Specifically, the above-mentioned preset acoustic parameter values ​​may also include but are not limited to frequency response, sensitivity, total harmonic distortion + noise (THD+N) and sound insulation effects, etc., which are used to represent the sound display effect of the headphones. However, unlike the above-mentioned acoustic test parameters, the preset acoustic parameter values ​​can also be set to a range area value according to the needs of the headphones, that is, setting the frequency response range, sensitivity range, etc.

[0037] The above-mentioned abnormal values ​​of acoustic test parameters may refer to the acoustic parameter values ​​that deviate after comparing the actual performance data with the preset acoustic parameter values ​​during the production and acoustic testing process of the above-mentioned special-shaped exhaust port earphones. These deviated acoustic parameter values ​​may indicate that the special-shaped exhaust port earphones to be tested currently fail to meet the requirements in one or more acoustic performance indicators.

[0038] S403: Generate an acoustic test result report corresponding to the current special-shaped exhaust port earphone based on the abnormal value of the acoustic test parameter.

Based on a preset acoustic parameter value, determine a preset data curve corresponding to the parameter value and a characteristic value on the corresponding curve.

[0057] In an embodiment of the present invention, the above-mentioned preset data curve can be a coordinate curve diagram displayed on the analysis result of the audio analyzer according to the preset acoustic parameter value, that is, the audio data curve corresponding to the above-mentioned preset acoustic parameter, wherein the characteristic value in the audio data curve corresponding to the above-mentioned preset acoustic parameter is the above-mentioned preset acoustic parameter value.

[0058] S4032. Compare the characteristic values ​​on the curve corresponding to the audio data curve of the acoustic test parameter with the preset data curve and the characteristic values ​​on the corresponding curve, and determine the abnormal value of the acoustic test parameter within the preset adjustment range.

Specifically, the preset adjustment range can be based on the design requirements and usage scenarios of the headphones, and the test parameters that need to be strengthened for different design requirements and usage scenarios can be tested with a bias, so as to adjust the range of different parameters according to the results of the bias test.

[0060] Optional, such as Figure 8 As shown, step S404, based on the acoustic test result report corresponding to the current special-shaped exhaust port earphone, the step of judging the state of the current special-shaped exhaust port earphone also includes steps S408-S409, wherein: S408.

[0062] For example, when it is detected that the characteristic value of the high-frequency audio curve of the current headset does not overlap with the characteristic value of the preset high-frequency audio curve within a preset range, the corresponding high-frequency audio drive unit component can be detected to determine the component function defect data of the high-frequency audio drive unit component, that is, the cause of the defect of the current component, such as uneven materials in the production process, or environmental influences during the test process, which will affect the results of the acoustic test.
