Further, based on the first embodiment, a second embodiment of the testing method for earphones according to the present invention is proposed, and in this embodiment, the step S30 includes:
step S301, carrying out endpoint detection on the feedback audio data to obtain an audio signal;
in this embodiment, the anomaly detection item may include a mutation point detection item, and the test audio data may include a frequency sweep tone for the detection item. The frequency sweeping sound is a sound signal with frequency continuously changing from high to low (or from low to high) in a frequency band.
The testing device may perform endpoint detection on the feedback audio data to obtain an audio signal, that is, some non-audio signals collected due to the delay of the playing of the headphone system may exist in the feedback audio data, and the audio signal is extracted by the endpoint detection. The specific implementation of endpoint detection is not limited herein.
Step S302, framing the audio signal, and calculating an energy difference value between two adjacent framed signals;
after the audio signals are extracted, the test equipment may frame the audio signals to obtain respective framed signals. The frame length may be set in advance according to needs, and is not limited in this embodiment, and may be set to 5ms, for example. The test equipment may calculate an energy value for each of the framing signals. In a specific embodiment, the calculating the energy value of the framing signal may be calculating the energy value of each frequency band in the framing signal, or calculating a weighted average of the energy values of each frequency band of the framing signal. And the testing equipment calculates the difference value of the energy values of the two adjacent framing signals to obtain the energy difference value. In a specific embodiment, if the energy values of the framing signals include energy values corresponding to respective frequency bands, the energy values of the same frequency bands of two adjacent framing signals may be calculated to obtain energy difference values corresponding to respective frequency bands when calculating the energy difference values.
Step S303, when the energy difference value is larger than a preset mutation threshold value, obtaining a test result representing that an abnormal mutation point exists in the feedback audio data;
and the testing equipment compares the energy difference value of the two framing signals with a preset mutation threshold value. In a specific embodiment, when the energy difference value of the two framing signals includes an energy difference value corresponding to each frequency band, the preset abrupt change threshold may include an abrupt change threshold corresponding to each frequency band, and the test device compares the energy difference value of each frequency band with the corresponding abrupt change threshold to obtain a comparison result corresponding to each frequency band.
Because the energy spectrum of the sweep frequency tone is uniformly changed, under the normal condition, the energy difference value between two adjacent framing signals cannot exceed the preset mutation threshold value, and when the energy difference value is greater than the preset mutation threshold value, the abnormal mutation point exists in the feedback audio data. It should be noted that, in a specific embodiment, when the comparison result between the energy difference value of the two framing signals and the preset abrupt change threshold includes the comparison result corresponding to each frequency band, the test result representing that the abnormal abrupt change point exists in the feedback audio data may be obtained when the energy difference value corresponding to at least one frequency band is greater than the corresponding abrupt change threshold.
Step S304, when the energy difference value is smaller than or equal to the preset mutation threshold value, obtaining a test result representing that abnormal mutation points do not exist in the feedback audio data.
And when the energy difference value between two adjacent framing signals is smaller than or equal to a preset mutation threshold, the energy fluctuation is in a normal range, and abnormal mutation points do not exist in the feedback audio data. It should be noted that, in a specific embodiment, when the comparison result between the energy difference value of the two framing signals and the preset abrupt change threshold includes a comparison result corresponding to each frequency band, the test result indicating that there is no abnormal abrupt change point in the feedback audio data may be obtained when the energy difference value corresponding to each frequency band is less than or equal to the corresponding abrupt change threshold.
Further, in a possible implementation manner, after the step S303, the method further includes:
step S305, determining the generation time of the abnormal mutation point according to the acquisition time of a target framing signal, where the target framing signal is two framing signals corresponding to the energy difference value greater than the preset mutation threshold.
In order to facilitate the tester to solve the cause of the abnormal mutation point as soon as possible, in the embodiment, the test equipment may further locate the generation time of the abnormal mutation point. When it is determined that an abnormal abrupt change point exists in the feedback audio data, it is indicated that an energy difference value between at least two frame framing signals is greater than a preset abrupt change threshold value, and the framing signals with the energy difference value greater than the preset abrupt change threshold value are referred to as target framing signals for distinguishing. The test equipment can acquire the acquisition time of the target framing signal and determine the generation time of the abnormal mutation point according to the acquisition time. In a specific embodiment, the determining, by the testing device, the generation time of the abnormal discontinuity point according to the collecting time may specifically be directly taking the collecting time as the generation time of the abnormal discontinuity point, or may also be subtracting, from the collecting time, a sending start time for starting sending the test audio data to the earphone system to obtain a relative time, and taking the relative time as the generation time of the abnormal discontinuity point. After the generation time is obtained, the test equipment can output the generation time and the test result together, so that a tester can find a solution as soon as possible according to the test result and the generation time of the abnormal mutation point.
Further, based on the first and/or second embodiment, a third embodiment of the testing method for earphones according to the present invention is proposed, and in this embodiment, the step S30 includes:
step S311, performing endpoint detection on the feedback audio data, and determining a start time of an audio signal in the feedback audio data;
in this embodiment, the abnormality detection item may include a play delay detection item, that is, a delay from when audio data is transmitted to the headphone system to when the headphone apparatus plays the audio data is detected. The test equipment may perform endpoint detection on the feedback audio data to determine a start time of the feedback audio signal in the feedback audio data. In a specific embodiment, the acquisition time of the signal in the feedback audio data may be recorded by a signal acquisition device, and after the feedback audio signal is obtained by performing endpoint detection on the feedback audio data, the acquisition time corresponding to the starting point of the feedback audio signal is used as the starting time of the feedback audio signal in the feedback audio data.
Step S312, calculating a time difference between the start time and the transmission start time of the test audio data;
the test device may record a transmission start time for transmitting test audio data to the headset system via bluetooth communication. In a specific embodiment, when the test device is test audio data forwarded by other devices, for example, when the test audio data is sent to the headset system through a smart phone, the test device may obtain the sending start time of the test audio data recorded by the test device from the other devices.
And step 313, obtaining a test result of the earphone system about the play delay detection item according to the time difference.
In this embodiment, the specific manner of obtaining the test result of the headphone system regarding the play delay detection item according to the time difference is not limited. In a specific embodiment, after calculating the time difference between the start time of the feedback audio signal and the transmission start time of the test audio data, the test device may directly use the time difference as a test result of the headphone system regarding the playback delay detection item, or may compare the time difference with a threshold value to obtain a test result of whether the delay of the audio playback path of the headphone system is normal.
Further, in a possible implementation, the step S313 includes:
step S3131, when the time difference is greater than a preset delay threshold, obtaining a test result representing that the delay of an audio playing channel of the earphone system is abnormal;
the preset delay threshold may be set in advance as needed.

step S321, obtaining the delay time of the audio playing channel of the earphone system, and aligning the feedback audio data with the test audio data according to the delay time;
in this embodiment, the abnormal detection item may include a noise introduction detection item, that is, whether abnormal noise is introduced in an audio playback path from when audio data is transmitted to the headphone system to when the headphone apparatus plays the audio data is detected. The test device may obtain a delay time of an audio playback path of the headphone system. In this embodiment, the manner of obtaining the delay time is not limited, for example, in a possible implementation, the time difference calculated by the above steps S311 and S312 may be used as the delay time of the audio playing path of the headphone system.
The test device may align the feedback audio data with the test audio data according to the delay time, that is, the delay time may be subtracted from the acquisition time of the feedback audio data to eliminate the influence caused by the delay of the audio playback path.

Step S323, when the similarity is smaller than a preset noise introduction threshold, obtaining a test result representing the noise introduction abnormity of the audio playing channel;
the preset noise introduction threshold may be set in advance as needed. The test equipment can compare the similarity between the aligned feedback audio data and the test audio data with a preset noise introduction threshold, and when the similarity is smaller than the preset noise introduction threshold, it indicates that more signal components different from the test audio data in the feedback audio data are more, more noise is introduced, and the test equipment belongs to an abnormal range.
Step S324, when the similarity is greater than or equal to the preset noise introducing threshold, obtaining a test result indicating that the noise introducing of the audio playing path is normal.
When the similarity is greater than or equal to the preset noise introduction threshold, the consistency of the feedback audio data and the test audio data is high, and the introduced noise is in a normal range, at the moment, the test equipment can obtain a test result that the noise of the audio playing channel of the earphone system is introduced normally.
