All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the embodiments and drawings of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The embodiment of the invention discloses a playing control method and device for multiple sound boxes, which can reduce interference noise generated among different sound boxes when the multiple sound boxes are in a playing state at the same time, and further reduce the influence of the interference noise on the user experience. The following are detailed below.

Example one

Referring to fig. 1, fig. 1 is a flow chart illustrating a playing control method for multiple audio boxes according to an embodiment of the present invention. As shown in fig. 1, the playing control method for multiple speakers may include the following steps:

101. when the first sound box is in a playing state, the control device detects whether at least one second sound box in the playing state exists, and if the second sound box exists, the step 102 is executed; if it is detected that the second speaker is not present, the process continues to step 101.

In an embodiment of the present invention, the first sound box and the second sound box may be in direct communication, or the first sound box and the second sound box may not be in direct communication, but the control device realizes communication interaction between them, which is not limited in the embodiment of the present invention. That is, the control device may be applied to each speaker device, or may be applied to a terminal device such as a mobile phone or a tablet, and is used to control the speaker to perform operations such as playing, and to implement communication interaction between different speakers.

It should be noted that the number of the second sound boxes may be one or multiple, and the embodiment of the present invention is not limited.

102. And the control device acquires the volume value of the sound recorded by the first loudspeaker box according to the content played by each second loudspeaker box to obtain a volume value set.

In the embodiment of the present invention, since the number of the second speakers may be one or more, the control device may form the volume value set by the volume values of the sounds recorded by the first speakers.

In the embodiment of the present invention, the volume values of different second sound boxes during sound playing are different, and because there is attenuation in the sound propagation process, the control device needs to collect the volume values of the sound recorded by the first sound box for the content played by each second sound box, so as to obtain a volume value set. This is favorable to improving the accuracy of judging whether the second audio amplifier causes interference to the first audio amplifier.

103. The control device judges whether a target volume value which is greater than or equal to a preset volume value threshold exists in the volume value set, if so, the step 104 is executed; if the judgment result is negative, the flow is ended.

In the embodiment of the present invention, the preset volume value threshold is a minimum volume value that causes interference to the content played by the first speaker.

As an optional implementation manner, after determining that there is a target volume value greater than or equal to a preset volume value threshold in the volume value set, the control device may further perform the following operations:

sending an environment detection instruction to a target second sound box corresponding to the target volume value in all the second sound boxes so that the target second sound box obtains an environment image of an environment area where the target second sound box is located according to the environment detection instruction and returns the environment image;

and judging whether the environment image contains people or not, and if so, executing step 104.

In an embodiment of the present invention, the target second sound box receives an environment detection instruction sent by the control device, detects whether an associable image capturing device exists within a preset area after receiving the environment detection instruction, sends a communication connection request to the image capturing device to establish a communication connection with the image capturing device if the associable image capturing device is detected, sends an environment image capturing request to the image capturing device to capture the environment image, and sends the environment image to the control device. Analyzing the environment image by the control device, extracting characteristic parameters of the environment image, judging whether the environment image contains people according to the characteristic parameters, and if the environment image contains people, knowing that the user uses the target second sound box, thus triggering to execute step 104; if the environment image is judged to contain no person, the user can know that the target second sound box is not used by the user currently, therefore, a play pause instruction is sent to the target second sound box, the content played by the target second sound box currently is cached, and the user of the target second sound box can immediately use the target second sound box to play when returning to the environment area where the target second sound box is located again. Therefore, by implementing the embodiment of the invention, whether the environment area where the current target second sound box is located is occupied can be judged through the environment image, and the playing of the target second sound box is paused in time when the situation that no people exist is judged, so that on one hand, the power consumption of the target second sound box can be reduced, and the waste of the electric quantity of the sound box is reduced; on the other hand, the generation of interference noise can be avoided from the source, and the use experience of the user is further improved.

104. And the control device sends a volume adjusting instruction to a target second sound box corresponding to the target volume value in all the second sound boxes so as to trigger the target second sound box to reduce the playing volume of the target second sound box according to the volume adjusting instruction.

In the embodiment of the present invention, the control device may send a uniform volume adjustment instruction to the target second sound boxes corresponding to the target volume values among all the second sound boxes, or may send different volume adjustment instructions according to the obtained actual situation information of different target second sound boxes in a targeted manner. The actual situation information may include, but is not limited to, spatial position information of the target second sound box, area information of an environment area where the target second sound box is located, person detection information used for indicating whether a person exists around the second sound box, and the like.

As an optional implementation manner, after detecting that the second sound box exists in step 101, the control device may obtain first content of the first sound box and second content of the second sound box, obtain a second content set according to all the second content, determine whether a target second content different from the first content exists in the second content set, if so, collect a volume value of sound recorded by the first sound box for the target second content to obtain a volume value set, and then execute steps 103 to 104; further, after it is determined that there is no target second content different from the first content, a second playing progress of the target second content is further obtained to obtain a second playing progress set, and it is determined whether there is a target second playing progress in the second playing progress set that is asynchronous with the first playing progress of the first content, if so, a volume adjustment instruction is sent to a target second sound box corresponding to the target second playing progress to trigger the target second sound box to reduce its playing volume according to the volume adjustment instruction.

Therefore, by the method described in fig. 1, when a plurality of speakers are in a playing state at the same time, interference noise generated between different speakers can be reduced, thereby reducing the influence of the interference noise on the user experience; whether the environment area where the current target second sound box is located is someone can be judged through the environment image, and the playing of the target second sound box is paused in time when no person is judged, so that the power consumption of the target second sound box can be reduced, the waste of the electric quantity of the sound box is reduced, the generation of interference noise can be avoided from the source, and the use experience of a user is further improved.

Example two

Referring to fig. 2, fig. 2 is a schematic flow chart of another playing control method for multiple speakers according to an embodiment of the present invention. As shown in fig. 2, the playing control method of the multi-sound box may include the following steps:

in the embodiment of the present invention, the method for controlling the playing of multiple sound boxes includes steps 201 to 203, and for the description of steps 201 to 203, please refer to the detailed description of steps 101 to 103 in the first embodiment, which is not repeated herein. If the judgment result in step 203 is yes, step 204 is triggered to be executed, and if the judgment result in step 203 is no, the present process is ended.

204. The control device acquires first playing content of the first sound box and second playing content of the target second sound box corresponding to the target volume value.

205. The control device judges whether the first playing content is the same as the second playing content, and executes the steps 206-207 when the first playing content is the same as the second playing content; when the first playing content is not the same as the second playing content, step 208 is executed.

In the embodiment of the present invention, the way for the control device to determine whether the first playing content is the same as the second playing content may specifically be:

judging whether the playing types of the first sound box and the target second sound box are the same, wherein the playing types can include broadcasting and non-broadcasting (including music, English listening and the like);

if the playing types are different, determining that the first playing content is different from the second playing content, and executing step 208;

if the playing types are the same, when the playing types are broadcasting, judging whether the broadcasting frequency bands (broadcasting channels) of the first sound box and the target second sound box are the same, if the broadcasting frequency bands are the same, determining that the first playing content is the same as the second playing content, and executing the steps 206-207; if the broadcast frequency bands are different, determining that the first broadcast content is different from the second broadcast content, and performing step 208;

if the playing types are the same, when the playing types are non-broadcast, extracting first semantic information of the first playing content and second semantic information of the second playing content, judging whether the first semantic information and the second semantic information are completely the same, if so, determining that the first playing content is the same as the second playing content, and executing the steps 206-207; if not, it is determined that the first playing content is not the same as the second playing content, and step 208 is performed.

It should be noted that the above embodiment may be applied to the case that the number of the target second sound boxes is one, and particularly, when the number of the target second sound boxes is at least two, the control device determines whether the first playing content is the same as the second playing content, and when the first playing content is the same as the second playing content, it indicates that the second playing content of all the target second sound boxes is the same as the first playing content, so that the execution of steps 206 to 207 may be triggered; when the first playing content is different from the second playing content, it indicates that the second playing content of at least one target second sound box in the plurality of target second sound boxes is different from the first playing content, so that the step 208 can be triggered and executed, that is, a volume adjusting instruction is sent to all target second sound boxes to trigger all target second sound boxes to reduce the playing volume of the target second sound boxes according to the volume adjusting instruction; or directly sending a volume adjustment instruction to the target second sound boxes to be processed, which have different second playing contents from the first playing contents, of all the target second sound boxes, and executing steps 206 to 207 on the remaining target second sound boxes except the target second sound boxes to be processed, of all the target second sound boxes.

In the embodiment of the present invention, optionally, after determining that the first playing content is different from the second playing content, the control device may push the first playing content to the second sound box, so as to improve the interest of the interaction between the devices.

206. The control device acquires a first playing progress of the first sound box aiming at the first playing content and acquires a second playing progress of the target second sound box aiming at the second playing content.

207. The control device judges whether the first playing progress is the same as the second playing progress, and if the first playing progress is not the same as the second playing progress, step 208 is executed; when the first playing progress is the same as the second playing progress, the process is ended.

In the embodiment of the invention, when more than or equal to two sound boxes play simultaneously, even if the playing contents are the same, the playing progress of the contents is asynchronous, so that the playing of the contents is interfered. Therefore, in the implementation of the present invention, it can be further determined whether the playing of the target second sound box interferes with the current playing of the first sound box by determining the playing schedules of the first sound box and the target second sound box, and when it is determined that the first playing schedule of the first sound box is different from the second playing schedule of the target second sound box, step 208 is executed to reduce the interference of the target second sound box with the playing of the first sound box.

As an optional implementation manner, after determining that the first playing progress is different from the second playing progress, the playing control device may obtain a working mode of the target second sound box, where the working mode may include an omnidirectional playing working mode and/or a directional playing working mode. When the working mode of the target second sound box is detected to comprise the directional play working mode, a working mode changing instruction can be sent to the target second sound box, and the working mode changing instruction can comprise a target changing direction and a target changing volume. The target second sound box can change the current playing direction into a target changing direction according to the working mode changing instruction and change the current playing volume into the target changing volume. Further optionally, the target change direction is a play direction away from the first sound box, and the target change volume is a volume value lower than the play volume of the first sound box. Therefore, according to the embodiment of the invention, the working mode of the target second sound box can be changed, so that the target second sound box plays the second playing content in the preset volume and direction, the influence of the playing of the target second sound box on the playing quality of the first sound box is reduced, and the interference generated between a plurality of sound boxes during the simultaneous playing is reduced.

208. And the control device sends a volume adjusting instruction to a target second sound box corresponding to the target volume value in all the second sound boxes so as to trigger the target second sound box to reduce the playing volume of the target second sound box according to the volume adjusting instruction.

Therefore, by the method described in fig. 2, when a plurality of speakers are in a playing state at the same time, interference noise generated between different speakers can be reduced, thereby reducing the influence of the interference noise on the user experience; whether a person exists in the environment area where the current target second sound box is located can be judged through the environment image, and the playing of the target second sound box is paused in time when the absence of the person is judged, so that the power consumption of the target second sound box can be reduced, the waste of the electric quantity of the sound box is reduced, the generation of interference noise can be avoided from the source, and the use experience of a user is further improved; in addition, the working mode of the target second loudspeaker box can be changed, so that the target second loudspeaker box plays second playing contents in preset volume and direction, the influence of the playing of the target second loudspeaker box on the playing quality of the first loudspeaker box is reduced, and the interference generated between a plurality of loudspeaker boxes during the simultaneous playing is reduced.

EXAMPLE III

Referring to fig. 3, fig. 3 is a schematic flow chart of another playing control method for multiple speakers according to an embodiment of the present invention. As shown in fig. 3, the playing control method of the multi-sound box may include the following steps:

in the embodiment of the present invention, the method for controlling the playing of multiple sound boxes includes steps 301 to 307, and for the description of steps 301 to 307, please refer to the detailed description of steps 201 to 207 in the first embodiment, which is not repeated herein. If the determination result in the step 307 is no, the step 308 is triggered to be executed, and if the determination result in the step 307 is yes, the current process is ended.

308. The control device obtains a first priority of the first loudspeaker box and a second priority of the target second loudspeaker box corresponding to the target volume value.

309. The control device judges whether the first priority is higher than the second priority, and if the first priority is higher than the second priority, the steps 310-312 are executed; when the first priority is not higher than the second priority, the flow is ended.

In the embodiments of the invention in steps 308 to 309, as can be seen from steps 301 to 307, the user of the first sound box and the user of the target second sound box are playing using the sound boxes at the same time, and the playing contents and/or playing schedules of the first sound box and the target second sound box are not consistent, so that the listening effect of the user of the first sound box listening to the first sound box is affected, but at the same time, the user of the target second sound box listening to the target second sound box may also be affected by the first sound box. Therefore, by implementing the embodiment of the invention, the priority level can be set for each sound box based on the environment of multiple sound boxes, when multiple sound boxes are used simultaneously, the sound volume can be adjusted to the sound box with low priority level by judging the priority level of each sound box, so that the sound boxes can be reasonably regulated and controlled in the environment of multiple sound boxes, and the playing environment of the multiple sound boxes can be optimized.

310. And the control device positions a target second sound box corresponding to the target volume value according to the target volume value to obtain a target space position where the target second sound box is located, and obtains a first space position of the first sound box.

311. And the control device generates a volume adjusting instruction aiming at the target second loudspeaker box according to the spatial distance between the first spatial position and the target spatial position.

In the embodiment of the invention, the control device can generate the unified volume adjusting instructions for all the target second sound boxes, and further, different volume adjusting instructions can be generated for the target second sound boxes with different spatial distances in a targeted manner according to the spatial distance between the first spatial position and the target spatial position, so that the personalized control of the playing of multiple sound boxes is realized.

312. And the control device sends a volume adjusting instruction to the target second sound box so as to trigger the target second sound box to reduce the playing volume of the target second sound box according to the volume adjusting instruction.

It should be noted that, the above steps 310 to 312 may be triggered and executed after the first playing schedule is determined to be different from the second playing schedule in step 307, or triggered and executed after the first priority is determined to be higher than the second priority in step 309.

Therefore, by the method described in fig. 3, when a plurality of speakers are in a playing state at the same time, interference noise generated between different speakers can be reduced, thereby reducing the influence of the interference noise on the user experience; whether a person exists in the environment area where the current target second sound box is located can be judged through the environment image, and the playing of the target second sound box is paused in time when the absence of the person is judged, so that the power consumption of the target second sound box can be reduced, the waste of the electric quantity of the sound box is reduced, the generation of interference noise can be avoided from the source, and the use experience of a user is further improved; the target second sound box can play the second playing content in the preset volume and direction by changing the working mode of the target second sound box, so that the influence of the playing of the target second sound box on the playing quality of the first sound box is reduced, and the interference generated between the plurality of sound boxes during the simultaneous playing is reduced; in addition, the priority level can be set for each sound box based on the environment of multiple sound boxes, when multiple sound boxes are used simultaneously, the sound volume is adjusted to the sound box with low priority level by judging the priority level of each sound box, so that the sound boxes can be reasonably regulated and controlled in the environment of multiple sound boxes, and the playing environment of the multiple sound boxes is optimized; furthermore, different volume adjusting instructions can be generated for target second sound boxes with different spatial distances in a targeted manner according to the spatial distance between the first spatial position and the target spatial position, and personalized control over playing of the multiple sound boxes is achieved.
