Obviously, the accompanying drawings described below are only some embodiments of the present invention.

[0052] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0053] In practical applications, embodiments of the present invention can collect the first noise signal from the refrigerator and generate a corresponding reverse sound: a first noise reduction signal; then play the first noise reduction signal inside the vehicle.

[0054] By playing a first noise-reducing signal inside the vehicle, this embodiment of the invention can reduce the impact of refrigerator compressor noise on vehicle occupants. In practical applications, the noise of the refrigerator compressor in the vehicle can be collected, and then the vehicle's processor can generate a reverse sound to achieve the purpose of noise reduction.

[0055] This noise reduction mode has the following problems:

[0056] The noise reduction method uses a single source, only collecting the noise from the compressor. The noise from the refrigerator has different effects on users in different positions in the car. If noise reduction is based directly on this single source, it will not be possible to effectively reduce noise for all users in the car.

[0057] Therefore, this invention provides a noise reduction method for refrigerators. This method first collects refrigerator noise in different areas inside the vehicle; then, it performs targeted noise reduction for each area. Compared to existing noise reduction methods, this invention allows all users inside the vehicle to experience effective noise reduction. Specifically, please refer to... Figure 1 , Figure 1 The diagram illustrates a step flowchart of a noise reduction method for a refrigerator according to an embodiment of the present invention. This method can be applied to vehicles; for example, the refrigerator can be a vehicle-mounted refrigerator.

[0058] like Figure 1 As shown, the noise reduction method for refrigerators may include the following steps:

[0059] Step 101: Obtain the first noise signal of the refrigerator collected in different areas of the vehicle.

[0060] In this embodiment of the invention, a first noise signal from the refrigerator can be collected and a corresponding reverse sound, a first noise reduction signal, can be generated. The first noise reduction signal is then played inside the vehicle to reduce the impact of the refrigerator compressor noise on the users inside the vehicle.

[0061] Furthermore, in practical applications, the noise from a refrigerator has varying impacts on users in different positions within the vehicle. If noise reduction is performed directly based on noise collected from a single source, it's impossible to effectively reduce noise for all users in the vehicle. Therefore, embodiments of the present invention can pre-divide the vehicle's cabin space into multiple zones. For example, these zones may include: a driver's area, a front passenger area, a left rear area, a right rear area, etc. Of course, depending on the number of seats, more zones can be divided, and embodiments of the present invention do not limit this.

[0062] After dividing the vehicle's cabin space into zones, when the refrigerator in the vehicle is detected to be running, the first noise signal of the refrigerator can be acquired in different zones of the vehicle. For example, a sound acquisition device can be set up in different zones of the vehicle, and each sound acquisition device can acquire the noise of at least one zone and output the first noise signal for that zone.

[0063] The first noise signal can refer to the audio data collected in one area of ​​the vehicle, specifically regarding the noise emitted by the refrigerator. Due to the characteristics of sound transmission, the first noise signal may differ in different areas.

[0064] Step 102: Based on the first noise signal, determine the first noise reduction signal for each region.

[0065] After obtaining the first noise signal for each region, a corresponding first noise reduction information can be determined for each first noise signal.

[0066] For example, the first noise signal can be analyzed in real time using fast Fourier transform or other spectral analysis techniques to extract its frequency, amplitude, and phase characteristics.

[0067] Then, the spectrum of the first noise signal can be processed to generate a signal with opposite phase; specifically, this can be achieved by inverting the phase spectrum of the first noise signal (i.e., multiplying it by -1). Next, the processed frequency domain signal can be converted back to a time domain signal to generate the first denoised signal.

[0068] In the time domain, a signal with a 90-degree phase difference from the first noise signal can be generated by calculating the Hilbert transform of the noise signal, and then the first noise-reduced signal can be generated by adjusting the phase of this signal.

[0069] Step 103: Play the determined first noise reduction signal for each area.

[0070] After obtaining the first noise reduction signal for each region, the first noise reduction signal determined for each region can be played separately. For example, the first noise reduction signal corresponding to the driver's area can be played for the driver's area, the first noise reduction signal corresponding to the passenger's area can be played for the passenger's area, the first noise reduction signal corresponding to the left rear area can be played for the left rear area, and the first noise reduction signal corresponding to the right rear area can be played for the right rear area. This embodiment of the invention does not limit this.

[0071] In this embodiment of the invention, first noise signals from the refrigerator collected in different areas of the vehicle are acquired; based on the first noise signals, a first noise reduction signal is determined for each area; and the determined first noise reduction signal is played for each area. Through this embodiment of the invention, the impact of in-vehicle refrigerator noise on users inside the vehicle can be reduced by playing noise reduction signals. Furthermore, the impact of in-vehicle refrigerator noise on users in different areas of the vehicle varies. This embodiment of the invention, by first collecting refrigerator noise in different areas of the vehicle and then performing targeted noise reduction for different areas, can effectively reduce the varying degrees of impact of the in-vehicle refrigerator on users in different areas.

[0072] Reference Figure 2 The diagram illustrates a flowchart of another noise reduction method for a refrigerator according to an embodiment of the present invention, which may include the following steps:

[0073] Step 201: Detect whether there are passengers in each area of ​​the vehicle.

[0074] In some feasible embodiments, it is possible to first detect whether there are passengers in the pre-divided areas of the vehicle. For example, a seat occupancy system can be used to detect whether there are passengers in each area of ​​the vehicle; wherein, an area can be associated with a seat, that is, one area corresponds to at least one seat; when the seat occupancy system indicates that a seat is occupied, it can indicate that there are passengers in the area corresponding to that seat.

[0075] Another example is the acquisition of image data of the vehicle's cabin space; the acquired image data is then used to identify whether passengers are present in each area.

[0076] Step 202: Obtain the first noise signal of the refrigerator collected in the area where passengers are present.

[0077] For areas without passengers, since noise reduction is not required, the noise from the refrigerators in that area can be omitted to reduce unnecessary waste of data processing resources and energy. For areas with passengers, since noise reduction is required, it is necessary to use sound acquisition equipment to collect the noise from the refrigerators in that area and obtain the first noise signal collected for that area.

[0078] Step 203: Determine the first noise reduction signal for each region based on the first noise signal.

[0079] After obtaining the first noise signal for each region, a corresponding first noise reduction information can be determined for each first noise signal.

[0080] For example, a corresponding first noise reduction information can be generated directly for each first noise signal; alternatively, a first noise reduction signal can be obtained from a preset database based on the frequency, amplitude, and phase characteristics of the first noise signal. This embodiment of the invention does not limit this approach.

[0081] Step 204: Obtain the second noise signal of the external environment.

[0082] In some feasible implementations, vehicles encounter varying road conditions while driving; ambient noise is then transmitted to passengers inside the vehicle. If the ambient noise exceeds the noise generated by the refrigerator, attempting to reduce the refrigerator's noise may only waste energy without providing a quiet riding environment for passengers. Therefore, a second noise signal from the external environment can be acquired before attempting to reduce the refrigerator's noise. This second noise signal can be a sound signal collected from inside the vehicle in response to external ambient noise.

[0083] Step 205: Determine whether to perform noise reduction operation based on the first noise signal and the second noise signal.

[0084] After obtaining the second noise signal, it is possible to determine whether noise reduction operations need to be performed on the refrigerator based on the volume of the first and second noise signals.

[0085] In one embodiment of the present invention, step 205 can be implemented by the following sub-steps:

[0086] Sub-step 11: Determine whether the volume corresponding to the first noise signal is less than the volume corresponding to the second noise signal.

[0087] In some feasible embodiments, it can be determined whether the volume of the noise corresponding to the first noise signal is less than the volume of the noise corresponding to the second noise signal.

[0088] Sub-step 12: When the volume corresponding to the first noise signal is less than the volume corresponding to the second noise signal, it is determined that the noise reduction operation will not be performed.

[0089] If the volume of the noise corresponding to the first noise signal is less than the volume of the noise corresponding to the second noise signal, then it can be considered that the noise from the outside environment has a greater impact on the passengers inside the vehicle than the noise from the refrigerator. Therefore, there is no need to reduce the noise from the refrigerator. In this case, noise reduction operations for the refrigerator can be skipped to reduce unnecessary energy waste.

[0090] Sub-step 13: When the volume corresponding to the first noise signal is not less than the volume corresponding to the second noise signal, determine to perform noise reduction operation.

[0091] Conversely, if the volume of the noise corresponding to the first noise signal is not less than the volume of the noise corresponding to the second noise signal, then it can be considered that the noise from the refrigerator has a greater impact on the passengers inside the vehicle than the noise from the outside environment. In this case, in order to reduce the impact of the refrigerator noise on the passengers, noise reduction operations can be performed on the refrigerator noise.

[0092] Step 206: When it is determined to perform noise reduction operation based on the first noise signal and the second noise signal, the determined first noise reduction signal is played for each area.

[0093] Specifically, when it is determined that noise reduction operation for refrigerator noise needs to be performed based on the first noise signal and the second noise signal, the determined first noise reduction signal can be played for each area.

[0094] In one embodiment of the present invention, when playing the determined first noise reduction signal for each region, the above method may further include the following steps:

[0095] In response to the first user's operation, the first noise reduction signal is adjusted.

[0096] In some feasible embodiments, different passengers have different auditory perception abilities; in order to meet the needs of different passengers, when playing a determined first noise reduction signal for each area, passengers can perform a first user operation based on their self-perception to adjust the first noise reduction signal, thereby adjusting the frequency, amplitude, phase and other characteristics of the first noise reduction signal.

[0097] In one embodiment of the present invention, the above method may further include the following steps:

[0098] Determine the first operating status information of the refrigerator when the first noise signal is collected; store the correspondence between the first operating status information and the first noise reduction signal in a preset relationship database.

[0099] In some feasible embodiments, since the area is fixed and the noise emitted by the refrigerator is related to the refrigerator's operating state, the first operating state information of the refrigerator can be determined when the first noise signal is collected.

[0100] Then, the correspondence between the first working state information and the first noise reduction signal can be stored in a preset relationship library; in subsequent use, the first noise reduction signal can be directly determined based on the first working state information without having to obtain the first noise signal again. This embodiment of the invention does not limit this.

[0101] In one embodiment of the present invention, the step of storing the correspondence between the first working state information and the first noise reduction signal into a preset relationship database can be implemented in the following way:

[0102] Obtain user ratings submitted for the first noise reduction signal; when the user rating is lower than a preset value, adjust the first noise reduction signal according to the user rating, and store the correspondence between the first working status information and the adjusted first noise reduction signal in a preset relationship database; when the user rating is not lower than the preset value, execute the step of storing the correspondence between the first working status information and the first noise reduction signal in the preset relationship database.

[0103] In some feasible embodiments, after the first noise-reduced signal is played, passengers in the vehicle can submit a corresponding user rating for the first noise-reduced signal. The user rating can be used to evaluate the noise reduction capability of the first noise-reduced signal. For example, the higher the user rating, the stronger the noise reduction capability of the first noise-reduced signal, and the lower the user rating, the weaker the noise reduction capability of the first noise-reduced signal.

[0104] Based on user ratings, the first noise reduction signal can be adjusted. Specifically, when the user rating is lower than the preset value, the first noise reduction signal can be adjusted according to the user rating. Then, the correspondence between the adjusted first noise reduction signal and the first working status information is stored in the preset relationship database so that a more accurate noise reduction signal can be obtained when querying the preset relationship database next time.

[0105] If the user rating is not lower than the preset value, the correspondence between the first working status information and the first noise reduction signal can be directly stored in the preset relationship library for subsequent use.

[0106] For example, such as Figure 3 As shown, sound acquisition devices 31 can be set at different locations in the vehicle 30; one sound acquisition device 31 can acquire the sound of a region and output corresponding signals (e.g., first noise signal, second noise signal) to the ADSP (Audio Digital Signal Processor) 32 of the vehicle 30.

[0107] The vehicle 30 may also be equipped with a refrigerator 33. The noise generated by the refrigerator can be collected by the sound acquisition device 31 and generate a first noise signal.

[0108] After obtaining the first noise signal and the second noise signal, the ADSP32 can generate a first noise-reduced signal and output it to the audio playback device. Figure 3 (Not shown in the diagram, the audio playback device may include multiple devices, which may be set in different locations in the vehicle 30 for playback; alternatively, audio playback devices may be set in multiple locations in the vehicle 30.)

[0109] In addition, the SOC (System on Chip) 34 of the vehicle 30 can determine the first working state information of the refrigerator 33 when the first noise signal is collected, and store the correspondence between the first working state information and the first noise reduction signal in a preset relational library, so that when noise reduction is performed later, the first noise reduction signal can be directly obtained from the preset relational library and sent to the ADSP 32 for playback.

[0110] like Figure 4 As shown, after the vehicle is started, you can first check whether the sound acquisition device, audio playback device, ADSP and SOC are working properly.

[0111] When the sound acquisition device, audio playback device, ADSP, and SOC are all detected to be functioning normally, it is possible to detect whether there are passengers in each area of ​​the vehicle; if there are no passengers in any area, then noise reduction for the refrigerator noise is not required.

[0112] If there are passengers in the area, it can be detected whether the refrigerator in the vehicle is running; if the refrigerator is not running, noise reduction for the refrigerator is not required.

[0113] Conversely, if the refrigerator is running, it is possible to further check whether the ambient noise level in the vehicle is higher than the refrigerator noise level. If the ambient noise level in the vehicle is higher than the refrigerator noise level, then noise reduction for the refrigerator is not necessary.

[0114] Conversely, if the ambient noise level in the vehicle is no greater than the noise level of the refrigerator, the ADSP can output and play the first noise-reduced signal based on the first noise signal; or, the SOC can determine the first noise-reduced signal based on the first operating status information of the refrigerator and send it to the ADSP for playback.

[0115] When playing the first noise-reduced signal, the system can check whether the noise reduction meets expectations based on user ratings; if not, it can re-check whether the refrigerator is running.

[0116] In this embodiment of the invention, the presence of passengers in each area of ​​the vehicle is detected; a first noise signal from the refrigerator in the area where passengers are present is acquired; a first noise reduction signal is determined for each area based on the first noise signal; a second noise signal from the external environment is acquired; a noise reduction operation is determined based on the first and second noise signals; when a noise reduction operation is determined based on the first and second noise signals, the determined first noise reduction signal is played for each area. Through this embodiment of the invention, noise reduction can be performed only in areas with passengers, thereby reducing noise reduction energy consumption.

[0117] In addition, when environmental noise has a significant impact on passengers, not targeting the refrigerator's noise reduction can also reduce noise reduction energy consumption.

[0118] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.
