[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0060] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0061] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0062] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0063] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0064] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or a connection through a network. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0065] With the rapid development of intelligent driving technology, vehicle cabins are gradually transforming from "transportation tools" into "intelligent living spaces." Users' demands for in-vehicle acoustic environments are shifting from basic functions (such as navigation and music playback) to personalization, privacy, and multi-scenario adaptation. Drivers require clear road condition alerts and a safe driving environment, while passengers desire independent music or communication environments. Traditional acoustic systems struggle to meet these zoned requirements.

[0066] like Figure 1As shown, in large vehicles (such as buses), each seat 20 is typically equipped with a corresponding audio playback device 10, such as a speaker, for playing sound to each seat 20. All audio playback devices 10 are usually connected to the vehicle's central control or multimedia control center, which can control all audio playback devices 10 to play sound.

[0067] However, in actual car use scenarios, passengers sitting in different positions on the seats 20 in the same car have different requirements for the sound effects played by the sound playback device 10 set on their respective seats 20.

[0068] To solve the above problems, such as Figure 2 As shown, this application establishes a sound field control interface 100 on the control panel of the vehicle's central console. The sound field control interface 100 is used for human-computer interaction, allowing the driver to manage the sound effects and / or sound playback devices 10 in different areas of the vehicle through the sound field control interface 100. In the sound field control interface 100, each seat 20 corresponds to a sound playback device 10 with an icon and an icon number to distinguish the sound playback device 10 corresponding to different seats 20.

[0069] Meanwhile, the sound field control interface 100 is configured with multiple sound field regions, such as sound field region 1, sound field region 2, ..., sound field region 7, sound field region 8, etc. Each sound field region has a sound field region input box, and also includes a sound effect input box that can set unique sound effects for each sound field region. The sound effects include the type of sound being played, such as songs, white noise, silence, etc., and also includes volume control keys that can adjust the volume of each sound field region. The sound field control interface 100 manages all sound playback devices 10, allowing different sound playback devices 10 to be added to sound field regions. All sound playback devices 10 belonging to the same sound field region have the same sound effect volume.

[0070] Based on this, this application proposes a sound field control method, such as... Figure 3 As shown, it includes:

[0071] S101: In response to the fact that multiple sound playback devices in different sound field areas have the same sound effect requirements, the multiple sound playback devices are set in the same sound field area; or...

[0072] S102: In response to the different sound effect requirements of multiple sound playback devices in the same sound field area, the multiple sound playback devices are set in different sound field areas;

[0073] Among them, multiple sound playback devices in the same sound field area are suitable for playing the same sound effect.

[0074] Specifically, if different passengers on each seat 20 have the same sound effect requirements, multiple sound playback devices 10 from different sound field areas are set to the same sound field area, and sound effect requirements are set for this sound field area.

[0075] Alternatively, if the audio playback devices 10 managed in the same sound field area have different audio requirements for the passengers on the seats 20, the multiple audio playback devices 10 in this sound field area are redistributed, and set to different sound field areas according to the different audio requirements of the passengers on each seat 20, so as to ensure that each passenger can adjust in real time according to their audio requirements. Among them, the multiple audio playback devices 10 managed in the same sound field area play the same audio effects.

[0076] This application manages different audio playback devices 10 through sound field regions. Since multiple audio playback devices 10 managed in the same sound field region play the same sound effects, multiple audio playback devices 10 in different sound field regions can be set in the same sound field region in response to passengers' requests for the same sound effects; or multiple audio playback devices 10 in the same sound field region can be set in different sound field regions in response to passengers' requests for different sound effects. This satisfies the different audio needs of different passengers and can be adjusted at any time to improve the user experience.

[0077] In some embodiments, the step of placing the plurality of sound playback devices in the same sound field region includes:

[0078] Multiple sound playback devices from different sound field regions can be set in the same sound field region through a sound field control interface, wherein the sound field control interface is used for human-computer interaction.

[0079] The sound field control interface 100 is typically located on the control panel of the vehicle's central control display screen, which consists of a touchscreen LCD. The sound field control interface 100 serves as a control interface for human-machine interaction. The driver can manage the sound field area of ​​the audio playback device 10 through the sound field control interface 100.

[0080] like Figure 4 As shown, the driver can use the sound field control interface 100 to set multiple sound playback devices 10 in different sound field areas to the same sound field area. Since the same sound field area has the same sound effect, it can simultaneously manage the sound playback devices 10 that have the same sound effect requirements.

[0081] In some embodiments, the step of setting multiple sound playback devices from different sound field regions within the same sound field region via a sound field control interface includes:

[0082] Enter the first icon and the second icon in the sound field input box within the same sound field region; or

[0083] Set the first icon and the second icon to the same attribute parameter, the attribute parameter including at least one of color, shape and number;

[0084] The first icon is used to represent the first sound playback device, and the second icon is used to represent the second sound playback device.

[0085] Optionally, the sound field control interface 100 includes a sound field input box for managing the sound playback devices 10. Each sound playback device 10 has a corresponding icon on the sound field control interface 100. Typically, different sound playback devices 10 have different icons, and each icon has corresponding attribute parameters. These attribute parameters include at least one of the following: the color, shape, and number of the icon corresponding to the sound playback device 10, and usually consist of multiple of these. Therefore, multiple sound playback devices 10 from different sound field areas can be set in the same sound field area through the sound field control interface 100. This can be done by directly inputting or dragging the icons of multiple sound playback devices 10 into the sound field input box of the same sound field area, or by setting the attribute parameters of the icons of different sound playback devices 10 to the same attribute parameter, thereby managing the sound playback devices 10 uniformly through the sound field area management attribute parameters.

[0086] For example, the sound playback device 10 includes a first sound playback device and a second sound playback device. The first and second sound playback devices have different sound effects. The icon corresponding to the first sound playback device is a first icon, and the icon corresponding to the second sound playback device is a second icon. The attribute parameters of the first and second icons are different, such as the first icon having the number 1 and the second icon having the number 2, and / or the first icon being green and the second icon being red, and / or the first icon having a heart shape and the second icon having a triangle shape. In the sound field control interface 100, setting the first and second sound playback devices in the same sound field area can be done in the following ways: The first and second icons can be dragged or entered simultaneously into the sound field input box of the same sound field area, such as entering the numbers 1 and 2 into the sound field input box of the same sound field area; or, the numbers of the first and second icons can be set to 1 simultaneously, and / or the colors of the first and second icons can be set to green simultaneously, and / or the shapes of the first and second icons can be set to hearts simultaneously, and then the numbers of each sound playback device managed by the sound field area can be set to 1, and / or the color of the icons can be set to green, and / or the shape of the icons can be set to hearts. This allows the first and second sound playback devices to be managed within the same sound field area.

[0087] In some embodiments, the step of positioning the plurality of sound playback devices in different sound field regions includes:

[0088] Multiple sound playback devices in the same sound field area can be set in different sound field areas through the sound field control interface, which is used for human-computer interaction.

[0089] Optionally, if multiple sound playback devices 10 managed within the same sound field area require different sound effects from corresponding passengers, the sound field control interface 100 can be used to set the multiple sound playback devices 10 in the same sound field area to different sound field areas. The sound field control interface 100 is used for human-computer interaction. The driver can use the sound field control interface 100 to remove multiple sound playback devices 10 in the same sound field area from the sound field input box by deleting or dragging icons, and to place the multiple sound playback devices 10 into the sound field input boxes corresponding to different sound field areas for management, so as to meet the different sound effect requirements of different passengers.

[0090] In some embodiments, the different sound field regions include a first sound field region and a second sound field region, and the step of setting multiple sound playback devices in the same sound field region in the different sound field regions through a sound field control interface includes:

[0091] Enter the first icon in the sound field input box of the first sound field region, and enter the second icon in the sound field input box of the second sound field region; or

[0092] The first icon and the second icon are set with different attribute parameters, the attribute parameters including at least one of color, shape and number;

[0093] The first icon is used to represent the first sound playback device, and the second icon is used to represent the second sound playback device.

[0094] Similarly, multiple sound playback devices 10 in the same sound field area can be set to different sound field areas through the sound field control interface 100, including: deleting or removing icons of multiple sound playback devices 10 in the same sound field area from the sound field input box, or changing the attribute parameters corresponding to multiple sound playback devices 10, and then moving multiple sound playback devices 10 to different sound field areas, or setting the attribute parameters of the icons corresponding to the sound playback devices 10 to the icon attribute parameters managed by different sound field areas.

[0095] For example, different sound field regions include a first sound field region and a second sound field region. Within the sound field control interface 100, multiple sound playback devices 10 within the same sound field region need to be set to the first sound field region and the second sound field region respectively. The first sound field region includes a first sound field input box, and the second sound field region includes a second sound field input box. The multiple sound playback devices within the same sound field region include a first sound playback device and a second sound playback device. The first sound playback device and the second sound playback device have different sound effect requirements. The icon corresponding to the first sound playback device is a first icon, and the icon corresponding to the second sound playback device is a second icon. The attribute parameters of the first icon and the second icon are different.

[0096] At this time, the first sound playback device and the second sound playback device can be set in different sound field areas by entering the first icon in the first sound field input box in the first sound field area and the second icon in the first sound field input box in the second sound field area through the sound field control interface 100.

[0097] Alternatively, through the sound field control interface 100, the attribute parameters of the icon for the sound playback device 10 managed by the first sound field area can be set to include a number of 1, and / or a red color, and / or a triangle shape; the attribute parameters of the icon for the sound playback device 10 managed by the second sound field area can be set to include a number of 2, and / or a green color, and / or a quadrilateral shape. By directly setting the attribute parameters of the icon corresponding to the first sound playback device to a number of 1, and / or a red color, and / or a triangle shape, the first sound playback device can be set to the first sound field area; similarly, by directly setting the attribute parameters of the icon corresponding to the second sound playback device to a number of 2, and / or a green color, and / or a quadrilateral shape, the second sound playback device can be set to the second sound field area.

[0098] In some embodiments, the method further includes: setting the sound effects of the sound field region according to the sound effect requirements corresponding to the sound field region.

[0099] Optionally, the sound effects of the sound field area can be controlled and set within the sound field control interface 100 according to the sound effect requirements of the passengers corresponding to the sound playback device 10 managed by the sound field area.

[0100] In some embodiments, setting the sound effects of the sound field region according to the sound effect requirements corresponding to the sound field region includes:

[0101] According to the sound effect requirements corresponding to the sound field area, set the sound effect parameters in the sound effect input box of the sound field area, and the sound effect parameters include at least the sound effect type;

[0102] The sound effect input box corresponds one-to-one with the sound field input box of the sound field area.

[0103] Optionally, the sound field area also includes sound effect input boxes, with each sound field area corresponding to a sound effect input box. Based on the corresponding sound effect requirements, the sound effect parameters for the sound field area are set in the sound effect input boxes. These sound effect parameters include at least the sound effect type. The sound effect input boxes can set the sound effect type for the sound field area, including various types such as silent, song, white noise, and instrumental music, and can also be customized by the user.

[0104] In some embodiments, setting the sound effects of the sound field region according to the sound effect requirements corresponding to the sound field region includes:

[0105] Set the volume of the sound field area.

[0106] Meanwhile, the volume of the sound field area can also be set. In the sound field control interface 100, each sound field area also has a corresponding volume adjustment key. The volume adjustment key of this application can be used to set the volume of the sound playback device 10 managed by the sound field area by dragging the volume indicator key left and right. After the volume is set, the volume of the sound playback device 10 managed by the same sound field area is the same.

[0107] In some embodiments, the method further includes: controlling the sound playback device in the sound field region to play sound according to the sound effect;

[0108] Based on the sound information of the sound field region, adjust the sound effects of the sound field region.

[0109] Optionally, the method of this application can also control all sound playback devices 10 in the sound field area to play sounds related to the set sound effects. Sound playback devices 10 managed within the sound field input box of the same sound field area can play the sounds of the sound effects set for the sound field area. Simultaneously, the sound effects of the sound field area can be adjusted based on the sound information of the sound field area. For example, the volume of the sound field area can be adjusted using volume control keys, or the type of sound played in the sound field area can be changed using the content in the sound effect input box.

[0110] In some embodiments, the sound playback device that controls the sound field region plays sound according to the sound effect, including:

[0111] Send a control signal to the sound playback device to control the sound playback signal to play sound according to the sound effect.

[0112] like Figure 5As shown, the sound field area includes sound playback devices 10. Inside the vehicle, above each seat 20, a corresponding sound playback device 10 is installed on the vehicle roof panel. Playback control signals can be sent from the sound field area to the corresponding sound playback device 10 to control the playback of sound effects. For example, after setting the sound effects in the sound field area, a playback control signal can be sent to the sound playback device 10 to play the set sound effects. Alternatively, after setting the volume of the sound field area, the volume of the sound playback device 10 can be adjusted using the volume control buttons.

[0113] like Figure 6 As shown, the sound playback device 10 also includes a first motor 11 and a second motor 12. The first motor 11 and the second motor 12 are connected, and the second motor 12 is connected to the speaker 13. The first motor 11 and the second motor 12 of the sound playback device 10 can also be controlled to move together through the sound field area. The first motor 11 can drive the second motor 12 to move, and the second motor 12 drives the speaker 13 to move together, so as to control the sound playback device 10 to rotate 360 ​​degrees horizontally and vertically, thereby increasing the directivity of the sound waves and reducing the reverberation phenomenon between different sound field areas.

[0114] In some embodiments, the sound field region includes a sound acquisition device, and adjusting the sound effects of the sound field region based on the sound information of the sound field region includes:

[0115] The sound information of the sound field area is acquired through the sound acquisition device;

[0116] If the sound information does not meet the corresponding sound effect requirements, adjust the sound effect parameters in the sound effect input box of the sound field area; the sound effect input box corresponds one-to-one with the sound field input box.

[0117] The sound field area includes the sound acquisition device 30, in Figure 5 In this system, each seat 20 has a sound acquisition device 30 on its headrest. The installation position is based on the position of the passenger's head. Typically, the sound playback device 10 is located at the top of the seat 20, and the sound acquisition device 30 is located on the back or headrest of the seat 20.

[0118] The sound acquisition device 30 includes a microphone array, which consists of a group of two microphones. The microphone array is used to acquire audio from the sound playback device 10. Depending on the driver's selection of different sound field areas, the audio is fed back to the controller. The controller obtains the sound information of the sound field area through the sound acquisition device 30. If the sound information does not meet the corresponding sound effect requirements, the controller adjusts the sound effect parameters in the sound effect input box of the corresponding sound field area and resets the sound effect type to match the sound effect requirements; or, the controller adjusts the volume of the corresponding sound field area.

[0119] In some embodiments, the method further includes:

[0120] Send an adjustment signal to the sound playback device to adjust the sound effect of the sound playback signal;

[0121] The adjustment signal includes the playback volume of the sound playback device, and / or the direction of the sound playback device, and / or the angle of the sound playback device.

[0122] Optionally, sound information of the sound field area can be acquired through the sound acquisition device 30 and sent to the controller. The controller can then adjust the volume using the volume control buttons within the sound field area to ensure the sound played in the sound field area meets the sound effects requirements. The controller can also control the first motor 11 and second motor 12 of each sound playback device 10 in the sound field area to adjust the direction and angle of the sound acquisition device 30, thereby changing the directivity of the sound from the sound acquisition device 30. This optimizes the division of the sound field area and improves its adaptability and robustness.

[0123] In some embodiments, after acquiring the sound information of the sound field region through the sound acquisition device, the method further includes:

[0124] The sound information is processed by an algorithm to determine whether the sound information meets the corresponding sound effect requirements.

[0125] Optionally, after the sound acquisition device 30 acquires the sound information of the sound field area, the controller uses a set algorithm to calculate whether the sound information of each sound field area meets the corresponding sound effect requirements. If the corresponding sound effect requirements cannot be met, the set algorithm can be used to analyze the sound information and determine how to adjust the information of the sound field area so that the sound information can meet the passengers' sound effect requirements for the sound field area.

[0126] In some embodiments, the setting algorithm includes boundary sound parameters of the sound field region, and the processing of the sound information through the setting algorithm includes:

[0127] The sound effect of the sound field region is calculated based on the boundary sound parameters of the sound field region, and the boundary sound parameters are used to characterize the sound information within the set boundary range of the sound field region.

[0128] The driver can also freely divide the in-vehicle sound field into zones according to the different needs of passengers. After the zones are divided, the controller controls the sound playback devices 10 in different sound field zones to play different sounds. At the same time, the sound acquisition devices 30 on the headrests collect audio data and transmit it to the controller. The controller optimizes the data through a transfer function and controls the first motor 11 and the second motor 12 of the sound playback devices 10 to rotate the sound playback devices 10 in different directions and angles. This adjusts the direction of the sound playback devices 10 to a suitable position, minimizing interference between the various sound playback devices 10, meeting the different sound effect needs of passengers, and achieving the best sound effect in the sound field zone.

[0129] Specifically, the setting algorithm includes boundary sound parameters of the sound field region. These boundary sound parameters represent the sound information within the defined boundary range of the sound field region. The controller calculates the sound effect of the sound field region based on these boundary sound parameters. The sound acquisition device 30 returns the acquired data to the controller, which analyzes and optimizes the sound wave data based on the boundary sound parameters using the setting algorithm. The setting algorithm may include a transfer function algorithm. This algorithm calculates the optimal regional effect for the sound field region division based on the boundary sound parameters. It also calculates the mixing effect of the wavelength of the sound wave data and the boundary sounds of the sound field region using the least squares method. Then, based on the wavelength of the sound wave data and the mixing effect of the boundary sounds of the sound field region, the controller intelligently and automatically adjusts the direction and volume of the sound playback device 10 to minimize audio interference at the critical points and achieve the best sound effect in that region.

[0130] In some embodiments, the method includes: obtaining the passenger's audio effect requirements for the audio playback device corresponding to the target seat.

[0131] Optionally, the sound acquisition device 30 for the target seat can be used to obtain the passenger's sound effect requirements for the target seat, and then send the sound effect requirements to the controller. The controller will set the sound playback device 10 corresponding to the target seat according to the passenger's sound effect requirements to adapt to the passenger's sound effect requirements.

[0132] In some embodiments, the method further includes: inputting the passenger's sound effect requirements for the target seat through a sound field control interface.

[0133] Optionally, after receiving the passenger's audio requirements for the target seat, the controller can set the audio parameters for different audio fields and adjust the volume through the sound field control interface 100.

[0134] For example, the sound playback device 10 corresponding to the target seat can be set to the same sound field area as the passenger's required sound effect, or the sound field area can be set with mirror sound effect parameters, volume can be adjusted, or the motor of the sound playback device 10 can be controlled to adjust the direction and angle of the sound playback device 10, thereby meeting the passenger's different needs for sound effects.
