Specifically, since the detection data is recorded and compressed when abnormal sound occurs, the detection data is erroneous data.

Therefore, if in step S51, the detection data is consistent with the sound source data, it proves that the sound source data is wrong or the path of the sound source data from the memory 10 to the digital signal processor 20 is faulty. At this time, it is possible to confirm whether the audio source data is wrong by connecting the audio source to other playback devices for playback. If abnormal sound also occurs during playback on other playback devices, it means that the audio source data is wrong; otherwise, it means that there is a problem with the path from the memory 10 to the digital signal processor 20 . The other playback setting may be a computer, mainly considering that the sound effect of the computer is better, and it is more general, easy to obtain, and low cost.

Therefore, sub-step S52 may include the following sub-steps:

If in step S53, the detection data is consistent with the playback data, it means that the sound source data, or the path of the sound source data from the memory 10 to the digital signal processor 20, or the digital signal There is a problem with the processor 20. In the case where the audio source data has been excluded or the path from the memory 10 to the digital signal processor 20 has a problem, it can be determined that the digital signal processor 20 has a problem.

On the contrary, if in step S53, the detection data is inconsistent with the playback data, it means that the problem is not in the audio source data, or the path from the memory 10 to the digital signal processor 20, or the digital signal processing The device 20 needs to make further judgment, so it goes to step S55.

If in step S55, the detection signal is consistent with the playback signal, it means that the audio source data, or the path of the audio source data from the memory 10 to the digital signal processor 20, or the digital signal There is a problem with the processor 20 or the codec 30. In the case where the audio source data has been excluded, or the path of the audio source data from the memory 10 to the digital signal processor 20, or the digital signal processor 20 has a problem, the codec may be determined 30 There is a problem.

On the other hand, if in step S53, the detection data is inconsistent with the playback data, it means that the problem may only exist on the last element that the signal path passes through, that is, the speaker 40 .

It can be understood that the detection microphone 50 is a standard component, and a high-quality and stable device should be used to avoid affecting the detection result.
