[0038] 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.

[0039] 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.

[0040] The playback device in the present disclosure can be understood as a device that can play sound sources, such as headphones and speakers. The playback device and the sound source providing device transmit data wirelessly (for example, Bluetooth, infrared), so that the playback device can receive data such as sound sources and control information. However, the premise for the sound source providing device to send data to the playback device is that the playback device and the sound source providing device have established a connection.

[0041] The playback device can provide a channel for data transmission (data transmission channel). After the sound source providing device establishes a connection with the data transmission channel of the playback device, the playback device can receive the data sent by the sound source providing device.

[0042] In the related art, when the data transmission channel of the playback device is occupied by one device (device A), the other device (device B) cannot realize the control of the playback device. At this time, if device B wants to control the playback device, it is necessary to operate device A first to exit the connection between device A and the data transmission channel of the playback device, and then connect device B to the data transmission channel of the playback device, so as to realize the control of the playback device by device B. It can be seen that this process requires operating device A and device B at the same time, and the operation process is very cumbersome.

[0043] The device communication method provided by the present application can determine whether the first connection priority corresponding to the second terminal and the first data transmission channel meets the preset conditions when the first data transmission channel of the playback device is connected to the first terminal, and connect the first data transmission channel to the second terminal when the first connection priority meets the preset conditions. That is, by setting the connection priority for the first data transmission channel, when the first data transmission channel of the playback device is already occupied, other devices can also directly achieve connection to the first data transmission channel by sending instructions carrying a priority identifier. In this way, it is also convenient to add or switch control devices for playback devices.

[0044] Figure 1 is a flow chart of a device communication method according to an exemplary embodiment. Figure 1 As shown, the device communication method can be applied to a playback device (eg, earphones, speakers, etc.), and includes the following steps.

[0045] In S11, when the first data transmission channel of the playback device is in a connected state with the first terminal, a connection instruction for the first data transmission channel sent by the second terminal is received.

[0046] In S12, a first connection priority corresponding to the second terminal and the first data transmission channel is determined according to the first priority identifier carried in the connection instruction.

[0047] Here, the priority identifier indicates the connection priority of the first data transmission channel between the sound source providing device and the playing device, and the above-mentioned sound source providing device includes the above-mentioned first terminal and second terminal.

[0048] It can be understood that when the terminal device sends a connection instruction for the first data transmission channel to the playback device, it can carry a priority identifier. Of course, when the first terminal sends a connection instruction to connect to the first data transmission channel, the sent connection instruction can also carry a priority identifier (indicating the connection priority of the first data transmission channel between the terminal and the playback device).

[0049] In S13, when the first connection priority meets a preset condition, it is determined that the first data transmission channel is connected to the second terminal, and it is determined that the first data transmission channel is disconnected from the first terminal.

[0050] In some implementations, when the first connection priority reaches a preset priority, it can be determined that the first connection priority meets the preset condition. Alternatively, when the first connection priority is higher than the priority of the terminal that has been connected to the playback device (for example, the first connection priority is higher than the second connection priority, and the second connection priority indicates the connection priority of the first terminal to the first data transmission channel), it can also be determined that the first connection priority meets the preset condition.

[0051] It can be seen that in the present disclosure, when the first data transmission channel of the playback device is in a connected state with the first terminal, if the playback device receives a connection instruction for the first data transmission channel sent by the second terminal, the first connection priority corresponding to the second terminal and the first data transmission channel can be determined according to the first priority identifier carried in the connection instruction; and whether to connect the second terminal to the first data transmission channel is determined accordingly. In this way, the second terminal can achieve connection with the first data transmission channel of the playback device by controlling the priority identifier carried in the connection instruction, thereby achieving control over the playback device.

[0052] In the related art, when the first terminal is in a connected state with the first data transmission channel of the playback device, it is impossible to establish a connection with the first data transmission channel of the playback device by only sending connection information by the second terminal; this makes it difficult for the second terminal to control the playback device. However, in the method disclosed in the present invention, when the first connection priority indicated by the connection instruction sent by the second terminal meets the preset conditions, the first data transmission channel can be connected to the second terminal; in this way, the connection between the second terminal device and the first data transmission channel can be conveniently and efficiently realized, so that the second terminal can conveniently control the playback device.

[0053] In some implementations, the first data transmission channel can transmit audio sources, control information, etc.

[0054] In some embodiments, when the first connection priority is higher than the second connection priority, it is determined that the first connection priority meets a preset condition.

[0055] Here, the second connection priority indicates the connection priority corresponding to the first data transmission channel and the first terminal.

[0056] In the present disclosure, the switching of the control device corresponding to the playback device can be achieved by setting the priority identifier carried in the connection instruction sent by the first terminal and the second terminal. Figure 2 To illustrate with an example, Figure 2 It can be understood as a possible data flow diagram of the present disclosure:

[0057] In the initial state, the first data transmission channel of the playback device is not connected. When the first terminal needs to be connected to the first data transmission channel of the playback device, the first terminal can generate a connection instruction A and send the connection instruction A to the playback device; at this time, the connection instruction A can carry a priority identifier A indicating a low connection priority; in this way, it is convenient for other devices to obtain control authority over the playback device.

[0058] At this time, if the second terminal needs to be connected to the first data transmission channel of the playback device, the second terminal device can generate a connection instruction B, and the connection instruction B can carry a priority identifier B indicating a high connection priority, so that the second terminal can be connected to the first data transmission channel of the playback device.

[0059] It can be seen that in the present disclosure, by setting the priority identifier carried in the connection instruction sent to the playback device, the terminal connected to the first data transmission channel of the playback device can be switched, thereby conveniently adding or switching the control device for the playback device.

[0060] In some embodiments, the playback device may have a second data transmission channel, and the device communication method may further include:

[0061] In response to determining that the first data transmission channel and the second terminal have completed the connection, generate connection indication information indicating that the first data transmission channel and the second terminal have completed the connection; when the second data transmission channel and the first terminal are in a connected state, send the connection indication information to the first terminal through the second data transmission channel.

[0062] As an example, the playback device may include a first data transmission channel and a second data transmission channel, and the first data transmission channel and the second data transmission channel may be of different models, so that different devices can be easily connected to the playback device.

[0063] It should be understood that different terminal devices support different data transmission channels for connection. For example, the PC (Personal Compute, personal computer or personal computer) may only support connection using the SPP (Serial Port Profile, Bluetooth specification) channel, while mobile terminals (mobile phones, tablets and other devices) may support connection using the AT (AT Command Channel, command voice) channel and the SPP channel. The AT channel and SPP channel here can be understood as data transmission channels. It's just that the SPP channel can transmit more data types and has more efficient and perfect transmission efficiency than the AT channel. The AT channel is mainly used to transmit control instructions. Therefore, the control instructions transmitted by the AT channel may be executed first on the playback device.

[0064] In a possible implementation of the present disclosure, the first data transmission channel of the playback device can be understood as an SPP channel, and the second data transmission channel of the playback device can be understood as an AT channel. After the first data transmission channel is connected by the PC end, the terminal device can also interact with the playback device through the AT channel.

[0065] In order to facilitate understanding of the concept of the present disclosure, the following Figure 3 To explain, Figure 3 It can be understood as a data flow diagram of a possible implementation method of the present disclosure, which is composed of Figure 3 It can be seen that the mobile terminal (using the Android terminal as an example) can send an AT control instruction to the playback device. At this time, the AT control instruction may include an identifier (priority identifier) ​​indicating the connection priority with the SPP channel. At this time, the playback device can determine whether the SPP channel is occupied at this time. If the SPP channel is not occupied, the SPP channel can be connected to the mobile terminal; if the SPP channel is occupied, the connection priority (the connection priority of the terminal to which the SPP channel is connected is compared with the connection priority indicated by the priority identifier) ​​to determine whether to connect the SPP channel of the playback device to the mobile terminal. For example, if the connection priority of the terminal to which the SPP channel is connected is lower than the connection priority indicated by the priority identifier, the SPP channel of the playback device is connected to the mobile terminal; and when the connection priority of the terminal to which the SPP channel is connected is higher than the connection priority indicated by the priority identifier, the mobile terminal is fed back with indication information indicating that the SPP channel connection failed.

[0066] Furthermore, the PC can also send a connection request for the SPP channel to the playback device. When the playback device receives the connection instruction sent by the PC, the judgment process is similar to the above judgment method. For example, if the SPP channel is not occupied, the SPP channel can be connected to the PC; if the SPP channel is occupied, the connection priority can be compared to determine whether to connect the SPP channel of the playback device to the PC.

[0067] It should be noted that usually a mobile terminal can support connection with both an SPP channel and an AT channel. Therefore, the connection instruction for the SPP channel sent by the mobile terminal carries a low priority identifier, while the connection instruction for the SPP channel sent by the PC can carry a high priority identifier. In this way, when the PC needs to use the SPP channel, it can connect to the SPP channel. Since the mobile terminal can also connect to the playback device through the AT channel, the mobile terminal device can also control the playback device.

[0068] The method disclosed in the present invention not only realizes dual control of the playback device, but also, even if the mobile terminal has established a connection with the playback device (the SPP channel has been occupied by the mobile terminal), the PC side can be added to control the playback device, thereby enriching the control of the playback device.

[0069] In some embodiments, the device communication method may further include: in response to receiving the control information, executing a control method indicated by the control information.

[0070] Here, the control information may be generated by the first terminal or the second terminal.

[0071] In the present disclosure, since the first terminal can be connected to the playback device through the second data transmission channel, and the second terminal can be connected to the playback device through the first data transmission channel, the first terminal and the second terminal can both transmit control information to the playback device to control the playback device.

[0072] In some embodiments, when the control information is generated by the first terminal, the first terminal sends the control information using the second data transmission channel; when the control information is generated by the second terminal, the second terminal sends the control information through the first data transmission channel.

[0073] That is, the first terminal and the second terminal each correspond to a data transmission channel, so that the first terminal and the second terminal can both send control information to the playback device to achieve control of the playback device.

[0074] In some embodiments, the device communication method may further include: when the control information is generated by the first terminal and the playback device is currently provided with a sound source by the second terminal, generating first control prompt information corresponding to the control method indicated by the control information, and sending the first control prompt information to the second terminal; or,

[0075] When the control information is generated by the second terminal and the playback device is currently provided with a sound source by the first terminal, second control prompt information corresponding to the control method indicated by the control information is generated, and the second control prompt information is sent to the second terminal.

[0076] It can be understood that when the terminal device sending the control information is different from the terminal device currently providing the sound source, a prompt message that the playback device is controlled can be sent to the terminal device currently providing the sound source. For ease of understanding, an example can be given:

[0077] For example, a mobile terminal is connected to a playback device through an AT channel, and a PC terminal is connected through an SPP channel. If the playback device is playing the sound source provided by the mobile terminal, and the playback device receives a control instruction to pause the music sent by the PC through the SPP channel, then a control prompt message similar to "the current playback is paused by the PC" can be generated to prompt the user of the mobile terminal that the current playback is paused by the PC, so that the user can know the reason why the playback device is paused, making the interaction process clearer.

[0078] It should be noted that in the present disclosure, when the control prompt information is sent to the corresponding terminal, if the control information needs to be sent to the first terminal, the control prompt information can be sent through the second data transmission channel, and when the control information needs to be sent to the second terminal, it can be sent through the first data transmission channel. In this way, after the terminal controls the playback device, there is no need to inform the other terminal (the terminal that previously controlled the playback device) by broadcasting, so that the information transmission between the first terminal and the second terminal can be circulated through the channel provided by the playback device, thereby improving the security of the information transmission process.

[0079] For easier understanding, please refer to Figure 3 When the mobile terminal sends an AT command to the playback device (headphone), the playback device can forward the AT command to the PC through the SPP channel.

[0080] It should be noted that, although the first control prompt information and the second control prompt information are both generated according to the control mode indicated by the control information, the first control prompt information is transmitted to the second terminal via the first data transmission channel, while the second control prompt information is transmitted to the first terminal via the second data transmission channel; therefore, the formats of the first control prompt information and the second control prompt information may be different. The specific formats of the first control prompt information and the second control prompt information can be limited by the formats supported by the first data transmission channel and the second data transmission channel, respectively.

[0081] In some embodiments, the control method includes at least one of the following:

[0082] Noise reduction, turn on gesture operation settings, turn off gesture operation settings, play, pause.

[0083] Of course, in a specific implementation, the specific selection of the above control methods can be limited according to actual conditions.

[0084] In some embodiments, Figure 4 is a flow chart of a device communication method according to an exemplary embodiment. Figure 4As shown, the device communication method can be applied to a first terminal (eg, a mobile terminal). When the first terminal is connected to a first data transmission channel of a playback device, the device communication method can include the following steps.

[0085] In S41, in response to receiving the disconnection prompt information sent by the playback device, it is determined that the first data transmission channel is in a disconnected state, and the disconnection prompt information is displayed.

[0086] Here, the playback device is used to receive a connection instruction for the first data transmission channel sent by the second terminal, determine the first connection priority between the first data transmission channel and the second terminal according to the first priority identifier carried by the connection instruction, and, when the first connection priority meets a preset condition, the playback device is used to determine that the first data transmission channel is connected to the above-mentioned second terminal, and determine that the first data transmission channel is disconnected from the first terminal.

[0087] As an example, after the first data transmission channel of the playback device completes the connection with the second terminal, the playback device can generate a disconnection prompt message and can send the disconnection prompt message to the first terminal to prompt that the first data transmission channel is connected to the second terminal, so that the user of the first terminal is informed that the first data transmission channel is currently disconnected.

[0088] In some embodiments, in response to detecting a connection instruction for a first data transmission channel, a second priority identifier corresponding to the first terminal is determined, wherein the second priority identifier indicates a second connection priority between the first terminal and the first data transmission channel.

[0089] The connection instruction carrying the second priority identifier is sent to the playback device, wherein the playback device is used to determine the connection result between the first data transmission channel and the first terminal according to the second connection priority and the first connection priority, wherein the connection result includes: connection failure or connection success.

[0090] Displays the connection result returned by the playback device.

[0091] Here, when the first data transmission channel is connected to the second terminal, the first terminal may continue to send an instruction to connect to the first data transmission channel so that the first terminal can obtain the connection with the first data transmission channel again.

[0092] In some embodiments, the playback device has a second data transmission channel; and the device communication method may further include:

[0093] When the first terminal is in a connected state with the second data transmission channel, it is determined that the second connection priority indicated by the second priority identifier is lower than a preset priority threshold.

[0094] Here, the first connection priority threshold is higher than or equal to the preset priority threshold; when the first connection priority is higher than the second connection priority, the playback device determines that the first connection priority meets the preset condition.

[0095] As an example, since the first terminal can also be connected to the second data transmission channel of the playback device, the first terminal can also use the second data transmission channel to send a control instruction to the playback device to control the playback device.

[0096] That is, in the present disclosure, the connection priority between the first terminal (mobile phone terminal) and the first data transmission channel (SPP channel) can be set to a low connection priority, while the connection priority between the second terminal (PC terminal) and the first data transmission channel can be set to a high connection priority, thereby facilitating the connection between the second terminal and the first data transmission channel.

[0097] It should be noted that the first terminal can support connection with the AT channel of the playback device, and can also support connection with the SPP channel of the playback device; however, the AT channel can usually connect more efficiently. Therefore, in actual use, the terminal device usually first uses the AT channel to connect to the playback device, and then in order to ensure the comprehensiveness of data transmission, the mobile terminal will continue to generate a connection instruction for connecting to the SPP channel of the playback device; at this time, the connection instruction can carry a second priority identifier (a priority identifier indicating a low connection priority) and be sent to the playback device.

[0098] In some embodiments, the playback device has a second data transmission channel, and the first terminal is connected to the second data transmission channel; and the device communication method further includes:

[0099] Generate control information, and send the control information to the playback device using a second data transmission channel.

[0100] Here, the playback device receives the control information and executes the control method indicated by the control information.

[0101] In some embodiments, the playback device has a second data transmission channel, and the first terminal is connected to the second data transmission channel; and the device communication method may further include:

[0102] Display control prompt information.

[0103] Here, the playback device receives the control information sent by the second terminal through the first data transmission channel, generates control prompt information according to the control mode indicated by the control information, and transmits the control prompt information to the first terminal through the second data transmission channel.

[0104] It can be seen that since the first terminal can be connected to the second data transmission channel of the playback device, both the first terminal and the second terminal can send control information to the playback device, and when the second terminal sends control information to the playback device, the first terminal can also display control prompt information of the control method indicated by the control information, so that the user of the first terminal knows that the second terminal is currently controlling the playback device.

[0105] In some embodiments, Figure 5 is a flow chart of a device communication method according to an exemplary embodiment. Figure 5 As shown, the device communication method can be applied to a second terminal (for example, a PC terminal). When the first data transmission channel between the second terminal and the playback device is in a disconnected state, and the first data transmission channel of the playback device is in a connected state with the first terminal, the device communication method may include the following steps.

[0106] In S51, a first priority identifier corresponding to the second terminal is determined, wherein the first priority identifier indicates a first connection priority between the second terminal and the first data transmission channel.

[0107] In S52, a connection instruction carrying a first priority identifier is sent to the playback device.

[0108] Here, a connection instruction carrying a first priority identifier is sent to the playback device so that the playback device determines that the first data transmission channel is connected to the second terminal and determines that the first data transmission channel is disconnected from the first terminal when the first connection priority indicated by the first priority identifier meets a preset condition.

[0109] As an example, when the first data transmission channel (SPP channel) of the playback device is connected to the first terminal, the second terminal can also obtain the connection with the first data transmission channel of the playback device by sending a connection instruction.

[0110] In some embodiments, when the second terminal is in a connected state with the first data transmission channel, the above-mentioned device control method may also include: generating control information, and sending the control information to the playback device using the first data transmission channel; wherein the playback device receives the control information and executes the control method indicated by the control information.

[0111] As an example, since the second terminal is already connected to the first data transmission channel of the playback device, the second terminal can use the first data transmission channel to send control information to the playback device.

[0112] In some embodiments, when the second terminal is in a connected state with the first data transmission channel, the device control method further includes:

[0113] Display control prompt information.

[0114] Here, the playback device has a second data transmission channel, the playback device receives control information sent by the first terminal through the second data transmission channel, generates control prompt information according to the control method indicated by the control information, and transmits the control prompt information to the second terminal using the first data transmission channel.

[0115] As an example, since the first terminal is connected to the second data transmission channel of the playback device, the first terminal can control the playback device, and when the first terminal controls the playback device, control prompt information is generated according to the control method to prompt the user of the second terminal that the current playback device is controlled by the first terminal.

[0116] In the present disclosure, both the mobile terminal and the PC can provide audio sources to the playback device, that is, both the mobile terminal and the PC can serve as audio source providing devices. Therefore, the playback device may correspond to two control devices. When the playback device receives control information, the control information may not be sent by the current audio source providing device. At this time, a prompt message can be sent to the audio source providing device to inform the audio source providing device that the current playback device has executed the control information.

[0117] For example, when a playback device is playing an audio source provided by a mobile terminal, if it receives a pause command sent by the playback device on the PC, a pause indication message can be generated and sent to the mobile terminal so that the user of the mobile terminal can know that the PC has currently performed a pause operation on the playback device.

[0118] That is, the prompt information can be understood as the user's instruction that the playback device is to be controlled, as well as information such as the specific control method and the control object.

[0119] The connection result may indicate a successful connection or a failed connection. For example, if the audio source providing device is a mobile terminal, when the SPP channel (first data transmission channel) of the playback device is connected to the PC, the mobile terminal may connect to the SPP channel, which may cause the connection to the SPP channel to fail.

[0120] It can be seen that in the present disclosure, the playback device can not only correspond to multiple control devices, but also the playback device can serve as a turnover station for the control information sent by the control device, so that other control devices may also receive the control information. In this way, after the playback device sends a state change, the control device as the playback device can know the reason for the state change, thereby making the interactive experience during use better.
