Fig. 1 shows a flowchart of a method for multi-channel playback applied to a control device according to an embodiment of the present application, the method including step S11, step S12, step S13, and step S14. In step S11, the control apparatus determines a plurality of user apparatuses participating in multi-channel play in the current environment; in step S12, the control device obtains location information corresponding to each of a plurality of user devices participating in multi-channel playing in the current environment; in step S13, the control device determines audio information to be played by the plurality of user devices, and determines channel information corresponding to each user device from a plurality of channel information corresponding to the audio information according to the location information corresponding to each user device; in step S14, the control device sends the audio information and the channel information corresponding to the user device, so that the audio information is played simultaneously on each user device according to the respective channel information.

In step S11, the control device determines a plurality of user devices participating in multi-channel playback in the current environment. In some embodiments, the current environment may be an indoor environment or an outdoor environment. In some embodiments, the control device may be one of a plurality of user devices participating in multi-channel playback, or may be another user device not participating in multi-channel playback, or may be a network device. In some embodiments, a plurality of candidate user equipments in the current environment are obtained, and a plurality of user equipments participating in multi-channel playing are determined from the plurality of candidate user equipments, for example, a location area corresponding to the current environment may be obtained first, then all user equipments currently in the location area are taken as candidate user equipments, and then the plurality of user equipments participating in multi-channel playing are determined from the plurality of candidate user equipments.

In step S12, the control device acquires location information corresponding to each of the plurality of user devices. In some embodiments, each user device participating in multi-channel playing in the current environment acquires its own position information in the current environment through its own sensor module (e.g., an acceleration sensor, a magnetic sensor, an orientation sensor, a gyroscope, etc.), and transmits the position information to the control device, wherein the position information includes, but is not limited to, position coordinate related information of the user device in the current environment, current attitude information of the user device, current orientation information of the user device, and the like. In some embodiments, data is transmitted between the control device and a plurality of user devices participating in multi-channel playback over an established wireless communication connection, e.g., bluetooth, WiFi, 4G, 5G, etc.

In step S13, the control device determines audio information to be played by the plurality of user devices, and determines channel information corresponding to each user device from the plurality of channel information corresponding to the audio information according to the location information corresponding to each user device. In some embodiments, when the control device is a user device participating in multi-channel playing or a user device not participating in multi-channel playing, the audio information may be determined by a user corresponding to the control device, and when the control device is a network device, the audio information may be sent to the network device after the user initiating the multi-channel playing activity or the user determining the multi-channel playing activity. In some embodiments, the audio information may include the audio file itself, or may include identification information (e.g., a link address, etc.) corresponding to the audio file, from which the audio file may be obtained, or may include other related information (e.g., soundtrack information, etc.) corresponding to the audio file. In some embodiments, the channel information is identification information (e.g., channel track name, etc.) corresponding to a channel track in an audio file to which the audio information corresponds, the audio file including a plurality of channel tracks, e.g., a front left surround channel track, a front right surround channel track, a center surround channel track, a rear left surround channel track, a rear right surround channel track, a left surround channel track, a right surround channel track, etc. In some embodiments, a channel track that matches the location information of each device is determined from a plurality of channel tracks corresponding to the audio file based on the location information of each device in the current environment, for example, the location information of the user device D1 is the front left of the current environment, the plurality of channel tracks corresponding to the audio file includes a front left surround channel track, a front right surround channel track, and a center surround channel track, and the channel track that matches the location information of the user device D1 is the front left surround channel track. In some embodiments, for each of a plurality of channel tracks corresponding to an audio file, the channel track is respectively matched with the position information of each user equipment participating in multi-channel playing, at least one user equipment with which the degree of matching between the channel tracks meets a predetermined degree of matching threshold may be determined as a user equipment matched with the channel track, or a predetermined number of user equipments with which the degree of matching between the channel tracks is higher may be determined as user equipments matched with the channel track. In some embodiments, for each user device participating in multi-channel playing, the location information of the user device is respectively matched with each channel track corresponding to an audio file, at least one channel track having a matching degree with the location information of the user device satisfying a predetermined matching degree threshold may be determined as a channel track matched with the user device, or a predetermined number of channel tracks having a higher matching degree with the location information of the user device may be determined as channel tracks matched with the user device. In some embodiments, if only one channel track matched with a certain user equipment participating in multi-channel playing exists in the user equipment, the channel track is directly used as the channel track corresponding to the user equipment. In some embodiments, if a plurality of channel tracks matching with a user equipment exists in the user equipment participating in multi-channel playing, a channel track with the highest matching degree is determined from the plurality of channel tracks as a channel track corresponding to the user equipment.

In step S14, the control device sends the audio information and the channel information corresponding to the user device, so that the audio information is played simultaneously on each user device according to the respective channel information. In some embodiments, for each user equipment, the audio information and the channel information corresponding to the user equipment are sent to the user equipment, and then after receiving the audio information and the respective channel information, the plurality of user equipment simultaneously play the audio information according to the respective corresponding channel information. In some embodiments, the audio information and the respective channel information may be sent to each user device together, or the audio information and the respective channel information may be sent to each user device separately. In some embodiments, if a user equipment participating in multi-channel playing does not have a channel track matching with the position information thereof, the audio information is not sent to the user equipment, and the user equipment does not participate in multi-channel playing, or a prompt message for prompting that a channel track matching with the position information of the user equipment does not exist and that the user equipment does not participate in multi-channel playing is sent to the user equipment and presented, or rough position information matching with a vacant channel track of the user equipment which does not currently exist in the audio information is sent to the user equipment and presented, so as to prompt that a user corresponding to the user equipment can move to a rough position range indicated by the rough position information, when the latest position information after the user equipment moves has a channel track matching therewith, at this time, the audio information and the channel information matched with the latest position information may be transmitted to the user equipment, or a prompt message for prompting the user to stop moving may be transmitted to the user equipment and presented. In some embodiments, when the control device is a user device participating in multi-channel playing or a user device not participating in multi-channel playing, in response to a play trigger operation performed on the control device by a user corresponding to the control device for audio information, a play instruction is generated and sent to each user device participating in multi-channel playing, so as to uniformly control each user device to simultaneously start playing an audio file. In some embodiments, when the control device is a network device, in response to a play trigger operation performed on the user device by an initiating user of multi-channel play or a control user for audio information, a play instruction is generated and sent to the network device, so as to send the play instruction to each user device participating in multi-channel play through the network device, so as to uniformly control each user device to simultaneously start playing an audio file. In some embodiments, the playback instructions include, but are not limited to, start playback time information, playback volume information, looping mode information, audio playback start point information, and the like.

In some embodiments, when the control device is a user device participating in multi-channel playing or a user device not participating in multi-channel playing, the control device may present device-related information of a plurality of candidate user devices and user-related information of a candidate user corresponding to each candidate user device on the device, and in response to a selection operation performed by a user corresponding to the control device for the plurality of candidate user devices, take the candidate user device selected by the user as the plurality of user devices determined to participate in multi-channel playing, or, when the control device is a network device, the control device may send and present the acquired device-related information of the plurality of candidate user devices and the user-related information of the candidate user corresponding to each candidate user device to an initiating user of multi-channel playing or a user device corresponding to the control user, and then the initiating user or the control user performs the selection operation for the plurality of candidate user devices, the corresponding user equipment sends the identification information of a plurality of candidate user equipment selected by the initiating user or the control user or the identification information of a plurality of candidate users to the network equipment, and after the network equipment receives the plurality of identification information, the candidate user equipment identified by the plurality of identification information is used as a plurality of user equipment which is determined to participate in the multi-channel playing.

In some embodiments, the step S16 includes: the control device responds to selection operation performed by a user for the candidate user devices, sends request information for requesting the target user devices to participate in multi-channel playing to a plurality of target user devices selected by the user from the candidate user devices, receives feedback information corresponding to the request information sent by at least one target user device from the target user devices, and determines the user devices participating in multi-channel playing according to the feedback information of the target user devices. In some embodiments, the control device sends request information for requesting each target user device to participate in the multi-channel playing to a plurality of target user devices selected from the plurality of candidate user devices by a user in response to selection operations performed by the user on the plurality of candidate user devices, then each target user device generates feedback information according to feedback operations performed by the user (for example, approving to participate in the multi-channel playing or rejecting to participate in the multi-channel playing) after receiving and presenting the request information, and returns the feedback information to the control device, and the control device determines the target user device which has fed back the approval as the plurality of user devices participating in the multi-channel playing according to the feedback information returned by each target user device. In some embodiments, the feedback operation has a deadline, and after the deadline is reached, the target user corresponding to the target user equipment may not perform the feedback operation on the request information any more, or may not retransmit the feedback information to the control equipment, or the control equipment may not process the received feedback information any more, and the target user equipment that is not currently fed back within the deadline may be determined as agreeing to participate in the multi-channel playing by default, or determined as refusing to participate in the multi-channel playing by default.

In some embodiments, the step S14 includes a step S17 (not shown). In step S17, the control device receives request information for requesting participation in multi-channel playing, which is sent by a plurality of candidate user devices in the current environment, and determines the candidate user devices as the plurality of user devices participating in multi-channel playing. In some embodiments, a plurality of candidate user devices in the current environment actively send request information requesting participation in multi-channel playing to the control device, and the control device determines the candidate user devices as the user devices participating in multi-channel playing after receiving the request information sent by the candidate user devices. In some embodiments, the candidate user device sends its own location information to the control device at the same time as sending the request information to the control device.

In some embodiments, the request information includes password information; wherein the determining of the plurality of candidate user equipments as the plurality of user equipments participating in the multi-channel playing comprises step S18 (not shown). In step S18, the control device checks the password information in the request information corresponding to each of the candidate user devices, and determines the candidate user device as a user device participating in multi-channel playing if the check is passed. In some embodiments, the request information sent by the candidate user device to the control device includes password information, when the control device is a user device participating in multi-channel playing or a user device not participating in multi-channel playing, the control device detects whether the password information in the request information is consistent with the password information set by the user corresponding to the control device after receiving the request information, if so, the check is passed, otherwise, the check is not passed, when the control device is a network device, the initiating user or the control user of multi-channel playing sets the password information of the multi-channel playing activity on the user device and sends the password information to the network device, the network device detects whether there is multi-channel playing activity corresponding to the password information in the request information after receiving the request information sent by the candidate user device, and if so, the check is passed, otherwise the check fails.

In some embodiments, the request information sent by the candidate user equipment to the control equipment includes password information and position information of the candidate user equipment, when the control equipment is user equipment participating in multi-channel playing or user equipment not participating in multi-channel playing, the control equipment detects whether the password information is consistent with the password information set by a user corresponding to the control equipment after receiving the request information, if so, continuously judges whether the position information of the candidate user equipment meets a multi-channel playing position condition, for example, whether the position of the candidate user equipment in the current environment is less than or equal to the farthest position range of the multi-channel playing activity, or whether the distance between the position of the candidate user equipment and the positions of other candidate user equipment in the current environment is greater than or equal to the minimum distance interval of the multi-channel playing activity, when the control device is a network device, the network device detects whether multichannel playing activity corresponding to the password information in the request information exists after receiving the request information sent by the candidate user device, and if the multichannel playing activity exists, the network device continuously judges whether the position information of the candidate user device meets multichannel playing position conditions.

In some embodiments, the determining, according to the location information corresponding to each user device, channel information corresponding to each user device from a plurality of channel information corresponding to the audio information includes: determining the relative position information of each user device relative to the audio listening position according to the position information corresponding to each user device, wherein the relative position information comprises direction information; and determining the channel information corresponding to each user device from a plurality of channel information corresponding to the audio information according to the relative position information. In some embodiments, the audio listening position may be a position of the control device when the control device is a user device participating in multi-channel playing or a user device not participating in multi-channel playing, and the audio listening position may be a position of a user device corresponding to an initiating user or a control user of multi-channel playing when the control device is a network device. In some embodiments, the audio listening position may also be any position in the current environment, preferably the audio listening position is a central position corresponding to a plurality of user equipments participating in the multi-channel playing. In some embodiments, the relative position information of each user device with respect to the audio listening position may be determined based on the position information of each user device and the position information of the audio listening position, the relative position information including, but not limited to, direction information of the user device with respect to the audio listening position, the user device of a certain direction being adapted to play a channel track matching the direction, the user device of a different direction being adapted to play a different channel track of an audio file, for example, the user device D1 relative position information is "D1 at the front left of the control device D0", the plurality of channel tracks corresponding to the audio file includes a front left surround channel track, a front right surround channel track, a center surround channel track, and the channel track corresponding to the user device D1 is determined from the plurality of channel information as the front left surround channel track.

In some embodiments, the audio listening position is a position of the control device. In some embodiments, the audio listening position may be a position of the control device when the control device is a user device participating in multi-channel playing or a user device not participating in multi-channel playing, and the audio listening position may be a position of a user device corresponding to an initiating user or a control user of multi-channel playing when the control device is a network device.

In some embodiments, the audio listening position is a central position corresponding to the plurality of user devices; wherein the method further comprises: and determining the central positions corresponding to the user equipment according to the position information corresponding to each user equipment. In some embodiments, a center point of a plurality of user devices participating in multi-channel playing in a current environment is determined according to a location of each of the plurality of user devices, and the location of the center point is used as a center location corresponding to the plurality of user devices.

In some embodiments, the relative position information further includes distance information of the user devices relative to the audio listening position, from which corresponding playback volume information may be determined at the time the audio information is played back on each of the user devices. In some embodiments, the playback volume information is positively correlated with the distance information, the farther the user equipment is from the audio listening position, the greater the playback volume, and the closer the user equipment is from the audio listening position, the smaller the playback volume. In some embodiments, for each user device, the playback volume information corresponding to the user device may be sent to the user device together with the channel information, or the playback volume information corresponding to the user device may be separately developed from the channel information to the user device. In some embodiments, each user device simultaneously plays audio information according to the received respective corresponding playback volume information and channel information.

In some embodiments, the method further comprises: acquiring position change information of the audio listening position, and re-determining the relative position information of each user equipment relative to the audio listening position according to the position change information; determining the latest sound channel information corresponding to the audio information when the audio information is played on each user device according to the re-determined relative position information; and for each user device, sending the latest sound channel information corresponding to the user device, so as to adjust the user device according to the respective latest sound channel information and continuously play the audio information. In some embodiments, during the playing of the audio file, the position change information of the audio listening position is obtained in real time, for example, the position change information may be the direction change information and the distance change information of the current audio listening position relative to the historical audio listening position, for example, the position change information may be that the audio listening position moves 1 meter to the left front, or the audio listening position rotates 45 degrees to the clockwise direction. In some embodiments, when the control device is a user device participating in multi-channel playing or a user device not participating in multi-channel playing, the change in the audio listening position may be caused by a position movement of the control device, and when the control device is a network device, the change in the audio listening position may be caused by a position movement of an initiating user of multi-channel playing or a user device corresponding to the controlling user. In some embodiments, the change in audio listening position may also be caused by a position movement of at least one of the plurality of user devices participating in the multi-channel playback. In some embodiments, it is desirable to detect whether the location change information satisfies a predetermined location change threshold, and if so, to re-determine the relative location information of each user device with respect to the audio listening position, for example, whether the distance change of the audio listening position is greater than or equal to a predetermined distance threshold, or whether the direction change of the audio listening position is greater than or equal to a predetermined angle threshold. In some embodiments, after the relative position information of each user device with respect to the audio listening position is re-determined, the corresponding latest channel information when the audio information being played is played on each user device is re-determined, and then the latest channel information corresponding to each user device is sent to the user device, so as to adjust and simultaneously continue to play the audio information on each user device according to the respective latest channel information. In some embodiments, the latest playing volume information corresponding to the audio information being played when the audio information is played on each user device is also determined again according to the re-determined relative position information of each user device with respect to the audio listening position, and then the latest playing volume information corresponding to each user device is sent to the user device, so that the volume adjustment is performed on each user device according to the respective latest playing volume information.
