and distributing a first channel audio signal to the first electronic device and distributing a second channel audio signal to the N second electronic devices according to the corresponding relation between the J electronic devices and the M channel audio signals.

Specifically, when channel audio signals are allocated to each of the J electronic devices, the correspondence between the J electronic devices and the M channel audio signals may be determined according to the positions of the N second electronic devices relative to the first electronic device and the position of the first electronic device. And then distributing a first channel audio signal for the first electronic device, distributing a second channel audio signal for the N second electronic devices, and sending the second channel audio signal to the second electronic devices.

if a third target electronic device is closest to a fourth target electronic device of the M electronic devices, determining a channel audio signal corresponding to the fourth target electronic device as a channel audio signal corresponding to the third target electronic device, where the third target electronic device is an electronic device of the J electronic devices except the M electronic devices;

Determining a correspondence between the M electronic devices of the J electronic devices and the M channel audio signals, and a correspondence between the channel audio signals of the third target electronic device and the fourth target electronic device, as a correspondence between the J electronic devices and the M channel audio signals.

That is, M electronic devices are selected from the J electronic devices according to the position of the second electronic device relative to the first electronic device and the position of the first electronic device, and the correspondence relationship between the M electronic devices and the M channel audio signals is determined, for example, if M is 4, the first electronic device determines 4 electronic devices having the positional relationship of front left, rear left, front right, and rear right among the J electronic devices, allocates the front left channel to the electronic device located at the front left position, allocates the front right channel to the electronic device located at the front right position, allocates the rear left channel to the electronic device located at the rear left position, and allocates the rear right channel to the electronic device located at the rear right position.

Then, the channel audio signals are assigned to the electronic apparatuses other than the M electronic apparatuses among the J electronic apparatuses. Namely: if a third target electronic device is closest to a fourth target electronic device of the M electronic devices, determining a channel audio signal corresponding to the fourth target electronic device as a channel audio signal corresponding to the third target electronic device, where the third target electronic device is an electronic device of the J electronic devices except the M electronic devices. For example, if the third target electronic device is closest to the electronic device located at the front left position, the channel audio signal corresponding to the third target electronic device is the front left channel audio signal. Therefore, the same audio signal can be played by the loudspeaker of the electronic equipment closest to the loudspeaker, the interference on the spatial sense caused by the fact that the electronic equipment playing the same audio signal is too far away is avoided, and the playing effect of the target audio file is improved.

Furthermore, the electronic device assigned to one channel cannot be more than half of J, and if more than J is assigned, the channel assigned to the electronic device closest to the second electronic device is assigned to the electronic device.

For another example, if J is smaller than M, determining a correspondence relationship between J electronic devices and J channel audio signals in the M channel audio signals according to a position of each electronic device in the N second electronic devices relative to the first electronic device and a position of the first electronic device; for channel audio signals other than J channel audio signals in the M channel audio signals, the channel audio signals may be respectively allocated to one or more of the J electronic devices in a random allocation manner, or may be allocated according to a positional relationship of the J electronic devices, which is not limited herein.

and playing the target audio file by using the loudspeakers of the U pieces of electronic equipment.

Specifically, in the process of playing the target audio file, the electronic device that plays the target audio file may be adjusted, for example, a new electronic device is added and/or an existing electronic device is deleted. As shown in fig. 2d, a user may click on the edit in the upper right corner of the device control page in fig. 2d to generate an edit interface, and as shown in fig. 2e, the user may delete and add devices through the edit interface, where the edit interface includes the identifier of the first electronic device and the identifiers of the P electronic devices. The second input is an input for displaying an editing interface, the third input is an input for adding or deleting electronic devices, and U electronic devices can be determined according to the third input, and can comprise the first electronic device or not. And then, playing the part of the target audio file which is not played completely by utilizing the U electronic equipment.

In this embodiment, the played electronic device can be adjusted in the playing process of the target audio file, and then the adjusted electronic device is used to continue playing the target audio file, so that more playing choices are provided for a user, and the interest of playing the target audio file is enhanced.

Specifically, the U electronic devices include electronic devices in the J electronic devices, and the channel audio signals allocated to each of the U electronic devices are not changed and are still the channel audio signals allocated before the number of the electronic devices is adjusted. However, since the number of the electronic devices is reduced, the channel audio signal of the removed electronic device (i.e., the sixth target electronic device) is not allocated to the corresponding electronic device, and then the fifth target electronic device of the U electronic devices needs to play the audio corresponding to the channel audio signal allocated to the sixth target electronic device, so that the speaker of the fifth target electronic device needs to play the audio corresponding to the multiple channel audio signals. And the fifth target electronic device is the device closest to the sixth target electronic device in the U electronic devices.

For the electronic device whose channel audio signal does not change among the U electronic devices, the audio corresponding to the channel audio signal corresponding to the electronic device is still played, and for the fifth target electronic device, the audio corresponding to the channel audio signal allocated to the sixth target electronic device is also played.

The channel audio signal corresponding to the fifth target electronic device cannot be more than half of M, and if so, the channel audio signal allocated to the sixth target electronic device is allocated to the electronic device which is the second closest to the sixth target electronic device.
