Description

Technical Field

[0001] The present application relates to the field of audio technology, and in particular to an audio system and a control method thereof. Background Art

[0002] Humans spend one-third of their time sleeping, and sleep is an important condition for eliminating fatigue, restoring physical strength and maintaining health.

[0003] At present, people can play music through speakers to help them sleep, but the sound output by the speakers is omnidirectional and diffuse, which cannot adapt to the sleeping habits of everyone in the room. When multiple people sleep in the same space, everyone's sleeping state is different. For example, some people snore, some people turn over, and some people talk in their sleep. These actions will more or less disturb the sleep quality of others. Users can only choose headphones or earplugs to avoid interference from external sounds, but wearing earplugs to sleep is not comfortable, and wearing headphones can also cause hearing damage. Summary of the invention

[0004] The embodiments of the present application provide a sound system and a control method thereof, which are used to provide a sound environment suitable for each user for multiple users who are in the same space and in a sleeping state.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0037] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, when describing a pipeline, the "connected" and "connection" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0038] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0039] As an independent sensory channel of the human body, sound has an irreplaceable and important influence on human emotions and cognition. However, the propagation direction of sound in the air is in all directions, and the sounds in the same space or adjacent spaces will interfere with each other. When the sound environment is disturbed, the communication efficiency will be reduced at the least, and people's language hearing will be damaged at the worst. Nearly one-third of human time is spent in sleep, and sleep is an important condition for humans to eliminate fatigue, restore physical strength, and maintain health. However, noise can make people unable to sleep or wake up, and the elderly and patients are more sensitive to noise interference. When sleep is disturbed, work efficiency and health will be affected. Studies have shown that continuous noise will accelerate the transition from deep sleep to light sleep, make people dream more, and shorten the time of deep sleep; sudden noise can wake people up. Generally speaking, 40 decibels of continuous noise can affect 10% of people; 70 decibels can affect 50%; and sudden noise at 40 decibels can wake up 10% of people, and at 60 decibels, it can wake up 70% of people. Long-term interference with sleep can cause insomnia, fatigue, memory loss, and even neurasthenia syndrome, etc. In a high-noise environment, the incidence of this disease can reach more than 50-60%.

[0040] With the development of cities, people spend more and more time indoors at home. Different people have different demands for the sound environment, which can easily cause interference to others. For example, the elderly are watching TV, young people are dancing, children are taking English online classes, and infants may be sleeping. Everyone has their own personalized sound environment needs, but most living spaces now cannot fully provide this independent environment.

[0041] Currently, technologies related to establishing a specific sound environment include directional sound technology.

[0042] When an object vibrates, it generates sound waves. Low-frequency sound waves usually propagate in all directions with the sound source as the center. Sound waves that can be heard by the human ear are low-frequency sound waves, also called audible sound waves. Audible sound waves propagate in all directions, and the sound pressure in each direction is also different. The directional sound technology controls the propagation direction, range, and area of ​​sound from the sound source, reducing the interference of noise caused by the divergent propagation of sound to people around.

[0043] Directional sound technology is based on the principle of parametric array, which carries audible sound waves onto ultrasonic waves (high-frequency signals with a frequency greater than 20KHz), and uses the self-demodulation effect of air to generate audible sound waves with high directivity, so that ordinary divergent sound sources are transformed into directional sound sources. The sound source can transmit sound along a fixed path, turning the sound into a beam of "sound column", similar to the beam of light emitted by a searchlight, and only people in the coverage area of ​​the "sound column" can hear the sound clearly.

[0044] According to acoustic theory, the higher the frequency of the sound wave, the better its execution in the propagation process. Ultrasonic waves have good directionality during transmission. Directional sound technology utilizes the directional characteristics of ultrasonic waves. Through acoustic technology and algorithms, the living room sound waves are modulated to the ultrasonic frequency band, and sent to the air left and right through the self-adjustment of the air, thereby realizing the directional propagation of audible sound waves.

[0045] like Figure 1 As shown, compared with ordinary speakers, directional speakers can make the sound propagate in a specified direction in the form of a narrow-band sound beam wave, while the sound output by ordinary speakers is propagated in all directions.

[0046] like Figure 2 As shown, ordinary speakers spread sound from the center to the surroundings, while directional speakers spread sound in a more directional manner and can output sound in a specific direction, reducing interference to people around.

[0047] However, if only directional sound technology is used, it cannot cope with the complex situation in real life where multiple people are in the same room and each user requires a personalized sleeping sound environment.

[0048] In view of this, the present application provides a sound system, which includes multiple directional speakers. When the speaker system enters the sleep mode, the directional speakers can be matched for each target user, and then the head position information of each target user and the current sleep cycle of each target user can be obtained to determine the audio corresponding to the current sleep cycle of each target user. Then, the controller of the sound system controls the directional speakers matched with the target user to face the user's head and play the audio corresponding to the current sleep cycle of the target user. Therefore, the sound coverage of the directional speakers includes the area where the head of the target user is located, and different audios are played for different sleep cycles of the target user, thereby more accurately establishing a specific sleep sound environment for the target user.

[0049] like Figure 3 As shown, the present application provides a sound system 1 suitable for multiple people in the same space. The sound system 1 includes multiple directional speakers 10 and a controller 50. Optionally, the sound system 1 may also include one or more of a human detection device 20, a sound detection device 30, and a sleep cycle detection device 40.

[0050] In some embodiments, the directional sound 10 is a device for propagating sound in a fixed direction. The directional sound 10 can also be called a directional sound device, a directional sound box, a directional speaker, a directional loudspeaker, an ultrasonic directional sound, a directional loudspeaker, a directional playback sound, a directional propagation sound box, etc.

[0051] In some embodiments, the directional speaker 10 includes: a housing, a directional sound transmission mechanism, a driving mechanism, a display, a communicator, and a human-computer interaction device.

[0052] The shell is used to protect the electrical components in the directional speaker 10, and to close the channel where the inside of the directional speaker 10 contacts the outside, so as to avoid damage to the electrical components.

[0053] Optionally, the shell may include an external horizontally rotating spherical shell and an internal spherical up and down rotating core, similar to the structure of a camera that can rotate 360°, which can achieve flexible rotation of the directional speaker and make the directional speaker output sound at a more comprehensive angle.

[0054] The directional sound transmission mechanism is used to transmit audio signals in a fixed direction, and the directional sound transmission mechanism may include a low-frequency radio wave signal generator, an ultrasonic carrier signal generator and an ultrasonic transducer.

[0055] The driving mechanism is used to drive the directional sound transmission mechanism to rotate.

[0056] The display may be a liquid crystal display or an organic light-emitting diode (OLED) display. The specific type, size, and resolution of the display are not limited. The display may be used to display a control panel of the directional speaker 10. The directional speaker 10 may provide feedback to the user through the display on the current working parameters of the directional speaker 10, such as the name of the audio being played, the duration of the audio being played, etc.

[0057] The communicator is a component for communicating with an external device or an external server according to various communication protocol types. 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, and other network communication protocol chips or a near field communication protocol chip, and an infrared receiver. The directional speaker 10 may transmit control signals and data signals between the communicator and the controller 50. For example, the controller 50 sends a play instruction for the first audio to the directional speaker, and the directional speaker 10 receives the play instruction through the communicator and starts playing the first audio.

[0058] The human-computer interaction device is used to realize the interaction between the user and the directional speaker 10. The human-computer interaction device may include one or more of a physical button or a touch display panel. For example, the user can select the audio played by the directional speaker 10 through the human-computer interaction device, and can also set the duration and volume of the audio played by the directional speaker 10 through the human-computer interaction device.

[0059] In some embodiments, the human body detection device 20 is used to detect the position of various parts of the human body. Exemplarily, the human body detection device 20 can be a radar wave detection device, an infrared imager, an image acquisition device, etc. Optionally, the human body detection device 20 can be integrated with other household appliances. For example, the human body detection device 20 can be installed on an air conditioner or on a lighting device. Optionally, the human body detection device 20 adopts a structure that can rotate 360° to achieve comprehensive detection of the human body position.

[0060] In some embodiments, the sound detection device 30 is a device for detecting sound in a specific area. Optionally, in the sound system 1, one or more sound detection devices 30 can be provided according to the number of users to detect the sound environment of different user areas, which is not limited in the embodiments of the present application.

[0061] In some embodiments, the sleep cycle detection device 40 is a device for detecting the sleep cycle of the user. For example, the sleep cycle detection device 40 can be a brain wave detector, a smart bracelet, etc.

[0062] In some embodiments, the controller 50 refers to a device that can generate an operation control signal according to the instruction operation code and the timing signal to instruct each device in the sound system 1 to execute the control instruction. Exemplarily, the controller 50 can be a central processing unit (CPU), a general-purpose processor network processor (NP), a digital signal processor (DSP), a programmable logic device (PLD), a microprocessor, a microcontroller or any combination thereof. The controller 50 can also be other devices with processing functions, such as circuits, devices or software modules, and the embodiments of the present application do not impose any restrictions on this.

[0063] In some embodiments, the controller 50 may establish a communication connection with the directional speaker 10 , the human body detection device 20 , the sound detection device 30 , and the sleep cycle detection device 40 by using WIFI, Bluetooth, or the like.

[0064] In some embodiments, based on the communication connection between the controller 50 and the directional speaker 10 , the controller 50 can control the audio played by the directional speaker 10 and the direction in which the directional speaker 10 outputs the sound.

[0065] In some embodiments, based on the communication connection between the controller 50 and the human body detection device 20 , the controller 50 can obtain the user's head position information through the human body detection device 20 .

[0066] In some embodiments, based on the communication connection between the controller 50 and the sound detection device 30, the controller 50 can receive the user's voice command through the sound detection device 30. For example, the user says "play the first audio", and after the controller 50 receives the user's voice through the sound detection device 30, it controls the directional speaker 10 to start playing the first audio.

[0067] In some embodiments, based on the communication connection between the controller 50 and the sleep cycle detection device 40 , the controller 50 can obtain the current sleep cycle of the user through the sleep cycle detection device 40 .

[0068] In some embodiments, the directional speaker 10, the human body detection device 20, the sound detection device 30, the sleep cycle detection device 40, and the controller 50 may be five independent devices. Alternatively, the human body detection device 20, the sound detection device 30, the sleep cycle detection device 40, and the controller 50 may also be integrated on the directional speaker 10.

[0069] Taking two users in the same room as an example, a possible deployment of the sound system 1 is described in detail below.

[0070] like Figure 4 As shown, a first human body detection device 501, a second human body detection device 502, a first directional sound 601, a second directional sound 602, a first sound detection device 701, a second sound detection device 702, a sleep cycle detection device 40 (not shown) and a controller 50 (not shown) are arranged at the head of the bed.

[0071] The first human detection device 501 specifically detects the turning over, moving, and other actions of user A in bed, and accurately determines the head position of user A; the second human detection device 502 specifically detects the turning over, moving, and other actions of user B in bed, and accurately determines the head position of user B.

[0072] The first directional speaker 601 is directed toward the head position of user A. When playing audio, the sound coverage range of the directional sound transmission mechanism can include the area where the head of user A is located.

[0073] The second directional speaker 602 is directed toward the head position of user B. When playing audio, the sound coverage range of the directional sound transmission mechanism can include the area where the head of user B is located.

[0074] The first sound detection device 701 is used to obtain the voice command of user A, so that the controller 50 can control the first directional sound 601 to perform corresponding operations according to the voice command of user A.

[0075] The first sound detection device 702 is used to obtain the voice command of user B, so that the controller 50 can control the second directional sound 602 to perform corresponding operations according to the voice command of user B.

[0076] For example, when user A is not asleep and user B is asleep, the controller 50 can control the first directional speaker 601 to play the audio indicated by user A according to the voice command of user A, without disturbing the sleep of user B. The controller 50 can obtain the current sleep cycle of user B according to the sleep detection device, and then control the second directional speaker 602 to play the audio corresponding to the current sleep cycle of user B, without affecting user A.

[0077] The specific scheme of the present application is described in detail below in conjunction with the accompanying drawings.

[0078] The present application embodiment provides a method for controlling directional sound. Figure 5 As shown, the method comprises the following steps:

[0079] S101: When the audio system enters a sleep mode, the controller obtains head position information of each target user.

[0080] The target users are users who are in the space where the audio system is located and are in a sleeping state.

[0081] In some embodiments, in response to a user's setting operation, the controller determines that the audio system enters the sleep mode. For example, the user sets the working mode of the audio system to the sleep mode through a human-computer interaction device of a directional audio in the audio system, and the controller controls the audio system to enter the sleep mode.

[0082] In some embodiments, the controller may further divide the space where the sound system is located into zones. Figure 6 As shown, the controller divides the space where the sound system is located into the area A1-A16 inside the bed and the area B1-B18 outside the bed. After determining the area where the user's head is located through the human body detection device, the controller controls the directional sound to be directed toward the area where the user's head is located, thereby achieving accurate sound transmission.

[0083] In some embodiments, the controller may also obtain the target user's physical characteristic information, which includes one or more of the user's body shape, height, or weight. Furthermore, the controller may more accurately identify the target user's head position information based on the target user's physical characteristic information, thereby establishing a good sound environment for the user based on the target user's head position.

[0084] S102: According to the head position information of each target user and the installation position information of each directional speaker, the controller determines a directional speaker that matches each target user.

[0085] For example, Figure 4 As shown, when two target users are in the same room, the first directional speaker 601 is closer to the head of user A, and the second directional speaker 602 is closer to the head of user B. User A is matched with the first directional speaker 601, and user B is matched with the second directional speaker 602. The first directional speaker 601 outputs sound toward the head of user A and will not interfere with user B.

[0086] S103: For each target user, the controller obtains the current sleep cycle of the target user.

[0087] In some embodiments, the target user's sleep cycle is divided into a wakeful period (WAKE), a non-rapid eye movement (NREM) period, and a rapid eye movement (REM) period.

[0088] According to medical research, Figure 7 As shown in the figure, the frequency and rate of brain waves produced by people during sleep are different, and sleep can be divided into three cycles: wakefulness, non-rapid eye movement, and rapid eye movement. Different sleep cycles have different sensitivity to sound. For example, in the non-rapid eye movement period, a sound of 35 decibels cannot wake the user, but in the rapid eye movement period, a sound below 35 decibels can wake the user.

[0089] In this way, by obtaining the current sleep cycle of the target user, the controller can control the directional audio matched with the target user to establish different sleep sound environments for the user according to the different sleep cycles of the target user, thereby better serving each target user.

[0090] S104: Based on the current sleep cycle of the target user and the head position information of the target user, the controller controls the directional speaker matched with the target user to play the audio corresponding to the current sleep cycle of the target user toward the head of the target user.

[0091] In some embodiments, the controller of the audio system can also obtain auditory feature information of each target user, and the auditory feature information includes one or more of the target user's age, physical condition, gender, or auditory habits. Then, the controller determines the audio corresponding to the sleep cycle of each target user based on the auditory feature information of the target user. Thus, the audio corresponding to each sleep cycle can better meet the personal situation of the target user, so that when the directional audio plays the audio corresponding to the sleep cycle of the target user, it can bring a better sleep experience to the user.

[0092] In some embodiments, while the directional speaker is playing the audio corresponding to the target user's current sleep cycle, the controller will also track the movement of the target user's head through a human body detection device. When the target user's head moves out of the sound coverage range of the directional sound transmission mechanism, the controller controls the driving mechanism of the directional speaker to drive the directional sound transmission mechanism to rotate so that the sound coverage range of the directional sound transmission mechanism includes the area where the target user's head is located. In this way, the controller can control the directional sound transmission mechanism to rotate flexibly so that the sound coverage range of the directional sound transmission mechanism includes the area where the target user's head is located, so that the sound output by the directional sound transmission mechanism can accurately create a sleep sound environment suitable for the target user.

[0093] In some embodiments, the audio format corresponding to the target user's current sleep cycle may be in MP3 format or AAC format. The present application does not specifically limit the specific format of the audio corresponding to the target user's current sleep cycle.

[0094] Figure 5 The technical solution shown brings at least the following beneficial effects: when the speaker system enters the sleep mode, the controller of the sound system obtains the head position information of each target user, and matches the directional speakers to each target user according to the head position information of each target user and the installation position information of each directional speaker, so that each target user has a directional speaker to serve him. The controller obtains the sleep cycle of each target user, and then controls the directional speakers matched by the target user to play the audio corresponding to the current sleep cycle of the target user toward the head of the target user, so that the directional speakers can create a unique sound environment for the target user without causing interference to others.

[0095] In some embodiments, Figure 8 As shown, the above step S102 can be specifically implemented as the following steps:

[0096] S1021. According to the number of directional speakers included in the sound system and the number of target users, the controller determines the number of directional speakers matching each target user.

[0097] In some embodiments, step S1021 may also be implemented as follows: when the number of target users is greater than 1, the controller determines the number of directional speakers matched to each target user according to the number of directional speakers included in the sound system, the number of target users, and the priority of the target users. The number of directional speakers matched to a target user with a high priority is greater than or equal to the number of directional speakers matched to a target user with a low priority.

[0098] Exemplarily, when the number of target users is 3 and the sound system includes 5 directional speakers, the controller first determines that the number of directional speakers matched to each of the three target users is 1, and then matches the remaining two directional speakers to the target user with the highest priority.

[0099] Optionally, the priority may be sorted according to the target user's physical feature information or the target user's auditory feature information, or may be set by the target user himself. For example, the older the age, the higher the priority, or the heavier the weight, the higher the priority.

[0100] S1022: Determine the directional speakers that match each target user according to the number of directional speakers that match each target user, the head position information of each target user, and the installation position information of each directional speaker.

[0101] For example, if it is determined that user A has the highest priority and is matched with 3 directional speakers, then the directional speakers that match user A are determined to be the 3 directional speakers that are closest to the head position of user A; the priority of user B is lower than that of user A, and the number of matched directional speakers is 2, then after completing the matching of user A and the directional speakers, two directional speakers that are closest to the head position of user B are determined from the remaining directional speakers as the directional speakers that match user B; and so on, until all target users are matched with directional speakers.

[0102] Figure 8 The technical solution shown brings at least the following beneficial effects: the controller can first determine the number of directional speakers matching each target user based on the number of target users and the number of directional speakers, and then combine the head position information of each target user and the installation position information of each directional speaker, so as to accurately and reasonably match the directional speakers for each target user, so that the directional speakers can better serve the target users and establish a specific sound environment for each target user.

[0103] The following is an exemplary description of the control process of the sound system:

[0104] like Fig. 9As shown, after the sound system is set up, the controller first divides the space where the sound system is located into areas and learns the characteristic information of each target user; then it detects the area where the head of each target user is located in the space where the sound system is located, and then matches directional sound for each target user, and controls the directional sound to be directed toward the head of the target user that matches it, thereby creating a unique sound environment for the target user.

[0105] In some embodiments, for each target user, when the current time reaches the wake-up time preset by the target user, the controller controls the directional speaker matched with the target user to play the audio used to wake up the target user toward the head of the target user. The audio used to wake up the target user can be set by the target user himself or matched by the controller for the target user.

[0106] For example, target user B sets an alarm for 7 a.m., then the controller controls the directional speaker matched with target user B to face the head of target user B, and plays the audio for waking up target user B at 7 a.m.

[0107] In this way, the controller can control the directional speaker to face the head of the target user, so that when the audio used to wake up the target user is played at the wake-up time preset by the target user, only the target user will be woken up and other people in the same space will not be disturbed.

[0108] In some embodiments, the controller obtains a voice command and determines the target user who issued the voice command; then, the controller controls the directional speaker matched by the target user who issued the voice command to perform the operation indicated by the voice command. For example, the controller receives a voice command "start playing the first audio", the controller identifies the voice command, and determines that the voice command is issued by the target user C, then the controller controls the directional speaker matched by the target user C to face the head of the target user C and start playing the first audio.

[0109] In this way, the controller can recognize the voice command of the target user, thereby providing targeted services to the target user who issued the voice command without causing interference to other people.

[0110] In some embodiments, the sound system can also be linked with other home appliances to create a regional playback environment for target users. Other home appliances can be indoor home theaters, televisions, projectors, mobile phones, tablets, computers and other devices.

[0111] For example, when the target user is sitting on the sofa, the controller can control the directional speakers around the sofa to link with the TV in front of the sofa, play the sound of the TV to the sofa area, create an immersive sound environment for the target user, and bring a better user experience to the target user.

[0112] For another example, when the target user is exercising in the living room, the controller can control the directional speakers in the living room to face the target user's head and play music from the mobile phone or TV, giving the target user a better user experience.

[0113] In some embodiments, when multiple users are in the same space, the controller can also control the sound system to establish a specific sound environment for each target user in any area of ​​the room. The human detection device in the sound system can be fixedly mounted on the wall, and the sound detection device can be a smart bracelet worn by the user, an ornament with sound sensing function, a sound sensor in the shape of an ornament placed around the user, a mobile phone, a portable MIC sensor, etc.

[0114] For example, when user D is listening to music, user E is sleeping, and user F is watching TV, the controller can control the directional speakers matched by user D to play sports music set by user D towards the head of user D, control the directional speakers matched by user E to play audio corresponding to the sleep cycle of user E towards the head of user E, and control the directional speakers matched by user F to play TV sound towards the head of user F, thereby creating a specific sound environment for each user in the same room without disturbing other users.

[0115] In this way, by setting up a sound system indoors, we can use the characteristics of directional sound, such as good sound concentration, small sound information loss, and strong sound propagation directionality, to create a specific sound environment for specific areas indoors to meet the different needs of different users.
