Description

Technical Field

[0002] In-car panoramic sound creates a realistic three-dimensional sound space through the collaborative work of multiple channels, making users feel as if they are in the audio scene. However, the current panoramic sound system has some limitations.

[0003] On the one hand, traditional in-car panoramic sound systems are typically optimized based on a fixed central listening position, requiring users to be in a specific position to achieve the best panoramic sound effect. For example, in a vehicle, panoramic sound characteristics such as sound positioning and surround perception can only be perfectly presented in the center position. However, in real-world scenarios, users are positioned to the left, right, left, and right of the center position, and it is difficult to fix them. They may move their bodies while watching a movie or sit in different positions at different times, which makes it impossible to always enjoy the optimal panoramic sound effect.

[0004] On the other hand, existing panoramic sound systems struggle to adapt to changes in listening position. When the user changes position, the system is unable to adjust the audio signal in time, causing deviations in the sound positioning and spatial perception, seriously affecting the quality of the panoramic sound experience.

[0005] Therefore, a vehicle sound field control solution is needed to determine the central listening position according to the actual riding situation, refresh the central listening position from time to time, and calculate the three-dimensional sound effect space based on the central listening position.

[0059] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0060] Figure 1 This is a flowchart of a vehicle sound field control method provided by one or more embodiments of the present invention.

[0061] like Figure 1 The vehicle sound field control method shown includes: the vehicle sound field control method includes:

[0062] Step S1, obtaining the working range information of the vehicle sound channel;

[0063] The vehicle's sound channel operating range information includes the spatial range in which multiple sound channels in the vehicle work in coordination, based on the central listening position set to form a three-dimensional sound effect space;

[0064] Step S2, locating the center listening position corresponding to the working range of the vehicle sound channel;

[0065] Positioning the central listening position includes identifying the spatial position of the auditory organ relative to the vehicle, and calibrating the central listening position based on the spatial position of the auditory organ relative to the vehicle;

[0066] Step S3: According to the calibrated central listening position, the sound generation strategy of the vehicle sound channel is controlled, and the calibration corresponding to the central listening position is formed to control the formation state of the three-dimensional sound effect space.

[0067] Specifically, in one embodiment, multiple sound channel devices are positioned within the vehicle, working in concert to create an effective three-dimensional sound space within the vehicle. Due to the varying locations and performance of the sound channel devices, the operating ranges of the channels vary, resulting in varying ranges within the vehicle's interior.

[0068] In this embodiment, an effective three-dimensional sound effect space is formed based on the central listening position, and the effective three-dimensional sound effect space changes with the change of the central listening position. The three-dimensional sound effect space that can be formed is delineated corresponding to the central listening position, including that the volume of the channel device decreases according to the distance from the central listening position (such as the listening position) to one of the channel devices, and then the three-dimensional sound effect space changes. In another embodiment, in addition to the channel devices in the car, channel devices at other locations in the car are also included. In addition to setting the central listening position in the car, it also includes setting the central listening position outside the car, forming an effective three-dimensional sound effect space corresponding to the central listening position outside the car, serving a kind of in-car outdoor karaoke KO scene, and using the channel devices in the car as common channel devices to participate in collaborative work to generate a three-dimensional sound effect space for the central listening position outside the car.

[0069] According to the working range of the on-board sound channels, locate the central listening position to ensure that the working range of the on-board sound channels covers the service object, that is, a certain central listening position, and the sound channels work together.

[0070] Within the operating range of the vehicle's sound channel, the corresponding auditory organs can be identified through biometric recognition technology, visual recognition technology, etc., and used as the central auditory position calibration. Auditory organs outside the operating range of the sound channel are not included in the candidate calibration objects.

[0071] According to the calibrated center listening position, the sound strategy of the sound channels in the car is controlled, and the calibration of the corresponding center listening position is formed to control the formation state of the three-dimensional sound effect space. This includes starting some sound channel devices to work together for a center listening position, including calculating and controlling the delay time, volume and phase of the sound channels, so that the three-dimensional sound effect space is formed at the calibrated center listening position.

[0072] In this embodiment, identifying the spatial position of the auditory organ relative to the vehicle includes:

[0073] Obtain biometric information in the vehicle;

[0074] Mark the location of the auditory organs based on the biometric information in the car;

[0075] It also includes obtaining the authority to locate the designated center listening position based on the biometric information in the vehicle;

[0076] According to the authority of the calibrated central listening position, the position of the auditory organ is selected to control the formation state of the three-dimensional sound space.

[0077] Specifically, in one embodiment, the seat occupants and their auditory positions are identified through visual, infrared, and / or ultrasonic recognition. Furthermore, the auditory organs of rear-row VIP passengers (relatively high-privilege passengers) are prioritized as the central listening position, with more audio channel devices activated to control the formation of a three-dimensional sound space.

[0078] One possibility cannot be ruled out. If the sound channel equipment that is closer to the driver is called to serve the VIP passengers in the back row, causing the driver to feel auditory discomfort, the sound channel equipment can be abandoned to serve the VIP passengers in the back row, that is, a three-dimensional sound space (such as a panoramic sound effect) is formed with the auditory organs of the VIP passengers in the back row as the central listening position.

[0079] In this embodiment, the sound generation strategy of the vehicle sound channel includes:

[0080] Calculating audio signal adjustment parameters of the vocal channel according to the position of the selected auditory organ;

[0081] Calculating the audio signal adjustment parameters of the channels includes calculating the delay time, volume and phase of each channel;

[0082] It also includes updating the delay time, volume and phase of each channel according to the updating of the position of the selected auditory organ.

[0083] Specifically, in this embodiment, simply identifying a passenger's position is insufficiently accurate due to factors such as height. Further identification of the auditory organ's position is required, followed by calculation of the channel's audio signal adjustment parameters. Creating a three-dimensional sound space requires the coordinated operation of multiple channel devices, necessitating calculations of the delay, volume, and phase for each channel. Because people are mobile, continuous updates to the auditory organ's position identification, and subsequently to the delay, volume, and phase for each channel, allow for continuous service to a central listening position, effectively creating a continuous three-dimensional sound space for that particular auditory organ.

[0084] In this embodiment, it also includes:

[0085] determining whether the selected auditory organ includes multiple locations;

[0086] If there are multiple ones, the delay time, volume and phase of the sound channel are set according to the position relationship between the position of the auditory organ and the sound channel;

[0087] Setting the delay time, volume and phase of the sound channel includes selecting a calibrated central listening position corresponding to the sound channel according to the distance between the position of the auditory organ and the position of the sound channel and / or the occlusion state of the sound channel.

[0088] Specifically, because multiple people can be present in a single vehicle interior, and audio channel devices may be distributed across multiple locations, some may be closer to or farther from a particular person. Multiple people can be designated as central listening positions, and audio channel devices can be grouped into these positions. When matching audio channel devices, preference is given to those closest to the central listening position and those whose sound is not obstructed by other people or objects.

[0089] Multiple sets of different sound channel devices serve different central listening positions. If there is an obstruction to the sound channel propagation, the preset central listening position can be abandoned. For example, if the front row person blocks the sound path from the front row sound channel device to the back row, the sound channel device will be abandoned to serve the back row person.

[0090] Figure 2 1 is a structural diagram of a vehicle sound field control system provided by one or more embodiments of the present invention.

[0091] like Figure 2 The vehicle sound field control system shown includes: a position detection module, an audio processing module and a control module;

[0092] A position detection module, used to identify and detect the position of the auditory organ;

[0093] Audio processing module, used to calculate the delay time, volume and phase of each channel;

[0094] A control module, used for coordinating the position detection module and the audio processing module;

[0095] The control module receives the auditory organ position data from the position detection module;

[0096] According to the auditory organ position data, the control module sends instructions to the audio processing module to calculate the delay time, volume and phase of each channel.

[0097] Specifically, the location detection module includes infrared detection to identify all passengers on the vehicle and their seats, a camera to determine if a person has priority access to the 3D sound space service, and an ultrasonic device to identify the distance between the person and the sound channel device.

[0098] The audio processing module calculates the delay time, volume and phase of each channel based on the distance data from the position detection module.

[0099] The control module coordinates the various channel devices to serve the central listening position and controls the data input to the audio processing module. For example, if the central listening position is close to a channel device, the volume of the channel device will be reduced accordingly.

[0100] In this embodiment, the control module further includes:

[0101] Generate information on the distance between the position of the auditory organ and the position of the vocal tract and / or the occlusion status of the vocal tract based on the auditory organ position data received from the position detection module;

[0102] Generate a calibrated central listening position corresponding to the selected channel based on the distance between the position of the auditory organ and the position of the vocal channel and / or information about the occlusion status of the vocal channel;

[0103] Based on the calibrated central listening position corresponding to the selected channel, an instruction is generated for the audio processing module to calculate the delay time, volume and phase of each channel.

[0104] Specifically, it is not ruled out that there are multiple people in the car, which can form multiple central listening positions and block some channel equipment. The calibrated central listening position corresponding to the selected channel can be generated based on the distance between the position of the auditory organ and the position of the channel and / or the blocked state of the channel. Then, part of the channel equipment serves one of the central listening positions, and the other part of the channel equipment serves the other central listening position.

[0105] Figure 3 1 is a structural diagram of a vehicle sound field control device provided by one or more embodiments of the present invention.

[0106] like Figure 3 The vehicle sound field control device shown includes: a sound channel working range module, a positioning center position module, and a sound effect space control module;

[0107] The sound channel working range module is used to obtain the sound channel working range information on the vehicle;

[0108] The vehicle's sound channel operating range information includes the spatial range in which multiple sound channels in the vehicle work in coordination, based on the central listening position set to form a three-dimensional sound effect space;

[0109] The center position positioning module is used to locate the center listening position corresponding to the working range of the vehicle sound channel;

[0110] Positioning the central listening position includes identifying the spatial position of the auditory organ relative to the vehicle, and calibrating the central listening position based on the spatial position of the auditory organ relative to the vehicle;

[0111] The sound space control module is used to control the sound strategy of the vehicle's sound channels according to the calibrated central listening position, form a calibration corresponding to the central listening position, and control the formation state of the three-dimensional sound space.

[0112] It is worth noting that although the present system only discloses the sound channel working range module, the positioning center position module, and the sound effect space control module, it does not mean that the present device is limited to the above-mentioned basic functional modules. Rather, what the present invention wants to express is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the existing technology to form an infinite number of embodiments or technical solutions. In other words, the present system is open rather than closed. Just because the present embodiment only discloses individual basic functional modules, it cannot be considered that the scope of protection of the claims of the present invention is limited to the above-mentioned basic functional modules.

[0113] Figure 4 It is a schematic diagram of the implementation process of a specific embodiment of the present invention.

[0114] Figure 5 It is a schematic diagram of a system framework of a specific embodiment of the present invention.

[0115] In a specific embodiment, Figure 5 The system framework shown includes: panoramic sound system.

[0116] 1. Position detection module;

[0117] Multiple onboard sensor technologies, such as infrared sensor arrays, ultrasonic sensors, and cameras, monitor the listening position in real time. The infrared sensor array detects the position and movement of the human body by transmitting and receiving infrared light. Ultrasonic sensors use the principle of ultrasonic reflection to measure the distance between the listening position and each sensor. Cameras use image recognition technology to identify the user's position and posture. These onboard sensors work together to accurately obtain the three-dimensional coordinates of the user's listening position in space.

[0118] 2. Audio processing module;

[0119] Based on the user's listening position, as determined by the position detection module, the panoramic sound signal is adjusted in real time. This module incorporates advanced audio algorithms that calculate the delay, volume, and phase adjustments for each channel's audio signal based on the relative positions of the listening position (center listening position) and the speakers of each channel. For example, if the listening position is close to the speaker of a particular channel, the volume of that channel is appropriately lowered while the volume of the other channels is increased to ensure that the sound reaches the listening position at the same time, avoiding phase distortion.

[0120] 3. Control module;

[0121] This module coordinates the work between the position detection module and the audio processing module. It receives the user's listening position information from the position detection module and passes it to the audio processing module. It also receives audio signal adjustment instructions generated by the audio processing module and controls the audio playback device to output the audio signal according to the adjusted parameters, achieving real-time adaptive adjustment of the panoramic sound effect.

[0122] In another specific embodiment, Figure 4 The implementation process shown includes:

[0123] 1. Detection of user listening position;

[0124] The various on-board sensors in the position detection module work in real time to obtain the position information of the listening position in space, including coordinate data in the X, Y, and Z axis directions.

[0125] The position detection module includes an infrared sensor array located at the front of the vehicle's roof or above the A-pillar or B-pillar. Ultrasonic sensors are installed near each speaker, and a camera is mounted on the interior rearview mirror. When a user sits in a seat, the infrared sensor array first detects the user's thermal radiation, initially determining their approximate location. The ultrasonic sensors transmit and receive ultrasonic waves to accurately measure the distance between the user and each sensor, further determining the user's three-dimensional coordinates in space. The camera uses image recognition technology to confirm and correct the user's position and posture, ensuring accurate location information. For example, the coordinated operation of these onboard sensors determines that the user's listening position is the driver's position, with coordinates (X1, Y1, Z1).

[0126] 2. Calculation of audio signal adjustment parameters;

[0127] The audio processing module combines the user's listening position information with the panoramic sound system (such as Figure 5 The system uses a speaker layout and audio algorithm (as shown in the figure) to calculate adjustment parameters such as delay, volume, and phase for each channel's audio signal. For example, based on the distance difference between the listening position and each speaker, it calculates corresponding delay adjustment values ​​to compensate for differences in sound propagation time.

[0128] The audio processing module calculates the adjustment parameters of the audio signal based on the acquired listening position coordinates (X1, Y1, Z1) and the coordinate positions of the speakers in each channel. For example, by calculating that the distance between the listening position and the front left channel speaker is d1, and the distance between the listening position and the front right channel speaker is d2, since d1 is less than d2, in order to maintain the balance of the sound, the audio processing module calculates that the front left channel speaker needs to be lowered by 3 decibels and the front right channel speaker needs to be raised by 3 decibels. At the same time, based on the difference in sound propagation distance, the delay time adjustment value of the rear channel and top channel audio signals is calculated to ensure that the sound can reach the listening position at the same time.

[0129] 3. Audio signal adjustment and output;

[0130] The control module sends instructions to the audio playback device based on the adjustment parameters calculated by the audio processing module, adjusts the parameters such as delay, volume and phase of the audio signals of each channel, and outputs the adjusted audio signals so that the panoramic sound effect can adapt to changes in the listening position in real time.

[0131] The control module receives information such as the volume adjustment value, delay adjustment value, and phase adjustment parameters for each channel's audio signal calculated by the audio processing module, and sends instructions to the audio playback device. Based on the instructions, the audio playback device makes corresponding adjustments to the audio signal of each channel, such as adjusting the volume of the front left and right channels, as well as the delay time of the rear and overhead channels. Once the adjustments are complete, the adjusted audio signal is output and played through the speakers of each channel, allowing the user to obtain the optimal panoramic sound effect at the current listening position (X1, Y1, Z1).

[0132] Through the above examples:

[0133] 1. Enhanced audio experience: Regardless of the user's position in the space, the system can adjust the panoramic sound effect in real time to ensure that the user always obtains accurate sound positioning, clear surround feeling and immersive audio experience, greatly improving the practicality of the panoramic sound system and user satisfaction.

[0134] 2. Enhanced flexibility: No longer limited to a fixed listening position, users can move freely within a certain range, such as changing their sitting position at will in the vehicle, or enjoying high-quality panoramic sound effects in different seats in the vehicle, providing users with a more flexible and free user experience.

[0135] 3. Intelligent Adaptation: The system automatically detects changes in listening position and adjusts the audio signal in real time without manual user intervention, achieving intelligent adaptive adjustment of the panoramic sound effect. It is easy to operate and improves the convenience of user experience.
