Description

Technical Field

[0001] The present application relates to the field of earphone testing technology, and in particular to an earphone testing system. Background Art

[0002] The wearing comfort and stability of headphones are key factors that affect the user experience, and are also key directions for the design and improvement of headphone structures. Current evaluation methods for headphone wearing comfort and pressure basically rely on users' subjective wearing experience to give subjective scoring results of comfort and stability. This testing method relies entirely on users' subjective scoring, and is unable to obtain objective data on user comfort and stability, making it inconvenient for headphone structure design and improvement. In addition, this method has low testing efficiency and cannot be carried out in the early stages of headphone design, resulting in slower headphone R&D progress and increased costs. Therefore, there is an urgent need to build automated testing equipment and methods to achieve objective testing of headphone wearing comfort and stability, and output objective results of comfort and stability. Summary of the invention

[0003] An embodiment of the present application provides a headphone testing system, aiming to improve the accuracy of headphone testing results.

[0008] A control module is electrically connected or signal-connected to the motion capture module and the motion mechanism, and is used to calculate a shake value of the second marker relative to the first marker based on the first coordinate and the second coordinate, and to determine whether the headset is stably worn when the shake value is less than or equal to a preset shake value.

[0009] In an embodiment of the present application, a camera module is set to capture whether the relative position of the second mark and the first mark changes to describe the wearing stability of the headset. This can avoid the problem of inconsistent subjective evaluation standards of users on wearing stability and improve the accuracy of the test results of the wearing stability of the headset.

[0013] In the embodiment of the present application, during the shaking test of the earphone, the earphone may rotate or shift relative to the human ear model, etc. Therefore, the embodiment calculates the shaking value S of the earphone in combination with the rotation standard deviation, the shift distance and the shaking acceleration of the earphone to improve the accuracy of the test.

[0014] The control module calculates the rotation standard deviation, offset distance and shake acceleration of the headset according to the position change of the second marking point relative to the first marking point in the three-dimensional coordinate system, and combines the rotation standard deviation, offset distance and shake acceleration into the above formula to obtain the shake value of the headset.

The camera module can also transmit the first coordinate and the second coordinate to the control module. The control module can establish a three-dimensional coordinate system based on the first coordinate of the first mark, and convert the second coordinate of the second mark into the three-dimensional coordinate system. The control module displays the position change of the second mark relative to the first mark in the three-dimensional coordinate system in real time, and reflects the wearing stability of the earphone by calculating whether the second mark shakes relative to the first mark in the three-dimensional coordinate system and the shaking value of the shaking.

[0020] In a possible design, there are at least eight cameras, and the at least eight cameras are arranged on the periphery of the human ear model and are evenly spaced along the same circumference.

[0080] In an embodiment of the present application, since different locations in different areas of the human ear have different sensitivities to pressure, the pressure conditions at different locations will affect the user's perception and evaluation of the wearing comfort of the headphone. Therefore, an embodiment of the present application sets multiple pressure sensors distributed in various areas of the human ear model.

[0081] Among them, the first sensor, the second sensor, the third sensor, the fourth sensor, the fifth sensor and the sixth sensor can be set in multiple numbers to increase the collected data and further ensure accurate description of the wearing comfort of the headset.

[0099] The control module can evaluate the wearing stability of the earphones based on the analysis results of the calculated shaking value. Specifically, the maximum value of the earphone shaking allowed is defined as a preset shaking value. When the shaking value is less than or equal to the preset shaking value, the earphones are stable when worn; and when the shaking value is greater than the preset shaking value, the earphones are unstable when worn.

The camera module can also transmit the first coordinate and the second coordinate to the control module. The control module can establish a three-dimensional coordinate system based on the first coordinate of the first mark, and convert the second coordinate of the second mark into the three-dimensional coordinate system.

[0118] ;

[0119] in, is an empirical constant, is the maximum pressure in different areas of the human ear model, The average pressure in different areas of the human ear model.

[0120] In an embodiment of the present application, since different locations in different areas of the human ear have different sensitivities to pressure, the pressure conditions at different locations will affect the user's perception and evaluation of the wearing comfort of the headphone. Therefore, an embodiment of the present application sets multiple pressure sensors distributed in various areas of the human ear model.

[0121] Based on the collection of pressure values ​​of each area according to different human ear model areas to characterize the wearing comfort of the earphones, the embodiment of the present application also combines the pressure values ​​of each area of ​​the human ear model to calculate the overall pressure exerted by the earphones on the human ear model, so as to further derive the overall pressure felt by the user when wearing the earphones.

[0146] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0147] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0148] In a specific embodiment, the present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0149] When consumers choose wearable products, they focus on the comfort and stability of the product when wearing it. For example, for headphones, consumers will pay attention to whether the structure of the headphones will cause wearing pressure, whether the headphones can remain stable during walking or running, and whether they are easy to slip off.

[0150] The current testing method is to recruit real users to wear headphones, repeatedly test the wearing comfort and stability, and then collect user feedback on the wearing experience. However, different users have different subjective evaluation criteria for the wearing comfort and stability of headphones, which may affect the stability of the test results.

[0151] To this end, this embodiment provides a headphone testing system to solve the above technical problems.

[0152] like Figure 1 The schematic diagram of the earphone test system 1 is shown in the figure. The earphone test system 1 has a first direction X, a second direction Y and a third direction Z. The earphone test system includes a human ear model, which is used to simulate the ear of a user. Taking the human ear model 11 on the earphone test system 1 as a reference, the area between the two human ear models 11 is the human head area. The first direction X is defined as the left-right direction of the human head, the second direction Y is the up-down direction of the human head, and the third direction Z is the front-back direction of the human head. The directions of the first direction X, the second direction Y and the third direction Z are substantially perpendicular.

[0153] Figure 2 Shown Figure 1 Please refer to the signal transmission block diagram of the headphone test system 1 shown in FIG. Figure 1 and Figure 2 The test system 1 includes a human ear model 11, a motion mechanism 12, a motion capture module 13, a pressure measurement module 14 and a control module 15. The human ear model 11 is installed on the motion mechanism 12 for wearing headphones (not shown in the figure). The motion mechanism 12, the motion capture module 13 and the pressure measurement module 14 are all electrically connected or signal-connected to the control module 15. Specifically, the control module 15 can control the movement of the motion mechanism 12, and at the same time, the control module 15 can start the motion capture module 13 and the pressure measurement module 14 to collect information, and the information obtained by the motion capture module 13 and the pressure measurement module 14 can be transmitted to the control module 15.

[0154] Specifically, the control module 15 can control the motion mechanism 12 to drive the human ear model 11 to simulate the movement of the human head, so as to simulate the scene of the user wearing headphones. In the test scene, the motion capture module 13 can capture the shaking of the headphones and transmit the data to the control module 15. The pressure measurement module 14 can collect the pressure values ​​of each area in the human ear model 11 and transmit the data to the control module 15, so that the control module 15 can display the shaking and pressure conditions of the headphones in real time. After the headphones complete the shaking test and pressure test in the test scene, the control module 15 will compare the test value of the headphones with the preset standard value and output the test results.

[0155] In this embodiment, the control system controls the motion mechanism 12 to drive the human ear model 11 to move along a preset trajectory, thereby simulating the state of a user wearing headphones in various test scenarios (such as static scenarios and motion scenarios). The control module 15 evaluates the data detected by the motion capture module 13 and the pressure measurement module 14, unifies the test standards of the headphones, ensures the objectivity of the test results, and improves the accuracy of the test results of the wearing stability and comfort of the headphones.

[0156] At the same time, by using the motion mechanism 12 to simulate the movement of the human head and using the human ear model 11 to simulate the user wearing headphones, the traditional testing process that requires the user to wear headphones for testing can be omitted, thereby simplifying the testing process and improving testing efficiency.

[0157] The following will describe in detail the content of detecting the shaking of the earphone by the motion capture module 13 in conjunction with the accompanying drawings.

[0158] Please continue to refer to Figure 1 and Figure 2 The motion capture module 13 includes a camera module 131, and the camera module 131 is located above the human ear model 11. A first mark 111 is provided on the human ear model 11, and a second mark (not shown in the figure) is provided on the earphone.

[0159] When detecting the shaking of the earphone, the camera module 131 can capture the first coordinate of the first mark 111 on the human ear model 11 and the second coordinate of the second mark on the earphone in real time, wherein the first coordinate is the three-dimensional space coordinate data of the first mark, and the second coordinate is the three-dimensional space coordinate data of the second mark. The camera module can also transmit the first coordinate and the second coordinate to the control module 15. The control module 15 can establish a three-dimensional coordinate system based on the first coordinate of the first mark 111, and convert the second coordinate of the second mark into the three-dimensional coordinate system. The control module 15 displays the position change of the second mark relative to the first mark 111 in the three-dimensional coordinate system in real time, and reflects the wearing stability of the earphone by calculating whether the second mark relative to the first mark 111 shakes in the three-dimensional coordinate system and the shaking value of the shaking.

[0160] In this embodiment, by setting the camera module 131 to capture whether the relative position of the second mark and the first mark 111 changes to describe the wearing stability of the headset, the problem of inconsistent subjective evaluation standards of users on wearing stability can be avoided, and the accuracy of the test results of the wearing stability of the headset can be improved.

[0161] Specifically, the control module 15 can evaluate the wearing stability of the earphone according to the analysis result of the calculated shaking value. Specifically, the maximum value of the earphone shaking allowed is defined as a preset shaking value. When the shaking value is less than or equal to the preset shaking value, it indicates that the earphone is stable when worn; and when the shaking value is greater than the preset shaking value, it indicates that the earphone is unstable when worn.

[0162] In some embodiments, the first mark 111 includes a plurality of first mark points, and the second mark includes a plurality of second mark points corresponding to and matching the first mark points. That is, each first mark point has a second mark point as a reference point. For example, the first mark point and the second mark point can be set to four, the first mark points are the first point position, the second point position, the third point position and the fourth point position, and the second mark points are the fifth point position, the sixth point position, the seventh point position and the eighth point position. In the process of testing the stability of the headset, the camera module captures the position changes of the first point position, the second point position, the third point position, the fourth point position, the fifth point position, the sixth point position, the seventh point position and the eighth point position in real time, and transmits the position information to the control module. Among them, the first point position and the fifth point position are two corresponding matching points, and the control module compares the position information of the fifth point position and the first point position to obtain the position change of the fifth point position relative to the first point position. The second point position and the sixth point position are two corresponding matching points, and the control module compares the position information of the sixth point position and the second point position to obtain the position change of the sixth point position relative to the second point position. The third point and the seventh point are two corresponding matching points. The control module compares the position information of the seventh point and the third point to obtain the position change of the seventh point relative to the third point. The fourth point and the eighth point are two corresponding matching points. The control module compares the position information of the eighth point and the fourth point to obtain the position change of the eighth point relative to the fourth point. Therefore, by setting a plurality of one-to-one corresponding matching first marking points and second marking points, more data can be provided for the control module to accurately analyze, thereby improving the accuracy of the calculated position change of the second mark relative to the first mark.

[0163] The first marking point and the second marking point may be optical marking points. In this embodiment, the specific spatial position, direction, and motion trajectory of the marking point can be obtained by observing and positioning the marking point with multiple camera modules to obtain a three-dimensional coordinate system. The principle of the camera module 131 capturing the marking point to form a three-dimensional coordinate system belongs to the existing technology in the field, and this embodiment will not be repeated here.

[0164] like Figure 3 The figure shows a top view of the earphone testing system 1. The camera module 131 includes a plurality of cameras 131a arranged around the human ear model 11 and the earphone. The plurality of cameras 131a can capture the positions of the first marking point on the human ear model 11 and the second marking point on the earphone.

[0165] It should be noted that at least three cameras 131a are required to capture the motion trajectory of any first marking point on the human ear model 11 and the corresponding second marking point on the earphone to increase the sampling rate and ensure the accuracy of motion capture.

[0166] If so, please continue to refer to Figure 3 In some embodiments, the camera module 131 is provided with 8 cameras 131a, and the 8 cameras 131a are evenly arranged around the human ear model 11 and the earphone, that is, the angle between two adjacent cameras is 45°, so that at least 3 cameras 131a are provided in each direction to capture the marking points of the human ear model 11 and the earphone.

[0167] For example, please refer to Figure 4 , Figure 4 FIG. 1 is a side view of another embodiment of the headphone test system 1. The camera module 131 is provided with 16 cameras 131a. The 16 cameras 131a are divided into two layers along the second direction Y, and each layer is provided with 8 cameras 131a. The 8 cameras 131a of each layer are evenly arranged around the human ear model 11 and the headphone. The arrangement of the 8 cameras 131a of each layer is the same as Figure 3 The embodiment shown is similar. Figure 4 The arrangement shown enables at least six cameras 131a to be arranged in each direction to capture the marking points of the human ear model 11 and the earphone.

[0168] In some embodiments, during the shake test of the earphone, the earphone may rotate or shift relative to the human ear model 11. Therefore, this embodiment calculates the shake value of the earphone by combining the rotation standard deviation, the shift distance and the shake acceleration of the earphone. , improve the accuracy of the test.

[0169] Headphone shaking value for:

[0170] ;

[0171] in, is an empirical constant, and the parameters of different headphone types are different, is the standard deviation of headphone rotation, Offset distance for headphones, Shake the headset to accelerate.

[0172] That is, the control module 15 calculates the rotation standard deviation, offset distance and shake acceleration of the earphone according to the position change of the second marking point relative to the first marking point in the three-dimensional coordinate system, and combines the rotation standard deviation, offset distance and shake acceleration into the above formula to obtain the shake value of the earphone.

[0173] After obtaining the shaking value of the earphone, the shaking condition of the earphone is obtained by comparing the shaking value with the preset shaking value. When the shaking value is less than or equal to the preset shaking value, it indicates that the earphone is worn stably; and when the shaking value is greater than the preset shaking value, it indicates that the earphone is worn unstably.

[0174] The following will describe in detail the contents of the pressure testing module detecting the earphone pressure condition in conjunction with the accompanying drawings.

[0175] Please refer to Figure 5 , Figure 5 for Figure 1 The schematic diagram of the structure of the part involving pressure test in FIG. 1 shows that the pressure measurement module 14 includes a pressure sensor 141 and a data transmitter 142 which are electrically or signal-connected. The data transmitter is electrically or signal-connected to the control module. There are multiple pressure sensors 141 which are arranged in various areas of the human ear model 11. The data transmitter 142 is installed on the motion mechanism 12.

[0176] When the human ear model 11 wears the earphone, there will be contact pressure between the human ear model 11 and the earphone, and the contact pressure can simulate the contact pressure when the human ear wears the earphone. At this time, the pressure sensor 141 can collect the pressure values ​​of each area in the human ear model 11. The data transmitter 142 can transmit the pressure data collected by the pressure sensor 141 to the control module 15, and the control module 15 reflects the wearing comfort of the earphone through the pressure value.

[0177] In this embodiment, by setting multiple pressure sensors 141 to collect pressure values ​​to describe the wearing comfort of the earphone, the problem of inconsistent subjective evaluation standards of users on the wearing comfort of the earphone can be avoided, and the accuracy of the test results of the wearing comfort of the earphone can be improved.

[0178] It can be understood that since different areas and positions in the human ear have different sensitivities to pressure, the pressure conditions at different positions will affect the user's perception and evaluation of the wearing comfort of the earphones. Therefore, this embodiment sets multiple pressure sensors 141 distributed in various areas of the human ear model 11, which is explained in detail below.

[0179] Please refer to Figure 6a and Figure 6b , Figure 6a and Figure 6b All of them are schematic diagrams of the human ear model 11, where Figure 6a is a schematic diagram of the front side of the human ear model 11, Figure 6bSchematic diagram of the back of the human ear model 11. The human ear model 11 has an external auditory canal 112, a concha cavity 113, a tragus 114, a crus helix 115, a back of the ear 116 and an upper edge of the antihelix (not shown in the figure). The pressure sensor 141 includes a plurality of sensors distributed in corresponding areas in the human ear model 11, namely, a first sensor 141a arranged in the external auditory canal 112, a second sensor 141b arranged in the concha cavity 113, a third sensor 141c arranged in the tragus 114, a fourth sensor 141d arranged in the crus helix 115, a fifth sensor 141e arranged in the back of the ear 116 and a sixth sensor arranged in the upper edge of the antihelix (not shown in the figure).

[0181] The second sensor 141b is Figure 6a The middle square structure indicates that a plurality of second sensors 141b are distributed in the concha cavity 113. The second sensor 141b can collect the pressure value of the concha cavity 113. The pressure value collected by the second sensor 141b reflects the pressure condition of the concha cavity 113.

[0182] The third sensor 141c is Figure 6a The middle triangle structure indicates that a plurality of third sensors 141c are distributed on the tragus 114 . The third sensors 141c can collect pressure values ​​of the tragus 114 . The pressure values ​​collected by the third sensors 141c reflect the pressure conditions of the tragus 114 .

[0183] The fourth sensor 141d is composed of Figure 6a The middle diamond structure indicates that a plurality of fourth sensors 141d are distributed on the helix crus 115 . The fourth sensors 141d can collect pressure values ​​of the helix crus 115 . The pressure values ​​collected by the fourth sensors 141d reflect the pressure conditions of the helix crus 115 .

[0184] The fifth sensor 141e is composed of Figure 6b The middle straight line structure indicates that a plurality of fifth sensors 141e are distributed behind the ear 116. The fifth sensor 141e can collect the pressure value behind the ear 116. The pressure value collected by the fifth sensor 141e reflects the pressure condition behind the ear 116.

[0185] A plurality of sixth sensors are distributed on the upper edge of the antihelix. The sixth sensors can collect pressure values ​​on the upper edge of the antihelix. The pressure values ​​collected by the sixth sensors reflect the pressure conditions on the upper edge of the antihelix.

[0186] Furthermore, the control module 15 of this embodiment evaluates the wearing comfort of the earphone according to the analysis result of the pressure value collected by the pressure sensor 141 .

[0187] Specifically, the maximum pressure value allowed in the external auditory canal 112 is defined as a first preset pressure value. When the pressure value collected by the first sensor 141a is less than or equal to the first preset pressure value, it indicates that the earphone is comfortable to wear; and when the pressure value collected by the first sensor 141a is greater than the first preset pressure value, it indicates that the earphone is uncomfortable to wear.

[0188] The average value of the pressure values ​​collected by the multiple first sensors 141a can be used to describe the wearing comfort of the headset. Specifically, the smaller the average value of the pressure values ​​collected by the multiple first sensors 141a is, the better the wearing comfort of the headset is; the larger the average value of the pressure values ​​collected by the multiple first sensors 141a is, the worse the wearing comfort of the headset is.

[0189] The maximum pressure value allowed in the concha cavity 113 is defined as a second preset pressure value. When the pressure value collected by the second sensor 141b is less than or equal to the second preset pressure value, it indicates that the earphone is comfortable to wear; and when the pressure value collected by the second sensor 141b is greater than the second preset pressure value, it indicates that the earphone is uncomfortable to wear.

[0190] The average value of the pressure values ​​collected by the multiple second sensors 141b can be used to describe the wearing comfort of the headset. Specifically, the smaller the average value of the pressure values ​​collected by the multiple second sensors 141b, the better the wearing comfort of the headset; the larger the average value of the pressure values ​​collected by the multiple second sensors 141b, the worse the wearing comfort of the headset.

[0191] The maximum pressure value allowed in the auricle 114 is defined as a third preset pressure value. When the pressure value collected by the third sensor 141c is less than or equal to the third preset pressure value, it indicates that the earphone is comfortable to wear; and when the pressure value collected by the third sensor 141c is greater than the third preset pressure value, it indicates that the earphone is uncomfortable to wear.

[0192] The average value of the pressure values ​​collected by the third sensors 141c can be used to describe the wearing comfort of the headset. Specifically, the smaller the average value of the pressure values ​​collected by the third sensors 141c is, the better the wearing comfort of the headset is; the larger the average value of the pressure values ​​collected by the third sensors 141c is, the worse the wearing comfort of the headset is.

[0193] The maximum pressure value allowed at the helix crus 115 is defined as a fourth preset pressure value. When the pressure value collected by the fourth sensor 141d is less than or equal to the fourth preset pressure value, it indicates that the earphone is comfortable to wear; and when the pressure value collected by the fourth sensor 141d is greater than the fourth preset pressure value, it indicates that the earphone is uncomfortable to wear.

[0194] The average value of the pressure values ​​collected by the fourth sensors 141d can be used to describe the wearing comfort of the headset. Specifically, the smaller the average value of the pressure values ​​collected by the fourth sensors 141d is, the better the wearing comfort of the headset is; the larger the average value of the pressure values ​​collected by the fourth sensors 141d is, the worse the wearing comfort of the headset is.

[0195] The maximum pressure value allowed in the area behind the ear 116 is defined as the fifth preset pressure value. When the pressure value collected by the fifth sensor 141e is less than or equal to the fifth preset pressure value, it indicates that the earphone is comfortable to wear; and when the pressure value collected by the fifth sensor 141e is greater than the fifth preset pressure value, it indicates that the earphone is uncomfortable to wear.

[0196] The average value of the pressure values ​​collected by the multiple fifth sensors 141e can be used to describe the wearing comfort of the headset. Specifically, the smaller the average value of the pressure values ​​collected by the multiple fifth sensors 141e is, the better the wearing comfort of the headset is; the larger the average value of the pressure values ​​collected by the multiple fifth sensors 141e is, the worse the wearing comfort of the headset is.

[0197] The maximum pressure value allowed at the upper edge of the helix is ​​defined as a sixth preset pressure value. When the pressure value collected by the sixth sensor is less than or equal to the sixth preset pressure value, it indicates that the earphone is comfortable to wear; and when the pressure value collected by the sixth sensor is greater than the sixth preset pressure value, it indicates that the earphone is uncomfortable to wear.

[0198] The average value of the pressure values ​​collected by the sixth sensors can be used to describe the wearing comfort of the headset. Specifically, the smaller the average value of the pressure values ​​collected by the sixth sensors is, the better the wearing comfort of the headset is; the larger the average value of the pressure values ​​collected by the sixth sensors is, the worse the wearing comfort of the headset is.

[0199] It should be noted that in the above embodiment, the pressure sensor 141 is set at a position in the human ear that is more sensitive to pressure, so as to ensure that the collected pressure value can accurately reflect the pressure condition when the human ear model 11 wears headphones. Alternatively, the pressure sensor 141 can also be set at other positions in the human ear model 11, which can be set according to actual conditions, and this embodiment is not limited here.

[0200] In some embodiments, based on the above-mentioned method of collecting pressure values ​​of each area of ​​the human ear model 11 to characterize the wearing comfort of the earphone, this embodiment also combines the pressure values ​​of each area of ​​the human ear model 11 to calculate the overall pressure applied by the earphone to the human ear model 11, so as to further obtain the overall pressure felt by the user when wearing the earphone.

[0201] The overall pressure value of the human ear model 11 exerted by the earphone for:

[0202] ;

[0203] in, are empirical constants (1 is the external auditory canal, 2 is the concha cavity, 3 is the tragus, 4 is the helix crus, 5 is the back of the ear, and 6 is the upper edge of the antihelix), parameters of different headphone types different, The maximum pressure values ​​of 11 different areas of the human ear model (external auditory canal, concha cavity, tragus, helix crus, back of the ear, and upper edge of the antihelix) are shown in Table 1. The average pressure value of different regions of the human ear model 11 (external auditory canal, concha cavity, tragus, helix crus, back of the ear, and upper edge of the antihelix). Among them, the maximum pressure value of different regions of the human ear model 11 (external auditory canal, concha cavity, tragus, helix crus, back of the ear, and upper edge of the antihelix) The average pressure values ​​of different areas (external auditory canal, concha cavity, tragus, helix crus, back of ear, and upper edge of antihelix) of the human ear model 11 can be obtained from the pressure values ​​collected by the pressure sensors in the corresponding areas over a period of time. It can be calculated by collecting pressure values ​​from pressure sensors in the corresponding area over a period of time.

[0204] That is, by combining the maximum pressure value and the average pressure value of each area of ​​the human ear model 11 collected by the pressure sensor 141 into the above formula, the overall pressure value applied by the earphone to the human ear model 11 can be roughly obtained. This overall pressure value is closest to the pressure value that the human body is subjected to when wearing the earphone.

[0205] The maximum overall pressure value allowed by the human ear model 11 is defined as a preset overall pressure value. When the overall pressure value is less than or equal to the preset overall pressure value, it indicates that the earphone is comfortable to wear; and when the overall pressure value is greater than the preset overall pressure value, it indicates that the earphone is uncomfortable to wear.

[0206] When the earphone is subjected to the shaking and pressure test as described above, the control module 15 controls the motion mechanism 12 to drive the human ear model 11 and the earphone to move, so as to simulate the test of the earphone in different scenes, such as dynamic scenes. That is, the motion mechanism can realize the dynamic scenes of the earphone.

[0207] The possible structure of the motion mechanism 12 will be described in detail below with reference to the accompanying drawings.

[0208] like Figure 7 The figure shows a schematic diagram of a human ear model 11 installed on a motion mechanism 12 . The motion mechanism 12 includes a mounting frame 121 , a first rotating assembly 122 , a second rotating assembly 123 , a first moving assembly 124 , a second moving assembly 125 and a third moving assembly 126 .

[0209] The human ear model 11 is mounted on a mounting frame 121, and the mounting frame 121 is mounted on a first rotating assembly 122. The first rotating assembly 122 can drive the mounting frame 121 to rotate around a first direction X, so as to realize the rotation of the human ear model 11 and the earphone around the first direction X, thereby simulating the scene when the user wears the earphone and turns his head forward and backward. The first rotating assembly 122 is mounted on a second rotating assembly 123, and the second rotating assembly 123 can drive the first rotating assembly 122 to rotate around a second direction Y, so as to realize the rotation of the human ear model 11 and the earphone around the second direction Y, thereby simulating the scene when the user wears the earphone and turns his head left and right. The second rotating assembly 123 is mounted on a first moving assembly 124, and the first moving assembly 124 can drive the second rotating assembly 123 to move along the second direction Y, so as to realize the movement of the human ear model 11 and the earphone along the second direction Y, thereby simulating the scene when the user wears the earphone and moves in the up and down directions. The first moving component 124 is mounted on the second moving component 125, and the second moving component 125 can drive the first moving component 124 to move along the first direction X, so as to realize the movement of the human ear model 11 and the earphone along the first direction X, thereby simulating the scene when the user wears the earphone and moves in the left and right directions. The third moving component 126 is mounted on the second moving component 125, and the third moving component 126 can drive the second moving component 125 to move along the third direction Z, so as to realize the movement of the human ear model 11 and the earphone along the third direction Z, thereby simulating the scene when the user wears the earphone and moves in the front and back directions.

[0210] In this embodiment, the motion mechanism 12 is provided to drive the human ear model 11 to simulate the motion state of the human body, thereby reducing the time and cost of manual testing, unifying the testing standards, and enabling comparison between multiple headphones.

[0211] Specifically, please refer to Figure 8 , Figure 8The schematic diagram of the cooperation between the human ear model 11, the mounting frame 121 and the first rotating assembly 122 is shown. The first rotating assembly 122 drives the human ear model 11 to rotate around the first direction X through the mounting frame 121. The first rotating assembly 122 includes a first motor 122a, a first gear 122b and a second gear 122c. The driving shaft of the first motor 122a is sleeved with the first gear 122b, the first gear 122b is meshed with the second gear 122c, and the second gear 122c is sleeved with the mounting frame 121. The driving shaft of the first motor 122a drives the first gear 122b to rotate around the first direction X. The first gear 122b and the second gear 122c are meshed and transmitted, so that the second gear 122c drives the mounting frame 121 to rotate around the first direction X, thereby realizing the rotation of the human ear model 11 around the first direction X.
