Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

At present, the screen projection function is widely applied in life, and a user can project contents displayed in one device to another device for display and can transmit audio data to another device for playing. For example, when a user plays a video through a smart phone, the video played on the mobile terminal can be projected to another device (e.g., a smart television) for display, and audio data of the video is transmitted to another device for playing, so that the user can have better video watching experience; for another example, when the user plays music through the smart watch, the user may project the audio playing interface displayed on the smart watch onto the computer for displaying, and output the played music through the computer.

Gradually, some electronic devices can display contents projected by multiple devices and play audio data input by the multiple devices, but when playing audio data input by the multiple devices, the electronic devices usually mix and output the audio input by the multiple devices, but when playing the audio data after mixing, a user cannot distinguish the audio input by each device, which causes a confusing feeling, and a poor playing effect is caused.

In view of the above problems, the inventor proposes an audio playing method, an audio playing apparatus, an electronic device, and a storage medium provided in the embodiments of the present application, which can allocate different audio output channels to different audio input devices, so as to facilitate a user to clearly distinguish sounds input by different audio input devices, thereby improving user experience. The specific audio playing method is described in detail in the following embodiments.

An application environment of the video rendering method provided by the embodiment of the present application is described below.

Referring to fig. 1, fig. 1 shows an architecture diagram of an application scenario for an embodiment of the present application, which may include an electronic device 100 and a plurality of input devices 200. The electronic device 100 may be a smart television as shown in fig. 1, and of course, the electronic device 100 may also be other devices with a display function, for example, a desktop computer, a notebook computer, and the like, which is not limited herein. The input device 200 may be a smart phone, a tablet computer, a smart watch, a computer, or the like. In this application scenario, the input device 200 may serve as a resource providing device, and project the display content to the electronic device 100 for display, and of course, the input device 200 may also transmit the audio content to the electronic device 100 for playing.

In some embodiments, electronic device 100 and input device 200 may communicate to accomplish data interaction. The electronic device 100 and the input device 200 may communicate via a Local Area Network (LAN) or a Wide Area Network (WAN). For example, the electronic device 100 and the input device 200 may be connected to a router at the same time, and the electronic device 100 and the input device 200 may communicate through a local area network provided by the router; for another example, the electronic device 100 and the input device 200 may communicate with a cloud, and implement data interaction between the two through the cloud; for another example, the electronic device 100 and the input device 200 may also establish an end-to-end network connection (i.e., a P2P network connection) through a communication manner such as bluetooth, Zigbee, WebRTC, and the like, and perform communication through the established network connection. Of course, the communication mode between the electronic device 100 and the input device 200 may not be limited.

In some scenarios, the electronic device 100 may be a large-screen device (e.g., a smart television shown in fig. 1), and a user may project display content on a small-screen device such as a smart phone, a tablet computer, and a smart watch to the large-screen device for displaying, so as to improve experience of the user when viewing the display content. In addition, the electronic device 100 can receive the content projected by the plurality of input devices 200 at the same time and display the content projected by the plurality of input devices 200, so that the content projected by the plurality of input devices 200 can be displayed on the electronic device 100, a user can view the content projected by the plurality of input devices 200 at the same time, and user experience is greatly improved.

In some embodiments, the electronic device 100 may perform a display layout (for example, a layout position, a size of a display area, and the like) on the display contents input by the plurality of input devices according to the received display contents of the plurality of input devices 100, and then render the display contents input by the plurality of input devices based on the display layout and then display the rendered display contents on the display screen.

In some embodiments, the electronic device 100 may include a content receiving module, a first capability negotiation module, a layout generation module, and a display rendering module; the input device 200 may include a content acquisition module, a content transmission module, and a second capability negotiation module.

Meanwhile, the second capability negotiation module of the input device 200 and the first capability negotiation module of the electronic device 100 are responsible for negotiating the software and hardware capabilities of both parties, and at the same time, the electronic device 100 dynamically negotiates optimal display parameters (such as resolution/bit rate/frame rate) according to the path number of the current picture, that is, the size of the display area, and feeds back the optimal display parameters to the input device 200 for adaptive adjustment. The layout generating module of the electronic device 100 dynamically generates a display layout according to the layout principle by comprehensively considering various factors according to the current constraint conditions (e.g., the number of the input devices connected, the display parameter information of the input devices, the display parameter information of the electronic device, etc.). After the current layout mode is generated, the display rendering module draws and displays the content to be displayed according to the layout.

Referring to fig. 2, the electronic device 100 may include at least one built-in first audio output device 140 and at least one external second audio output device 150. Wherein the first audio output device 141 comprises at least one first audio output channel 142 and the second audio output device 143 comprises at least one second audio output channel 144.

The electronic device 100 may output sound through the audio output channels of the above audio output apparatuses, and when the electronic device 100 receives and outputs audio data input by the plurality of input devices 200, the electronic device 100 may allocate at least one audio output channel of at least one audio output apparatus to the plurality of input devices 200, and ensure that the audio output channels allocated to each input device 200 are different, so that the audio data of each input device 200 may not share the same audio output channel to output the audio data, and a user may distinguish sounds corresponding to the audio data of different input devices.

Referring to fig. 3, fig. 3 is a flowchart illustrating an audio playing method according to an embodiment of the present application. In a specific embodiment, the audio playing method is applied to the audio playing apparatus 400 shown in fig. 18 and the electronic device 100 (fig. 19) equipped with the audio playing apparatus 400. The electronic equipment comprises at least one built-in audio output device and at least one external audio output device, wherein the audio output devices comprise a plurality of audio output sound channels. The following will describe a specific flow of the embodiment by taking an electronic device as an example, and it is understood that the electronic device applied in the embodiment may be a smart television, a notebook computer, a desktop computer, and the like, which is not limited herein. As will be described in detail with respect to the flow shown in fig. 3, the audio playing method may specifically include the following steps:

step S110: and acquiring a plurality of audio input devices and the number of the audio output devices, wherein the number of the audio input devices is used as a first number, and the number of the audio output devices is used as a second number.

In this embodiment, the electronic device may receive input audio data from a plurality of audio input devices, and play the received audio data based on an audio output channel of a built-in audio output apparatus and an external audio output apparatus.

In some embodiments, the audio input device may be an input device in a screen-projection scene, and the audio input device may input audio data to the electronic device for playing, or may input display content to the electronic device for displaying.

In some implementations, the electronic device can establish a network connection with the respective audio input device to receive input data from the audio input device according to the established network connection. The electronic device may establish a network connection with the audio input device in a wireless communication manner, for example, the network connection may be established in a bluetooth manner, a WiFi network manner, and the specific communication manner may not be limited.

For example, when the electronic device establishes a network connection with the audio input device through a WiFi network, the electronic device may display a device list under the same WiFi network, detect a selection operation of the device by the user, and establish a network connection with the device selected by the user according to the detected selection operation. Similarly, the network connection between the electronic device and the audio input device may also be established according to the operation of the user on the audio input device, for the audio input device, such as a smart phone, the audio input device may also display a device list of the electronic devices in the same WiFi network, then detect the selection operation of the user on the device, and establish the network connection with the electronic device selected by the user according to the detected selection operation.

In this embodiment of the application, when the electronic device plays audio data input by the audio input device, the number of the audio input devices that input the audio data at this time and the number of the audio output apparatuses of the electronic device may be determined, so as to allocate audio output channels corresponding to the audio input device according to the determined number of the audio input devices and the determined number of the audio output apparatuses. Wherein the determined number of audio input devices may be a first number and the determined number of audio output apparatuses may be a second number.

In some implementations, the electronic device can determine the number of audio input devices based on the audio input devices currently having a network connection established. The electronic equipment can detect the external audio output devices, determine the number of the built-in audio output devices, and then obtain the sum of the number of the external audio output devices and the number of the built-in audio output devices, namely obtain the number of the audio output devices. As one mode, when the electronic device establishes a network connection with the audio input device, the audio input device does not necessarily start to project a screen or input audio to the electronic device, so that the electronic device may determine the number of the audio input devices that actually perform screen projection or input audio data to the electronic device, for example, the electronic device may determine the number of the audio input devices that send a screen projection instruction to the electronic device and establish a network connection with the electronic device.

Step S120: assigning at least one audio output channel of at least one audio output device to each audio input device based on the first number and the second number, wherein the assigned audio output channels are different for each audio input device.

In this embodiment, after determining the number of the audio input devices and the number of the audio output apparatuses, the electronic device may allocate audio output channels to the audio input devices according to the first number and the second number. Wherein the electronic device may assign at least one audio output channel of the at least one audio output means to each audio input device based on the first number and the second number.

In some embodiments, the electronic device may try to ensure that all audio output channels of one audio output device are allocated to the audio input device according to a principle of preferentially allocating the entire audio output device to the audio input device; when the number of the audio output devices cannot guarantee that all audio output channels of one audio output device can be allocated to the audio input devices, different channels of the audio output device are allocated to different audio input devices, and it is guaranteed that the audio output channels allocated to each audio input device are different, so that at least part of audio data of the audio input devices can be played by the complete audio output device (namely all channels of the audio output device are used for playing the audio data of one audio input device), and a user can conveniently distinguish playing sounds corresponding to the audio data of different audio input devices.

Step S130: and acquiring audio data transmitted by the plurality of audio input devices.

In the embodiment of the present application, after the electronic device allocates the audio output channel to each audio input device, the electronic device may acquire the audio data input by the audio input devices for playing. The electronic device can receive the audio data transmitted by the audio input device according to the network connection established with the audio input device, namely, the audio data to be played is obtained. In some embodiments, the audio data input by the audio input device may be audio data of music, video, game, and the like, which is not limited herein.

Step S140: and playing the audio data transmitted by each audio input device based on the audio output channel allocated to each audio input device.

In this embodiment of the application, after acquiring the audio data input by the multiple audio input devices, the electronic device may demultiplex the audio data, decode the audio data, and play the audio data transmitted by each audio input device according to the audio output channel allocated to each audio input device.

According to the audio playing method provided by the embodiment of the application, at least one audio output channel of at least one audio output device is allocated to each audio input device according to the number of the audio input devices and the number of the audio output devices, then the audio data transmitted by the plurality of audio input devices is obtained, and the audio data transmitted by each audio input device is played based on the audio output channels allocated to each audio input device, so that different audio output channels are allocated to different audio input devices, a user can conveniently and clearly distinguish sounds input by different audio input devices, and the user experience is improved. In addition, because the electronic equipment is not only internally provided with the audio output device, but also externally connected with the audio output device, and each audio output device comprises a plurality of audio output channels, when the number of the audio input equipment is large, the audio data input by the audio input equipment can be ensured to be played on different audio output channels, and the sound playing effect is improved.

Referring to fig. 4, fig. 4 is a flowchart illustrating an audio playing method according to another embodiment of the present application. The audio playing method is applied to the electronic device, and will be described in detail with reference to the flow shown in fig. 4, where the audio playing method may specifically include the following steps:

step S200: and acquiring a plurality of audio input devices and the number of the audio output devices, wherein the number of the audio input devices is used as a first number, and the number of the audio output devices is used as a second number.

In the embodiment of the present application, the step S200 may refer to the contents of the foregoing embodiments, and is not described herein again.

Step S210: it is determined whether the second number is greater than the first number.

In this embodiment, the electronic device may ensure that all audio output channels of one audio output device are allocated to the audio input device as much as possible according to a principle that the entire audio output device is preferentially allocated to the audio input device. After acquiring the first number of audio input devices and the second number of audio output devices, the electronic device may compare the second number with the first number, and then determine whether the second number is smaller than the first number according to a comparison result. It is understood that if the second number is greater than or equal to the first number, it means that the number of audio output devices is greater than or equal to the number of audio input devices, and thus each audio input device can be assigned to at least one complete audio output device; if the second number is smaller than the first number, it means that the number of audio output devices is smaller than the number of audio input devices, and thus it cannot be guaranteed that each audio input device can be assigned to at least one complete audio output device.

Step S220: if the second number is greater than or equal to the first number, all audio output channels of at least one audio output device are allocated to each audio input device.

In this embodiment, if the electronic device determines that the second number is greater than or equal to the first number, the number of the audio output apparatuses at this time may ensure that each audio input device is allocated to obtain at least one complete audio output apparatus, that is, for one audio input device, all audio output channels of the allocated audio output apparatus are used for playing the audio data of the audio input device. In this case, therefore, the electronic device may assign all audio output channels of at least one audio output apparatus to each audio input device and ensure that the assigned audio output apparatuses are different for each audio input device.

For example, referring to fig. 5, when the number of the audio input devices 200 is 1 and the audio output devices include the first audio output device 140a and the second audio output device 140b, the number of the audio output devices is 2, and the number of the audio input devices is 1, so that the first audio output device 140a and the second audio output device 140b can be allocated to the audio input device 200, and the audio data input by the audio input device 200 can be played by all the audio output channels of the first audio output device 140a and the second audio output device 140b at the same time.

For example, referring to fig. 6, the audio input device includes: the audio output devices include a first audio input device 201 and a second audio input device 202, where the number of audio output devices is 2, the number of audio input devices is 2, and the number of audio output devices just satisfies that each audio input device is assigned a complete audio output device, so that the first audio input device 201 can be assigned the first audio output device 140a, and the second audio input device 202 can be assigned the second audio output device 140b, so that audio data input by the first audio input device 201 can be played by all audio output channels of the first audio output device 140a, and audio data input by the second audio input device 202 can be played by all output channels of the second audio output device 140 b.

Illustratively, referring to fig. 7, the audio input device includes: the audio output devices include a first audio input device 201, a second audio input device 202 and a third audio input device 203, the audio output devices include a first audio output device 140a, a second audio output device 140b and a third audio output device 140c, the number of the audio output devices is 3, the number of the audio input devices is 3, and the number of the audio output devices just satisfies that each audio input device is allocated with a complete audio output device, so that the first audio input device 201 can be allocated with the first audio output device 140a, the second audio input device 202 is allocated with the second audio output device 140b, and the third audio input device 203 is allocated with the third audio output device 140c, so that the audio data input by the first audio input device 201 can be played by all audio output channels of the first audio output device 140a, and the audio data input by the second audio input device 202 can be played by all audio output channels of the second audio output device 140b The output channels are played, and the audio data inputted by the third audio input device 203 can be played by all the output channels of the second audio output apparatus 140 c.

Similarly, referring to fig. 8, when the number of the audio input devices is 4 and the number of the audio output devices is 4, one audio output device can be allocated to each audio input device, so that the audio data input by each audio input device is played by all the audio output channels of one audio output device.

Step S230: and if the second number is smaller than the first number, acquiring the number of the audio output channels of all the audio output devices as a third number.

In this embodiment, if the electronic device determines that the second number is smaller than the first number, the number of the audio output devices is not enough to allocate each audio input device to at least one complete audio output device. In this case, the electronic device may determine whether all audio output channels of at least one complete audio output apparatus can be assigned to a part of the audio input device, and then assign the audio output channels.

In some embodiments, the number of audio output channels per audio output device is the same, e.g., all 2, all 4, etc. The electronic apparatus may determine the number of audio output channels of all the audio output devices as the third number when it is judged that the second number is smaller than the first number. As one way, the electronic apparatus may acquire device information of each audio output device and then determine the number of audio output channels from the device information.

Step S240: obtaining a ratio of the third quantity to the first quantity.

Step S250: and if the ratio is larger than a set threshold value, distributing all audio output channels of at least one audio output device to part of the audio input devices.

In the embodiment of the present application, after acquiring the number of audio output channels of all audio output apparatuses, the electronic device may acquire a ratio between the third number of all audio output channels and the first number of all audio input apparatuses, so as to determine whether all audio output channels of at least one complete audio output apparatus may be allocated to a part of the audio input apparatuses according to the ratio. After the ratio is obtained, the electronic device may compare the ratio with a set threshold, where the set threshold is determined according to the number of audio output channels of the single audio output device. When the ratio is greater than the set threshold, the number of audio output channels is more, and all audio output channels of at least one complete audio output device can be distributed to at least part of audio input equipment; when the ratio is not greater than the set threshold, it means that there are fewer audio output channels, and if all audio output channels of at least one complete audio output device are allocated to at least some audio input devices, other audio input devices cannot be allocated to at least one audio output channel, or the audio output channels are allocated unevenly, resulting in uneven loudness of the audio input by each audio input device heard by the user, and poor experience.

In some embodiments, when the above ratio is greater than the set threshold, the electronic device allocates all audio output channels of at least one complete audio output apparatus to at least part of the audio input devices, the number of audio input devices to which the complete audio output apparatus can be allocated may be determined, and then the number of audio input devices is allocated to all audio output channels of at least one audio output apparatus, and it is ensured that the audio output apparatuses allocated to the audio input devices are different.

Optionally, each of the audio input devices of the number of audio input devices may allocate all audio output channels of one audio output apparatus, so as to avoid that the audio output channels allocated to the other audio input devices to which the complete audio output apparatus cannot be allocated are fewer, and that the sound loudness of the audio input by each audio input device heard by the user is uneven, which results in poor experience.

In some embodiments, the electronic device assigning all audio output channels of the at least one audio output apparatus to some of the plurality of audio input devices may include:

determining the number of audio input devices of the plurality of audio input devices that allocate all audio output channels of one audio output apparatus as a fourth number; acquiring the priority of each audio input device in the plurality of audio input devices; determining the fourth number of audio input devices from the plurality of audio input devices as the partial audio input devices based on the priority of each audio input device, wherein the partial audio input devices have a higher priority than the other audio input devices; all audio output channels of an audio output device are assigned to the part of the audio input apparatus.

In this embodiment, the electronic device assigns all audio output channels of one audio output apparatus to each of the partial audio input devices. After the electronic equipment determines the number of the audio input equipment capable of distributing complete audio output devices, the electronic equipment determines the number of the audio input equipment with relatively higher priority as the audio input equipment capable of distributing one audio output device according to the priority of the audio input equipment, and then distributes all audio output channels for audio output promotion to the audio input equipment. Therefore, the audio input equipment with relatively high priority can be distributed with a complete audio output device, and when the audio is played, the audio input equipment can be different from the audio input equipment input by other audio input equipment, so that the requirements of users can be better met, and the user experience is improved.

As an embodiment, the priority of the audio input device may be set according to the user's needs. For example, the electronic device may present an interface for setting the priority of the respective audio input devices for the user to set the priority of the respective audio input devices.

As another embodiment, the priority of the audio input device may be determined based on the type of audio input device. Illustratively, the audio input devices may be classified into: the priority of the audio input device is sequentially reduced according to the sequence of the desktop computer, the notebook computer, the tablet computer, the smart phone and the smart watch, and the above is only an example and does not represent the limitation on the actual priority.

In some embodiments, the electronic device determines the number of audio input devices of the plurality of audio input devices that allocate all audio output channels of an audio output apparatus, and may determine the number according to the above ratio. For example, the integer part of the ratio may be taken as the number, so that more audio input devices may be assigned to all audio output channels of one audio output apparatus; for another example, the value obtained by subtracting 1 from the integer part of the ratio may be used as the number, so that some audio input devices may be assigned to all audio output channels of one audio output apparatus, and the occurrence of uneven sound volume may be avoided.

In some embodiments, the above threshold setting is determined according to the number of audio output channels of a single audio output device, and since the number of audio output channels of each audio output device is the same, the threshold setting may be determined by the number of audio output channels of any one audio output device. For example, if the number of audio output channels of a single audio output device is 4, the set threshold may be 2. Of course, the specific determination mode for setting the threshold may not be limited.

For example, referring to fig. 9, the audio input device includes: the audio output devices include a first audio output device 140a and a second audio output device 140b, and the number of audio output channels of the first audio output device 140a and the second audio output device 140b is 4. At this time, the number of all audio output devices is 8, the number of audio input apparatuses is 3, and the ratio of the number of all audio output devices to the number of audio input apparatuses is greater than 2, so that the first audio input apparatus 201 may be assigned the first audio output device 140a, the second audio input apparatus 202 may be assigned the audio output channels b1 and b2 of the second audio output device 140b, and the third audio input apparatus 203 may be assigned the audio output channels b3 and b4 of the second audio output device.

Illustratively, referring to fig. 10, the audio input device includes: the audio output devices include a first audio output device 140a, a second audio output device 140b and a third audio output device 140c, and the number of audio output channels of the first audio output device 140a, the second audio output device 140b and the third audio output device 140c is 4. At this time, the number of all audio output devices is 12, the number of audio input apparatuses is 4, and the ratio of the number of all audio output devices to the number of audio input apparatuses is greater than 2, so that it is possible to allocate the first audio input apparatus 201 to the first audio output device 140a, allocate the second audio input apparatus 202 to the second audio output device 140b, allocate the third audio input apparatus 203 to the audio output channels c1 and c2 of the third audio output device 140c, and allocate the fourth audio input apparatus 204 to the audio output channels c3 and c4 of the third audio output device 140 c.

Step S260: at least one audio output channel of the remaining audio output means is assigned to each of the other audio input devices.

In this embodiment, after allocating all audio output channels of one audio output apparatus to the above part of the audio input apparatuses, the electronic device may allocate at least one audio output channel of the remaining audio output apparatuses to each of the other audio input apparatuses, where the other audio input apparatuses are the audio input apparatuses other than the part of the audio input apparatuses in the plurality of audio input apparatuses, and ensure that the audio output channels allocated to the different audio input apparatuses in the other audio input apparatuses are different.

Step S270: and if the ratio is less than or equal to a set threshold, allocating at least one audio output channel to each audio input device in the plurality of audio input devices.

In the embodiment of the present application, if the electronic device determines that the ratio is smaller than or equal to the set threshold, it indicates that none of the audio input devices can be assigned with all audio output channels of an audio output apparatus, so that at least one audio output channel can be assigned to each audio input device according to a principle that ensures that each audio input device is assigned with at least one audio output channel.

For example, referring to fig. 11, the audio input device includes: the audio output devices include a first audio output device 140a and a second audio output device 140b, and the number of audio output channels of the first audio output device 140a and the second audio output device 140b is 4. At this time, the number of all audio output apparatuses is 8, the number of audio input devices is 4, and the ratio of the number of all audio output apparatuses to the number of audio input devices is equal to 2, so that it is possible to allocate the audio output channels a1 and a2 of the first audio output apparatus 140a to the first audio input device 201, the audio output channels a3 and a4 of the first audio output apparatus 140a to the second audio input device 202, the audio output channels b1 and b2 of the second audio output apparatus 140b to the third audio input device 203, and the audio output channels b3 and b4 of the second audio output apparatus 140b to the fourth audio input device 204.

In some embodiments, since the above is performed based on the case that the number of audio output channels of each audio output device is the same when the second number is smaller than the first number, the electronic apparatus may further determine whether the number of audio output channels of each audio output device is the same before performing the step S230 to acquire the number of audio output channels of all audio output devices, and perform the acquisition of the number of audio output channels of all audio output devices when the number is the same; if the audio input devices are different, the audio output channels can be allocated to the audio input devices according to the principle that all the audio output channels of one audio output device are allocated to some audio input devices as much as possible.

In the embodiment of the present application, step S280 and step S290 may refer to the contents of the foregoing embodiments, and are not described herein again.

In some embodiments, the electronic device may have no external audio output apparatus, and in this case, the electronic device may have only one audio output apparatus, and in this case, the at least one audio output channel may be allocated to the audio input devices according to a principle that ensures that the at least one audio output channel is allocated to each audio input device. Illustratively, referring to fig. 12, the audio input device includes: first audio input device 201 and second audio input device 202, the audio output means comprising first audio output device 140a, in which case the audio output channels a1 and a2 of first audio output device 140a may be assigned to first audio input device 201, and the audio output channels a3 and a4 of first audio output device 140a may be assigned to second audio input device 202.

Similarly, the electronic device may allocate all audio output channels of one audio output device to the audio input device as far as possible according to the principle of preferentially allocating the entire audio output device to the audio input device; when the number of the audio output devices cannot guarantee that all audio output channels of one audio output device can be allocated to the audio input devices, different channels of the audio output devices are allocated to different audio input devices, and it is guaranteed that the audio output channels allocated to each audio input device are different, so that at least part of audio data of the audio input devices can be played by the complete audio output devices (namely all channels of the audio output devices are used for playing the audio data of one audio input device), and a user can conveniently distinguish playing sounds corresponding to the audio data of different audio input devices. Besides, when the electronic device allocates the audio output channel, the audio output channel allocated to the audio input device can be made to be close to the audio input device according to the above relative position relationship, for example, if the audio input device 1 is located on the left side of the electronic device, the audio output channel on the left side can be allocated to the audio input device 1; the audio input device 2 is located on the right side of the electronic device, and the right audio output channel may be assigned to the audio input device 2.

In some embodiments, the electronic device may allocate, according to the first number and the second number, a corresponding number of audio output channels to each audio input device, and then allocate, according to a relative position relationship between the audio input device and the electronic device and a position of the audio output channels, a corresponding number of audio output channels to the audio input device.

In this embodiment, the electronic device may divide the display interface into a plurality of regions based on the number of resources to be displayed of the plurality of audio input devices, and then correspond each of the plurality of regions to one video, thereby generating a display layout of the resources to be displayed of each audio input device in the display interface. The ratio of the sum of the areas occupied by the resources to be displayed of the plurality of audio input devices in the display interface to the area of the display interface can be the largest. The positions and the sizes of the resources to be displayed of the audio input devices in the display interface are arranged in the layout mode, so that the proportion of the resources to be displayed of the audio input devices in the display interface can be the largest, and the area in the display interface can be fully utilized.

In other embodiments, the electronic device may also generate the display layout based on display parameters of resources to be displayed of the plurality of audio input devices in their corresponding audio input devices. Similarly, the ratio of the sum of the areas occupied by the resources to be displayed of the plurality of audio input devices in the display interface to the area of the display interface can be maximized.

In addition, the electronic device can acquire the size information of the video, that is, the electronic device can acquire the size information of the video, such as "length", "width", "aspect ratio", "area", and the like.

In still other embodiments, the electronic device may also obtain a relative positional relationship between the electronic device and the audio input device corresponding to the resource to be displayed of each audio input device, and then determine the display layout based on the relative positional relationship. Wherein the relative positional relationship may be used to characterize the relative distance and relative angle of the audio input device and the electronic device.

Similarly, the electronic device may allocate all audio output channels of one audio output device to the audio input device as far as possible according to the principle of preferentially allocating the entire audio output device to the audio input device; when the number of the audio output devices cannot guarantee that all audio output channels of one audio output device can be allocated to the audio input devices, different channels of the audio output devices are allocated to different audio input devices, and it is guaranteed that the audio output channels allocated to each audio input device are different, so that at least part of audio data of the audio input devices can be played by the complete audio output devices (namely all channels of the audio output devices are used for playing the audio data of one audio input device), and a user can conveniently distinguish playing sounds corresponding to the audio data of different audio input devices. In addition, the electronic device may enable the audio output channel allocated to the audio input device to be close to the display position of the resource to be displayed of the audio input device according to the above display layout when the audio output channel is allocated.
