Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in other sequences than those illustrated or otherwise described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

In the following, some terms in the embodiments of the present application are explained for easy understanding by those skilled in the art.

(1) The term "plurality" in the embodiments of the present application means two or more, and other adjectives are similar thereto.

(2) "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

(3) The terminal device may refer to APP (Application) of a software class or a client. The system has a visual display interface, and can interact with a user; corresponding to the server, providing local service for clients. Applications for software classes, except some applications that only run locally, are typically installed on a common client terminal, and need to run in conjunction with a server. After the development of the internet, more commonly used application programs include, for example, short video applications, email clients when receiving email, and clients for instant messaging. For this type of application program, there is a need to have a corresponding server and service program in the network to provide a corresponding service, such as a database service, a configuration parameter service, etc., so that a specific communication connection needs to be established between the client terminal and the server terminal to ensure the normal operation of the application program.

In the related art, the subjective judgment mode is mainly adopted to detect the time delay of the TWS earphone, and no objective test method for wireless sound transmission/real-time listening time delay of the TWS earphone is available, so that the development, test and acceptance of the auxiliary function are inconvenient.

In view of this, in order to objectively detect the delay of the real wireless earphone, the embodiments of the present application provide a delay test system, a method and a related device for the real wireless earphone.

Referring to fig. 1, a schematic structural diagram of a delay test system of a real wireless earphone according to an embodiment of the present application is shown. The test 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 test system comprises the following components:

the sound source transmitting device 102 is configured to transmit 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 determining device 101;

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

The second audio acquisition device 104 is configured to acquire a third audio signal that is played by the real wireless earphone 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 a delay of the real wireless earphone 106.

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

After the first audio signal is collected by the first audio collection means 103, it is transmitted to the delay determination means 101. In the other path, the first audio signal is sent to the real wireless earphone 106 through bluetooth after being processed by the terminal device 105, and the first audio signal is played by the real wireless earphone 106. The first audio signal played by the real wireless earphone 106 is collected by the second audio collection device 104 and transmitted to the delay determination device 101 for delay analysis. The delay determining device 101 performs delay analysis on two paths of audio signals transmitted by the first audio collecting device 103 and the second audio collecting device 104 to obtain a transmission time difference of the two paths of audio signals, thereby obtaining a transmission delay of the real wireless earphone 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 delay determining device 101 may be an electronic device, such as a computer, a server, or other devices with similar processor functions, which are suitable for the embodiments of the present application.

Therefore, in the embodiment of the application, the first audio acquisition device 103 and the terminal device 105 are equidistant from the sound source emission device 102, so that the signal emitted by the sound source emission device can reach the terminal device 105 and the first audio acquisition device 103 at the same time, so that the time when the signal is obtained by the first audio acquisition device 103 as the time when the signal is obtained by the terminal device 105 can be recorded, then the first audio signal is played based on the real wireless earphone 106 and is acquired by the second audio acquisition device 104, and the time when the signal is played by the real wireless earphone can be recorded. As such, the delay determining device 101 may determine the delay of the real wireless earphone based on the signal transmitted by the first audio acquisition device 103 and the signal transmitted by the second audio acquisition device 104.

As further shown in fig. 5, the first audio acquisition device 103 receives the first audio signal through the propagation path S1, and records the time T1 at which the first audio signal is received. Similarly, the terminal device 105 receives the first audio signal transmitted by the sound source transmitting apparatus 102 through the propagation path S2, which is received at the time T2. Since it is difficult to record the time when the terminal device 105 receives the first audio signal, the first audio acquisition device is employed to acquire and record the reception time. T1=t2 since the propagation path S1 is equal to the propagation path S2. Therefore, when the second audio capturing device 104 is used to record the time T3 when the real wireless earphone 106 plays the first audio signal, the time delay of the real wireless earphone is calculated as T3-t1=t.

In some embodiments, the first audio acquisition device 103 and the second audio acquisition device 104 are configured to record respective received audio signals. Therefore, the first audio capturing device 103 and the second audio capturing device 104 have the audio recording function, so that the transmission time of the first audio signal at the first audio capturing device 103 and the transmission time of the first audio signal at the second audio capturing device 104 can be obtained.

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

In some possible implementations, the signal is transmitted by bluetooth between the terminal device 105 and the real wireless headset 106. Other signals may interfere with the transmission of bluetooth signals. For example, when the wifi signal is strong, the bluetooth transmission may be lost, and in the case of packet loss, the real wireless earphone may perform the packet padding operation, so that the delay of the test may slightly fluctuate. Therefore, in order to improve accuracy of the time delay test in the embodiment of the application, wifi signal strength in the test environment may be required to be smaller than preset strength.

In some possible embodiments, the time delay of the real wireless earphone can be obtained by recording the time T1 when the first audio acquisition device 103 acquires the first audio signal and recording the time T3 when the second audio acquisition device 104 acquires the first audio signal. In order to improve the accuracy of the time delay in the embodiment of the present application, a specified audio block that is convenient for detecting a time point is added to the first audio signal transmitted by the sound source transmitting apparatus 102. The delay determining means 101 may detect the specified audio block from the received two audio signals in order to accurately determine the delay of the real wireless headset.

To facilitate detection of a specified audio block, embodiments of the present application require that the specified audio block have some prominent features. For example, the designated audio block includes a designated frequency signal therein, and the signal amplitude of the designated audio block has a hopping characteristic, the hopping 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 embodiment of the application, the appointed audio block can be well detected by taking amplitude jump and frequency difference as characteristic information, and the accuracy of detecting the appointed audio block is improved.

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

The sound source transmitting means 102 generates said first audio signal carrying the specified audio block and transmits it out. In determining the time delay, the time delay determination means 101 may be implemented as:

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

then, based on the transmission time difference between the first audio block and the second audio block, a time delay of the real wireless earphone 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 jump position (i.e. the position indicated by the arrow in fig. 2) in fig. 2, the time point of the jump position of the first audio block is t1, and the time point of the amplitude jump position of the second audio is t2, so that the difference between t1 and t2 is calculated to obtain the propagation time difference.

A propagation time difference calculated for a given audio block is taken as a delay for a real wireless headset, possibly producing occasional errors. Accordingly, 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 specified audio blocks may be added. The time differences between two adjacent designated audio blocks may be the same or different and are suitable for the embodiments 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 is shown. The rectangular area in fig. 3 identifies one of the designated audio blocks, and each designated audio block transmitted thereafter is identical. When transmitting a plurality of specified audio blocks, assuming that the delay determining means 101 receives the audio signal transmitted by the first audio acquisition means 103 through the channel 1 and the audio signal acquired by the second audio acquisition means 104 through the channel 2, the audio signals of the two channels have characteristics in time as shown in fig. 4. In fig. 4, the designated audio blocks sequentially detected by channel 1 are T11, T12, T13 … T1N; similarly, the designated audio blocks sequentially detected by channel 2 are T31, T32, T33 … T3N. The average of the transmission time differences for the same specified audio block is calculated as the delay of the real wireless headset 106. Specifically, the time difference of the amplitude jump positions of T11 and T31 is calculated, the time difference of the amplitude jump positions of T12 and T32 is calculated, the time difference of the amplitude condition positions of T1N and T3N is calculated by such a push, 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 real wireless earphone. Thus, the influence of accidental errors can be avoided by detecting a plurality of designated audio blocks and averaging the transmission time differences.

Of course, in some embodiments, the transmission time difference may be averaged after removing its maximum, e.g., maximum, and minimum. The median of the plurality of transmission time differences can be obtained as the time delay of the real wireless earphone, and the transmission time difference corresponding to the mode of the plurality of transmission time differences can be determined as the time delay of the real wireless earphone.

As shown in fig. 4, when there are a plurality of specified audio blocks, it is necessary to accurately determine the same specified audio block in order to calculate the transmission time difference of the same specified audio block of two channels. In the embodiment of the application, the method can be implemented as follows:

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 label.

The manner of marking can be marked as 1, 2, 3, and so on, and then the same specified audio block is marked in the two channels.

In order to obtain the transmission time of the designated audio block (i.e., the amplitude jump time point of the designated audio block in fig. 4), in this embodiment of the present application, the following processing may be performed on the audio signals collected by each of the first audio collection device 103 and the second audio collection device 104: firstly, carrying out Fourier transform processing on an audio signal, converting a time domain into a frequency domain into a series of arrays, judging whether amplitude jump and a designated frequency position of a designated audio block exist for all data, if so, marking the amplitude jump and the designated frequency position in the array, obtaining the corresponding time of a marking point, namely the amplitude jump time, and taking the difference of the amplitude jump time points of the same designated audio block obtained by two channels, namely a transmission time difference, and averaging all the transmission time differences to obtain a final required accurate time delay result.

For easy understanding, a flow of time delay measurement of the present test system is described, and the flow is shown in fig. 6, and includes the following steps:

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

In step 502, the first audio acquisition device acquires the first audio signal, then obtains a second audio signal, sends the second audio signal to the time delay determination device, and the terminal device receives the first audio signal and sends the first audio signal to the real wireless earphone for playing through bluetooth.

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

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

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

In step 506, the delay determining device calculates the average value of the transmission time differences of each designated audio block to obtain the transmission delay of the real wireless earphone.

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