Description

Technical Field

[0001] This application relates to the field of testing technology, specifically to a headphone testing method, testing device, and storage medium. Background Technology

[0002] With the increasing variety of headphone products on the market, users are demanding higher levels of comfort. Prolonged headphone use often results in discomfort such as pain from tight fits or localized interference, or headphones falling out due to being too loose, especially since chewing or movement can easily cause them to dislodge. Therefore, headphone research and development, particularly headphone manufacturing, requires testing for wearing comfort and stability. Current methods for testing these aspects often involve numerous people wearing the headphones and subjectively evaluating them. This approach is time-consuming and labor-intensive, and its reliance on subjective feelings leads to low accuracy. Furthermore, it fails to quantify the results of comfort and stability tests. Summary of the Invention

[0003] In view of the above, it is necessary to provide a headphone testing method, testing device, and storage medium to solve the technical problems of low testing efficiency and poor reliability of headphone testing.

[0004] Firstly, embodiments of this application provide a headphone testing method applied to a testing device. The testing device includes a simulated human ear, on which the simulated human ear wears the headphone. The method includes: after initiating testing of the headphone, determining a target feature location point of the simulated human ear; detecting the pressure value of the target feature location point using a pressure sensor corresponding to the target feature location point; and indicating that the headphone test is valid if the pressure value of the target feature location point meets a preset condition. The above technical solution of this application determines the target feature location point of the simulated human ear, and when the pressure value of the target feature location point meets the preset condition, it determines that the coupling and sealing state between the headphone and the testing device is good and meets the consistency requirements of headphone testing, thereby determining that the headphone can be effectively tested, thus improving the reliability and efficiency of the test results.

[0005] In one embodiment of this application, determining the target feature location points of the simulated human ear includes: selecting multiple feature location points from the feature location points where the simulated human ear contacts the earphone as target feature location points. The target feature location points are not on the same contact surface as the earphone, or the target feature location points are not on the same straight line. By selecting feature location points that do not share a contact surface or are not collinear as target feature location points, the above technical solution can accurately determine the coupling and sealing state between the earphone and the testing device based on the pressure values ​​obtained by the pressure sensors corresponding to the target feature location points, thereby determining the reliability of the earphone test results.

[0006] In one embodiment of this application, selecting multiple feature locations from the feature locations where the simulated human ear contacts the earphone as target feature locations includes: displaying a settings interface, the settings interface including a structural diagram of the simulated human ear and controls distributed on the structural diagram of the simulated human ear for each feature location in contact with the earphone; responding to the user's selection operation on the control, determining the feature location corresponding to the selected control as the target feature location. In the above technical solution, the testing device responds to the user's selection operation on the control on the settings interface and determines the feature location corresponding to the selected control as the target feature location, which can quickly determine the target feature location.

[0007] In one embodiment of this application, the method further includes: displaying prompt information on the settings interface, the prompt information indicating feature points that do not share contact surfaces or are not collinear. The above technical solution, by displaying prompt information on the settings interface, allows users to quickly select feature points that do not share contact surfaces or are not collinear based on the prompt information.

[0008] In one embodiment of this application, the pressure value of the target feature location point meeting the preset condition includes: if the pressure value of the target feature location point is within a preset pressure range, it is determined that the pressure value of the target feature location point meets the preset condition.

[0009] In one embodiment of this application, the method further includes: if the pressure value at the target feature location does not meet a preset condition, indicating that the test on the headphones is invalid. The above technical solution, by indicating that the headphone test is invalid, signifies that the reliability of this test is poor and that a valid test cannot be performed.

[0010] Secondly, this application provides a headphone testing method applied to a testing device. The testing device includes a simulated human ear, on which the simulated human ear wears the headphone. The method includes: after starting the headphone test, determining all characteristic position points in the simulated human ear that contact the headphone; detecting the pressure value of the characteristic position points using pressure sensors corresponding to the characteristic position points; determining the contact area between the headphone and the simulated human ear based on the pressure values ​​of all characteristic position points; determining a target pressure value based on the pressure values ​​of all characteristic position points; recording the test time of the headphone in the simulated human ear; and determining a wearing comfort score based on the contact area, target pressure value, and test time. The above technical solution, when testing the headphone, obtains the pressure values ​​of the characteristic position points in the simulated human ear that contact the headphone, the contact area between the simulated human ear and the headphone, and the test time, and automatically determines the wearing comfort score based on the contact area, target pressure value, and test time. This improves the efficiency of headphone wearing comfort detection and quantifies the test results of wearing comfort.

[0011] In one embodiment of this application, determining the contact area between the earphone and the simulated human ear based on the pressure values ​​of all characteristic location points includes: determining the position coordinates of each characteristic location point; determining the distribution area of ​​all characteristic location points based on the position coordinates of each characteristic location point; and obtaining the contact area between the earphone and the simulated human ear based on the distribution area. The above technical solution can accurately determine the contact area between the earphone and the simulated human ear through the distribution area of ​​the characteristic location points.

[0012] In one embodiment of this application, obtaining the contact area between the earphone and the simulated ear based on the distribution area includes: determining the area of ​​the region formed by the distribution area as the contact area between the earphone and the simulated ear. The above technical solution can determine the contact area between the earphone and the simulated ear by calculating the area of ​​the region formed by the distribution of feature location points.

[0013] In one embodiment of this application, determining the wearing comfort score based on the contact area, target pressure value, and test time includes: based on the contact area, target pressure value, test time, and a preset wearing comfort model C=k f (f)+k s (s)+k t (t), 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 , k s , k t The preset weighting coefficient values ​​are used. The above technical solution utilizes the wearing comfort model C=k. f (f)+k s (s)+k t (t), contact area, target pressure value, and test time can be used to calculate the wearing comfort score, thereby quantifying the test results of wearing comfort.

[0014] In one embodiment of this application, determining the wearing comfort score based on the contact area, target pressure value, and test time includes: determining the corresponding wearing comfort score based on the contact area, target pressure value, test time, and a first scoring relationship, wherein the first scoring relationship includes the correspondence between the contact area, target pressure value, test time, and wearing comfort score. The above technical solution can quickly determine the wearing comfort score through the contact area, target pressure value, test time, and first scoring relationship, thereby quantifying the test results of wearing comfort.

[0015] In one embodiment of this application, determining the wearing comfort score based on the contact area, target pressure value, and test time includes: normalizing the contact area, target pressure value, and test time, and determining the wearing comfort score based on the normalized contact area, target pressure value, and test time. The above technical solution can accurately determine the wearing comfort score using the normalized contact area, target pressure value, and test time.

[0016] Thirdly, this application provides a headphone testing method applied to a testing device, which includes an artificial head and a simulated human ear mounted on the artificial head. The method includes: after starting the headphone test, determining all feature points in the simulated human ear that are in contact with the headphone; obtaining a first pressure set and a first distribution area of ​​the feature points based on the pressure value detected by the pressure sensor corresponding to each feature point; controlling the artificial head and the simulated human ear to rotate, and during the rotation of the artificial head, obtaining the pressure value detected by the pressure sensor corresponding to each feature point to obtain a second pressure set and a second distribution area of ​​the feature points; determining the positional offset of the headphone based on the first and second distribution areas; if the pressure values ​​in both the first and second pressure sets are within a preset pressure range and the positional offset of the headphone is less than a preset distance, determining that the headphone test result is stable. The above technical solution of this application, when the pressure values ​​in the first and second pressure sets are within a preset pressure range and the positional offset of the headphone is less than a preset distance, can accurately determine that the headphone measurement result is stable, thus improving the detection efficiency of headphone wearing stability and realizing the quantification of the measurement result of wearing stability.

[0017] In one embodiment of this application, obtaining the pressure value detected by the pressure sensor corresponding to each feature location point and obtaining the first distribution area includes: determining the position coordinates of each feature location point, and determining the distribution area of ​​all feature location points based on the position coordinates of each feature location point, as the first distribution area.

[0018] In one embodiment of this application, determining the positional offset of the earphone based on the first distribution region and the second distribution region includes: calculating the positional offset of the earphone based on the first distribution region and the second distribution region using an Euclidean distance algorithm or a Manhattan distance algorithm. The above technical solution, using an Euclidean distance algorithm or a Manhattan distance algorithm, can accurately determine the displacement offset of the earphone within the simulated human ear after rotation.

[0019] In one embodiment of this application, the method further includes: scoring the wearing stability of the headphones based on a first pressure set, a second pressure set, and the positional offset of the headphones.

[0020] In one embodiment of this application, the method further includes: when the pressure values ​​in the first pressure set and the second pressure set are within a preset pressure range, acquiring the audio frequency response characteristics of the headphone output sound; determining the sound pressure amplitude and standard sound pressure amplitude corresponding to a preset frequency based on the audio frequency response characteristics; and determining that the headphone test result is stable when the ratio of the sound pressure amplitude to the standard sound pressure amplitude is within a preset tolerance range. The audio frequency response characteristics represent the correspondence between the frequency of the headphone output sound and the sound pressure amplitude. The above-mentioned technical solution of this application acquires the audio frequency response characteristics of the headphone output sound and determines that the headphone test result is stable when the ratio of the sound pressure amplitude corresponding to a preset frequency to the standard sound pressure amplitude corresponding to the preset frequency is within a preset tolerance range, thus improving the accuracy of the test.

[0021] Fourthly, this application provides a testing device, which includes: an artificial head; a simulated human ear installed on the artificial head for wearing headphones; multiple pressure sensors disposed in the simulated human ear; a memory for storing program instructions; and a processor for reading and executing the program instructions stored in the memory. When the program instructions are executed by the processor, the testing device performs the aforementioned headphone testing method.

[0022] Fifthly, embodiments of this application provide a computer-readable storage medium storing program instructions that, when executed on a terminal device, cause a testing device to perform the aforementioned headphone testing method.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. It should be understood that, unless otherwise stated, " / " in this application means "or". For example, A / B can mean A or B.

For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. "At least one" refers to one or more. "More than one" refers to two or more. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, and a, b, and c (seven cases).

[0038] With the increasing variety of headphone products on the market, users are demanding higher levels of comfort. Prolonged headphone use often results in discomfort such as pain from tight fits or localized interference, or headphones falling out due to being too loose, especially since chewing or movement can easily cause them to dislodge. Therefore, headphone research and development, particularly headphone manufacturing, requires testing for wearing comfort and stability. Current methods for testing these aspects often involve numerous people wearing the headphones and subjectively evaluating them. This approach is time-consuming and labor-intensive, and its reliance on subjective feelings leads to low accuracy. Furthermore, it fails to quantify the results of comfort and stability tests.

[0039] Furthermore, during the R&D phase of headphone products, a series of audio parameters need to be measured using testing devices (such as artificial heads or simulated human ears). These measurements require a high degree of precision in the coupling seal between the headphones and the testing device (referring to the airtightness and compatibility between the headphones and the testing device when worn). Inconsistent coupling seals between the headphones and the testing device during each measurement often lead to discrepancies in low-frequency response, noise reduction, distortion, and loudness, necessitating repeated measurements and impacting the reliability and efficiency of the test results, ultimately affecting their consistency.

[0040] To ensure the consistency of headphone test results, this application provides a headphone testing method. The method is applied in a testing apparatus 10. (Reference) Figure 1The diagram shown is a schematic representation of a testing device provided in one embodiment of this application. The testing device 10 includes an artificial head 11, a simulated ear 12, a pressure sensor 13, multiple drive mechanisms 14, and a processor 15. The simulated ear 12 can be mounted on the artificial head 11. The simulated ear 12 can be used to wear headphones 20 for testing the headphones 20, such as testing the wearing consistency, wearing comfort, or wearing stability of the headphones, and collecting sound data through the headphones 20. In other embodiments, the testing device 10 may only include a simulated ear equipped with a pressure sensor, and the simulated ear can also be used independently for testing headphones. In other embodiments of this application, the simulated ear can also be mounted on other devices to implement the headphone testing method of this application.

[0041] A pressure sensor 13 may be disposed in the simulated ear 12 to acquire pressure data exerted by the earphone 20 on the simulated ear 12. In one embodiment of this application, the number of pressure sensors 13 is multiple.

[0042] refer to Figure 2 The diagram shown is a structural schematic of a simulated human ear 12 provided in an embodiment of this application. The simulated human ear 12 includes features such as the auricle, helix, cymba conchae, cavum conchae, tragus, earlobe, and external auditory canal. Multiple pressure sensors 13 can be disposed in the simulated human ear 12, corresponding to multiple feature locations projected onto the artificial head 11, in the auricle, helix, cymba conchae, cavum conchae, tragus, earlobe, external auditory canal, and other areas. These feature locations can be set according to the structural morphology of the human ear. (Reference) Figure 3 The diagram shows the distribution area of ​​feature points when the earphone is worn on a simulated human ear according to an embodiment of this application. Pressure sensors 13 corresponding to each feature point can detect the pressure value at that point, thus obtaining pressure data. It can be understood that the pressure data is distributed across the auricle, helix, cymba conchae, cavum conchae, tragus, earlobe, external auditory canal, and the connection portion from the auricle projected onto the artificial head 11 of the simulated human ear 12. In some embodiments of this application, the number of feature points can be at least 15.

[0043] The drive mechanism 14 is used to drive the artificial head 11 to rotate in at least one direction. In one embodiment of this application, the drive mechanism 14 includes a first drive sub-mechanism 141 and a second drive sub-mechanism 142. The first drive sub-mechanism 141 is used to drive the artificial head 11 in a first direction X (refer to...). Figure 1The first drive submechanism 141 rotates the artificial head 11 along the second direction Z. The first direction X is perpendicular to the second direction Z. In one embodiment of this application, the angle when the artificial head 11 looks straight ahead is defined as the base point (0°, 0°). The first drive submechanism 141 can drive the artificial head 11 to rotate within a first angle range along the first direction X based on the base point (0°, 0°) to simulate a user's head-shaking motion in the horizontal direction. The second drive submechanism 142 can drive the artificial head 11 to rotate within a second angle range along the second direction Z based on the base point (0°, 0°) to simulate a user's head-shaking motion 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 drive submechanism 141 and the second drive submechanism 142 can be at least one of the following devices: cylinder, motor, electric motor, etc.

[0044] Processor 15 may include one or more processing units, such as microprocessors, application processors (APs), modem processors, graphics processing units (GPUs), image signal processors (ISPs), controllers, video codecs, digital signal processors (DSPs), baseband processors, and / or neural network processing units (NPUs). Different processing units may be independent devices or integrated into one or more processors. Processor 15 is used to execute headphone testing methods.

[0045] The following will combine Figure 4 This application provides a detailed description of an embodiment of a headphone testing method. Figure 4 A flowchart of an earphone testing method provided in an embodiment of this application. Figure 4 The example method includes one or more steps, but does not constitute a limitation of this application. Furthermore, the order of the steps in the method is merely illustrative and may be changed. Additional steps may be added or steps may be removed without departing from the disclosure of this application. The method is applied to a testing apparatus, which can be... Figure 1 The test apparatus 10 shown can also be a simulated human ear equipped with a pressure sensor. The specific steps include the following.

[0046] Step S401: After starting the test on the headphones, determine the target feature location points of the simulated human ear.

[0047] In one embodiment of this application, after the earphone is worn in the simulated human ear of the testing device and the test is started, the testing device can test the performance of the earphone, such as low-frequency characteristics, wearing comfort, or wearing stability. The characteristic locations of the simulated human ear include the auricle, helix, cymba conchae, cavum conchae, tragus, earlobe, external auditory canal, and the projection of the auricle onto the artificial head. A pressure sensor can be correspondingly installed at each characteristic location.

[0048] In one embodiment of this application, determining the target feature location points of the simulated human ear includes: determining all feature location points in contact with the earphone; and selecting multiple feature location points from the feature location points in contact with the earphone as target feature location points. For example, at least three feature location points can be selected that do not share a contact surface or are not collinear. At least three feature location points not sharing a contact surface means that when at least three feature location points are in contact with the earphone, at least three feature location points are not on the same contact surface. At least three feature location points not collinear means that at least three feature location points are not on the same straight line.

[0049] In some embodiments of this application, because different models or brands of headphones have different shapes and structures, the characteristic contact points between the headphones and different structures in the simulated ear are also different when the headphones are worn in a simulated ear. For example, the characteristic contact points between ear-hook, in-ear, and semi-in-ear headphones and the simulated ear are different when worn in a simulated ear. Therefore, it is necessary to adjust the target characteristic point according to the shape and structure of the headphones so that the pressure value obtained by the pressure sensor corresponding to the target characteristic point can accurately reflect the pressure value when the headphones are worn in the simulated ear. In one embodiment of this application, at least three characteristic point locations that do not share a common contact surface or are not collinear are selected as target characteristic point locations. This can accurately determine the coupling and sealing state between the headphones and the test device, thereby determining the reliability of the headphone test results.

[0050] In one embodiment of this application, determining all feature locations in contact with the headphones includes: after starting the test on the headphones, acquiring the pressure values ​​collected by the pressure sensors corresponding to the feature locations of the simulated human ear; and using the feature locations corresponding to the pressure sensors that have collected non-zero pressure values ​​as the feature locations in contact with the headphones.

[0051] In some embodiments of this application, selecting multiple feature locations as target feature locations from feature locations in contact with the earphone includes: displaying a setting interface on a testing device, the setting interface including a structural diagram of a simulated human ear and controls distributed on the structural diagram of the simulated human ear for each feature location in contact with the earphone; responding to a user's selection operation on a control, such as a click operation, determining the feature location corresponding to the control as the target feature location. (See reference) Figure 5AThe diagram shown is a schematic of a settings interface provided in an embodiment of this application. The settings interface displays a structural diagram of a simulated human ear and controls for feature locations that contact the earphone, distributed on the structural diagram. By clicking the controls for feature locations on the settings interface, the user can set the corresponding feature location as the target feature location. (Reference) Figure 5B The testing device responds to the user's click operation on controls K1, K2, and K3 on the settings interface, and determines the feature location points corresponding to controls K1, K2, and K3 as target feature location points.

[0052] In one embodiment of this application, the method further includes: displaying prompt information on the settings interface, the prompt information indicating feature locations that are not on the same contact surface or not collinear, thus allowing the user to select feature locations that are not on the same contact surface or not collinear based on the prompt information. In one embodiment of this application, a first correspondence relationship of feature locations that are not on the same contact surface or not collinear is pre-stored in the testing device. The first correspondence relationship includes feature locations that are not on the same contact surface or not collinear. After the user selects a feature location, the measuring device determines other feature locations that are on the same contact surface or not collinear based on the selected feature location and the first correspondence relationship, and indicates the feature locations that are not on the same contact surface or not collinear with the selected feature location by displaying prompt information on the settings interface.

[0053] Step S402: Detect the pressure value at the target feature location point using the pressure sensor corresponding to that location point.

[0054] In one embodiment of this application, the pressure sensor of the testing device detects the pressure value once every preset period (e.g., one minute). In another embodiment of this application, the testing device can acquire the pressure value detected by the pressure sensor corresponding to the target feature location point multiple times according to a preset number of times, and take the average of the multiple pressure values ​​as the pressure value detected by the corresponding pressure sensor. In another embodiment of this application, the testing device acquires the pressure value detected by the pressure sensor corresponding to the target feature location point within a preset time period, and takes 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: Determine whether the pressure value at the target feature location point meets the preset conditions.

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

[0057] In one embodiment of this application, three non-common contact surfaces or non-collinear feature points are used as target feature points as an example. These target feature points are described as a first target feature point, a second target feature point, and a third target feature point. The first target feature point corresponds to a first preset pressure range, the second target feature point corresponds to a second preset pressure range, and the third target feature point corresponds to a third preset pressure range. Determining whether the pressure value of the target feature point is within the preset pressure range includes: determining whether the pressure value of the first target feature point is within the first preset pressure range, the pressure value of the second target feature point is within the second preset pressure range, and the pressure value of the third target feature point is within the third preset pressure range. If the pressure value of the first target feature point is within the first preset pressure range, the pressure value of the second target feature point is within the second preset pressure range, and the pressure value of the third target feature point is within the third preset pressure range, then the pressure value of the target feature point is determined to meet the preset condition. If the pressure value of the first target feature point is not within the first preset pressure range, or the pressure value of the second target feature point is not within the second preset pressure range, or the pressure value of the third target feature point is not within the third preset pressure range, then the pressure value of the target feature point is determined to not meet the preset condition.

[0058] If the pressure value at the target feature location point meets the preset conditions, step S404 is executed; if the pressure value at the target feature location point does not meet the preset conditions, step S405 is executed. In one embodiment of this application, the preset pressure range (e.g., a first preset pressure range, a second preset pressure range, and a third preset pressure range) can be represented as the pressure range within which the user experiences comfortable, stable, or consistent audio frequency response characteristics when wearing headphones. This range can be statistically obtained based on the user's wearing evaluation results (such as wearing stability evaluation results, wearing comfort evaluation results, or audio frequency response characteristic consistency evaluation results) and the recorded pressure data at the feature location points during headphone wearing experiments. Audio frequency response characteristics refer to the correspondence between the frequency of the sound output by the headphones and the sound pressure amplitude. This correspondence can be represented as a curve characteristic on a two-dimensional coordinate axis composed of the sound frequency and sound pressure amplitude.

[0059] Step S404 indicates that the headphone test is valid.

[0060] In one embodiment of this application, when the pressure value at the target feature location meets a preset condition, a voice announcement or text display indicates that the headphone test is valid. A valid test indicates that the headphone can be effectively tested, or that the headphone test is reliable. In one embodiment of this application, the pressure value at the target feature location meeting the preset condition indicates that the coupling and sealing between the headphone and the testing device is good, meeting the headphone's wearing consistency requirements. A valid test indicates that the test data or results of this headphone test are highly reliable, and that the headphone's wearing comfort, wearing stability, or audio frequency response characteristics can be effectively tested for consistency.

[0061] Step S405 indicates that the test on the headphones is invalid.

[0062] In one embodiment of this application, when the pressure value at the target feature location does not meet the preset conditions, a voice announcement or text display indicates that the headphone test is invalid. An invalid test means that the headphone cannot be effectively tested. In another embodiment of this application, the pressure value at the target feature location not meeting the preset conditions indicates poor coupling and sealing between the headphone and the testing device, failing to meet the headphone's wearing consistency requirements. An invalid test indicates that the reliability of the headphone's test data or results is poor, and effective testing of the headphone's wearing comfort and stability cannot be performed.

[0063] In several embodiments of this application, when testing the headphones by wearing them on a simulated human ear in a testing device, target feature points of the simulated human ear are determined. The validity or invalidity of the headphone test is determined by assessing whether the pressure value at the target feature point meets preset conditions. If the pressure value at the target feature point meets the preset conditions, it is determined that the coupling seal between the headphones and the testing device is good and meets the consistency requirements for headphone testing, thus constituting a valid test. By determining whether a test is valid or invalid, inconsistencies in the coupling seal between the headphones and the testing device can be avoided, which could lead to low-frequency response and inconsistent noise reduction effects in the headphone test results, thereby affecting the reliability and efficiency of the test results.

[0064] refer to Figure 6 The diagram shown is a flowchart of an earphone testing method provided in another embodiment of this application. Figure 6 The example method includes one or more steps, but does not constitute a limitation of this application. Furthermore, the order of the steps in the method is merely illustrative and may be changed. Additional steps may be added or steps may be removed without departing from the disclosure of this application. The method is applied in a testing apparatus, which can be... Figure 1 The testing device 10 shown can also be a simulated human ear equipped with a pressure sensor. The method specifically includes the following steps.

[0065] Step S601: After starting the test on the headphones, determine all the feature points in the simulated human ear that come into contact with the headphones.

[0066] In one embodiment of this application, after the earphone is worn in the simulated human ear of the testing device and the test on 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 collected a non-zero pressure value is determined as the characteristic position point in contact with the earphone.

[0067] Step S602: The pressure value at the feature location point is detected using a pressure sensor corresponding to the feature location point. In one embodiment of this application, the testing device acquires the pressure value collected by the pressure sensor corresponding to the feature location point once in each preset cycle to obtain the pressure value of the feature location point.

[0068] Step S603: Determine the contact area between the earphone and the simulated human ear based on the pressure values ​​at all feature locations.

Furthermore, the order of the steps in the method is merely illustrative and may be changed. Additional steps may be added or steps may be removed without departing from the disclosure of this application. The method is applied to a testing apparatus and specifically includes the following steps.

[0096] Step S901: After starting the test on the headphones, determine all the feature locations in the simulated human ear that come into contact with the headphones.

In one embodiment of this application, the preset frequency range is 20Hz to 20000Hz, and the preset tolerance range is + / -3dB. The standard sound pressure amplitude is the sound pressure amplitude corresponding to the preset frequency of the headphone output sound when the headphone test result is stable. This application can acquire the audio frequency response characteristics of the headphone output sound and determine that the headphone test result is stable when the ratio of the sound pressure amplitude corresponding to the preset frequency to the standard sound pressure amplitude corresponding to the preset frequency is within a preset tolerance range, thereby improving the accuracy of the test.
