Detailed Description
In order to make the objects, features and advantages of the present disclosure more comprehensible, the technical solutions in the embodiments of the present disclosure will be clearly described in conjunction with the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
The embodiment of the disclosure provides a method for automatically testing a buzzer, which is used for extracting a frequency domain signal corresponding to a sound source file from audio information by collecting the audio information generated by playing the sound source file by the buzzer to be tested, and testing the buzzer to be tested based on the frequency domain signal corresponding to the sound source file; meanwhile, human factors are prevented from being introduced in the testing process, and the accuracy of buzzer testing is improved.
Fig. 1 shows a schematic process flow diagram of a method of testing a buzzer in accordance with an embodiment of the present disclosure.
Referring to fig. 1, a process flow of a method for testing a buzzer according to an embodiment of the present disclosure may include at least the following steps:
step S101, collecting audio information generated by a buzzer playing audio file to be tested.
In some embodiments, a sound source file for testing the buzzer to be tested is selected, and playing source information corresponding to the sound source file is obtained. The playing source information at least may include: the amplitude, frequency and duration of the sound source file.
As an example, an audio frequency with an amplitude of 1V, a frequency of 1KHz, and a duration of 1S is selected as the sound source file a of the buzzer to be tested.
In some embodiments, the sound source file played by the buzzer to be tested generates corresponding audio, and the audio information corresponding to the sound source file is generated by collecting the audio generated by the sound source file played by the buzzer to be tested by using the recording device. When the sound source file played by the buzzer to be tested is collected by the recording equipment, external environmental noise is inevitably introduced. Thus, as shown in fig. 2, the audio information may include at least: a source file and a source of noise; audio information corresponding to the source audio file is generated from the source audio file in combination with a plurality of noise sources.
As an example, the buzzer to be tested plays the audio source file a, generates the corresponding audio a ', and utilizes the microphone to collect the audio a', and generates the audio information a corresponding to the audio source file a. Wherein, the audio information a may include at least: a source file a, a noise source 1, a noise source 2, a noise source 3 and a noise source 4.
Step S102, analyzing the audio information to obtain a frequency domain signal corresponding to the audio file.
In some embodiments, the collected audio information is converted from a time domain signal to a frequency domain signal through fourier transformation, noise signal components of other frequencies are filtered according to the frequency of a sound source file in the audio information, and the frequency domain signal components corresponding to the sound source file, and information such as amplitude, duration and the like of the frequency domain signal components are analyzed.
Therefore, the specific implementation process of analyzing the audio information to obtain the frequency domain signal corresponding to the audio file at least includes the following steps:
step S102a, converting the time domain signal in the audio information into a frequency domain signal by fourier transform.
Step S102b, filtering noise signals in the audio information based on the frequency of the sound source file to obtain frequency domain signals corresponding to the sound source file.
As an example, referring to fig. 3, the audio information a is converted from a time domain signal into a frequency domain signal by fourier transformation, noise signal components of other frequencies are filtered according to the frequency of the audio file a, i.e., 1KHz, and the frequency domain signal components corresponding to the audio file a, i.e., 1KHz signal components, and information such as the amplitude and duration of the 1KHz signal components, are resolved. Wherein, figure 3 is divided into a time domain diagram and a frequency domain diagram; the horizontal axis of the Time domain graph represents Time (Time), and the vertical axis represents amplitude (Intensity); the horizontal axis of the Frequency domain diagram represents Frequency (Frequency), and the vertical axis represents amplitude (concentration).
Step S103, comparing the information corresponding to the frequency domain signal with the playing source information corresponding to the audio file to obtain an audio comparison result.
In some embodiments, the audio comparison result is that the comparison is successful under the condition that the amplitude and the duration of the frequency domain signal are consistent with the amplitude, the frequency and the duration in the playing source information; and if the frequency domain signal corresponding to the audio file is not analyzed or the amplitude and the duration of the frequency domain signal are inconsistent with the amplitude, the frequency and the duration of the playing source information, the audio comparison result is failure comparison.
As an example, the amplitude of the 1KHz signal is 1V, the duration is 1S, and the audio comparison result is successful when the amplitude is 1V, the frequency is 1KHz, and the duration is 1S of the audio which is consistent with the playing source information; the audio frequency comparison result is failure when the amplitude of the 1KHz signal is not analyzed or the 1KHz signal is 1V, the duration is 0.8S, and the audio frequency is inconsistent with the playing source information (the amplitude is 1V, the frequency is 1KHz, and the duration is 1S).
Step S104, judging whether the function of the buzzer to be detected is normal or not based on the audio comparison result.
In some embodiments, when the audio comparison result is that the comparison is successful, the buzzer to be tested functions normally; and under the condition that the audio comparison result is that the comparison fails, the buzzer to be tested is abnormal in function.
In the related art, the testing and distinguishing of the buzzer function by the computer board card manufacturer mainly depends on whether the function of the buzzer is normal or not by a tester through human ears. The method for automatically testing the buzzer provided by the embodiment of the disclosure not only can improve the testing efficiency, but also can omit the problem of the yield of products caused by test items and erroneous judgment.
Fig. 4 shows an overall flow diagram of a method of testing a buzzer in accordance with an embodiment of the present disclosure.
Referring to fig. 4, taking an on-board buzzer on a board card as an example, a method for testing a buzzer according to an embodiment of the present disclosure is described as an example.
Building an automatic buzzer test system, and starting the automatic buzzer test; calling a microphone to start a recording function, and playing a sound source file to sound a buzzer; the buzzer is recorded to play the audio information generated by the sound source file, and the audio information is analyzed to obtain a frequency domain signal corresponding to the sound source file; comparing the information corresponding to the frequency domain signal with the playing source information corresponding to the sound source file, if the comparison is successful, the buzzer to be tested functions normally, and if the comparison is failed, the buzzer to be tested functions abnormally; and uploading the test result. Therefore, whether the buzzer on the electronic product board card of the computer, the vehicle-mounted electronic equipment and the like and the electronic components related to the buzzer circuit have faults or defects or not is checked, and the test of the buzzer functional module is realized.
As shown in fig. 5, the components of the buzzer automatic test system may include at least: the device comprises a board card (1) to be tested, an on-board buzzer (2), an external microphone (3) and an on-board Audio interface (Audio Jack) (4).
