It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of a signal output method according to an embodiment of the present invention, where the signal output method according to the embodiment is suitable for a situation where any kind of playback terminal needs to synchronously output multiple signals. The method can be executed by the signal output device provided by the embodiment of the present invention, the device can be implemented by software and/or hardware, and is integrated in a playing terminal for executing the method, and the playing terminal for executing the method in this embodiment may be any intelligent terminal such as a tablet computer, a notebook, a desktop, and an MP 4. Referring to fig. 1, the method specifically includes the following steps:

s110, the playing terminal receives the playing instruction.

Specifically, in order to evaluate whether the synchronization performance of the audio system in the TWS headset meets the requirement in the development and production processes of the TWS headset, it is required to test whether the audio data of the TWS headset and the playing terminal are played synchronously, and whether the audio data of the left channel and the audio data of the right channel in the TWS headset are played synchronously. The TWS headset is connected to the play terminal, and during testing, the play terminal first needs to receive a play instruction, and the play instruction controls the play terminal to start playing audio data or video data. Furthermore, when testing the synchronization performance of the TWS headset, the TWS headset is first connected to the playing terminal and the testing device, and after the connection is successful, preferably, the testing device sends a test instruction to the TWS headset to be tested, after receiving the test instruction, the TWS headset sends a playing instruction to the playing terminal, the playing terminal receives the playing instruction and starts playing the audio data or the video data, and the testing device receives a signal output by the playing terminal and starts testing the synchronization performance of the TWS headset.

S120, the playing terminal plays the first audio data according to the playing instruction, acquires a first audio signal corresponding to the first audio data, and controls the brightness of the screen to change along with the change of the amplitude of the first audio signal.

Specifically, after receiving the play instruction, the play terminal starts to play first audio data that is pre-stored in the play terminal and is used for testing the performance of the TWS headset, where the first audio data is digitized sound data, that is, digitized audio data obtained by performing analog-to-digital conversion on a continuous analog audio signal at a certain sampling frequency. When the playing terminal plays the first audio data, it is necessary to perform digital-to-analog conversion on the first audio data to convert the first audio data into a corresponding analog audio signal, which is the corresponding first audio signal. Further, in order to test whether there is a delay between the TWS headset and the cast terminal, the delay may be determined according to the screen brightness change time and the amplitude change time of the audio signal by synchronously changing the screen brightness of the cast terminal when the amplitude of the audio signal changes. Preferably, an application software is installed on the playing terminal, and the application software is specially used for playing corresponding audio data or video data as required when the synchronization performance of the TWS headset is tested, and controlling the brightness to synchronously change along with the amplitude of the audio signal.

Further, after receiving the play instruction, the play terminal indicates that the TWS headset has been successfully connected to the play terminal and the test device, and the test device starts to test the synchronization performance of the TWS headset, and at this time, the play terminal needs to play audio data and output the audio data through the TWS headset. Optionally, the playing terminal plays the first audio data stored in advance through the installed application software according to the playing instruction, obtains the first audio signal converted correspondingly when the first audio data is played, and controls the screen brightness to change along with the change of the amplitude of the first audio signal by changing the brightness of the backlight board of the screen of the playing terminal, so that the testing device tests the synchronization performance of the TWS headset.

S130, the playing terminal receives the optical signal corresponding to the brightness of the screen through the photosensitive device installed on the screen and outputs the electric signal corresponding to the optical signal.

Specifically, after the first audio data is played by the play terminal, in order to test the synchronization performance between the play terminal and the TWS headset, an optical signal corresponding to the brightness of the screen needs to be received, and a corresponding electrical signal needs to be output, so as to detect the time when the brightness of the screen changes correspondingly with the amplitude of the first audio signal. Further, a light sensing device is installed on the screen of the playing terminal to receive the light signal corresponding to the brightness of the screen and output the electric signal corresponding to the light signal. The photosensitive device is an electronic device sensitive to a light source, can realize a photoelectric conversion function, and can include a photoresistor, a photodiode, a color sensor and the like.

S140, the playing terminal inputs the first audio signal to the left channel and the right channel of the real wireless stereo TWS earphone.

Specifically, after playing the first audio data or the video data and the second audio data corresponding to the video data, the playing terminal needs to output the first audio signal or the second audio signal that is obtained correspondingly. In order to test the synchronization performance of the left channel and the right channel in the TWS earphone, the playing terminal respectively inputs the acquired first audio signal or second audio signal into the left channel and the right channel of the TWS earphone which is in wireless connection with the playing terminal in a wireless transmission mode.

Further, fig. 1B is a flowchart of another signal output method according to an embodiment of the present invention, and the another signal output method provided in this embodiment is also applicable to any situation where a plurality of signals need to be synchronously output by a playback terminal, and forms two different technical solutions with the signal output method. Referring to fig. 1B, the method specifically includes the following steps:

s101, the playing terminal receives a playing instruction.

S102, the playing terminal plays the video data and the second audio data corresponding to the video data according to the playing instruction, acquires a second audio signal corresponding to the second audio data and an image corresponding to the video data, and controls the brightness or color of the image to change along with the change of the amplitude of the second audio signal.

Specifically, after receiving the play instruction, the play terminal may also play video data pre-stored in the play terminal and second audio data corresponding to the video data, and output an image corresponding to the video data and a second audio signal converted corresponding to the second audio data by obtaining the image corresponding to the video data, where the image corresponding to the video data may be a picture, a video picture, or the like. Further, in order to obtain video data and audio data which change synchronously, when the amplitude of the audio signal changes, the brightness or color of the image corresponding to the video data of the playing terminal changes synchronously, for example, the brightness of the image can be realized by changing the image pictures with different brightness, for example, when the brightness of the image is controlled to be changed from brightness to darkness, the image brightness can be realized by changing the video pictures at night to the video pictures at day; the color of the image corresponding to the video data may also be synchronously changed when the amplitude of the audio signal changes, for example, by replacing a white picture corresponding to the video data with a black picture, or by directly modifying the RGB values in the RGB color standard of the display of the picture corresponding to the video data to correspondingly modify the color of the picture, and determining whether to delay the change according to the brightness or color change time of the image corresponding to the video data and the amplitude change time of the corresponding second audio signal. Preferably, an application software is installed on the playing terminal, the application software is specially used for testing the synchronization performance of the TWS headset, playing the corresponding video data and the corresponding second audio data according to the requirement during the test, and controlling the image brightness or color corresponding to the video data to synchronously change with the amplitude of the second audio signal corresponding to the second audio data.

Further, when the testing device tests the synchronization performance of the TWS headset, the playing terminal plays the pre-stored video data and the second audio data corresponding to the video data through the installed application software according to the playing instruction, acquires the second audio signal converted corresponding to the second audio data and the image corresponding to the video data, and controls the playing terminal to play the picture or video picture corresponding to the video data with different picture brightness or color according to the amplitude change of the second audio signal, so that the picture brightness or color changes along with the change of the amplitude of the second audio signal, and the synchronization performance of the TWS headset is tested.

S103, the playing terminal receives an optical signal corresponding to the brightness or color of the image through a photosensitive device installed on the screen and outputs an electric signal corresponding to the optical signal.

Specifically, after the video data and the second audio data corresponding to the video data are played by the play terminal, in order to test the synchronization performance between the play terminal and the TWS headset, it is necessary to receive an optical signal corresponding to the brightness or color of the image and output a corresponding electrical signal, so as to detect the time when the brightness or color of the image changes correspondingly with the amplitude of the second audio signal. Further, a light sensing device is installed on the screen of the play terminal to receive an optical signal corresponding to the brightness or color of an image and output an electrical signal corresponding to the optical signal. The photosensitive device is an electronic device sensitive to a light source, can realize a photoelectric conversion function, and can include a photoresistor, a photodiode, a color sensor and the like.

And S104, the playing terminal inputs the second audio signal into a left channel and a right channel of the real wireless stereo TWS earphone.

Specifically, after playing the video data and the second audio data corresponding to the video data, the playing terminal needs to output the second audio signal that is obtained correspondingly. In order to test the synchronization performance of the left channel and the right channel in the TWS earphone, the playing terminal respectively inputs the acquired second audio signal into the left channel and the right channel of the TWS earphone which is in wireless connection with the playing terminal in a wireless transmission mode.

According to the technical scheme of the embodiment, the synchronous output of the electric signal corresponding to the optical signal and the audio signal is realized by controlling the synchronous change of the brightness of the screen of the playing terminal or the brightness or the color of the image corresponding to the video and the amplitude of the audio signal, so that the test signal is provided for testing the earphone, and the complexity of obtaining the test signal is simplified.

On the basis of the above technical solution, further, the playing terminal plays the first audio data according to the playing instruction, and acquires a first audio signal corresponding to the first audio data, including:

the playing terminal acquires at least two groups of first audio data with the same amplitude data and different frequency data, and plays the at least two groups of first audio data according to the playing instruction.

Specifically, in order to test the playing quality of the left and right channels of the TWS headphone and the difference in playing performance between the left and right channels, the frequency response characteristics of the left and right channels need to be measured. Before the playing terminal plays the first audio signal, in order to measure the frequency response characteristics of the left and right channels, at least two sets of first audio data with the same amplitude data and different frequency data need to be acquired, and the acquired at least two sets of first audio data are played according to the playing instruction. The frequency response of the TWS headphone refers to a phenomenon that when an audio signal output at a constant voltage is connected to the TWS headphone, sound pressure generated by the headphone is increased or attenuated according to a change in frequency, and a phase of the sound pressure is changed according to the frequency, that is, a frequency range within which the TWS headphone can reproduce audio data played by a playing terminal within an amplitude allowable range, and a change amount of the signal within the frequency range. And playing the audio data with the same amplitude and different frequencies, and judging the playing performance of the TWS earphone through the amplitude change of the correspondingly output signal.

The playing terminal acquires at least two first audio signals corresponding to at least two groups of first audio data.

Specifically, when the playing terminal plays the at least two sets of first audio data according to the playing instruction, at least two first audio signals corresponding to the at least two sets of first audio data need to be acquired, and then the at least two sets of first audio signals are played.

Correspondingly, the playing terminal plays the video data and the second audio data corresponding to the video data according to the playing instruction, and acquires the second audio signal corresponding to the second audio data and the image corresponding to the video data, including:

the playing terminal acquires the video data and at least two groups of second audio data which are respectively corresponding to the video data, have the same amplitude data and different frequency data, and plays the video data and at least two groups of second audio data respectively corresponding to the video data according to the playing instruction.

Specifically, when video data and second audio data corresponding to the video data are acquired, in order to test the playing quality of the left and right channels of the TWS headphone and the difference in playing performance between the left and right channels, the frequency response characteristics of the left and right channels are measured. Before the playing terminal plays the second audio signal, in order to measure the frequency response characteristics of the left and right channels, it is necessary to acquire the video data and at least two sets of second audio data having the same amplitude data and different frequency data respectively corresponding to the video data, and play the acquired video data and at least two sets of second audio data respectively corresponding to the video data according to the playing instruction. And playing a plurality of groups of audio data with the same amplitude and different frequencies, and judging the playing performance of the TWS earphone through the corresponding output frequency response characteristics.

The playing terminal acquires at least two second audio signals respectively corresponding to the at least two groups of second audio data and acquires images corresponding to the video data.

Specifically, when the playing terminal plays the video data and at least two sets of second audio data corresponding to the video data respectively according to the playing instruction, at least two second audio signals corresponding to the at least two sets of second audio data need to be acquired, and an image corresponding to the video data is acquired and then played.

Example two

Fig. 2 is a flowchart of a TWS headset testing method according to a second embodiment of the present invention, where the TWS headset testing method according to the second embodiment is suitable for testing synchronization performance of any TWS headset. The method may be performed by a TWS headset testing apparatus provided by an embodiment of the present invention, which may be implemented by means of software and/or hardware and integrated in a testing device performing the method. Referring to fig. 2, the method specifically includes the following steps:

s210, the test equipment acquires the electric signal output by the photosensitive device on the playing terminal and the audio signal to be tested output by the TWS earphone.

Specifically, when the user tests the performance of the TWS headset through the testing device, the testing principle is as shown in fig. 3, and the testing device may include an indicator, a bluetooth antenna, a processor, a headset testing point, and the like, the photosensitive device and the headset testing point are disposed on the playing terminal, and the indicator, the bluetooth antenna, and the processor are disposed in the testing device. The indicator can comprise a display screen for reading parameters and indexes, and/or an indicator light for indicating whether the test is passed or not; the Bluetooth antenna adopts a Bluetooth Low Energy (BLE) technology and is used for reporting test data; the test module can adopt a Bluetooth low-energy consumption chip nRF52832 to test data output by the TWS earphone; the two earphone test points are respectively used for connecting a left channel and a right channel of a TWS earphone to be tested, can be directly connected with audio output systems of the left channel and the right channel of the TWS earphone to directly acquire output analog audio signals, and can also be connected with a microphone through a clamp, the microphone is aligned to a left channel earphone and a right channel earphone of the TWS earphone, and the analog audio signals output by the left channel and the right channel of the TWS earphone are acquired through pickup. Further, in order to test whether the TWS headset and the playback terminal are synchronized, the testing device needs to acquire a signal output from the playback terminal. Because the brightness of the screen is controlled to change along with the change of the amplitude of the first audio signal when the playing terminal plays the first audio data, or the brightness or the color of the image corresponding to the video data is controlled to change along with the change of the amplitude of the second audio signal when the playing terminal plays the video data and the second audio signal corresponding to the video data, and the playing terminal inputs the first audio signal or the second audio signal to the left channel and the right channel of the TWS earphone respectively in a wireless transmission mode, the photosensitive device installed on the screen of the playing terminal receives the brightness of the screen changed corresponding to the first audio signal or the optical signal corresponding to the brightness or the color of the image changed corresponding to the second audio signal, the photosensitive device correspondingly converts the optical signal into an electrical signal to be output, and the TWS earphone correspondingly converts the optical signal into the electrical signal to be output according to the received first audio signal or the received second audio signal, and correspondingly outputting a left channel audio signal at the left channel, and correspondingly outputting a right channel audio signal at the right channel. In order to test whether the TWS earphone and the playing terminal are synchronous or not, the testing device needs to acquire an electric signal output by the photosensitive device and a to-be-tested audio signal output by the TWS earphone, and judge the electric signal and the to-be-tested audio signal, wherein the to-be-tested audio signal is any one of a left channel audio signal output by a left channel of the TWS earphone and a right channel audio signal output by a right channel of the TWS earphone.

Further, in order to test whether the TWS earphone and the playback terminal are synchronized, the test device further needs to obtain an electrical signal output by a light sensing device on the playback terminal and a to-be-tested audio signal output by the TWS earphone, where the electrical signal corresponds to a light signal received by the light sensing device, the light signal corresponds to brightness of a screen of the playback terminal, or the light signal corresponds to brightness or color of an image displayed in the playback terminal, and the to-be-tested audio signal is a left channel audio signal output by a left channel of the TWS earphone or a right channel audio signal output by a right channel.

S220, the test equipment determines the time delay value of the electric signal and the audio signal to be tested according to the amplitude jump time of the detected electric signal and the amplitude jump time of the audio signal to be tested.

Specifically, after the test equipment acquires the electrical signal output by the light sensing device on the play terminal, in order to test the synchronization performance of the TWS headset, the play terminal may play the first audio data or the second audio data, acquire the corresponding first audio signal or the second audio signal, and output the changed brightness of the screen synchronously by changing the amplitude of the first audio signal, or output the changed optical signal corresponding to the brightness or color of the image synchronously by changing the amplitude of the second audio signal, and output the changed audio signal to be tested. Furthermore, the amplitude of the electrical signal corresponding to the optical signal is changed by detecting the amplitude jump time of the electrical signal and the amplitude jump time of the audio signal to be tested output by the TWS headset, that is, the time of the change of the brightness or color state of the screen or the image and the time of the change of the state of the audio signal to be tested, the test equipment determines the time delay value of the electrical signal and the audio signal to be tested, so as to judge the synchronization performance between the TWS headset and the playing terminal.

And S230, the testing equipment determines whether the TWS earphone and the playing terminal are synchronous or not based on the time delay values of the electric signal and the audio signal to be tested.

Specifically, the test device determines a time delay value of the electrical signal and the audio signal to be tested, and then determines whether the time delay value is within a preset time range, and if the time delay value is within the preset time range, the test device determines that the TWS headset and the play terminal are played synchronously.

According to the technical scheme of the embodiment, the amplitude jump time of the electric signal output by the photosensitive device and the audio signal to be tested output by the TWS earphone is calculated, so that the synchronization performance of the TWS earphone and the playing terminal can be tested, the complexity of testing equipment is simplified, the testing cost is reduced, a basis is provided for developing and debugging the TWS earphone, and the testing efficiency of the TWS earphone is improved.

EXAMPLE III

Fig. 4 is a flowchart of a TWS headset testing method according to a third embodiment of the present invention. The embodiment is optimized on the basis of the embodiment. Referring to fig. 4, the method of this embodiment specifically includes:

s310, the testing equipment acquires a left channel audio signal and a right channel audio signal which are respectively output by a left channel and a right channel of the TWS earphone.

Specifically, the test device can only determine whether the TWS headset and the play terminal are synchronized according to the amplitude transition time of the acquired electrical signal and the amplitude transition time of the audio signal to be tested, and also needs to test whether the left channel and the right channel of the TWS headset are synchronized. After a first audio signal or a second audio signal is input into a left channel and a right channel of a TWS earphone to be tested through a playing terminal by a wireless transmission technology, the first audio signal or the second audio signal is correspondingly output through the left channel and the right channel of the TWS earphone, a testing device can be directly connected with audio output systems of the left channel and the right channel of the TWS earphone or can be connected with a microphone through a clamp, the microphone aims at a left channel earphone and a right channel earphone of the TWS earphone, and the left channel audio signal and the right channel audio signal which are correspondingly output by the left channel and the right channel of the TWS earphone are obtained.

S320, the test equipment determines the time delay value of the left channel audio signal and the right channel audio signal according to the detected amplitude jump time of the left channel audio signal and the right channel audio signal, and/or; the test equipment acquires the phase difference of the left channel audio signal and the right channel audio signal.

Specifically, after the testing device obtains the left channel audio signal and the right channel audio signal respectively output by the left channel and the right channel of the TWS headset, in order to test the synchronous playing performance of the left channel and the right channel of the TWS headset, it is necessary to detect the states of the first audio signal or the second audio signal input into the TWS headset, which correspond to the left channel audio signal and the right channel audio signal respectively output by the left channel and the right channel. Furthermore, the playing terminal plays the first audio data or the second audio data, and acquires the corresponding first audio signal or the second audio signal, and can correspondingly output the changed left channel audio signal and the right channel audio signal by changing the amplitude of the audio signal, the testing device can detect the corresponding amplitude jump time of the left channel audio signal and the right channel audio signal, that is, the time of the state change of the audio signal, and determine the time delay value of the left channel audio signal and the right channel audio signal according to the amplitude jump time of the left channel audio signal and the right channel audio signal, thereby judging whether the playing of the left channel and the right channel of the TWS headset is synchronous. Since the amplitude change of the audio signal has a certain rule, if the frequency of the audio signal is very small, the amplitude change of the audio signal within a certain delay time is not obvious, so that the phase difference between the left channel audio signal and the right channel audio signal can be obtained to judge whether the playing of the left channel and the right channel of the TWS earphone is synchronous or not. The phase represents the position relation of a signal waveform cyclic change, the phase difference represents the difference value of the output audio signal position change of the left channel and the right channel caused by time delay, and the audio signal has a certain period. The phase difference can be directly calculated by a Fast algorithm of discrete Fourier transform, that is, Fast Fourier Transform (FFT). Preferably, the synchronization performance of the left channel and the right channel of the TWS headphone can be determined simultaneously by combining the amplitude jump time and the phase difference of the left channel audio signal and the right channel audio signal.

Further, in order to determine whether the playing of the left channel and the right channel of the TWS headset is synchronous, the testing device may detect corresponding amplitude jump times of the acquired left channel audio signal and right channel audio signal, and determine a time delay value of the left channel audio signal and the right channel audio signal according to the detected amplitude jump times of the left channel audio signal and the right channel audio signal; in addition, the testing device can also directly calculate and acquire the phase difference between the left channel audio signal and the right channel audio signal through an FFT algorithm, determine whether the playing between the left channel and the right channel has time delay or not, or judge whether the time delay exists between the left channel and the right channel through the combination of the left channel and the right channel.

S330, the testing equipment determines whether the TWS headset left channel and the TWS headset right channel are synchronous or not based on the time delay value and/or the phase difference.

Specifically, after calculating a time delay value and/or a phase difference of the acquired left channel audio signal and right channel audio signal, the testing device determines whether the left channel and right channel of the TWS headset are synchronous or not based on the time delay value and/or phase difference.
