[0014] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0015] It should be noted that, in the description of this application, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence.

[0016] In related technologies, hard disks play a core role in data storage and ensuring service stability in servers. With the continuous improvement of server performance and the increase in hard disk storage density and read and write speeds, the noise problem generated during hard disk operation has become increasingly prominent and has a greater impact on the hard disk. The noise will cause great damage to the read and write performance of the hard disk.

[0017] Common ways to reduce noise on server hard disks are physical noise reduction, such as wrapping sound insulation materials around the hard disk, adding shock-absorbing pads, etc. However, these physical noise reduction methods have many limitations. On the one hand, the use of sound insulation materials will increase the cost and volume of the server, which is not conducive to the miniaturization and high-density integration of the server. On the other hand, physical noise reduction methods have limited noise reduction effects on high-frequency noise and complex noise environments, and cannot effectively improve the read and write performance of the hard disk.

[0018] In order to solve the above technical problems, the present application provides a hard disk component noise reduction device, method, equipment and storage medium, which can effectively improve the read and write performance of the hard disk.

[0019] Combine the following Figures 1 to 17 , describing an embodiment of the present application.

[0020] According to an embodiment of the present application, on the one hand, a hard disk noise reduction method is provided, which is applicable to a data processing device, wherein the data processing device includes at least one hard disk component 4, such as Figures 1 to 4 As shown, it includes at least one sensor module 1, a signal processing module 2 and at least one speaker module 3, and the specific scheme is as follows.

[0021] It should be noted that if Figure 1 As shown, the data processing device may be a server or a personal computer host or other device having data processing functions and a hard disk component 4 .

[0022] like Figure 3 As shown, the sensor module 1 is used to be arranged in the data processing device to obtain the vibration signal of the hard disk assembly 4 and the noise signal at the location where the hard disk assembly 4 is located; specifically, the number of the sensor modules 1 can be one or more, corresponding to the number of the hard disk assemblies 4. When there are multiple hard disk assemblies 4 inside the data processing device, the number of the sensor modules 1 is multiple, which are used to respectively detect the vibration signals of each hard disk assembly 4 and the noise signals at the location where the hard disk assembly 4 is located.

[0023] The signal processing module 2 is connected to the sensor module 1 via a wiring harness, and can also be connected via a wireless signal (such as Bluetooth, wireless network, etc.); an anti-noise model is set in the signal processing module 2 to process the vibration signal and the noise signal and output the anti-noise signal.

[0024] It should be noted that the anti-noise signal output by the signal processing module 2 can release anti-noise that can at least partially offset the vibration of the hard disk assembly 4 and the noise at the location where the hard disk assembly 4 is located.

[0025] The speaker module 3 is used to be set inside the data processing device and faces the hard disk assembly 4. The speaker module 3 is connected to the signal processing module 2 through a wiring harness, and can also be connected through a wireless signal (such as Bluetooth, wireless network, etc.). The speaker module 3 is used to output anti-noise according to the anti-noise signal input by the data processing module.

[0026] Specifically, the sound-speaking module 3 can adopt a speaker, preferably a speaker with a semi-open speaker structure. The semi-open "speaker-type" design can release the audio of the anti-noise signal more excellently, and can achieve a better release effect against noise, thereby improving the offset of the vibration of the hard disk assembly 4 and the noise at its location, and can reduce the number of corrections for anti-noise generation.

[0027] like Figure 3 As shown, the number of speaker modules 3 can be one or more, corresponding one to one with the hard disk assembly 4. When there are multiple hard disk assemblies 4 inside the data processing device, the number of speaker modules 3 is multiple, which are used to send anti-noise to each hard disk assembly 4 respectively.

[0028] In the specific use process, such as Figures 1 to 4As shown, the data processing device takes a server as an example. Eight hard disk components 4 are installed in the server housing. Then, eight sensor modules 1, signal processing modules 2 and eight speaker modules 3 need to be installed in the server housing.

[0029] Specifically, the signal processing module 2 includes a processor and a memory. The processor adopts a high-performance digital signal processor with powerful signal processing capabilities and fast computing speed. The memory is connected to the processor and is used to store the anti-noise model. The memory can adopt a high-speed flash memory chip to ensure fast reading and writing of data and stability of storage.

[0030] like Figure 3 As shown, eight sensor modules 1 are respectively arranged around two hard disk assemblies 4 to respectively obtain the vibration signals of the eight hard disk assemblies 4 and the noise signals at the locations of the eight hard disk assemblies 4, and transmit them to the processor in the signal processing module 2. The processor calls the anti-noise model in the memory to process the vibration signals and noise signals corresponding to the eight hard disk assemblies 4 respectively, and obtain the anti-noise signals corresponding to the eight hard disk assemblies 4.

[0031] like Figure 3 As shown, eight speaker modules 3 face eight hard disk assemblies 4 respectively, and receive the anti-noise signals corresponding to the eight hard disk assemblies 4 respectively, to release corresponding anti-noise to the eight hard disk assemblies 4 respectively, so as to offset the vibration of the eight hard disks and the noise at their locations.

[0032] In this embodiment, the sensor module 1 is used to obtain the vibration signal of the hard disk assembly 4 and the noise signal at the location where the hard disk assembly 4 is located, and the signal processing module 2 organically combines the vibration signal of the hard disk assembly 4 and the noise signal at the location, outputs an anti-noise signal, and releases it toward the hard disk assembly 4 through the speaker module 3, thereby offsetting the vibration of the hard disk and the noise at its location, thereby reducing the vibration at the connection between the hard disk assembly 4 and the read-write module, thereby improving the signal transmission stability at the plug interface of the hard disk assembly 4, thereby improving the read-write performance of the hard disk, and reducing the incidence of data distortion.

[0033] In one embodiment, the sensor module 1 includes a vibration detection unit and a noise detection unit. The vibration detection unit is provided with a probe 17, which is used to contact the surface of the hard disk assembly 4 to obtain a vibration signal; the noise detection unit is arranged at a position close to the hard disk assembly 4 to obtain a noise signal.

[0034] It should be noted that the vibration detection unit and the noise detection unit can be two separate parts to respectively implement vibration detection and noise detection; or they can be two parts of an integral component, that is, the sensor module 1 is a composite sensor.

[0035] Specifically, the noise detection unit may adopt a microphone array noise sensor; the vibration detection unit may adopt a vibration detection sensor, both of which are existing products and can be purchased on the market.

[0036] During specific use, the probe 17 of the vibration detection unit can be brought into contact with the surface of the hard disk assembly 4 to detect the vibration signal of the hard disk assembly 4; if the noise detection unit and the vibration detection unit are two separate parts, the noise detection unit is arranged around the hard disk assembly 4 to obtain the noise signal at the location of the hard disk assembly 4; if the noise detection unit and the vibration detection unit are an integral component, there is no need to arrange them separately.

[0037] In this embodiment, the sensor module 1 includes a vibration detection unit and a noise detection unit. The vibration signal of the hard disk is obtained by contacting the hard disk assembly 4 with the probe 17 on the vibration detection unit. The noise detection unit is arranged at a position close to the hard disk assembly 4 to obtain the noise signal at the position where the hard disk assembly 4 is located. The structure is simple and the reliability is high.

[0038] In a specific embodiment, Figures 5 to 7 As shown, the sensor module 1 includes a substrate 11, a sleeve 12, a vibration signal conversion component 13, a slider 14, an isolation block 15, a noise detection component 16, a probe 17 and a spring 18, and the specific scheme is as follows.

[0039] like Figure 5 As shown, the substrate 11 is used to be connected inside the data processing device. Specifically, the substrate 11 is a circuit board. A connector is provided on the substrate 11 to be connected to the signal processing module 2. The substrate 11 is fixed inside the data processing device by bolts. like Figures 9 and 10 As shown, the sleeve 12 is a cylinder made of plastic material, a through hole 121 is provided at the first end of the sleeve 12, and a receiving groove 122 is provided at the second end of the sleeve 12. The through hole 121 is connected to the receiving groove 122. Specifically, the through hole 121 is a circular hole, and the cross-section of the receiving groove 122 is rectangular or square.

[0040] like Figures 5 to 7 As shown, the vibration signal conversion component 13 is specifically a vibration sensor. The vibration signal conversion component 13 is set on the substrate 11 by welding or bolting, and is electrically connected to the substrate 11. The vibration receiving part of the vibration signal conversion component 13 is inserted into the receiving groove 122. Specifically, a hook is provided on the edge of the receiving groove 122 to limit a part of the vibration signal conversion component 13 in the receiving groove 122. It should be explained that the vibration signal conversion component 13 is used to receive vibration and convert the vibration into an electrical signal; the vibration receiving part on the vibration signal conversion component 13 is used to contact the slider 14 that transmits vibration to receive the vibration.

[0041] like Figure 7 As shown, the slider 14 is slidably disposed in the receiving groove 122 and is located between the through hole 121 and the vibration signal conversion component 13 , and is used to contact the vibration receiving portion of the vibration signal conversion component 13 .

[0042] like Figure 11 to Figure 12 As shown, the isolation block 15 is specifically a rigid plastic block, that is, a block with a small elastic compression amount, specifically an ABS block (acrylonitrile-butadiene-styrene copolymer, a thermoplastic engineering plastic) or a PA66 block (polyamide 66, or nylon 66, a semi-crystalline thermoplastic engineering plastic formed by condensation of adipic acid and hexamethylenediamine); an annular avoidance groove 151 is provided on the end surface of the isolation block 15 facing the sleeve 12, a step groove 152 is provided on the isolation block 15, a through hole 153 is provided at the bottom of the step groove 152, the through hole 153, the step groove 152 and the accommodating groove 122 are coaxially arranged, and the isolation block 15 is a sound-transmitting block.

[0043] Specifically, the sound-transmitting block is a block with good sound-transmitting performance, such as an acrylic block, etc., or it can be other blocks with less effect on noise penetration.

[0044] like Figure 8 As shown, the noise detection component 16 includes a plurality of noise sensors 161 and a circuit board 162, wherein the plurality of noise sensors 161 are arranged on the circuit board 162, and an avoidance hole 1621 is provided on the circuit board 162. The circuit board 162 is arranged between the isolation block 15 and the sleeve 12, and the plurality of noise sensors 161 are located in the avoidance groove 151. Preferably, the plurality of noise sensors 161 are arranged in a circular array; the circuit board 162 is connected to the substrate 11 via a PFC (Flexible Printed Circuit) to transmit noise signals.

[0045] like Figure 7 As shown, the probe 17 is a plastic part. The first end of the probe 17 is used to abut against the hard disk assembly 4. At least a part of the probe 17 can enter the stepped groove 152. The other end of the probe 17 slides through the through hole 153, the avoidance hole 1621 and the through hole 121 to be connected with the slider 14. A limiting portion 171 is provided on the probe 17. Specifically, the limiting portion 171 is a mushroom-shaped block. The probe 17 is connected to the slider 14 through a snap-fit ​​structure.

[0046] like Figure 7As shown, the spring 18 is sleeved on the probe 17 and is located in the stepped groove 152 , and two ends of the spring 18 abut against the limiting portion 171 and the inner bottom of the stepped groove 152 respectively.

[0047] In the specific assembly process, such as Figure 7 As shown, the spring 18 is placed in the stepped groove 152, the circuit board 162 of the noise detection component 16 is placed between the isolation block 15 and the sleeve 12, and then the second end of the probe 17 passes through the spring 18, the through hole 153, the avoidance hole 1621 and the via 121, and is connected to the slider 14. The spring 18 is in a compressed state, and under the action of the spring 18, the isolation block 15 and the noise detection component 16 are fixed on the first end of the sleeve 12.

[0048] The vibration signal conversion component 13 is fixed on the substrate 11 , and the vibration receiving part of the vibration signal conversion component 13 is inserted into the receiving groove 122 to contact the slider 14 ; and the FPC connected to the circuit board 162 is connected to the substrate 11 by bonding.

[0049] In this embodiment, the noise detection component 16 is clamped between the isolation block 15 and the sleeve 12 by means of a probe 17, an isolation block 15, a spring 18 and a slider 14, so that the noise sensor 161 is located in the avoidance groove 151. This not only realizes the vibration contact between the vibration signal conversion component 13 and the hard disk assembly 4, but also integrates the noise sensor 161 on the sleeve 12. The structure is simple and compact, and is convenient for arrangement in data processing equipment with limited space.

[0050] In one embodiment, Figure 3 and Figure 4 As shown, the probe 17 on the sensor module 1 is used to abut the detection surface 41 on the hard disk assembly 4 and is close to the plug connector 42 of the hard disk assembly 4 to obtain a vibration signal, wherein the detection surface 41 is the surface of the hard disk assembly 4 where the plug connector 42 is set.

[0051] Specifically, the distance between the probe 17 and the plug connector 42 is 2 mm to 8 mm; the probe 17 is along the thickness direction of the data processing device, and the probe 17 is located directly above the plug connector 42 .

[0052] In this embodiment, by bringing the probe 17 into contact with the detection surface 41 on which the plug connector 42 is provided on the hard disk assembly 4, and moving the probe 17 closer to the plug connector 42, the vibration signal and noise signal at the position of the plug connector 42 of the hard disk assembly 4 can be obtained more realistically, thereby facilitating the acquisition of a more effective anti-noise signal to effectively offset the vibration and noise at the plug connector 42 of the hard disk assembly 4, and reduce the vibration amplitude at the plug connector 42 of the hard disk assembly 4, thereby further improving the signal transmission stability at the plug interface of the hard disk assembly 4, thereby improving the read and write performance of the hard disk, and reducing the incidence of data distortion.

[0053] In one embodiment, Figure 3 and Figure 4 As shown, the speaker module 3 faces the detection surface 41 and is away from the plug connector 42 on the hard disk assembly 4. Specifically, the distance between the speaker module 3 and the detection surface 41 is 1mm~3mm, and the distance between the speaker module 3 and the plug connector 42 is 40mm~60mm, preferably 50mm.

[0054] And / or, the speaker module 3 is connected to the data processing device via a shock-absorbing adhesive strip.

[0055] During specific use, by placing the speaker module 3 toward the detection surface 41 and away from the plug connector 42, when the speaker module 3 emits anti-noise, the anti-noise can be transmitted to the hard disk assembly 4 and the surroundings of the hard disk assembly 4, thereby offsetting the vibration of the hard disk assembly 4 and the noise at the location of the hard disk assembly 4. At the same time, it can avoid the vibration of the speaker module 3 itself from having a greater impact on the vibration of the plug connector 42, thereby aggravating the vibration of the plug connector 42, thereby improving the anti-noise weakening effect on the vibration of the plug connector 42, thereby improving the read and write performance of the hard disk assembly 4.

[0056] The speaker module 3 is connected to the data processing device via a shock-absorbing adhesive strip, which can further prevent the vibration of the speaker module 3 itself from having a significant impact on the vibration of the plug connector 42.

[0057] According to an embodiment of the present application, in a second aspect, a data processing device is provided, such as Figures 1 to 3 As shown, it includes a chassis 5, a read-write module 6, at least one hard disk assembly 4 and a hard disk assembly noise reduction device in any one embodiment of the first aspect, and the specific scheme is as follows.

[0058] like Figure 1 As shown, the chassis 5 is a metal shell made of metal or plastic.

[0059] like Figure 1 As shown, the read-write module 6 is disposed in the chassis 5 , and the read-write module 6 is connected to a socket. Specifically, the read-write module 6 may be a mainboard with data processing function, or a processor, etc.

[0060] The hard disk assembly 4 is plugged into the chassis 5. A plug connector 42 is provided on the hard disk assembly 4. The plug connector 42 is plugged into the socket. Specifically, the plug connector 42 is a SATA interface (STTA, Serial Advanced Technology Attachment, serial advanced technology attachment), or a PCIe interface (PCIe, Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard), etc. The socket matches the plug connector 42.

[0061] like Figures 1 to 3 As shown, the noise reduction device of the hard disk assembly 4 is arranged in the chassis 5 , the sensor module 1 is used to obtain the vibration signal of the hard disk assembly 4 and the noise signal at the location of the hard disk assembly 4 ; the speaker module 3 faces the hard disk assembly 4 .

[0062] It should be noted that the number of hard disk components 4 is the same as the number of sensor modules 1 and speaker modules 3 .

[0063] Specifically, the data processing device may be a server, a personal computer host, or other device that has data processing capabilities and a hard disk component 4 .

[0064] In this embodiment, since the data processing device includes the hard disk assembly noise reduction device, it has the same technical effect as the hard disk assembly noise reduction device, and will not be described in detail here.

[0065] In one embodiment, Figure 1 As shown, there are multiple hard disk assemblies 4, multiple sensor modules 1, and multiple speaker modules 3. Each hard disk assembly 4 is respectively arranged corresponding to a sensor module 1 and a speaker module 3, that is, a sensor module 1 is arranged around each hard disk assembly 4 to detect its vibration signal and the noise signal at its location, and a speaker module 3 is used to eliminate its vibration and the surrounding noise signal.

[0066] Multiple sensor modules 1 and multiple speaker modules 3 are connected to the processing module through a wiring harness. The signal processing module 2 can transmit the anti-noise signal generated according to the vibration signal and noise signal transmitted by the sensor module 1 to the speaker module 3 corresponding to the sensor module 1.

[0067] like Figures 1 to 3 As shown, multiple hard disk assemblies 4 are arranged in two rows, the plug connectors 42 on the two rows of hard disk assemblies 4 are arranged opposite to each other, and the signal processing module 2, multiple sensor modules 1 and multiple speaker modules 3 are all arranged between the two rows of hard disk assemblies 4.

[0068] In a preferred embodiment, Figures 2 to 3As shown, the data processing device further includes a tray 7 , which is plugged into the chassis 5 , and the hard disk assembly 4 and the noise reduction device of the hard disk assembly 4 are both arranged on the tray 7 .

[0069] In the specific use process, such as Figures 1 to 3 As shown, the data processing device takes a server as an example. Eight hard disk components 4 are installed in the server case, so eight sensor modules 1, signal processing modules 2 and eight speaker modules 3 need to be installed in the server case; specifically, the signal processing module 2 includes a processor and a memory; the sensor module 1 uses a vibration detection unit and a noise detection unit as an integrated sensor.

[0070] like Figure 1 As shown, eight hard disk assemblies 4 are installed on the tray 7 in two rows, that is, four hard disk assemblies 4 are arranged side by side in each row, and the two rows of hard disk assemblies 4 are arranged opposite to each other, that is, the plug connectors 42 on the hard disk assemblies 4 in one row face the hard disk assemblies 4 in the other row, that is, the detection surface 41 of the hard disk assemblies 4 in one row is arranged opposite to the detection surface 41 of the hard disk assemblies 4 in the other row.

[0071] like Figure 3 As shown, eight sensor modules 1 are arranged in the area between two rows of hard disk assemblies 4 and are fixed to the case by screws. The probes 17 of the eight sensor modules 1 are respectively abutted against the detection surfaces 41 of the eight hard disk assemblies 4, and along the thickness direction of the chassis 5, the sensor modules 1 are located directly above the plug connector 42.

[0072] like Figure 3 As shown, eight speaker modules 3 are arranged in the area between two rows of hard disk assemblies 4 , facing the eight hard disk assemblies 4 respectively and away from the plug connectors 42 of the corresponding hard disk assemblies 4 . The processor and the memory are installed between two rows of hard disk assemblies 4 , the memory is connected to the processor, and the processor is connected to the eight sensor modules 1 and the eight speaker modules 3 .

[0073] In this embodiment, multiple hard disk assemblies 4 are arranged in two rows, and multiple sensor modules 1, multiple speaker modules 3 and signal processing modules 2 are arranged between the two rows of hard disk assemblies 4. The structure is compact, which can save layout space and improve the compactness of the data processing equipment.

[0074] In this embodiment, the active noise reduction principle is adopted to effectively reduce the noise of various frequencies generated when the server hard disk component 4 is running, especially for high-frequency noise and complex noise environment. Compared with the traditional physical noise reduction method, the noise reduction effect is improved by more than 30%.

[0075] Moreover, the device has a simple structure and does not increase the volume of excessive hardware, which is conducive to the miniaturization and high-density integration of the server.

[0076] At the same time, it is adaptive and can automatically adjust the parameters of the anti-noise signal according to the changes in the noise signal when the hard disk is running, ensuring good noise reduction effects under different working conditions.

[0077] Thirdly, by real-time monitoring and adjusting the noise reduction effect, the overall performance and stability of the server can be effectively improved, the service life of the hard disk can be extended, and the user experience can be improved.

[0078] According to an embodiment of the present application, in a third aspect, a method for reducing noise of a hard disk assembly 4 is provided, which is applicable to a hard disk assembly noise reduction device in any one of the embodiments in the first aspect, such as Fig.13 As shown, the steps include: S1: Acquire a vibration signal of the hard disk assembly and a noise signal at a location where the hard disk assembly is located.

[0079] Specifically, the vibration signal and noise signal of each hard disk assembly 4 are acquired through the sensor module 1 .

[0080] S2: Input the vibration signal and the noise signal into the anti-noise model for processing to obtain the anti-noise signal.

[0081] Specifically, the anti-noise model is a pre-screened processing program, and may also be a model obtained by training through a system such as a convolutional neural network.

[0082] The specific process of obtaining the anti-noise model through convolutional neural network training is as follows.

[0083] A batch of samples is obtained, and the samples are divided into training samples and verification samples; the input features of the samples are the vibration signals and noise signals of the hard disk components obtained; the output features are: the corresponding anti-noise.

[0084] The training samples are input into the convolutional neural network for training to obtain a preliminary anti-noise model, and then the verification samples are input into the preliminary anti-noise model for verification. The preliminary anti-noise model is adjusted to finally obtain the anti-noise model.

[0085] S3: Inputting an anti-noise signal to the speaker module so that the speaker module outputs anti-noise.

[0086] In this embodiment, the sensor module 1 is used to obtain the vibration signal of the hard disk assembly 4 and the noise signal at the location of the hard disk, and the signal processing module 2 organically combines the vibration signal of the hard disk assembly 4 and the noise signal at the location, outputs an anti-noise signal, and releases it toward the hard disk assembly 4 through the speaker module 3, thereby offsetting the vibration of the hard disk and the noise at its location, thereby reducing the vibration at the connection between the hard disk assembly 4 and the read-write module, thereby improving the signal transmission stability at the plug interface of the hard disk assembly 4, thereby improving the read-write performance of the hard disk, and reducing the incidence of data distortion.

[0087] In one embodiment, Fig.16 As shown, the steps are: inputting the vibration signal and the noise signal into the anti-noise model for processing to obtain the anti-noise signal, including: S21: Synchronously superimpose the vibration signal and the noise signal to obtain a superimposed signal.

[0088] Specifically, the synchronous superposition of the vibration signal and the noise signal can be processed by linear superposition, weighted superposition or Fourier transform superposition.

[0089] S22: Perform spectrum analysis and time domain analysis on the superimposed signal to obtain the amplitude, frequency and phase of the superimposed signal.

[0090] S23: outputting an anti-noise signal according to the amplitude, frequency and phase of the superimposed signal, wherein the amplitude and frequency of the anti-noise signal are respectively the same as the amplitude and frequency of the superimposed signal, and the phase of the anti-noise signal is opposite to the phase of the superimposed signal.

[0091] In this embodiment, the vibration signal and the noise signal are first superimposed to obtain a superimposed signal, and then the superimposed signal is subjected to spectrum analysis and time domain analysis to obtain the amplitude, frequency and phase of the superimposed signal, so as to output an anti-noise signal with a phase opposite to that of the superimposed signal but the same frequency and amplitude as the superimposed signal. The method is simple and effective.

[0092] In one embodiment, Fig.14 As shown, the hard disk assembly noise reduction method also includes the steps of: S4: Obtain a residual noise signal, wherein the residual noise signal is a vibration signal and a noise signal detected by the sensor module after the speaker module releases the anti-noise function.

[0093] S5: Determine whether the remaining noise signal reaches a preset standard value.

[0094] S6: If not, adjust the vibration signal and the noise signal according to the remaining noise signal, obtain a new vibration signal and a new noise signal, and input them into the anti-noise model for processing until the remaining noise signal meets the preset standard value.

[0095] In this embodiment, the residual noise signal is obtained and it is determined whether the residual noise signal meets the requirements. If the output result is no, the vibration signal and the noise signal are adjusted according to the residual noise signal, and a new anti-noise signal is output again until the obtained residual noise signal meets the requirements; thereby, the anti-noise signal can be optimized and the read and write performance of the hard disk assembly can be further improved.

[0096] In a specific embodiment, the step of adjusting the vibration signal and the noise signal according to the residual noise signal comprises the steps of: The vibration signal in the remaining noise signal is synchronously superimposed with the vibration signal, and the noise signal in the remaining noise signal is synchronously superimposed with the noise signal to obtain a new vibration signal and a new noise signal.

[0097] In this embodiment, the original vibration signal and noise signal are optimized by synchronously superimposing the vibration signal in the remaining noise signal with the vibration signal, and synchronously superimposing the noise signal in the remaining noise signal with the noise signal. The solution is simple, effective and fast.

[0098] In one embodiment, Fig.15 As shown, the hard disk assembly noise reduction method also includes the steps of: S7: Acquire an operation noise signal, wherein the operation noise is the noise generated by the data processing device during operation.

[0099] S8: Determine whether the running noise signal reaches the dust removal standard value; S9: If yes, output a maintenance signal.

[0100] In this embodiment, by judging whether the operating noise reaches the dust removal standard, the maintenance personnel are reminded to perform maintenance on the data processing equipment, so that problems can be discovered in time and the operating efficiency of the data processing equipment can be improved.
