Specifically, the standard frequency response curve is: after the artificial mouth 11 outputs the standard sweep frequency sound source signal with stable voltage and continuously changing frequency, the artificial ear 13 receives the standard sweep frequency sound source signal, the artificial ear 13 and the processor 14 process the standard sweep frequency sound source signal received by the artificial ear 13, and the curve formed by the sound pressure (or level) of each frequency point is displayed through the display. The standard harmonic component curve is then: the standard swept source signal received by the artificial ear 13 is processed by the artificial ear 13 and the processor 14 to display a curve formed by the spectral harmonics on the display.
The processor 14 compares the frequency response curve to be tested and the harmonic component curve to be tested with the standard frequency response curve and the standard harmonic component curve of the first audio signal, respectively, and determines whether the earphone function of the electronic device 20 is abnormal.
In an embodiment, please refer to fig. 9, fig. 9 is a schematic flowchart illustrating the step S70 in fig. 4, and the step S70 further includes:
s71: and if the part of the curve to be tested is overlapped with the standard curve or is not overlapped at all, judging that the earphone function of the electronic equipment 20 is abnormal.
Specifically, if the curve to be tested is partially or completely not within the standard curve, that is, the curve to be tested and the standard curve are partially or completely not coincident, after the electronic device 20 is connected to the earphone 12, the first audio signal collected by the microphone 12 of the earphone 12 cannot be normally transmitted to the audio module of the electronic device 20, or the mode of the microphone 12 of the electronic device 20 is abnormal, so that the microphone 12 cannot normally collect the first audio signal, the processor 14 may determine that the earphone function of the electronic device 20 is abnormal.
If the curve to be tested is within the standard curve, that is, the curve to be tested completely coincides with the standard curve, the processor 14 may determine that the earphone function of the electronic device 20 is normal.
