Description

A method for allocating channels and related equipment

This application claims the priority of the Chinese patent application filed on September 24, 2020, with the application number 202011014924.9 and the invention titled "A Method for Assigning Sound Channels and Related Equipment", the entire contents of which are incorporated by reference in this application.

technical field

The embodiments of the present application relate to the technical field of multimedia audio, and in particular, to a method for allocating channels and related devices.

Background technique

In pursuit of better sound playback, people often use multiple speakers to create a stereo speaker system. Among them, when creating a stereo speaker system, first set up a speaker network for multiple speakers, that is, multiple speakers (or called slave speakers) are connected to a local area network of one of the speakers (or called master speakers). Next, assign channels to each of the multiple speakers to form a stereo speaker system. When using a stereo speaker system to play audio files, a surround sound field can be formed, a reverberation effect can be produced, and the user can feel immersive.

Generally speaking, after multiple speakers form a speaker network, an electronic device (eg, a mobile phone) can be used to set the channel of each speaker in the multiple speakers, so that the multiple speakers form a stereo speaker system. For example, two speakers and the mobile phone are in the same local area network, and the two speakers form a speaker network. Based on the user's operation on the mobile phone, the left and right channels are set for the two speakers. For example, the first speaker is set as the left channel speaker, and the second speaker is set as the right channel speaker. In this way, the two speakers form a two-channel stereo speaker system. When playing an audio file, the first speaker plays the left channel audio, and the second speaker plays the right channel audio.

In addition, after multiple speakers form a speaker network, you can also set channels for them through the buttons on the speakers, so that multiple speakers form a stereo speaker system. For example, two speakers are in the same local area network, and the two speakers form a stereo speaker network. By operating the keys on the first sound box and the second sound box, the first sound box is set as the left channel sound box, and the second sound box is set as the right channel sound box. In this way, the two speakers form a two-channel stereo speaker system.

The above method of allocating channels is complicated to operate, which makes it more difficult to set channels of a stereo speaker system. Especially for those who operate for the first time, the operation is cumbersome and complicated, and it is not easy to implement.

SUMMARY OF THE INVENTION

The present application provides a method for channel allocation and related equipment, which can reduce the operation mode of channel allocation, so that a stereo sound box group can easily form a stereo sound effect.

In order to realize the above-mentioned technical purpose, the application adopts the following technical solutions:

In a first aspect, the present application provides a method for allocating channels. The method can be applied to a stereo speaker group composed of at least two speakers, and the stereo speaker group includes a first speaker and a second speaker as an example. The method may include: the first speaker acquires the first voice, and determines the direction of the sound source emitting the first voice, where the first voice is used to instruct the first speaker to assign a channel to each speaker in the stereo speaker group. The first speaker configures the channel of the first speaker as the parameter of the first channel and the channel of the second speaker as the parameter of the second channel according to the direction of the sound source of the first voice and the direction of the second speaker . That is, the first speaker can assign channels to each speaker in the stereo speaker group. The first channel can be either the left channel or the right channel. If the first channel is the left channel, the second channel is the right channel; if the first channel is the right channel, the second channel is the left channel.

It can be understood that the first voice is sent by the user, and is used to control the first speaker to assign a channel to each speaker in the stereo speaker group. Therefore, the purpose of allocating channels to each speaker in the stereo speaker group can be achieved by voice, and the operation difficulty of allocating channels is reduced. Moreover, the first sound box may assign channels to the first sound box and the second sound box according to the direction of the user (ie, the direction of the sound source emitting the first voice) and the direction of the second sound box. That is to say, in the method provided by the embodiment of the present application, the direction confirmation can be performed according to the sound source, so as to accurately allocate the channels and provide the user with a better listening experience.

In a possible implementation manner of the first aspect, the first speaker is configured according to the direction of the sound source of the first voice and the direction of the second speaker before configuring the channels of the first speaker and the second speaker.

In this case, the first speaker can issue a voice prompt, and the voice prompt is used to prompt whether to replace the channels of the first speaker and the second speaker.

Wherein, when the position of the second sound box is changed, the stereo sound effect of the stereo sound box may be destroyed. If the first speaker sends out a voice prompt, it prompts the user that the information of each channel in the stereo speaker group can be changed, so that the stereo speaker group can always provide the user with good stereo sound effects.

Exemplarily, when the first speaker determines to replace the voice of the channel of the first speaker and the second speaker, the first speaker can determine the direction in which the user is located according to the voice, and the direction in which the second speaker is located (that is, the second speaker) Moved position), determine the channel of the first speaker and the second speaker.

detailed description

Hereinafter, the terms "first" and "second" are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may expressly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

The embodiment of the present application provides a method for allocating channels, and the method can be applied to an already established stereo speaker group. The stereo speaker group includes at least two speakers. By setting the channel of each speaker in the stereo speaker group, the stereo speaker group forms a surround sound field when playing audio files. By using the method for allocating channels in the embodiments of the present application, the stereo speaker group can assign channels to each speaker in the stereo speaker group according to the instruction of the voice information. It reduces the difficulty of distributing channels for the stereo speaker group, making it easy to form a stereo sound effect for the stereo speaker group.

It can be understood that at least two speakers form a stereo speaker group, and the stereo speaker group includes a master speaker and a plurality of slave speakers (speakers other than the master speaker). The main speaker can interact with the user, and the sound from the speaker is under the control of the main speaker, so that the stereo speaker group can work "like" a speaker.

Generally speaking, after a plurality of speakers are formed into stereo speakers, the channels of the main speakers and the slave speakers can be set by the specific placement angles of the main speakers and the slave speakers. Taking a stereo speaker group composed of two speakers as an example, please refer to FIG. 1A , which is a stereo speaker group composed of two speakers. As shown in FIG. 1A , the first speaker 10 is the master speaker, and the second speaker 11 is the slave speaker. The speaker of the main speaker is facing the direction of the user, and the speaker of the slave speaker is also facing the direction of the user. Based on the user's location, the slave speaker can be set as the left channel and the master speaker as the right channel. In this way, when the stereo speaker group plays an audio file, the audio of the left channel is played from the speaker, and the audio of the right channel is played from the main speaker, so that the stereo speaker group forms a surround sound field.

It can be understood that, in the scenario shown in FIG. 1A , if the orientations of the speakers of the master speaker and the slave speaker are different, the channels of the slave speaker and the master speaker may be inaccurate. It is assumed that the orientation of the speakers of the main speaker is opposite to the direction of the user, and the orientation of the speakers of the slave speakers is the direction facing the user. Therefore, set the master speaker as the left channel and the slave speaker as the right channel, when the stereo speaker group plays audio files, for the user, the left and right channels are reversed.

Combining multiple speakers into a stereo speaker group and assigning the correct channel to each speaker can provide users with good surround sound when playing audio files.

Exemplarily, using the sound source localization provided by the embodiments of the present application, the master speaker can determine the direction of the user and the slave speaker through the sound source localization method, so as to assign channels to the slave speaker and the master speaker. Please refer to FIG. 1B , which is a schematic diagram of a scene using sound source localization. As shown in FIG. 1B , one master speaker 20 and two slave speakers (in FIG. 1B , the first slave speaker 21 and the second slave speaker 22 ) form a stereo speaker group. The master speaker determines the direction of the user based on sound source localization, and determines the direction of the first slave speaker 21 and the second slave speaker 22 through sound source localization. For the master speaker, the first slave speaker 21 is set as the left channel, the second slave speaker 22 is set as the right channel, and the master speaker is set as stereo. In this way, the main speakers in the stereo speaker group can be assigned the correct channel, and, as shown in FIG. 1B , the stereo speaker group plays audio files to form a stereo surround sound field.

Application scenarios of the methods provided by the embodiments of the present application will be described below.

Please refer to FIG. 2 , which is a schematic diagram of an application scenario of the method for allocating channels provided by an embodiment of the present application. As shown in FIG. 2 , it includes an electronic device 100 and a plurality of smart speakers (eg, a first speaker 101 and a second speaker 102 ). The electronic device 100 , the first sound box 101 and the second sound box 102 are all connected to the same local area network, and the electronic device 100 can combine the first sound box 101 and the second sound box 300 into a stereo sound box group. The electronic device 100 combines the first sound box 102 and the second sound box 102 into a stereo sound box group, the first sound box 101 can be set as the master sound box, and the second sound box 102 is the slave sound box. Using the method provided by the embodiment of the present application, a channel can be set for each speaker in the stereo speaker group through the main speaker. In this way, when the stereo speaker group is playing an audio file, a surround sound field is formed, so that the user has an immersive feeling when listening to the sound played by the stereo speaker group.

Exemplarily, when the first speaker 101 and the second speaker 102 form a stereo speaker group, the main speaker can receive the user's "component stereo" voice (or the first voice), and determine the direction of the user according to the voice. The main speaker determines the direction of the slave speaker, and according to the direction of the user and the direction of the slave speaker, the channel is allocated to the master speaker and the slave speaker. For example, according to the direction of the user, the master speaker recognizes that the slave speaker is on the left side of the user, then the master speaker sets the slave speaker as the left channel and the master speaker as the right channel. For another example, the master speaker recognizes that the slave speaker is on the right side of the user according to the direction of the user, and the master speaker sets the slave speaker as the right channel and the master speaker as the left channel.

The method provided by the embodiment of the present application simplifies the way of assigning channels to the stereo speaker group. The main speaker can determine the direction of the user according to the voice according to the received user's voice, and allocate the channels according to the direction of the slave speakers. The operation difficulty of assigning channels in a stereo speaker group is reduced, making it easy to assign channels in a stereo speaker group, thereby forming stereo sound effects when playing audio files.

Please refer to FIG. 4 , which is a schematic diagram of a scenario of a method for allocating channels provided by an embodiment of the present application. The scene shown in FIG. 4 includes: a router 300 , a first sound box 301 , a second sound box 302 and a third sound box 303 . As a gateway device, the router 300 can provide a network access point for the first speaker 301, the second speaker 302 and the third speaker 303, so that the first speaker 301, the second speaker 302 and the third speaker 303 can be accessed through the network access point In the wireless local area network, the first sound box 301, the second sound box 302 and the third sound box 303 can be used normally.

Illustratively, take the first sound box 301 , the second sound box 302 and the third sound box 303 forming a stereo sound box group as an example. Among them, the first speaker 301 is used as a master speaker, and the second speaker 302 and the third speaker 303 are used as slave speakers. When the three speakers form a stereo speaker group, the master speaker acts as a wireless access point (AP), and the slave speakers are all connected to the AP, so that the slave speakers will work under the control of the master speaker.

Specifically, the master speaker can determine the position of the slave speaker through sound source localization, and determine the direction of the user according to the acquired user's voice. The main speakers can assign channels to the main speakers and the slave speakers according to the direction of the user and the direction of the slave speakers.

As shown in FIG. 5A , both the first smart speaker 51 and the second smart speaker 52 include six speakers and microphones corresponding to the speakers. Each speaker can emit sound waves, and each microphone can receive sound waves.

If any speaker on the first smart speaker emits sound waves, the microphone on the second smart speaker can receive the sound waves. For example, the first smart speaker 51 is the main speaker, the microphone of the first smart speaker 51 broadcasts the first sound wave information, and the first sound wave information instructs the smart speaker to broadcast the second sound wave information. The second smart speaker 52 broadcasts the second sound wave information after receiving the first sound wave information. In this way, the first smart speaker 51 can determine the direction in which the second smart speaker 52 is located according to the microphone that receives the second sound wave.

Exemplarily, as shown in FIG. 5B , the first smart speaker 51 and the second smart speaker 52 form a stereo speaker group, and the user is located at the position where S1 is located. The first smart speaker 51 is a master speaker, and the second smart speaker 52 is a slave speaker. The user sends out voice information (ie, the first voice), and the first voice is used to instruct the main speaker to set a channel for each speaker in the stereo speaker group. When the main speaker receives the first voice from the user, the direction of the user can be determined according to the first voice. The main speaker may emit a first sound wave, and the first sound wave is used to instruct the second sound wave to be emitted from the speaker. When the first sound wave is received from the speaker, the second sound wave is sent out, so that the main speaker can determine the direction of the slave speaker according to the second sound wave received. As a result, the main speaker is assigned the left channel to the main speaker and the right channel to the slave speaker from the direction of the speaker according to the direction of the user.

It is understandable that after the user sends out the first voice, the main speaker can set the channel of each speaker in the stereo speaker group according to the first voice, so that the stereo speaker group generates stereo sound effects when playing the audio file.

The method for allocating channels provided by the embodiments of the present application will be described in detail below.

It should be noted that the embodiment of the present application will take the example of a stereo speaker group formed by the first sound box 301 , the second sound box 302 and the third sound box 303 as an example to describe the method for allocating channels provided by the embodiment of the present application. The first sound box 301, the second sound box 302 and the third sound box 303 form a stereo sound box group, and in the case where a stereo sound box has not yet been formed, the method provided by the embodiment of the present application can be used to allocate channels to each sound box, so that the stereo sound box group form stereo.

Please refer to FIG. 6A , which is a flowchart of a method for allocating channels provided by an embodiment of the present application. It should be noted that the flowchart shown in FIG. 6A takes the first speaker 301 and the second speaker 302 to form a stereo speaker group, the first speaker 301 is the master speaker, and the second speaker 302 is the slave speaker as an example to illustrate the combined stereo speaker group. The method of assigning channels in .

Wherein, as shown in FIG. 6A , the method may include steps 601 to 606 .

Step 601: The master speaker and the slave speakers form a stereo speaker group.

Exemplarily, a master speaker and a slave speaker are included in the communicable range of a local area network, and a user can establish a stereo speaker group through an electronic device (eg, a mobile phone). For example, a mobile phone can access a local area network and query the devices connected to the local area network to determine that both the master and slave speakers are connected to the local area network. The user can establish a stereo speaker group through the mobile phone, and the mobile phone can send the information of the component stereo speaker group to the main speaker and the slave speaker, and further through the selection operation of the main speaker and the slave speaker, the main speaker and the slave speaker form a stereo speaker group.

For another example, the main speaker is connected to the local area network through the mobile phone, and the secondary speaker is also connected to the local area network. Determine the formation of a stereo speaker group by selecting the master speaker and the slave speaker (for example, click the button on the master speaker and the slave speaker), and determine the master speaker to be created first by initiating the stereo speaker group, and the receiver created by the stereo speaker group as from the speakers. In this way, the master speaker and the slave speakers form a stereo speaker group.

In another example, the master speaker and the slave speaker may form a stereo speaker group after receiving the voice information. A method of its formation is shown in FIG. 6B , and the method may include steps 61a to 67a.

Step 61a: The user sends voice information, and the voice information is used to instruct the formation of a stereo speaker group.

It is understandable that smart speakers are generally in a dormant state and can monitor the voice information sent by the user at any time. If the voice information is not a wake-up voice to wake up itself (smart speaker) to work, the smart speaker will not respond to the voice information, nor will it record the voice information. voice message.

Exemplarily, the voice information may include a wake-up word, for example, the voice information is "Xiaoyi Xiaoyi, set up a stereo speaker group". This voice message instructs the master speaker and slave speakers to form a stereo speaker group.

In another example, the voice information may not include a wake-up word, for example, the voice information may be "build a stereo speaker group".

Step 62a: The main speaker receives the voice information.

Wherein, as long as the main speaker is in the range where the voice information can be received, the main speaker can receive the voice information and send the voice information according to the position of the user.

Step 63a: Receive voice information from the speaker.

Similarly, as long as the slave speaker is in the receiving range of the voice information, the slave speaker can receive the voice information, and determine the direction of the user according to the voice information.

Step 64a: The main speaker broadcasts the sound waves forming the stereo.

It can be understood that the main speaker may be a speaker that first emits sound waves to form stereo sound after receiving the voice information. Alternatively, the main speakers are preset speakers (eg, the speakers that are connected to the local area network first).

The stereo sound waves broadcast by the main speaker may be the sound that the user can hear or the sound that the user cannot hear.

Step 65a: Receive the sound waves forming the stereo group from the speakers, and broadcast the sound waves connected to the stereo group.

Exemplarily, the voice information sent by the user may be received from the speaker, and the sound waves of the component stereo broadcasted by the main speaker may be received from the speaker, and the slave speaker will access the sound waves of the stereo group in response to the sound waves of the stereo group. This enables the master speaker to receive the access request from the slave speaker, so that the slave speaker can be added to the stereo speaker group.

Step 66a: The master speaker receives the sound waves connected to the stereo group, determines the direction where the slave speakers are located, and determines to form a stereo speaker group with the slave speakers.

It can be understood that the main speaker receives the sound waves broadcast from the speaker and is connected to the stereo group, and determines the direction of the slave speaker. In this way, the master speakers can assign channels to the master speaker and the slave speakers according to the direction of the user, and the direction of the slave speakers.

Step 67a: The main speaker sends out a voice prompt that the stereo speaker group is successfully formed.

Exemplarily, the main speaker may broadcast a voice prompt of "the stereo speaker group is completed", so that the user knows that the creation of the stereo speaker group is completed.

It should be noted that if the master speaker and the slave speakers form a stereo speaker group, the master speaker can be used as an AP device to establish a connection between the slave speaker and the master speaker, and the slave speakers work under the control of the master speaker.

Step 602 : the main speaker acquires the first voice, and determines the direction of the sound source that emits the first voice. The first voice is used to instruct the main speaker to assign a channel to each speaker in the stereo speaker group.

Understandably, when the master speaker and the slave speakers form a stereo speaker group, the master speaker can control the work of the slave speakers. For example, the main speaker can control to receive voice information from the speaker, and transmit the received voice information to the main speaker, and the main speaker responds to the voice information received from the speaker. Alternatively, the slave speaker transmits the received voice information to the master speaker, and the master speaker can determine the response information corresponding to the voice information, and transmit the response information to the slave speaker, and the slave speaker responds to the voice information.

Exemplarily, the first voice may be "build stereo", indicating that the master speaker and the slave speakers form a stereo. Alternatively, the first voice may be "Xiaoyi Xiaoyi, set up stereo". Among them, "Xiaoyi Xiaoyi" here is the wake-up word of smart speakers.

Step 603: The master speaker broadcasts the first sound wave information, and the first sound wave information is used to instruct the slave speaker to broadcast the second sound wave information.

Among them, the master speaker and the slave speakers have been formed into a stereo sound group, and the master speaker uses the sound source positioning method to determine the direction of the slave speakers.

It can be understood that if the stereo speaker group includes multiple slave speakers, the master speaker broadcasts the first sound wave, so that the multiple speakers receive the first sound wave information and broadcast the second sound wave information in response to the first sound wave information. In this way, the master speaker can receive multiple pieces of second sound wave information, so that the directions where the multiple slave speakers are located can be determined according to the received second sound wave information.

Step 604: Receive the first sound wave information from the speaker, and broadcast the second sound wave information in response to the first sound wave information.

Wherein, when the first sound wave information is received from the speaker, it can be recognized that the first sound wave information is sent by the main speaker, and the second sound wave information is requested to be broadcast from the speaker. Therefore, after receiving the first sound wave information from the speaker, the second sound wave information is broadcast. When the main speaker receives the second sound wave information, the main speaker determines the direction of the slave speaker according to the second sound wave information.

Step 605: The master speaker receives the second sound wave information, and determines the direction of the slave speaker.

It should be noted that steps 603 to 605 are based on the method of sound source localization, so that the main speaker determines the direction where the slave speaker is located. For details, reference may also be made to the description of the above-mentioned sound source method. The above-mentioned sound source localization methods can all be applied here, and details are not repeated here.

In some implementations, the master speaker may also locate the distance value from the slave speaker according to the second sound wave information, so as to accurately determine the positional relationship between the slave speaker and the user.

Step 606: According to the direction of the sound source and the direction of the slave speaker, the master speaker sets the master speaker as the first channel and the slave speaker as the second channel.

Exemplarily, the direction of the sound source is the direction of the user. If the main speaker is located in the area on the left side of the user and the slave speaker is located in the area on the right side of the user, the main speaker can be set as the left channel of the main speaker and the right channel of the slave speaker. sound. If the main speaker is located in the area on the right side of the user and the slave speaker is located in the area on the left side of the user, the main speaker can be set as the right channel for the main speaker and the left channel for the slave speaker.

It can be understood that if the stereo speaker group includes three speakers, five speakers, or seven speakers, the master speaker can set multiple channels of the slave speakers according to the directions in which the multiple speakers are located. Makes the stereo speaker group play audio files in stereo, providing users with a good listening experience.

In the first implementation scenario, when the master speaker and the slave speakers form a stereo speaker group, and the master speaker sets the channel of each speaker (ie, the master speaker and the slave speaker) in the stereo speaker group. If the third speaker is added to the stereo speaker group, that is, the main speaker is connected to the first slave speaker and the second slave speaker, the master speaker needs to update the channel of each speaker in the stereo speaker group according to the position of the third speaker.

Exemplarily, the main sound box may send first sound wave information to the third sound box, where the first sound wave information is used to instruct the slave sound box to broadcast the second sound wave information. The first slave speaker and the second slave speaker receive the first sound wave information, and broadcast the second sound wave information in response to the first sound wave information. Sonic information to determine the direction of the first slave speaker and the second slave speaker. The master speaker can set channel parameters for the first slave speaker and the second slave speaker according to the directions of the first slave speaker and the second slave speaker.

In the second implementation scenario, when the master speaker and the slave speakers form a stereo speaker group, and the master speaker sets a channel for each speaker in the stereo speaker group, so that the stereo speaker group forms a stereo sound. If the position of any speaker in the stereo speaker group is changed, the speaker can send an indication message to indicate that the position of itself (ie, the speaker) has changed. In this way, the main speakers can receive the instructions from the speakers.

It can be understood that the indication information can be broadcast from the speaker, or can be sent from the main speaker. That is to say, if the main speaker detects that its position has changed, it also needs to send out a prompt message.

Exemplarily, after receiving the instruction information, the main speaker may issue a voice prompt, where the voice prompt is used to prompt whether to replace the channels of the first speaker and the second speaker. The user can hear the voice prompt broadcast by the master speaker. If the user answers "Yes", the master speaker can set the channel of the master speaker and the slave speaker according to the current position of the slave speaker.

In another example, after the master speaker receives the instruction information, the current position of the speaker is determined, and the channels of the master speaker and the slave speaker are updated according to the positions of the slave speaker and the master speaker.

In the third implementation scenario, when the master speaker and the slave speakers form a stereo speaker group, and the master speaker sets stereo for each speaker in the stereo speaker group. If the user wants to disband the stereo speaker group so that each speaker can work independently, the user can send out a voice message of "disband the stereo speaker group". When the main speaker receives the voice information, the stereo speaker group can be disbanded, so that each speaker can work independently.

The embodiment itself also provides a device for distributing channels, which corresponds to the main speaker in the above-mentioned embodiment. As shown in FIG. 7 , the main speaker includes: an acquisition module 701 , a configuration module 702 , a positioning module 703 , a voice module 704 and a determination module 705 .

The configuration module 702 can be configured to configure the channel of the first speaker as the parameter of the first channel and the channel of the second speaker as the parameter of the first channel according to the direction of the sound source that emits the first sound and the direction of the second speaker. parameters of the two channels.

The positioning module 703 can be used to send the first sound wave information, and the first sound wave information is used to instruct the second sound box to send the second sound wave information; and receive the second sound wave information, and determine the second sound box according to the direction of the second sound wave information. the direction in which it is located.

The voice module 704 can be used to issue a voice description, and the voice prompt is used to prompt whether to replace the channels of the first speaker and the second speaker.

The determining module 705 may be used to determine that the third speaker is added to the stereo speaker group, and the first speaker is used to determine the direction in which the third speaker is located.
