Detailed Description
The terminology used in the description section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
The embodiment of the application provides an audio test method, which is applied to an audio test system, wherein the audio test system comprises a control device and audio test equipment, the audio test equipment comprises an earphone and a first terminal, the earphone is in communication connection with the first terminal and the control device, the earphone is used as audio output equipment of the first terminal during test, the earphone can be a wireless earphone or a wired earphone, and an execution main body of the method can be the control device. As shown in fig. 1, the audio test method includes:
step 1001, generating and outputting a preset audio to an audio test device, wherein the preset audio comprises a plurality of frequency components, and the energy magnitudes among the plurality of frequency components have a preset relationship;
that is, the preset audio is a signal having a plurality of frequency components and an internal frequency component having a certain characteristic distribution, and the expression thereof 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)
wherein f x (s) represents a specific frequency component, k n Representing the energy level of the frequency component, if 0db is set as the maximum energy of the signal, all k x *f x (s)<0db, x is 1, 2, …, n.
Preset relation is k 1 、k 2 、…、k n The relation between the two, the preset relation can be expressed by a function M (n). As shown in fig. 2, taking a 4-segment audio signal as an example of the preset audio, the signal is a single-frequency signal of 500-650hz in the time domain, and the duration of each segment of signal is 1s, wherein the amplitude of the first segment signal is the same as that of the third segment signal, and the amplitude of the second segment signal is the same as that of the fourth segment signal.
The manner of outputting the preset audio to the audio test device is not limited herein, for example, the preset audio may be played through sound, and input through a microphone of the earphone, that is, the preset audio may be input as uplink data to the earphone; the preset audio can also be directly transmitted to the first terminal in a wired or wireless communication mode, the first terminal plays the preset audio so as to transmit the preset audio to the earphone, or the preset audio is played through a sound, and the preset audio is input through a microphone of the first terminal, namely, the preset audio can be input as downlink data to the earphone.
Step 1002, obtaining test audio data output by an audio test device;
after the preset audio is output to the audio test equipment, the preset audio signal is transmitted in the audio test equipment, noise may be introduced in the transmission process, the preset audio is recorded as test audio data output after the transmission of the preset audio in the audio test equipment is completed, and the test audio data comprises the preset audio and the noise introduced in the transmission process. In the process of transmitting the preset audio, the preset relation does not change obviously along with the change of the volume. From the input of the preset audio signal to the output of the final test audio data, there are G(s) obtained by linearly superimposing a plurality of transfer functions, and the G(s) finally approximates a constant K (which can be regarded as a gain), that is, the G(s) may be obtained by linearly superimposing transfer functions.
Step 1003, processing the test audio data, converting the test audio data from a time domain expression form to a frequency domain expression form, so as to obtain a processed audio signal, wherein the processing process can be specifically fourier transformation, such as fast fourier transformation (Fast Fourier Transform, FFT);
step 1004, extracting a signal to be judged in the processed audio signal according to a preset relation;
As shown in fig. 3, assuming that the audio signal shown in fig. 2 is subjected to FFT processing, it is known from the frequency domain diagram that the integrated energy is the same since each signal has the same duration and the 1 and 3 signal amplitudes are the same. The signal components with frequencies of 500hz have energies close to those of 600hz, and the signal energies of 550hz and 650hz are close. And the signals of the groups 1, 3, 2 and 4 are different. The energy relationship within such a signal, after passing through the audio test equipment, remains. That is, it is assumed that the energy magnitudes among the plurality of frequency components of the preset audio F(s) have a relationship of a function M (n), that is, a preset relationship, and that, after G(s) is obtained by linear superposition of transfer functions, the energy magnitudes among the plurality of frequency components of F(s) have a relationship of M (n), M (n) ≡m (n) (approximately equal). When the feature extraction is performed on the test audio data output by the audio test equipment, it can be judged that: whether or not the relation of the energy magnitudes between the respective frequency components approximately satisfies M (n) is sufficient.
Step 1005, determining a test result according to the signal to be determined, and identifying and extracting the signal to be determined corresponding to the preset audio of the original input, so as to determine the validity of the input signal based on the signal. Since the pre-specified frequency components must satisfy the internal relation M (n), the abnormal output results such as interruption, stuck, play-out delay, etc. can be well identified by the algorithm, and the interruption abnormality as shown in fig. 4 can be well identified by the algorithm.
According to the audio test method, the audio with the energy magnitude with the preset relation among the frequency components is constructed as the input signal of the audio test equipment, after the signal is transmitted in the audio test equipment, the signal can be identified and extracted according to the preset relation, so that automatic audio test based on application scenes can be realized, labor is saved, and efficiency is improved; the method does not need massive data to operate, has flexible signal construction, is easier to extract and judge the characteristics of the signals with known preset relations, and has high identification accuracy; moreover, the method is insensitive to the sound size, and the energy size among frequency components is kept approximately unchanged no matter how the gain changes; when noise and other environmental sounds exist in a test environment within a certain range, the influence of the noise on the method is small.
In some possible implementation manners, the audio testing method in the foregoing embodiments may be applied to a multi-scenario and multi-service testing process, where a preset frequency band may be set for a preset audio, that is, the preset audio generated in the foregoing step 1001 and output to an audio testing device corresponds to the preset frequency band, and the foregoing step 1004 specifically includes extracting a signal to be determined in the processed audio signal according to the preset frequency band and a preset relationship, that is, when feature extraction is performed, it needs to determine whether each preset frequency component exists, and whether the relationship of energy sizes between each frequency component approximately satisfies M (n). The following is a specific example.
For example, in a multi-scenario testing process, two sets of audio testing devices are provided to perform testing simultaneously in the same space, and at this time, if a preset audio is output by playing audio in space through sound, the two sets of audio testing devices may receive the audio of the other party, so that the testing result may be adversely affected. Therefore, for such a multi-scenario testing process, in step 1004, the signal to be determined in the processed audio signal may be extracted according to the preset audio and the corresponding preset relationship. The method comprises the steps that when an audio signal obtained by an A audio test device is extracted, the influence of the audio signal corresponding to the B audio test device can be eliminated, similarly, when the audio signal obtained by the B audio test device is extracted, the influence of the audio signal corresponding to the A audio test device can be eliminated, and therefore, the multi-scene test can be more efficiently realized.
For example, in a multi-service testing process, the same set of audio testing equipment needs to acquire preset audio corresponding to at least two services and judge a testing result. In order to correctly identify and extract the audio signals corresponding to different services respectively, the following method may be used for testing.
Assuming that the audio signal corresponding to the C service belongs to the C frequency band, wherein the energy magnitudes among the plurality of frequency components have a C preset relationship, the audio signal corresponding to the D service belongs to the D frequency band, wherein the energy magnitudes among the plurality of frequency components have a D preset relationship, the C frequency band and the D frequency band are different and do not overlap, 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, the signal to be judged corresponding to the C service can be extracted according to the C frequency band and the C preset relationship, and the signal to be judged corresponding to the D service can be extracted according to the D frequency band and the D preset relationship, and because the signals corresponding to the different services are respectively extracted, whether the signals corresponding to the different services meet the expectations can be judged in a targeted manner. It should be noted that, in addition to being applicable to the testing process of multiple scenes and multiple services, in the scheme of extracting the signal to be judged in the processed audio signal according to the preset frequency band and the preset relation, since the pre-designated frequency component must exist, the abnormal output results such as common silence, howling, buzzing and the like can be well identified by the algorithm, as shown in fig. 5, the algorithm can extract the signal to be judged in the environmental noise such as white noise and pink noise, that is, even if the algorithm is not applied to the testing process of multiple scenes or multiple services, the testing accuracy can be improved.
The embodiment of the application also provides an audio test system, which comprises: the control device, the control device includes a processor and a memory, the memory is used for storing at least one instruction, the instruction is loaded and executed by the processor to implement the audio test method in any embodiment of the application, that is, the execution subject of the audio test method referred to in fig. 1 may be the control device; an audio test device communicatively coupled to the control device, the audio test device comprising: the earphone is in communication connection with the control device; the first terminal and the control device are in communication connection, for example, the first terminal and the control device can have a bluetooth connection function, so as to realize communication connection between the first terminal and the control device.

In one possible embodiment, as shown in fig. 16 and 17, the preset audio includes a first preset audio and a second preset audio, the first preset audio corresponds to a first preset frequency band, the second preset audio corresponds to a second preset frequency band, and the first preset frequency band is smaller than the second preset frequency band. For audio signals with noise and aliasing of multiple groups of audio signals, the method can also be used for input signal construction and output signal feature extraction. For example, assume that the first preset audio is a signal composed of frequency components of 500-650hz, and the second preset audio is a signal composed of frequency components of 1000-1150hz, with a pink noise signal. The frequency components of the 2 groups of signals are reserved through the spectrogram obtained through FFT, and the relation of the frequency components in the groups approximately meets the corresponding preset relation. That is, in the above-mentioned various scenarios, multiple sets of preset audio may be input, and through the transmission of the audio test device, the obtained test audio data includes multiple sets of audio signals with aliasing and accompanying noise, and since different sets of audio signals may be distinguished by corresponding frequency bands, the method in the embodiment of the present application may still extract and identify the signals to be determined corresponding to the different sets of audio signals respectively. The method realizes the test of multi-service scenes, such as a sudden incoming call or ringing alarm in the process of playing music.
In each scene, the environmental noise component can be transmitted into the system through a mic or artificial ear, and the final recording file comprises the noise signal frequency component; when audio files of a plurality of frequency components are presented (played) simultaneously, all frequency components will be saved in a linearly superimposed manner with the time shift of the audio track, and thus the output audio file will contain the plurality of frequency components as analyzed from the frequency domain.
In one possible embodiment, as shown in fig. 18, the preset audio includes a third preset audio and a fourth preset audio, the third preset audio corresponds to a third preset frequency band, the fourth preset audio corresponds to a fourth preset frequency band, the third preset frequency band is smaller than the fourth preset frequency band, the energy magnitudes among the plurality of frequency components of the third preset audio have a third preset relationship, and the energy magnitudes among the plurality of frequency components of the fourth preset audio have a fourth preset relationship; the audio test equipment comprises first audio test equipment and second audio test equipment; the method for obtaining the test audio data output by the audio test equipment comprises the following steps: acquiring first test audio data output by first audio test equipment; acquiring second test audio data output by second audio test equipment; processing the test audio data, converting the test audio data from a time domain expression form to a frequency domain expression form, and obtaining a processed audio signal comprises: processing the first test audio data, and converting the first test audio data from a time domain expression form to a frequency domain expression form to obtain a processed first audio signal; processing the second test audio data, and converting the second test audio data from a time domain expression form to a frequency domain expression form to obtain a processed second audio signal; according to the preset frequency band and the preset relation, extracting the signal to be judged in the processed audio signal comprises the following steps: extracting a first signal to be judged in the processed first audio signal according to a third preset frequency band and a third preset relation; extracting a second signal to be judged in the processed second audio signal according to a fourth preset frequency band and a fourth preset relation; determining a test result according to the signal to be judged comprises: and determining a first test result according to the first signal to be judged, and determining a second test result according to the second signal to be judged.
Specifically, in the same space, the sound has superposition effect, and the audio test equipment works simultaneously, for example, when in a call or a recording scene, the played audio signals can influence each other, and the audio signals are input as noise signals of other systems. In this embodiment, different frequency bands are selected and the component relationships describe different signals as inputs, that is, the frequency bands between different preset audios are mutually exclusive (without intersection), so that even if the preset audios are input to other test devices, different input signals can be distinguished when the identification signals are extracted due to different frequency bands between different audios, and therefore the test result of the audio test device cannot be interfered by other devices.
In the above-described various scenes, the audio signals are linearly superimposed, and thus G(s) approaches a constant K in a fixed time. Summarizing the above scenario, the main delivery scenario of the mobile phone and the wireless audio headset is covered, such as play class: music playing, alert tones (short message, alarm, incoming call ring); recording: a recorder, a WeChat voice message; conversation type: typical two-way calls, weChat audio/video calls, video conferencing calls; signal aliasing class: the music and the conversation are provided with a sound prompting tone.
In order to enable the input preset audio to be more accurately identified by an identification algorithm when being output after passing through a transfer function, the method can have the following characteristics:
1. the input audio signal has a clear frequency component and a plurality of frequency components;
2. certain characteristic rules are presented in the frequency components of the input audio signals, so that the characteristic extraction is convenient for an identification algorithm;
3. the input audio signal needs to have a certain characteristic rule, and the characteristic internal rule is not obviously changed along with the increase and decrease of the sound volume;
4. the characteristic frequency energy of the input audio signal needs to be significantly different from the noise signal (here, the noise signal includes white noise/white noise and other generalized level noise), so that the characteristics cannot be submerged in the noise signal and cannot be extracted.
Embodiments of the present application are described below with reference to a few more specific examples.
As shown in fig. 19, an embodiment of the present application provides an audio testing method, which may be used in the above-mentioned audio testing system, where the audio testing method includes:

the downlink call test includes:
step 203, the control device 1 controls the first terminal 61 to close the microphone and controls the audio 5 to play the preset audio, so that the preset audio played by the audio 5 is input to the second terminal 62, and controls the first terminal 61 to close the microphone, so to speak, to control the first terminal 61 to mute, and the first terminal 61 cannot input through its microphone or the microphone of the connected wireless earphone 2, so that the audio played by the audio 5 is input through the microphone of the second terminal 62 and cannot input through the first terminal 61;
in the process of playing the preset audio by the stereo 5, step 204, the control device 1 controls the binaural sound card 4 to record the sound collected by the artificial ear 3 as downlink audio data, and the downlink audio data is the test audio data.
That is, in the downlink call test, after the preset audio played by the stereo 5 is input into the second terminal 62, the audio is transmitted to the first terminal 61 through the call connection, then transmitted to the wireless earphone 2 through the first terminal 61 for playing, then collected by the artificial ear 3, recorded as downlink audio data by the binaural sound card 4, and then the control device 1 can perform validity judgment according to the downlink audio data, so as to realize the audio test in the downlink call scene;
The uplink call test includes:
step 205, the control device 1 controls the second terminal 62 to close the microphone and controls the sound 5 to play the preset audio, so that the preset audio played by the sound 5 is input into the microphone of the wireless earphone 2, and when the test method includes both the downlink call test and the uplink call test, the preset audio in the downlink call test and the uplink call test may be the same or different;
in the process of playing the preset audio, in step 206, the control device 1 controls the second terminal 62 to record the audio in the call process as uplink audio data, where the uplink audio data is the test audio data.
That is, in the uplink call test, the preset audio played by the stereo 5 is input to the microphone of the wireless headset 2, and is transmitted to the first terminal 61 through the bluetooth connection between the wireless headset 2 and the first terminal 61, and is then transmitted to the second terminal 62 through the call connection between the first terminal 61 and the second terminal 62, and is then recorded as uplink audio data through the call recording of the second terminal 62, and then the second terminal 62 can transmit the uplink audio data to the control device 1, and the control device 1 can perform validity judgment according to the uplink audio data, so as to test whether the uplink and downlink of the wireless headset as the terminal audio are normal in the voice call scene.

In one possible embodiment, as shown in fig. 20, after a 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 in the call process as the reference audio data.
Specifically, for example, the step 101 includes: the control device 1 sends an open box pairing instruction to the wireless earphone 2, and the control device 1 sends a bluetooth device scanning instruction with a specified name to the first terminal 61, wherein the specified name is the name of the wireless earphone 2; the step 102 includes: the wireless earphone 2 enters a pairing mode in response to an open box pairing instruction, the first terminal 61 starts to scan Bluetooth equipment with a specified name in response to a Bluetooth equipment scanning instruction, and when the first terminal 61 scans the wireless earphone 2, the wireless earphone 2 is paired, and Bluetooth connection between the first terminal 61 and the wireless earphone 2 is established; step 201 comprises: the control device 1 sends a call making instruction to the first terminal 61, and the control terminal 1 sends a call answering instruction to the second terminal 62; step 202 comprises: the first terminal 61 makes a call to the second terminal 62 in response to a call making instruction, and the second terminal 62 makes a call in response to a call making instruction to establish a call connection between the first terminal 61 and the second terminal 62; step 203 comprises: after the two terminals establish a call connection, the control device 1 controls the first terminal 61 to close and open a call record so as to record the audio in the call process as reference audio data, and the control device 1 controls the sound equipment 5 to play preset audio, wherein the preset audio played by the sound equipment 5 is input through the microphone of the second terminal 62; step 204 includes: the control device 1 controls the double-channel sound card 4 to record sound collected by the artificial ear 3 into downlink audio data; after that, the first terminal 61 ends the call recording, cancels the mute, and uploads the call recording to the control device 1, wherein the call recording is the reference audio data; thereafter, step 205 includes: the control device 1 controls the second terminal 62 to close the microphone and open the call record, and the recorded audio is uplink audio data; the control device 1 controls the sound equipment 5 to play preset audio, and the preset audio played by the sound equipment 5 is input through the microphone of the wireless earphone 2; then, the second terminal 62 ends the call and uploads the recorded uplink audio data to the control device 1, that is, step 206 includes the control device 1 controlling the second terminal 62 to record the audio in the call process as the uplink audio data; the control device 1 judges the validity of the audio signal by the call recording and the audio data recorded by the two-channel sound card.
For the judgment of the validity of the audio signal, the judgment may be referred to according to the played preset audio source, for example, the preset audio is a signal with multiple frequency components and internal frequency components having a certain characteristic distribution. For the recorded uplink audio data and downlink audio data, the recorded uplink audio data and downlink audio data contain frequency characteristics of preset audio, so that signal extraction and judgment can be performed on the recorded audio data according to the frequency characteristics.
However, the downlink audio data is obtained by inputting the preset audio played by the stereo 5 into the second terminal 62, transmitting the preset audio to the first terminal 61 through the call connection, transmitting the preset audio to the wireless earphone 2 through the first terminal 61 for playing, then collecting the preset audio by the artificial ear 3, and recording the preset audio by the two-channel sound card 4, wherein the signal distortion and other problems in the communication process may be introduced in the communication transmission process of the call connection, and the signal extraction and judgment may be inaccurate due to the distortion, so that in order to solve the problem of low judgment accuracy caused thereby, the call recording on the first terminal 61 side may be introduced to obtain the reference audio data, and because the distortion influence in the communication process is also introduced in the reference audio data, the extraction and judgment of the audio signal may be corrected according to the reference audio data, so as to improve the judgment accuracy.
For similar reasons, the uplink audio data also has a problem of inaccurate signal extraction and judgment due to distortion in the communication process. To improve this problem, in one possible implementation, the uplink audio data may be obtained by recording the audio of the first terminal 61 instead, so that adverse effects caused by distortion introduced during the communication process of the terminal may be eliminated.
In one possible implementation, as shown in fig. 21 to 23, the audio test system further includes: a shielding container 7, the shielding container 7 having a cover, the shielding container 7 being for shielding a wireless signal when the cover is closed, a bluetooth connection module of one of the wireless headset 2 and the first terminal 61 being disposed inside the shielding container 7, a bluetooth connection module of the other of the wireless headset 2 and the first terminal 61 being disposed outside the shielding container 7; the shielding container 7 may further comprise a container control mechanism 8, wherein the container control mechanism 8 is used for controlling the opening and closing of the cover body, and the container control mechanism 8 is connected to the control device 1 in a communication manner; the container control mechanism 8 may realize the opening and closing control of the cover body through the push rod mechanism illustrated in fig. 7, in addition, the container control mechanism 8 may further include a driving device for driving the push rod mechanism, the driving device may include a power supply circuit and a driving circuit at the bottom layer, the driving device may be a separate electric cabinet, and the driving device is electrically connected to the push rod structure and the control device 1, that is, the container control mechanism 8 may realize the communication connection with the control device 1 through the driving device; in addition, the container control mechanism 8 may further include a limit sensor, where the limit sensor is used to sense the position of the cover and feedback control the push rod mechanism, for example, when the limit sensor senses that the cover is closed in place, the push rod mechanism is controlled to stop moving, or when the limit sensor senses that the cover is opened in place, the push rod mechanism is controlled to stop moving.
Specifically, for example, the first terminal 61 is disposed in the shielding container 7, the wireless headset 2 is disposed outside the shielding container 7, when the cover of the shielding container 7 is closed, the bluetooth connection between the wireless headset 2 and the first terminal 61 is disconnected due to the shielding effect of the shielding container 7 on the bluetooth signal, and when the cover of the shielding container 7 is opened, the bluetooth connection between the wireless headset 2 and the first terminal 61 can be maintained. The shielding container 7 may be provided with an interface through which the first terminal 61 may be connected to the outside of the shielding container 7 and thus to the control device 1 by means of a connection line, so that even if the cover of the shielding container 7 is closed, only the wireless signal is shielded and the communication connection between the control device 1 and the first terminal 61 is not adversely affected. Referring to the module division manner shown in fig. 7, the module divided from the software level by the test system further includes a shielding container control module, where an entity corresponding to the shielding container control module is a shielding container, for example, a shielding box, and the shielding box may be an electrically controlled shielding box obtained by performing electromechanical transformation on a common manual shielding box (for example, opening and closing of the shielding box is realized by controlling an electrically driven push-pull rod). The nature of the test performed by the shielding container 7 uses the shielding effect of the shielding container 7 on the bluetooth signal, so long as shielding of the bluetooth signal can be achieved. For the wireless earphone 2 and the first terminal 61, it is necessary to have bluetooth connection modules respectively to realize the bluetooth connection function, and when testing by using the bluetooth shielding effect of the shielding container 7, the two may be placed respectively inside and outside the shielding container 7 as in the above embodiment, or only one of the bluetooth connection modules may be placed inside the shielding container 7, and the other bluetooth connection module may be placed outside the shielding container 7, and the test based on the bluetooth disconnection may be performed as well.
One of the bluetooth connection module of the wireless earphone 2 (which may be a device formed by components such as an EVK carrying an audio chip and a speaker of the earphone thereof) and the bluetooth connection module of the first terminal 61 is placed in a shielding case, and the shielding case is controlled to open and close by communication between the control device 1 and a universal asynchronous receiver/Transmitter (UART) of a control board of the shielding case, so that a scene of disconnecting/recovering connection of a wireless connection between the mobile phone and the audio device is simulated. That is, by shielding the container 7, it is possible to simulate the function of the wireless headset 2 in the scenario where the bluetooth connection between the first terminal 61 and the wireless headset 2 is disconnected and the connection is restored, so that the scenario construction of disconnection and restoration is achieved without manually changing the distance between the terminal and the wireless headset when the test of the scenario is performed, thereby improving the test efficiency. For an audio test system including a shielded container, the audio test method of the embodiments of the present application may still be applied to determine audio validity.
In one possible implementation manner, the wireless earphone test system may include two shielding containers, where the two shielding containers correspond to a left ear and a right ear of the artificial ear respectively, the first terminal is disposed outside the two shielding containers, the left ear of the artificial ear and a corresponding wireless earphone of the left ear are placed in one shielding case, the right ear of the artificial ear and another corresponding wireless earphone of the right ear are placed in another shielding case, and the two shielding cases are placed in different through the left ear and the right ear respectively, so that scenes such as binaural disconnection, establishment, primary-secondary switching and the like can be simulated.

It should be noted that, the nature of the test performed by using the shielding container 7 uses the shielding effect of the shielding container 7 on the bluetooth signal, when the wireless earphone 2 is tested, since the wireless earphone 2 may not be a finished wireless earphone 2, but may be a device capable of implementing the function of the wireless earphone 2, for example, in the aforementioned test mode using the EVK instead of the chip in the finished earphone, the EVK and the earphone speaker connected thereto may be tested as the wireless earphone 2, and at this time, if the EVK has the bluetooth connection module, the EVK may be placed in the shielding container, and the left ear speaker and the right ear speaker connected to the EVK are placed outside the shielding container. The same principle applies to the first terminal, if a part of the components and the bluetooth connection module are separable, it is also possible to place only the bluetooth connection module in the shielding container and the other components in the shielding container.
In a possible embodiment, on the basis that the audio test system includes the shielding container 7, as shown in fig. 24, after the bluetooth connection is established between the wireless headset 2 and the first terminal 61, the audio test method further includes a disconnection-connection-back test, which includes: the control module 1 controls the first terminal 61 to play preset audio, wherein the preset audio can be the same as or different from other preset audio; after the control module 1 controls the first terminal 61 to play the preset audio, the control module 1 controls the cover of the shielding container 7 to be closed; after the control module 1 controls the cover of the shielding container 7 to be closed, the control module 1 controls the cover of the shielding container 7 to be opened; after the control module 1 controls the cover body of the shielding container 7 to be opened, the control device 1 controls the first terminal 61 to replay preset audio and controls the two-channel sound card 4 to record sound collected by the artificial ear 3 into the back connection audio data; the control device 1 judges the validity of the loop-back audio data so as to realize the audio judgment under the scene of breaking the loop-back, and the loop-back audio data is the test audio data. In this way, disconnection and restoration of the bluetooth connection are achieved without manually changing the distance between the first terminal 61 and the wireless headset 2, improving the test efficiency.
In one possible embodiment, the disconnection-connection-back test further comprises: after the control module 1 controls the cover of the shielding container 7 to be closed and before the control module 1 controls the cover of the shielding container 7 to be opened, the control device 1 sends a first checking instruction to the first terminal 61, and the first terminal 61 responds to the first checking instruction to check whether the Bluetooth connection with the wireless earphone 2 is disconnected or not and whether the playing of the preset audio is suspended or not; after the control module 1 controls the cover of the shielding container 7 to be opened, the control device 1 sends a second checking instruction to the first terminal 61 before the control device 1 controls the first terminal 61 to play back the preset audio, and the first terminal 61 responds to the second checking instruction to check whether the Bluetooth connection with the wireless earphone 2 is restored or not, and whether the play back of the preset audio is restored or not. Through the checking process, the disconnection and connection back conditions of the Bluetooth connection and the audio playing function can be further tested.
In one possible implementation, the wireless headset 2 includes a control module communicatively coupled to the control device 1 for simulating the headset charging case or the sensor to generate event instructions including one or any combination of the following: the earphone charging box opening instruction, the earphone charging box closing instruction, the wireless pairing instruction, the earphone wearing instruction, the earphone taking-down instruction and the earphone button clicking instruction. The control module is, for example, a module in the EVK described above. Through simulation of events, testing in different scenes can be achieved more efficiently.
In one possible implementation, the control module is further configured to obtain a log of the wireless headset, that is, capture and screening of the device log may be implemented.
In one possible implementation, as shown in fig. 25, after the bluetooth connection is established between the wireless headset 2 and the first terminal 61, the audio test method further includes a multi-service test, where the multi-service test includes: the control device 1 controls the binaural sound card 4 to start recording the sound collected by the artificial ear 3 into multi-scene audio data, and controls the first terminal 61 to play preset audio; during the process of playing the preset audio by the first terminal 61, the control terminal 1 may send a short message instruction to the second terminal 62, and the second terminal 62 sends a message to the first terminal 61 in response to the short message instruction; the first terminal 61 sounds a message alert sound in the process of playing a preset audio in response to the message sent by the second terminal 62; the first terminal 61 continuously checks the message, and when the first terminal 61 checks the message, the first terminal stops playing the preset audio; after the first terminal 61 stops playing the preset audio, sending a test completion instruction to the control apparatus 1; after the control device 1 receives the test completion instruction, the control device controls the binaural sound card 4 to finish recording the multi-scene audio data, and determines whether the recorded multi-scene audio data has preset audio and message prompt tones at the same time, so as to realize audio test under the multi-service scene, wherein the multi-scene audio data is the test audio data. The preset audio frequency is preset, so that the frequency characteristics of the preset audio frequency are different from those of the prompting voice, and in the multi-scene audio frequency data, the preset audio frequency and the prompting voice can be distinguished and identified according to the respective frequency characteristics of the preset audio frequency and the prompting voice so as to judge whether the music playing effect in the multi-service scene accords with the expectations or not. The multi-service test can judge whether the response of the first terminal accords with the expectation or not in the multi-service state (meanwhile, the music playing is doped with the short message prompt tone) by sending the short message to the first terminal by the second terminal in the music playing. According to the requirement, the method can be set in the process of playing music, if a short message is received, the playing volume of the music is temporarily reduced, meanwhile, a short message prompt tone is played, after the short message prompt tone is played, the playing volume of the music is restored, and under the scene, whether the method meets the expectation can be further judged according to multi-scene audio data.
In one possible implementation, as shown in fig. 26, the touch test includes: the control device 1 controls the first terminal 61 to add at least 2 pieces of music to the play list; the control device 1 sends a music control instruction to the wireless earphone 2 and sends a music check instruction corresponding to the music control instruction to the first terminal 61, wherein the music control instruction is a last music instruction, a next music instruction, a pause instruction or a play instruction; the first terminal 61 checks whether or not the current music is successfully controlled in response to the music check instruction. For example, touch testing includes: the control device 1 controls the first terminal to add 2 pieces of music to the play list and pause the play; the control device 1 sends a next music examination instruction to the wireless headset 2 and sends a next music examination instruction to the first terminal 61, and the first terminal 61 examines whether the current music is switched to the next music in response to the next music examination instruction; the control device 1 transmits a last music check instruction to the wireless headset 2 and transmits a last music check instruction to the first terminal 61, and the first terminal 61 checks whether the current music is switched to the last music in response to the last music check instruction; the control device 1 transmits a pause play instruction to the wireless headset 2 and transmits a pause check instruction to the first terminal 61, and the first terminal 61 checks whether the current music is in a pause state in response to the pause check instruction; the control device 1 transmits a play instruction to the wireless headset 2 and transmits a play check instruction to the first terminal 61, and the first terminal 61 checks whether the current music is in a play state in response to the play check instruction. Here, the various control instructions sent by the control device 1 to the wireless earphone 2 are realized by simulating the touch function operation of the earphone in the real scene, so as to realize the test in the touch scene. The touch test may determine whether the first terminal response meets the expectations by performing a touch operation (music playing/pausing/last song/next song) on the wireless earphone during music playing.
In one possible embodiment, as shown in fig. 27, the wear test includes: the control device 1 controls the first terminal 61 to add at least 2 pieces of music to the play list; the control device 1 sends a wearing action instruction to the wireless earphone 2, and sends a music check instruction corresponding to the wearing action instruction to the first terminal 61, wherein the wearing action instruction is an instruction of outputting a box from a left ear and inputting an ear, an instruction of outputting a box from a right ear and inputting an ear, or an instruction of outputting ears from both the left ear and the right ear; the first terminal 61 checks whether or not the current music is successfully controlled in response to the music check instruction. For example, wear testing includes: the control device 1 controls the first terminal 61 to add music and pause playing, then the control device 1 sends a left ear out-of-box in-ear instruction to the wireless earphone 2, then sends a playing check instruction to the first terminal 61, the first terminal 61 responds to the playing check instruction to check whether the current music starts playing or not, and the control device 1 judges whether the left ear is sound and the right ear is silent or not through manual ear recording; then the control device 1 sends a right ear out-of-box and in-ear instruction to the wireless earphone 2, and then judges whether the ears are voiced or not through manual ear recording; the control device 1 then sends an ear command to the wireless headset 2 from both the left and right ears and a pause check command to the first terminal 61, and the first terminal 61 checks whether the current music is in a pause state in response to the pause check command. It should be noted that the specific steps are only examples, and the specific testing procedure may be set according to the service flow and service logic of the wireless earphone itself. For example, the logic of playing music by the wireless earphone may be playing when the wireless earphone is in the ear, or may be playing only when the wireless earphone is in the ear through playing touch operation, and the corresponding testing processes under the two different logics may be different, and may be specifically set according to the needs. The wearing test can judge whether the first terminal response accords with the expected test scene by performing a simulation behavior operation (wearing/taking down) on the wireless earphone during music playing (the simulation behavior operation on the wireless earphone refers to simulating information input through a sensor by instructions, and the wearing/taking down or ear in/out actions of the earphone are simulated).
