Description

Technical Field

[0001] The technical solution of the present disclosure relates to the field of device control technology, and in particular, to a data transmission method, a playback device, a storage medium, and an electronic device. Background Art

[0002] When a playback device communicates with a terminal device, the playback device can play the audio in the terminal device. For example, the playback device plays voices in voice calls, ringtones, videos, etc. in the terminal device. This way of playing audio through the playback device can bring an immersive audio playback experience to users.

[0003] In the prior art, the user needs to manually connect the playback device and the terminal device, and the playback device can only execute the audio playback task sent by the terminal device. This communication method is not flexible enough. Summary of the Invention

[0004] In view of this, the present disclosure provides a data transmission method, a playback device, a storage medium, and an electronic device to solve the problem that the communication method between the terminal device and the playback device is not flexible enough.

[0005] According to the first aspect of the embodiments of the present disclosure, a data transmission method is provided. The method includes:

[0006] Receiving an audio playback task sent by a terminal device;

[0007] In response to detecting a sub-playback device, the main playback device synchronizes the audio playback task to the sub-playback device so that the sub-playback device executes the audio playback task.

[0008] According to the second aspect of the embodiments of the present disclosure, a main playback device is provided. The playback device is a main playback device and includes:

[0009] A first communication module for receiving an audio playback task sent by a terminal device;

[0010] A second communication module for synchronizing the audio playback task to the sub-playback device in response to detecting the sub-playback device so that the sub-playback device executes the audio playback task.

[0011] According to the third aspect of the embodiments of the present disclosure, an electronic device is provided, including:

[0012] A processor;

[0013] A memory for storing instructions executable by the processor;

[0014] Wherein, the processor is configured to implement the steps of the data transmission method according to any one of the first aspect by running the executable instructions.

[0015] According to a fourth aspect of the embodiments of the present disclosure, a non-transitory computer-readable storage medium is provided, on which a computer program is stored, and when the program is executed by a processor, the steps of the data transmission method described in any one of the above first aspects are implemented.

[0016] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:

[0017] The main playback device and the terminal device can communicate, so that the main playback device can receive the audio playback task sent by the terminal device. The main playback device plays the corresponding audio by executing this audio playback task.

[0018] When the main playback device detects the sub-playback device, the main playback device and the sub-playback device can communicate with each other. At this time, it is considered that the sub-playback device also wants to execute the current audio playback task, and the main playback device will synchronize the audio playback task to the sub-playback device, so that the sub-playback device can execute the audio playback task.

[0019] When multiple playback devices are desired to execute the audio playback task in a terminal device, it is not necessary to directly connect each playback device to the terminal device in sequence. Each sub-playback device can automatically obtain the audio playback task of the terminal device through the main playback device, which helps to solve the problem that the communication method between the terminal device and the playback device is not flexible enough.

[0020] Furthermore, since the audio playback task is synchronized through the main playback device, the sub-playback devices can be indirectly managed through the main playback device, which helps to solve the problem of difficult management of multiple playback devices.

[0021] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0033] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0034] In the prior art, when a playback device wants to execute an audio playback task in a terminal device, it needs to be connected to the terminal device.

[0035] When the playback device is a wireless playback device (such as Bluetooth speakers, WIFI headphones, Bluetooth headphones, etc.), it is troublesome to connect the wireless playback device to the terminal device. The following takes the Bluetooth playback device as an example to briefly introduce the connection steps:

[0036] a. Turn on the Bluetooth function (especially the Bluetooth search function) on the Bluetooth playback device and terminal device respectively.

[0037] b. Click on the Bluetooth setting option of the terminal device to start searching for nearby Bluetooth devices (usually it takes a while).

[0038] c. Multiple devices were found.

[0039] d. Select the Bluetooth device to be connected and establish a connection.

[0040] It can be seen that this connection method requires users to perform a series of connection operations.

[0041] In actual situations, there are the following scenarios:

[0042] Multiple users participate in online meetings (or participate in video calls, watch movies together, etc.) through a terminal device (such as a conference room computer, conference room Internet TV device, etc.) in the same offline conference room. Generally speaking, the audio will be played through the module built into this terminal device so that the conference content can be played in the conference room.

[0043] However, the audio quality and volume of the built-in module of this terminal device are usually difficult to meet expectations, especially in a conference room where multiple people listen together. In other words, the built-in module of this terminal device is not enough for everyone in the conference room to hear the meeting content clearly.

[0044] Therefore, in the prior art, a sound speaker that can amplify the volume (and improve the sound quality) is usually configured for this terminal device. However, this method cannot fundamentally solve the problem that some participants cannot hear the content of the meeting due to the large number of people in the meeting room or the meeting room is too empty. In addition, when the sound of the sound speaker is loud, it is easy to affect the normal work of people outside the meeting room.

[0045] Based on this, the present disclosure proposes a solution that enables multiple playback devices to perform the audio playback task of the same terminal device, which can solve the above problem.

[0046] ​​Exemplarily, assume that one of the multiple playback devices is a sound externalization device in a meeting room, and the remaining devices are the headphones of one or more participants (or all of the multiple playback devices are headphones). The multiple playback devices can be made to communicate with the terminal device so that the multiple playback devices can all play the audio to be played in the terminal device. In this way, for each participant, if they can clearly hear the sound played by the sound externalization device, they can choose not to wear headphones; if they cannot clearly hear the sound played by the sound externalization device, they can choose to wear headphones; or, without the sound externalization device and everyone wears headphones, so that everyone can clearly hear the meeting content.

[0047] In the prior art, when multiple playback devices all want to execute the audio playback task in the terminal device, each of the multiple playback devices needs to be connected to the terminal device in sequence.

[0048] According to the connection process listed above, it can be seen that the process of connecting one playback device is rather troublesome. As the number of playback devices to be connected increases, this method of connecting each playback device to the terminal device separately becomes more complex and will seriously occupy the meeting time in the above scenario.

[0049] Therefore, in the prior art, this scheme of connecting multiple playback devices to the same terminal device to execute the same audio playback task is usually not adopted. In other words, each user usually does not adopt the scheme of connecting their own headphones to the meeting room computer to listen to the meeting content either.

[0050] To solve the above problems, the present disclosure realizes the communication between the playback device (master) and the terminal device through a master playback device. In this way, the master playback device can receive the audio playback task sent by the terminal device. The audio playback task includes the audio to be played and / or the playback instruction for the audio to be played, so that the master playback device can execute the audio playback task.

[0051] When the master playback device detects a slave playback device, the audio playback task can be synchronized to the slave playback device through the master playback device. In this way, the slave playback device can also execute the audio playback task, enabling the slave playback device to execute the audio playback task (for example, allowing the master playback device and the slave playback device to execute simultaneously or separately; or only allowing the slave playback device to execute).

[0052] There is no limitation on the way the master playback device detects the slave playback device. For example, communication modules are provided in both the master playback device and the slave playback device, enabling both parties to communicate with each other. The communication module can be, for example, a wireless communication module: a Bluetooth module, a Wi-Fi (Wireless Network Communication Technology) module, an NFC (Near Field Communication) module; or, the communication module can also be a wired communication module, etc.

[0053] Taking the NFC module in the communication module as an example, when the main playback device and the sub-playback device are close to each other, the main playback device and the sub-playback device can communicate with each other (for example, exchange device information of both parties), so as to synchronize the audio playback task to the sub-playback device through the device information.

[0054] The following is a detailed introduction:

[0055] Figure 1 It is a flowchart of a data transmission method shown by the present disclosure according to an exemplary embodiment. As Figure 1 shown, the method includes the following steps:

[0056] Step 101, receive an audio playback task sent by a terminal device.

[0057] The method introduced by the present disclosure is applied to the main playback device, or the server or operating system corresponding to the main playback device. The main playback device is a device capable of playing audio, such as headphones, speakers, horns, etc., and can also be a device configured with a display interface, such as a television, a mobile phone, etc.

[0058] The main playback device and the terminal device are communicatively connected. The present disclosure does not limit the connection manner between the main playback device and the terminal device, which can be a Bluetooth connection, a wired connection, a Wi-Fi connection, etc. Through the communication connection manner between the main playback device and the terminal device, the terminal device can send an audio playback task to the main playback device.

[0059] Among them, the audio playback task includes: the audio to be played, and / or, a playback instruction. Exemplarily, the terminal device directly sends the audio to be played to the main playback device, and the main playback device directly plays the audio to be played after receiving it. Or, the terminal device first sends the audio to be played to the main playback device, and then sends control instructions (such as pause, start, rewind, speed up playback) to the main playback device, and the main playback device plays. Or, the terminal device only sends control instructions to the main playback device, and the control instructions indicate the location of the audio to be played or the search path of the audio to be played and other resources.

[0060] Step 102, in response to detecting a sub-playback device, the main playback device synchronizes the audio playback task to the sub-playback device so that the sub-playback device executes the audio playback task.

[0061] Exemplarily, step 102 can be implemented in the following two ways:

[0062] Method 1, wireless communication:

[0063] Figure 2FIG. 0 is a flowchart of another data transmission method shown according to an exemplary embodiment of the present disclosure. As Figure 2 shown, when performing the above step 102 by wireless communication, the following steps are specifically included:

[0064] Step 1021: In response to the wireless communication module of the master playback device being triggered by the wireless communication module of the slave playback device, obtain the device information of the slave playback device.

[0065] The wireless communication module may be a Wi-Fi module, a Bluetooth module, or an NFC module. The master playback device and the slave playback device can discover and establish a connection with each other through the wireless communication module device.

[0066] The device information includes, but is not limited to: device identifier, wireless communication address of the device (such as Wi-Fi address, Bluetooth address, etc.). After obtaining the device information of the playback module (master playback module or slave playback module), the corresponding device can be found based on the device information and communicate with it.

[0067] When the wireless communication modules of the master playback device and the slave playback device both start communication and the master playback device and the slave playback device are close to each other, the master playback device will be triggered by the slave playback device. For example, when both the master playback device and the slave playback device are provided with NFC modules (default is started), the master playback device and the slave playback device will exchange their device information through the NFC module. At this time, the master playback device is triggered by the slave playback device (it can also be considered that the two trigger each other).

[0068] Method 2: Wired communication:

[0069] For example, connect the slave playback device to the master playback device by a wired method (such as a USB data cable), and the master playback device can detect the slave playback device. The master playback device can directly synchronize the audio playback task to the slave playback device through the wired connection.

[0070] Step 1022: The master playback device synchronizes the audio playback task to the slave playback device based on the device information.

[0071] Regardless of which method is used, the audio playback task of the terminal device can be synchronized to the slave playback device through the master playback device. At this time, the slave playback device can execute this audio playback task and play the corresponding audio to be played.

[0072] In the above method, the audio playback task is synchronized to the slave playback device by the master playback device detecting the slave playback device. This communication method between the slave playback device and the terminal device, as well as the execution method of the audio playback task, is more flexible.

[0073] The following provides an exemplary application scenario:

[0074] A movie is being played on the TV set (terminal device) in the living room, and the sound corresponding to the movie is the audio that needs to be played by the playback device (i.e., the audio to be played in the audio execution task).

[0075] The user connects the main playback device (such as a speaker) to the TV set through a wired connection (or wireless communication). In this way, when the TV set is placed against the wall, by placing the main playback device in the center of the living room, each user in the living room can clearly hear the audio to be played corresponding to this movie.

[0076] When user A continues to watch the movie in the living room and user B goes to the kitchen to cook, since the sound in the kitchen is too loud after the range hood is turned on, user B may not be able to clearly hear the audio played by this main playback device.

[0077] At this time, user B can connect their headphones to the TV set through wireless communication so as to be able to synchronously hear the audio to be played in the movie on the TV set.

[0078] However, in this case, the following problems may occur: Since the headphones are directly connected to the TV set, the audio of the main playback device is interrupted, and the audio is changed to be played from user B's headphones. At this time, user A in the living room cannot hear the audio to be played corresponding to the movie through the main playback device. User A may need to reconnect or continue playing the main playback device, or may directly be unable to continue listening.

[0079] Furthermore, even if the connection of user B's headphones to the TV set does not affect the playback of the main playback device, the following may also occur:

[0080] The distance between the kitchen and the TV set is relatively far, the wireless communication distance between the headphones and the TV set cannot be satisfied, resulting in the inability to connect the headphones and the TV set, or the communication quality between the two is poor, etc. At this time, user B still cannot clearly hear the audio to be played.

[0081] To solve the above problems, at this time, user B's headphones can be directly connected to the main playback device through a wired or wireless communication method (for example, the main playback device is placed in the middle position between the kitchen and the TV set), so as to obtain the audio to be played through the main playback device for playback.

[0082] Or, if the TV set only supports wired communication and does not support wireless communication, then the headphones cannot directly communicate with the TV set wirelessly. The main playback device can communicate with the TV set by wire. The main playback device supports both wireless communication and wired communication. Therefore, user B's headphones can be directly connected to the main playback device, so as to play the audio of the movie played on the TV set.

[0083] Optionally, when the main playback device described in step 1022 synchronizes the audio playback task to the sub-playback device based on the device information, the following two methods are included:

[0084] Method 1: Let the terminal device send the audio playback task to the sub-playback device by itself. Specifically:

[0085] The main playback device sends the device information to the terminal device, so that the terminal device communicates with the sub-playback device based on the device information and sends the audio playback task to the sub-playback device.

[0086] After being triggered by the sub-playback device, the main playback device can obtain the device information of the sub-playback device. Since the main playback device and the terminal device communicate with each other, the device information of the sub-playback device can be directly sent to the terminal device.

[0087] At this time, the terminal device can establish communication with the sub-playback device through the device information. In this way, every time the terminal device sends an audio playback task to the main playback device, it also synchronously sends it to the sub-playback device.

[0088] It should be noted that since the terminal device obtains the device information of the sub-playback device through the main playback device, when the terminal device establishes a communication connection with the sub-playback device, the terminal device believes that it needs to communicate with multiple playback devices at this time. That is to say, the terminal device knows that it still needs to communicate with the main playback device and will not disconnect the communication with the main playback device, and there will be no situation where the previously connected playback device (such as the main playback device) disconnects or terminates playback when the terminal device directly communicates with other playback devices (without passing through the main playback device). Or, when the terminal device obtains the device information of the sub-playback device through the main playback device, the priority of the sub-playback device is defaulted to be lower than the priority of the main playback device, so as to realize the management of multiple playback devices, especially to avoid the situation where the main playback device cannot normally execute the audio playback task due to connecting the sub-playback device.

[0089] Exemplarily, when both the main playback device and the sub-playback device are headphones, and the headphones include a headphone case (the headphone and the case can charge the headphone body) and the headphone body, the trigger between the sub-playback device and the headphone of the main playback device is triggered by the proximity of the headphone case (a wireless communication module is set in the headphone case, and the wireless communication module is equipped with near-field communication technology, Bluetooth technology, and / or Wi-Fi technology, etc.). The headphone cases can exchange device information with each other.

[0090] The earphone case of the slave playback device can at least send the address information (Bluetooth address and / or Wi-Fi address) of its own earphone body to the earphone case of the master playback device, and the earphone case of the master playback device sends the address information of the earphone body of the slave playback device to the terminal device, so that the terminal device can directly send the audio playback task to the earphone body of the slave playback device, and let the earphone body of the slave playback device execute the audio playback task.

[0091] This disclosure mainly takes the example that both the earphone body and the earphone case obtain the audio playback task through Wi-Fi communication (the earphone case is also equipped with near-field communication technology, such as an NFC communication module). This communication method has more bandwidth and speed compared with the Bluetooth communication method, so the effect will be better, and it also has topological capabilities.

[0092] Method 2: Without passing through the terminal device, the master playback device directly sends the audio playback task to the slave playback device. Specifically:

[0093] The master playback device sends the audio playback task to the slave playback device indicated by the device information.

[0094] The master playback device does not need to send the device information to the terminal device, that is, there is no need for communication between the terminal device and the slave playback device. This is beneficial for the master playback device to manage one or more slave playback devices. It can avoid the situation that the terminal device does not know which playback devices need to synchronize the audio playback task and which playback devices do not need to synchronize the audio playback task due to the communication between the terminal device and multiple playback devices, resulting in the multiple playback devices being unable to normally execute the audio playback task.

[0095] Exemplarily, when the master playback device and the slave playback device are both earphones, and the earphone includes an earphone case (the earphone case can charge the earphone body) and an earphone body, the trigger between the slave playback device and the earphone of the master playback device is triggered by the proximity of the earphone case (a wireless communication module is set in the earphone case, and the wireless communication module is equipped with near-field communication technology, Bluetooth technology, and / or Wi-Fi technology, etc.). The earphone cases can exchange device information with each other.

[0096] At this time, the device information can be the address information of the earphone case and / or the address information of the earphone body.

[0097] For example, when the device information at least includes the address information of the earphone case, it can be achieved through the following steps:

[0098] Based on the address information, the master playback device sends the audio playback task to the earphone case of the slave playback device, so that the earphone case of the slave playback device forwards the audio playback task to the earphone body of the slave playback device.

[0099] That is to say, the terminal device will send the audio playback task to both the earphone case of the main playback device and the earphone body at the same time. At this time, the earphone body will execute the audio playback task. Meanwhile, the earphone case will forward the audio playback task to the earphone case of the sub-playback device so that the earphone case of the sub-playback device can forward it to the earphone body to execute the audio playback task.

[0100] Alternatively, the terminal device will send the audio playback task to the earphone case of the main playback device, and the earphone case of the main playback device will send the audio playback task to both its own earphone body (of the main playback device) and the earphone case of the sub-playback device at the same time, so that the earphone case of the sub-playback device can forward the audio playback task to the earphone body.

[0101] For another example, when the device information at least includes the address information of the earphone body, it can be achieved through the following steps:

[0102] Based on the address information, the main playback device sends the audio playback task to the earphone body of the sub-playback device.

[0103] At this time, the main playback device can directly synchronize the audio playback task to the earphone body of the sub-playback device (and the earphone body of the main playback device).

[0104] It should be noted that the above Method 1 and Method 2 can be switched with each other. For example, when it is found that communication fails in Method 1, communication can be attempted through Method 2; vice versa, until the audio playback task is successfully synchronized to the sub-playback device.

[0105] For example, in response to the terminal device failing to communicate with the sub-playback device based on the device information, or the terminal device failing to send the audio playback task to the sub-playback device, execute: The main playback device sends the audio playback task to the sub-playback device indicated by the device information.

[0106] In response to the main playback device failing to send the audio playback task to the sub-playback device indicated by the device information, execute:

[0107] The main playback device sends the device information to the terminal device so that the terminal device communicates with the sub-playback device based on the device information and sends the audio playback task to the sub-playback device.

[0108] Optionally, Figure 3 is a flowchart of another data transmission method shown according to an exemplary embodiment of the present disclosure. As Figure 3 shown, when executing step 102, the main playback device synchronizes the audio playback task to the sub-playback device, including the following steps:

[0109] Step 301: Obtain the playback permission of the sub-playback device.

[0110] In response to detecting the sub-playback device, the main playback device determines one or more current audio to be played as the audio to be synchronized; and determines that the sub-playback device has the playback permission to play the audio to be synchronized.

[0111] Exemplarily, assume that when the main playback device detects the sub-playback device, the main playback device is performing the audio playback task A of the terminal device, and the audio specified in the audio playback task A is audio A. At this time, audio A is one or more current audio to be played.

[0112] At this time, it is considered that the sub-playback device has the playback permission to play audio A.

[0113] If after the sub-playback device is connected, the terminal device issues an audio playback task B (specifying to play audio B and audio C), it is considered that the sub-playback device does not have the permission to play audio B and audio C. Only the main playback device plays audio B and audio C.

[0114] In another embodiment, the playback permission can be set by the user. For example, after the main playback device is connected to the sub-playback device, the user is required to configure the corresponding playback permission (such as setting to always have the playback permission for certain applications, etc.).

[0115] Alternatively, the playback permission can be the same as that of the main playback device by default and can be adjusted according to the user's modification, etc.

[0116] Step 302: Synchronize the audio playback task that meets the playback permission to the sub-playback device.

[0117] Exemplarily, when the audio to be played indicated by the audio playback task is the same as the audio to be synchronized, synchronize the audio to be played to the sub-playback device.

[0118] At this time, when the main playback device receives multiple audio playback tasks, it can only synchronize the audio playback tasks that meet the playback permission of the sub-playback device to the sub-playback device. In this way, it can ensure the privacy control of the main playback device over each sub-playback device, ensure that each private audio of the terminal device will not be synchronized to the sub-playback device, and help protect the user's privacy.

[0119] For example, if after the sub-playback device is connected, when the main playback device and the sub-playback device synchronously execute the audio playback task A (playing audio A), a call comes in on the terminal device. At this time, the main playback device (assuming it is the earphone of the owner of the terminal device) can directly answer the call, and only the main playback device can hear the call content (new audio), and will not forward the audio corresponding to this call content to the sub-playback device (which does not have the playback permission).

[0120] Figure 4a This is an application scenario diagram of a data transmission method shown according to an exemplary embodiment of the present disclosure, as Figure 4a shown:

[0121] The terminal device 400 communicates with the earphone case 4011 and the earphone body 4012 of the main playback device 401.

[0122] The earphone case 4011 of the main playback device 401 is connected to the earphone case 4021 of the sub-playback device 402; the earphone case 4021 of the sub-playback device 402 is connected to the earphone body 4022 of the sub-playback device 402.

[0123] Therefore, the earphone body 4022 of the sub-playback device 402 and the earphone body 4012 of the main playback device 401 can synchronously execute the audio playback task.

[0124] It can be noted that the sub-playback device 402 executes the audio playback task by connecting to the main playback device 401. It has the following effects:

[0125] The communication distance between the terminal device and the earphone case is set (for the sake of easy understanding, 10 meters will be used for illustration below, but 10 meters is only an exemplary value and can also be modified to other values). If the earphone body of the sub-playback device directly communicates with the terminal device, the earphone body of the sub-playback device needs to be within 10 meters of the terminal device, that is, the communication distance between the terminal device and the earphone body of the sub-playback device can only reach 10 meters.

[0126] However, according to Figure 4a the way that the earphone case of the sub-playback device shown communicates with the earphone case of the main playback device can extend the communication distance between the earphone body of the sub-playback device and the terminal device.

[0127] The following will be described by way of example in conjunction with Figure 4b and Figure 4c :

[0128] As Figure 4b shown, when the terminal device 400 directly communicates with the earphone body 4012 of the main playback device 401 and the earphone body 4022 of the sub-playback device 402, the longest communication distance between the terminal device and the earphone body 4022 of the sub-playback device is 10 meters.

[0129] As Figure 4c shown:

[0130] The distance between the terminal device 400 and the earphone case 4011 of the main playback device 401 can reach 10 meters.
