Technical Field

The disclosure relates to the technical field of sound boxes, and in particular relates to a sound box playing control method, a sound box playing control device and a storage medium.

Background

Along with the development of intelligent home technology and the pursuit of people to high-quality home life, full-house sound brings shocked hearing enjoyment to the home life of people. The intelligent sound boxes are connected with each other through WiFi and synchronously play music, so that a user can also have immersive listening experience in the walking process. The terminal sound box takes the audio data from the server and transmits the audio data to sound boxes in all rooms through a wireless network. The same audio frame is ensured to be played in the same time through a certain synchronization mechanism.

However, users typically play music in only one or a portion of the room, and in rooms where no users are present, on the one hand, this results in a loss of power. On the other hand, because the sound box will occupy the network channel when transmitting data, if the network resource is occupied more, the system is more likely to be unstable, for example, the playing is asynchronous.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of the present disclosure. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure. Embodiments of the present disclosure are described in detail below with reference to the attached drawings.

The sound box playing control method provided by the embodiment of the disclosure can be applied to a plurality of intelligent devices connected through a wireless communication technology, and an application scene of sharing music among users is realized. In particular, a plurality of intelligent devices in the setting space belong to different subspaces respectively, and the plurality of intelligent devices comprise a main control intelligent device and a sub intelligent device. The intelligent device can be an intelligent sound box or other intelligent devices.

The popularization of intelligent sound boxes and the increasingly improved listening demands of users lead all companies to aim at improving the music playing function of the respective sound boxes, and one breakthrough progress is that the sound boxes are interconnected through a wireless network so as to realize the full-house playing function. The intelligent sound boxes are connected with each other through WiFi and synchronously play music, so that a user can also have immersive listening experience in the walking process. The sound box takes the music data from the server and transmits the music data to the sound boxes in all rooms through the wireless network. The same audio frame is ensured to be played in the same time through a certain synchronization mechanism, so that all intelligent sound boxes in the home synchronously play music.

In the related art, information interaction among a plurality of intelligent sound boxes is realized through WiFi interconnection. The master control sound box takes the audio data from the server, frames the audio data in equal time length, marks the corresponding time information for each audio frame, and sends the time information to other sub sound boxes in all rooms through WiFi packaging. And the other sub-sound boxes receive the audio frame package sent by the main control sound box through WiFi and analyze out audio data and time information. And when the audio frame packet is interacted, other sub-sound boxes need to interact with the master control sound box to realize the system clock alignment of the master control sound box and other sub-sound boxes, so that the data processing of the master control sound box and other sub-sound boxes is ensured to be on the same clock reference. On the basis of synchronizing the system clocks of the main control loudspeaker box and other sub-loudspeaker boxes, the audio data are respectively processed. After the main control loudspeaker box and other sub-loudspeaker boxes are set for fixed time, the same audio frame is played, so that the audio synchronous playing of a plurality of loudspeaker boxes is realized, and the listening experience of full house playing is achieved. However, in a home, a user can only play music in one or a part of rooms, and play music in a room without one, one wastes electric energy, and the more network resources are occupied due to the fact that the transmitted data occupy network channels, the more the network resources are occupied, the more likely that the whole system is unstable, for example, audio data cannot be played synchronously among a plurality of sound boxes.

In view of this, the present disclosure provides a method for controlling sound box playing, when determining that a sound box enables an audio playing function, obtaining audio data from a server through a main control sound box, and determining a target subspace in subspaces where a plurality of sub-sound boxes belong, where the target subspace is a subspace where a user is currently located, and the subspace is a complete space and is divided into one of a plurality of spaces. Further, the main control sound box sends the audio data acquired from the server to the sub-sound box in the space where the user is currently located, and the sub-sound box plays the audio based on the audio data. Based on the method, the sound box in the space selectively plays the audio data according to the current space of the user, so that the waste of energy sources is reduced, namely, the sound box in the current space, in which the user is not detected, is in an inactive state. Simultaneously, release the channel resource between the sub-audio box that carries out audio data with main control audio amplifier and not playing, reduce network load as far as possible, can promote the stability of system, and provide more stable hearing experience for the user. Therefore, compared with the mode of controlling the sound box to play in the related art, the sound box play control method provided by the disclosure is more flexible and intelligent.

Fig. 1 is a flowchart of a method for controlling playing of a sound box according to an exemplary embodiment, as shown in fig. 1, applied to a master sound box, including the following steps.

In the following disclosure embodiments, a sound box that communicates with a server and other sound boxes is referred to as a master sound box, and a sound box that communicates with a master sound box is referred to as a sub sound box, where the master sound box is used to control a plurality of sub sound boxes, and different sub sound boxes are included in different sub spaces in the same space. One or more different sub-bins may be included in the same subspace.

In step S11, when it is determined that the master control speaker enables the audio playing function, audio data is obtained from the server, and a target subspace is determined from subspaces to which the plurality of sub-speakers belong.

The target subspace is the subspace where the user is currently located. A subspace can be understood as any one room, such as: living room, kitchen, bedroom, etc.

In the embodiment of the disclosure, when it is determined that a user has started the audio playing functions of all the sound boxes in the room, the master control sound box acquires audio data from the server through a wireless transmission technology. And determining the room in which the user is currently located by receiving the signals transmitted by the sub-sound boxes in the subspace.

In step S12, the audio data is sent to the sub-speakers in the target subspace, and the sub-speakers in the target subspace are controlled to play audio based on the audio data.

In the embodiment of the disclosure, when the master control sound box determines which space has a user, the audio data obtained from the server is sent to the sub sound box in the space having the user, and the sub sound box in the space is controlled to play the decoded audio data.

In the method, a main control sound box determines a non-target subspace through an instruction sent by a sub-sound box in the subspace, wherein the non-target subspace is a subspace to which each set sub-sound box of a user does not exist. And under the condition that the main control sound box determines the non-target subspace, stopping sending the audio data to the sub-sound boxes in the non-target subspace.

In the embodiment of the disclosure, if the main control sound box determines that no user exists in the subspace, the main control sound box stops sending audio data to the sub-sound box in the space, and a channel between the main control sound box and the sub-sound box in the space is closed. And the channel resources between the main control sound box and the sub-sound box which does not play the audio data are released, so that the stability of the system is improved, and more stable hearing experience is provided for the user.

In the method, when all sound boxes are determined to enable the audio playing function, audio data are acquired from a server, and a target subspace is determined in subspaces to which a plurality of sub-sound boxes belong. And sending the audio data to a sub-sound box in the target subspace, and controlling the sub-sound box in the target subspace to play the audio based on the audio data. Through the method and the device, the sound box in the space selectively plays the audio data according to the current space of the user, so that the waste of energy sources is reduced. It will be appreciated that the master speaker will only transmit audio data to the sub-speakers in the space if a user is present in the space.

Based on the above embodiments, it can be known that the main control speaker determines the target subspace as a key step, and therefore, in the following disclosed embodiments, how the main control speaker determines the target subspace will be specifically described.

Fig. 2 is a flowchart illustrating a method for determining a target subspace according to an exemplary embodiment, wherein the target subspace is determined among subspaces to which a plurality of sub-sound boxes belong, as shown in fig. 2, including the following steps.

In step S21, a user detection result is determined.

The user detection result is determined by setting a sub-sound box in the subspace based on detection of human body activity of the user, and the user detection result comprises the presence or absence of the user.

In step S22, the subspace to which the target subspace of the user exists as the detection result is determined as the target subspace.

In the embodiment of the disclosure, if the sub-sound box set in the subspace detects that the human body activity of the user exists in the space, the main control sound box receives an instruction for confirming the existence of the user from the sub-sound box, and determines the subspace of the target sub-sound box with the existence of the user as the target subspace. If the sub-sound box set in the subspace does not detect that the human body activity of the user exists in the space, the main control sound box receives an instruction from the sub-sound box for confirming that the user does not exist.

In the present disclosure, a user detection result is determined. And determining the subspace of the target sound box with the user as the target subspace according to the detection result. Through the method and the device, based on the detection result instruction transmitted from the sub-sound box to the main control sound box, the main control sound box transmits the corresponding instruction to control the sub-sound box, and interaction between the sub-sound box and the main control sound box is achieved.

Fig. 3 is a flowchart illustrating a method for controlling a sub-box in a target subspace to perform audio playback based on audio data, as shown in fig. 3, by transmitting audio data to a sub-box in a target subspace, and controlling a sub-box in a target subspace to perform audio playback based on audio data, according to an exemplary embodiment, comprising the following steps.

In step S31, a target space identifier corresponding to the target subspace is determined.

The plurality of sub-sound boxes are corresponding to space identifiers, and the space identifiers are used for identifying subspaces to which the sub-sound boxes belong.

In the disclosed embodiments, the room environment is divided into a plurality of subspaces, such as: subspaces such as kitchen, living room, bedroom, etc. When the network is firstly configured, the space where the sound box is located is selected by a user, for example, the user can select the current space where the sound box is located through a telescopic list on a display screen of the sound box, and thus each sound box knows the current space environment. For example, sound box a and sound box B are currently placed in the living room; sound box C and sound box D are currently placed in the master bedroom, etc. Secondly, the sub-sound boxes in the target subspace are mutually perceived through an ultrasonic communication mode, and the subspace to which each sub-sound box belongs is determined. The sub-sound box sends the own space identification to the main control sound box, and the main control sound box stores the IP addresses or other identification IDs of all the sub-sound boxes in the sub-space in the list of the equipment, so that the target space identification corresponding to the target sub-space can be determined.

In step S32, the audio data is sent to the sub-speakers in the target subspace identified by the target space identifier, and the sub-speakers in the target subspace are controlled to play audio based on the audio data based on the target space identifier.

In one example, a user may select one of the sub-boxes within the target subspace in advance, detect whether there is user activity within the space through the sub-box, and send the detection result to the master speaker. The sound boxes with optimal performance can be set as the set sound box for detecting whether the user activity exists in the space or not through mutual perception of the sub sound boxes in the target subspace, and the detection result is sent to the set sound box for the main control sound box. If the user is currently active in the master bedroom, the sound box set in the master bedroom detects that the human body is active, the sound box sends a confirmation instruction to the master sound box, and the master sound box sends audio data to the sound box in the master bedroom and controls the sound box in the master bedroom to play audio.

In the present disclosure, a target space identifier corresponding to a target subspace is determined. And sending the audio data to the sub-sound boxes in the target subspace identified by the target space identification, and controlling the sub-sound boxes in the target subspace to play the audio based on the audio data based on the target space identification. Through the method and the device, the main control sound box can accurately control the sub-sound box in the space where the user exists to play the audio.

Wherein the user detection result includes presence or absence of a user.

In the embodiment of the disclosure, a sub-sound box is selected randomly in each subspace or according to the performance of the sub-sound box, and the sub-sound box transmits and receives ultrasonic waves. After the audio playing function of all the sound boxes is started, the selected sub-sound boxes in each subspace transmit ultrasonic waves to detect the human body activity of the user. In the disclosed embodiments, differential channel impulse response (dCIR) is employed to detect user human activity. The essence of this detection method is through dCIR in a real-time computing environment. When the user is not currently in subspace A, the dCIR value of the sub-box extraction ultrasonic wave in subspace A approaches 0. At this time, the sub-sound box set in the target subspace will send a command of no user in the space to the main control sound box. After receiving the instruction, the main control sound box sends corresponding instruction operation to the sub sound box. When the user is currently in subspace B, the dCIR value of the sub-box extraction ultrasound in subspace B will reflect the amplitude variation on dCIR. At this time, if the dCIR amplitude of the sub-speaker set in the target subspace changes, the speaker will send a user instruction to the master control speaker. After receiving the instruction, the main control sound box sends corresponding instruction operation to the sub sound box. By detecting the overall amplitude state of dCIR, it is possible to detect whether a user is present in the current subspace.

In the embodiment of the present disclosure, the application principle of dCIR is based on the following formula:

In this case, when the main control speaker receives the transmission instruction from the sub-speaker, it may be determined that the user detection result determined by the sub-speaker is that the user exists in the sub-space. And the main control sound box determines the subspace of the target sound box with the user as the target subspace according to the detection result.

In the embodiment of the disclosure, the sub-sound box in the subspace can also detect that no user exists in the current subspace.

In the embodiment of the disclosure, when the dCIR value of the ultrasonic wave extracted by the sub-sound box in the subspace approaches to 0, it is determined that no user exists in the subspace currently. When the fact that no user exists in the subspace is determined, the sub-sound box sends an instruction to the main control sound box to inform that no user exists in the space to which the sub-sound box belongs.

In the embodiment of the disclosure, when the main control sound box receives non-target subspace information sent by the sub-sound box, it is determined that no user exists in the space where the sub-sound box is located.

In step S81, the system clock between the sub-speaker and the main control speaker is checked.

In an embodiment of the present disclosure, fig. 9 shows a schematic diagram of a system clock calibrated between a master speaker and a sub-speaker. As shown in fig. 9, the master speaker and the sub-speaker transmit audio data while the master speaker and the sub-speaker are performing clock information interaction. The sub-sound box needs to calculate the system clock difference between itself and the main control sound box and adjust itself to the system clock consistent with the main control sound box. The sub-sound box sends time information to the main control sound box through WiFi at the moment TB0 according to the clock of the sub-sound box, the main control sound box receives the time information of the sub-sound box at the moment TA0 according to the clock of the sub-sound box, then the main control sound box sends the time information to the sub-sound box through WiFi at the moment TA1, and the sub-sound box receives the time information of the main control sound box at the moment TB 1. The sub-sound box uses 4 pieces of time information, namely TB0, TA1 and TB1, so that the system clock difference between the sub-sound box and the main control sound box can be calculated: t (T) _A0 -T _B0 ＝Δ+τ ₀ 、T _B1 -T _A1 ＝-Δ+τ ₁ Wherein delta represents the system clock error between the sub-enclosure and the master enclosure, τ ₀ And τ ₁ Is the WiFi transmission delay between the master speaker and the sub-speaker. The system clock error can be calculated as:and the sub-sound box compensates the own system clock by the clock difference delta, and the system clock is calibrated to be consistent with the system clock of the main control sound box. On the basis that all the sound boxes are aligned with the master control sound box clock, for the audio frame at the time T0, the audio frame is played at the time T0+1s, and synchronous playing of all the sound boxes is realized.

Fig. 10 shows a schematic diagram of sound play control. As shown in fig. 10, first, a division is made for the space where each sound box is located, and division of the subspace can be achieved through two forms of user configuration and automatic perception. The user cooperation means that when a user configures a network for a sound box, a subspace where the sound box is located is selected, for example, a living room is selected for the sound box A and the sound box B, and a master bedroom is selected for the sound box C and the sound box D, so that the sound box A and the sound box B know that the sound box A and the sound box B are in one subspace, and the sound box C and the sound box D know that the sound box C and the sound box D are in one subspace. The automatic perception is that the user does not need to select, the sound boxes are mutually perceived through ultrasonic communication, if the sound box A sends ultrasonic information, only the sound box B can receive the ultrasonic information, and the sound box B knows that the sound box A and the sound box D are in the same subspace because the sound box C and the sound box D are blocked by the wall body and cannot be received. Each sound box senses in sequence, and the subspaces where all the sound boxes are located can be finally divided. And taking the sound box A as a main control sound box, finally summarizing the information of the space where all the devices are located into the sound box A, and storing the IP addresses or other identification IDs of the devices in all the subspaces in a list. In this case, a relationship of relevance is established between the individual speakers. In the subspace 1, the sound box M detects a user through an ultrasonic technology, and if the sound box M detects that the user is in the subspace 1, an instruction is sent to the main control sound box to inform that the user is in the subspace 1. When the main control sound box receives the instruction from the sound box M, the main control sound box continuously sends audio data to the sound box M and the sound box N in the subspace 1. If the sound box M does not detect that the user is in the subspace 1, an instruction is sent to the main control sound box, and the fact that the user is not in the subspace 1 is informed. When the main control sound box receives the instruction from the sound box M, the main control sound box stops sending audio data to the sound box M and the sound box N in the subspace 1, and closes the channels between the main control sound box and the sound box M and the influence N. According to the method and the device, the playing function of the sound box in the room is stopped in the room without the existence of the user, so that unnecessary electric energy waste is saved; secondly, occupation of network resources is saved, network load is reduced, and stability of the system is improved.

The embodiment of the disclosure provides a sound box playing control method, which is applied to sub-sound boxes in various divided subspaces, wherein the sub-sound boxes are communicated with a main control sound box. When the child sound box detects that a user exists in the space through the ultrasonic technology, sending an instruction that the user exists to the main control sound box; when the sub-sound box detects that no user exists in the space through the ultrasonic technology, an instruction that no user exists is sent to the main control sound box. And under the condition that the main control sound box space is informed of the existence of a user, receiving the audio data and the playing control instruction from the main control sound box, decoding the data and playing the data.

Based on the same conception, the embodiment of the disclosure also provides a sound box playing control device.
