[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on July 7, 2023, with application number 202310838551.4 and invention name “Sound system, control method and vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of smart cockpits, and more particularly, to a sound generation system, a control method, and a vehicle. Background Art

[0003] The in-car audio system generally consists of an amplifier and speakers. The functions of the amplifier include power amplification and digital signal processing (DSP). The speakers receive the processed audio signals through wired or wireless transmission and reproduce the sound. When designing a car model, the OEM usually determines the configuration of the in-car audio system, such as the model of the amplifier, the number and position of the speakers, etc., so that it is produced according to a fixed configuration and connection during manufacturing. This will solidify the design of the in-car audio system installed when the vehicle leaves the factory, making it difficult for users to modify the in-car audio system.

[0004] Summary of the Invention

[0005] The present application provides a sound system, a control method and a vehicle, which help to improve the flexibility of the sound system design, facilitate users to modify the sound system, and help improve the user experience.

[0006] In the first aspect, the present application provides a sound-emitting system, which includes: N terminal units, each of the N terminal units includes a communication module and a sound-emitting device, and N is a positive integer; M preset interfaces, each of the M preset interfaces includes a power supply interface and / or a communication interface, the power supply interface is used to power the terminal unit, and the communication interface is used to send signaling and / or data to the terminal unit through the communication module, and M is a positive integer and M is greater than or equal to N.

[0007] Based on the above technical solution, by designing N terminal units and M preset interfaces in the sound system, the terminal units can be flexibly connected to the preset interfaces, which is convenient for users to flexibly design the position or number of terminal units, thereby creating different sound environments for users; at the same time, it is also convenient for users to modify the sound system, which helps to improve the user experience.

[0008] In some possible implementations, the terminal unit may be an in-vehicle audio device, and the preset interface may be a vehicle body interface. In this case, the sound system may be an in-vehicle audio system.

[0009] Exemplarily, the vehicle-mounted audio device may be a speaker or a sound box.

[0010] The in-vehicle audio system may include: N in-vehicle audio devices, each of the N in-vehicle audio devices includes a communication module, where N is a positive integer; M vehicle body interfaces, each of the M vehicle body interfaces includes a power supply interface and / or a communication interface, the power supply interface is used to supply power to the in-vehicle audio device, and the communication interface is used to send signaling and / or data to the in-vehicle audio device through the communication module, where M is a positive integer and is greater than or equal to N.

[0011] Based on this technical solution, by designing M vehicle body interfaces, N in-car audio devices can be flexibly connected to the vehicle body interfaces. This allows users to flexibly design the location and number of in-car audio devices within the cabin, thereby creating different sound environments for users. It also allows users to easily modify the in-car audio system within the cabin, helping to improve the user experience. For vehicle manufacturers, it also allows them to equip the same model with different sound systems, streamlining their production processes.

[0012] In combination with the first aspect, in certain implementations of the first aspect, the N in-vehicle audio devices include a first in-vehicle audio device, and the first in-vehicle audio device includes an active noise reduction controller, which is used to receive first audio data from a microphone and perform noise reduction processing on the first audio data.

[0013] Based on the above technical solution, by adding an active noise reduction controller to the first in-vehicle audio device to perform noise reduction processing on the audio data from the microphone, the flexibility of the in-vehicle audio device design is improved, allowing the in-vehicle audio device to perform active noise reduction in addition to sound generation. Furthermore, this design approach eliminates the need for a connection between the processor and the active noise reduction controller. Audio data acquired by the in-vehicle audio device via the communication module can be sent to the active noise reduction controller for active noise reduction, helping to reduce wiring within the vehicle. Furthermore, a locally closed-loop active noise reduction system can be formed, which helps improve the effectiveness of local active noise reduction.

[0014] In combination with the first aspect, in certain implementations of the first aspect, the N in-vehicle audio devices include a second in-vehicle audio device, the second in-vehicle audio device includes the microphone, and the second in-vehicle audio device is used to send the first audio data to the communication module corresponding to the first in-vehicle audio device through the communication module corresponding to the second in-vehicle audio device.

[0015] Based on the above technical solution, the active noise reduction controller and the microphone can be located in different in-vehicle audio devices, so that the active noise reduction function can be realized through communication between different in-vehicle audio devices in the in-vehicle audio system, which helps to improve the flexibility of the in-vehicle audio system design.

[0016] For example, in-car audio device 1 (including an active noise reduction controller) and in-car audio device 2 (including a microphone) are located in the passenger compartment. In this way, in-car audio device 2 can transmit the audio data picked up by the microphone to in-car audio device 1, so that in-car audio device 1 can perform active noise reduction on the audio data picked up by the microphone via the active noise reduction controller. In this way, a closed-loop active noise reduction system can be implemented in the passenger compartment using in-car audio device 1 and in-car audio device 2.

[0017] In combination with the first aspect, in some implementations of the first aspect, the first in-vehicle audio device includes the microphone.

[0018] Based on the above technical solution, the active noise reduction controller and the microphone can be located in the same in-vehicle audio device, so that the active noise reduction function can be achieved through one in-vehicle audio device.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the N in-vehicle audio devices include a third in-vehicle audio device, and the third in-vehicle audio device includes a in-vehicle lighting controller, which is used to receive second audio data from a communication module corresponding to the third in-vehicle audio device; and control the operation of the in-vehicle lighting according to the second audio data.

[0020] In some possible implementations, the vehicle-mounted lamp may include an exterior decorative lamp, an interior ambient lamp, a spotlight, or a light-emitting diode (LED) lighting lamp.

[0021] Ambient lighting, also known as ambient lighting, is typically placed on a vehicle's steering wheel, center console, footlights, cup holders, roof, front lights, front sills, doors, trunk, and headlights. Ambient lighting can be monochrome, multi-color, rhythmic, or musical. It creates a sense of home warmth and comfort, while also imbuing the space with a sense of technological sophistication and luxury.

[0022] Exterior decorative lights generally include turn signals, brake lights, fog lights, headlights, width lights, roof lights, license plate lights, chassis, wheel lights, etc.

[0023] Exemplarily, when the vehicle-mounted lamp is an interior ambient light, the vehicle-mounted lamp controller may be an ambient light controller.

[0024] Based on the above technical solution, by adding an onboard lighting controller to the in-vehicle audio device, the communication module can send the received audio data to the onboard lighting controller to achieve control of the in-vehicle lighting. This helps to improve the flexibility of the in-vehicle audio device design, allowing the in-vehicle audio device to realize the function of controlling the in-vehicle lighting in addition to realizing sound. At the same time, this design approach does not require a connection relationship between the processor (for example, the central system) and the in-vehicle lighting controller, which helps to reduce the wiring inside the vehicle. In addition, directly integrating the in-vehicle lighting controller into the in-vehicle audio device helps to reduce the delay of data transmission and can improve the timeliness of the in-vehicle lighting to the rhythm of the music.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the sound system is located in a vehicle, and the vehicle lighting controller is used to control the vehicle lighting in a first area of ​​the vehicle based on the second audio data, where the first area is the area corresponding to the third vehicle audio device.

[0026] Based on the above technical solution, the communication module in the third in-vehicle audio device can send the received audio data to the in-vehicle lamp controller to control the in-vehicle lamps in the area corresponding to the third in-vehicle audio device.

[0027] The first area may be the area where the third in-vehicle audio device is located; or the first area may be different from the area where the third in-vehicle audio device is located. For example, the first area is the second row area, and the third in-vehicle audio device is located in the main driver's seat area.

[0028] Exemplarily, the vehicle may be a vehicle.

[0029] In combination with the first aspect, in certain implementations of the first aspect, the N in-vehicle audio devices include a fourth in-vehicle audio device, and the fourth in-vehicle audio device is further used to send the audio host capability and / or location information of the fourth in-vehicle audio device to the processor through the communication module corresponding to the fourth in-vehicle audio device.

[0030] Based on the above technical solution, the in-vehicle audio device can send its audio sink capabilities and / or location information to the processor, so that the processor can tune the audio according to the audio sink capabilities and / or location information of each in-vehicle audio device, without the need for manual tuning by the user. This helps to improve the intelligence level of the vehicle and also helps to enhance the user's listening experience.

[0031] In some possible implementations, the audio host capability includes information about the maximum volume of the in-vehicle audio device, frequency information of the emitted sound (for example, high frequency, medium frequency, or low frequency), and information indicating the bandwidth supported by the speakers, controller, and communication module in the in-vehicle audio device.

[0032] In combination with the first aspect, in some implementations of the first aspect, the N in-vehicle audio devices include a fifth in-vehicle audio device, and the fifth in-vehicle audio device includes a power amplifier module.

[0033] Based on the above technical solution, the in-vehicle audio system can also include an amplifier module. Audio data acquired from a terminal device such as the internet or a mobile phone can be directly transmitted to the in-vehicle audio system's communication module, which then sends it to the amplifier module for processing. The processed audio data is then played back through the in-vehicle audio system. This helps increase the flexibility of in-vehicle audio system design.

[0034] In combination with the first aspect, in some implementations of the first aspect, the N in-vehicle audio devices include a sixth in-vehicle audio device, and the sixth in-vehicle audio device includes a digital signal processing (DSP) module.

[0035] Based on the above technical solution, the in-vehicle audio system can also include a DSP module. Audio data obtained from the internet or mobile phones can be directly transmitted to the in-vehicle audio system's communication module, which then sends it to the DSP module for processing. The processed audio data is ultimately played back through the in-vehicle audio system. This helps increase the flexibility of in-vehicle audio system design.

[0036] In a second aspect, the present application provides a control method, comprising: obtaining audio sink capabilities and location information of one or more in-vehicle audio devices; determining a first tuning parameter based on the audio sink capabilities and location information of the one or more in-vehicle audio devices; and controlling the operation of the one or more in-vehicle audio devices based on the first tuning parameter.

[0037] Based on the above technical solution, by obtaining the audio sink capabilities and location information of one or more in-vehicle audio devices, tuning parameters can be determined and then used to control the operation of one or more in-vehicle audio devices. This eliminates the need for user interaction throughout the tuning process, enhancing the vehicle's intelligence and improving the user's listening experience.

[0038] In conjunction with the second aspect, in certain implementations of the second aspect, determining the first tuning parameter based on the audio sink capabilities and location information of the one or more in-vehicle audio devices includes determining the first tuning parameter based on the user's location information, the user's ear height, and the audio sink capabilities and location information of the one or more in-vehicle audio devices.

[0039] Based on the above technical solution, the user's three-dimensional coordinates can also be combined when determining the tuning parameters, so that the user can feel a better audio effect and help improve the user's listening experience.

[0040] In some possible implementations, the method further includes: obtaining location information of the user and the ear height of the user.

[0041] For example, the user's location and the height of the user's ears can be determined through data collected by sensors in the cabin (for example, a camera, a lidar, or a millimeter-wave radar, etc.).

[0042] For example, the user's location can be determined by data collected by a microphone and the user's ear height can be determined by data collected by sensors in the cabin (e.g., a camera, a lidar, or a millimeter-wave radar, etc.).

[0043] For example, the user's position can be determined by data collected by a pressure sensor on the seat, and the user's ear height can be determined by data collected by sensors in the cabin (e.g., cameras, lidar, or millimeter-wave radar, etc.).

[0044] In conjunction with the second aspect, in certain implementations of the second aspect, the location information indicates that the user is located at a first location, and before controlling the one or more in-vehicle audio devices to operate according to the first tuning parameters, the method further includes: controlling the one or more in-vehicle audio devices to emit audio data according to the first tuning parameters; and determining whether a difference in fit between a frequency response curve of sound at the first location and a preset curve is within a preset range.

[0045] Based on the above technical solution, after the tuning parameters are determined, audio data can be emitted based on them. When the difference between the frequency response curve of the sound at the user's location and the preset curve is within a preset range, the tuning process can be terminated and the final tuning parameters can be output. This allows the vehicle to achieve automatic tuning without user interaction, helping to avoid tedious user operations during the tuning process, improving the vehicle's intelligence level, and enhancing the user experience.

[0046] In combination with the second aspect, in certain implementations of the second aspect, determining the first tuning parameter based on the audio sink capabilities and location information of the one or more in-vehicle audio devices includes: obtaining a second tuning parameter; inputting the second tuning parameter and the audio sink capabilities and location information of the one or more in-vehicle audio devices into a prediction model to obtain the first tuning parameter, where the prediction model includes a three-dimensional cabin model and / or a sound wave propagation model.

[0047] Based on the above technical solution, the second tuning parameter, the audio sink capability, and the location information of the in-vehicle audio device can be input into the prediction model to obtain the final tuning parameter. This can improve the generalization and accuracy of the tuning process.

[0048] The above three-dimensional cockpit model can be determined by the positional relationship of each component in the cockpit and the interior parameters.

[0049] The above sound wave propagation model can be determined by interior parameters and frequency characteristics of sound waves (for example, reflection characteristics, diffraction characteristics, and refraction characteristics, etc.).

[0050] In conjunction with the second aspect, in certain implementations of the second aspect, determining the first tuning parameter based on the audio sink capabilities and location information of the one or more in-vehicle audio devices includes: determining the first tuning parameter based on the audio sink capabilities and location information of the one or more in-vehicle audio devices and a mapping relationship; wherein the mapping relationship is a mapping relationship between the audio sink capabilities of the in-vehicle audio devices, the locations of the in-vehicle audio devices, and the tuning parameters.

[0051] Based on the above technical solution, a vehicle can preset a mapping relationship between the audio sink capabilities, the location of the in-vehicle audio device, and the tuning parameters. Then, after the in-vehicle audio device sends the audio sink capabilities and location information to the processor, the processor can use this mapping relationship to determine the appropriate tuning parameters. This allows the vehicle to automatically tune without user interaction, helping to avoid tedious user operations during the tuning process, improving the vehicle's intelligence, and enhancing the user experience.

[0052] In combination with the second aspect, in certain implementations of the second aspect, determining the first tuning parameter based on the audio sink capabilities, location information, and mapping relationship of the one or more in-vehicle audio devices includes: determining multiple tuning parameters based on the audio sink capabilities, location information, and mapping relationship of the one or more in-vehicle audio devices; and determining the first tuning parameter from the multiple tuning parameters based on the user's physiological characteristic information.

[0053] In conjunction with the second aspect, in certain implementations of the second aspect, obtaining the audio sink capabilities and location information of one or more in-vehicle audio devices includes: upon detecting a change in the location and / or number of the one or more in-vehicle audio devices, receiving the changed audio sink capabilities and location information of the one or more in-vehicle audio devices.

[0054] Based on the above technical solution, when the location and / or number of in-vehicle audio devices changes, the processor can receive the audio sink capabilities and location information of one or more of the in-vehicle audio devices after the change in location and / or number. This allows the processor to re-determine tuning parameters based on the audio sink capabilities and location information of the updated in-vehicle audio devices. This helps improve the vehicle's intelligence and enhance the user's listening experience.

[0094] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0096] As mentioned earlier, current OEMs typically determine the configuration of the in-car audio system when designing a vehicle model, such as the amplifier model, number and location of speakers, and so on. This then leads to fixed configurations and connections during manufacturing. This results in a rigid design for the in-car audio system installed at the factory, making it difficult for users to modify the system.

[0097] The present application provides a sound system, a control method and a vehicle, which help to improve the flexibility of the sound system design, facilitate users to modify the sound system, and help improve the user experience.

[0098] Figure 1 is a schematic block diagram of a sound system 100 provided in an embodiment of the present application. The sound system 100 includes N terminal units (e.g., terminal units 1-N) and M preset interfaces (e.g., preset interfaces 1-M), where N and M are positive integers and M is greater than or equal to N. Each of the N terminal units includes a communication module and a sound device. Each of the M preset interfaces includes a power interface and / or a communication interface, the power interface being used to power the terminal unit and the communication interface being used to send signaling and / or data to the terminal unit via the communication module.

[0099] In one embodiment, the preset interface may include a power supply interface but not a communication interface. In this case, the power supply interface can supply power to the communication module in the terminal unit. For example, if the sound-emitting device is a speaker, and the speaker is an active speaker, the power supply unit can also be used to supply power to the active speaker. The communication module of the terminal unit can receive audio data wirelessly, and then play the audio data through the sound-emitting device.

[0100] In one embodiment, the preset interface may include a communication interface but not a power supply interface. For example, if the communication module in the terminal unit is a communication interface, the communication module of the terminal unit and the communication interface in the preset interface are connected via a wired connection. For example, if the sound-emitting device is a passive speaker, the communication module of the terminal unit can receive audio data sent by the communication interface, thereby playing the audio data through the passive speaker.

[0101] In one embodiment, the preset interface may include a communication interface and a power supply interface. For example, if the communication module in the terminal unit is a communication interface, the communication module of the terminal unit and the communication interface in the preset interface are connected via a wired connection. For example, if the sound-emitting device is an active speaker, the power supply interface can power the active speaker. The communication module of the terminal unit can receive audio data sent by the communication interface, thereby playing the audio data through the active speaker.

[0102] When the above terminal unit 100 is located in a home scene, the terminal unit 100 can be located in different locations in the home.

[0103] For example, Figure 2 shows a schematic diagram of the sound system in an embodiment of the present application when it is applied in a smart home scenario. Taking the terminal unit as a smart speaker (the smart speaker includes a communication module) as an example, the living room may include preset interface 1, preset interface 2, preset interface 3 and preset interface 4, wherein smart speaker 1 can be connected to preset interface 1, smart speaker 2 can be connected to preset interface 2, smart speaker 3 can be connected to preset interface 3, and smart speaker 4 can be connected to preset interface 4. The smart screen can send audio data to the communication modules of smart speakers 1 to 4 respectively, so that smart speakers 1 to 4 can create surround sound in the living room.

[0104] When the terminal unit 100 is located in a vehicle, the terminal unit 100 may be a vehicle-mounted audio device (eg, a vehicle-mounted speaker or a vehicle-mounted sound box).

[0105] The vehicles involved in the embodiments of the present application are vehicles in a broad sense, which can be transportation vehicles (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawn mowers, harvesters, etc.), amusement equipment, toy vehicles, etc. The embodiments of the present application do not specifically limit the type of vehicles.

[0106] For example, FIG3 shows a schematic block diagram of an in-vehicle audio system 300 provided in an embodiment of the present application. The in-vehicle audio system 300 may include: N in-vehicle audio devices (e.g., in-vehicle audio devices 1-N), each of the N in-vehicle audio devices including a communication module, where N is a positive integer; and M vehicle body interfaces (e.g., vehicle body interfaces 1-M), each of the M vehicle body interfaces including a power supply interface and / or a communication interface, the power supply interface being used to supply power to the in-vehicle audio device, and the communication interface being used to send signaling and / or data to the in-vehicle audio device via the communication module, where M is a positive integer and is greater than or equal to N.

[0107] Figure 4 shows a schematic diagram of the in-vehicle audio system provided by an embodiment of the present application. As shown in Figure 4, the vehicle includes body interfaces 1-12 and in-vehicle speakers 1-8. Among them, body interfaces 1-3, in-vehicle speakers 1 and in-vehicle speakers 2 can be located in the main driving area, body interfaces 4-6, in-vehicle speakers 3 and in-vehicle speakers 4 can be located in the co-pilot area, body interfaces 7-9, in-vehicle speakers 5 and in-vehicle speakers 6 can be located in the second row left area, and body interfaces 10-12, in-vehicle speakers 7 and in-vehicle speakers 8 can be located in the second row right area. In-vehicle speaker 1 is connected to body interface 1, in-vehicle speaker 2 is connected to body interface 2, in-vehicle speaker 3 is connected to body interface 4, in-vehicle speaker 4 is connected to body interface 5, in-vehicle speaker 5 is connected to body interface 7, in-vehicle speaker 6 is connected to body interface 8, in-vehicle speaker 7 is connected to body interface 10, and in-vehicle speaker 8 is connected to body interface 11.

[0108] FIG5 shows another schematic diagram of the in-vehicle audio system provided by an embodiment of the present application. The networking mode of the in-vehicle audio system is a star-shaped networking mode. The central system and each in-vehicle speaker can be connected via an audio cable.

[0109] FIG6 shows another schematic diagram of the in-vehicle audio system provided by an embodiment of the present application. The in-vehicle audio system is networked in a daisy chain configuration. The central system and in-vehicle speaker 1, in-vehicle speaker 1 and in-vehicle speaker 3, in-vehicle speaker 3 and in-vehicle speaker 4, in-vehicle speaker 4 and in-vehicle speaker 7, in-vehicle speaker 7 and in-vehicle speaker 8, in-vehicle speaker 8 and in-vehicle speaker 6, in-vehicle speaker 6 and in-vehicle speaker 5, and in-vehicle speaker 5 and in-vehicle speaker 2 can be connected via an A2B audio bus.

[0110] FIG7 shows another schematic diagram of the in-vehicle audio system provided by an embodiment of the present application. The networking mode of the in-vehicle audio system is a wireless networking mode. Exemplarily, the wireless networking mode can be networking through wireless communication technologies such as Wi-Fi, Bluetooth, or Star Flash.

[0111] FIG8 shows another schematic diagram of the in-vehicle audio system provided by an embodiment of the present application. The networking mode of the in-vehicle audio system is a tree-like networking mode. For example, the central system can connect the central subsystem 1 and the central subsystem 2. The central subsystem 1 can be the central system of the main driving area, and the central subsystem 2 can be the central system of the co-driver area. The central subsystem 1 can connect the in-vehicle speaker 1 and the in-vehicle speaker 2. The central subsystem 2 can connect the in-vehicle speaker 3 and the in-vehicle speaker 4.

[0112] Figure 9 shows another schematic diagram of the in-vehicle audio system provided by an embodiment of the present application. The networking mode of the in-vehicle audio system is a mesh networking mode.

[0113] The car speaker and the vehicle body interface may be detachable. For example, the car speaker 1 can be detached from the vehicle body interface 1 and used in outdoor scenes (for example, camping, picnic, hiking scenes) or home scenes (for example, as the smart speaker in Figure 2). For another example, after the car speaker 1 is detached, the car speaker 1 can be powered by a power bank, a battery module or a power supply base, so that the communication module in the car speaker 1 and the mobile phone establish a wireless connection (for example, a Bluetooth connection); or, when the car speaker 1 is an active speaker, it can be powered. In this way, the car audio device is not fixed inside the cabin. By disassembling the car audio device in outdoor scenes, the user's flexibility in using the car audio device can be improved, and the user does not need to carry additional audio devices in outdoor scenes, which helps to improve the user experience.

[0114] For example, a smart speaker in a home can be installed in a vehicle. As shown in Figure 2, smart speaker 1 can be connected to vehicle body interface 3, and smart speaker 2 can be connected to vehicle body interface 6. This allows for flexible addition or subtraction of the number of in-vehicle audio devices within the vehicle, allowing users to adjust the location and / or number of in-vehicle audio devices within the cabin, creating diverse audio environments for users and enhancing the flexibility of in-vehicle audio system design.

[0115] In one embodiment, the terminal unit (e.g., an in-vehicle audio device) may employ a modular design. For example, the in-vehicle audio device may include a communication module and other functional modules. Other functional modules include, but are not limited to, one or more of an active noise reduction controller, an in-vehicle lighting controller, a power amplifier module, and a DSP module.

[0116] The power amplifier module can be used as a supplement to the transmission power of the communication line, increase the sound power of the car speakers, and enhance the effect of the car audio system.

[0117] The DSP module can process audio data to improve the performance of the car's audio system.

[0118] The active noise reduction controller can provide active noise reduction capabilities, and can filter out the sound emitted by the vehicle speakers picked up by the microphone through the audio data obtained by the communication module, and only process the noise.

[0119] The vehicle lighting controller can provide the control capability of the vehicle lighting according to the rhythm of audio data, obtain audio data from the communication module, and thus control the vehicle lighting.

[0120] Exemplarily, the vehicle-mounted lighting controller may be an ambient light controller, which may control the ambient light in the vehicle.

[0121] Optionally, the N in-vehicle audio devices include a first in-vehicle audio device, and the first in-vehicle audio device includes an active noise reduction controller, and the active noise reduction controller is configured to receive first audio data from a microphone and perform noise reduction processing on the first audio data.

[0122] For example, if the first in-vehicle audio device is a car speaker 1, the car speaker 1 may include an active noise reduction controller. The active noise reduction controller of the car speaker 1 may receive audio data from a microphone and perform noise reduction on the audio data. The car speaker 1 may then play the noise-reduced audio data.

[0123] In one embodiment, the N in-vehicle audio devices include a second in-vehicle audio device, which includes the microphone, and the second in-vehicle audio device is configured to send the first audio data to the communication module corresponding to the first in-vehicle audio device through the communication module corresponding to the second in-vehicle audio device.

[0124] For example, if the second in-vehicle audio device is in-vehicle speaker 2, the audio data collected by the microphone in in-vehicle speaker 2 can be transmitted to the communication module in in-vehicle speaker 1 via the communication module in in-vehicle speaker 2. The communication module in in-vehicle speaker 1 can then transmit this audio data to the active noise reduction controller of in-vehicle speaker 1, thereby performing active noise reduction on this audio data. The audio data processed by the active noise reduction controller can then be played back by in-vehicle speaker 1. In this way, a closed-loop active noise reduction system can be formed in the main driving area.

[0125] In one embodiment, the first in-vehicle audio device includes the microphone.

[0126] For example, the vehicle-mounted speaker 1 may include a microphone and an active noise reduction controller. Thus, when the microphone collects audio data, it may be sent to the active noise reduction controller. Active noise reduction may be achieved through a single vehicle-mounted speaker.

[0127] In one embodiment, the N in-vehicle audio devices include a third in-vehicle audio device, and the third in-vehicle audio device includes a in-vehicle lighting controller. The in-vehicle lighting controller is used to receive second audio data from a communication module corresponding to the third in-vehicle audio device; and control the operation of the in-vehicle lighting according to the second audio data.

[0128] In one embodiment, the third vehicle speaker may be vehicle speaker 5. The communication module of vehicle speaker 5 may receive audio data and transmit the audio data to the vehicle lighting controller. The vehicle lighting controller may control the vehicle lighting in the driver's seat, passenger seat, second row left area, and second row right area based on the audio data.

[0129] Optionally, the sound system is located in a vehicle, and the vehicle lamp controller is used to control the vehicle lamps in a first area of ​​the vehicle according to the second audio data, where the first area is the area corresponding to the third vehicle audio device.

[0130] In one embodiment, the first area may be an area where the third in-vehicle audio device is located.

[0131] For example, the third vehicle speaker may be the vehicle speaker 5. The communication module of the vehicle speaker 5 may receive audio data and send the audio data to the vehicle lamp controller. The vehicle lamp controller may control the operation of the vehicle lamps in the left area of ​​the second row according to the audio data.

[0132] In one embodiment, the first area may include other areas except the area where the third in-vehicle audio device is located.

[0133] For example, the third vehicle speaker may be vehicle speaker 5. The communication module of vehicle speaker 5 may receive audio data and transmit the audio data to the vehicle lighting controller. The vehicle lighting controller may control the operation of the vehicle lighting in the second row right area, or control the operation of the vehicle lighting in the second row left area and the second row right area based on the audio data.

[0134] In one embodiment, the N in-vehicle audio devices include a fourth in-vehicle audio device, and the fourth in-vehicle audio device is further configured to send the audio sink capability and / or location information of the fourth in-vehicle audio device to the processor via a communication module corresponding to the fourth in-vehicle audio device.

[0135] For example, the in-vehicle audio devices 1-8 may transmit the audio sink capabilities and / or location information of each in-vehicle audio device to the vehicle's computing platform. After receiving the audio sink capabilities and / or location information of each in-vehicle audio device, the computing platform may determine tuning parameters, thereby controlling the operation of the in-vehicle audio devices 1-8 based on the tuning parameters.

[0136] The above example uses the example of each vehicle audio device sending its corresponding audio sink capabilities and / or location information to the computing platform, but the embodiments of the present application are not limited to this. For example, vehicle audio device 1 and vehicle audio device 2 may send their corresponding audio sink capabilities and / or location information to the computing platform. The computing platform can then determine the tuning parameters for the driver's seat area based on this information, thereby improving the listening experience of the user in the driver's seat area.

[0137] In one embodiment, the N in-vehicle audio devices include a fifth in-vehicle audio device, and the fifth in-vehicle audio device includes a power amplifier module.

[0138] In one embodiment, the N in-vehicle audio devices include a sixth in-vehicle audio device, and the sixth in-vehicle audio device includes a digital signal processing (DSP) module.

[0139] Figure 10 shows a schematic diagram of an in-vehicle audio device and a vehicle body interface provided by an embodiment of the present application. If the communication module of the in-vehicle audio device is a communication interface, the communication interface of the in-vehicle audio device and the communication interface of the vehicle body interface can be located on the same side, which facilitates docking between the communication interfaces.

[0140] In one embodiment, if the in-vehicle audio system adopts the star networking mode as shown in FIG5 , a line-in interface may be reserved for the vehicle body interface.

[0141] In one embodiment, if the in-vehicle audio system uses the daisy-chain networking configuration shown in Figure 6 and a vehicle body interface is not connected to an in-vehicle audio device, a line module can be reserved for that vehicle body interface. Figure 11 shows a schematic diagram of the line module provided in an embodiment of the present application. The line module connects the line-in interface and the line-out interface.

[0142] The terminal unit (eg, a car audio device) provided in an embodiment of the present application is described above in conjunction with FIG. 1 to FIG. 11 . The following describes the process of determining the tuning parameters in an embodiment of the present application in conjunction with the embodiment.

[0143] Figure 12 shows a schematic block diagram of a vehicle provided by an embodiment of the present application. The vehicle may include N in-vehicle audio devices and a computing platform 120. The N in-vehicle audio devices may be connected to the computing platform 120 in a wireless or wired manner.

[0144] Exemplarily, the N in-vehicle audio devices may be the in-vehicle speakers 1 - 8 described above.

[0145] For example, the computing platform 120 may include a central system having communication and data processing functions. The central system may receive audio sink capability and location information transmitted by each of the N in-vehicle audio devices, thereby enabling the central system to determine tuning parameters based on the audio sink capability and location information of each in-vehicle audio device.

[0146] The computing platform 120 may include one or more processors, such as processors 121 to 12n (n is a positive integer). A processor is a circuit with signal processing capabilities. In one implementation, the processor may be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of a hardware circuit. The logical relationship of the hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, the processor may also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. In addition, the computing platform 120 may also include a memory for storing instructions. Some or all of the processors 121 to 12n may call the instructions in the memory and execute the instructions to implement corresponding functions.

[0147] Figure 13 shows a schematic flow chart of a control method 1300 provided in an embodiment of the present application. The method 1300 can be executed by the vehicle 1200, or the method 1300 can be executed by the above-mentioned computing platform 120 (for example, a central system), or the method 1300 can be executed by a system-on-a-chip (SoC) in the above-mentioned computing platform, or the method 1300 can be executed by a processor or chip in the computing platform. The following description will be made using the example that the execution subject is the central system. The method 1300 includes S1310, S1320 and S1330.

[0148] S1310: The central system obtains the audio sink capability and location information of one or more in-vehicle audio devices.

[0149] In one embodiment, the central system obtains the audio sink capability and location information of one or more terminal units, including: after detecting the user input, the central system obtains the audio sink capability and location information of one or more vehicle audio devices.

[0150] For example, when detecting that the user issues a voice command "start tuning", the central system can obtain the audio host capabilities and location information of the vehicle speakers 1-8.

[0151] In one embodiment, the central system obtains the audio host capability and location information of one or more terminal units, including: when detecting that the number and / or quantity of the one or more vehicle audio devices has changed, the central system receives the changed audio host capability and location information of the one or more vehicle audio devices.

[0152] For example, using the in-vehicle audio system shown in Figure 4 as an example, after a vehicle leaves the factory, the user can initiate tuning by sending a command to the vehicle. For example, upon detecting the user's voice command "Start tuning," the central system can send a control signal to the in-vehicle speakers 1-8. This control signal can be used to instruct the in-vehicle speakers 1-8 to upload their audio sink capabilities and location information to the central system.

[0153] For example, after the central system determines the tuning parameters for vehicle speakers 1-8, vehicle speakers 1-8 may periodically transmit their corresponding audio sink capabilities and location information to the central system. If the central system determines that it has not received the audio sink capabilities and location information for vehicle speakers 7 and 8 within a predetermined period of time, the central system may re-tune the audio based on the audio sink capabilities and location information for vehicle speakers 1-6.

[0154] For example, after the central system determines the tuning parameters for vehicle speakers 1-8, it can monitor the vehicle body interfaces corresponding to the vehicle speakers. If the central system determines that vehicle body interfaces 10 and 11 have not supplied power to the vehicle speakers for a predetermined period of time, the central system can re-tune the vehicle speakers based on their audio sink capabilities and location information.

[0155] For example, after the central system determines the tuning parameters for the vehicle speakers 1-8, it can monitor the vehicle body interface corresponding to the vehicle speakers. When the central system determines that a terminal unit (e.g., smart speaker 1) is connected to vehicle body interface 3, it can send a control command to smart speaker 1, instructing it to send its audio sink capabilities and location information to the central system. This allows the central system to determine the tuning parameters based on the audio sink capabilities and location information of the vehicle speakers 1-8 and smart speaker 1.

[0156] The above S1310 is described using the example of an in-vehicle audio device sending its audio sink capabilities and location information to the central system. The embodiments of the present application are not limited to this. After the in-vehicle audio device is connected to the vehicle body interface, its audio sink capabilities can also be sent to the central system via the communication interface in the vehicle body interface. The central system can determine the tuning parameters based on the audio sink capabilities of the in-vehicle audio device and the location of the vehicle body interface (which can serve as the location of the in-vehicle audio device).

[0157] S1320: The central system determines a first tuning parameter according to the audio sink capability and location information of the one or more in-vehicle audio devices.

[0158] In one embodiment, the central system determines the first tuning parameter based on the audio host capabilities and location information of the one or more in-vehicle audio devices, including: the central system determines the first tuning parameter based on the user's location information, the user's ear height, and the audio host capabilities and location information of the one or more in-vehicle audio devices.

[0159] In one embodiment, before the central system determines the first tuning parameter based on the user's location information, the user's ear height, and the audio host capabilities and location information of the one or more in-vehicle audio devices, the method 1300 also includes: the central system obtains the user's location information and the user's ear height.

[0160] The above central system obtaining the user's location information and the user's ear height can also be understood as the central system obtaining the user's three-dimensional coordinates.

[0161] Exemplarily, the central system may obtain the user's location information in the following ways, but is not limited to:

[0162] (1) The central system can determine the user's position in the cabin by combining data collected by the pressure sensor on the seat. For example, when the central system determines that the pressure value collected by the pressure sensor in the seat in the second row right area is greater than a preset pressure value, it determines that the user is in the second row right area, and thus can determine the center point (or other preset point) of the second row right area as the user's position.

[0163] (2) The central system can obtain a user's instruction, which is used to indicate the user's location. For example, when the central system obtains touch data on the central control screen indicating that the user has moved the desired tuning position (e.g., the emperor's seat) to the right area of ​​the second row, the central system can determine that the center point of the right area of ​​the second row (or other preset point) is the user's location.

[0164] (3) The central system can determine the user's location by combining data collected by sensors in the cabin (e.g., cameras, lidar, etc.).

[0165] The above central system may obtain the user's location information through any one of the methods, or may combine multiple methods to obtain the user's location information.

[0166] Exemplarily, the central system acquires the user's ear height in the following ways, including but not limited to:

[0167] (1) The central system stores the height information of user 1. The central system can obtain the image captured by the camera in the cabin and determine that user 1 is in the right area of ​​the second row based on the image. It can also estimate the ear height of user 1 based on the height information of user 1 and the seat design parameters.

[0168] (2) The central system can obtain the image captured by the camera in the cabin and estimate the ear height of user 1 based on the image and the cabin height parameters.

[0169] (3) The central system can obtain the user's posture parameters sent by the seat in the right area of ​​the second row, and thus estimate the ear height of user 1 based on the posture parameters.

[0170] The above central system may obtain the user's ear height through any one of the methods, or may combine multiple methods to obtain the user's ear height.

[0171] In one embodiment, the location information indicates that the user is located at a first location, and before the central system controls the one or more vehicle audio devices to operate according to the first tuning parameters, the method 1300 also includes: the central system controls the one or more vehicle audio devices to emit audio data according to the first tuning parameters; the central system determines that the difference in fit between the frequency response curve of the sound at the first location and the preset curve is within a preset range.

[0172] The above curve may be a human hearing curve, which may reflect a user's preference for a certain type of music.

[0173] The above description uses the example of automatically stopping the tuning process when the first tuning parameter reaches a preset condition, but the embodiments of the present application are not limited to this. For example, the tuning process can also be stopped when the audio effect experienced by the user in the right area of ​​the second row meets their expectations. When the vehicle detects a user instruction (for example, the user issues a voice command "stop tuning"), the tuning process can be stopped and the tuning parameters can be output.

[0174] In one embodiment, the central system determines the first tuning parameter based on the audio host capabilities and location information of the one or more in-vehicle audio devices, including: the central system obtains the second tuning parameter; the central system inputs the second tuning parameter and the audio host capabilities and location information of the one or more in-vehicle audio devices into a prediction model to obtain the first tuning parameter, and the prediction model includes a three-dimensional cabin model and / or a sound wave propagation model.

[0175] The second tuning parameter may be a random tuning parameter, or may be a tuning parameter obtained during the last tuning process of the central system.

[0176] After obtaining the second tuning parameters, the central system can input the second tuning parameters, along with the audio sink capabilities and location information of one or more in-vehicle audio devices, into a prediction model to obtain the first tuning parameters. The prediction model can include a three-dimensional cabin model and / or a sound wave propagation model. This prediction model can simulate sound wave propagation within the cabin, thereby verifying the impact of the tuning parameters on the sound quality.

[0177] In one embodiment, the central system determines the first tuning parameter based on the music host capability and location information of the one or more vehicle audio devices, including: the central system determines the first tuning parameter based on the music host capability and location information of the one or more vehicle audio devices and a mapping relationship; wherein the mapping relationship is a mapping relationship between the music host capability of the vehicle audio device, the location of the vehicle audio device and the tuning parameter.

[0178] For example, Table 1 shows the mapping relationship of the hardware system of the vehicle audio system.

[0179] Table 1

[0180] For example, if the audio sink capabilities and locations sent by the in-car audio device match (AA, BB / (x1, y1, z1), (x2, y2, z2)) in Table 1, the central system can determine that it has identified a hardware system with configuration 1. Thus, the tuning parameters are output through the mapping relationship shown in Table 1.

[0181] Exemplarily, the first configuration may be a low configuration.

[0182] For example, Table 2 shows the mapping relationship of the hardware system of the vehicle audio system under configuration 2.

[0183] Table 2

[0184] Exemplarily, the second configuration may be a mid-range configuration or a high-range configuration.

[0185] Tables 1 and 2 above are merely illustrative and are not specifically limited in the embodiments of the present application. For example, the mapping relationship may also include the capabilities of a DSP module, which includes but is not limited to processing dual channels into multiple channels and high, medium, and low-frequency tuning. The above DSP module may be a centralized DSP module or a distributed DSP module.

[0186] When the DSP module is a centralized DSP module, it may be located in the central system.

[0187] If the DSP module is a distributed DSP module, it can be located in one or more in-vehicle audio devices. In this way, the in-vehicle audio devices can carry the capabilities of the DSP module in the audio sink. The central system can determine the tuning parameters based on the capabilities of the DSP modules in different in-vehicle audio devices.

[0188] In one embodiment, the central system determines the first tuning parameter based on the music host capabilities and location information of the one or more in-vehicle audio devices and a mapping relationship, including: the central system determines multiple tuning parameters based on the music host capabilities and location information of the one or more in-vehicle audio devices and a mapping relationship; the central system determines the first tuning parameter from the multiple tuning parameters based on the user's physiological characteristics information.

[0189] For example, through the above mapping relationship, multiple tuning parameters under different tuning styles can be determined. The central system can further determine the first tuning parameter from the multiple tuning parameters in combination with the user's physiological characteristics information.

[0190] S1330: The central system controls the one or more in-vehicle audio devices to operate according to the first tuning parameter.

[0191] After determining the tuning parameters, the central system may control the operation of the one or more in-vehicle audio devices according to the first tuning parameters.

[0192] In one embodiment, the one or more in-vehicle audio devices include a first in-vehicle audio device and a second in-vehicle audio device, and the method 1300 further includes: the central system establishing a communication connection between the first in-vehicle audio device including an active noise reduction controller and the second in-vehicle audio device including a microphone.

[0193] In addition to sending its audio host capability and location information to the central system, the in-vehicle audio device can also send other capability information of the in-vehicle audio device to the central system. For example, as shown in Figure 4, the in-vehicle speaker 1 includes an active noise reduction controller, and the in-vehicle speaker 2 includes a microphone. The in-vehicle speaker 1 can send information to the central system that it has an active noise reduction function, and the in-vehicle speaker 2 can send information to the central system that it includes a microphone. In this way, the central system can establish a connection between the central system and the in-vehicle speaker 1 and a connection between the central system and the in-vehicle speaker 2, and at the same time, the central system can also establish a connection between the in-vehicle speaker 1 and the in-vehicle speaker 2. In this way, a closed-loop system of active noise reduction can be implemented in the main driving area.

[0194] The above-mentioned car speakers 1 and car speakers 2 can be automatically established by the central system, or the central system can also establish them based on user input. For example, after obtaining the functional information included in the car speakers 1-8, the central system can display the functions of each car speaker through the central control screen and prompt the user to establish a closed-loop system for active noise reduction. After detecting the user's input selecting car speakers 1, car speakers 2, car speakers 3 and car speakers 4, the central system can establish connections between car speakers 1, car speakers 2, car speakers 3 and car speakers 4, thereby realizing a closed-loop system for active noise reduction in the front area.

[0195] In one embodiment, the one or more in-vehicle audio devices include a third in-vehicle audio device, and the method 1300 further includes: the hub system establishing a communication connection between the third in-vehicle audio device including the in-vehicle lamp controller and the in-vehicle lamp.

[0196] For example, as shown in Figure 4, the vehicle speaker 5 includes an active noise reduction controller. Based on the location information transmitted by the vehicle speaker 5, the central system can determine that it is located in the second row, left area. The central system can then establish a communication connection between the vehicle speaker 5 and the vehicle lights in the second row, left area. In this way, after receiving audio data, the communication module of the vehicle speaker 5 can send this audio data to the vehicle light controller, which then controls the vehicle lights in the second row, left area, based on the audio data.

[0197] The communication connection between the above-mentioned vehicle speakers 5 and the vehicle lamps in the left area of ​​the second row can be automatically established by the central system, or it can be established by the central system after receiving the user's input. For example, after the central system obtains the functional information included in the vehicle speakers 1-8, it can display the functions of each vehicle speaker through the central control screen and prompt the user to select the vehicle lamps that can be controlled by the vehicle speakers 5. After detecting the user's selection of the vehicle lamps in the left area of ​​the second row and the vehicle lamps in the right area of ​​the second row, the central system can establish a connection between the vehicle speakers 5, the vehicle lamps in the left area of ​​the second row, and the vehicle lamps in the right area of ​​the second row.

[0198] FIG14 shows a schematic flow chart of a control method 1400 provided in an embodiment of the present application. The method 1400 can be implemented by an in-vehicle audio device and a central control system, wherein the in-vehicle audio device includes a speaker and a first communication module, and the central control system includes a tuning system and a second communication module. The method 1400 includes:

[0199] S1401: The first communication module sends the audio sink capability and location information of the in-vehicle audio device to the second communication module.

[0200] Exemplarily, the audio host capability includes information on the maximum volume of the in-vehicle audio device, frequency information of the emitted sound (e.g., high frequency, medium frequency, or low frequency), information indicating the bandwidth supported by the speakers, controller, and communication module in the in-vehicle audio device, etc.

[0201] S1402: The second communication module sends the audio sink capability and location information of the vehicle audio device to the tuning system.

[0202] S1403: The tuning system starts the tuning process.

[0203] For example, upon detecting user input (e.g., a user issuing a voice command "start tuning"), the tuning system may issue a broadcast message instructing the in-cabin speakers to transmit the audio sink capability and location information. Within a preset time period, the tuning system may receive the audio sink capability and location information of each in-cabin speaker from the in-cabin speakers 1-8, thereby initiating the tuning process.

[0204] Exemplarily, the tuning system may also monitor each vehicle body interface and restart the tuning process when it is determined that the vehicle audio device connected to a certain vehicle body interface has been removed, or when it is determined that a vehicle body interface has been connected to a vehicle audio device instead of being connected to the vehicle audio device.

[0205] S1404: Obtain tuning parameter 1.

[0206] Exemplarily, the tuning parameter 1 may be a random tuning parameter, or may be a tuning parameter output by the central system during the last tuning process.

[0207] S1405: The tuning system generates an audio stream according to the tuning parameters and sends the audio stream to the second communication module.

[0208] S1406: The second communication module sends the audio stream to the first communication module.

[0209] S1407: The first communication module sends the audio stream to the speaker so that the speaker plays the audio stream.

[0210] S1408: The tuning system determines whether the audio stream played by the speaker meets the condition for terminating tuning.

[0211] Exemplarily, the condition for terminating tuning may be that the average deviation of the fit between the frequency response curve of the sound at a specified position (generally a specified emperor's seat) and the human ear auditory curve (or the preference for the auditory curve for a certain type of music) is within x% (x can be a system default or set by the user).

[0212] When the tuning system determines that the tuning termination condition is not met, S1409 is executed; otherwise, S1411 is executed.

[0213] S1409: When the tuning system determines that the tuning termination condition is not met, the tuning parameter 1 and the audio sink capability and location information of the vehicle audio device are input into the prediction model to obtain the tuning parameter 2.

[0214] S1410, repeatedly executing S1404-S1408 until the audio stream played by the speaker meets the condition for terminating tuning.

[0215] S1411: Output the final tuning parameters and stop tuning.

[0216] Optionally, the tuning system may also determine the tuning parameters in conjunction with the user's three-dimensional coordinate information during the tuning process. For example, the tuning system may input the user's three-dimensional coordinates, tuning parameter 1, and the audio sink capabilities and location information of the in-vehicle audio device into a prediction model to obtain tuning parameter 2.

[0217] FIG14 illustrates an example of determining tuning parameters using a prediction model. Tuning parameters can also be determined using a mapping relationship. FIG15 shows a schematic flow chart of a control method 1500 provided in an embodiment of the present application. The method 1500 can be implemented by an in-vehicle audio device and a central control system, wherein the in-vehicle audio device includes a speaker and a first communication module, and the central control system includes a tuning system, a centralized DSP module, and a second communication module. The method 1500 includes:

[0218] S1501: The first communication module sends the audio sink capability and location information of the in-vehicle audio device to the second communication module.

[0219] S1502: The second communication module sends the audio sink capability and location information of the vehicle audio device to the tuning system.

[0220] S1503: The DSP module sends DSP capability information to the tuning system.

[0221] There is no actual order between the above S1502 and S1503.

[0222] S1504: The tuning system determines tuning parameters according to the audio sink capability, location information, DSP capability information, and mapping relationship of the vehicle audio device.

[0223] The above DSP module is an optional module in the central system. The central system may not include a DSP module, so that the mapping relationship may include the corresponding relationship between the audio host capability, location information and tuning parameters. Alternatively, at least some of the one or more in-vehicle audio devices may include a DSP module, and at least some of the in-vehicle audio devices may send DSP capability information to the tuning system, so that the tuning system determines the tuning parameters based on the audio host capability, location information, DSP capability information and mapping relationship of the in-vehicle audio devices.

[0224] Illustratively, the mapping relationship may be as shown in Table 1 or Table 2 above.

[0225] When transmitting signaling or data between the above central system and each in-vehicle audio device, a time-division connection networking transmission configuration can be implemented. For example, within the (L-1)th time granularity, the central system can send data to in-vehicle audio device 1; within the Lth time granularity, the central system can send data to in-vehicle audio device 2; and within the (L+1)th time granularity, the central system can receive data from in-vehicle audio device 3. Considering the limited resources of the communication frequency band, this communication connection networking method is more flexible and can support stronger and more functions.

[0226] Figure 16 shows a schematic block diagram of a control device 1600 provided in an embodiment of the present application. As shown in Figure 16, device 1600 includes: an acquisition unit 1610 for acquiring the audio sink capabilities and location information of one or more in-vehicle audio devices; a determination unit 1620 for determining a first tuning parameter based on the audio sink capabilities and location information of the one or more in-vehicle audio devices; and a control unit 1630 for controlling the operation of the one or more in-vehicle audio devices based on the first tuning parameter.

[0230] Optionally, the determining unit 1620 is configured to determine the first tuning parameter based on the audio sink capabilities and location information of the one or more in-vehicle audio devices and a mapping relationship; wherein the mapping relationship is a mapping relationship between the audio sink capabilities of the in-vehicle audio device, the location of the in-vehicle audio device, and the tuning parameter.

[0234] Optionally, the one or more in-vehicle audio devices include a third in-vehicle audio device, and the control unit 1630 is configured to control the third in-vehicle audio device including the in-vehicle lamp controller to establish a communication connection with the in-vehicle lamp.

[0235] For example, the acquisition unit 1610 may be the computing platform in FIG12 or a processing circuit, processor, or controller in the computing platform. For example, if the acquisition unit 1610 is the processor 121 in the computing platform, the processor 121 may acquire the audio sink capabilities and / or location information of one or more in-vehicle audio devices.

[0236] For another example, the determining unit 1620 may be the computing platform in FIG12 or a processing circuit, processor, or controller in the computing platform. For example, if the determining unit 1620 is the processor 122 in the computing platform, the processor 122 may determine the tuning parameters of the one or more in-vehicle audio devices based on the audio sink capabilities and / or location information of the one or more in-vehicle audio devices obtained by the processor 121.

[0237] For another example, control unit 16300 may be the computing platform in FIG1 , or a processing circuit, processor, or controller within the computing platform. For example, if control unit 1630 is processor 123 within the computing platform, processor 123 may control the operation of one or more in-vehicle audio devices based on the tuning parameters of the one or more in-vehicle audio devices determined by processor 122.

[0238] The functions implemented by the above-mentioned acquisition unit 1610, the functions implemented by the determination unit 1620, and the functions implemented by the control unit 1630 can be implemented by different processors, or some functions can be implemented by the same processor, or they can also be implemented by the same processor.
