Description

Technical Field

[0001] The present disclosure relates to the field of wireless audio, and in particular to an audio sharing method, device and medium. Background Art

[0002] LE Audio is a low-power wireless audio technology launched by the Bluetooth Alliance in 2020. It has the characteristics of low latency, low bit rate, and high-quality multi-channel synchronous transmission. From a connection-oriented perspective, it can be divided into Broadcast Media Sender (BMS) and Unicast Media Sender (UMS).

[0003] In the related art, for the LE Audio-UMS solution, devices of the same type (for example, two pairs of headphones of the same model) or devices of different types (for example, headphones of different models) with different coordinated set identifications (CSI) cannot play the same Bluetooth audio at the same time. Summary of the invention

[0004] In order to overcome the problems existing in the related art, the present disclosure provides an audio sharing method, device and medium.

[0005] According to a first aspect of an embodiment of the present disclosure, there is provided an audio sharing method, comprising: in response to detecting that a new audio device has been connected, generating a shared audio request, wherein the shared audio request is used to request that the new audio device be added to a connection synchronization group, wherein the device identifier of the new audio device is different from the device identifier of the audio device already added to the connection synchronization group; receiving a response message to the shared audio request; if the response message indicates agreement to add the new audio device to the connection synchronization group, then adding the new audio device to the connection synchronization group.

[0006] According to a second aspect of an embodiment of the present disclosure, an audio sharing device is provided, comprising: a generating module, for generating a shared audio request in response to detecting that a new audio device has been connected, the shared audio request being used to request that the new audio device be added to a connection synchronization group, wherein the device identifier of the new audio device is different from the device identifier of the audio device already added to the connection synchronization group; a receiving module, for receiving a response message to the shared audio request; and a joining module, for adding the new audio device to the connection synchronization group if the response message indicates agreement to add the new audio device to the connection synchronization group.

[0007] According to a third aspect of an embodiment of the present disclosure, an audio sharing device is provided, comprising: a processor; a memory for storing processor-executable instructions; wherein the processor is configured to implement the steps of any one of the methods described in the first aspect.

[0008] According to a fourth aspect of an embodiment of the present disclosure, a computer-readable storage medium is provided, on which computer program instructions are stored. When the program instructions are executed by a processor, the steps of the audio sharing method provided in the first aspect of the present disclosure are implemented.

[0009] By adopting the above technical solution, since it is possible to generate a shared audio request in response to detecting that a new audio device has been connected, the shared audio request is used to request that the new audio device be added to the connection synchronization group, and the device identifier of the new audio device is different from the device identifier of the audio device already added to the connection synchronization group, and a response message to the shared audio request is received. If the response message indicates that the new audio device is agreed to be added to the connection synchronization group, the new audio device is added to the connection synchronization group. Therefore, it is possible to add devices of the same type with different CSIs or devices of different types to the same connection synchronization group, so that the audio devices in the same connection synchronization group can play the same audio, thereby playing the role of shared audio.

[0010] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0023] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0024] Figure 1 This is a schematic diagram of the LE Audio-UMS solution in the related art. Figure 1 As shown, two pairs of headphones (ie, UMR1 and UMR2) both want to connect to the same UMS for audio playback. If UMR1 and UMR2 are headphones of the same model but have different CSIs, or if UMR1 and UMR2 are headphones of different models, then UMR1 and UMR2 cannot be added to the same Connected Isochronous Group (CIG). That is, devices of the same type or different types with different CSIs cannot be added to the same CIG. Figure 1 As shown, UMR1 can only be added to CIG1, and UMR2 can only be added to CIG2, and CIG1 and CIG2 are two different CIGs. This results in different devices (e.g., devices of the same type with different CSIs, devices of different types, etc.) being unable to play the same Bluetooth audio at the same time.

[0025] Figure 2 1 is a flowchart of an audio sharing method according to an exemplary embodiment. The audio sharing method according to the embodiment of the present disclosure can be applied to an audio transmitter, wherein the audio transmitter refers to a device connected to an audio device so that the audio device plays the audio in the audio transmitter. For example, the audio transmitter can be a TV, a mobile phone, etc., and there is audio that needs to be played in the TV, the mobile phone, etc.; the audio device can be a headset, a speaker, etc.

[0026] like Figure 2 As shown, the audio sharing method may include the following steps S21 to S23.

[0027] In step S21, in response to detecting that a new audio device has been connected, a shared audio request is generated, wherein the shared audio request is used to request that the new audio device be added to a connection synchronization group, wherein the device identifier of the new audio device is different from the device identifier of the audio device already added to the connection synchronization group.

[0028] The device identifier is used to uniquely identify the audio device. For example, the device identifier can be a set identity resolving key (SIRK). For a set of audio devices, each audio device in the set has the same SIRK. For example, for a pair of headphones, the SIRK of the left headphone and the right headphone are the same.

[0029] In some embodiments, generating the audio sharing request may be implemented by presenting a user interface to the user, and asking the user in the user interface whether to agree to share the audio. Figure 3 is a schematic diagram of a user interface for sending a request to share audio to a user according to an embodiment of the present disclosure. If the user agrees to the request to share audio, the user can select Figure 3 If the user disagrees with the request to share the audio, they can select the "Agree" option in Figure 3 The "Cancel" option in the Figure 3 The user interface is for illustration only and does not constitute a limitation to the present disclosure.

[0030] In some embodiments, generating a shared audio request can also be achieved in the following manner: sending a shared audio request to a processor that processes the shared audio request, and the processor can process the shared audio request according to preset rules. For example, the number of package devices allowed in the same CIG group can be preset, and then, after receiving the shared audio request, the processor can first determine whether the number of package devices that have been added to the CIG group has reached the preset number. If the number of package devices that have been added to the CIG group has reached the preset number, the processor can reject the shared audio request. If the number of package devices that have been added to the CIG group has not reached the preset number, the processor can agree to the shared audio request. The processor can be located in the audio transmitter.

[0031] In step S22, a response message to the audio sharing request is received.

[0032] In some embodiments, when a request to share audio is sent to a user through a user interface, a response message to the request to share audio returned by the user through the user interface may be received.

[0033] In some embodiments, when the shared audio request is sent to a processor that processes the shared audio request, a response message to the shared audio request may be received from the processor.

[0034] In step S23, if the response message indicates that the new audio device is agreed to be added to the connection synchronization group, the new audio device is added to the connection synchronization group.

[0035] If the response message indicates that adding the new audio device to the connection synchronization group is not agreed, the new audio device is not added to the connection synchronization group.

[0036] By adopting the above technical solution, since it is possible to generate a shared audio request in response to detecting that a new audio device has been connected, the shared audio request is used to request that the new audio device be added to the connection synchronization group, and the device identification of the new audio device is different from the device identification of the audio device that has been added to the connection synchronization group, and receive a response message to the shared audio request. If the response message indicates that the new audio device is agreed to be added to the connection synchronization group, the new audio device is added to the connection synchronization group. Therefore, it is possible to add devices of the same type with different CSIs or devices of different types to the same CIG group, so that the audio devices in the same CIG group can play the same audio and play the role of shared audio. It should be noted that the audio here can be Bluetooth audio, or it can be wired or wireless audio. That is to say, the audio sharing method according to the embodiment of the present disclosure can be applied not only to the Bluetooth audio field, but also to other fields where audio sharing is required.

[0037] Figure 4 FIG. 1 is a schematic diagram of joining the same CIG group according to an embodiment of the present disclosure. Figure 4 As shown, two pairs of headphones (i.e., UMR1 and UMR2) both want to connect to the same UMS for audio playback, although UMR1 and UMR2 are headphones of the same model but have different CSIs, or although UMR1 and UMR2 are headphones of different models, by adopting the audio sharing method according to the embodiment of the present disclosure, UMR1 and UMR2 are added to the same CIG group (i.e., CIG3), that is, by adopting the audio sharing method according to the embodiment of the present disclosure, devices of the same type or devices of different types with different CSIs can all be added to the same CIG group. In this way, audio devices in the same CIG group can play the same audio, thereby playing the role of sharing audio.

[0038] Figure 5 FIG. 1 is another schematic diagram of joining the same CIG group according to an embodiment of the present disclosure. Figure 5As shown, UMR1 to UMR4 are speakers of different models with different CSIs. By adopting the audio sharing method according to the embodiment of the present disclosure, UMR1 to UMR4 are added to the same CIG group (i.e., CIG1). In this way, UMR1 to UMR4 can be used to play the right rear, left rear, right, and left channel audio of the UMS respectively, and the UMS itself can be used to play the middle channel audio to form a 5.1 channel. That is, a total of 5 independent connected isochronous streams (CIS) are created using UMR1 to UMR4 and the UMS itself. In this way, audio devices in the same CIG group can play the same audio and play the role of sharing audio.

[0039] Figure 6 FIG. 1 is another flow chart of an audio sharing method according to an embodiment of the present disclosure. Figure 6 As shown, the audio sharing method includes steps S61 to S66.

[0040] In step S61, it is detected whether a new audio device is connected.

[0041] For example, it can be detected whether a new audio device is connected to the audio transmitter. The audio transmitter refers to a device in which audio needs to be played. For example, the audio transmitter can be a television, a mobile phone, etc.

[0042] In some embodiments, whether a new audio device is connected can be detected by detecting whether an asynchronous connection-oriented link (ACL) is successfully connected.

[0043] In step S62, if it is detected that a new audio device is connected, the device identification of the new audio device is obtained, and it is determined whether there is an audio device that has been added in the connection synchronization group.

[0044] The device identifier is used to uniquely identify the audio device. For example, the device identifier can be a set identity resolving key (SIRK). For a set of audio devices, each audio device in the set has the same SIRK. For example, for a pair of headphones, the SIRK of the left headphone and the right headphone are the same.

[0045] In some embodiments, for an audio device and an audio transmitter connected via Bluetooth, after the audio device and the audio transmitter ACL are successfully connected, a Coordinated Set Identification Service (CSIS) can be obtained through a Generic Attribute Profile (GATT) protocol, and a device identification (e.g., SIRK) of the audio device can be obtained through CSIS.

[0046] In step S63, if it is determined that the added audio device exists in the connection synchronization group, it is determined whether the device identification of the added audio device is the same as the device identification of the new audio device.

[0047] For example, the device identification of the added audio device is compared with the device identification of the new audio device to determine whether the device identification of the added audio device is the same as the device identification of the new audio device.

[0048] In step S64, if it is determined that the device identification of the added audio device is different from the device identification of the new audio device, a shared audio request is generated, where the shared audio request is used to request that the new audio device be added to the connection synchronization group.

[0049] In step S65, a response message to the audio sharing request is received.

[0050] In step S66, if the response message indicates that the new audio device is agreed to be added to the connection synchronization group, the new audio device is added to the connection synchronization group.

[0051] By adopting the above technical solution, since it is possible to generate a shared audio request when it is determined that the device identifier of the already added audio device is different from the device identifier of the new audio device, the shared audio request is used to request that the new audio device be added to the connection synchronization group, and a response message to the shared audio request is received. If the response message indicates that the new audio device is agreed to be added to the connection synchronization group, the new audio device is added to the connection synchronization group. Therefore, it is possible to add devices of the same type with different CSIs or devices of different types to the same CIG group. In this way, audio devices in the same CIG group can play the same audio, thereby playing the role of shared audio.

[0052] Further references Figure 6According to the embodiment of the present disclosure, the audio sharing method may further include step S67: if it is determined that the device identifier of the added audio device is the same as the device identifier of the new audio device, the new audio device is added to the connection synchronization group.

[0053] For example, for a pair of headphones, the left earphone has been added to the connection synchronization group before, and then after the right earphone is connected to the audio transmitter, it can be determined that the device identifier of the newly connected right earphone is the same as the device identifier of the left earphone that has been added to the connection synchronization group before, so the newly connected right earphone can be directly added to the same connection synchronization group as the left earphone.

[0054] By adopting the above technical solution, when it is determined that the device identifier of the added audio device is the same as the device identifier of the new audio device, the new audio device can be directly added to the connection synchronization group without generating a shared audio request.

[0055] Further references Figure 6 According to the embodiment of the present disclosure, the audio sharing method may further include step S68: if it is determined that there is no audio device that has been added in the connection synchronization group, then the new audio device is added to the connection synchronization group. In this way, the new audio device can be directly added to the connection synchronization group without generating a shared audio request.

[0056] In some embodiments, the audio sharing method according to the embodiment of the present disclosure may further include: if the response message indicates that the new audio device is agreed to be added to the connection synchronization group, updating the number of members in the connection synchronization group.

[0057] When the number of members in the connection synchronization group is updated, the number of members in the connection synchronization group can be updated according to the number of devices in the set to which the audio device belongs. For example, a set of headphones usually has two left and right headphones, that is, the number of devices in a set of audio devices is 2. If the audio device to be added to the same connection synchronization group is a headphone, the number of members in the connection synchronization group is increased by 2.

[0058] In some embodiments, the updating of the number of members in the connection synchronization group may include: switching the state of the audio transmitter to a member configuration state, the audio transmitter being a device connected to the audio device so that the audio device plays the audio in the audio transmitter; in the member configuration state, updating the number of members in the connection synchronization group. That is, the number of members in the connection synchronization group needs to be updated when the audio transmitter is in the member configuration state.

[0059] In some embodiments, switching the state of the audio transmitter to the member configuration state includes: if the current state of the audio transmitter is a QoS configuration state, directly switching from the QoS configuration state to the member configuration state. The QoS configuration state is a state for configuring the quality of service (QoS) of the audio transmitter.

[0060] In some embodiments, switching the state of the audio transmitter to the member configuration state includes: if the current state of the audio transmitter is a streaming state, switching from the streaming state to the QoS configuration state, and switching from the QoS configuration state to the member configuration state. The streaming state is a state of performing streaming (e.g., audio playback, video playback, etc.).

[0061] Figure 7 : is a state switching schematic diagram according to an embodiment of the present disclosure. Generally, the initial state of the audio transmitter may be one of the streaming playback state and the QoS configuration state. If the initial state of the audio transmitter is the streaming playback state, the audio transmitter needs to switch from the streaming playback state to the QoS configuration state and then to the member configuration state to configure the number of members in the connection synchronization group. If the initial state of the audio transmitter is the QoS configuration state, the audio transmitter needs to switch from the QoS configuration state to the member configuration state to configure the number of members in the connection synchronization group.

[0062] In addition, after the number of members is configured, if the audio transmitter needs to switch to the QoS configuration state, it can directly switch from the member configuration state to the QoS configuration state; if the audio transmitter needs to switch to the streaming playback state, it needs to first switch from the member configuration state to the QoS configuration state, and then from the QoS configuration state to the enabled state, and then from the enabled state to the streaming playback state.

[0063] In addition, metadata can be updated in both the enabled state and the streaming state. Moreover, the release operation can be used to enter the release state from the QoS configuration state, the streaming state, or the enabled state. If the audio transmitter is currently in the idle state, it can directly switch from the idle state to the member configuration state to configure the number of members in the connection synchronization group.

[0064] By adopting the above technical solution, when the response message indicates that the new audio device is agreed to be added to the connection synchronization group, the number of members in the connection synchronization group is updated, thereby reducing the performance overhead in the non-audio sharing state. For example, in the Bluetooth audio sharing scenario, the Bluetooth performance overhead in the non-audio sharing state is reduced.

[0065] Figure 8 is a block diagram of an audio sharing device according to an exemplary embodiment. Figure 8 The audio sharing device 8 includes: a generating module 81, which is used to generate a shared audio request in response to detecting that a new audio device has been connected, wherein the shared audio request is used to request that the new audio device be added to a connection synchronization group, and the device identifier of the new audio device is different from the device identifier of the audio device already added to the connection synchronization group; a receiving module 82, which is used to receive a response message to the shared audio request; and a joining module 82, which is used to add the new audio device to the connection synchronization group if the response message indicates that the new audio device is agreed to be added to the connection synchronization group.

[0066] By adopting the above technical solution, since it is possible to generate a shared audio request in response to detecting that a new audio device has been connected, the shared audio request is used to request that the new audio device be added to the connection synchronization group, and the device identification of the new audio device is different from the device identification of the audio device that has been added to the connection synchronization group, and receive a response message to the shared audio request. If the response message indicates that the new audio device is agreed to be added to the connection synchronization group, the new audio device is added to the connection synchronization group. Therefore, it is possible to add devices of the same type with different CSIs or devices of different types to the same CIG group, so that the audio devices in the same CIG group can play the same audio and play the role of shared audio. It should be noted that the audio here can be Bluetooth audio, or it can be wired or wireless audio. That is to say, the audio sharing device according to the embodiment of the present disclosure can be applied not only to the Bluetooth audio field, but also to other fields where audio sharing is required.

[0070] The generating module 81 is further configured to generate the audio sharing request if it is determined that the device identification of the added audio device is different from the device identification of the new audio device.

[0071] Optionally, the adding module 82 is further configured to: if it is determined that the device identifier of the already added audio device is the same as the device identifier of the new audio device, add the new audio device to the connection synchronization group.

[0072] Optionally, the audio sharing device 8 further comprises a configuration module, which is used to update the number of members in the connection synchronization group if the response message indicates that the new audio device is agreed to be added to the connection synchronization group.

[0073] Optionally, the configuration module updates the number of members in the connection synchronization group, including:

[0074] Switching the state of the audio transmitter to a member configuration state, the audio transmitter being a device connected to the audio device so that the audio device plays the audio in the audio transmitter;

[0075] In the member configuration state, the number of members in the connection synchronization group is updated.

[0076] Optionally, the configuration module switches the state of the audio transmitter to a member configuration state, including:

[0077] If the current state of the audio transmitter is the QoS configuration state, the QoS configuration state is directly switched to the member configuration state.

[0078] Optionally, the configuration module switches the state of the audio transmitter to a member configuration state, including:

[0079] If the current state of the audio transmitter is a streaming playback state, the streaming playback state is switched to a QoS configuration state, and then the QoS configuration state is switched to the member configuration state.
