It should also be understood that in some embodiments, the above devices are not portable communication devices, but desktop computers having a touch-sensitive surface (e.g., a touch screen display and / or a touchpad).

[0043] In addition, in the description of the present application, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0044] The following describes a headphone testing method provided by an embodiment of the present application. Please refer to the attached Figure 1 In the headphone testing method of the first embodiment of the present application, it is applied to a true wireless headphone system. The true wireless headphone system includes: a charging case and the headphone under test. Among them, the charging case is provided with a cavity for accommodating the headphone under test, and an interface for connecting to the headphone under test is provided in the cavity. The headphone under test is provided with a sound-emitting device and a sound-receiving device.

[0045] Among them, the headphone under test can be a true wireless headphone, such as a Bluetooth headphone. Specifically, it can be the left headphone or the right headphone of a Bluetooth headphone. And, a sound-emitting device and a sound-receiving device are configured in the headphone under test. The sound-emitting device can specifically be a speaker, and the sound-receiving device can be a microphone.

[0046] Specifically, the cavity of the charging case contains at least one charging bin. During daily use after the headphone is produced, it will be placed in this charging bin for charging, thereby improving the battery life of the headphone. At the same time, the charging case can play a role in facilitating carrying and is often used in combination with the headphone.

[0047] Generally speaking, a headphone includes two headphones, namely the left headphone and the right headphone. Correspondingly, there are also two charging positions in the cavity of the charging case, namely the left charging position and the right charging position. For example, when the headphone under test is the left headphone, the headphone under test is located in the left charging position of the charging case. When the headphone under test is the right headphone, the headphone under test is located in the right charging position of the charging case.

[0048] In addition, an interface for connecting to the headphone under test is provided in the cavity. The interface can be a communication interface and / or a charging interface. When the interface is a communication interface, the charging case has a data communication function. The specific communication method can be Universal Serial Bus (USB) communication, Bluetooth communication, wifi communication, or broadband communication, etc. Or, the communication interface can also be a contact, and the charging case can charge and transmit data through this contact. The data transmission can be, for example: receiving a test instruction. When the interface is a charging interface, the headphone can be charged through this charging interface.

[0049] Among them, the headphone testing method includes:

[0050] Step S11: Trigger the sound-emitting device to output a sound signal and trigger the sound-receiving device to receive sound.

[0051] The applicable scenario of this embodiment is the self-test situation of the same headphone, that is, the sound-emitting device of the headphone under test emits a sound signal, and the sound-receiving device of the headphone under test receives the sound signal, and tests are performed based on the obtained sound signal.

[0052] Specifically, the headphone testing device or other communication device in this embodiment establishes a communication connection with the charging case. This communication connection can be a USB communication connection, a Bluetooth communication connection, a wifi communication connection, a broadband communication connection, etc. After establishing the communication connection, the headphone testing device or other communication device sends a test instruction to the charging case, and the charging case sends the test instruction to the headphone under test. The sound-emitting device in the headphone under test emits a sound signal under the trigger of the test instruction, and the sound-receiving device in the headphone under test receives this sound signal under the trigger of the test instruction. Among them, the other communication device can be a computer, a smart terminal (for example, a smart phone or a wearable device).

[0053] Step S12: Obtain the sound signal received by the sound-receiving device.

[0054] In the embodiment of the present application, the sound signal received by the sound-receiving device can be obtained by an active acquisition method. After the above-mentioned sound-emitting device finishes emitting the sound signal, the sound signal received by the sound-receiving device is obtained from the above-mentioned headphone under test; alternatively, the sound signal received by the sound-receiving device can also be obtained by a passive acquisition method, that is, after the above-mentioned sound-emitting device finishes emitting the sound signal, the sound signal received by the sound-receiving device is actively uploaded from the above-mentioned headphone under test so that the relevant device (such as the headphone testing device) in the embodiment of the present application can obtain the sound signal received by the sound-receiving device.

[0055] Among them, the sound signal output by the sound-emitting device in the embodiment of the present application can be a pre-set sound signal such as speech, animal calls, or music.

[0056] Step S13: Test the headphone under test based on the obtained sound signal.

[0057] In an ideal state, the sound signal received by the above-mentioned sound-receiving device is basically the same as the sound signal output by the sound-emitting device. However, affected by the quality of the sound-receiving device of the headphone under test itself, the sound signal received by the sound-receiving device in this embodiment may not be the same as the sound signal output by the sound-emitting device. Therefore, in step S13, the headphone under test can be tested based on the obtained sound signal.

[0058] Specifically, an acoustic performance curve of the headphone under test can be generated according to the obtained sound signal, and the acoustic performance of the headphone under test can be determined based on this acoustic performance curve and a preset standard acoustic performance curve.

[0059] In an application scenario, only the sound-emitting device or the sound-receiving device of the earphone under test is tested. Specifically, when it is known that the sound-receiving device of the earphone under test is normal, when testing the sound-emitting device of the earphone under test, the acoustic performance curve of the sound-emitting device can be determined according to the sound signal received by the sound-receiving device, and then the acoustic performance of the sound-emitting device can be determined according to the acoustic performance curve and the preset standard acoustic performance curve. When it is known that the sound-emitting device of the earphone under test is normal, when testing the sound-receiving device of the earphone under test, the acoustic performance curve of the sound-receiving device can be determined according to the sound signal received by the sound-receiving device, and then the acoustic performance of the sound-emitting device can be determined according to the acoustic performance curve and the preset standard acoustic performance curve.

[0060] Taking the example of testing the sound-emitting device of the earphone under test when it is known that the sound-receiving device of the earphone under test is normal, the sound-emitting device of the earphone under test emits a sound signal, the sound-receiving device of the earphone under test receives the sound signal emitted by the sound-emitting device of the earphone under test, and an acoustic performance curve related to the frequency response and distortion of the above-mentioned sound-emitting device is obtained based on the received sound signal. The acoustic performance curve is compared with the pre-stored standard acoustic performance curve. If the matching degree of the two curves exceeds the preset matching degree (for example, 98%), it is determined that the sound-emitting device of the earphone under test is normal, otherwise it is determined that the sound-emitting device of the earphone under test is abnormal. Among them, the standard acoustic performance curve is the acoustic performance curve obtained by the standard sound-emitting device (i.e., the sound-emitting device with normal acoustic performance) of the earphone under test emitting sound and the standard sound-receiving device (i.e., the sound-receiving device with normal acoustic performance) of the earphone under test receiving sound.

[0061] The specific test standard can be to first test the earphone under test with normal acoustic performance (i.e., both the sound-emitting device and the sound-receiving device are normal). The sound-emitting device emits a preset sound signal, that is, a preset sound at a preset volume. The acoustic performance curve related to the frequency response and distortion obtained according to the sound signal received by the sound-receiving device is used as the standard acoustic performance curve. When testing, the sound-emitting device of the earphone under test also emits the same sound signal, and the acoustic performance curve related to the frequency response and distortion obtained according to the sound signal received by the sound-receiving device is compared with the above-obtained standard acoustic performance curve for a control test.

[0062] When testing the sound-receiving device of the earphone, a similar method is adopted and will not be elaborated here.

[0063] In another application scenario, the acoustic performances of the sound-emitting device and the sound-receiving device of the earphone under test are tested simultaneously. At this time, an acoustic performance curve related to the frequency response and distortion can be obtained according to the acquired sound signal. The acoustic performance curve is compared with the pre-stored standard acoustic performance curve. If the matching degree of the two curves exceeds the preset matching degree (for example, 98%), it is determined that both the sound-emitting device and the sound-receiving device of the earphone under test are normal, otherwise it is determined that the acoustic performance of the earphone under test is abnormal.

[0064] When it is determined that the acoustic performance of the earphone under test is abnormal, further tests are required to determine whether the sound-emitting device of the earphone under test is abnormal, whether the sound-receiving device of the earphone under test is abnormal, or both are abnormal. Specifically, the solution in this application can be used to separately test the sound-emitting device or the sound-receiving device of the earphone under test, or the earphone test equipment in the prior art can be used to separately test the sound-emitting device or the sound-receiving device of the earphone under test.

[0065] In an alternative embodiment, in order to exclude the abnormal test results caused by the abnormal sound-emitting device of the first earphone, the sound-emitting device of the first earphone can be separately tested before triggering the sound-emitting device of the first earphone to output a sound signal. Or after the test is abnormal, the sound-emitting device of the first earphone is separately tested. Specifically, the solution in this application can be used to separately test the sound-emitting device of the first earphone, or the earphone test equipment in the prior art can be used to separately test the sound-emitting device of the first earphone.

[0066] In the earphone test method provided in the first embodiment, the earphone under test is placed in the charging case, and the closed space of the charging case is used to prevent the sound from spreading, so that the earphone under test can emit and receive sounds by itself without the need to use a test device to emit sounds, saving the test cost. And directly testing in the charging case without taking out the earphone from the charging case further improves the test efficiency.

[0067] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0068] In an alternative embodiment, inside the charging case, the sound-emitting device and the sound-receiving device are in a communicating cavity.

[0069] Moreover, a gap is provided at the relative position between the output side of the sound-emitting device and the input side of the sound-receiving device, so that the above sound signal can be transmitted to the sound-receiving device through the gap.

[0070] In the above alternative embodiment, there will be certain gaps inside the charging case in addition to the earphone under test, thus forming a cavity where the sound signal can propagate, so that the sound-receiving device of the same earphone can better detect the sound signal emitted by the sound-emitting device.

[0071] The following describes another earphone test method provided by the embodiments of the present application. Please refer to the attached Figure 2A, the headphone testing method in the second embodiment of the present application is applied to a true wireless headphone system, which includes: a charging case, a first headphone, and a second headphone. The charging case is provided with a cavity for accommodating the first headphone and the second headphone, and an interface for connecting to each headphone is provided in the cavity. Each headphone is provided with a sound-emitting device and a sound-receiving device.

[0072] Among them, both the first headphone and the second headphone can be used as the headphones to be tested. In this embodiment, the cavity of the charging case includes at least two charging positions. The first headphone is located in the first charging position of the charging case, and the second headphone is located in the second charging position of the charging case.

[0073] For a detailed introduction to each device in the true wireless headphone system, refer to the above-mentioned first embodiment, which will not be elaborated here.

[0074] Among them, the headphone testing method includes:

[0075] Step S21: Trigger the sound-emitting device of the first headphone to output a sound signal, and trigger the sound-receiving device of the second headphone to receive the sound.

[0076] The applicable scenario of this embodiment is the case where the two headphones are tested against each other, that is, the sound-emitting device of the first headphone emits a sound, and the sound-receiving device of the second headphone receives the sound signal.

[0077] Specifically, the headphone testing device or other communication device in this embodiment establishes a communication connection with the charging case. This communication connection can be a USB communication connection, a Bluetooth communication connection, a wifi communication connection, or a broadband communication connection, etc. After establishing the communication connection, the headphone testing device or other communication device sends a test instruction to the charging case, and the charging case sends the test instruction to the first headphone. The sound-emitting device in the first headphone emits a sound signal under the trigger of the test instruction, and the sound-receiving device in the second headphone receives the sound signal under the trigger of the test instruction. Among them, the other communication device can be a computer, a smart terminal (for example, a smart phone or a wearable device).

[0078] Step S22: Obtain the sound signal received by the sound-receiving device of the second headphone.

[0079] In the embodiment of the present application, the sound signal received by the sound-receiving device of the second headphone can be obtained by an active acquisition method. After the sound-emitting device of the first headphone ends the sound signal, the sound signal received by the sound-receiving device is obtained from the second headphone; alternatively, a passive acquisition method can also be used to obtain the sound signal received by the sound-receiving device of the second headphone, that is, after the sound-emitting device of the first headphone ends the sound signal, the sound signal received by the sound-receiving device is actively uploaded from the second headphone so that the relevant device (such as the headphone testing device) in the embodiment of the present application can obtain the sound signal received by the sound-receiving device of the second headphone.

[0080] Among them, the sound signal output by the sound generating device of the first earphone in the embodiment of the present application may be a pre-set sound signal such as speech, animal calls, or music.

[0081] Step S23: Based on the acquired sound signal, test the sound generating device of the first earphone and the sound receiving device of the second earphone.

[0082] Specifically, an acoustic performance curve of the second earphone can be generated according to the acquired sound signal, and the acoustic performances of the sound generating device of the first earphone and the sound receiving device of the second earphone can be determined based on this acoustic performance curve and a pre-set standard acoustic performance curve.

[0083] In an application scenario, only the sound generating device or the sound receiving device of the second earphone is tested. Specifically, when it is known that the sound receiving device of the first earphone is normal and the sound generating device of the second earphone is tested, the acoustic performance curve of the sound generating device of the second earphone can be determined according to the sound signal received by the sound receiving device of the first earphone, and then the acoustic performance of the sound generating device of the second earphone can be determined based on this acoustic performance curve and a pre-set standard acoustic performance curve. When it is known that the sound generating device of the first earphone is normal and the sound receiving device of the second earphone is tested, the acoustic performance curve of the sound receiving device of the second earphone can be determined according to the sound signal received by the sound receiving device of the second earphone, and then the acoustic performance of the sound receiving device of the second earphone can be determined based on this acoustic performance curve and a pre-set standard acoustic performance curve.

[0084] Taking the example that it is known that the sound receiving device of the first earphone is normal and the sound generating device of the second earphone is tested, the sound generating device of the second earphone emits a sound signal, the sound receiving device of the first earphone receives the sound signal, and an acoustic performance curve related to the frequency response and distortion of the sound generating device of the second earphone is obtained based on the received sound signal. The acoustic performance curve is compared with a pre-stored standard acoustic performance curve. If the matching degree of the two curves exceeds a pre-set matching degree (for example, 98%), it is determined that the sound generating device of the second earphone is normal, otherwise it is determined that the sound generating device of the second earphone is abnormal. Among them, the standard acoustic performance curve is the acoustic performance curve corresponding to the standard sound generating device of the second earphone, that is, the sound generating device with normal acoustic performance.

[0085] The specific detection standard can be to first test the second earphone with normal acoustic performance. The sound-emitting device of the second earphone with normal acoustic performance emits a preset sound signal, and the acoustic performance curve related to the frequency response and distortion of the sound signal obtained based on the sound signal received by the sound-receiving device of the first earphone with normal acoustic performance is used as the standard acoustic performance curve. During the test, the sound-emitting device of the second earphone also emits the same sound signal, and the acoustic performance curve related to the frequency response and distortion of the sound signal obtained based on the sound signal received by the sound-receiving device of the first earphone is compared with the above-obtained standard acoustic performance curve for a comparison test.

[0086] When testing the sound-receiving device of the second earphone, a similar method is adopted and will not be elaborated here.

[0087] In another application scenario, the acoustic performance of the sound-emitting device of the first earphone and the sound-receiving device of the second earphone is tested simultaneously, or the acoustic performance of the sound-receiving device of the first earphone and the sound-emitting device of the second earphone is tested simultaneously.

[0088] When simultaneously testing the acoustic performance of the sound-emitting device of the first earphone and the sound-receiving device of the second earphone, the corresponding acoustic performance curve related to the frequency response and distortion is determined based on the sound signal received by the sound-receiving device of the second earphone obtained. The acoustic performance curve is compared with the standard acoustic performance curve stored in advance. If the matching degree of the two curves exceeds the preset matching degree (for example, 98%), it is determined that both the sound-emitting device of the first earphone and the sound-receiving device of the second earphone are normal; otherwise, it is determined that it may be that the sound-emitting device of the first earphone and / or the sound-receiving device of the second earphone is abnormal.

[0089] Similarly, when it is determined that the curve is abnormal, further testing is required to determine whether it is the sound-emitting device of the first earphone that is abnormal, or the sound-receiving device of the second earphone that is abnormal, or both are abnormal. Specifically, the solution in this application can be adopted to separately test the sound-emitting device of the first earphone or the sound-receiving device of the second earphone, or the earphone testing equipment in the prior art can be used to separately test the sound-emitting device of the first earphone or the sound-receiving device of the second earphone.

[0090] When testing the acoustic performance of the sound-receiving device of the first earphone and the sound-emitting device of the second earphone, the sound-emitting device of the second earphone is triggered to output a sound signal, and the sound-receiving device of the first earphone is triggered to receive the sound; the sound signal received by the sound-receiving device of the first earphone is obtained; based on the obtained sound signal received by the sound-receiving device of the first earphone, the sound-receiving device of the first earphone and the sound-emitting device of the second earphone are tested. The specific implementation principle is the same as that for testing the acoustic performance of the sound-emitting device of the first earphone and the sound-receiving device of the second earphone. For details, refer to the above, and it will not be elaborated here.

[0091] In an alternative embodiment, a sound guiding pipe is provided between the output side of the sound generating device of the first earphone and the input side of the second earphone in the cavity of the charging case, and / or a sound guiding pipe is provided between the output side of the sound generating device of the second earphone and the input side of the sound receiving device of the first earphone, so that the sound signal can be transmitted to the sound receiving device of the second earphone through the sound guiding pipe.

[0092] Specifically, if the positions of the two earphones in the charging case are reasonably designed, the acoustic performance test can be completed by the method of mutual testing. For example, as Figure 2B the earphone under test in, the sound generating device of the left earphone, i.e., the first earphone, is closer to the sound receiving device of the right earphone, i.e., the second earphone, and better test results can be obtained. Further, a sound guiding pipe can be provided in the charging case, such as Figure 2C in, the pipe formed by the black line at the tail of the earphone, that is, a channel or groove is provided along the black line area in the cavity to connect the cavities at both ends. Let the sound signal of the sound generating device of the first earphone be transmitted to the sound receiving device of the second earphone through the sound guiding pipe. In addition, the sound signal emitted by the sound generating device of the first earphone should be large enough to be detected by the sound receiving device of the second earphone.

[0093] In an alternative embodiment, before triggering the sound generating device of the first earphone to output a sound signal, or after a test anomaly, the sound generating device of the first earphone is tested separately.

[0094] Specifically, in order to exclude the test result anomaly caused by the anomaly of the sound generating device of the first earphone, the sound generating device of the first earphone can be tested separately before triggering the sound generating device of the first earphone to output a sound signal. Or after a test anomaly, the sound generating device of the first earphone is tested separately. Specifically, the scheme in the present application can be used to test the sound generating device or the sound receiving device of the earphone under test separately, or the earphone test equipment in the prior art can be used to test the sound generating device or the sound receiving device of the earphone under test separately.

[0095] Alternatively, in order to exclude the test result anomaly caused by the anomaly of the sound generating device of the second earphone, the sound generating device of the second earphone can be tested separately before triggering the sound generating device of the second earphone to output a sound signal. Or after a test anomaly, the sound generating device of the second earphone is tested separately. Specifically, the scheme in the present application can be used to test the sound generating device of the second earphone separately, or the earphone test equipment in the prior art can be used to test the sound generating device of the second earphone separately.

[0096] The embodiment of the present application provides an earphone test device. For the convenience of description, only the part related to the present application is shown, such as Figure 3As shown, the headphone testing device is applied to a true wireless headphone system, which includes a charging case and the headphone under test.
