[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] As mentioned in the background technology, in the prior art, the one-to-multi-bone voiceprint testing device has a high error detection rate and a technical defect of low accuracy of the test results. The inventors have found that the reason for this problem is that in the process of controlling the vibration of the vibration table in the one-to-multi-bone voiceprint testing device according to the same gain, the actual vibration amplitude of the vibration table is affected by its load-bearing weight. In other words, even if the vibration table is driven to vibrate according to the same gain, the vibration amplitude of the vibration table under different load-bearing weights is different. However, in different test processes, the number of TWS headphones carried by the one-to-multi-bone voiceprint testing device may be different, causing the load-bearing weight on the vibration table to change, thereby adversely affecting the test results, and then leading to the problem of high error detection rate and low accuracy.

[0048] For example, when the one-to-multiple-bone voiceprint test device is a one-to-four device, the vibration table carries one TWS headset in some tests and four TWS headsets in other tests. Even if the vibration table is driven to vibrate at 90dB, the actual vibration amplitude of the vibration table will be different in the above two cases, resulting in different gains of the test signals collected by the same TWS headset in the above two cases.

[0049] To solve the above problems, the present application provides a calibration method and related devices applied to a one-to-multi-bone voiceprint testing device, which can be used to calibrate the vibration table of the one-to-multi-bone voiceprint testing device, so that the calibrated vibration table can provide the TWS headphones it carries with vibration that meets the test requirements, thereby improving the stability of the bone voiceprint test and reducing the false detection rate, thereby improving the accuracy of the test results and improving the production test efficiency.

[0050] In some embodiments, the present application provides a calibration method for a one-to-many-bone voiceprint testing device, which is used to calibrate a vibration table of the one-to-many-bone voiceprint testing device.

[0051] Specifically, the one-to-many bone voiceprint testing device of the present application may include a vibration table, a vibration sensor and a carrier. The carrier is arranged on the vibration table, and carries a vibration sensor and a number of TWS headphones to be tested. Among them, the vibration sensor can be used to collect vibration signals generated by the vibration of the vibration table, for example, it can be an acceleration sensor. The number to be tested refers to the number of TWS headphones to be tested corresponding to the next bone voiceprint test. For example, if the next bone voiceprint test needs to test 1 TWS headset, the number to be tested is 1. For another example, if the next bone voiceprint test needs to test 3 TWS headphones, the number to be tested is 3.

[0052] like Figure 1 As shown, the calibration method of the one-to-many-bone voiceprint testing device provided in this application may include the following steps:

[0053] S102: Controlling the vibration of the vibration table according to a preset standard gain, and collecting a first vibration gain during the vibration process through a vibration sensor.

[0054] Among them, the standard gain can be the expected gain during the test, so that the TWS headset can complete the bone voiceprint test at the expected gain. It can be understood that the specific value of the standard gain can be pre-set according to the actual situation, and this application does not impose specific restrictions on this. The first vibration gain refers to the actual vibration gain collected by the vibration sensor in the process of driving the vibration table to vibrate according to the standard gain.

[0055] In this step, the vibration table can be controlled to vibrate continuously according to a predetermined standard gain, and during the vibration of the vibration table, the gain of the vibration signal is collected by a vibration sensor to obtain a first vibration gain. The first vibration gain can be used to reflect the bone voiceprint characteristics of the vibration table sound wave signal under the test state of the number of TWS headphones to be tested and the standard gain.

[0056] S104: Calculate a first gain deviation value between the first vibration gain and the standard gain.

[0057] In this step, the first gain deviation value can be used to reflect the degree of deviation between the first vibration gain and the standard gain, and its specific calculation method can be determined according to actual conditions, and this application does not impose specific restrictions on this. In some examples, in order to simplify the calculation method and improve the test efficiency, the difference between the standard gain and the first vibration gain or the absolute value of the difference can be used as the first gain deviation value.

[0058] S106: If the first gain deviation value is greater than the preset deviation threshold, a calibration gain is calculated according to the first gain deviation value and the standard gain.

[0059] Among them, the preset deviation threshold can be used to measure whether the degree of deviation between the first vibration gain and the standard gain is too large. If the first gain deviation value is greater than the preset deviation threshold, it means that the degree of deviation between the first vibration gain and the standard gain is too large, and the vibration table cannot provide the TWS headphones it carries with vibrations that meet the test requirements, which can easily lead to mismeasurement and reduce the accuracy of the test results. Therefore, in order to reduce the mismeasurement rate and improve the test accuracy, the present application can perform gain calibration according to the first gain deviation value and the standard gain, and thereby obtain the calibrated calibration gain after calibration.

[0060] It is understandable that the present application can use any method to complete the gain calibration, as long as it is performed based on the first gain deviation value and the standard gain. In some examples, the present application can use the sum of the first gain deviation value and the standard gain as the calibration gain.

[0061] S108: judging whether a preset abnormality judgment rule is satisfied according to the calibration gain; wherein the abnormality judgment rule is used to judge whether there is a signal acquisition abnormality in the vibration sensor.

[0062] Specifically, in some cases, the vibration sensor may have signal acquisition anomalies, so that the first vibration gain collected by the vibration sensor cannot accurately reflect the bone voiceprint characteristics of the vibration table sound wave signal. For example, when the vibration sensor is not locked, the vibration gain collected by the vibration sensor will be smaller than the actual gain, causing the collected vibration gain to be unable to accurately reflect the actual gain. If calibration is performed based on an inaccurate vibration gain, the accuracy of the vibration table calibration will be affected. Based on this, in order to eliminate the interference of vibration sensor signal acquisition anomalies on the vibration table calibration, the present application can determine whether the vibration sensor has signal acquisition anomalies based on the calibration gain obtained by calibration.

[0063] It can be understood that the specific content of the abnormal judgment rule can be determined according to the actual situation, and this application does not impose any specific restrictions on this.

[0064] S110: If not satisfied, the vibration table is controlled to vibrate according to the calibration gain, and a second vibration gain during the vibration process is collected by a vibration sensor.

[0065] In this step, if the abnormality judgment rule is not met, it indicates that there is no signal acquisition abnormality in the vibration sensor, and the first vibration gain collected by the vibration sensor can accurately reflect the bone voiceprint characteristics of the vibration table sound wave signal. In this case, the present application can control the vibration table to continue to vibrate again according to the calibration gain, and during the vibration of the vibration table, the gain of the vibration signal is collected by the vibration sensor, thereby obtaining the second vibration gain. The second vibration gain can be used to reflect the bone voiceprint characteristics of the vibration table sound wave signal under the test state of the number of TWS headphones to be tested and the calibration gain.

[0066] S112: Determine a calibration result of the vibration table based on the standard gain and the second vibration gain.

[0067] In this step, when the second vibration gain is obtained, the present application can obtain the calibration result of the vibration table according to the standard gain and the second vibration gain to determine whether the vibration table is successfully calibrated.

[0068] In the present application, the vibration table may carry a vibration sensor and a number of TWS headphones to be tested. During the calibration process, the vibration of the vibration table may first be controlled according to a preset standard gain, and the first gain deviation value between the standard gain and the first vibration gain acquired by the vibration sensor may be calculated. When the first gain deviation value exceeds the preset gain threshold, the gain calibration may be performed according to the first gain deviation value and the standard gain, and the calibration gain may be obtained. If there is no signal acquisition abnormality in the vibration sensor, the vibration of the vibration table may be controlled again according to the calibration gain, and the calibration result of the vibration table may be obtained according to the second vibration gain and the standard gain during the second vibration process. In this way, the vibration table of the one-to-many bone voiceprint test device may be calibrated, so that the calibrated vibration table can provide the TWS headphones it carries with vibrations that meet the test requirements, thereby improving the stability of the bone voiceprint test and reducing the false detection rate, thereby improving the accuracy of the test results, and improving the efficiency of production testing.

[0069] In some embodiments, judging whether a preset abnormality judgment rule is satisfied according to the calibration gain includes:

[0070] Step A1: If the calibration gain is greater than a preset gain threshold, it is determined that an abnormality judgment rule is satisfied;

[0071] Step A2: If the calibration gain is less than or equal to the preset gain threshold, it is determined that the abnormality judgment rule is not satisfied.

[0072] In this embodiment, the calibration gain can be compared with the preset gain threshold, and based on the comparison result, it can be determined whether the vibration sensor has signal acquisition abnormality. During the test, the signal acquisition abnormality of the vibration sensor is usually caused by the setting method of the vibration sensor. Common abnormal reasons include the vibration sensor being placed in an improper position and the vibration sensor not being locked. The proportion of signal acquisition abnormalities caused by sensor component failure is relatively small.

[0073] Signal acquisition anomalies caused by improper settings of the vibration sensor generally cause the vibration gain acquired by the vibration sensor to be smaller than the actual gain, and affect the numerical value of the calibration gain. Based on this, the present application can compare the calibration gain with the preset gain threshold, and determine whether the vibration sensor has signal acquisition anomalies based on the comparison result. In this way, the test efficiency can be improved while improving the accuracy of the test results.

[0074] Specifically, when the calibration gain exceeds the preset gain threshold, it indicates that the first gain deviation value is large and the first vibration gain is small, so it can be determined that the vibration sensor has a signal acquisition abnormality, that is, it is determined that the abnormality judgment rule is met. On the contrary, when the calibration gain does not exceed the preset gain threshold, it can be determined that the first gain deviation value is within an acceptable range and the first vibration gain is within an acceptable range, so it can be determined that the vibration sensor does not have a signal acquisition abnormality, that is, it does not meet the abnormality judgment rule, and steps S110 to S112 can be executed.

[0075] In some embodiments, after determining that the abnormality judgment rule is satisfied, the method further includes:

[0076] Step A3: generating a prompt message for prompting abnormality of vibration sensor signal collection;

[0077] Step A4: Send prompt information to the target terminal.

[0078] In this embodiment, when it is determined that the vibration sensor has a signal acquisition anomaly, the present application can generate a prompt message and send it to the target terminal to prompt the tester that the vibration sensor has a signal acquisition anomaly, so that the tester can intervene in time to improve the test efficiency.

[0079] In some examples, the target terminal described in this embodiment may be the acquisition control device mentioned below.

[0080] In some embodiments, determining a calibration result of the vibration table based on the standard gain and the second vibration gain includes:

[0081] Step B1: calculating a second gain deviation value between the second vibration gain and the standard gain;

[0082] Step B2: If the second gain deviation value is less than or equal to the preset deviation threshold, it is determined that the vibration table calibration is successful, and the preset headphone bone voiceprint test process is executed using the calibration gain;

[0083] Step B3: If the second gain is greater than the preset deviation threshold, it is determined that the vibration table calibration has failed.

[0084] In this embodiment, in the process of determining whether the vibration table is successfully calibrated, the second gain deviation value between the second vibration gain and the standard gain can be first calculated. For the relevant description of the second gain deviation value, please refer to the description of the first gain deviation value, which will not be repeated in this application.

[0085] It is understood that the specific calculation method of the second gain deviation value can be determined according to actual conditions, and the present application does not impose any specific restrictions on this. In one example, the difference between the standard gain and the second vibration gain can be used as the second gain deviation value.

[0086] After obtaining the second gain deviation value, the present application may compare the second gain deviation value with the preset deviation threshold to measure whether the deviation between the second vibration gain and the standard gain is too large. If the second gain deviation value is greater than the preset deviation threshold, it indicates that after calibrating the vibration table, the deviation between the second vibration gain and the standard gain is still too large, and the vibration table cannot provide the TWS headset it carries with vibration that meets the test requirements, so it can be determined that the vibration table calibration has failed.

[0087] On the contrary, if the second gain deviation value is less than or equal to the preset deviation threshold, it can be determined that the calibrated vibration table can provide the TWS headphones with vibration that meets the test requirements. Therefore, it can be determined that the vibration table calibration is successful and the preset headphone bone voiceprint test process can be executed according to the calibration gain, so that the bone voiceprint test can be performed on the number of TWS headphones to be tested carried by the vibration table based on the calibration gain.

[0088] In this embodiment, whether the vibration table is calibrated successfully can be quickly determined according to the magnitude relationship between the second gain deviation value and the preset deviation threshold.

[0089] In some embodiments, the calibration method of the present application may further include the following steps:

[0090] If the first gain deviation value is less than or equal to the preset deviation threshold, the preset headphone bone voiceprint testing process is executed using the standard gain.

[0091] Specifically, when the first gain deviation value is less than or equal to the preset deviation threshold, it indicates that the vibration table before calibration can provide the TWS headset with vibration that meets the test requirements. Therefore, the preset headset bone voiceprint test process can be directly executed according to the standard gain, so that the bone voiceprint test can be performed on the number of TWS headsets to be tested carried by the vibration table based on the standard gain.

[0092] To facilitate understanding of the solution of this application, a specific example is provided below for illustration. Figure 2 As shown, the calibration method of the one-to-many-bone voiceprint testing device provided in this example may include the following steps:

[0093] S202: Controlling the vibration of the vibration table according to the standard gain, and collecting the first vibration gain during the vibration process through a vibration sensor;

[0094] S204: taking the difference between the standard gain and the first vibration gain as a first gain deviation value;

[0095] S206: Determine whether the first gain deviation value is greater than a preset deviation threshold, if so, execute step S208, otherwise, execute step S210;

[0096] S208: taking the sum of the first gain deviation value and the standard gain as the calibration gain;

[0097] S210: Execute the preset headphone bone voiceprint test process using standard gain;

[0098] S212: Determine whether the calibration gain is greater than a preset deviation threshold, if so, end the calibration process, otherwise, execute step S214;

[0099] S214: Controlling the vibration of the vibration table according to the calibration gain, and collecting a second vibration gain during the vibration process through a vibration sensor;

[0100] S216: taking the difference between the standard gain and the second vibration gain as the second gain deviation value;

[0102] S220: Execute a preset headphone bone voiceprint test process using a calibration gain.

At the same time, the upper cover 403 may also be provided with a magnet 405. The locking mechanism may be provided on the upper cover 403 and / or the base 404, and when the locking mechanism is in a locked state, under the joint action of the locking mechanism and the magnet 405, the TWS earphone 407 is interference-pressed with the carrier.

[0129] In some examples, the center of the vibration sensor is located on the central axis of the vibration table 406, that is, the center of the vibration sensor is located on the central axis of the vibration table 406. For example, the vibration sensor can be located at Figure 5 In this way, the vibration sensor can collect more accurate vibration gain, thereby improving the calibration accuracy, and further improving the accuracy of the test results of subsequent tests.

[0130] In some examples, the one-to-many-bone voiceprint testing device 400 may further include a shock absorbing device, which is disposed under the vibration table 406 and is attached to the vibration table 406. That is, the vibration table 406 has a first end and a second end, the first end is opposite to the second end, the first end is provided with a carrier, and the second end is provided with a shock absorbing device.

[0131] It is understandable that the specific structure and implementation of the shock absorbing device can be determined according to the actual situation. For example, the shock absorbing device can be composed of marble and silicone pads to reduce the external interference signal from being transmitted to the marble and indirectly affecting the test signal of the vibration table 406.

[0132] In some examples, the acquisition control device 500 may include a signal acquisition module 510, a control host 520, and a communication network card 530 (e.g., a wireless Bluetooth Dongle), and the control host 520 is respectively connected to the signal acquisition module 510 and the communication network card 530. The communication network card 530 is communicatively connected to the vibration sensor and the TWS headset to wirelessly transmit data between the control host 520 and the vibration sensor, and wirelessly transmit data between the control host 520 and the TWS headset.

[0133] The signal acquisition module 510 is connected to the vibration table 406. The control host 520 may run the test software and display the test results through the display 401. The signal acquisition module 510 may include a power amplifier circuit, a sound card and a signal acquisition analyzer, which is used for signal acquisition and vibration source output.

[0134] In some examples, the one-to-many-bone voiceprint testing device 400 may also include a cabinet 402, which can be used to place marble, a control host 520 (such as a personal computer host), a display 401, a signal acquisition module 510, a vibration table 406, etc. During installation, the carrier, vibration sensor, vibration table 406, silicone pad, and marble can be aligned to the center position. The marble is placed using a level to detect the flatness. The carrier is used to fix the TWS headset, and the magnet 405 and the locking mechanism are used to achieve interference fit between the TWS headset 407 and the carrier.

[0135] In some examples, the test process of the TWS headset may be as follows: the control host 520 may output a signal to the wireless Bluetooth Dongle to enter the search pairing mode and connect to the TWS headset to be tested. The control signal may output a vibration signal to the vibration table 406 through the control signal acquisition module 510 to vibrate the vibration table 406. The TWS headset to be tested may collect the vibration signal and send the collected data to the control host 520 via the wireless Bluetooth Dongle. The control host 520 may output the corresponding test result after data processing and analysis.
