[0107] Figure 6 Another schematic diagram of the vehicle audio system provided by an embodiment of the present application is shown. The networking mode of the vehicle audio system is a daisy chain networking mode.

[0108] Figure 7 Another schematic diagram of the in-vehicle audio system provided by the embodiment of the present application is shown. 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.

[0109] Figure 8 Another schematic diagram of the in-vehicle audio system provided by an embodiment of the present application is shown. The networking mode of the in-vehicle audio system is a tree networking mode. Exemplarily, 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-driving 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.

[0110] Fig. 9 Another schematic diagram of the vehicle audio system provided by the embodiment of the present application is shown. The networking mode of the vehicle audio system is a mesh networking mode.

[0111] The vehicle speaker and the vehicle body interface may be detachable. For example, the vehicle speaker 1 may be detached from the vehicle body interface 1 and used in outdoor scenes (e.g., camping, picnic, hiking scenes) or home scenes (e.g., as a Figure 2 For another example, after the vehicle-mounted speaker 1 is disassembled, the vehicle-mounted speaker 1 can be powered by a power bank, a battery module or a power supply base, so that the communication module in the vehicle-mounted speaker 1 and the mobile phone can establish a wireless connection (for example, a Bluetooth connection); or, when the vehicle-mounted speaker 1 is an active speaker, it can be powered. In this way, the vehicle-mounted audio device is not fixed inside the cabin. By disassembling the vehicle-mounted audio device in outdoor scenes, the user's flexibility in using the vehicle-mounted 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.

[0112] For example, the smart speakers in the home can be installed in the car. Figure 2 The smart speaker 1 can be connected to the vehicle body interface 3, and the smart speaker 2 can be connected to the vehicle body interface 6. In this way, the number of vehicle audio devices can be flexibly increased or decreased in the vehicle, and the user can adjust the position and / or number of the vehicle audio devices in the cabin conveniently, thereby creating different sound environments for the user, which helps to improve the flexibility of the vehicle audio system design.

[0113] In one embodiment, the terminal unit (e.g., a vehicle audio device) may be modularly designed. For example, the 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, a vehicle lighting controller, a power amplifier module, and a DSP module.

[0114] 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.

[0115] The DSP module can process audio data to improve the effect of the car's audio system.

[0116] 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.

[0117] The vehicle lamp controller can provide the control capability of the vehicle lamp according to the rhythm of audio data, obtain audio data from the communication module, and thus control the vehicle lamp.

[0118] Exemplarily, the vehicle-mounted lighting controller may be an ambient light controller, which may control the ambient light in the vehicle.

[0119] 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 used to receive first audio data from a microphone; and perform noise reduction processing on the first audio data.

[0120] For example, if the first vehicle audio device is a vehicle speaker 1, the vehicle speaker 1 may include an active noise reduction controller. The active noise reduction controller of the vehicle speaker 1 may receive audio data from a microphone, thereby performing noise reduction on the audio data. The vehicle speaker 1 may play the audio data after noise reduction.

[0121] In one embodiment, 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.

[0122] Exemplarily, taking the case where the second vehicle audio device is a vehicle speaker 2, the audio data collected by the microphone in the vehicle speaker 2 can be sent to the communication module in the vehicle speaker 1 through the communication module in the vehicle speaker 2. The communication module in the vehicle speaker 1 can send the audio data to the active noise reduction controller of the vehicle speaker 1, thereby completing the active noise reduction of the audio data. The audio data processed by the active noise reduction controller can be played by the vehicle speaker 1. In this way, a closed-loop active noise reduction system can be formed in the main driving area.

[0123] In one embodiment, the first in-vehicle audio device includes the microphone.

[0124] Exemplarily, 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.

[0125] In one embodiment, the N vehicle audio devices include a third vehicle audio device, and the third vehicle audio device includes a vehicle lighting controller, and the vehicle lighting controller is used to receive second audio data from a communication module corresponding to the third vehicle audio device; and control the operation of the vehicle lighting according to the second audio data.

[0126] In one embodiment, the third vehicle speaker may be a 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 main driving area, the co-driving area, the second row left area, and the second row right area according to the audio data.

[0127] 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, and the first area is the area corresponding to the third vehicle audio device.

[0128] In one embodiment, the first area may be an area where the third vehicle audio device is located.

[0129] Exemplarily, the third vehicle speaker may be a 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.

[0130] In one embodiment, the first area may include other areas except the area where the third vehicle audio device is located.

[0131] Exemplarily, the third vehicle speaker may be a 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 vehicle lamps in the second row right area to work according to the audio data, or control the vehicle lamps in the second row left area and the second row right area to work.

[0132] In one embodiment, the N vehicle audio devices include a fourth vehicle audio device, and the fourth vehicle audio device is further configured to send the audio host capability and / or location information of the fourth vehicle audio device to the processor via a communication module corresponding to the fourth vehicle audio device.

[0133] Exemplarily, the vehicle audio devices 1-8 may send the audio sink capability and / or location information of each vehicle audio device to the vehicle computing platform. After receiving the audio sink capability and / or location information of each vehicle audio device, the computing platform may determine the tuning parameters, thereby controlling the operation of the vehicle audio devices 1-8 through the tuning parameters.

[0134] In the above, each vehicle audio device in the vehicle sends its corresponding audio host capability and / or location information to the computing platform as an example, and the embodiments of the present application are not limited to this. For example, the vehicle audio device 1 and the vehicle audio device 2 may send their corresponding audio host capability and / or location information to the computing platform, and the computing platform may determine the tuning parameters of the main driving area based on this information, thereby improving the auditory experience of the user in the main driving area.

[0135] 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.

[0136] 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.

[0137] Fig.10 A schematic diagram of a vehicle audio device and a vehicle body interface provided by an embodiment of the present application is shown. If the communication module of the vehicle audio device is a communication interface, the communication interface of the vehicle audio device and the communication interface in the vehicle body interface can be located on the same side, which can facilitate the connection between the communication interfaces.

[0138] In one embodiment, if the vehicle audio system is Figure 5 If the star networking mode is used as shown, a line in interface can be reserved at the vehicle body interface.

[0139] In one embodiment, if the vehicle audio system is Figure 6 When the daisy chain networking mode is shown and a certain body interface has no vehicle audio device connected, a line module can be reserved in the body interface. Fig.11 The schematic diagram of the line module provided in the embodiment of the present application is shown. The line in interface and the line out interface are connected via the line module.

[0140] Combination of the above Figures 1 to 11 A terminal unit (eg, a car audio device) provided in an embodiment of the present application is introduced. The following describes a process for determining tuning parameters in an embodiment of the present application in conjunction with the embodiment.

[0141] Fig.12 A schematic block diagram of a vehicle provided by an embodiment of the present application is shown. The vehicle may include N vehicle audio devices and a computing platform 120. The N vehicle audio devices may be connected to the computing platform 120 in a wireless or wired manner.

[0142] Exemplarily, the N in-vehicle audio devices may be the in-vehicle speakers 1 - 8 described above.

[0143] Exemplarily, the computing platform 120 may include a central system, which may have communication and data processing functions. The central system may receive the audio sink capability and location information sent by each of the N in-vehicle audio devices, so that the central system may determine the tuning parameters according to the audio sink capability and location information of each in-vehicle audio device.

[0144] The computing platform 120 may include one or more processors, such as processors 121 to 12n (n is a positive integer). The 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 may implement certain functions through the logical relationship of a hardware circuit, and the logical relationship of the hardware circuit is fixed or reconfigurable, such as a processor that 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 may 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, the memory is used to store instructions, and some or all of the processors 121 to 12n may call the instructions in the memory and execute the instructions to implement corresponding functions.

[0145] Fig.13A schematic flow chart of a control method 1300 provided in an embodiment of the present application is shown. The method 1300 can be executed by a 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 is an explanation taking the execution subject as an example of a central system. The method 1300 includes S1310, S1320 and S1330.

[0146] S1310, the central system obtains the audio host capability and location information of one or more vehicle audio devices.

[0147] 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's input, the central system obtains the audio sink capability and location information of one or more vehicle-mounted audio devices.

[0148] 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.

[0149] 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.

[0150] For example, Figure 4 Taking the in-vehicle audio system shown as an example, after the vehicle leaves the factory, the user can send a command to the vehicle to start tuning the vehicle. For example, when the vehicle detects the user's voice command "start tuning", the central system can send a control signal to the in-vehicle speakers 1-8, and the control signal can be used to instruct the in-vehicle speakers 1-8 to upload their audio host capabilities and location information to the central system.

[0151] Exemplarily, after the central system determines the tuning parameters of the vehicle audio devices of the vehicle speakers 1-8, the vehicle speakers 1-8 can periodically send their corresponding audio sink capabilities and location information to the central system. When the central system determines that the audio sink capabilities and location information of the vehicle speakers 7 and 8 have not been received within a preset time, the central system can re-tune according to the audio sink capabilities and location information of the vehicle speakers 1-6.

[0152] For example, after the central system determines the tuning parameters of the vehicle audio devices of the vehicle speakers 1-8, the central system can monitor the vehicle body interfaces corresponding to the vehicle speakers. When the central system determines that the vehicle body interfaces 10 and 11 have not supplied power to the vehicle speakers within a preset time, the central system can re-tune the audio according to the audio host capabilities and location information of the vehicle speakers 1-6.

[0153] Exemplarily, after the central system determines the tuning parameters of the vehicle audio devices of the vehicle speakers 1-8, the central system 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 the vehicle body interface 3, the central system can send a control instruction to the smart speaker 1, which instructs the smart speaker 1 to send its audio host capability and location information to the central system. In this way, the central system can determine the tuning parameters based on the audio host capability and location information of the vehicle speakers 1-8 and the smart speaker 1.

[0154] In the above S1310, the example of the vehicle audio device sending the audio host capability and location information to the central system is used for explanation, and the embodiments of the present application are not limited to this. After the vehicle audio device is connected to the vehicle body interface, its audio host capability can also be sent to the central system through the communication interface in the vehicle body interface. The central system can determine the tuning parameters according to the audio host capability of the vehicle audio device and the location of the vehicle body interface (which can be used as the location of the vehicle audio device).

[0155] S1320: The central system determines a first tuning parameter according to the audio host capability and location information of the one or more vehicle audio devices.

[0156] 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 vehicle audio devices, including: the central system determines the first tuning parameter based on the location information of the user, the height of the user's ear, and the audio host capabilities and location information of the one or more vehicle audio devices.

[0157] 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 vehicle audio devices, the method 1300 also includes: the central system obtains the user's location information and the user's ear height.

[0158] 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.

[0159] Exemplarily, the central system acquires the user's location information in the following ways, including but not limited to:

[0160] (1) The central system can determine the user's position in the cabin in combination with the 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, the central system determines that the user is in the second row right area, and thus can determine the center point of the second row right area (or other preset point) as the user's position.

[0161] (2) The central system can obtain a user's instruction, which is used to indicate the user's position. For example, when the central system obtains the touch data of the user moving the desired tuning position (e.g., the emperor's seat) to the right area of ​​the second row on the central control screen, it can determine that the center point of the right area of ​​the second row (or other preset point) is the user's position.

[0162] (3) The central system can determine the user's location based on data collected by sensors in the cockpit (e.g., cameras, lidar, etc.).

[0163] 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.

[0164] Exemplarily, the central system acquires the user's ear height in the following ways, including but not limited to:

[0165] (1) The central system stores the height information of user 1. When the central system obtains the image captured by the camera in the cabin and determines that user 1 is located in the right area of ​​the second row based on the image, it can estimate the ear height of user 1 based on the height information of user 1 and the seat design parameters.

[0166] (2) The central system can obtain the image captured by the camera in the cockpit and estimate the ear height of user 1 based on the image and the height parameters of the cockpit.

[0167] (3) The central system can obtain the posture parameters of the user 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.

[0168] The above central system can obtain the user's ear height through one of the methods, or can also obtain the user's ear height by combining multiple methods.

[0169] In one embodiment, the position information indicates that the user is located at a first position, 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 position and the preset curve is within a preset range.

[0170] The above curve may be a human hearing curve, which may reflect the user's preference for a certain type of music.

[0171] The above is an example of automatically stopping the tuning process when the first tuning parameter reaches a preset condition, and the embodiments of the present application are not limited to this. For example, the tuning process may be stopped when the audio effect felt by the user in the right area of ​​the second row meets his or her expectations. When the vehicle detects a user's command (for example, the user issues a voice command of "stop tuning"), the tuning process may be stopped and the tuning parameters may be output.

[0172] 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 vehicle audio devices, including: the central system obtains the second tuning parameter; the central system inputs the second tuning parameter, the audio host capabilities and location information of the one or more 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.

[0173] 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.

[0174] After obtaining the second tuning parameters, the central system may input the second tuning parameters, the audio host capabilities and location information of one or more vehicle audio devices into the prediction model to obtain the first tuning parameters. The prediction model may include a three-dimensional cabin model and / or a sound wave propagation model. The prediction model may simulate the propagation of sound waves in the cabin, and further verify the influence of the tuning parameters on the sound effects.

[0175] 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.

[0176] Exemplarily, Table 1 shows the mapping relationship of the hardware system of the vehicle audio system to be configured as follows.

[0177] Table 1

[0178]

[0179] For example, if the audio host capability and location sent by the vehicle audio device match (AA, BB / (x1, y1, z1), (x2, y2, z2)) in Table 1, the central system can determine and identify the hardware system of configuration 1. Thus, the tuning parameters are output through the mapping relationship shown in Table 1.

[0180] Exemplarily, the configuration one may be a low configuration.

[0181] Exemplarily, Table 2 shows the mapping relationship of the hardware system of the vehicle audio system under configuration 2.

[0182] Table 2

[0183]

[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 the embodiments of the present application do not specifically limit this. For example, the mapping relationship may also include the capability of a DSP module, which includes but is not limited to processing dual channels into multiple channels, high, medium and low frequency tuning capabilities. The above DSP modules may be centralized DSP modules or distributed DSP modules.

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

[0187] When the DSP module is a distributed DSP module, it can be located in one or more vehicle audio devices, so that the vehicle audio device can carry the capabilities of the DSP module in the audio sink capabilities. The central system can determine the tuning parameters based on the capabilities of the DSP modules in different 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 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 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] Exemplarily, 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 characteristic information.

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

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

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

[0193] In addition to sending its audio sink capability and location information to the central system, the in-vehicle audio device may also send other capability information of the in-vehicle audio device to the central system. Figure 4 As shown, the vehicle speaker 1 includes an active noise reduction controller, and the vehicle speaker 2 includes a microphone. The vehicle speaker 1 can send information that it has an active noise reduction function to the central system, and the vehicle speaker 2 can send information that it includes a microphone to the central system. In this way, the central system can respectively establish a connection between the central system and the vehicle speaker 1 and a connection between the central system and the vehicle speaker 2. At the same time, the central system can also establish a connection between the vehicle speaker 1 and the 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 vehicle speakers 1 and vehicle speakers 2 can be automatically established by the central system, or the central system can also be established according to the user's input. For example, after obtaining the functional information included in the vehicle speakers 1-8, the central system can display the functions of each vehicle 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 vehicle speakers 1, vehicle speakers 2, vehicle speakers 3 and vehicle speakers 4, the central system can establish a connection between vehicle speakers 1, vehicle speakers 2, vehicle speakers 3 and vehicle speakers 4, thereby realizing a closed-loop system for active noise reduction in the front area.

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

[0196] For example, Figure 4As shown, the vehicle speaker 5 includes an active noise reduction controller. The central system can determine that the vehicle speaker 5 is in the left area of ​​the second row according to the position information sent by the vehicle speaker 5, so that the central system can establish a communication connection between the vehicle speaker 5 and the vehicle lamps in the left area of ​​the second row. In this way, after the communication module of the vehicle speaker 5 receives the audio data, the communication module can send the audio data to the vehicle lamp controller, so that the vehicle lamp controller controls the vehicle lamps in the left area of ​​the second row according to 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] Fig.14 A schematic flow chart of a control method 1400 provided in an embodiment of the present application is shown. The method 1400 can be implemented by a vehicle audio device and a central system, wherein the vehicle audio device includes a speaker and a first communication module, and the central 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 vehicle audio device to the second communication module.

[0200] Exemplarily, the audio host capability includes information on the maximum volume of the vehicle audio device, frequency information of the sound emitted (e.g., high frequency, medium frequency or low frequency), information indicating the bandwidth supported by the speakers, controllers, and communication modules in the 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, after detecting the user's input (for example, the user issues a voice command "start tuning"), the tuning system may issue a broadcast message, which instructs the vehicle speakers in the cabin to send the audio sink capability and location information to the tuning system. Within a preset time, the tuning system may receive the audio sink capability and location information of each vehicle speaker sent by the vehicle speakers 1-8, thereby starting the tuning process.

[0204] Exemplarily, the tuning system can also monitor each vehicle body interface. When it is determined that the vehicle audio device connected to a certain vehicle body interface is removed, or when it is determined that a vehicle audio device is connected to a certain vehicle body interface from being never connected to the vehicle audio device, the tuning process can be restarted.

[0205] S1404, obtaining 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 a 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 designated position (generally a designated emperor's seat) and the human ear hearing curve (or the preference for the hearing curve of 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 condition for terminating tuning is not met, S1409 is executed; otherwise, S1411 is executed.

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

[0214] S1410, repeatedly execute 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.

Exemplarily, the tuning system may input the user's three-dimensional coordinates, tuning parameters 1, and the audio host capability and location information of the vehicle audio device into the prediction model to obtain the tuning parameters 2.

[0217] Fig.14 In the example, determining the tuning parameters through a prediction model is used to illustrate that the tuning parameters can also be determined through a mapping relationship. Fig.15 A schematic flow chart of a control method 1500 provided in an embodiment of the present application is shown. The method 1500 can be implemented by a vehicle audio device and a central system, wherein the vehicle audio device includes a speaker and a first communication module, and the central 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 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 of precedence between S1502 and S1503 above.

[0222] S1504: The tuning system determines tuning parameters according to the audio host 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 vehicle audio devices may include a DSP module, and at least some of the 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 vehicle audio device.

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

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