[0001] The present invention relates to the field of data processing, and in particular to a method, a device and a storage medium for intelligently improving the sound quality of a Bluetooth speaker. Background Art

[0002] In the design of Bluetooth speakers, the bass reflex port is an important component for improving low-frequency response. By adjusting the position of the bass reflex port, the low-frequency output of the speaker can be enhanced, so that it can obtain a fuller bass effect under the condition of small volume. However, in actual design, the position of the bass reflex port and the simple arrangement of the cavity structure may cause the shell to vibrate, thus affecting the overall sound quality performance. In order to solve the distortion problem caused by the vibration of the shell, reinforcing ribs are usually set inside the speaker to increase the structural rigidity. However, the presence of reinforcing ribs may interfere with the airflow near the bass reflex port, affect the flow path and speed of the airflow, cause the bass reflex port to weaken the low-frequency enhancement effect, and even cause airflow noise problems.

[0003] The current technology of reinforcing rib design and bass reflex port position design is often relatively simple, and the mutual influence between the two is not fully considered. Especially in small Bluetooth speakers, the cavity space is limited, and the mutual interference between the reinforcing rib and the bass reflex port is more obvious. This design conflict makes it difficult to achieve the best low-frequency response and overall sound quality of the speaker. Summary of the invention

[0010] In a second aspect, the present invention provides a device for intelligently improving the sound quality of a Bluetooth speaker, the device comprising:

[0011] A scheme generating module, used for obtaining an inverted hole layout space and a reinforcing rib layout space for setting an inverted hole and a reinforcing rib in a Bluetooth speaker, generating a plurality of first speaker design schemes in the inverted hole layout space and the reinforcing rib layout space, and adjusting and obtaining a plurality of second speaker design schemes according to a preset speaker design scheme, wherein each speaker design scheme includes an inverted hole position distribution and a reinforcing rib position distribution;

[0012] A fitness analysis module, used to perform low-frequency response analysis, vibration analysis and inverted hole airflow disturbance analysis of the Bluetooth speaker according to the plurality of first speaker design schemes and the plurality of second speaker design schemes, and calculate and obtain a plurality of first sound quality fitnesses and a plurality of second sound quality fitnesses;

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0025] like Figure 1 As shown, an embodiment of the present invention provides a method for intelligently improving the sound quality of a Bluetooth speaker, comprising:

[0026] S10: Obtaining an inverted hole layout space and a reinforcing rib layout space for setting an inverted hole and a reinforcing rib in a Bluetooth speaker, generating a plurality of first speaker design schemes in the inverted hole layout space and the reinforcing rib layout space, and adjusting a plurality of second speaker design schemes according to a preset speaker design scheme, wherein each speaker design scheme includes an inverted hole position distribution and a reinforcing rib position distribution;

[0027] In the embodiment of the present application, in order to optimize the low-frequency response of the Bluetooth speaker and reduce the vibration of the housing, it is first necessary to obtain the layout space inside the speaker for the bass reflex hole and the reinforcement rib. Specifically, the bass reflex hole layout space refers to the position range inside the speaker where the bass reflex hole is allowed to be installed, and the reinforcement rib layout space refers to the position area inside the speaker where the reinforcement rib can be installed.

[0028] After obtaining the bass reflex hole layout space and the reinforcement rib layout space, multiple initial first speaker design schemes can be generated based on the bass reflex hole layout space and the reinforcement rib layout space. Each first speaker design scheme includes the position distribution of the bass reflex hole and the position distribution of the reinforcement rib. The bass reflex hole position distribution refers to the position selection of the bass reflex hole in the speaker cavity, while the reinforcement rib position distribution refers to the position selection of the reinforcement rib in the cavity. Different bass reflex hole and reinforcement rib distribution schemes will have different effects on the low-frequency response, vibration characteristics, and airflow characteristics of the speaker.

[0029] After generating a plurality of first speaker design schemes, the plurality of first speaker design schemes are adjusted according to a preset speaker design scheme to generate a plurality of second speaker design schemes. The preset speaker design scheme includes a preset bass reflex hole position distribution and a reinforcement rib position distribution, such as an unoptimized bass reflex hole position distribution and reinforcement rib position distribution in a current Bluetooth speaker, which is preliminarily considered to be a relatively excellent speaker design scheme, and the plurality of first speaker design schemes are adjusted based on the preset speaker design scheme.

[0030] Step S10 in the method provided in the embodiment of the present application includes:

[0031] In the embodiment of the present application, in the design process of the Bluetooth speaker, in order to optimize the low-frequency response of the speaker and reduce the vibration of the shell, it is first necessary to determine the layout space of the bass reflex hole and the reinforcing rib. The bass reflex hole layout space refers to the position range inside the speaker suitable for installing the bass reflex hole, which affects the low-frequency response effect of the speaker; and the reinforcing rib layout space refers to the position area inside the speaker suitable for installing the reinforcing rib, which is mainly used to enhance the structural rigidity of the speaker and reduce the vibration of the shell.

[0032] Multiple initial design schemes are randomly generated in the bass reflex hole layout space and the reinforcement rib layout space, namely, multiple first bass reflex hole position distributions and multiple first reinforcement rib position distributions. Each bass reflex hole position distribution includes the position information of the bass reflex holes of a preset number of bass reflex holes, which determines the specific position and layout of the bass reflex holes; each reinforcement rib position distribution also includes the reinforcement rib position information of a preset number of reinforcement ribs, which is used to define the arrangement and layout of the reinforcement ribs. Through these distribution combinations, multiple first speaker design schemes are formed, each of which is a possible configuration of the bass reflex hole and reinforcement rib layout. The preset number of bass reflex holes and the preset number of reinforcement ribs are set according to the design scheme of the Bluetooth speaker, and can be the same or different.

[0033] Furthermore, a preset speaker design scheme is obtained, which includes a predefined distribution of bass reflex holes and a predefined distribution of reinforcing ribs as a basis for design adjustment. The preset speaker design scheme is usually based on experience or preliminary design results, and is intended to provide a reference for the subsequent optimization process. Exemplarily, the bass reflex hole distribution and the reinforcing rib distribution that are optimized for the current Bluetooth speaker are used as the preset speaker design scheme.

[0034] According to the preset inverted hole position distribution and the preset reinforcing rib position distribution, the adjustment step length is used to adjust the positions of the multiple first inverted hole position distributions and the multiple first reinforcing rib position distributions, so as to obtain multiple second inverted hole position distributions and multiple second reinforcing rib position distributions, and obtain multiple second sound box design solutions. The adjustment step length refers to the distance moved during each position adjustment, for example, 5mm. Specifically, according to the preset inverted hole position information of the preset number of inverted holes in the preset inverted hole position distribution and the preset reinforcing rib position distribution, the first inverted hole position information of the preset number of inverted holes in the first inverted hole position distribution is adjusted, wherein the inverted holes of the preset number of inverted holes can be numbered, and then according to the corresponding relationship between the numbers, the first inverted hole position information in the first inverted hole position distribution is adjusted to the preset inverted hole position information by the distance of the adjustment step length, so as to obtain the adjusted second inverted hole position information, and thus, multiple second inverted hole position distributions are obtained.

[0035] Based on the same method, the reinforcement ribs with a preset number of reinforcement ribs can be numbered, and then the first reinforcement rib position information of the reinforcement ribs with the same number in the first reinforcement rib position distribution can be adjusted to the preset reinforcement rib position information in the preset reinforcement rib position distribution to obtain multiple second reinforcement rib position distributions.

[0036] By combining the position distribution of the plurality of second inverted holes and the position distribution of the plurality of second reinforcing ribs, a plurality of second sound box design solutions are obtained.

[0037] In the embodiment of the present application, the preset speaker design scheme is a relatively excellent speaker design scheme based on experience-based design. Taking it as the basis for adjusting the multiple randomly generated first speaker design schemes can improve the globality and accuracy of the optimization of the bass reflex holes and reinforcement rib positions, and lay the foundation for subsequent accurate optimization.

[0038] S20: performing a low-frequency response analysis, a vibration analysis, and an inverted hole airflow disturbance analysis of the Bluetooth speaker according to the plurality of first speaker design schemes and the plurality of second speaker design schemes, and calculating and obtaining a plurality of first sound quality fitness degrees and a plurality of second sound quality fitness degrees;

[0039] In the embodiment of the present application, after obtaining multiple first speaker design solutions and multiple second speaker design solutions, the multiple first speaker design solutions and multiple second speaker design solutions are analyzed to evaluate their performance in different acoustic and structural performances. Specifically, it is necessary to perform low-frequency response analysis, vibration analysis, and inverted hole airflow disturbance analysis on each speaker design solution to fully understand the advantages and disadvantages of each speaker design solution.

[0040] The purpose of low-frequency response analysis is to evaluate the sound performance of the speaker in the low-frequency band to analyze the degree to which the distribution of the bass reflex port position enhances the low-frequency output. Vibration analysis focuses on the structural stability of the speaker. By analyzing the vibration characteristics of the speaker shell, it can be determined whether the arrangement of the reinforcement ribs effectively reduces the resonance and unnecessary vibration of the shell. The analysis of airflow disturbance of the bass reflex port aims to evaluate the effect of the reinforcement rib layout on the airflow near the bass reflex port. The design of the bass reflex port directly affects the low-frequency response of the speaker, and the location of the reinforcement ribs may interfere with the airflow of the bass reflex port, resulting in unstable airflow or noise.

[0041] After completing the above three analyses, the sound quality fitness of each speaker design solution is calculated according to the analysis results, and a plurality of first sound quality fitnesses and a plurality of second sound quality fitnesses are obtained.

[0042] Through the above sound quality fitness evaluation calculation, we can intuitively compare the advantages and disadvantages of different design solutions, identify the best solution in low-frequency response, vibration control and airflow management, and provide data support and decision-making basis for further design optimization. Ultimately, these analyses and fitness calculations lay a solid foundation for improving the sound quality of Bluetooth speakers and ensure the sound quality performance of the designed speakers.

[0043] Step S20 in the method provided in the embodiment of the present application includes:

[0044] Collect a sample inverted hole position distribution set and a sample reinforcement rib position distribution set, and annotate a sample low-frequency response distortion rate set, a sample speaker vibration amplitude set, and a sample inverted hole airflow velocity disturbance change rate set according to the low-frequency response distortion rate, the speaker vibration amplitude, and the inverted hole airflow velocity disturbance change rate under different sample inverted hole position distributions and sample reinforcement rib position distributions;

[0045] The sample inverted hole position distribution set and the sample reinforcing rib position distribution set are used as supervised training inputs, and the sample low-frequency response distortion rate set, the sample sound box vibration amplitude set and the sample inverted hole airflow velocity disturbance change rate set are used as supervised training outputs to train a sound quality analyzer;

[0046] Using the sound quality analyzer, input analysis is performed on the distribution of inverted holes and reinforcing ribs in the first speaker design and a plurality of second speaker design schemes to obtain a plurality of first analysis result sets and a plurality of second analysis result sets;

[0047] A plurality of first sound quality fitness measures and a plurality of second sound quality fitness measures are calculated based on the plurality of first analysis result sets and the plurality of second analysis result sets.

[0048] In the embodiment of the present application, based on the design test data of the same model of Bluetooth speakers for adjusting the design of the inverted holes and reinforcing ribs, a large amount of sample data is collected to construct a sample inverted hole position distribution set and a sample reinforcing rib position distribution set. The sample inverted hole position distribution set and the sample reinforcing rib position distribution set contain the position distribution information of the inverted holes and reinforcing ribs in different speaker design schemes in the previous Bluetooth speaker design process.

[0049] Furthermore, detailed physical and acoustic measurements are performed based on the speaker performance under these different sample inverted hole position distribution combinations and sample reinforcement rib position distribution combinations in the design test data. Specifically, the low-frequency response distortion rate, speaker vibration amplitude, and inverted hole airflow velocity disturbance change rate in each sample design are measured and recorded. The low-frequency response distortion rate indicates the degree of distortion of the speaker in the low-frequency band and is a key indicator for measuring bass quality; the speaker vibration amplitude reflects the vibration intensity of the speaker shell at different frequencies. The larger the vibration amplitude, the greater the negative impact on the sound quality; the inverted hole airflow velocity disturbance change rate indicates the instability of the airflow near the inverted hole. If the airflow disturbance is large, it may cause airflow noise and affect the low-frequency response. These measurement data are respectively labeled as the sample low-frequency response distortion rate set, the sample speaker vibration amplitude set, and the sample inverted hole airflow velocity disturbance change rate set.

[0050] Among them, a high-precision microphone, an audio interface and a spectrum analyzer can be used to collect the output signal of the Bluetooth speaker in the low frequency band under different sample inverted hole position distributions and sample reinforcement rib position distributions, separate the fundamental frequency and its harmonic components, calculate the amplitude of each order of harmonics, and use the sum of their ratios to the fundamental amplitude to represent the total harmonic distortion (THD). The speaker vibration amplitude refers to the vibration amount of the speaker shell or panel at different frequencies, which can be obtained through vibration meter testing. In addition, a hot wire anemometer can be used to record the speed and fluctuation of the airflow in the inverted hole when a low-frequency test signal is played in the inverted hole or near the outlet, obtain the rate of change of the airflow velocity and the airflow velocity without the influence of the reinforcement rib, and obtain the disturbance change rate of the airflow velocity in the sample inverted hole.

[0051] Furthermore, the sample inverted hole position distribution set and the sample rib position distribution set are used as supervised training inputs, and the sample low-frequency response distortion rate set, the sample speaker vibration amplitude set, and the sample inverted hole airflow velocity disturbance change rate set are used as supervised training outputs to train a sound quality analyzer. The sound quality analyzer is a data-driven model that can predict the low-frequency distortion, vibration amplitude, and airflow disturbance of the speaker based on the input inverted hole and rib position distribution.

[0052] Among them, exemplarily, a BP neural network is selected as the network structure of the sound quality analyzer, and the sound quality analyzer is constructed. The sample inverted hole position distribution set and the sample reinforcement rib position distribution set are used as the input features of the model, and the sample low-frequency response distortion rate set, the sample sound box vibration amplitude set and the sample inverted hole airflow velocity disturbance change rate set are used as the output labels of the model. The sound quality analyzer is trained using the training set data, and the internal parameters are adjusted by minimizing the error between the predicted value and the actual value. According to the output of the sound quality analyzer and the error of the sample low-frequency response distortion rate, the sample sound box vibration amplitude, and the sample inverted hole airflow velocity disturbance change rate, the parameters of the sound quality analyzer are adjusted, such as the number of layers and the number of nodes, until the error meets the requirements, for example, less than 5%. The sound quality analyzer can be further verified, and the training is completed after the verification is qualified.

[0053] After the sound quality analyzer is trained, the distribution of the positions of the inverted holes and the positions of the reinforcing ribs in the first speaker design and the plurality of second speaker design schemes are input into the sound quality analyzer for analysis. The sound quality analyzer performs predictive analysis on these design schemes based on the trained model, and outputs a plurality of first analysis result sets and a plurality of second analysis result sets, which respectively contain the performance data of the respective schemes in terms of low-frequency distortion, vibration control and airflow disturbance, namely, the low-frequency response distortion rate, the vibration amplitude of the speaker and the change rate of the airflow velocity disturbance of the inverted hole.

[0054] Finally, based on these analysis results, the sound quality fitness of each design solution is calculated. By comparing the sound quality fitness of multiple first speaker design solutions and second speaker design solutions, it is determined which solutions perform best in terms of sound quality improvement, providing reliable data support for subsequent design optimization and actual manufacturing. In this way, it can be ensured that the layout of the inverted holes and reinforcement ribs minimizes low-frequency distortion, vibration, and airflow noise while maximizing the sound quality performance of the speaker.

[0055] In the embodiment of the present application, the step of "calculating and obtaining a plurality of first sound quality fitness measures and a plurality of second sound quality fitness measures according to the plurality of first analysis result sets and the plurality of second analysis result sets" includes:

[0056] Construct the sound quality improvement function as follows: ;

[0057] Among them, SQL is the sound quality adaptability, , and is the weight, To analyze the obtained low frequency response distortion rate, To preset the low frequency response distortion rate, To preset the vibration amplitude of the speaker, To analyze the obtained speaker vibration amplitude, m is the number of preset inverted holes, The change rate of the airflow velocity disturbance of the i-th inverted hole is obtained by analysis;

[0058] According to the sound quality improvement function, a plurality of first sound quality fitnesses and a plurality of second sound quality fitnesses of a plurality of first analysis result sets and a plurality of second analysis result sets are obtained by calculation.

[0059] In the embodiment of the present application, in order to improve the sound quality of the Bluetooth speaker and minimize low-frequency distortion, vibration and airflow noise, a sound quality improvement function is constructed as follows: ;

[0060] Among them, SQL is the sound quality adaptability, , and is the weight, , and The sum of is 1, for example, they are 0.4, 0.3 and 0.3 respectively, is the low frequency response distortion rate obtained in the current analysis, It is a preset low-frequency response distortion rate, for example, the low-frequency response distortion rate of a Bluetooth speaker under a preset speaker design scheme. The lower the low-frequency response distortion rate, the better the sound quality, and the higher the sound quality adaptability should be. It is the preset speaker vibration amplitude, for example, the speaker vibration amplitude of the Bluetooth speaker under the preset speaker design scheme. A design scheme with a smaller vibration amplitude can usually reduce the sound quality degradation caused by structural resonance, so the sound quality adaptability is inversely proportional to the vibration amplitude. is the vibration amplitude of the speaker obtained by the current analysis, m is the number of preset inverted holes, is the change rate of the airflow velocity disturbance of the i-th inverted hole obtained in the current analysis. The smaller the airflow velocity disturbance, the smoother the low-frequency performance, so the sound quality adaptability is also inversely proportional to the change rate of the airflow disturbance.

[0061] According to the above sound quality improvement function, firstly, based on the above steps, the distribution of each inverted hole position and the distribution of the reinforcing rib position in the multiple first speaker design schemes and the second speaker design schemes are analyzed in detail to obtain the respective low-frequency response distortion rate, speaker vibration amplitude and inverted hole airflow velocity disturbance change rate data. Substitute these data into the sound quality improvement function to calculate the first sound quality fitness and the second sound quality fitness of each design scheme respectively.

[0062] The above steps provide a quantitative evaluation standard for evaluating the design of the bass reflex port and the reinforcement rib. The sound quality performance of each design scheme can be quantified by calculating the sound quality fitness, and the design schemes can be sorted and optimized according to the fitness level. The scheme with higher sound quality fitness indicates that the scheme has better comprehensive performance in low-frequency response, vibration control and airflow management, which helps to select or further improve the final design of the Bluetooth speaker.

[0063] S30: configuring multiple cross-update probabilities of the multiple first sound box design schemes and the multiple second sound box design schemes according to the multiple first sound quality fitness degrees and the multiple second sound quality fitness degrees, configuring the reinforcing rib update probability according to the result of the airflow disturbance analysis of the inverted hole, and performing random selection and cross-update on the multiple first sound box design schemes and the multiple second sound box design schemes to obtain multiple third sound box design schemes;

[0064] In an embodiment of the present application, in order to improve the sound quality improvement effect of optimizing the position of the bass reflex hole and the reinforcement ribs in the Bluetooth speaker and improve the randomness and globality of the optimization, multiple first speaker design schemes and multiple second speaker design schemes are randomly selected, and the positions of the reinforcement ribs in the speaker design schemes are randomly cross-updated.

[0065] Among them, the cross-update probability of each design scheme is configured according to the sound quality fitness (SQL) of each design scheme. The higher the sound quality fitness, the better the speaker design scheme performs in various key sound quality indicators. Therefore, the speaker design scheme with higher sound quality fitness should be given a higher cross-update probability, thereby increasing the probability of obtaining a better speaker design scheme through overall optimization.

[0066] And, according to the change rates of the airflow velocity disturbance of the m inverted holes in the multiple first speaker design schemes and the multiple second speaker design schemes obtained by the airflow disturbance analysis of the inverted holes in the above content, that is, the analysis results of the airflow disturbance of the inverted holes, the cross-update probability of the position information of multiple reinforcing ribs in each speaker design scheme is configured. Among them, the reinforcing ribs near the inverted holes will affect the airflow of the inverted holes, thereby affecting the low-frequency response and sound quality. Therefore, according to the analysis results of the airflow disturbance of the inverted holes, the cross-update probability of the position information of multiple reinforcing ribs in each speaker design scheme is configured, for example, the reinforcing rib update probability of the reinforcing ribs closest to each inverted hole is configured.

[0067] Furthermore, the first speaker design and the second speaker design are randomly selected and combined according to the configured cross-update probability and the rib update probability. Random selection cross-update refers to randomly selecting a random number of first and second speaker design from the existing multiple first speaker design and multiple second speaker design, exchanging the rib position information randomly selected according to the rib update probability in the selected first and second speaker design to generate a new design. In this process, designs with higher sound quality adaptability are more likely to be selected in the new combination due to their higher cross-update probability, which helps to gradually improve the overall sound quality performance of the design, and the rib position information with a higher rib update probability has a greater probability of being selected, and the position information is exchanged. In this way, multiple third speaker designs are obtained.

[0068] Through the above random selection and cross-update, multiple third speaker design solutions are generated. This process makes it possible for the new solution generated in each iteration to be better than the previous solution in terms of sound quality, thus gradually approaching the optimal speaker design and improving the randomness and globality of the optimization.

[0069] Step S30 in the method provided in the embodiment of the present application includes:

[0070] According to the plurality of first sound quality fitness measures and the plurality of second sound quality fitness measures, a plurality of first scheme cross-update probabilities and a plurality of second scheme cross-update probabilities are calculated and allocated;

[0071] According to the results of the airflow disturbance analysis of the inverted hole, the probability of updating the reinforcing ribs is configured to obtain a plurality of first reinforcing rib position intersection probability sets and a plurality of second reinforcing rib position intersection probability sets of a plurality of first sound box design schemes and a plurality of second sound box design schemes;

[0072] According to the multiple first scheme cross-update probabilities and the multiple second scheme cross-update probabilities, randomly selecting a cross-number of cross-first speaker design schemes and a cross-second speaker design scheme from the multiple first speaker design schemes and the multiple second speaker design schemes;

[0073] According to the multiple first reinforcement rib position intersection probability sets and the multiple second reinforcement rib position intersection probability sets, within the crossed first speaker design schemes and crossed second speaker design schemes with the crossed numbers, the reinforcement rib position information of the crossed numbers of reinforcement ribs is randomly selected for cross-update to obtain multiple third speaker design schemes.

[0074] In the embodiment of the present application, first, according to the plurality of first sound quality fitnesses and the plurality of second sound quality fitnesses, a plurality of first scheme cross-update probabilities and second scheme cross-update probabilities are calculated and allocated. Exemplarily, the ratio of each first sound quality fitness to the sum of the plurality of first sound quality fitnesses is calculated as the first scheme cross-update probability, and the ratio of each second sound quality fitness to the sum of the plurality of second sound quality fitnesses is calculated as the second scheme cross-update probability.

[0075] Furthermore, according to the results of the airflow disturbance analysis of the inverted holes, the probability of updating the reinforcing ribs is configured to obtain a plurality of first reinforcing rib position intersection probability sets and a plurality of second reinforcing rib position intersection probability sets of the plurality of first speaker design schemes and the plurality of second speaker design schemes.

[0076] The step of "randomly selecting a crossover number of first speaker design schemes and a crossover second speaker design scheme from among the plurality of first speaker design schemes and the plurality of second speaker design schemes according to the crossover update probabilities of the plurality of first schemes and the crossover update probabilities of the plurality of second schemes" in the method provided in the embodiment of the present application includes:

[0077] According to the airflow disturbance analysis results of the bass reflex holes of the multiple first speaker design schemes and the multiple second speaker design schemes, multiple first reinforcement rib position crossover probability sets and multiple second reinforcement rib position crossover probability sets are calculated for the position information of multiple reinforcement ribs closest to the multiple bass reflex holes respectively.

[0078] In the embodiment of the present application, according to the change rates of the airflow velocity disturbance of the m inverted holes in the multiple first speaker design schemes and the multiple second speaker design schemes obtained by the above content analysis, the position information of the multiple reinforcing ribs closest to the m inverted holes is respectively allocated to calculate the reinforcing rib position intersection probability. Exemplarily, the airflow disturbance analysis results of the inverted holes of each first speaker design scheme or the second speaker design scheme include the change rates of the airflow velocity disturbance of the m inverted holes, and the ratio of the change rate of the airflow velocity disturbance of each inverted hole to the sum of the change rates of the airflow velocity disturbance of the m inverted holes is calculated as the reinforcing rib position intersection probability of the reinforcing rib position information with the smallest distance from the position information of the inverted hole. In this way, the first reinforcing rib position intersection probability set and the multiple second reinforcing rib position intersection probability sets can be calculated. Among them, based on the calculation of the distance between the inverted hole position information and the multiple reinforcing rib position information in each speaker design scheme, the reinforcing rib corresponding to the reinforcing rib position information with the smallest distance can be used as the reinforcing rib closest to the inverted hole.

[0079] Based on the calculated cross-update probabilities of the multiple first solutions and the cross-update probabilities of the multiple second solutions, a cross-number of design solutions are randomly selected from the multiple first speaker design solutions and the second speaker design solutions to generate a cross-first speaker design solution and a cross-second speaker design solution. The cross-number can be set in advance, for example, to 30% of the number of the multiple first speaker design solutions. Among them, the speaker design solution with a large cross-update probability has a high probability of being selected, and can be randomly selected from the multiple first speaker design solutions and the second speaker design solutions based on the existing random selection algorithm.

[0080] Further, according to the multiple first reinforcement rib position cross probability sets and the multiple second reinforcement rib position cross probability sets, within the cross first speaker design scheme and the cross second speaker design scheme with the cross number, the reinforcement rib position information of the cross number of reinforcement ribs is randomly selected for cross update. Exemplarily, within the selected cross first speaker design scheme and the cross second speaker design scheme with the cross number, according to the reinforcement rib position distribution within the cross first speaker design scheme and the cross second speaker design scheme, according to the multiple first reinforcement rib position cross probability sets and the multiple second reinforcement rib position cross probability sets, the first reinforcement rib position information of the cross number of reinforcement ribs and the first reinforcement rib position information are randomly selected in the cross first speaker design scheme and the cross second speaker design scheme for exchange, and the cross update is completed, and the position information of other unselected reinforcement ribs and bass reflex holes is not adjusted, and multiple third speaker design schemes are obtained.

[0081] Exemplarily, the number of reinforcing rib crossovers can be preset, for example, 30% of the number of reinforcing ribs in each speaker design, and when the reinforcing rib position information is randomly selected for the crossover first speaker design and the crossover second speaker design, a crossover first speaker design and a crossover second speaker design are randomly selected for crossover update until the crossover first speaker design and the crossover second speaker design form a crossover speaker design combination with half the number of crossovers, and a group of two reinforcing rib position information randomly selected in the crossover first speaker design and the crossover second speaker design is randomly selected and crossover update is completed. The greater the probability of reinforcing rib position crossover, the greater the probability of being selected for crossover update.

[0082] S40: Continue to perform low-frequency response analysis, vibration analysis and inverted hole airflow disturbance analysis of the Bluetooth speaker according to the multiple third speaker design schemes, calculate and obtain multiple third sound quality adaptability, judge and update the preset speaker design scheme, and continue to perform iterative optimization to obtain the optimal speaker design scheme, and design and manufacture the Bluetooth speaker to improve the sound quality.

[0083] In the embodiment of the present application, after obtaining multiple third speaker design solutions, these solutions need to be further analyzed and evaluated.

[0084] Exemplarily, based on the same method as the above, multiple third speaker design schemes are subjected to low-frequency response analysis, vibration analysis and inverted hole airflow disturbance analysis of Bluetooth speakers, and multiple third sound quality fitnesses are obtained through sound quality improvement function calculation. Next, the above-mentioned multiple first sound quality fitnesses, multiple second sound quality fitnesses and third sound quality fitnesses are compared with the preset speaker design scheme, and the preset speaker design scheme is discriminated and updated by means of discriminant update to gradually update the optimization results and the basis for optimization adjustment, and iterative optimization is continued until convergence to obtain the optimal speaker design scheme, and the Bluetooth speaker is designed and manufactured to improve the sound quality. By improving the inverted hole and reinforcing rib layout, the bass performance of the speaker is improved, vibration interference is reduced, and the smooth flow of airflow is ensured, thereby achieving a higher level of sound quality and a better user listening experience.

[0085] Step S40 in the method provided in the embodiment of the present application includes:

[0086] Continue to perform low-frequency response analysis, vibration analysis and inverted hole airflow disturbance analysis of the Bluetooth speaker according to the plurality of third speaker design schemes, and calculate and obtain a plurality of third sound quality adaptability;

[0087] Obtaining a preset sound quality fitness of the preset speaker design scheme, combining the plurality of first sound quality fitnesses, the plurality of second sound quality fitnesses, and the plurality of third sound quality fitnesses, performing a determination update, and updating the speaker design scheme with the greatest sound quality fitness as the preset speaker design scheme;

[0088] Continue to randomly generate speaker design solutions in the inverted hole layout space and the reinforcing rib layout space, and continue to perform iterative optimization to obtain the optimal speaker design solution.

[0089] In an embodiment of the present application, based on step S20 in the aforementioned content, low-frequency response analysis, vibration analysis and inverted hole airflow disturbance analysis of the Bluetooth speaker are performed on multiple third speaker design schemes, and multiple third sound quality adaptability is calculated through a sound quality improvement function.

[0090] The preset sound quality adaptability of the preset speaker design scheme is obtained. The preset sound quality adaptability of the preset speaker design scheme can be based on the same method as the aforementioned content, and the Bluetooth speaker under the preset speaker design scheme is subjected to a low-frequency response test, a vibration test, and an inverted hole airflow disturbance test to calculate the preset sound quality adaptability.

[0091] Combine multiple first sound quality fitnesses, multiple second sound quality fitnesses, and multiple third sound quality fitnesses to perform a judgment update, wherein it is judged whether any of the multiple first sound quality fitnesses, multiple second sound quality fitnesses, and multiple third sound quality fitnesses is greater than the preset sound quality fitness. If so, the speaker design scheme with the largest maximum sound quality fitness is updated to the preset speaker design scheme. If not, the preset speaker design scheme is not updated. By judging and updating the preset speaker design scheme, the results of the optimization stage can be gradually improved, and the fitness of the subsequent adjustment of the speaker design scheme can be improved, thereby improving the accuracy and overallness of the optimization.

[0092] Furthermore, continue to randomly generate speaker design solutions in the space where the inverted holes are arranged and the space where the reinforcing ribs are arranged, for example, randomly generate multiple fourth speaker design solutions, adjust them according to the updated preset speaker design solutions to obtain multiple fifth speaker design solutions, then cross-update the multiple fourth speaker design solutions and the multiple fifth speaker design solutions to obtain multiple sixth speaker design solutions, and then discriminate and update the preset speaker design solutions again. In this way, perform iterative optimization until convergence, for example, reaching a preset number of optimization times, or the preset speaker design solution is not updated in five discriminated updates, then convergence, output the speaker design solution with the maximum final sound quality adaptability, and obtain the optimal speaker design solution.

[0093] The embodiments of the present application achieve the following technical effects through the above specific implementation methods:

[0094] The present invention effectively solves the conflict between the layout of the inverted holes and the layout of the reinforcing ribs in the Bluetooth speaker by generating and iteratively optimizing multiple speaker design schemes, and significantly improves the overall sound quality performance of the speaker. Specifically, by obtaining the layout space of the inverted holes and the layout space of the reinforcing ribs, and generating multiple initial speaker design schemes on this basis, and then combining the low-frequency response analysis, vibration analysis and inverted hole airflow disturbance analysis, the sound quality adaptability of each design scheme is accurately evaluated to ensure that the scheme selection and update in the optimization process have a scientific basis. The scheme uses multiple iterative optimizations to fully consider the interaction between the position of the inverted holes, the position of the reinforcing ribs, the low-frequency response and the airflow disturbance. The design scheme is cross-updated by calculating the sound quality adaptability, so that the design scheme generated after each iteration is more targeted and optimized. The optimized layout of the inverted holes significantly improves the low-frequency response of the Bluetooth speaker and enhances the bass performance; the reasonable configuration of the reinforcing ribs effectively reduces the vibration of the cavity, reduces distortion, and further improves the clarity and accuracy of the sound. In addition, the precise analysis of the airflow disturbance of the inverted hole is combined with the optimization and adjustment of the reinforcement ribs to ensure the smooth flow of airflow, avoid the degradation of sound quality caused by airflow noise, and achieve the technical effect of improving the sound quality of the Bluetooth speaker. Finally, through multiple iterations and optimizations, an optimal speaker design was obtained. In actual manufacturing, it can significantly improve the low-frequency performance of the Bluetooth speaker, reduce the impact of vibration and eliminate airflow noise, which improves the overall sound quality of the speaker and provides a better user listening experience.
