distribution Profile) audio connection with the Bluetooth playback device based on the copied Bluetooth connection identity.

[0049] When the target audio source device is simulated as a Bluetooth auxiliary connection device that has been paired with the Bluetooth playback device, the target audio source device can directly establish an A2DP audio connection with the Bluetooth playback device, and can directly transmit the audio information of the target audio source device to the Bluetooth playback device, so that the Bluetooth playback device can play the A2DP audio information of the target audio source device.

[0050] Furthermore, in step S148, enabling the target audio source device to directly establish an A2DP audio connection with the Bluetooth playback device based on the copied Bluetooth connection identity may further include the following steps: S1482. Enables the target audio source device to verify pairing information with the Bluetooth playback device based on the copied Bluetooth connection identity.

[0051] After the target audio source device and the Bluetooth playback device establish a connection, the pairing information is verified. This is based on the key system (i.e., encryption key) negotiated and stored during the initial pairing (i.e. when the Bluetooth playback device and the Bluetooth auxiliary connection device are paired via Bluetooth). Through identity authentication, encryption verification and other mechanisms, it is confirmed that both parties are legitimate devices that have been paired before, thus preventing unauthorized devices from accessing the device or data from being tampered with.

[0052] S1484. When the encryption key of the target audio source device is detected to be consistent with the encryption key of the Bluetooth auxiliary connection device, the target audio source device establishes an A2DP audio connection with the Bluetooth playback device.

[0053] In the preceding steps, the Bluetooth playback device has already paired with the Bluetooth auxiliary connection device. Subsequently, the target audio source device copies the Bluetooth pairing information from the pairing process between the Bluetooth auxiliary connection device and the Bluetooth playback device, thus simulating a Bluetooth auxiliary connection device already paired with the Bluetooth playback device. This allows the target audio source device to possess the encryption key of the Bluetooth auxiliary connection device. Therefore, verifying the pairing information between the target audio source device and the Bluetooth playback device is equivalent to verifying the pairing information between the Bluetooth auxiliary connection device and the Bluetooth playback device. Verification is successful when the encryption key of the target audio source device matches the encryption key of the Bluetooth auxiliary connection device. Once the pairing information verification between the target audio source device and the Bluetooth playback device is successful, an A2DP audio connection can be established, allowing the Bluetooth playback device to play A2DP audio information from the target audio source device.

[0054] Moreover, such as Figure 5 As shown, in step S14, after the target audio source device establishes a Bluetooth connection with the Bluetooth playback device based on the Bluetooth pairing information, the following steps may also be included: S16, The Bluetooth auxiliary connection device is used to enable the target audio source device to detect the third real-time distance between the Bluetooth auxiliary connection device and the target audio source device in real time.

[0055] When the target audio source device connects and pairs with the Bluetooth playback device through the Bluetooth auxiliary connection device, it will also detect the third real-time distance between the Bluetooth auxiliary connection device and the target audio source device. Specifically, the third real-time distance between the Bluetooth auxiliary connection device and the target audio source device can be detected by signal strength.

[0056] S18. When the third real-time distance reaches the third preset distance, the Bluetooth auxiliary connection device disconnects from the target audio source device, causing the target audio source device to disconnect from the Bluetooth playback device.

[0057] In this embodiment, the signal strength when the Bluetooth auxiliary connection device and the target audio source device disconnect from pairing can be set to the signal strength when they reach a third preset distance. When the third real-time distance between the Bluetooth auxiliary connection device and the target audio source device reaches the third preset distance, it is determined that the connection signal strength between the Bluetooth auxiliary connection device and the target audio source device is insufficient to achieve pairing, and at this time, they disconnect from pairing (i.e., the connection is cut off). When the connection between the Bluetooth auxiliary connection device and the target audio source device is cut off, the target audio source device can no longer simulate the Bluetooth connection identity of the Bluetooth auxiliary connection device, causing the connection between the target audio source device and the Bluetooth playback device to be cut off accordingly.

[0058] Furthermore, after the Bluetooth auxiliary connection device disconnects from the target audio source device in step S18, the following steps may also be included: S19. In a scenario with multiple audio source devices, in response to the user's Bluetooth connection operation, the Bluetooth auxiliary connection device that completes pairing is used to enable the second target audio source device among the multiple audio source devices to obtain Bluetooth pairing information, and enables the second target audio source device to establish a Bluetooth connection with the Bluetooth playback device based on the Bluetooth pairing information.

[0059] In essence, after disconnecting from one target audio source device among multiple audio source devices, the Bluetooth auxiliary connection device can establish a Bluetooth connection with another target audio source device (i.e., the second target audio source device). This allows the second target audio source device to simulate the Bluetooth connection identity of the auxiliary connection device, establishing a Bluetooth connection and an A2DP audio connection with the Bluetooth playback device. Consequently, the Bluetooth playback device can receive A2DP audio information sent by the second target audio source device. Thus, through a Bluetooth auxiliary connection device pre-paired with the Bluetooth playback device, any one of the multiple audio source devices can establish a Bluetooth connection and an A2DP audio connection with the Bluetooth playback device, and switching between them can be performed at any time.

[0060] Furthermore, the specific method by which the Bluetooth auxiliary connection device connects to the second target audio source device to achieve the connection between the Bluetooth playback device and the second target audio source device is similar to the specific method by which the Bluetooth auxiliary connection device connects to the target audio source device to achieve the connection between the Bluetooth playback device and the target audio source device, and will not be repeated here.

[0061] The multi-device Bluetooth connection fast switching solution proposed in this invention allows audio source devices to obtain the identity information of Bluetooth playback devices through a Bluetooth auxiliary connection device in scenarios with multiple audio source devices, without having to publicly broadcast their own pairing status, thus improving security. Users only need to touch or approach the target audio source device among multiple audio source devices to trigger a fully automatic connection process. It supports seamless switching of the same Bluetooth playback device between different audio source devices and is suitable for complex multi-device environments.

[0062] Furthermore, the present invention also proposes a multi-device Bluetooth connection fast switching device 100, configured in the Bluetooth auxiliary connection device 10. For example... Figure 6 As shown, the multi-device Bluetooth connection quick switching device 100 may include: The first pre-pairing module 102 is used for the Bluetooth auxiliary connection device to obtain the Bluetooth pairing information of the Bluetooth playback device in advance. The first auxiliary connection module 104 is used in a scenario with multiple audio source devices to respond to the user's Bluetooth connection operation and complete the pairing of the Bluetooth auxiliary connection device. This device is used to enable the target audio source device among the multiple audio source devices to obtain Bluetooth pairing information and to enable the target audio source device to establish a Bluetooth connection with the Bluetooth playback device based on the Bluetooth pairing information.

[0063] In addition, such as Figure 7 As shown, the multi-device Bluetooth connection fast switching device 100 may further include a first switching connection module 106, which can be used for: The Bluetooth auxiliary connection device is used to enable the target audio source device to detect the third real-time distance between the Bluetooth auxiliary connection device and the target audio source device in real time. When the third real-time distance reaches the third preset distance, the Bluetooth auxiliary connection device disconnects from the target audio source device, causing the target audio source device to disconnect from the Bluetooth playback device.

[0064] Furthermore, the first switching connection module 106 can also be used in a scenario with multiple audio source devices to respond to the user's Bluetooth connection operation and complete the pairing of the Bluetooth auxiliary connection device for the second target audio source device among the multiple audio source devices to obtain Bluetooth pairing information, and enable the second target audio source device to establish a Bluetooth connection with the Bluetooth playback device according to the Bluetooth pairing information.

[0065] The multi-device Bluetooth connection fast switching device 100 described in this embodiment corresponds to the multi-device Bluetooth connection fast switching method described above. The functions of each module in the multi-device Bluetooth connection fast switching device 100 in this embodiment are described in detail in the corresponding method embodiments, and will not be repeated here.

[0066] In addition, such as Figure 8 As shown, the present invention also proposes a Bluetooth assisted connection device 10, which may include: The first storage unit 11 is used to store computer programs; The first wireless signal transceiver unit 13 is used to receive or transmit radio signals; The first processor 15 is used to execute the computer program, enabling the Bluetooth assisted connection device to implement the multi-device Bluetooth connection fast switching method as described above.

Specifically, as follows: Figure 9 As shown, the method for quickly switching between multiple device Bluetooth connections may include the following steps: S22, The Bluetooth playback device provides Bluetooth auxiliary connection devices with Bluetooth pairing information in advance; S24. In a scenario with multiple audio source devices, in response to the user's Bluetooth connection operation, the Bluetooth playback device establishes a Bluetooth connection with the target audio source device among the multiple audio source devices that have obtained Bluetooth pairing information from the paired Bluetooth auxiliary connection device.

[0070] In scenarios with multiple audio source devices, the Bluetooth auxiliary connection device can obtain the Bluetooth pairing information of the Bluetooth playback device, allowing the Bluetooth playback device to be pre-bound to the Bluetooth auxiliary connection device. When it is necessary to connect the Bluetooth playback device to one of the multiple audio source devices (i.e., the target audio source device) via Bluetooth, the target audio source device can obtain the Bluetooth pairing information obtained by the Bluetooth auxiliary connection device from the Bluetooth playback device, thereby enabling the Bluetooth connection between the Bluetooth playback device and the target audio source device through the Bluetooth auxiliary connection device.

[0071] In this context, "the Bluetooth playback device provides Bluetooth auxiliary connection device with Bluetooth pairing information in advance" means that the Bluetooth auxiliary connection device first pairs with the Bluetooth playback device, then saves the Bluetooth pairing information, and then the target audio source device copies the Bluetooth pairing information saved in the Bluetooth auxiliary connection device.

[0072] When a user needs to connect a Bluetooth playback device to one of multiple audio source devices via Bluetooth, or switch between multiple audio source devices, they only need to connect a Bluetooth auxiliary connection device that obtains Bluetooth pairing information from the Bluetooth playback device to the audio source device (i.e., the target audio source device). This allows the Bluetooth playback device to connect to any of the multiple audio source devices, enabling quick connection and switching. Furthermore, when connecting an audio source device to a Bluetooth playback device, the audio source device automatically obtains the Bluetooth pairing information from the playback device, achieving automatic one-to-one pairing without any additional user intervention. This is simple, efficient, and eliminates signal interference issues. Moreover, during the Bluetooth connection process, there is no need to publicly broadcast pairing information, reducing the security risk of information leakage and protecting privacy.

[0073] Furthermore, in step S22, the Bluetooth playback device provides Bluetooth auxiliary connection device with Bluetooth pairing information in advance, which may further include the following steps: S222. In response to the user's Bluetooth pre-pairing operation, when the first real-time distance between the Bluetooth auxiliary connection device and the Bluetooth playback device reaches the first preset distance, the Bluetooth playback device and the Bluetooth auxiliary connection device enter the pairing state. S224. The Bluetooth playback device and the Bluetooth auxiliary connection device exchange pairing information, which is used for the Bluetooth auxiliary connection device to obtain the Bluetooth pairing information of the Bluetooth playback device, so that the two establish a unique binding relationship; the Bluetooth pairing information includes device identification information and encryption key.

When the Bluetooth playback device receives the connection request information, it enters the pairing process; S2246. When the Bluetooth playback device and the Bluetooth auxiliary connection device enter the pairing process, they exchange pairing parameters, generate and save a long-term key, and establish an encrypted connection.

[0076] Furthermore, in step S24, in response to the user's Bluetooth connection operation, the Bluetooth playback device establishes a Bluetooth connection with the target audio source device among multiple audio source devices that have obtained Bluetooth pairing information from the paired Bluetooth auxiliary connection device, which may further include the following steps: S242. In response to the user's Bluetooth connection operation, when the second real-time distance between the Bluetooth auxiliary connection device and the target audio source device reaches the second preset distance, the paired Bluetooth auxiliary connection device and the target audio source device enter the connection state. S244. When the Bluetooth auxiliary connection device is connected to the target audio source device, the Bluetooth auxiliary connection device is used to allow the target audio source device to read and copy the Bluetooth pairing information obtained by the Bluetooth auxiliary connection device. S246. When the target audio source device obtains Bluetooth pairing information, the Bluetooth playback device and the target audio source device establish a Bluetooth connection based on the Bluetooth pairing information.

[0077] Similarly, in this embodiment, the Bluetooth playback device acts as the implementing entity of step S24, establishing a Bluetooth connection with the target audio source device using a Bluetooth auxiliary connection device. It can be seen that step S24 in this embodiment corresponds to step S14 in the above embodiments, the difference being that the implementing entity of step S14 is the Bluetooth auxiliary connection device, which will not be elaborated further here.

[0078] Furthermore, in step S242, the pairing of the Bluetooth auxiliary connection device and the target audio source device can be further included in the following steps: S2422, enables the Bluetooth auxiliary connection device and the target audio source device to enter a connection state via near field communication; Alternatively, S2424, enables the Bluetooth auxiliary connection device to be detected by the target audio source device via Bluetooth RSSI, so that the target audio source device and the Bluetooth auxiliary connection device enter a connection state. Alternatively, S2426, the Bluetooth auxiliary connection device is used to allow the target audio source device to virtualize itself as the Bluetooth auxiliary connection device, so that the target audio source device and the Bluetooth auxiliary connection device enter a connection state.

[0079] Furthermore, in step S246, the Bluetooth playback device and the target audio source device establish a Bluetooth connection based on the Bluetooth pairing information, which may further include the following steps: S2462, Enables the Bluetooth auxiliary connection device to be used by the target audio source device to copy the Bluetooth connection identity of the Bluetooth auxiliary connection device based on the copied Bluetooth pairing information; S2464. A Bluetooth playback device and a target audio source device with copied Bluetooth connection identity directly establish an A2DP audio connection.

[0080] Furthermore, in step S2464, the Bluetooth playback device and the target audio source device with the copied Bluetooth connection identity directly establish an A2DP audio connection, which may further include the following steps: S24642. The Bluetooth playback device verifies pairing information with the target audio source device that has copied the Bluetooth connection identity. S24644 When the encryption key of the target audio source device is detected to be consistent with the encryption key of the Bluetooth auxiliary connection device, the Bluetooth playback device establishes an A2DP audio connection with the target audio source device.

[0081] Moreover, such as Figure 10 As shown, in step S24, after the Bluetooth playback device establishes a Bluetooth connection with the target audio source device among multiple audio source devices that have obtained Bluetooth pairing information from the paired Bluetooth auxiliary connection device, the following steps may also be included: S26, enabling the Bluetooth auxiliary connection device to provide the target audio source device with real-time detection of the third real-time distance between the Bluetooth auxiliary connection device and the target audio source device; S28. When the third real-time distance reaches the third preset distance, the Bluetooth auxiliary connection device disconnects from the target audio source device, and the Bluetooth playback device disconnects from the target audio source device.

[0082] Similarly, in this embodiment, the Bluetooth playback device acts as the implementing entity for steps S26 and S28. By disconnecting the Bluetooth auxiliary connection device from the target audio source device, the Bluetooth playback device is disconnected from the target audio source device. It can be seen that steps S26 and S28 in this embodiment correspond to steps S16 and S18 in the above embodiments, the difference being that the implementing entity for steps S16 and S18 is the Bluetooth auxiliary connection device, which will not be elaborated further here.

[0083] Furthermore, in step S28, after the Bluetooth playback device disconnects from the target audio source device, the following steps may be further included: S29. In a scenario with multiple audio source devices, in response to the user's Bluetooth connection operation, the Bluetooth playback device establishes a Bluetooth connection with the second target audio source device among the multiple audio source devices that have obtained Bluetooth pairing information from the paired Bluetooth auxiliary connection device.

By connecting and pairing the Bluetooth auxiliary connection device with the second target audio source device, the Bluetooth playback device establishes a Bluetooth connection with the second target audio source device, thereby realizing the connection switching between the Bluetooth playback device and multiple audio source devices. It can be seen that step S29 in this embodiment corresponds to step S19 in the above embodiment, the difference being that the implementing entity of step S19 is the Bluetooth auxiliary connection device, which will not be described further here.
