It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0038] Unless otherwise specified, the term "plurality" means two or more.

[0039] In the embodiments of the present disclosure, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B.

[0040] The term "and / or" is a description of the association relationship of an object and indicates that three relationships can exist. For example, A and / or B means: A or B, or, A and B these three relationships.

[0041] The term "corresponding" can refer to an association relationship or a binding relationship. A corresponding to B means that there is an association relationship or a binding relationship between A and B.

[0042] The frequency response curve of an audio device can reflect the processing ability of the audio device for signals of different frequencies and is an important reference index for measuring the sound effect of the audio device.

[0043] The traditional process of frequency response testing for audio devices is as follows: First, the tester deploys the test environment and sets the parameters of each device according to the test requirements. For example, set the volume when the audio device plays sound. After that, a test signal is input into the audio device through a signal generator, and this test signal can be a swept-frequency signal. After the audio device processes the swept-frequency signal, it can play sound. The audio analyzer collects and analyzes the sound played by the audio device, and can generate the frequency response curve of the audio device. The tester manually adjusts the PEQ parameters of the audio device according to the frequency response curve of the audio device and the test requirements, and makes the audio device process the swept-frequency signal again for frequency response testing based on the adjusted PEQ parameters until the frequency response curve of the audio device meets the test requirements.

[0044] However, during the frequency response testing process of audio devices, it is usually necessary to adjust the PEQ parameters of the audio device multiple times. Using the method of manually adjusting the PEQ parameters of the audio device takes a relatively long time. Thus, it will affect the efficiency of the frequency response testing of audio devices. In addition, because the method of manually adjusting the PEQ parameters of the audio device is adopted, it is easy to have errors when adjusting the PEQ parameters, which will also affect the accuracy of the frequency response testing of audio devices.

[0045] In view of this, the embodiments of the present disclosure provide a method, device, equipment, and storage medium for frequency response testing, which can use the host computer to compare the frequency response curve of the audio device with the standard frequency response curve. The host computer can automatically adjust the PEQ parameters of the audio device according to the comparison result, without the tester manually adjusting the PEQ parameters, shortening the time-consuming for the audio device to perform frequency response testing. Thus, the efficiency of frequency response testing can be improved. In addition, the host computer automatically adjusts the PEQ parameters of the audio device. Compared with the method of manually adjusting the PEQ parameters, it can reduce the situation of errors occurring during the adjustment of the PEQ parameters, so as to improve the accuracy of the frequency response testing of the audio device.

[0046] Combined with Figure 1 As shown, the embodiments of the present disclosure provide a system applicable to the method of frequency response testing. The system includes a signal generator 11, an audio device 12, an audio analyzer 13, and a host computer 14. Among them:

[0047] In the embodiments of the present disclosure, the signal generator 11 can be an audio signal generator. For example, it can be an AP (AudioPrecision) audio signal generator. The signal generator 11 can be electrically connected to the audio device 12. The signal generator 11 can generate a swept-frequency signal according to the test requirements and input the swept-frequency signal into the audio device 12. The frequency range of this swept-frequency signal can be from 20 Hz to 20 kHz.

[0048] In the embodiments of the present disclosure, the audio device 12 may be an electronic device with an audio playback function. For example, it may be a television, a speaker, a computer, etc. The audio device 12 is electrically connected to the host computer 14. When the audio device 12 is a television, the swept-frequency signal generated by the signal generator 11 can be input into the television through the AV interface of the television. The audio device 12 can play sound by processing the swept-frequency signal.

[0049] In the embodiments of the present disclosure, the audio analyzer 13 is connected to the host computer 14. The audio analyzer 13 can collect the sound played by the audio device 12 and generate a frequency response curve based on the sound played by the audio device 12. The audio analyzer 13 can upload the generated frequency response curve of the audio device 12 to the host computer 14 so that the host computer 14 can display the frequency response curve of the audio device 12. The host computer 14 pre-stores a Figure 2 standard frequency response curve as shown. In the standard frequency response curve, the intensity difference between the sound intensity corresponding to the 400 Hz frequency point and the sound intensity corresponding to the 6.3 kHz frequency point is less than 30 dB. In the standard frequency response curve, the abscissa represents the frequency and the ordinate represents the sound intensity. Since the sound intensity is associated with the sound amplitude, the ordinate in the standard frequency response curve can also represent the sound amplitude. It should be noted that the above standard frequency response curve in the embodiments of the present disclosure is only exemplary, and the standard frequency response curve can correspond to the test requirements and is not specifically limited.

[0050] Combined with Figure 3 shown, the embodiments of the present disclosure provide a method for frequency response testing. This method can be applied to the host computer in the above embodiments. The method includes:

[0051] S31, comparing the frequency response curve generated by the audio analyzer with the standard frequency response curve and outputting the comparison result.

[0052] S32, judging whether the PEQ parameters of the audio device need to be adjusted according to the comparison result.

[0053] S33, when the PEQ parameters of the audio device need to be adjusted, adjusting the PEQ parameters of the audio device according to the comparison result and the test requirements.

[0054] S34, inputting the adjusted PEQ parameters into the audio device so that the audio device can perform frequency response testing based on the adjusted PEQ parameters.

[0055] Using the method for frequency response testing provided by the embodiments of the present disclosure, the host computer can compare the frequency response curve generated by the audio analyzer (i.e., the frequency response curve of the audio device) with the standard frequency response curve. Through the comparison, it can be determined whether the waveform of the frequency response curve is consistent with the waveform of the standard frequency response curve. If not, it indicates that the sound effect of the audio device is not good. Further, according to the comparison result of the frequency response curve and the standard frequency response curve, the PEQ parameters of the audio device need to be adjusted. Based on the adjusted audio parameters, the audio device can continue to perform frequency response testing. In this way, during the process of the audio device performing frequency response testing, the host computer can automatically adjust the PEQ parameters of the audio device without the tester manually adjusting the PEQ parameters, which shortens the time-consuming for the audio device to perform frequency response testing. Thus, the efficiency of frequency response testing can be improved. In addition, when the host computer automatically adjusts the PEQ parameters of the audio device, compared with the method of manually adjusting the PEQ parameters, the situation of errors occurring during the adjustment of the PEQ parameters can be reduced, so as to improve the accuracy of the frequency response testing of the audio device.

[0056] It should be noted that in the embodiments of the present disclosure, the PEQ parameters of the audio device at least include the frequency point F to be debugged, the gain Gain, and the influence range Q value. Among them, the larger the Q value, the smaller the frequency range affected during the adjustment process. On the contrary, the smaller the Q value, the larger the frequency range affected during the adjustment process.

[0057] Further, comparing the frequency response curve generated by the audio analyzer with the standard frequency response curve includes: comparing the signal intensity of the target frequency point in the frequency response curve with the signal intensity of the reference frequency point in the standard frequency response curve; wherein, the target frequency point is any frequency point in the frequency response curve, and the target frequency point has the same frequency as the reference frequency point.

[0058] In this embodiment, when the host computer compares the frequency response curve and the standard frequency response curve, it compares the signal intensities corresponding to the frequency points with the same frequency. The host computer can sequentially select the target frequency points and compare the signal intensities of each frequency point in the frequency response curve with the signal intensities of the corresponding frequency points in the standard frequency response curve. In this way, by comparing one by one according to the frequency points, it can accurately determine whether the signal intensity corresponding to each frequency point in the frequency response curve is standard, that is, accurately determine whether the signal intensity corresponding to each frequency point in the frequency response curve meets the test requirements. Compared with the scheme where the tester manually determines whether the frequency response curve meets the test requirements, the judgment accuracy can be improved, and thus the accuracy of subsequent adjustment of the PEQ parameters of the audio device can be improved. Thereby, the accuracy of the frequency response testing for the audio device is improved.

[0059] Further, after the host computer compares the frequency response curve generated by the audio analyzer with the standard frequency response curve, it can calculate the intensity difference between the signal intensity of the target frequency point in the frequency response curve and the signal intensity of the reference frequency point in the standard frequency response curve, and use this intensity difference as the comparison result.

[0060] In this embodiment, the host computer can output the signal strength of a certain frequency point in the frequency response curve, and compare it with the signal strength corresponding to the frequency point with the same frequency as this frequency point (i.e., the reference frequency point) in the standard frequency response curve. In this way, during the frequency response test of the audio device, based on the signal strength difference, it can be determined whether the frequency response curve of the audio device meets the test requirements. Specifically, it can be determined whether it is necessary to adjust the PEQ parameters of the audio device.

[0061] Furthermore, the solution for the host computer to determine whether the PEQ parameters of the audio device need to be adjusted according to the comparison result, that is, according to the above signal strength difference, includes: if the strength difference is within the error range, it is determined that the PEQ parameters of the audio device do not need to be adjusted. Or, if the strength difference is not within the error range, it is determined that the PEQ parameters of the audio device need to be adjusted.

[0062] During the frequency response test of the audio device, it is impossible to make the frequency response curve of the audio device exactly the same as the standard frequency response curve, and there will inevitably be some errors. In view of this, an error range is set in this embodiment. If it is determined that the signal strength difference is within the error range, it can be considered that the signal strength of the target frequency point in the frequency response curve meets the standard and meets the test requirements, and there is no need to adjust the PEQ parameters to continue the frequency response test of the audio device. In this way, when the frequency response curve of the audio device is basically close to the standard frequency response curve, the situation of frequently performing frequency response tests on the audio device can be reduced. Thus, the normal progress of the frequency response test process is ensured.

[0063] Furthermore, the host computer adjusts the PEQ parameters of the audio device according to the comparison result and the test requirements, including: calculating the gain value of the target frequency point according to the comparison result and the test requirements. Adjusting the PEQ parameters of the audio device according to the gain value of the target frequency point.

[0064] In this embodiment, when adjusting the PEQ parameters of the audio device, it is necessary to first calculate the gain value of the target frequency point, and then adjust according to the gain value of the target frequency point. Adjusting the PEQ parameters of the audio device is to make the audio device process the swept-frequency signal according to the adjusted PEQ parameters, and then make the sound played by the audio device change. In the frequency response curve generated after the changed sound is analyzed by the audio analyzer, the signal strength of the target frequency point is closer to the signal strength of the reference frequency point in the standard frequency response curve. That is, since the PEQ parameters of the audio device are adjusted according to the test requirements and the comparison result, then the test result obtained by the audio device based on the adjusted PEQ parameters is more in line with the test requirements. Compared with the scheme of manually adjusting the PEQ parameters, the number of times of adjusting the PEQ parameters can be reduced. Thus, the number of times of iterative frequency response tests of the audio device is reduced, which is beneficial to improving the efficiency of the frequency response test of the audio device.

[0065] Further, the host computer calculates the gain value of the target frequency point according to the comparison result and the test requirements, including: when there is a preset test condition corresponding to the target frequency point in the test requirements, calculating the gain value of the target frequency point according to the preset test condition and the intensity difference. Or, when there is no preset test condition corresponding to the target frequency point in the test requirements, calculating the gain value of the target frequency point according to the intensity difference of the target frequency point.

[0066] When performing a frequency response test on a target device, there may be test conditions defined by the tester in the test requirements. For example, for the frequency response curve of the target device, the signal intensities corresponding to some frequency points in the frequency response curve may not need to be adjusted. In this way, in this embodiment, when calculating the gain value of the target frequency point, it can be determined whether there is a preset test condition corresponding to the target frequency point in the test requirements, and the gain value of the target frequency point is calculated according to the preset test condition. Thus, during the frequency response test of the target device, the personalized test requirements of the tester can be met, and a customized frequency response test can be realized.

[0067] Optionally, in the embodiments of the present disclosure, when the PEQ parameters of the audio device do not need to be adjusted, it indicates that the signal intensities corresponding to each frequency point of the frequency response curve of the audio device are within the error range compared with the standard frequency response curve. In this way, the host computer can directly output a test report. In the embodiments of the present disclosure, when the PEQ parameters of the audio device need to be adjusted, the audio device can perform an iterative frequency response test based on the adjusted PEQ parameters until the signal intensities corresponding to each frequency point in the frequency response curve of the audio device are all within the error range, and then the host computer can output a test report.

[0068] Exemplarily, the test report may record the frequency response curve of the audio device and the test result of the audio device, so as to facilitate the tester to understand the process of the frequency response test of the audio device.

[0069] Optionally, in the embodiments of the present disclosure, the allowable error range of the test requirements may be 95% to 105% of the signal intensities corresponding to each frequency point in the standard frequency response curve.

[0070] Exemplarily, as shown in Figure 2 Assuming that the frequency of the reference frequency point is 5 kHz and the corresponding signal intensity is 66 dB, in the frequency response curve of the audio device, when the signal intensity corresponding to the target frequency point with a frequency of 5 kHz is within the range of 69.9 dB to 62.7 dB, it can be considered that the signal intensity of the target frequency point meets the test requirements.

[0071] As shown in Figure 4 The embodiments of the present disclosure provide a device for frequency response testing. This device can be integrated into the host computer in the above embodiments. The device includes: a comparison module 401, a judgment module 402, an adjustment module 403, and an input module 404. Among them:

[0075] An input module 404 is configured to input the adjusted PEQ parameters into the audio device so that the audio device performs a frequency response test based on the adjusted PEQ parameters.

[0076] Further, the comparison module 401 is specifically configured to: compare the signal strength of the target frequency point in the frequency response curve with the signal strength of the reference frequency point in the standard frequency response curve; wherein, the target frequency point is any frequency point in the frequency response curve, and the target frequency point has the same frequency as the reference frequency point.

[0077] Further, the comparison module 401 is specifically configured to: calculate the intensity difference between the signal strength of the target frequency point in the frequency response curve and the signal strength of the reference frequency point in the standard frequency response curve.

[0078] Further, the determination module 402 is specifically configured to: if the intensity difference is within the error range, determine that the PEQ parameters of the audio device do not need to be adjusted. Or, if the intensity difference is not within the error range, determine that the PEQ parameters of the audio device need to be adjusted.

[0079] Further, the adjustment module 403 is specifically configured to: calculate the gain value of the target frequency point according to the comparison result and the test requirements. Adjust the PEQ parameters of the audio device according to the gain value of the target frequency point.

[0080] Further, the adjustment module 403 is specifically configured to: calculate the gain value of the target frequency point according to the preset test condition and the intensity difference when there is a preset test condition corresponding to the target frequency point in the test requirements. Or, calculate the gain value of the target frequency point according to the intensity difference of the target frequency point when there is no preset test condition corresponding to the target frequency point in the test requirements.
