Detailed ways

The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

An embodiment of the present application provides an audio test method, the audio test method is applied to an audio test system, the audio test system includes a control device and audio test equipment, the audio test equipment includes earphones and a first terminal, earphones and a first terminal, and a control device During the test, the earphone is used as the audio output device of the first terminal, the earphone can be a wireless earphone or a wired earphone, and the execution body of the method in the embodiment of the present application can be a control device. As shown in Figure 1, audio testing methods include:

Step 1001, generating and outputting a preset audio to an audio test device, the preset audio includes multiple frequency components, and the energy levels between the multiple frequency components have a preset relationship;

That is, the preset audio is a signal with multiple frequency components and the internal frequency components form a certain characteristic distribution, and its expression is as follows:

F(s)＝k ₁ *f ₁ (s)+k ₂ *f ₂ (s)+…+k _n-1 *f _n-1 (s)+k _n *f _n (s)

Where f _x (s) represents a specific frequency component, k _n represents the energy of the frequency component, if 0db is the maximum energy of the signal, then all k _x *f _x (s)<0db, the value of x is 1 , 2, ..., n.

The preset relationship is the relationship among k ₁ , k ₂ , . . . , k _n , and the preset relationship can be represented by a function M(n). As shown in Figure 2, taking a 4-segment audio signal as the preset audio as an example, the signal is a single-frequency signal of 500-650hz in the time domain, and the duration of each signal is 1s, of which the first segment and the third segment The signal amplitudes are the same, and the signal amplitudes of the second segment and the fourth segment are the same.

There is no limit to the way of outputting the preset audio to the audio test equipment. For example, the preset audio can be played through the stereo, and the microphone input through the earphone, that is, for the earphone, the preset audio can be used as the uplink data input; Directly transmit the preset audio to the first terminal through wired or wireless communication, and the first terminal plays the preset audio, so as to transmit the preset audio to the earphone, or play the preset audio through the speaker, and pass the first terminal’s The microphone inputs the preset audio, that is, for the headset, the preset audio can be used as downlink data input.

Step 1002, obtaining the test audio data output by the audio test equipment;

After the preset audio is output to the audio test equipment, the preset audio signal will be transmitted in the audio test equipment. During the transmission process, noise may be introduced. After the preset audio is transmitted in the audio test equipment, it will be recorded. To test audio data output, the test audio data will include preset audio and noise introduced during the transfer process. During the transmission of preset audio, the preset relationship will not change significantly as the volume changes. From the input of the preset audio signal to the output of the final test audio data, there are G(s) obtained by linear superposition of several transfer functions, and G(s) finally approximates a constant K (which can be regarded as a gain), that is, the G( s) can be obtained by performing linear superposition of transfer functions.

Step 1003, process the test audio data, convert the test audio data from the time domain expression form to the frequency domain expression form, and obtain the processed audio signal, the processing process can be specifically Fourier transform, such as fast Fourier transform ( Fast Fourier Transform, FFT);

Step 1004, according to the preset relationship, extract the signal to be judged from the processed audio signal;

As shown in Figure 3, assuming that FFT processing is performed on the audio signal shown in Figure 2, it can be seen from the frequency domain diagram that since the duration of each segment of the signal is the same, the amplitude of the 1st and 3rd segment signals is the same, so the accumulated energy is the same. Therefore, the energy of the signal component with a frequency of 500hz is similar to that of the signal component of 600hz, and the energy of the signal at 550hz and 650hz is close. And there are differences between the 1, 3 combination, 2, 4 group signals. The energy relationship inside the signal still exists after the transmission of the audio test equipment. That is to say, assuming that the relationship between the energy of multiple frequency components of the preset audio F(s) is a function M(n), that is, the preset relationship, after obtaining G(s) through the linear superposition of the transfer function, The relationship between the energy magnitudes of multiple frequency components of F(s) is m(n), and M(n)≈m(n) (approximately equal). When performing feature extraction on the test audio data output by the audio test equipment, it can be judged whether the relationship between the energy magnitudes of the various frequency components approximately satisfies M(n).

Step 1005: Determine the test result according to the signal to be judged. After identifying and extracting the signal to be judged corresponding to the original input preset audio, the validity of the input signal can be determined based on the signal. Since the pre-specified frequency components must satisfy the internal relationship M(n), abnormal output results such as discontinuities, freezes, and start delays can also be well identified by the algorithm. The discontinuous anomalies shown in Figure 4 can be identified by The algorithm does a good job of identifying it.

In the audio testing method in the embodiment of the present application, by constructing the audio with the preset relationship between the energy of the frequency components as the input signal of the audio testing equipment, after the signal is transmitted in the audio testing equipment, it can be tested according to this preset relationship Signal identification and extraction can realize automated audio testing based on application scenarios, saving manpower and improving efficiency; this method does not require massive data for calculation, and is flexible for signal construction, and for feature extraction of signals with known preset relationships It is easier to judge and judge, and the recognition accuracy is high; moreover, this method is not sensitive to the sound level, no matter how the gain changes, the energy level between the frequency components remains approximately unchanged; there are noises and other environments in the test environment within a certain range Noise has little effect on this method.

In some possible implementations, the audio testing method in the above-mentioned embodiments can be applied to the multi-scenario and multi-service testing process. At this time, the preset frequency band can be set for the preset audio, which is generated and output in the above step 1001. To the preset frequency band corresponding to the preset audio frequency of the audio test equipment, the above step 1004 is specifically to extract the signal to be judged in the processed audio signal according to the preset frequency band and the preset relationship, that is, when performing feature extraction, it is necessary to judge the preset Whether each frequency component exists, and whether the relationship between the energy magnitudes of each frequency component approximately satisfies M(n). Specific examples are given below.

For example, in the multi-scenario test process, there are two sets of audio test equipment that are tested simultaneously in the same space. The test equipment may receive the other party's audio, which may adversely affect the test results. Therefore, for this multi-scenario testing process, in the above step 1004, the signal to be judged in the processed audio signal may be extracted according to the preset audio and its corresponding preset relationship. Assuming that the preset audio corresponding to the A audio test device belongs to the A frequency band, and the preset audio corresponding to the B audio test device belongs to the B frequency band, and the A frequency band and the B frequency band are different and have no overlap, the audio signals obtained by both include two frequency bands at the same time When extracting the audio signal obtained by the A audio test equipment, it is only extracted in the A frequency band. In this way, the influence of the audio signal corresponding to the B audio test equipment can be eliminated. Similarly, in the B audio test When the audio signal obtained by the equipment is extracted, it is only extracted in the B frequency band, so that the influence of the audio signal corresponding to the A audio test equipment can be eliminated, that is, the multi-scenario test can be realized more efficiently.

For example, in the multi-service testing process, the same set of audio testing equipment needs to acquire preset audio corresponding to at least two services and judge the test results. In order to correctly identify and separately extract audio signals corresponding to different services, the following method can be used for testing.

Assume that the audio signal corresponding to the C service belongs to the C frequency band, and the energy between multiple frequency components has a C preset relationship, and the audio signal corresponding to the D service belongs to the D frequency band, and the energy between multiple frequency components has a D preset relationship. Assuming a relationship, the C frequency band and the D frequency band are different and have no overlap, and the preset audio includes the audio signal corresponding to the C service and the audio signal corresponding to the D service. Then, for the processed audio signal, it can be extracted according to the preset relationship between the C frequency band and C The signal to be judged corresponding to the C service is extracted according to the D frequency band and D preset relationship. Since the signals corresponding to different services are extracted separately, the signals corresponding to different services can be judged in a targeted manner Is it as expected. It should be noted that, in addition to being applicable to the multi-scenario and multi-service testing process, in the scheme of extracting the signal to be judged from the processed audio signal according to the preset frequency band and preset relationship, due to the pre-specified frequency component must exist, common abnormal output results such as silence, howling, and buzzing can be well identified by the algorithm, as shown in Figure 5, the above algorithm can extract the signal to be judged from environmental noise such as white noise and pink noise In other words, even if the testing process is not applied to multiple scenarios or multiple services, the accuracy of the test can be improved.

The embodiment of the present application also provides an audio test system, including: a control device, the control device includes a processor and a memory, and the memory is used to store at least one instruction, and when the instruction is loaded and executed by the processor, it can realize the control device in any embodiment of the present application. Audio testing method, that is to say, the executive body of the audio testing method involved in the above-mentioned Figure 1 can be a control device; the audio testing equipment is connected to the control device in communication, and the audio testing equipment includes: earphones, and the earphones are connected to the control device in communication; A terminal, a communication connection between the first terminal and the control device, for example, the first terminal and the control device may have a Bluetooth connection function to realize the communication connection between the first terminal and the control device.

It should be noted that the above only introduces the basic audio test method and its corresponding audio test system. On this basis, the audio test method can have a more complicated process, and the audio test system can have more functions and devices. The audio test system and the audio test method in other possible implementations will be further described below.

In fact, the difference between the method shown in FIG. 13 and the method shown in FIG. 11 is that the call recording signal is recorded by the first terminal 61 as the test audio data, so that the signal distortion introduced by the communication process of the call connection can be avoided. And other issues.

For audio signals in which multiple groups of audio signals are aliased and accompanied by noise, the above method can also be used for input signal construction and output signal feature extraction. For example, it is assumed that the first preset audio frequency is a signal composed of 500-650 Hz frequency components, and the second preset audio frequency is a signal composed of 1000-1150 Hz frequency components with pink noise signals. In the spectrogram obtained by FFT, the frequency components of the two groups of signals are preserved, and the relationship of each frequency component in the group also approximately satisfies the corresponding preset relationship. That is to say, in the above-mentioned various scenarios, multiple sets of preset audio can be input, and through the transmission of the audio test equipment, the obtained test audio data includes multiple sets of audio signals mixed with audio signals accompanied by noise. Groups of audio signals can be distinguished by corresponding frequency bands. Therefore, through the method in the embodiment of the present application, signals to be judged corresponding to different groups of audio signals can still be extracted and identified respectively. This method realizes the test of multi-service scenarios, such as a sudden call or an alarm ringing during music playback.

Specifically, in the same space, there is a superposition effect of sound, and the audio test equipment works at the same time. For example, in the scene of a call or recording, the played audio signals will affect each other and be input as noise signals of other systems. In this embodiment, different frequency bands and signals with different component relationship descriptions are selected as input, that is, the frequency bands between different preset audio frequencies are mutually exclusive (no intersection). In this way, even if the preset audio frequencies are input to other test equipment, due to different The frequency bands between them are different, so when extracting the identification signal, different input signals can still be distinguished, so the test results of the audio test equipment will not be interfered by other equipment.

In the above scenarios, the audio signals are linearly superimposed, so G(s) is close to the constant K within a fixed time. Summarize the above scenarios, covering the main delivery scenarios of mobile phones and wireless audio headsets, such as playback category: music playback, prompt tone (SMS, alarm, incoming call ringtone); recording category: recorder, WeChat voice message; call category: typical two-way conversation , Wechat audio/video call, video conference call; signal aliasing: the sound of the prompt in the music, the sound of the prompt in the call, etc.

In order to enable the input preset audio to be more accurately recognized by the recognition algorithm when it is output after passing through the transfer function, it can have the following characteristics:

3. The input audio signal needs to have a certain characteristic law, and its characteristic internal law will not change significantly as the volume becomes larger or smaller;

4.

The embodiments of the present application will be described below through some more specific embodiments.

As shown in Figure 19, the embodiment of the present application provides an audio test method that can be used in the above-mentioned audio test system. The audio test method includes:

The multi-service test refers to the test involving multiple For the wireless headset test in the scenario where the wireless headset service is used, the touch test refers to the test based on the touch function of the wireless headset, and the wearing test refers to the function trigger test based on the wearing state of the wireless headset.

In a possible implementation manner, the call test includes:

Step 201, the control device 1 sends corresponding call instructions to the first terminal 61 and the second terminal 62;

Step 202, the first terminal 61 and the second terminal 62 establish a call connection in response to the corresponding call instruction. The call here can be various types of instant voice calls such as telephone calls, Internet voice calls, and Internet video calls. Take a call as an example to illustrate;

After the call connection is established between the first terminal 61 and the second terminal 62, perform a downlink call test and/or an uplink call test;

Downlink testing includes:

Step 203, the control device 1 controls the first terminal 61 to turn off the microphone and controls the stereo 5 to play preset audio, so that the preset audio played by the stereo 5 is input to the second terminal 62, and controlling the first terminal 61 to turn off the microphone can also be said to control the first Terminal 61 is muted, and the first terminal 61 cannot input through its own microphone or the microphone of the connected wireless earphone 2. Therefore, the audio played through the audio system 5 will be input through the microphone of the second terminal 62, and cannot be input through the first terminal 61. Terminal 61 input;

During the process of playing preset audio by the audio system 5 , in step 204 , the control device 1 controls the two-channel sound card 4 to record the sound collected by the artificial ear 3 as downlink audio data, and the downlink audio data is test audio data.

That is to say, in the downlink call test, after the preset audio played by the stereo 5 is input to the second terminal 62, it is transmitted to the first terminal 61 through the call connection, and then transmitted to the wireless earphone 2 for playback through the first terminal 61, and then It is collected by the artificial ear 3, and then recorded as downlink audio data through the two-channel sound card 4. After that, the control device 1 can judge the validity according to the downlink audio data, and realize the audio test under the downlink call scene;

Uplink call tests include:

Step 205, the control device 1 controls the second terminal 62 to turn off the microphone and controls the stereo 5 to play preset audio, so that the preset audio played by the stereo 5 is input into the microphone of the wireless headset 2, and the test method includes both the downlink call test and the uplink call test , the preset audio in the downlink call test and uplink call test can be the same or different;

During the process of playing the preset audio by the stereo, in step 206, the control device 1 controls the second terminal 62 to record the audio during the call as uplink audio data, and the uplink audio data is test audio data.

That is to say, in the uplink call test, the preset audio played by the audio system 5 is input into the microphone of the wireless earphone 2, and is transmitted to the first terminal 61 through the Bluetooth connection between the wireless earphone 2 and the first terminal 61, and then through the second terminal 61. The call connection between a terminal 61 and the second terminal 62 is transmitted to the second terminal 62, and then the call recording of the second terminal 62 is recorded as uplink audio data, and then the second terminal 62 can transmit the uplink audio data to the control device 1. The control device 1 can judge the validity according to the uplink audio data, so as to realize whether the uplink and downlink of the wireless headset as the terminal audio is normal in the voice call scene.

The audio test system and method in the embodiment of the present application can realize the audio test in the call scene based on the wireless earphone through the control of each device by the control device, and can realize the automatic test by replacing the corresponding manual operation and test scene construction. Audio testing based on application scenarios saves manpower and improves efficiency.

In a possible implementation manner, as shown in FIG. 20, after the call connection is established between the first terminal 61 and the second terminal 62, a downlink call test is performed, and an uplink call test is performed after the downlink call test is performed; Before the control device 1 controls the stereo 5 to play the preset audio, the downlink call test further includes the control device 1 controlling the first terminal 61 to record the audio during the call as reference audio data.

Specifically, for example, the above step 101 includes: the control device 1 sends an unpacking and pairing instruction to the wireless headset 2, the control device 1 sends a bluetooth device scanning command with a specified name to the first terminal 61, and the specified name is the name of the wireless headset 2; Step 102 includes: the wireless earphone 2 enters the pairing mode in response to the pairing instruction of opening the box, and the first terminal 61 responds to the bluetooth device scanning instruction to start scanning the bluetooth device of the specified name, and when the first terminal 61 scans the wireless earphone 2, then pairing, Establish a Bluetooth connection between the first terminal 61 and the wireless headset 2; step 201 includes: the control device 1 sends a call instruction to the first terminal 61, and the control terminal 1 sends an answer instruction to the second terminal 62; step 202 includes: The first terminal 61 makes a call to the second terminal 62 in response to the dialing instruction, and the second terminal 62 answers the call in response to the instruction of answering the call, so as to establish a call connection between the first terminal 61 and the second terminal 62; step 203 includes: After the two terminals establish a call connection, the control device 1 controls the first terminal 61 to turn off the microphone and turn on the call recording, so as to record the audio during the call as reference audio data, and the control device 1 controls the audio 5 to play the preset audio, and the audio 5. The preset audio played will be input through the microphone of the second terminal 62; step 204 includes: the control device 1 controls the two-channel sound card 4 to record the sound collected by the artificial ear 3 as downlink audio data; after that, the first terminal 61 ends Call recording, unmute, upload the call recording to the control device 1, the call recording is the reference audio data; after that, step 205 includes: the control device 1 controls the second terminal 62 to turn off the microphone and open the call recording, the recorded audio is Uplink audio data; the control device 1 controls the stereo 5 to play preset audio, and the preset audio played by the stereo 5 will be input through the microphone of the wireless earphone 2; after that, the second terminal 62 ends the call and uploads the recorded uplink audio data To the control device 1, that is, step 206 includes that the control device 1 controls the second terminal 62 to record the audio during the call as uplink audio data; the control device 1 judges the validity of the audio signal through the call recording and the audio data recorded by the two-channel sound card.

The validity of the audio signal can be judged based on the played preset audio source. For example, the preset audio is a signal with multiple frequency components and the internal frequency components have a certain characteristic distribution. For the recorded uplink audio data and downlink audio data, it will contain the frequency characteristics of the preset audio, therefore, signal extraction and judgment can be performed on the recorded audio data according to the frequency characteristics.

However, the downlink audio data is that the preset audio played by the audio system 5 is input to the second terminal 62, and then transmitted to the first terminal 61 through a call connection, and then transmitted to the wireless earphone 2 for playback through the first terminal 61, and then received by the artificial ear 3. Collected and then recorded through the two-channel sound card 4, the communication transmission process of the call connection may introduce problems such as signal distortion in the communication process, and this distortion may lead to inaccurate signal extraction and judgment based on frequency characteristics , therefore, in order to improve the problem of low judgment accuracy caused by it, it is possible to introduce the reference audio data obtained by recording the call on the first terminal 61 side. Since the reference audio data also introduces the distortion effect in the communication process, therefore, it can be The extraction and judgment of the audio signal are corrected according to the reference audio data, so as to improve the judgment accuracy.

For similar reasons, uplink audio data also has the problem of inaccurate signal extraction and judgment due to distortion in the communication process. In order to improve this problem, in a possible implementation manner, the acquisition of uplink audio data can be obtained through the recording of the first terminal 61 instead, so that the adverse effects caused by the distortion introduced by the terminal communication process can be eliminated.

In a possible implementation, as shown in FIGS. 21 to 23 , the audio test system further includes: a shielding container 7 , the shielding container 7 has a cover, and the shielding container 7 is used to shield wireless signals when the cover is closed. The Bluetooth connection module of one of the earphone 2 and the first terminal 61 is arranged in the shielding container 7, and the Bluetooth connection module of the other of the wireless earphone 2 and the first terminal 61 is arranged outside the shielding container 7; the shielding container 7 also Can include a container control mechanism 8, the container control mechanism 8 is used to control the opening and closing of the cover, the container control mechanism 8 is connected to the control device 1 by communication; the container control mechanism 8 can realize the opening and closing of the cover through the push rod mechanism shown in Figure 7 Opening and closing control, in addition, the container control mechanism 8 can also include the driving device for driving the push rod mechanism, the driving device can include the bottom power supply circuit and the driving circuit, the driving device can be a separate electric control box, the driving device Electrically connected to the push rod structure and the control device 1, that is, the container control mechanism 8 can realize the communication connection with the control device 1 through the drive device; in addition, the container control mechanism 8 can also include a limit sensor, which is used for Sensing the position of the cover and feedback control the push rod mechanism, for example, control the push rod mechanism to stop when the limit sensor senses that the cover is closed in place, or control the push rod mechanism when the limit sensor senses that the cover is opened in place stop motion.

Specifically, for example, the first terminal 61 is arranged in the shielding container 7, and the wireless earphone 2 is arranged outside the shielding container 7. When the cover of the shielding container 7 is closed, due to the shielding effect of the shielding container 7 on the Bluetooth signal, The Bluetooth connection between the wireless earphone 2 and the first terminal 61 will be disconnected, and when the cover of the shielding container 7 is opened, the wireless earphone 2 can maintain the Bluetooth connection with the first terminal 61 . An interface can be set on the shielding container 7, so that the first terminal 61 can be connected to the outside of the shielding container 7 through the interface through the connection line, and then connected to the control device 1, so that even if the cover of the shielding container 7 is closed, Only wireless signals are shielded, and the communication connection between the control device 1 and the first terminal 61 will not be adversely affected. The shielding container 7 is described with reference to the module division method shown in Figure 7. The modules divided by the test system from the software level also include a shielding container control module. It is an electric control shielding box obtained through electromechanical transformation of ordinary manual shielding boxes (for example, the opening and closing of the shielding box is realized through the control of an electric push-pull rod). The essence of using the shielding container 7 for testing is to use the shielding effect of the shielding container 7 on the Bluetooth signal, so as long as the shielding of the Bluetooth signal can be realized. For the wireless earphone 2 and the first terminal 61, it is necessary to respectively have a Bluetooth connection module to realize the Bluetooth connection function. Respectively placed inside and outside the shielding container 7, also can only place the bluetooth connection module of one of them in the shielding container 7, place the bluetooth connection module of the other outside the shielding container 7, can also carry out based on Bluetooth disconnection and connection test.

Put one of the bluetooth connection module of the wireless earphone 2 (which can be composed of components such as an EVK carrying an audio chip and its headphone speaker) and the bluetooth connection module of the first terminal 61 into the shielding box, through the control device 1 and The Universal Asynchronous Receiver/Transmitter (UART) of the shielding box control board communicates to control the opening and closing of the shielding box, thereby simulating the scene where the wireless connection between the mobile phone and the audio device is disconnected/recovered. That is to say, through the shielding container 7, it is possible to simulate the function of the wireless earphone 2 under the scenario of disconnecting and reconnecting the bluetooth connection between the first terminal 61 and the wireless earphone 2, so that when testing this scenario, There is no need to manually change the distance between the terminal and the wireless earphone to realize the scene construction of disconnection and connection recovery, thereby improving the test efficiency. For an audio test system including a shielding container, the audio test method of the embodiment of the present application can still be used to determine the validity of the audio.

When testing the disconnection and reconnection of the Bluetooth connection, the left ear Bluetooth connection can be The module is placed in the first shielding container, and the right ear Bluetooth connection module is placed in the second shielding container. The artificial ear includes left ear parts and right ear parts, and the artificial ear and the first terminal are placed in the first shielding container and the second shielding container. Outside the container, the left channel speaker is set on the left ear part, and the right channel speaker is set on the right ear part. It should be noted that the essence of using the shielding container 7 for testing is to use the shielding effect of the shielding container 7 on the Bluetooth signal. It may be a device that can realize the function of wireless earphone 2. For example, in the test method of using EVK to replace the chip in the finished earphone mentioned above, the EVK and its connected earphone speakers can be used as wireless earphone 2 for testing. At this time , if there is a Bluetooth connection module in the EVK, the EVK can be placed in the shielding container, and the left ear speaker and the right ear speaker connected to the EVK can be placed outside the shielding container.

Wherein, since the preset audio is pre-set, it can be set that its frequency characteristics are different from those of the prompt tone. In this way, in the multi-scene audio data, the frequency characteristics of the preset audio and the prompt tone can be adjusted. The two are distinguished and identified to judge whether the music playback effect in a multi-service scenario meets expectations.
