Description

Technical Field

[0001] This invention relates to the field of headphone technology, and in particular to a headphone wearing comfort testing device and a headphone wearing comfort testing method. Background Technology

[0002] With the rapid development of science and technology and the continuous improvement of living standards, users are paying more attention to the comfort of products, especially wearable products that come into direct contact with the human body, such as in-ear headphones. Since people spend a considerable amount of time wearing headphones, their comfort is extremely important; incorrect wearing methods can cause ear discomfort. Therefore, people are increasingly concerned about the comfort of wearing headphones.

[0003] Currently, the main method for detecting headphone pressure is to install a pressure detection device in a human ear model to test the pressure of different headphones in the ear canal, thereby obtaining a basis for adjusting wearing comfort, such as patent CN202011126217.9.

[0004] Furthermore, patent CN202011052401.3 discloses a device and method for detecting the wearing comfort of headphones. The detection device includes a head model and multiple pressure sensors, which are distributed on the wearing area of ​​the head model to collect pressure values ​​at the wearing area, thus serving as a standard for judging comfort. However, this method requires numerous users to repeatedly test the wearing comfort, collect user feedback, and make corresponding structural modifications. This results in a large amount of repetitive work, negatively impacting the headphone development cycle. Moreover, different users have inconsistent subjective evaluation standards for headphone wearing comfort, which to some extent affects the accuracy of the test results. Additionally, generally, users do not feel discomfort in their ear canals when first wearing headphones, but discomfort only arises after prolonged use, making it difficult to grasp the user's real-time experience. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a headphone wearing comfort detection device and a headphone wearing comfort detection method, which can realize active ear pressure detection, thereby adjusting the wearing comfort.

[0006] To address the aforementioned technical problems, this invention provides a headphone wearing comfort detection device, comprising: a flexible earplug, an electrode layer, a pressure-sensitive layer, and a processor. The flexible earplug includes an earpiece portion and a flexible ear cap portion connected to each other. The surface of the flexible ear cap portion that contacts the inner wall of the ear canal is the outer cap surface, and the surface that contacts the earpiece portion is the inner cap surface. The electrode layer is disposed on the surface of the earpiece portion, and the pressure-sensitive layer is disposed on the inner cap surface of the flexible ear cap portion. When the pressure-sensitive layer and the electrode layer are in contact, a resistance signal is generated based on the real-time contact state. The electrode layer is electrically connected to the processor and is used to send the resistance signal to the processor. The processor is used to generate pressure information based on the resistance signal.

[0007] As an improvement to the above solution, the processor is also used to generate and output comfort reminder information based on the pressure information.

[0008] As an improvement to the above solution, the electrode layer and / or pressure-sensitive layer are integrated onto the flexible earpiece using 3D printing.

[0009] As an improvement to the above scheme, the smaller the value of the resistance signal, the larger the value of the pressure information.

[0010] Accordingly, the present invention also provides a method for detecting earphone wearing comfort based on an earphone wearing comfort detection device, comprising: wearing the earphone wearing comfort detection device in the user's ear canal; adjusting the real-time position of the earphone wearing comfort detection device in the ear canal until the user feels discomfort in the ear canal; when the user feels discomfort in the ear canal, acquiring the pressure information detected by the earphone wearing comfort detection device, and using the pressure information as the user's initial wearing comfort pressure standard value.

[0011] As an improvement to the above solution, the headphone wearing comfort detection method further includes: acquiring pressure information detected by the headphone wearing comfort detection device in real time; comparing the pressure information with the initial wearing comfort pressure standard value; and generating a comfort reminder message when the pressure information is greater than or equal to the initial wearing comfort pressure standard value to remind the user that the ear canal will be uncomfortable.

[0012] As an improvement to the above solution, the headphone wearing comfort detection method further includes: adjusting the real-time position of the headphone wearing comfort detection device in the ear canal so that the pressure information detected by the headphone wearing comfort detection device is less than the initial wearing comfort pressure standard value; and acquiring the pressure information detected by the headphone wearing comfort detection device when the user feels discomfort in the ear canal again.

[0013] As an improvement to the above solution, the headphone wearing comfort detection method further includes: recording the wearing time information when the user feels discomfort in the ear canal again.

[0014] As an improvement to the above solution, the headphone wearing comfort detection method further includes: setting a standard value for wearing duration based on the wearing duration information, wherein the standard value for wearing duration is less than the wearing duration information; detecting the user's headphone wearing time in real time; comparing the headphone wearing time with the preset standard value for wearing duration; and generating a comfort reminder message when the headphone wearing time equals the standard value for wearing duration to remind the user that their ear canal will feel uncomfortable.

[0015] Implementing this invention has the following beneficial effects:

[0016] The flexible ear cap in the earphone wearing comfort detection device of the present invention can, under pressure in the ear canal, cause the pressure-sensitive layer on the inner surface of the cap to contact the electrode layer on the surface of the ear column, thereby causing a change in the output resistance information, so as to realize active ear pressure detection of the flexible earplug. Therefore, when the user wears the flexible earplug, he / she can obtain ear pressure feedback in real time, thereby adjusting the depth and position of wearing the flexible earplug, and thus adjusting the wearing comfort.

[0017] Furthermore, this invention presents a novel method for detecting headphone wearing comfort based on a headphone wearing comfort detection device. Specifically, this invention obtains the initial wearing comfort pressure standard values ​​for different users, thereby achieving targeted detection of headphone wearing comfort, offering high flexibility and ease of operation. Simultaneously, this invention also obtains the wearing duration standard values ​​for different users, facilitating the alerting of users when their ear canals experience discomfort upon reaching the standard wearing time.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0025] See Figure 1 , Figure 1 The specific structure of the headphone wearing comfort detection device of the present invention is shown. It includes a flexible earplug, an electrode layer 1, a pressure-sensitive layer 2, and a processor. The flexible earplug includes an ear stump portion 3 and a flexible ear cap portion 4 connected to each other. The surface of the flexible ear cap portion 4 that contacts the inner wall of the ear canal is the outer cap surface, and the surface that contacts the ear stump portion 3 is the inner cap surface. The electrode layer 1 is disposed on the surface of the ear stump portion 3, and the pressure-sensitive layer 2 is disposed on the inner cap surface of the flexible ear cap portion 4. When the pressure-sensitive layer 2 and the electrode layer 1 are in contact, a resistance signal can be generated according to the real-time contact state. The electrode layer 1 is electrically connected to the processor and is used to send the resistance signal to the processor. The processor is used to generate pressure information based on the resistance signal.

[0026] When the earphone is worn using the comfort detection device, the flexible ear cap 4 of the flexible earbud is pressed in the ear canal, causing the pressure-sensitive layer 2 on its inner cap surface to contact the electrode layer 1 on the surface of the ear column 3, thereby causing a change in the output resistance information. The greater the pressure in the ear canal, the smaller the output resistance information; correspondingly, the processor calculates the corresponding pressure information based on the change in resistance.

[0027] like Figure 2 As shown, the smaller the value of the resistance signal R, the larger the value of the pressure information F.

[0028] Furthermore, the processor is also used to generate and output comfort level reminders based on the pressure information. It should be noted that different comfort levels can be set based on the magnitude of the pressure information, thereby outputting the headphone's wearing comfort level.

[0029] Preferably, the electrode layer 1 and / or pressure-sensitive layer 2 are integrated onto the flexible earplug using 3D printing. It should be noted that this invention integrates the electrode layer 1 and pressure-sensitive layer 2 onto the flexible earplug without altering its structure. Therefore, this invention does not change the original wearing method of the flexible earplug, while simultaneously providing feedback on ear pressure to the user and suggesting that the user adjust the flexible earplug to a suitable ear pressure, thereby improving the user's comfort during extended earphone wear.

[0030] In summary, this invention achieves active ear pressure detection for flexible earplugs, providing real-time feedback on ear pressure while the user wears the earplugs. This feedback allows for adjustment of the earplug's depth and position, thereby improving wearing comfort. Furthermore, this invention features a simple manufacturing process, allows for customization, lower costs, and has a wide range of applications.

[0031] See Figure 3 , Figure 3 A first embodiment of the headphone wearing comfort detection method of the present invention is shown, comprising:

[0032] S101, which places the headphone wearing comfort detection device inside the user's ear canal;

[0033] When wearing the headphone comfort detection device, the flexible ear cap with a pressure-sensitive layer needs to be inserted into the user's ear canal. At this time, under the pressure of the ear canal, the pressure-sensitive layer on the inner surface of the flexible ear cap comes into contact with the electrode layer on the surface of the ear column, thereby causing a change in the output resistance signal.

[0034] S102, Adjust the real-time position of the headphone wearing comfort detection device in the ear canal until the user feels discomfort in the ear canal;

[0035] S103: When the user feels discomfort in the ear canal, the pressure information detected by the headphone wearing comfort detection device is obtained, and the pressure information is used as the user's initial wearing comfort pressure standard value.

[0036] Therefore, through steps S101-S103, the initial wearing comfort pressure standard value of different users can be obtained, thereby realizing targeted testing of headphone wearing comfort, which is highly flexible and easy to operate.

[0037] Accordingly, flexible earplugs can be customized for users based on the initial wearing comfort pressure standard value, which is highly targeted and can effectively improve the user's wearing comfort.

[0038] See Figure 4 , Figure 4 A second embodiment of the headphone wearing comfort detection method of the present invention is shown, comprising:

[0039] S201, which places the headphone wearing comfort detection device inside the user's ear canal;

[0040] S202, Adjust the real-time position of the headphone wearing comfort detection device in the ear canal until the user feels discomfort in the ear canal;

[0041] S203: When the user feels discomfort in the ear canal, the pressure information detected by the headphone wearing comfort detection device is obtained, and the pressure information is used as the user's initial wearing comfort pressure standard value.

[0042] S204: Real-time acquisition of pressure information detected by the headphone wearing comfort detection device;

[0043] S205 compares the pressure information with the initial wearing comfort pressure standard value;

[0044] S206 When the pressure information is greater than or equal to the initial wearing comfort pressure standard value, a comfort reminder message is generated to remind the user that the ear canal will be uncomfortable.

[0045] Specifically, the system can use mobile phone, earphone voice, earphone vibration and other reminder functions to remind the user that their ear canal will be in an uncomfortable state.

[0046] Therefore, in the initial stage of wearing the headphones, by acquiring the pressure information of the inner wall of the ear canal, when the pressure information is greater than or equal to the initial wearing comfort pressure standard value, the user can adjust the wearing depth of the earplugs to be shallower according to the reminder information so that the pressure information is within the initial wearing comfort pressure standard value range.

[0047] See Figure 5 , Figure 5 The third embodiment of the headphone wearing comfort detection method of the present invention is shown, including:

[0048] The S301 incorporates a headphone comfort testing device worn inside the user's ear canal.

[0049] S302, adjust the real-time position of the headphone wearing comfort detection device in the ear canal until the user feels discomfort in the ear canal;

[0050] S303: When a user feels discomfort in their ear canal, it acquires the pressure information detected by the headphone wearing comfort detection device and uses the pressure information as the user's initial wearing comfort pressure standard value.

[0051] S304, Adjust the real-time position of the headphone wearing comfort detection device in the ear canal so that the pressure information detected by the headphone wearing comfort detection device is less than the initial wearing comfort pressure standard value;

[0052] S305: When the user feels discomfort in the ear canal again, it obtains pressure information detected by the headphone wearing comfort detection device.

[0053] Adjust the real-time position of the headphone comfort detection device in the ear canal so that the pressure information detected by the headphone comfort detection device is less than the initial comfort pressure standard value. Continue wearing the headphone comfort detection device until the user feels discomfort in the ear canal again.

[0054] S306 records the duration of wear when the user feels discomfort in the ear canal again.

[0055] When the user wears the flexible earplugs, the processor is connected to the flexible earplugs. By adjusting the position of the flexible earplugs, the pressure information detected by the processor can be adjusted to be less than or equal to the pressure information detected in step S305. That is, when the user wears the flexible earplugs within the wearing time information recorded in step S306, the user is in a comfortable state.

[0056] See Figure 6 , Figure 6 A fourth embodiment of the headphone wearing comfort detection method of the present invention is shown, comprising:

[0057] S401, which places the headphone wearing comfort detection device inside the user's ear canal;

[0058] S402, adjust the real-time position of the headphone comfort detection device in the ear canal until the user feels discomfort in the ear canal;

[0059] S403: When the user feels discomfort in the ear canal, it acquires the pressure information detected by the headphone wearing comfort detection device and uses the pressure information as the user's initial wearing comfort pressure standard value.

[0060] S404, Adjust the real-time position of the headphone wearing comfort detection device in the ear canal so that the pressure information detected by the headphone wearing comfort detection device is less than the initial wearing comfort pressure standard value;

[0061] S405: When the user feels discomfort in the ear canal again, it acquires pressure information detected by the headphone wearing comfort detection device.

[0062] S406 records the duration of wear when the user feels discomfort in the ear canal again.

[0063] S407, set the standard value for wearing duration based on wearing duration information;

[0064] Among them, the standard value for wearing duration is less than the wearing duration information;

[0065] S408 can detect the user's headphone wearing time in real time;

[0066] S409 compares the earphone wearing time with the preset standard wearing time value;

[0067] The S410 generates a comfort reminder message when the earphone wearing time equals the standard wearing time value to alert the user that the ear canal will feel uncomfortable.

[0068] Specifically, the system can use reminders via mobile phone, earphone voice, and earphone vibration to alert the user when the earphone wearing time reaches the standard value, indicating that the ear canal will feel uncomfortable.

[0069] In summary, this invention achieves active ear pressure detection for flexible earplugs, which can obtain real-time ear pressure feedback when the user wears the flexible earplugs, thereby adjusting the depth and position of the flexible earplugs and thus adjusting the wearing comfort.

[0070] The above description represents the preferred embodiments of the present invention.
