Fig. 3 schematically shows a flow chart of a method of testing an electronic device according to another embodiment of the present disclosure. Specifically, fig. 3 illustrates a specific operation procedure of operation S230 in the test method of the electronic device shown in fig. 2.
As shown in fig. 3, the analyzing the signal components of the audio file in operation S230 includes:
in operation S231, the audio record file is converted from a time domain signal to a frequency domain signal.
In this operation, the audio file may be converted from a time domain signal to a frequency domain signal by various time-frequency transformation methods, such as Fourier transform (Fourier transform), Laplace transform (Laplace transform), z-transform (z-transform), and the like, which are not limited herein. For example, in this example, a fast fourier transform is used for time-frequency conversion.
In operation S232, frequency components of a first frequency and frequency components of a second frequency are respectively extracted from the frequency domain signal.
In operation S233, when a frequency component of a first frequency, of which the amplitude value exceeds a first threshold and exceeds the amplitude value of a frequency component of a first predetermined ratio in the frequency domain signal, is extracted, it is determined that the audio record file contains a signal component of the first frequency that satisfies a first predetermined condition.
In operation S234, when a frequency component of a second frequency, of which the amplitude value exceeds a second threshold and exceeds the amplitude value of the frequency component of a second predetermined ratio in the frequency domain signal, is extracted, it is determined that the audio record file contains a signal component of the second frequency that satisfies a second predetermined condition.
Fig. 2 to 3 are explained below with reference to fig. 4A to 4B as a specific example:
fig. 4A schematically shows a schematic diagram of a time domain signal of an audio record file according to an embodiment of the present disclosure.
As shown in FIG. 4A, the time domain signal x (t) of the sound recording file in this example is composed of five sinusoidal signals with different frequencies, signal S1Has a frequency of f1(Hz), signal S2At a frequency off2(Hz), signal S3Has a frequency of f3(Hz), signal S4Has a frequency of f4(Hz), signal S5Has a frequency of f5(Hz). Wherein f is1＜f2＜f3＜f4＜f5。
The time domain signal x (t) shown in fig. 4A is converted into a frequency domain signal x (f) by inverse fast fourier transform, resulting in the spectrogram shown in fig. 4B.
FIG. 4B schematically shows a schematic diagram of a frequency domain signal of an audio record file according to an embodiment of the present disclosure.
As shown in fig. 4B, 5 frequency components are shown in the spectrogram: frequency component 1, frequency component 2, frequency component 3, frequency component 4, and frequency component 5. Wherein the frequency of the frequency component 1 is f1(Hz) and the frequency of the frequency component 2 is f2(Hz) and the frequency of the frequency component 3 is f3(Hz) and the frequency of the frequency component 4 is f4(Hz) and the frequency of the frequency component 5 is f5(Hz). Amplitude value of frequency component 1 is X1(dB), the amplitude value of the frequency component 2 is X2(dB), the amplitude value of the frequency component 3 is X3(dB), the amplitude value of the frequency component 4 is X4(dB), the amplitude value of the frequency component 5 is X5(dB)。
In this embodiment, the first frequency is f1(Hz) and a second frequency of f2(Hz). The first threshold value is a (db), the first predetermined proportion is 80%, the second threshold value is b (db), and the second predetermined proportion is 60%.
The frequency component 1 of the first frequency and the frequency component 2 of the second frequency can be extracted from the spectrogram shown in fig. 4B. Amplitude value X of frequency component 11(dB) exceeds A (dB) and the amplitude value X of the frequency component 11(dB) exceeding the amplitude values of the frequency components (80% × 5 ═ 4) of the first predetermined ratio in the spectrogram, it is determined that the left channel playback effect of the electronic device to be detected is normal2(dB) exceeds B (dB) and the amplitude value X of the frequency component 22(dB) the amplitude of the frequency components exceeding the second predetermined proportion in the spectrogram (i.e. 60% × 5-3 frequency components)And when the value is the same, determining that the right channel playing effect of the electronic equipment to be detected is normal.
It can be known that the frequency component 1 in the spectrogram shown in fig. 4B represents the left channel audio with a fixed first frequency played by the electronic device, the frequency component 2 represents the right channel audio with a fixed second frequency played by the electronic device, and the frequency components 3, 4, and 5 represent the periodic interference noise (from the external environment or the electronic device itself) mixed when the electronic device plays the audio. When the frequency component of the first frequency and the frequency component of the second frequency in the spectrogram are main frequency components of the sound recording file, it is indicated that the playing effect of the left channel and the right channel of the electronic device is normal. In a perfect ideal case, the spectrogram of the audio recording file played by the electronic device only includes the frequency components of the first frequency and the frequency components of the second frequency. It should be noted that fig. 4A to 4B are only examples and are intended to use a simpler model to illustrate the implementation principle of the present disclosure, in other embodiments, the time domain signal of the sound recording file may be other periodic or non-periodic signals in various forms, and a corresponding frequency domain signal is obtained after time-frequency transformation, and the frequency component of the first frequency and the frequency component of the second frequency are extracted from the frequency domain signal to implement simultaneous testing of the audio playing function of the left channel and the right channel of the electronic device, which is not limited herein.
Further, the method shown in fig. 2 and 3 further includes an operation S260 of determining that the left channel of the electronic device is abnormal when the sound recording file does not include a signal component of the first frequency satisfying the first predetermined condition, and outputting a first prompt message. And when the sound recording file does not contain a signal component of a second frequency meeting a second preset condition, determining that the right channel of the electronic equipment is tested abnormally, and outputting second prompt information.
That is to say, if it is detected that the frequency component of the first frequency and/or the frequency component of the second frequency in the spectrogram of the audio record file played by the electronic device is annihilated by the frequency components of other noises, it is indicated that the playing effect of the left channel and/or the right channel of the electronic device is abnormal, a large amount of interference noises are played, and a corresponding prompt needs to be performed.
The implementation of fig. 2 to 3 is illustrated by way of an example:
for example, the testing method of the electronic device shown in fig. 2 to 3 is applied to a computer device, and the electronic device to be tested is a smart speaker. The computer device may communicate with the electronic device to be tested through various communication interfaces such as a UART (Universal Asynchronous Receiver/Transmitter) interface, a COM (Serial communication) port, or a USB (Universal Serial Bus) interface. In this embodiment, the electronic device to be tested is a smart speaker. At the beginning of the test, the computer device sends a control command to the smart speaker through one of the communication interfaces, instructing the smart speaker to play a specified audio file in a linear output (LINEOUT) mode, where the specified audio file includes a left channel audio and a right channel audio, the left channel audio has a first frequency, the right channel audio has a second frequency, in this case, the first frequency is 1KHz, and the second frequency is 2 KHz. The specified audio file may be stored in the smart speaker in advance, or may be generated by using audio generation software in the smart speaker before the test is started, or may be generated in the computer device and then sent to the smart speaker, which is not limited herein. The linear output mode of the electronic equipment is a standard analog output mode of non-power output, and generally has a relatively high level signal and a relatively large signal internal resistance. And after the computer equipment sends a control command to the intelligent sound box, the recording function is started at the same time. The computer equipment records the audio played by the intelligent sound box based on the recording function to obtain a recording file. Specifically, the recording process can be completed by using the recording function of the computer device. And then, analyzing the sound recording file, and determining that the left channel playing effect of the LINEOUT output port of the intelligent sound box is normal when the frequency domain signal of the sound recording file comprises a frequency component of 1KHz meeting a first preset condition. Similarly, when the frequency domain signal of the sound recording file comprises the frequency component of 2KHz meeting the second preset condition, the right channel playing effect of the LINEOUT output port of the intelligent sound box is determined to be normal.
Therefore, through the process, the functional test of the LINEOUT output port of the electronic equipment can be realized only by equipping the electronic equipment to be tested with one upper computer, the configuration is simple, the logic is reasonable, and the requirement of mass test is met. In other embodiments, the functional test of other audio output ports of the electronic device may be implemented according to the present solution, which is not limited herein.
