Technical Field
[0001] This application belongs to the technical field of home theaters, and particularly relates to an intelligent guidance system, a control method and a device for an audio system. Background Art
[0002] When a user plays music and other audio through a speaker in an enclosed space, the sound wave signal output by the speaker may be affected by the speaker characteristics, space reflection, etc., resulting in superposition or cancellation, which may cause distortion of the audio signal, thereby affecting the sound quality of the audio signal and the user's auditory experience. To ensure the effect of the speaker playing the audio signal, it is necessary to perform equalization processing on the audio signal to improve the listening experience of the user at various positions in the space. On the one hand, in the prior art, the equalization processing of the audio signal usually adopts an inherent algorithm, without considering the placement position of the speaker, resulting in poor audio equalization effect; on the other hand, since different usage environments have the best placement positions that match them, the existing paper manuals usually recommend approximate placement position guidance for the theoretically used space, and cannot be flexibly changed according to the changes in the user's home environment. On the one hand, the best sound effect cannot be exhibited in a specific usage space; on the other hand, it cannot intuitively and effectively guide the user to place the audio system. Summary of the Invention
[0003] The purpose of this application is to at least overcome one of the above-mentioned deficiencies of the prior art, and provide an intelligent guidance system, a control method and a device for an audio system, which can greatly improve the user experience of the product.

The system includes: at least one processor communicatively connected to the audio system; a computer-readable medium including instructions stored thereon, which when executed by the at least one processor, cause the at least one processor to perform the operations described above.
[0006] On the other hand, the present application also provides a device for guiding a user to place an audio system, including a graphical user interface provided by a client device. The graphical user interface is configured to receive a first user input for indicating whether the user needs placement guidance; in response to the first user input, output placement guidance information or output placement guidance information and a graphical user interface for receiving a second user input, where the second user input indicates whether the user has completed the placement; or in response to the first user input, return to the current graphical user interface; and output placement guidance information or return to the current graphical user interface after responding to the second user input.

Detailed implementation manners
[0010] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0011] The terms "including" and "having" in the specification, claims and drawings of the present application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device, etc. that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices, etc.
[0012] The phrase "in an embodiment" mentioned herein means that the specific features, structures or characteristics described in combination with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art can explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0013] It should be understood that in the present application, "at least one (item)" means one or more, "a plurality" means two or more, "at least two (items)" means two or three and three or more, and "and / or" is used to describe the association relationship of associated objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and both A and B exist at the same time. Among them, A and B can be singular or plural. The character " / " generally means that the associated objects before and after are in an "or" relationship. "At least one (one) of the following" or its similar expression refers to any combination of these items, including any combination of single item (one) or plural items (ones). For example, at least one (one) of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.
[0014] In an audio system composed of multiple audio devices, for most products, when wiring and placing the products, the approximate placement positions of each audio device relative to the display device in the room are generally recommended through paper instructions. There is a lack of effective specific suggestions for fine-tuning the placement of audio devices for different usage environments. Therefore, the audio system cannot present the best sound effects adapted to its specifications in a specific usage environment. In addition, the placement suggestions provided through paper instructions are often ignored by users, resulting in random placement of audio devices and poor product sound effects. This application provides an intelligent guidance system, control method, and device for an audio system, which can provide targeted placement guidance information for users in a more intuitive way, effectively improving the audio performance of the audio system in a specific environment. In addition, this application provides intuitive placement guidance information to users through an interactive graphical user interface or voice prompts, enabling the best placement method of the audio system to be more directly conveyed to users. Even if the user does not place the audio devices according to or does not fully follow the guidance suggestions, the guidance system, control method, and device disclosed in this application can convey to the user the effect of the placement position of the audio devices on the improvement of sound effects.
[0015] The audio system involved in this application includes multiple audio devices connected by audio transmission. The audio system control method includes obtaining the device characteristic parameters of the audio system and the acoustic characteristic parameters of the environment in which it is located; calculating placement guidance information based on the device characteristic parameters and the acoustic characteristic parameters. It should be noted that the device characteristic parameters of the audio system can be obtained after the APP is connected to the audio system through Bluetooth or other means. The device characteristic parameters of the audio system include, but are not limited to, the number of audio devices in the audio system, the type of audio devices, the specific distribution of speaker horns, the speaker size, the sound pressure level, the operating frequency range, and other information.
[0016] When the audio system is used in an indoor space, the environmental acoustic characteristic parameters generally refer to the specific acoustic characteristic parameters brought by the physical characteristic parameters such as the size and shape of the home room, the materials used for the decoration of the room walls / floors / ceilings, and the furniture arrangement. In the embodiments of the present application, the environmental acoustic characteristic parameters can be obtained through the application program end APP installed on an electronic device with a microphone module and cooperating with the audio system, or through the application program end APP installed on an electronic device with a camera module and cooperating with the audio system, or through the application program end APP installed on an electronic device with a camera module and a microphone module and cooperating with the audio system to obtain the physical characteristic parameters such as the size and shape of the room, the materials used for the decoration of the room walls / floors / ceilings, and the furniture arrangement, and generate an environmental three-dimensional model. The room physical characteristic parameters can be obtained either by emitting sound waves or by computer vision, or by combining the two to obtain more accurate room physical characteristic parameters. After detecting the physical characteristic parameters of the room, they are input into acoustic simulation software, such as EASE (Enhanced Acoustic Simulator for Engineers), Odeon, CATT-Acoustic, Room EQ Wizard, SoundPLAN to calculate and obtain the acoustic characteristic parameters. In a specific implementation manner, the front end of the APP supporting the audio system receives the measured room physical characteristic parameters, and then sends these parameters to the associated acoustic simulation software through the back-end system for simulation calculation to obtain the acoustic characteristic parameters of the room.
[0017] It should be noted that after detecting the physical characteristic parameters of the room, they can either be directly input into the acoustic simulation software to obtain relatively accurate room acoustic characteristic parameters, or be acoustically processed by the processor of the electronic device to obtain relatively primary room acoustic characteristic parameters.
[0018] In a preferred embodiment, the physical characteristic parameters of the room are detected each time the device is powered on, and any changes in the position or replacement of the furniture in the room will update the acoustic characteristic parameters of the room, so as to ensure that an accurate calculation premise for the audio algorithm can be provided and a more accurate recommended placement position can be calculated.
[0019] This application uses rooms of different shapes, different sizes, and various decoration materials as test samples. During the test, furniture of different sizes and shapes is placed in the room, and the positions of various audio devices are adjusted controllably to test the influence of different placement methods on the sound effect, so as to find the placement position of the device with the best sound effect. Subsequently, a systematic analysis is carried out on these test sample data to train a deep neural network model, enabling the model to learn the complex relationship between the input parameters and the acoustic characteristics. By inputting the device characteristic parameters of the audio device and the acoustic characteristic parameters of the use environment into the trained deep neural network model, the best placement position of a specific audio system in a specific environment can be calculated, providing an optimized placement plan for the audio device for the user.
[0020] In addition, the best placement position of the audio system can also be recommended through statistical modeling methods based on room acoustic characteristic parameters and optimization search techniques. The first step is to receive data input, including but not limited to room geometric parameters: length, width, height, wall material, furniture position, etc.; audio device characteristic parameters: speaker type, power, frequency response, sound beam width, etc. In other embodiments, user requirement input can also be received, including but not limited to listening position, preferred sound effect mode (theater, music, etc.). The second step is to calculate the early reflections based on the ray tracing method to obtain the key reflection points, and calculate the low-frequency standing waves based on the modal analysis to identify the resonance frequency points. The third step is to calculate the best placement position of each speaker based on the ITU-R BS.775 standard (surround sound system) and / or Dolby Atmos recommended placement plan. The fourth step is to use the genetic algorithm to search for the optimal position, with the optimization objectives: reducing the standing wave effect, improving the sound coverage uniformity, and optimizing the sound image positioning. In addition, for the placement position of the subwoofer, calculate the low-frequency resonance mode of the room, avoid placing the subwoofer at the pressure extreme points (such as the corner, the center point), and then use the existing particle swarm optimization algorithm to calculate the best subwoofer position. Finally, output the recommended coordinates (X, Y, Z) and the recommended placement angle of each audio device in the audio system.
[0021] The present application provides a method for controlling an audio system. The audio system includes a plurality of audio transmission-connected audio devices, and the method includes: obtaining device characteristic parameters of the audio system and acoustic characteristic parameters of the environment where the audio system is located; calculating placement guidance information based on the device characteristic parameters and the acoustic characteristic parameters; outputting a graphical user interface for receiving a first user input, where the first user input is used to indicate whether the user needs placement guidance; in response to the first user input, outputting the placement guidance information or outputting the placement guidance information and a graphical user interface for receiving a second user input, where the second user input indicates whether the user has completed the placement; or in response to the first user input, returning to the current graphical user interface; after the second user input, detecting the current position of the audio system and determining whether the current position of the audio system matches the position of the audio system included in the placement guidance signal; if not, outputting the placement guidance information again or generating an audio processing algorithm based on the current position of the audio system, the device characteristic parameters, and the acoustic characteristic parameters.
[0022] Specifically, please refer to Figure 1 , which shows a schematic diagram of the interface of the application program client APP supporting the audio system. When the user opens the APP, GUI1 is first displayed. When the user clicks the "+" sign, the connection to the current audio system is shown as GUI2 (the home page of the APP). When the user operates any operation in GUI2, such as adjusting the volume, GUI3 pops up to ask the user whether they need placement guidance. It should be noted that a new graphical user interface can be popped up to ask the user whether they need placement guidance, or a small window can be popped up in the original graphical user interface to ask the user whether they need placement guidance. In addition, GUI3 can pop up when the user operates the GUI2 interface, or it can pop up immediately after the user connects to the audio system to ask the user whether they need placement guidance; in addition, when the background detects a change in the environment where the audio system is located or a change in the position of the audio device, a graphical user interface asking the user whether they need placement guidance can also be actively popped up. For example, "It is detected that the position of the audio device has changed. Do you need placement guidance?" "It is detected that the room layout has changed. Do you need placement guidance?" etc. In addition, a voice prompt can also be played synchronously when GUI3 pops up to ask the user whether they need placement guidance, further improving the user experience of the product.
[0023] If the user selects "Yes", the placement guidance information GUI4 as shown in Figure 2 will pop up. It should be noted that Figure 2 the placement guidance schematic diagram in Figure 2Exemplary static placement guidance is shown below, and dynamic placement guidance for each audio device can also be output in the graphical user interface. In one implementation, the recommended position of the audio device is displayed in a first manner, and the current position of the audio device is displayed in a second manner. For example, the current position of the audio device is displayed with a solid-line icon, and the recommended position of the audio device is displayed with a dashed-line icon.
[0024] Further, in the image user interface, the icon corresponding to the audio device not in the recommended position can also blink. For example, Figure 2 if the rear left surround 15 shown is not in the recommended position, the rear left surround 15 blinks to prompt the user to move the rear left surround 15 to the recommended position. After the user moves the rear left surround 15 to the recommended position, the icon corresponding to the rear left surround 15 stops blinking.
[0025] In addition, when the GUI3 is popped up and the user selects "no", that is, the first user input indicates that placement guidance is not required, the current graphical user interface is returned. For example, when the GUI3 is popped up at GUI2, GUI2 is returned.
[0026] After the user finishes placing according to the example guidance, in Figure 3 the GUI5 shown, the user is asked whether the placement is completed. Figure 3 The illustration below is for convenience only. The GUI5 can be integrated into the placement guidance information GUI4. That is to say, the user can refer to the GUI4 for placement and directly input the information of "completed placement" after the placement is completed. The second user input indicates whether the user has completed the placement. At this time, the background system detects whether the user's placement position meets the requirements. If so, a prompt window is popped up to prompt the user that the placement of each audio device in the audio system has been completed according to the requirements. If not, a prompt window is popped up to ask the user whether to re-place. If so, the above steps are repeated. If not, the current positions of each audio device are detected, and corresponding audio processing algorithms are generated based on the current positions of the audio devices, the device characteristic parameters of the audio system, and the acoustic characteristic parameters of the environment where they are located, and the audio signals input to the audio system are processed.
[0027] It should be noted that Figure 3 the illustration below is only one implementation manner to confirm whether the user has completed the placement, and the graphical user interface shown below may not be output either. Figure 3 For example, the current position and movement state of the audio device can be detected in real time. When the user places the audio device at the recommended position, it is regarded that the user has completed the placement. Or when the position of the audio device has not changed for more than the preset time, it is regarded as completed.
[0028] In one embodiment, when the user moves the audio device, the solid-line icon corresponding to the audio device moves on the graphical user interface. When the solid-line icon corresponding to the audio device coincides with the dashed-line icon corresponding to the recommended position, the placement of the audio device is completed.
[0029] Detect the current positions of each audio device, including but not limited to position coordinates, angles and other data in the environmental three-dimensional model. Specifically, the position and / or angle data of multiple audio devices in a stationary state can be collected through one or more of ultrasonic, infrared signals, Bluetooth, microphone array detection technology, and ultra-wideband technology; the motion trajectories and direction changes of multiple audio devices can be collected using inertial measurement technology. The fusion of multiple sensor detections can utilize the complementary advantages of different sensors to improve the accuracy, robustness, and real-time performance of audio position detection.
[0030] In one embodiment, the ultra-wideband technology and inertial measurement technology are combined to obtain the position information of each audio device. At least 4 non-coplanar signal base stations need to be arranged in space for ultra-wideband technology positioning. First, according to the environmental three-dimensional model obtained in step S102, determine the specific positions of the 4 signal base stations ( xi , yi , zi )(i = 1, 2, 3, 4). The audio device sends signals to the signal base stations or the signal base stations send signals to the audio device to measure the distance d from the audio device to each base station i , that is, the distance from the audio device to signal base station 1 is d 1、 to signal base station 2 is d 2 、 to signal base station 3 is d 3、 to signal base station 4 is d 4 . The position of the audio device (x, y, z) satisfies the following system of equations:
[0031] After expansion, it is obtained:
[0032] For signal base station 1, there is:
[0033] For signal base station i (i = 2, 3, 4), there is:
[0034] Subtract the above two equations to obtain a linear equation:
[0035] Organize the above equation into matrix form:
[0036] Solve the above equations using linear algebra methods such as Gaussian elimination or matrix inversion to obtain the coordinates (x, y, z) of the audio device.
[0037] In addition, when the audio device moves, its movement trajectory and direction changes can be monitored in real time through the inertial measurement unit installed in it. Its coordinates can be obtained in real time through calculation, thus improving the timeliness and accuracy of the audio device positioning. In another embodiment, the background system can detect the current position of the audio device in real time and compare it with the recommended position to determine whether the user has completed the placement by itself. Specifically, the background system detects the position of the audio device in real time, actively detects the moving direction of the audio device when the user moves the audio device. When the user places the audio device, for example, if it is detected that the position of the audio device has not changed for more than a preset time, such as 2 seconds, the system determines that the user has placed the audio device. The background system can quickly determine the current position of the audio device according to the original position of the audio device and the moving direction detected during the user's movement, so as to quickly determine whether the current position of the audio device meets the recommended position requirements. When it does not meet the requirements, a graphical user interface or voice prompt containing specific moving suggestions is popped up. When it meets the requirements, a prompt pop-up window indicating that the placement has been completed is popped up. It should be noted that since the audio system includes multiple audio devices, when the placement positions of each audio device do not meet the requirements, the user needs to complete the placement of all audio devices in sequence before it can be considered that the position placement has been completed.
[0038] It should be noted that the embodiments of the present application can output corresponding placement guidance information to the user through the graphical user interface of the APP; or convey the placement guidance information to the user through the audio device itself. Specifically, for example, the rear left surround 15 should be placed at a position 135° - 150° behind the left of the listening position (such as the sofa shown in the figure), but it is placed at a position 135° - 150° in front of the left of the sofa. At this time, the rear left surround 15 plays a voice prompt, such as "Please place this audio device at a position 135° - 150° behind the left of the listening position" or "Please move this audio device backward", "Please move this audio device to the left" and other voice prompt messages, so as to more directly prompt the user of the placement position of the audio device.
[0039] In addition, it should be noted that the present application provides a preferred placement guidance for audio devices. It can not only more directly and effectively prompt the user of the positions where each audio device should be placed through the graphical user interface of the APP, the voice prompt of the APP, and the voice prompt of the audio device itself, but also calculate the optimal placement positions for a specific usage environment through a deep neural network model or statistical modeling, greatly improving the user experience of the product. In other embodiments, the optimal placement positions of each audio device can also be directly calculated based on the ITU-R BS.775 standard (surround sound system) and / or the recommended placement scheme of Dolby Atmos, and then the positions where each audio device should be placed are prompted to the user through the graphical user interface and / or voice based on these placement positions.
[0040] The present application also provides another control method for an audio system, including: obtaining the device characteristic parameters of the audio system and the acoustic characteristic parameters of the environment where it is located; calculating first placement guidance information according to the device characteristic parameters and the acoustic characteristic parameters; outputting a graphical user interface for receiving a first user input, where the first user input is used to indicate whether the user needs placement guidance; in response to the first user input, outputting placement guidance information; the placement guidance information includes the first placement guidance information, and second placement guidance information generated by comparing the current positions of the audio devices with the first placement guidance information. The first placement guidance information is the recommended position corresponding to each audio device, such as the information shown in GUI4 as Figure 2 shown. The second placement guidance information is the information generated by combining the first placement guidance information with the current position, that is, the information on how to move the audio device specifically. It can show the direction and distance of the movement of the audio device in a graphical way, so as to more conveniently enable the user to move the audio device with reference to the guidance of the graphical user interface. The second placement guidance information is displayed near the icon corresponding to each audio device for the user to refer to and execute. When the real-time position of the audio device is the same as the recommended position of the audio device corresponding to the first placement guidance information, the second placement guidance information displayed near the audio device disappears. When the second placement guidance information near all audio devices disappears, a graphical user interface indicating that the placement of the audio system is completed is output. As Figure 6 shown, the second placement guidance information includes indicating the direction and distance of the movement of the corresponding audio device in a graphical way. Specifically, the movement direction can be indicated by an arrow, with the arrow pointing from the current position to the position where it should be placed, and as the user moves the audio device, the length of the arrow gradually shortens.
[0041] The present application also provides an intelligent guidance system for an audio system. The system includes: at least one processor communicatively connected to the audio system; a computer-readable medium including instructions stored thereon, which, when executed by the at least one processor, cause the at least one processor to perform the operations described above.
[0042] The present application also provides a device for guiding a user to place an audio system, including a graphical user interface provided by a client device. The graphical user interface is configured to receive a first user input for indicating whether the user needs placement guidance; in response to the first user input, output placement guidance information and a graphical user interface for receiving a second user input, where the second user input indicates whether the user has completed the placement; or in response to the first user input, return to the current graphical user interface; and output placement guidance information or return to the current graphical user interface in response to the second user input. Further, the graphical user interface is also configured to display the recommended positions of each audio device in the environment where it is located. Further, the graphical user interface is also configured to display the current positions of each audio device.
[0043] The intelligent guidance system, control method and device for an audio system provided by the present application comprehensively consider the device characteristic parameters of the audio system and the acoustic characteristic parameters of the environment where it is located, calculate reasonable placement guidance information, and provide intuitive placement guidance information through an interactive graphical user interface (GUI) or voice prompts to guide the user to optimize the placement position of the audio device, and allow the user to freely choose whether to adjust the position of the audio device, improving the user experience of the system. In addition, when the user does not place the audio device according to the recommended position, the system can optimize the audio processing based on the new device position, device characteristic parameters, and environmental acoustic characteristic parameters, so that even under non-optimal placement conditions, a better audio playback effect can be obtained, thereby enhancing the overall user experience and sound quality performance of the product.
[0044] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, or improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
