[0062] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0063] The sound insulation device provided by the present application can adjust its own working frequency according to the actual situation of the noise source, so as to improve the sound insulation and noise reduction effect.

[0064] Embodiment 1

[0065] Figure 1 The structural schematic diagram of the sound insulation device provided by the embodiment of the present invention is shown.

[0066] See Figure 1 , the embodiment of the present invention provides a sound insulation device, and the sound insulation device includes:

[0067] A noise sensor 101, a controller 102, an electromagnetic field generator 103, and a magnetorheological fluid matrix 104;

[0068] The noise sensor 101 and the electromagnetic field generator 103 are respectively communicatively connected to the controller 102;

[0069] The noise sensor 101 is used to detect noise data and send the noise data to the controller 102;

[0070] The controller 102 is used to generate a generator control instruction according to the noise data and send the generator control instruction to the electromagnetic field generator 103;

[0071] The electromagnetic field generator 103 is used to generate a corresponding electromagnetic field according to the generator control instruction;

[0072] The magnetorheological fluid matrix 104 is used to change the mass distribution of the sound insulation device under the influence of the electromagnetic field so as to reduce the current noise.

[0073] Once the specific form of the mass distribution of the traditional sound insulation and noise reduction device is determined, its effective working frequency is also fixed. However, in some application scenarios, the peak frequency of the noise will change, and at this time, the noise reduction effect of the sound insulation and noise reduction device will decrease significantly.

[0074] The sound insulation device provided by the embodiment of the present invention can adjust its own mass distribution according to the actual situation of the noise, so as to adjust the noise reduction working frequency of the sound insulation device, adapt to different noise peak frequencies, and improve the overall sound insulation and noise reduction effect.

[0075] In a specific example, the sound insulation device provided by the embodiment of the present invention can be applied to the noise reduction of the variable frequency compressor of a refrigeration device.

[0076] In some embodiments, the magnetorheological fluid matrix includes a thin film structure.

[0077] In some embodiments, the magnetorheological fluid matrix includes at least one magnetorheological fluid unit, and each magnetorheological fluid unit includes at least two interconnected magnetorheological fluid chambers;

[0078] The magnetorheological fluid chambers are configured to contain magnetorheological fluid, and the magnetorheological fluid flows within the magnetorheological fluid chambers under the influence of the electromagnetic field to change the mass distribution of the sound insulation device.

[0079] Figure 2 The schematic structural diagram of the magnetorheological fluid matrix in the sound insulation device provided by the embodiment of the present invention is shown.

[0080] See Figure 2 , in a specific example, the magnetorheological fluid matrix is a thin film structure. Magnetorheological fluid units serving as additional mass are uniformly distributed on the thin film structure. Each magnetorheological fluid unit includes two magnetorheological fluid chambers, and the magnetorheological fluid can flow between the two chambers.

[0081] Among them, the flow position of the magnetorheological fluid between the magnetorheological fluid chambers is controlled by adjusting the electromagnetic field of the controller.

[0082] Optionally, the number of magnetorheological fluid units is set according to the size of the thin film structure. Since there are at least two choices for the position of the magnetorheological fluid in each magnetorheological fluid unit, when the number of magnetorheological fluid units is n, there are at least 2 n types of mass distribution modes on the thin film structure.

[0083] Based on the diverse mass distribution modes, the working frequency of the sound insulation device can be fully adjusted to adapt to different noise sources.

[0084] Figure 3 The schematic diagram of the sound insulation effect calculation model of the sound insulation device provided by the embodiment of the present invention is shown.

[0085] See Figure 3 , the incident sound wave passes through the thin film sound insulation device with additional mass and then transmits out, and this process realizes the function of sound insulation and noise reduction.

[0086] Specifically, the thin film and the additional mass are in the center of the acoustic waveguide, Figure 3 the left end in

[0087] STL = 10log 10 (P in / P out )

[0088] where STL is the sound transmission loss, P in is the incident sound wave power, and P out is the transmitted sound wave power.

[0089] Figure 4 FIG. shows an example diagram of the mass distribution of the magnetorheological fluid matrix in the sound insulation device provided by the embodiment of the present invention.

[0090] Refer to Figure 4 , the magnetorheological fluid matrix provided by the embodiment of the present invention can exhibit different mass distributions based on the change of the electromagnetic field.

[0091] Specifically, the magnetorheological fluid can flow in the connected magnetorheological fluid cavity to achieve different mass distributions under the condition that the additional mass remains unchanged.

[0092] Figure 5 FIG. shows the sound insulation effect corresponding to the mass distribution mode of the magnetorheological fluid matrix in the sound insulation device provided by the embodiment of the present invention.

[0093] Refer to Figure 5 , under different mass distribution modes, the peak values of the sound transmission loss of the sound insulation device correspond to different frequencies, that is, the low-frequency noise reduction working frequencies of different mass distributions are different.

[0094] In summary, the sound insulation device provided by the embodiment of the present invention can control the mass distribution characteristics of the magnetorheological fluid on the film by controlling the electromagnetic field, can adjust the working frequency of the film-type sound insulation cover, make the resonance frequency of the film structure equal to the main peak frequency of the noise, and achieve the active isolation of the corresponding frequency noise.

[0098] The sound insulation cover is a cavity structure, and the cavity is used to accommodate the noise source;

[0099] The cover wall of the sound insulation cover includes an inner layer and an outer layer. The inner layer includes the magnetorheological fluid matrix of the sound insulation device, and the outer layer includes the porous material.

[0100] Specifically, the porous material can absorb medium and high-frequency noise, and the sound insulation device is used to block medium and low-frequency noise.

[0101] Embodiment 3

[0102] The embodiment of the present invention provides a refrigerating range hood, and the refrigerating range hood includes a compressor and the sound insulation cover as described above;

[0104] Embodiment 4

[0105] Figure 7 Shows a schematic diagram of the implementation process of a sound insulation device control method provided by an embodiment of the present invention.

[0106] See Figure 7 , the sound insulation device control method provided by an embodiment of the present invention is applied to the sound insulation device as described above, and may include steps 201 to 203.

[0107] Step 201: Obtain target noise data, where the target noise data includes first frequency data of the target noise;

[0108] Step 202: Determine the electromagnetic field distribution mode based on the pre-stored first correspondence and the first frequency data; the first correspondence is the correspondence between the first frequency data and the electromagnetic field distribution mode;

[0109] Step 203: Adjust the electromagnetic field of the sound insulation device based on the electromagnetic field distribution mode to change the mass distribution mode of the sound insulation device.

[0110] In some embodiments, the sound insulation device control method further includes:

[0111] Detect the operating frequency corresponding to the mass distribution mode of the first quantity of the sound insulation device; the operating frequency is the main noise reduction frequency of the sound insulation device;

[0112] Establish the first correspondence based on the operating frequency corresponding to the mass distribution mode of the first quantity and the electromagnetic field distribution mode.

[0113] In some embodiments, establishing the first correspondence based on the operating frequency corresponding to the mass distribution mode of the first quantity and the electromagnetic field distribution mode further includes:

[0114] Train a neural network based on the mass distribution mode of the first quantity;

[0115] Establish the first correspondence based on the trained neural network.

[0116] In some embodiments, after adjusting the electromagnetic field of the sound insulation device based on the electromagnetic field distribution mode, the method further includes:

[0117] Obtain transmitted sound wave data, where the transmitted sound wave data includes second frequency data of the transmitted sound wave;

[0118] Adjust the electromagnetic field distribution mode based on the second frequency data.

[0119] Figure 8It shows another schematic implementation flow diagram of the sound insulation device control method provided by the embodiments of the present invention.

[0120] Refer to Figure 8 , in a specific example, the implementation process of the sound insulation device control method provided by the embodiments of the present invention is as follows.

[0121] First, the incident sound wave signal is collected by the sound sensor and sent to the controller, and the controller calculates the mass distribution characteristics and controls the electromagnetic field change according to the calculation result.

[0122] The change in the electromagnetic field will cause a change in the mass distribution. The transmitted sound wave signal is collected by the sound sensor again and fed back to the controller.

[0123] The above process of the controller calculating the mass distribution characteristics according to the incident sound wave signal and controlling the electromagnetic field to change the mass distribution is executed cyclically, so as to achieve adaptive noise reduction under the condition of the compressor frequency change.

[0124] In a specific example, first, through simulation analysis or experimental testing, the effective noise reduction frequencies corresponding to a considerable part of the mass distribution forms are obtained, and this is used as the training database for machine learning. Finally, a control algorithm that can solve the specific mass distribution form according to the incident frequency is trained.

[0125] During the noise reduction process, the incident sound wave signal is collected by the sound sensor and transmitted to the controller as a reference signal. The controller uses the control algorithm obtained by machine learning training to give the specific form of the mass distribution on the thin film according to the incident sound wave frequency. Then, through the control circuit, the magnetorheological fluid is migrated under the action of the electromagnetic field to realize the active modulation of the mass distribution, so that the effective frequency of the thin film noise reduction structure is equal to the incident sound wave frequency, thereby realizing sound wave blocking. At the same time, the sound sensor will also collect the transmitted sound wave signal as an error signal and feed it back to the controller to further improve the real-time noise reduction effect of the sound insulation cover.

[0126] In some embodiments, the method provided by the present invention can be applied to the noise reduction of a compressor, especially the compressor in a refrigeration type range hood. There is medium and low frequency noise with frequency variation due to temperature change in the noise of such compressors. The method provided by the embodiments of the present invention adaptively adjusts the additional mass distribution of the sound insulation cover according to the current noise frequency, and can effectively reduce the medium and low frequency noise with unstable frequency.
