[0002] There are more and more types of headphone products on the market, and users have higher and higher requirements for the wearing comfort of headphones. When users wear headphones for a long time, they often feel distended and painful due to wearing too tight or local interference, or they fall off due to being too loose. Especially when wearing headphones, the headphones can easily fall off due to the user's chewing or exercise. Therefore, when developing and producing headphones, it is necessary to test the wearing comfort and wearing stability of the headphones. In the related art, the method of testing the wearing comfort and wearing stability of headphones is mostly to have a large number of people wear the headphones and then score the headphones based on their subjective feelings. This testing method is not only time-consuming and labor-intensive, but also because it relies too much on human subjective feelings, the accuracy is not high, and it is not possible to quantify the test results of wearing comfort and wearing stability. Summary of the invention

[0038] There are more and more types of headphone products on the market, and users have higher and higher requirements for the wearing comfort of headphones. When users wear headphones for a long time, they often feel distended and painful due to wearing too tight or local interference, or they fall off due to being too loose. Especially when wearing headphones, the headphones can easily fall off due to the user's chewing or exercise. Therefore, when developing and producing headphones, it is necessary to test the wearing comfort and wearing stability of the headphones. In the related art, the method of testing the wearing comfort and wearing stability of headphones is mostly to have a large number of people wear the headphones and then score the headphones based on their subjective feelings. This testing method is not only time-consuming and labor-intensive, but also because it relies too much on human subjective feelings, the accuracy is not high, and it is not possible to quantify the test results of wearing comfort and wearing stability.

[0039] In addition, during the research and development stage of headphone products, a series of audio parameter measurements need to be performed based on test devices (such as artificial heads and simulated human ear devices). When measuring audio parameters, the coupling and sealing state between the headphone and the test device (referring to the airtightness and matching degree between the headphone and the test device when the headphone is worn on the test device) is required to be high. Each time the headphone is measured by the test device, the coupling and sealing state between the headphone and the test device is often inconsistent, resulting in low-frequency response, noise reduction effect, distortion, loudness and other discrete situations in the headphone test results. The headphone needs to be worn repeatedly for measurement, which affects the credibility and efficiency of the test results, and thus affects the consistency of the test results.

[0040] In order to ensure the consistency of the test results of the earphone, the present application provides an earphone testing method. The method is applied in the testing device 10. Figure 1As shown, it is a schematic diagram of the structure of the test device provided by one embodiment of the present application. The test device 10 includes an artificial head 11, a simulated human ear 12, a pressure sensor 13, a plurality of driving mechanisms 14 and a processor 15. The simulated human ear 12 can be arranged on the artificial head 11. The simulated human ear 12 can be used to wear the earphone 20, and is used to test the earphone 20, such as testing the wearing consistency, wearing comfort or wearing stability of the earphone, and collecting sound data through the earphone 20. In other embodiments, the test device 10 may only include a simulated human ear provided with a pressure sensor, and the simulated human ear can also be used independently to test the earphone. In other embodiments of the present application, the simulated human ear can also be arranged on other devices, so as to implement the earphone testing method of the present application.

[0041] The pressure sensor 13 may be disposed in the simulated human ear 12 to obtain pressure data of the earphone 20 acting on the simulated human ear 12. In an embodiment of the present application, there are multiple pressure sensors 13.

[0042] refer to Figure 2 , which is a schematic diagram of the structure of a simulated human ear 12 provided in an embodiment of the present application. The simulated human ear 12 includes features such as an auricle, an auricle, a cymba concha, a cavum concha, a tragus, an earlobe, and an external auditory canal. A plurality of pressure sensors 13 can be arranged on the auricle, the auricle, a cymba concha, a cavum concha, a tragus, an earlobe, an external auditory canal of the simulated human ear 12, and areas corresponding to a plurality of feature position points projected from the auricle onto the artificial head 11. The feature position points can be arranged according to the structure and morphology of the human ear. Reference Figure 3 , which is a schematic diagram of the distribution area of ​​characteristic position points when the earphone provided by an embodiment of the present application is worn on a simulated human ear. The pressure sensor 13 corresponding to the characteristic position point can detect the pressure value of each characteristic position point to obtain pressure data. It can be understood that the pressure data is distributed in the auricle, helix, cymba concha, cavum concha, tragus, earlobe, external auditory canal, and the connection part where the auricle is projected to the artificial head 11 of the simulated human ear 12. In some embodiments of the present application, the number of characteristic position points can be at least 15.

[0043] The driving mechanism 14 is used to drive the artificial head 11 to rotate in at least one direction. In one embodiment of the present application, the driving mechanism 14 includes a first driving sub-mechanism 141 and a second driving sub-mechanism 142. The first driving sub-mechanism 141 is used to drive the artificial head 11 to rotate in a first direction X (reference Figure 1) is rotated, and the second driving sub-mechanism 142 is used to drive the artificial head 11 to rotate in the second direction Z. The first direction X is perpendicular to the second direction Z. In one embodiment of the present application, the angle when the artificial head 11 looks straight ahead is defined as the base point (0°, 0°). The first driving sub-mechanism 141 can drive the artificial head 11 to rotate in the first angle range according to the first direction X based on the base point (0°, 0°) to simulate the user's head swinging action in the horizontal direction. The second driving sub-mechanism 142 can drive the artificial head 11 to rotate in the second angle range according to the second direction Z based on the base point (0°, 0°) to simulate the user's head swinging action in the vertical direction. Exemplarily, the first angle range is 0° to 359°, and the second angle range is 90° to -90°. Exemplarily, the first driving sub-mechanism 141 and the second driving sub-mechanism 142 can be at least one of a cylinder, a motor, a motor and the like.

The processor 15 is used to execute the headphone testing method.

[0045] The following will be combined Figure 4 The following specifically introduces a headphone testing method provided by an embodiment of the present application. Figure 4 This is a flow chart of a headphone testing method provided in one embodiment of the present application. Figure 4 The method of the example includes one or more steps, but does not constitute a limitation of the present application. In addition, the order of the steps of the method is only an example, and the order of the steps can be changed. Additional steps can be added or steps can be reduced without departing from the content disclosed in the present application. The method is applied to a test device, and the test device can be Figure 1 The test device 10 shown may also be a simulated human ear equipped with a pressure sensor, and specifically includes the following steps.

[0046] Step S401, after starting the test on the earphone, determine the target characteristic position point of the simulated human ear.

[0047] In one embodiment of the present application, after the earphone is worn in the simulated human ear of the test device and the test of the earphone is started, the test device can test the performance of the earphone, such as low-frequency characteristics, wearing comfort or wearing stability. The characteristic position points of the simulated human ear include the auricle, helix, cymba concha, cavum concha, tragus, earlobe, external auditory canal and the projection of the auricle onto the artificial head and other characteristic position points. Each characteristic position point can be correspondingly provided with a pressure sensor.

[0048] In one embodiment of the present application, determining the target feature position points of the simulated human ear includes: determining all feature position points in contact with the earphone, selecting multiple feature position points from the feature position points in contact with the earphone as target feature position points, for example, at least three feature position points can be selected that do not share a common contact surface or are not co-linear. At least three feature position points that do not share a common contact surface means that when at least three feature position points are in contact with the earphone, at least three feature position points are not on the same contact surface in contact with the earphone. At least three feature position points that are not co-linear means that at least three feature position points are not on the same straight line.

[0049] In some embodiments of the present application, since headphones of different models or different brands have different shapes and structures, when the headphones are worn on a simulated human ear, the characteristic position points in the simulated human ear that contact the headphones of different structures are also different. For example, when headphones of ear-hook, in-ear, and semi-in-ear morphological structures are worn on a simulated human ear, the characteristic position points in the simulated human ear that contact the headphones are different. Therefore, it is necessary to adjust the target characteristic position points according to the morphological structure of the headphones, so that the pressure values ​​subsequently obtained by the pressure sensor corresponding to the target characteristic position points can accurately reflect the pressure value when the headphones are worn on the simulated human ear. In one embodiment of the present application, at least three characteristic position points that do not share a common contact surface or are not co-linear are selected as target characteristic position points, so that the coupling sealing state of the headphones and the test device can be accurately determined, so as to determine the credibility of the test results of the headphones.

[0050] In one embodiment of the present application, determining all characteristic position points in contact with the earphone includes: after starting the test of the earphone, obtaining the pressure value collected by the pressure sensor corresponding to the characteristic position point of the simulated human ear; and taking the characteristic position point corresponding to the pressure sensor that collects a non-zero pressure value as the characteristic position point in contact with the earphone.

[0051] In some embodiments of the present application, selecting multiple characteristic position points from characteristic position points in contact with the earphone as target characteristic position points includes: displaying a setting interface on the test device, the setting interface including a structure diagram of a simulated human ear and controls for each characteristic position point in contact with the earphone distributed on the structure diagram of the simulated human ear; and in response to a user's selection operation of the control, such as a click operation, determining the characteristic position point corresponding to the control as the target characteristic position point. Figure 5A, which is a schematic diagram of a setting interface provided by an embodiment of the present application. The setting interface displays a structure diagram of a simulated human ear and controls for characteristic position points in contact with the earphone distributed on the structure diagram of the simulated human ear. By clicking on the control of a characteristic position point on the setting interface, the user can set the characteristic position point corresponding to the control as the target characteristic position point. Figure 5B The test device responds to the user's click operation on the controls K1, K2, K3 on the setting interface, and determines the characteristic position points corresponding to the controls K1, K2, K3 as the target characteristic position points.

[0052] In one embodiment of the present application, the method further includes: displaying prompt information on the setting interface, the prompt information indicating the feature position points that are not co-contacting or not co-linear, so that the user can select the feature position points that are not co-contacting or not co-linear according to the prompt information. In one embodiment of the present application, the first correspondence relationship of the feature position points that are not co-contacting or not co-linear is pre-stored in the test device, and the first correspondence relationship includes the feature position points that are not co-contacting or not co-linear. After the user selects a feature position point, the measuring device determines other feature position points that are co-contacting or not co-linear based on the selected feature position point and the first correspondence relationship, and indicates the feature position points that are not co-contacting or not co-linear with the selected feature position point by displaying prompt information on the setting interface.

[0053] Step S402: Detect the pressure value of the target feature position point using the pressure sensor corresponding to the target feature position point.

[0054] In one embodiment of the present application, the pressure sensor of the test device detects a pressure value every preset period (such as one minute). In one embodiment of the present application, the test device can obtain the pressure value detected by the pressure sensor corresponding to the target feature position point multiple times according to the preset number of times, and use the average of the multiple pressure values ​​as the pressure value detected by the corresponding pressure sensor. In another embodiment of the present application, the test device obtains the pressure value detected by the pressure sensor corresponding to the target feature position point within a preset time period, and uses the average of the pressure values ​​detected within the preset time period as the pressure value detected by the corresponding pressure sensor.

[0055] Step S403, determining whether the pressure value of the target feature position point meets a preset condition.

[0056] In one embodiment of the present application, it is determined whether the pressure value of the target feature position point is within a preset pressure range. If the pressure value of the target feature position point is within the preset pressure range, it is determined that the pressure value of the target feature position point meets the preset conditions. If the pressure value of the target feature position point is not within the preset pressure range, it is determined that the pressure value of the target feature position point does not meet the preset conditions.

[0057] In one embodiment of the present application, three feature position points that are not in common contact or not in common line are taken as target feature position points as an example, and the target feature position points are described as the first target feature position point, the second target feature position point, and the third target feature position point, respectively. The first target feature position point corresponds to the first preset pressure range, the second target feature position point corresponds to the second preset pressure range, and the third target feature position point corresponds to the third preset pressure range. Determining whether the pressure value of the target feature position point is within the preset pressure range includes: determining whether the pressure value of the first target feature position point is within the first preset pressure range, whether the pressure value of the second target feature position point is within the second preset pressure range, and whether the pressure value of the third target feature position point is within the third preset pressure range. If the pressure value of the first target feature position point is within the first preset pressure range, the pressure value of the second target feature position point is within the second preset pressure range, and the pressure value of the third target feature position point is within the third preset pressure range, it is determined that the pressure value of the target feature position point meets the preset condition. If the pressure value of the first target feature position point is not within the first preset pressure range, or the pressure value of the second target feature position point is not within the second preset pressure range, or the pressure value of the third target feature position point is not within the third preset pressure range, it is determined that the pressure value of the target feature position point does not meet the preset condition.

[0058] If the pressure value of the target feature position point meets the preset condition, execute step S404; if the pressure value of the target feature position point does not meet the preset condition, execute step S405. In one embodiment of the present application, the preset pressure range (for example, the first preset pressure range, the second preset pressure range, the third preset pressure range) can be expressed as a pressure range in which the user wears the headphones comfortably, stably, or in which the audio frequency response characteristics are consistent. It can be obtained by statistically analyzing the wearing evaluation results (such as wearing stability evaluation results, wearing comfort evaluation results, or consistency evaluation results of audio frequency response characteristics) of the user recorded in the experiment of wearing headphones on the test subject and the pressure data of the recorded feature position points. The audio frequency response characteristic refers to the corresponding relationship between the frequency of the sound output by the headphones and the sound pressure amplitude. The corresponding relationship can be expressed as a curve characteristic on a two-dimensional coordinate axis consisting of the frequency and sound pressure amplitude of the sound.

[0059] Step S404, prompting that the test on the earphone is a valid test.

[0060] In one embodiment of the present application, when the pressure value at the target characteristic position point meets the preset conditions, a voice announcement or text display is used to prompt that the test on the earphone is a valid test. A valid test indicates that the earphone can be effectively tested, or indicates that the test on the earphone is reliable. In one embodiment of the present application, the pressure value at the target characteristic position point meets the preset conditions, indicating that the coupling and sealing state between the earphone and the test device is good, and the wearing consistency requirements of the earphone test are met. A valid test indicates that the test data or test results of the earphone are highly credible, and an effective test of the wearing comfort, wearing stability or consistency of the audio frequency response characteristics of the earphone can be performed.

[0061] Step S405, prompting that the test on the earphone is an invalid test.

[0062] In one embodiment of the present application, when the pressure value at the target feature position point does not meet the preset conditions, a voice announcement or text display is used to indicate that the test on the earphone is an invalid test. An invalid test means that the earphone cannot be effectively tested. In one embodiment of the present application, the pressure value at the target feature position point does not meet the preset conditions, indicating that the coupling and sealing state between the earphone and the test device is poor and does not meet the wearing consistency requirements of the earphone test. An invalid test means that the credibility of the test data or test results of this earphone is poor, and an effective test of the wearing comfort and wearing stability of the earphone cannot be performed.

[0063] In multiple embodiments of the present application, when the earphone is worn in a simulated human ear of a test device for testing, the target characteristic position points of the simulated human ear are determined, and by judging whether the pressure value of the target characteristic position points meets the preset conditions, it is determined whether the test of the earphone is a valid test or an invalid test. When it is determined that the pressure value of the target characteristic position points meets the preset conditions, it is determined that the coupling and sealing state of the earphone and the test device are good and meet the consistency requirements of the earphone test, which is a valid test. By judging the valid test and the invalid test, it is possible to avoid the situation where the test results of the earphone have a low-frequency response and the noise reduction effect is discrete due to the inconsistent coupling and sealing state between the earphone and the test device, thereby affecting the credibility and efficiency of the test results.

Figure 6 The method of the example includes one or more steps, but does not constitute a limitation of the present application. In addition, the order of the steps of the method is only an example, and the order of the steps can be changed. Additional steps can be added or steps can be reduced without departing from the content disclosed in the present application. The method is applied in a test device, and the test device can be Figure 1 The test device 10 shown may also be a simulated human ear equipped with a pressure sensor. The method specifically comprises the following steps.

[0065] Step S601, after starting the test on the earphone, all characteristic position points in the simulated human ear that are in contact with the earphone are determined.

[0066] In one embodiment of the present application, after the earphone is worn in a simulated human ear of a test device and the test of the earphone is started, the pressure value collected by the pressure sensor corresponding to the characteristic position point of the simulated human ear is determined, and the characteristic position point corresponding to the pressure sensor that collects a non-zero pressure value is determined as the characteristic position point in contact with the earphone.

[0067] Step S602: Use the pressure sensor corresponding to the characteristic position point to detect the pressure value of the characteristic position point. In one embodiment of the present application, the testing device obtains the pressure value collected by the pressure sensor corresponding to the characteristic position point once in each preset period to obtain the pressure value of the characteristic position point.

[0068] Step S603: determining the contact area between the earphone and the simulated human ear according to the pressure values ​​of all characteristic position points.

[0069] In one embodiment of the present application, determining the contact area between the earphone and the simulated human ear based on the pressure values ​​of all characteristic position points includes: determining the position coordinates of each characteristic position point; determining the distribution area of ​​all characteristic position points based on the position coordinates of each characteristic position point, and obtaining the contact area between the earphone and the simulated human ear based on the distribution area of ​​all characteristic position points. In one embodiment of the present application, the position coordinates of each characteristic position point are the coordinates of the characteristic position point corresponding to the pressure value. In one embodiment of the present application, obtaining the contact area between the earphone and the simulated human ear based on the distribution area of ​​all characteristic position points includes: determining the area formed by the distribution areas of all characteristic position points as the contact area between the earphone and the simulated human ear. Reference Figure 7 As shown, it is a schematic diagram of the distribution area of ​​the characteristic position points of the simulated human ear provided in an embodiment of the present application. Figure 7 As shown, the area area formed by the distribution area of ​​the characteristic position points of the simulated human ear is area S1, and the testing device determines area S1 as the contact area between the earphone and the simulated human ear.

[0070] Step S604: determining a target pressure value according to the pressure values ​​of all characteristic position points.

[0071] In one embodiment of the present application, the test device calculates the mean of the pressure values ​​of all characteristic position points and determines the mean as the target pressure value. In another embodiment of the present application, the test device sorts the pressure values ​​of all characteristic position points and determines the median of all pressure values ​​as the target pressure value.

[0072] Step S605, recording the test time of the earphone being tested in the simulated human ear.

In one embodiment of the present application, the test time is a preset fixed time period, so that the testing device can record the test effect of the earphone in the fixed time period.

[0074] Step S606, determining a wearing comfort score according to the contact area, the target pressure value and the test time.

[0075] In one embodiment of the present application, the contact area, target pressure value and test time are input into the wearing comfort model C=k f (f)+k s (s)+k t (t), and the wearing comfort score is calculated, where f represents the target pressure value, s represents the contact area, t represents the test time, and k f is the weight coefficient of the target pressure value, k s is the weight coefficient of the contact area, k t is the weight coefficient of the test time. In one embodiment of the present application, k f ,k s ,k t is the preset weight coefficient value. The weight coefficient k f ,k s ,k t It is obtained by fitting and correction based on the evaluation data obtained by pre-measurement. For example, in the subjective evaluation experiment, multiple earphones with different morphological structures are selected and worn normally by male and female subjects. These earphones can cover the key positions of the characteristic positions of the human ear, and the ratio of male and female subjects is equal and covers the mainstream auricle types; male and female subjects wear the earphones for different lengths of time, and the wearing comfort can be quantified by a full score of 5 or 7 points, where 1 point is the worst wearing comfort, and the higher the score, the higher the wearing comfort; male and female subjects participating in the evaluation give subjective scores for wearing comfort or distending pain based on their wearing experience to obtain evaluation data, wherein the test data includes multiple contact areas, target pressure values, test time and scoring data pairs; according to the data pairs in the evaluation data, according to the wearing comfort model C=k f (f)+k s (s)+k t (t) Fitting and correction to obtain the preset weight coefficient value k f ,k s ,k t .

[0076] In one embodiment of the present application, the testing device determines the wearing comfort score corresponding to the contact area, the target pressure value, and the test time based on the contact area, the target pressure value, the test time, and the first scoring relationship. In one embodiment of the present application, the first scoring relationship includes the corresponding relationship between the contact area, the target pressure value, the test time, and the wearing comfort score.

The preset area threshold, preset pressure threshold, and preset time threshold can be set as needed.

[0078] In one embodiment of the present application, the method further includes: determining a comfort level according to the wearing comfort score. For example, taking the full score of the comfort score as 5 points, and the comfort levels including excellent, good and poor as an example, the comfort level of a wearing comfort score of 5 points is determined as excellent; the comfort level of a wearing comfort score of 3 points or 4 points is determined as good; the comfort level of a wearing comfort score of 2 points or 2 points is determined as poor.
