The sound is used as an independent sensory channel of a human body and has irreplaceable important influence on emotion and cognition of the human body, but the sound is towards all directions in the air propagation direction, and the sound can interfere with each other in the same space or adjacent spaces. When the sound environment is disturbed, the communication efficiency is reduced, and the language hearing of people is damaged. Nearly 1/3 of the time a human spends in sleep, which is an important condition for people to relieve fatigue, recover physical strength and maintain health. However, noise can make people not sleep or be awakened, and the old and the patients are more sensitive to noise interference. When sleep is disturbed, both work efficiency and health are affected. The research shows that: the continuous noise can accelerate the rotation from deep sleep to light sleep, so that people are dreamful and the time for deep sleep is shortened; a sudden noise may awaken a person. Generally, 40 db of continuous noise can affect 10% of people; 70 decibels can affect 50%; and the sudden movement noise can wake up 10% of people when the sudden movement noise is 40 decibels, and wake up 70% of people when the sudden movement noise reaches 60 decibels. The long-term sleep disturbance can cause insomnia, fatigue, weakness and memory deterioration, so as to generate neurasthenia syndrome and the like. In a high-noise environment, the morbidity of the disease can reach more than 50-60%.

Along with the development of cities, the proportion of people living at home is increased, different people have different requirements on sound environments, and the interference to other people is easily caused, for example, the old people are watching television, the young people are jumping to build a body and dance, children are on a class while reading English, and infants possibly sleep, and each person has own personalized sound environment requirements, but most living spaces at present cannot completely provide the independent environment.

Currently, the techniques associated with establishing a particular sound environment are directional sound production techniques.

The directional sound production technology controls the propagation direction, propagation range, propagation area and the like of sound from a sound source, and reduces the interference of noise caused by sound divergence propagation to surrounding people.

The directional sounding technology is based on a parametric array principle, audible sound waves are carried on ultrasonic waves (high-frequency signals with the frequency larger than 20 KHz), and the audible sound waves with high directivity are generated by utilizing the self-demodulation effect of air, so that a common divergent sound source is converted into a directional sound source. The sound source can transmit sound along a fixed path, so that the sound becomes a beam of 'sound posts', similar to light posts emitted by searchlights, and only people in the coverage area of the 'sound posts' can clearly hear the sound.

According to the acoustic theory, the higher the frequency of the sound wave is, the better the execution performance of the sound wave in the transmission process is, the ultrasonic wave has good directivity in the transmission process, the directional sounding technology is to modulate the sound wave in the living room onto the ultrasonic wave frequency band by utilizing the directivity characteristic of the ultrasonic wave through the acoustic technology and the algorithm, and the sound wave is sent to the air from left to right through the self-adjustment of the air, so that the directional transmission of the audible sound wave is realized.

As shown in fig. 1, directional sound can cause sound to propagate in a specified direction in the form of a narrow-band beam wave when sound is propagated, as compared with ordinary sound, which outputs sound that propagates in all directions.

As shown in fig. 2, the normal sound propagates from the center to the periphery, and the directional sound has more directivity, and can output sound in a specific direction, thereby reducing interference to surrounding people.

However, only using the directional sounding technology cannot cope with the complex situation that multiple people are in one room in real life and each user needs a personalized sleeping sound environment.

In view of this, the present application provides an audio system, which includes a plurality of directional speakers, and when the audio system enters a sleep mode, the directional speakers may be matched for each target user, then the head position information of each target user and the sleep cycle of each target user are obtained, and the audio corresponding to the sleep cycle of each target user is determined, so that a controller of the audio system controls the directional speakers matched with the target user to face the head of the user, and plays the audio corresponding to the sleep cycle of the target user. Therefore, the sound coverage range of the directional sound box comprises the head area of the target user, different audio is played according to different sleep cycles of the target user, and therefore a specific sleep sound environment is established for the target user more accurately.

For example: the communicator may include at least one of a Wi-Fi chip, a bluetooth communication protocol chip, a wired ethernet communication protocol chip, or other network communication protocol chip or near field communication protocol chip, and an infrared receiver. Directional sound 10 may communicate control signals and data signals between the communicator and controller 50. For example, the controller 50 sends a play instruction for the first audio to the directional sound, and the directional sound 10 starts playing the first audio after receiving the play instruction through the communicator.

The human-computer interaction device is used for realizing the interaction between the user and the directional sound equipment 10. The human-computer interaction device may comprise one or more of a physical key or a touch display panel. For example, the user may select the audio played by the directional sound equipment 10 through the human-computer interaction device, or may set the duration, volume, etc. of the audio played by the directional sound equipment 10 through the human-computer interaction device.

In some embodiments, the human body detection device 20 is used to detect the positions of various parts of the human body.

The controller 50 may obtain the sleep cycle of the user B according to the sleep detection apparatus, and further control the second directional sound 602 to play the audio corresponding to the sleep cycle of the user B, which will not affect the user a.

The following detailed description of the embodiments of the present application is made with reference to the accompanying drawings.

An embodiment of the present application provides a method for controlling a directional sound device, as shown in fig. 5, the method includes the following steps:

s101, when the sound system enters a sleep mode, the controller acquires head position information of each target user.

The target user is a user which is located in the space where the sound system is located and is in a sleeping state.

In some embodiments, the controller determines that the sound system enters the sleep mode in response to a setting operation by the user. For example, when a user sets the operation mode of the sound system to a sleep mode through a man-machine interaction device of a directional sound in the sound system, the controller controls the sound system to enter the sleep mode.

In some embodiments, the controller also performs zone division on the space in which the sound system is located. For example, as shown in fig. 6, the controller divides the space where the sound system is located into an area A1-a16 in the bed and an area B1-B18 outside the bed, and after the area where the head of the user is located is determined by the human body detection device, the controller controls the directional sound to face the area where the head of the user is located, so that accurate transmission of sound is realized.

In some embodiments, the controller may also obtain physical characteristic information of the target user, the physical characteristic information including one or more of a body size, height, or weight of the user. Furthermore, the controller can more accurately identify the head position information of the target user according to the body characteristic information of the target user, so that a good sound environment is established for the head position of the target user.

S102, according to the head position information of each target user and the installation position information of each directional sound, the controller determines the directional sound matched with each target user.

For example, as shown in fig. 4, when two target users are in a same room, the first directional sound 601 is closer to the head of user a, and the second directional sound 602 is closer to the head of user B, then user a matches with the first directional sound 601, user B matches with the second directional sound 602, and the first directional sound 601 outputs sound toward the head of user a without interfering with user B.

S103, for each target user, the controller acquires the current sleep cycle of the target user.

In some embodiments, the sleep cycle of the target user is divided into a WAKE period (WAKE), a non-rapid eye movement (NREM), and a Rapid Eye Movement (REM).

According to medical research, as shown in fig. 7, the frequency and rate of brain waves generated by a person during sleep are different, and thus sleep can be subdivided into three periods: a waking period, a non-rapid eye movement period, and a rapid eye movement period. Different sleep cycles are sensitive to sound differently, for example, 35 db sound during non-rapid eye movement does not wake up the user, whereas less than 35 db sound during rapid eye movement wakes up the user.

Therefore, by acquiring the current sleep cycle of the target user, the controller can control the directional sound matched with the target user to aim at different sleep cycles of the target user, and establish different sleep sound environments for the user, thereby better serving each target user.

And S104, based on the sleep cycle of the target user and the head position information of the target user, the controller controls the directional sound matched with the target user to play the audio corresponding to the sleep cycle of the target user towards the head of the target user.

In some embodiments, the controller of the sound system may also obtain auditory characteristic information of each target user, the auditory characteristic information including one or more of the target user's age, physical state, gender, or auditory habits. And then, the controller determines the audio corresponding to the sleep cycle of each target user according to the auditory characteristic information of the target user. Therefore, the audio corresponding to each sleep cycle can better accord with the personal condition of the target user, so that better sleep feeling can be brought to the user when the directional sound box plays the audio corresponding to the sleep cycle where the target user is located.

In some embodiments, during the process that the directional sound plays the audio corresponding to the sleep cycle in which the target user is currently located, the controller also tracks the head of the target user through the human body detection device. When the head of the target user moves out of the sound coverage range of the directional sound transmission mechanism, the controller controls the driving mechanism of the directional sound box to drive the directional sound transmission mechanism to rotate, so that the sound coverage range of the directional sound transmission mechanism comprises the area where the head of the target user is located. Therefore, the controller can control the directional sound transmission mechanism to flexibly rotate, so that the sound coverage range of the directional sound transmission mechanism comprises the head area of the target user, and the sound output by the directional sound transmission mechanism can accurately create a sleeping sound environment suitable for the target user.

In some embodiments, the format of the audio corresponding to the sleep cycle in which the target user is currently located may be in MP3 format or AAC format. The specific format of the audio corresponding to the sleep cycle in which the target user is currently located is not specifically limited in the present application.

The technical scheme shown in fig. 5 brings at least the following beneficial effects: when the sound box system enters a sleep mode, the controller of the sound system acquires the head position information of each target user, so that the directional sound is matched for each target user according to the head position information of each target user and the installation position information of each directional sound, and each target user is provided with the directional sound for serving the target user. The controller acquires the sleep cycle of each target user, and further can control the directional sound matched with the target user to play the audio corresponding to the sleep cycle of the target user towards the head of the target user, so that the directional sound can establish a unique sound environment for the target user, and other people cannot be interfered.

In some embodiments, as shown in fig. 8, the step S102 may be implemented as the following steps:

and S1021, determining the number of the directional sounds matched with each target user by the controller according to the number of the directional sounds contained in the sound system and the number of the target users.

In some embodiments, step S1021 may also be implemented as: when the number of the target users is larger than 1, the controller determines the number of the directional sounds matched with each target user according to the number of the directional sounds contained in the sound system, the number of the target users and the priority of the target users. And the number of the directional sounds matched with the target user with high priority is greater than or equal to that of the directional sounds matched with the target user with low priority.

Illustratively, when the number of target users is 3 and the sound system includes 5 directional sounds, the controller first determines that the number of directional sounds matched with each of the three target users is 1, and then matches the remaining two directional sounds with the target user with the highest priority.

Optionally, the priority may be ranked according to the physical characteristic information of the target user or the auditory characteristic information of the target user, or may be set by the target user. For example, the higher the age, or the higher the weight.

And S1022, determining the directional sound matched with each target user according to the number of the directional sound matched with each target user, the head position information of each target user and the installation position information of each directional sound.

For example, if it is determined that the priority of the user a is the highest and 3 directional sounds are matched, it is determined that the directional sound matched with the user a is the 3 directional sounds closest to the head position of the user a; the priority of the user B is lower than that of the user A, the number of the matched directional sounds is 2, and after the user A is matched with the directional sounds, 2 directional sounds which are closest to the head position of the user B are determined from the rest directional sounds to serve as the directional sounds matched with the user B; and repeating the steps until all the target users are matched with the directional sound.

The technical scheme shown in fig. 8 brings at least the following beneficial effects: the controller can firstly determine the number of the directional sound equipment matched with each target user according to the number of the target users and the number of the directional sound equipment, and then accurately and reasonably match the directional sound equipment for each target user by combining the head position information of each target user and the installation position information of each directional sound equipment, so that the directional sound equipment can better serve the target users, and a specific sound environment is established for each target user.

The following exemplary description of the control flow of the sound system:

as shown in fig. 9, after the sound system is set, the controller first performs region division on the space where the sound system is located, and learns the feature information of each target user; and then detecting the head area of each target user in the space where the sound system is located, further matching the directional sound for each target user, and controlling the directional sound to face the head of the target user matched with the directional sound, thereby creating a unique sound environment belonging to the target user for the target user.

In some embodiments, for each target user, when the current time reaches the preset wake-up time of the target user, the controller controls the directional sound matched with the target user to play audio for waking up the target user towards the head of the target user. The audio for waking up the target user may be set by the target user, or may be matched by the controller for the target user.

Illustratively, the target user B sets an alarm clock at 7 am, and the controller controls the directional sound matched by the target user B to face the head of the target user B, and plays the audio of the target user B awakened by the user at 7 am.

In this way, the controller can control the directional sound to face the head of the target user, so that when the audio for waking up the target user is played at the preset wake-up time of the target user, only the target user is woken up, and other people in the same space cannot be interfered.

In some embodiments, the controller obtains a voice command and determines a target user who issues the voice command; and then, controlling the directional sound matched with the target user who sends the voice instruction to execute the operation indicated by the voice instruction. For example, when the controller receives a voice instruction of "start playing the first audio", the controller recognizes the voice instruction, and determines that the voice instruction is sent by the target user C, the controller controls the directional sound matched with the target user C to face the head of the target user C, and starts playing the first audio.

Therefore, the controller can recognize the voice command of the target user, so that the target user sending the voice command is served in a targeted manner, and other people cannot be interfered.

In some embodiments, the sound system may also be linked with other home devices to create a regional playing environment for the target user. The other household appliances can be indoor home theaters, televisions, projectors, mobile phones, tablets, computers and other appliances.

For example, when the target user is located on a sofa, the controller can control directional sound equipment around the sofa to be linked with a television in front of the sofa, so that the sound of the television is played to the sofa area, an immersive sound environment is established for the target user, and better use experience is brought to the target user.

For another example, when the target user exercises in the living room, the controller can control the directional sound equipment in the living room to face the head of the target user, and play music in a mobile phone or a television, so that better use experience is brought to the target user.

In some embodiments, when multiple users are in the same space, the controller may also control the sound system to establish a specific sound environment for each target user for any area of the room where each target user is located. The human body detection device in the sound system can be fixedly mounted on a wall, and the sound detection device can be an intelligent bracelet worn by a user, an ornament with a sound sensing function, a sound sensor of a decorative article shape placed around the user, a mobile phone, a portable MIC sensor and the like.

For example, when the user D listens to music, the user E is in a sleep state, and the user F watches tv, the controller may control the directional sound device matched with the user D to play sports music set by the user D toward the head of the user D, control the directional sound device matched with the user E to play audio corresponding to the sleep cycle in which the user E is located toward the head of the user E, and control the directional sound device matched with the user F to play sound of the tv toward the head of the user F, so as to establish a specific sound environment for each user in a shared room without disturbing other users.

Therefore, by arranging the sound system indoors, a specific sound environment can be established for a specific indoor area by utilizing the characteristics of good sound gathering property, small sound information loss and strong sound propagation directivity of the directional sound, and different requirements of different users are met.
