[0062] Figure 4 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this disclosure. Detailed Implementation

[0063] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0064] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0065] Currently, achieving a soundproof cabin effect inside a vehicle can provide a better experience for passengers who need to work or require a quiet environment; however, the soundproof cabin can only be opened when the vehicle is stationary.

[0066] For example, when a vehicle is parked in a parking lot or a designated storage area, it can be put into a soundproof cabin to restore its quiet working space for passengers who need to handle work matters.

[0067] However, the current methods for creating a soundproof cabin in a vehicle mainly rely on physical sound isolation. For example, when passengers need to handle work-related matters, they can close all the doors and windows of the vehicle to isolate the sound interaction between the inside and outside of the vehicle, thereby reducing the impact of external noise on the occupants.

[0068] However, the sound insulation efficiency mentioned above is not high, making it difficult to provide a relatively quiet space. On the one hand, the doors and windows cannot effectively block external sounds, allowing external noise to still penetrate into the vehicle and affect the occupants. On the other hand, noise is also generated inside the vehicle, which will still affect the occupants. Consequently, it is difficult to effectively eliminate noise in the vehicle cabin.

[0069] For example, this disclosure provides a noise reduction processing method, apparatus, electronic device, and medium that obtains the location of at least one sound source in a vehicle compartment by responding to a trigger operation of a target mode. The target mode can be used to instruct noise reduction processing on the sound emitted by at least one sound source. Based on the location of at least one sound source in the vehicle compartment and the location of at least one seat in the vehicle compartment, noise reduction processing is performed on the sound in the vehicle compartment. Thus, noise reduction of the vehicle compartment can be achieved based on the location of the seats in the vehicle compartment, which facilitates providing a quieter space for passengers.

[0070] See details Figure 1 As shown in the example.

[0071] Figure 1 This is a schematic flowchart illustrating a noise reduction processing method provided in an embodiment of this disclosure. The method in this embodiment can be executed by a noise reduction processing device, which can be implemented in hardware / software and configured in an electronic device. It can implement the noise reduction processing method described in any embodiment of this application. Figure 1 As shown, the method specifically includes the following:

[0072] S110, In response to the triggering operation of the target mode, obtain the location of at least one sound source in the carriage.

[0073] The target mode can be used to instruct noise reduction processing on the sound emitted by the sound source.

[0074] Among them, the triggering operation of the target mode can be used to instruct the vehicle compartment to enter the sound noise reduction process in order to restore the realization of the quiet cabin inside the vehicle compartment.

[0075] It should be noted that the triggering operation of the target mode can include the following multiple implementation methods.

[0076] In some embodiments, the target mode can be triggered by activating a virtual control on a display screen inside the vehicle compartment.

[0077] For example, a target mode may correspond to a specific function in the vehicle system, which can be controlled by a display screen in the passenger compartment. Passengers can trigger the target mode by activating the virtual control corresponding to the specified function on the display screen.

[0078] The triggering operations for virtual controls may include, but are not limited to: single click, double click, and swipe.

[0079] In other embodiments, the target mode can be triggered by physical controls inside the vehicle compartment.

[0080] For example, a target mode may correspond to a specific function in the vehicle system, which can be controlled by a physical control inside the vehicle. Passengers can trigger the target mode by activating the physical control.

[0081] The triggering operations for physical controls may include, but are not limited to: single press, multiple presses, rotation, etc.

[0082] Based on the description of the above embodiments, the vehicle compartment may include multiple sound sources, and the at least one sound source mentioned above may be all or part of the sound sources that are currently occurring (or are in an active state) among the multiple sound sources included in the vehicle compartment.

[0083] For example, if a vehicle compartment contains multiple sound sources, namely sound source A, sound source B, and sound source C, where sound source A and sound source C are in an on state, and sound source B is in a off state, then obtaining the position of at least one sound source in the compartment can be done by obtaining the position of sound source A and the position of sound source B.

[0084] The sound sources may include, but are not limited to: speakers in the vehicle compartment, air conditioning system, ventilation system, etc.

[0085] S120. Based on the location of at least one sound source in the carriage and the location of at least one seat in the carriage, noise reduction processing is performed on the sound in the carriage.

[0086] By moving the seats, the relative position of the sound source and each seat in the vehicle can be changed, thereby changing the direction of the sound waves emitted by the sound source. This alters the sound field within the vehicle, reduces the propagation range of the sound field, and reconstructs the acoustic structure of the vehicle. This allows for noise absorption through the seats, creating a more effective soundproof cabin inside the vehicle.

[0087] In this process, at least one seat in the vehicle compartment will be rearranged so that at least one seat at a given sound source will absorb and process the sound emitted by that sound.

[0088] It should be noted that when rearranging the seats in the vehicle cabin, the arrangement can also be based on the usage status of the seats. For example, if the front seats need to be moved to the frontmost position, and no one is sitting in the front seats, they can be moved to the frontmost position of the vehicle cabin. If someone is sitting in the front seats, space can be reserved for the passengers before moving the front seats. This way, the seating experience of passengers will not be affected when moving the seats in the vehicle cabin.

[0089] The noise reduction processing method provided in this embodiment obtains the location of at least one sound source in the carriage in response to the triggering operation of the target mode. The target mode can be used to instruct noise reduction processing to be performed on the sound emitted by at least one sound source. Based on the location of at least one sound source in the carriage and the location of at least one seat in the carriage, noise reduction processing is performed on the sound in the carriage. Thus, noise reduction of the vehicle carriage can be achieved based on the location of the seats in the carriage, which is convenient for providing a quieter space for passengers.

[0090] Based on the description of the above embodiments, during the noise reduction process for sound in the vehicle compartment, or before the noise reduction process for sound in the vehicle compartment, this embodiment may further include:

[0091] Adjust at least one sound source to a low-wind mode, which is used to characterize the sound intensity emitted by the sound source to be at its minimum;

[0092] And / or, adjust the external fasteners inside the carriage to be in a tightened state to reduce the amplitude of vibration.

[0093] Among them, at least one sound source can be adjusted to a low wind mode, or the external fasteners inside the carriage can be adjusted to a tightened state, or at least one sound source can be adjusted to a low wind mode and the external fasteners inside the carriage can be adjusted to a tightened state.

[0094] Among them, by adjusting at least one sound source to a low wind mode, the low wind mode can be used to characterize that the intensity of the sound emitted by the sound source is at its minimum, thereby reducing the noise generated by the sound source.

[0095] For example, the sound source could be the air conditioner. During the noise reduction process in the vehicle cabin, or before the noise reduction process in the vehicle cabin, if the air conditioner is currently in de-ventilation mode, the de-ventilation mode of the air conditioner in the vehicle cabin can be changed to a mode without weak airflow.

[0096] One method involves adjusting the external fasteners inside the carriage to a tightened state to reduce vibration amplitude, thereby avoiding vibration noise inside the vehicle carriage.

[0097] For example, the external fasteners inside the vehicle compartment can be air springs / small tables, which can automatically tighten the inside of the vehicle compartment during or before noise reduction processing of the vehicle compartment.

[0098] Figure 2 This is a schematic flowchart of another noise reduction processing method provided in this embodiment. Based on the above embodiments, this embodiment further includes, before S120, the method of this embodiment may include:

[0099] S111, Obtain the number of sound sources in the carriage and the number of seats in the carriage.

[0100] The number of sound sources in the carriage can be the number of sound sources that are in the open state in the carriage. The number of sound sources in the carriage can be determined by the vehicle's control system based on the connection status of each sound source.

[0101] The number of seats in the carriage can be the total number of seats in the vehicle carriage, and the number of seats in the carriage can be obtained by at least one camera in the vehicle.

[0102] It should be noted that cameras can be pre-installed in different locations within the vehicle compartment to monitor and manage the layout of the vehicle compartment.

[0103] One possible implementation of S120 is as follows:

[0104] S1201. Compare the number of sound sources in the carriage with the number of seats in the carriage.

[0105] By comparing the number of sound sources in the carriage with the number of seats in the carriage, it is possible to match one or more seats to each sound source in the carriage, such as arranging one or more seats at a certain angle at the preset position of the sound source.

[0106] S1202. Based on the comparison between the number of sound sources in the carriage and the number of seats in the carriage, adjust the position of at least one seat in the carriage based on the position of the sound sources in the carriage to perform noise reduction processing on the sound in the carriage.

[0107] When the number of sound sources in the carriage is found to be the same as the number of seats in the carriage, the sound sources and seats in the carriage can be paired one by one, that is, a seat is arranged at the preset position of each sound source in the carriage.

[0108] Alternatively, if the comparison between the number of sound sources in the carriage and the number of seats in the carriage is different, the sound sources in the carriage and the seats in the carriage can be paired in a one-to-many or many-to-one manner. That is, multiple seats can be arranged at the preset position of each sound source in the carriage or each seat in the carriage can be arranged at the interaction position of multiple sound sources.

[0109] Therefore, based on the comparison between the number of sound sources in the carriage and the number of seats in the carriage, the position of each seat in the carriage can be readjusted according to the position of the sound sources in the carriage.

[0110] The noise reduction process for the sound in the carriage, based on the location of at least one sound source in the carriage, the location of at least one seat in the carriage, the number of sound sources in the carriage, and the number of seats in the carriage, can include the following various implementation methods.

[0111] In some embodiments, adjusting the position of at least one seat in the carriage based on the position of the sound sources in the carriage, according to a comparison between the number of sound sources in the carriage and the number of seats in the carriage, may include:

[0112] Ensure that the number of sound sources in the carriage is the same as the number of seats in the carriage;

[0113] Identify the first target seat that matches the first sound source in the carriage;

[0114] Adjust the position of the first target seat in the carriage to the preset position of the first sound source in the carriage.

[0115] When it is determined that the number of sound sources in the carriage is the same as the number of seats in the carriage, it means that each sound source in the carriage can correspond to one seat. After determining the first target seat that matches the first sound source in the carriage, the position of the first target seat in the carriage is adjusted to the preset position of the first sound source in the carriage.

[0116] Before adjusting the position of the first target seat in the carriage to the preset position of the first sound source in the carriage, the method of this embodiment may further include: obtaining the position of the first target seat in the carriage and comparing the position of the first target seat in the carriage with the preset position of the first sound source in the carriage; adjusting the position of the first target seat in the carriage to the preset position of the first sound source in the carriage may include: adjusting the position of the first target seat in the carriage to the preset position of the first sound source in the carriage based on the comparison result of the position of the first target seat in the carriage and the preset position of the first sound source in the carriage.

[0117] The process of adjusting the position of the first target seat in the carriage to the preset position of the first sound source in the carriage, based on the comparison between the position of the first target seat in the carriage and the preset position of the first sound source in the carriage, may include:

[0118] If the comparison between the position of the first target seat in the carriage and the preset position of the first sound source in the carriage is the same, then it is determined that the position of the first target seat in the carriage has been adjusted to the preset position of the first sound source in the carriage; or, if the comparison between the position of the first target seat in the carriage and the preset position of the first sound source in the carriage is different, then the position of the first target seat in the carriage is adjusted to the preset position of the first sound source in the carriage.

[0119] It should be noted that if the distance between the position of the first target seat in the carriage and the preset position of the first sound source in the carriage is less than the preset distance threshold, then the position of the first target seat in the carriage and the preset position of the first sound source in the carriage can be considered to be the same. Therefore, the position of the first target seat in the carriage does not need to be adjusted, reducing ineffective seat adjustments.

[0120] The preset position of the first sound source can be determined based on the installation orientation of the first sound source inside the vehicle compartment.

[0121] For example, if the first sound source is installed at the front of the vehicle compartment, the preset position of the first sound source can be determined as a preset area behind the first sound source; or, if the first sound source is installed at the left side of the vehicle compartment, the preset position of the first sound source can be determined as a preset area to the right of the first sound source; or, if the first sound source is installed at the right side of the vehicle compartment, the preset position of the first sound source can be determined as a preset area to the left of the first sound source; or, if the first sound source is installed at the rear of the vehicle compartment, the preset position of the first sound source can be determined as a preset area in front of the first sound source; or, if the first sound source is installed at the top of the vehicle compartment, the preset position of the first sound source can be determined as a preset area below the first sound source.

[0122] The preset area can correspond to a certain proportion of the sound field coverage of the first sound source, such as 80% of the sound field range.

[0123] Optionally, determining the first target seat that matches the first sound source in the carriage includes:

[0124] Based on the location of at least one sound source in the carriage, the sound source closest to the first target seat is determined as the first sound source.

[0125] Specifically, by comparing the distance between the position of the first target seat and the position of at least one sound source in the carriage, the sound source closest to the first target seat is identified as the first sound source, thereby reducing the moving distance of the first target seat and improving the moving efficiency.

[0126] In other embodiments, adjusting the position of at least one seat in the carriage based on the position of the sound sources in the carriage, according to a comparison between the number of sound sources in the carriage and the number of seats in the carriage, may include:

[0127] The number of sound sources in the carriage is determined to be less than the number of seats in the carriage;

[0128] Identify at least one second target seat that matches the second sound source in the carriage;

[0129] Based on the predetermined orientation information of at least one second target seat, the position of at least one second target seat is adjusted to the preset position of the second sound source in the carriage.

[0130] Specifically, when it is determined that the number of sound sources in the carriage is less than the number of seats in the carriage, it indicates that each sound source in the carriage can correspond to at least one seat. After determining at least one second target seat that matches the second sound source in the carriage, the position of at least one second target seat is adjusted to the preset position of the second sound source in the carriage based on the pre-determined direction information of at least one second target seat.

[0131] Optionally, the process for determining direction information includes:

[0132] Based on the number of second target seats, determine the orientation information of at least one second target seat.

[0133] The orientation of multiple second target seats can be estimated by the number of second target seats, thereby effectively determining the orientation information of at least one second target seat.

[0134] For example, if there are two target seats, namely seat A and seat B, then the orientation information of seat A and seat B can be the same (same arrangement angle), that is, seat A and seat B are arranged side by side; if there are three target seats, namely seat C, seat D and seat E, then the orientation information of seat C, seat D and seat E can be different (different arrangement angles), that is, seat C, seat D and seat E can be arranged based on a certain angle, such as seat C and seat D forming a 15° angle, and seat D and seat E forming a 15° angle.

[0135] It should be noted that the arrangement angle between the seats can be determined based on the size of the vehicle compartment and the sound field distribution of the sound source, and this disclosure does not impose specific limitations on this.

[0136] Referring to the above examples, when there are two second target seats, namely seat A and seat B, the position of at least one second target seat is adjusted to the preset position of the second sound source in the vehicle compartment based on the predetermined orientation information of at least one second target seat. This can be achieved by arranging seat A and seat B side by side at the preset position of the second sound source. Alternatively, when there are three second target seats, namely seat C, seat D and seat E, the position of at least one second target seat is adjusted to the preset position of the second sound source in the vehicle compartment based on the predetermined orientation information of at least one second target seat. This can be achieved by arranging seat C and seat D at a 15° angle and seat D and seat E at a 15° angle at the preset position of the second sound source. The preset position of the second sound source can be determined based on the installation orientation of the second sound source in the vehicle compartment.

[0137] Therefore, after determining that the number of sound sources in the carriage is less than the number of seats in the carriage, at least one second target seat that matches the second sound source in the carriage can be identified, and the position of at least one second target seat can be adjusted to the preset position of the second sound source in the carriage based on the directional information of the at least one second target seat. In this way, the acoustic structure in the carriage can be reasonably improved, so as to make reasonable use of all the seats in the carriage to block noise from at least one sound source.
