[0037] To make the above objects, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] The embodiment of this application provides an evaluation method for the deformation of a waterproof film. In the first embodiment of the evaluation method for the deformation of the waterproof film in this application, refer to Figure 1 , which is applied to the evaluation device for the deformation of the waterproof film. The method includes:

[0040] Step S10: Determine the maximum pressure difference acting on the waterproof film when the speaker is working, and determine the material parameters, fixing method, and initial structure of the waterproof film;

[0041] Step S20: Input the maximum pressure difference, the fixing method, the material parameters, and the initial structure into a preset simulation model, and determine the simulated deformation amount of the waterproof film;

[0042] Step S30: If the simulated deformation amount is greater than a preset critical value, optimize at least one of the initial structure, the fixing method, and the material parameters of the waterproof film.

[0043] In this embodiment, the targeted application scenario is as follows: Currently, when the speaker in the vehicle is working, the sound vibration drives the vibration of the air in the surrounding environment. The vibration of the air drives the waterproof film to vibrate and deform, and the vibrating waterproof film will emit noise, which interferes with the working speaker and affects the user's auditory experience. That is, there is a problem that when the speaker is working, it will cause the waterproof film to vibrate and deform, and the vibration and deformation of the waterproof film will bring noise to the speaker.

[0044] As an example, as Figure 2 shown, it is a schematic diagram of a car door, including the speaker and the waterproof film pre-installed on the car door. When the speaker on the car door works, it drives the waterproof film to vibrate. When the vibration amount of the waterproof film reaches a certain level, it will emit noise, bringing noise to the working speaker.

[0045] As an example, when the speaker is working, it generates a pressure difference on the surface of the waterproof film. Take the maximum pressure difference, simply referred to as the maximum pressure differential.

[0046] The purpose of this embodiment is to improve the problem that when the speaker is working, it causes the waterproof film to vibrate and deform, and the vibration and deformation of the waterproof film bring noise to the speaker.

[0047] In this embodiment, the evaluation method for the deformation of the waterproof film is applied to the evaluation device for the deformation of the waterproof film.

[0048] The specific steps are as follows:

[0049] Step S10, determine the maximum pressure differential acting on the waterproof film when the speaker is working, and determine the material parameters, fixing method, and its initial structure of the waterproof film;

[0050] In this embodiment, the maximum pressure differential fundamentally comes from the speaker. Therefore, the maximum pressure differential is related to the speaker.

[0051] As an example, when the speaker is working, the composite basin on the surface of the speaker vibrates up and down, affecting the air volume in the car door cavity. According to the ideal gas state formula PV = nRT, the air pressure can be determined based on the volume, where P is the air pressure, V is the gas volume, n is the amount of substance of air, R is the universal gas constant, and T is the temperature. Determine the maximum change in the air volume in the car door cavity, and then the maximum pressure differential can be directly determined.

[0052] In step S10, the steps for determining the maximum pressure differential acting on the waterproof film when the speaker is working include steps S11 - S12:

[0053] Step S11, obtain the maximum change in the air volume in the car door cavity when the speaker is working;

[0054] As an example, obtain the maximum change in the air volume in the car door cavity when the speaker is working.

[0055] As an example, the maximum change in the air volume inside the car door is related to the performance parameters of the speaker. The performance parameters of the speaker include the sound power Pa, the resonance frequency f0, the effective radiation diameter Deff of the composite diaphragm, etc. Based on the above performance parameters, the maximum theoretical change in the air volume inside the car door can be calculated.

[0056] Before step S11 of obtaining the maximum change in the air volume inside the car door, it includes steps A1 - A2:

[0057] Step A1, based on the performance parameters of the speaker, determine the one-way maximum stroke of the composite diaphragm of the speaker, and determine the equivalent diameter of the composite diaphragm;

[0058] As an example, as Figure 3 shown, it is a schematic diagram of the composite diaphragm, including the surround and the conical diaphragm. The equivalent diameter refers to the equivalent diameter D of the mouth of the composite diaphragm.

[0059] Step A2, based on the one-way maximum stroke and the equivalent diameter, determine the maximum change in the air volume inside the car door when the speaker is working.

[0060] As an example, based on the performance parameters of the speaker, such as the sound power Pa, the resonance frequency f0, the effective radiation diameter Deff of the composite diaphragm, according to determine the one-way maximum stroke of the composite diaphragm of the speaker. Among them, since the size of the composite diaphragm is not a strictly regular shape, the diameter of the composite diaphragm uses the equivalent diameter D.

[0061] As an example, the maximum change in the air volume inside the car door

[0062] Before step A2 of determining the maximum change in the air volume inside the car door when the speaker is working based on the one-way maximum stroke and the equivalent diameter, it includes:

[0063] Based on the electromagnetic module inside the speaker, determine the one-way maximum stroke of the composite diaphragm of the speaker.

[0064] As an example, the structure of the composite diaphragm of the speaker is not completely regular. When based on the equivalent diameter and the calculated one-way maximum stroke, the calculated maximum change in the air volume inside the car door may have a large deviation from the actual value. That is, the maximum change in the air volume inside the car door calculated based on the formula above is suitable when the composite diaphragm is relatively regular. When the shape of the composite diaphragm is irregular, if the theoretical calculation method is still used, the error will be large.

[0065] As an example, based on the electromagnetic module inside the speaker, the one-way maximum stroke of the composite diaphragm is determined. The electromagnetic module inside the speaker directly determines the vibration condition of the composite diaphragm. When the current in the electromagnetic module is larger, the magnetic field strength is stronger, the vibration condition of the composite diaphragm is stronger, and the one-way maximum stroke of the composite diaphragm is larger. In this embodiment, determining the one-way maximum stroke based on the electromagnetic module avoids the calculation error when the regularity of the composite diaphragm is not high, that is, it improves the problem that when the speaker works, it will cause the waterproof film to vibrate and deform, and the vibration and deformation of the waterproof film will bring noise to the speaker.

[0066] Step S12: Based on the maximum change amount of the air volume in the door cavity, determine the maximum pressure difference acting on the waterproof film when the speaker works.

[0067] As an example, according to the ideal gas state formula, it can be obtained that P0*(V0 + ΔV) = P*(V0 - ΔV), ΔP = P - P0. Wherein, P0 is the standard atmospheric pressure, V0 is the air volume in the door cavity when the speaker is not working, P is the pressure corresponding to the air in the door cavity when the speaker works (i.e., the pressure when the air volume in the door cavity is the smallest), and ΔP is the maximum pressure difference acting on the waterproof film when the speaker works.

[0068] As an example, based on the maximum change amount ΔV of the air volume in the door cavity, determine the maximum pressure difference ΔP acting on the waterproof film when the speaker works.

[0069] Step S20: Input the maximum pressure difference, the fixing method, the material parameters, and the initial structure into a preset simulation model, and determine the simulation deformation amount of the waterproof film;

[0070] As an example, the preset simulation model is a model for simulating and analyzing forces, and is used to analyze the deformation of an object according to the force condition.

[0071] As an example, the fixing method refers to the way the waterproof film is fixed on the inner wall of the door, which can be a pasting method, a screw fixing method, or a clamping fixing method.

[0072] In this embodiment, when the fixing method of the waterproof film is different, the vibration condition of the waterproof film after receiving an external force is different, and the tightness degrees under different fixing methods are inconsistent.

[0073] As an example, the material parameters refer to the parameters of the material of the waterproof film, including elastic modulus, Poisson's ratio, yield strength, and ultimate strength, etc.

[0074] As an example, the initial structure refers to the current structure of the waterproof film, such as the shape of the waterproof film, or whether there is a ribbed structure in the waterproof film, etc.

[0075] As an example, input the maximum pressure difference, the fixing method, the material parameters, and the initial structure into a preset simulation model, and determine the simulated deformation amount of the waterproof film.

[0076] After step S20, which is the step of inputting the maximum pressure difference, the fixing method, the material parameters, and the initial structure into a preset simulation model and determining the simulated deformation amount of the waterproof film, it includes:

[0077] If the simulated deformation amount is less than a preset critical value, evaluate that the waterproof film has normal deformation, and the evaluation ends.

[0078] As an example, if it is determined based on the simulation model that the simulated deformation amount of the waterproof film is less than a preset critical value, determine that the deformation of the waterproof film is normal, and end the evaluation of the deformation of the waterproof film.

[0079] Step S30, if the simulated deformation amount is greater than a preset critical value, optimize at least one of the initial structure, the fixing method, and the material parameters of the waterproof film.

[0080] As an example, if the simulated deformation amount is greater than a preset critical value, determine that the deformation of the waterproof film is abnormal, and the waterproof film needs to be optimized. The waterproof film itself has a direct impact on the deformation amount. Optimizing the waterproof film itself can reduce its deformation amount.

[0081] As an example, if the simulated deformation amount is greater than a preset critical value, optimize at least one of the initial structure, the fixing method, and the material parameters of the waterproof film.

[0082] Step S30, the step of optimizing at least one of the initial structure, the fixing method, and the material parameters of the waterproof film if the simulated deformation amount is greater than a preset critical value includes step S31:

[0083] Step S31, if the simulated deformation amount is greater than a preset critical value, optimize the waterproof film based on a preset optimization method until the simulated deformation amount is less than the critical value, where the optimization method includes at least one of adding ribs to the initial structure, replacing the material of the waterproof film, and replacing the fixing method.

[0084] As an example, if the deformation of the waterproof film is abnormal, it will generate noise and cause interference to the working speaker. The deformation amount can be reduced by adding ribs to the initial structure of the waterproof film to enhance the structural strength. Or the deformation amount can be reduced by changing the fixing method of the waterproof film to enhance its firmness. The deformation amount can also be reduced by optimizing the material parameters of the waterproof film to enhance the material performance.

[0085] As an example, optimize the waterproof film based on the optimization method until the simulated deformation amount is less than the critical value, where the optimization method includes at least one of adding ribs to the initial structure, replacing the material of the waterproof film, and replacing the fixing method.

[0086] Step S30, if the simulated deformation amount is greater than the preset critical value, after the step of optimizing at least one of the initial structure of the waterproof film, the fixing method, and the material parameters, it includes steps S41 - S43:

[0087] Step S41, store the simulated deformation amount, the optimized initial structure, and the optimized material parameters as an evaluation record locally;

[0088] As an example, after obtaining the simulated deformation amount based on the simulation model, store the simulated deformation amount, and store the optimized initial structure and the optimized material parameters as an evaluation record locally. Based on the stored local data, obtain a set of multiple local data, and use the set of multiple local data as a simulation record.

[0089] Step S42, generate the design parameters of the waterproof film based on the evaluation record;

[0090] Step S43, when receiving a design reference instruction, display the design parameters to the user.

[0091] As an example, generate design parameters corresponding to different initial structures and material parameters based on the simulation record.

[0092] As an example, the user can view the simulation record. When the user needs to view the simulation record, the evaluation device for the deformation of the waterproof film receives a design reference instruction. When receiving the design reference instruction, determine the waterproof film corresponding to the instruction. Based on the waterproof film, determine the corresponding design parameters and display the design parameters to the user.

[0093] In this embodiment, store the simulation result of each time of the simulation model as a simulation record, generate design parameters that can be referenced by different waterproof films according to the simulation record, which in turn promotes the improvement of the vibration situation of the waterproof film, enables the user to better obtain the waterproof film with optimized vibration situation, and the user has a higher evaluation efficiency for the deformation of the waterproof film with optimized vibration situation, that is, further avoids the problem of excessive vibration amplitude of the waterproof film during the operation of the speaker and generating noise.

[0094] The present application provides a method, device, equipment and storage medium for evaluating the deformation of a waterproof film. In the prior art, when a speaker operates, it causes the waterproof film to vibrate and deform, and the vibration and deformation of the waterproof film bring noise to the speaker. In the present application, the maximum pressure difference acting on the waterproof film when the speaker operates is determined, and the material parameters, fixing method and initial structure of the waterproof film are determined; the maximum pressure difference, the fixing method, the material parameters and the initial structure are input into a preset simulation model, and the simulated deformation amount of the waterproof film is determined; if the simulated deformation amount is greater than a preset critical value, at least one of the initial structure, the fixing method and the material parameters of the waterproof film is optimized. In the present application, based on the preset simulation model, the maximum pressure difference, etc. are processed to obtain the simulated deformation amount of the waterproof film. If it is determined that the simulated deformation amount does not meet the standard, the waterproof film is optimized to avoid the problem that the vibration amplitude of the waterproof film is too large when the speaker operates, resulting in noise.
