It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

In the related technology, the time delay of the TWS earphone is mainly detected by adopting a subjective judgment mode, an objective test method aiming at wireless sound transmission/real-time listening time delay of the TWS earphone does not exist, and research, development, test and acceptance of the auxiliary function are inconvenient.

In view of this, in order to be able to objectively detect the delay of the real wireless headset, the present application provides a system, a method and a related device for testing the delay of the real wireless headset.

Fig. 1 is a schematic structural diagram of a delay testing system of a true wireless headset according to an embodiment of the present disclosure. The testing system comprises a time delay determining device 101, a sound source emitting device 102, a first audio collecting device 103, a second audio collecting device 104, a terminal device 105 and a true wireless earphone 106, wherein the distance between the first audio collecting device 103 and the sound source emitting device 102 is the same as the distance between the terminal device 105 and the sound source emitting device 102, and the testing system comprises:

the sound source emitting device 102 is configured to emit a first audio signal;

the first audio acquisition device 103 is configured to acquire the first audio signal to obtain a second audio signal and transmit the second audio signal to the delay determination device 101;

the terminal device 105 is configured to receive the first audio signal and transmit the first audio signal to the true wireless headset 106 for playing;

the second audio collecting device 104 is configured to collect a third audio signal played by the true wireless headset 106 based on the first audio signal and transmit the third audio signal to the delay determining device 101;

the delay determining means 101 is configured to determine a delay between the second audio signal and the third audio signal as the delay of the true wireless headset 106.

As shown in fig. 1, the first audio signal transmitted by the sound source transmitting device 102 reaches the first audio collecting device 103 through the propagation path S1, and the first audio signal reaches the terminal apparatus 105 through the propagation path S2. Since the propagation path S1 and the propagation path S2 are the same distance, the first audio signal transmitted by the sound source transmitting device 102 reaches the first audio collecting device 103 and the terminal apparatus 105 at the same time.

After the first audio signal is captured by the first audio capturing means 103, it is transmitted to the delay determining means 101. In the other path, the first audio signal is processed by the terminal device 105 and then sent to the real wireless earphone 106 through bluetooth, and the real wireless earphone 106 plays the first audio signal. The first audio signal played by the real wireless earphone 106 is collected by the second audio collecting device 104 and transmitted to the delay determining device 101 for delay analysis. The time delay determination device 101 performs time delay analysis on two paths of audio signals transmitted by the first audio acquisition device 103 and the second audio acquisition device 104 to obtain a transmission time difference between the two paths of audio signals, so as to obtain a transmission time delay of the true wireless headset 106.

It should be noted that the time delay determining device 101, the first audio capturing device 103, and the second audio capturing device 104 may be independent devices, or may be integrated on the same electronic device. The latency determining apparatus 101 may be an electronic device, such as a computer, a server, or other devices with processor-like functions, which are suitable for the embodiments of the present application.

Therefore, in the embodiment of the present application, the first audio collecting device 103 and the terminal device 105 are equidistant from the sound source emitting device 102, and it is ensured that the signal emitted by the sound source emitting device can reach the terminal device 105 and the first audio collecting device 103 at the same time, so that the time when the first audio collecting device 103 obtains the signal can be recorded as the time when the terminal device 105 obtains the signal, and then the time when the true wireless headset plays the signal can be recorded based on the fact that the first audio signal is played by the true wireless headset 106 and is collected by the second audio collecting device 104. As such, the delay determining means 101 may determine the delay of the true wireless headset based on the signal transmitted by the first audio capturing means 103 and the signal transmitted by the second audio capturing means 104.

Continuing with fig. 5, the first audio capture device 103 receives the first audio signal via propagation path S1, recording the time T1 at which the first audio signal was received. Likewise, the terminal device 105 receives the first audio signal transmitted by the sound source transmitting apparatus 102 through the propagation path S2, the reception time T2 thereof. Since it is difficult to record the time when the terminal device 105 receives the first audio signal, the first audio collecting means is used to collect and record the reception time. Since the propagation path S1 is equal to the propagation path S2, T1 is T2. Therefore, when the second audio capturing device 104 records the time T3 when the first audio signal is played by the true wireless earphone 106, the time T3-T1 is calculated as the time delay of the true wireless earphone.

In some embodiments, the first audio capture device 103 and the second audio capture device 104 are configured to record respective received audio signals. Therefore, the first audio capture device 103 and the second audio capture device 104 have an audio recording function, and the transmission time of the first audio signal in the first audio capture device 103 and the transmission time of the first audio signal in the second audio capture device 104 can be obtained.

In some possible embodiments, the first audio capture device 103 is a first simulated human ear, and the second audio capture device 104 is a second simulated human ear, so that the hearing of the human ear can be better simulated, and the time delay of the real wireless headset can be accurately tested.

In some possible embodiments, the terminal device 105 and the wireless headset 106 are connected via bluetooth. Other signals may interfere with the transmission of bluetooth signals. For example, when a wifi signal is strong, a packet loss may be caused in bluetooth transmission, and in the case of the packet loss, a true wireless headset may perform a packet complementing operation, so that a delay of a test may generate a slight fluctuation. Therefore, in order to improve the accuracy of the time delay test, the wifi signal strength in the test environment may be required to be smaller than the preset strength.

In some possible embodiments, the time T1 when the first audio signal is captured by the first audio capture device 103 is recorded, and the time T3 when the first audio signal is captured by the second audio capture device 104 is recorded, so that the time delay of the true wireless headset can be obtained. In the embodiment of the present application, in order to improve the accuracy of the time delay, a specified audio block for facilitating detection of a time point is added to the first audio signal transmitted by the sound source transmitting device 102. The delay determining means 101 may detect the specified audio block from the received two audio signals so as to accurately determine the delay of the true wireless headset.

In order to facilitate detection of a given audio block, the embodiment of the present application requires that the given audio block has some prominent features. For example, the specified audio block includes a specified frequency signal therein, and the signal amplitude of the specified audio block has a jump characteristic, the jump characteristic including: the signal amplitude jumps from a first amplitude to a second amplitude, and the difference between the first amplitude and the second amplitude is larger than a preset difference. According to the method and the device, the specified audio block can be well detected by taking amplitude jump and frequency difference as characteristic information, and the accuracy of detecting the specified audio block is improved.

As shown in fig. 2, a schematic diagram of a given audio block. The amplitude of the designated audio block is small at first and then jumps sharply to a larger amplitude, so that the delay determining apparatus 101 can conveniently and accurately detect the designated audio block from the signals acquired by the first audio acquiring apparatus 103 and the second audio acquiring apparatus 104, respectively.

The sound source transmitting device 102 generates the first audio signal carrying the designated audio block and transmits the first audio signal. In determining the latency, the latency determination device 101 may be implemented to:

detecting the second audio signal acquired by the first audio acquisition device 103 for the specified audio block to obtain a first audio block, and detecting the third audio signal acquired by the second audio acquisition device 104 for the specified audio block to obtain a second audio block;

then, based on the difference in transmission time of the first audio block and the second audio block, the time delay of the true wireless headset 106 is obtained.

As shown in fig. 2, the transmission time difference between the first audio block and the second audio block may be the time point of the amplitude transition position (i.e. the position indicated by the arrow in fig. 2) in fig. 2, the time point of the amplitude transition position of the first audio block is t1, and the time point of the amplitude transition position of the second audio block is t2, so that the propagation time difference can be obtained by calculating the difference between t1 and t 2.

One specifies the propagation time difference calculated by the audio block as the delay of a true wireless headset, which may produce occasional errors. Therefore, in the embodiment of the present application, a plurality of specified audio blocks may be added to the first audio signal transmitted by the sound source transmitting apparatus 101. Any number of designated audio blocks may be added. The time difference between two adjacent designated audio blocks can be the same or different, and both are applicable to the embodiment of the present application.

As shown in fig. 3, a schematic diagram of a first audio signal when transmitting a plurality of designated audio blocks. The rectangular region in fig. 3 identifies one of the designated audio blocks, and each designated audio block transmitted thereafter is the same. When a plurality of specified audio blocks are transmitted, assuming that the time delay determination apparatus 101 receives the audio signal transmitted by the first audio capture apparatus 103 through the channel 1 and receives the audio signal captured by the second audio capture apparatus 104 through the channel 2, the audio signals of the two channels have the characteristics in time as shown in fig. 4. In fig. 4, designated audio blocks detected by channel 1 in sequence are T11, T12, T13 … T1N; similarly, the designated audio blocks detected by channel 2 in sequence are T31, T32, T33 … T3N. The mean of the differences in transmission times for the same designated audio block is calculated as the time delay for the true wireless headset 106. Specifically, the time difference between the amplitude jump positions of T11 and T31 is calculated, the time difference between the amplitude jump positions of T12 and T32 is calculated, the time difference between the amplitude condition positions of T1N and T3N is calculated by analogy, N transmission time differences are obtained, and then the average value of the N transmission time differences is calculated as the time delay of the true wireless headset. Therefore, the influence caused by accidental errors can be avoided by detecting a plurality of designated audio blocks and calculating the mean value of the transmission time difference.

Of course, in some embodiments, the minimum values of the transmission time difference, such as the maximum value and the minimum value, may be eliminated and then averaged. The median of the multiple transmission time differences can also be obtained as the time delay of the true wireless earphone, and the transmission time difference corresponding to the mode of the multiple transmission time differences can also be determined as the time delay of the true wireless earphone.

As shown in fig. 4, when there are multiple specified audio blocks, the same specified audio block needs to be accurately determined in order to calculate the difference in transmission time of the same specified audio block of two channels. In the embodiment of the present application, the following may be implemented:

sequentially marking the first audio blocks detected from the second audio signal and sequentially marking the second audio blocks detected from the third audio signal; the transmission time difference is then determined for the first audio block and the second audio block having the same marker.

The way of marking may be marked as 1, 2, 3, and so on, and then the designated audio block marked the same in the two channels is the same designated audio block.

In order to obtain the transmission time of the specified audio block (i.e. the amplitude jump time point of the specified audio block in fig. 4), in this embodiment of the present application, the following processing may be performed on the audio signals acquired by the first audio acquisition device 103 and the second audio acquisition device 104, respectively: firstly, Fourier transform processing is carried out on an audio signal, a time domain is converted into a frequency domain to form a series of arrays, whether amplitude jump and a designated frequency position of a designated audio block exist or not is judged for all data, if the amplitude jump and the designated frequency position exist and are marked in the arrays, the corresponding time of a mark point is obtained to be amplitude jump time, the difference of the amplitude jump time points of the same designated audio block obtained by two channels is a transmission time difference, and all the transmission time differences are averaged to obtain a final accurate time delay result.

For the sake of understanding, the flow of the time delay measurement performed by the test system is described, and as shown in fig. 6, the flow includes the following steps:

in step 501, a sound source transmitting device transmits a signal carrying a first audio signal.

In step 502, the first audio collecting device collects the first audio signal to obtain a second audio signal, and sends the second audio signal to the delay determining device, and the terminal device receives the first audio signal and then transmits the first audio signal to the wireless headset for playing.

In step 503, the second audio collecting device collects the audio signal played by the wireless headset to obtain a third audio signal, and transmits the third audio signal to the delay determining device.

In step 504, the delay determining device receives the second audio signal collected by the first audio collecting device and the third audio signal collected by the second audio collecting device.

In step 505, the delay determining apparatus detects a specified audio block in the second audio signal, marks the amplitude jump position of the specified audio block as a first position, detects the amplitude jump position of the specified audio block as a second position in the third audio signal, and obtains a transmission time difference of the same specified audio block based on a time point corresponding to the first position and a time point corresponding to the second position.

In step 506, the time delay determination device calculates the average value of the transmission time differences of the designated audio blocks to obtain the transmission time delay of the true wireless headset.

Based on the same inventive concept, the embodiment of the application also provides a time delay testing method of the true wireless earphone.

in step 601, a second audio signal and a third audio signal are obtained, where the second audio signal is a first audio signal collected by a first signal collection device, the third audio signal is a first audio signal collected by a second audio collection device and played by a true wireless headset, the first audio signal played by the true wireless headset is transmitted to the true wireless headset by a terminal device, the first audio signal is transmitted by a sound source transmission device, and the distances from the terminal device and the first signal collection device to the sound source transmission device are the same;
