Description

Technical Field

[0001] The invention relates to the technical field of open-type earphones, and in particular to a method for testing the wearing stability of an OWS earphone. Background Art

[0002] Open-type OWS headphones, as the name implies, are open-type headphones that are not worn in the ears and do not block or cover the ears. Compared with traditional closed or semi-closed headphones, open-type headphones have excellent comfort and open listening effects, and therefore have become the hottest headphone products. Today's open-type headphone designs pay much attention to appearance. Everyone likes beautiful things, and wearing headphones is more like wearing a decoration, and you don't have to think about matching. OWS headphones have a unique design, and are generally designed with ear hooks or ear clips.

[0003] Advantages of OWS earphones: The ear canal can be kept open during the entire use process, ensuring sufficient air circulation inside the ear. In-ear earphones require the earplug to be inserted into the ear canal during wearing, which creates a strong sense of pressure. The ear canal cannot maintain air circulation during wearing, which can lead to the growth of bacteria in the ear canal and even cause diseases such as otitis media. Therefore, OWS earphones are safer than in-ear earphones. In addition, whether the earhook type is hung on the ear wheel or the ear clip type is clipped on the edge of the ear, it is not easy to slip off during exercise.

[0004] Disadvantages of OWS headphones: Due to the open design of the open ear canal, there will be sound leakage, external sound will be played, and there is a lack of privacy. Most importantly, in terms of sound quality, OWS headphones are inferior to in-ear headphones. Due to the leakage caused by wearing, the low-frequency part of the music is missing.

[0005] In particular, there is a certain instability in listening to music when wearing OWS headphones. Unlike in-ear headphones, which can rely on the ear cap to be inserted into the ear canal to locate the sound propagation channel, after wearing OWS, you must pay special attention to adjusting the angle and position of the headphones to ensure that the sound outlet of the headphones faces the ear canal to obtain the best listening effect possible.

[0006] Currently in the industry, acoustic engineers can usually only judge the degree to which headphones can receive music subjectively during the prototype stage, simply by playing music after wearing them and listening with their own ears. However, this method of relying solely on subjective listening verification by human ears has a high probability of misjudgment, and also lacks sufficient objective data for analysis.

[0007] In addition, whether the design of OWS headphones can meet the wearing requirements of most potential customers also requires systematic testing and analysis, and more detailed data to draw more correct conclusions.

[0008] Therefore, it is extremely important and imperative to use the correct methods and tests, conduct sufficient verification in the early stages of product design, and discover problems in advance, which will be more conducive to the correction of the entire product before mold opening and mass production.

[0009] Therefore, it is necessary to provide a technical solution that can improve the clamping stability and service life of the earphone. Summary of the invention

[0010] The present invention provides a method for testing the wearing stability of an OWS headset, so as to solve the problem that the existing method of verifying the wearing stability of an OWS headset by relying solely on subjective listening of human ears has misjudgment and lacks sufficient objective data for analysis.

[0011] The technical solution adopted by the present invention is as follows: A method for testing the wearing stability of an OWS headset comprises the following steps:

[0012] Step 1: Use a simulated human head to test the acoustic wearing consistency of the earphone, including the following steps:

[0013] (1.1) Building a first test system device in an acoustic anechoic room, wherein the first test system device includes a first acoustic test system, a first sound card, a first Bluetooth Dongle, a first power supply, and a simulated human head, wherein the first sound card and the first Bluetooth Dongle are both connected to the first acoustic test system, the first power supply is connected to the first sound card, and the simulated human head is connected to the first power supply;

[0014] (1.2) Wearing the OWS headset on the artificial ear of the simulated human head, turning on the Bluetooth mode, and using the first Bluetooth Dongle to establish a Bluetooth connection between the first acoustic test system and the OWS headset;

[0015] (1.3) Setting parameters in the first acoustic test system and playing the signal required for the test to transmit it to the speaker in the OWS headset, so that the speaker makes a sound;

[0016] (1.4) The microphone in the artificial ear of the simulated human head receives the audio signal, which is input into the first acoustic test system through the first power supply and the first sound card to generate a first acoustic frequency response curve, which is regarded as the first test curve. Multiple tests are performed according to different wearing methods of the OWS headset;

[0017] (1.5) Collect test comparison curves to evaluate the wearing stability of OWS headphones;

[0018] Step 2: Use real-person test big data for analysis: A standard simulated human head can represent the head features of most people and serve as an objective reference for the initial test of OWS headset wearing. If the initial test results are OK, the next step is to conduct test verification of real-person wearing big data collection. If the actual test is not ideal, R&D needs to optimize the structure until the expected effect is achieved. The real-person test includes the following steps:

[0019] (2.1) Wear the microphone receiving system as a normal in-ear headset and insert it into the ear canal of the human ear. Lead out the lead of the microphone receiving system, connect it to the microphone terminal box in a conventional manner, and then connect it to the second power supply and the second sound card in sequence to form a test receiving loop, so that the microphone receiving system functions similarly to a microphone simulating a human head;

[0020] (2.2) In an acoustic anechoic room, a second test system device is set up, wherein the second test system device includes a second acoustic test system, a second sound card, a second Bluetooth Dongle, a second power supply and a microphone connection box, wherein the second sound card and the second Bluetooth Dongle are both connected to the second acoustic test system, the second power supply is connected to the second sound card, the microphone connection box is connected to the second power supply, and the microphone receiving system is connected to the microphone connection box;

[0021] (2.3) Wearing the OWS headset on the human ear, turning on the Bluetooth mode, and using the second Bluetooth Dongle to establish a Bluetooth connection between the second acoustic test system and the OWS headset;

[0022] (2.4) Setting parameters in the second acoustic test system and playing the signal required for the test to transmit it to the speaker in the OWS headset, so that the speaker makes a sound;

[0023] (2.5) The microphone receiving system in the human ear receives the audio signal, passes through the microphone junction box, the second power supply, the second sound card, and then is input into the second acoustic test system to generate a second acoustic frequency response curve, which is regarded as the second test curve;

[0024] (2.6) Big data collection test: Multiple batches of real people are used for testing, and each person and each model of OWS headset is tested in multiple wearing methods.

[0025] In one embodiment, the first acoustic test system and the second acoustic test system are both Soundcheck acoustic test systems, which are both composed of a computer host and a display, and the display is connected to the computer host.

[0026] In one implementation, the parameters in step (1.3) are set to a normal -10dBFS output and to play a 1 / 12Oct sine wave signal.

[0027] In one implementation, the parameters in step (2.4) are set to a normal -10dBFS output and to play a 1 / 12Oct sine wave signal.

[0029] In one embodiment, there are three wearing methods in step (2.6), namely normal wearing, wearing from below and wearing from above.

[0030] In one embodiment, the manufacturing method of the microphone receiving system is as follows:

[0031] ①Use the earphone shell of in-ear earphones and keep the sound outlet part;

[0032] ② Take a small microphone and solder the two leads to the two soldering points of the small microphone respectively.

[0033] ③ With the sound pickup surface of the small-volume microphone facing outward, the small-volume microphone is fixed in the earphone shell by using glue, and the lead wire is led out from the pipe of the sound outlet;

[0034] ④ Fit the sound outlet onto the outer surface of the earphone shell, and then put on the ear cap.

[0035] In one implementation, the small-volume microphone is a Φ4*1.5 mm condenser microphone.

[0036] In one embodiment, the length of the lead wire is greater than 0.5 m.

[0037] In one implementation, the small-volume microphone is an omnidirectional microphone.

[0038] The beneficial effects of the present invention are:

[0039] In the present application, by using a simulated human head to test the acoustic wearing consistency of the earphones, and cooperating with the analysis of real-person test big data, it is possible to compare the stability of various appearance designs after wearing in advance in the initial prototype stage of OWS earphone design, that is, to verify the optimal ID and structural design in advance, that is, to be able to physically meet the ergonomic wearing requirements and the best sound quality requirements; curve test comparison is more standardized and more powerful to verify the feasibility of structural parts for acoustics, which can play a role in early prevention and error correction.

[0057] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0058] To facilitate understanding by those skilled in the art, the present application describes the specific implementation process of the technical solution in the present application through the following embodiments.

[0059] See also Figure 1 - Fig.15 A method for testing the wearing stability of an OWS headset of this embodiment includes the following steps:

[0060] Step 1: Use a simulated human head to test the acoustic wearing consistency of the earphone, including the following steps:

[0061] (1.1) A first test system device 20 is set up in the acoustic anechoic chamber 10, such as Figure 4 As shown, the first test system device 20 includes a first acoustic test system 21, a first sound card 22, a first Bluetooth Dongle 23, a first power supply 24 and a simulated human head 25. The first sound card 22 and the first Bluetooth Dongle 23 are both connected to the first acoustic test system 21, the first power supply 24 is connected to the first sound card 22, and the simulated human head 25 is connected to the first power supply 24. In this embodiment, the first acoustic test system 21 is a Soundcheck acoustic test system, which is composed of a computer host 211 and a display 212. The display 212 is connected to the computer host 211, and the first sound card 22 and the first Bluetooth Dongle 23 are both connected to the computer host 211.

[0062] (1.2) Wear the OWS headset 30 on the artificial ear 251 of the simulated human head 25, turn on the Bluetooth mode, and use the first Bluetooth Dongle 23 to establish a Bluetooth connection between the first acoustic test system 21 and the OWS headset 30.

[0063] (1.3) Set parameters in the first acoustic test system 21, and play the signal required for the test to transmit it to the speaker in the OWS headset 30, so that the speaker makes a sound. In this embodiment, the parameters are set to a normal -10dBFS output, and a 1 / 12Oct sine wave signal is played.

[0064] (1.4) The microphone 252 in the artificial ear 251 of the simulated human head 25 receives the audio signal, which is input into the first acoustic test system 21 through the first power supply 24 and the first sound card 22, and a first acoustic frequency response curve is generated, which is regarded as the first test curve. Multiple tests are performed according to multiple different wearing methods of the OWS headset 30. The tests are performed according to three different wearing methods of the OWS headset 30, in order: normal wearing (the OWS headset 30 is close to the most stable wearing), downward wearing (the OWS headset 30 is worn at the lowest position), and upward wearing (the OWS headset 30 is worn at the highest position), wherein downward wearing and upward wearing simulate the most extreme wearing conditions.

[0065] (1.5) Collect test comparison curves to evaluate the wearing stability of the OWS headset 30.

[0066] like Fig.12 and Fig.13As shown in the figure, two OWS headphones 30 (type A and type B) are used as examples to demonstrate the test curve comparison using the simulated human head 25. The greatest impact on wearing instability is mainly concentrated in the low-frequency area. Taking 100 Hz as the reference frequency point of this test scheme, the test results of the three wearing methods show that the curve dispersion of type A is controlled within 5 dB, while that of type B is within 7 dB. It can be determined that the wearing stability of type A is stronger than that of type B through the simulated human head test comparison.

[0067] The above data, combined with the subjective wearing and listening judgment of acoustic engineers, preliminarily define: OWS headphones 30 initially use three types of wearing tests on simulated human heads 25, with 100Hz frequency as the reference point, and the sensitivity dispersion should be controlled within 5dB.

[0068] Step 2: Use real person test big data for analysis: A standard simulated human head 25 can represent the head features of most people and serve as an objective reference for the initial test of the OWS headset 30. If the initial test result is OK, the next step is to enter the test verification of real person wearing big data collection. If the actual test is not ideal, R&D needs to optimize the structure until the expected effect is achieved. The real person test includes the following steps:

[0069] (2.1) The microphone receiving system 40 is worn as a normal in-ear headset and inserted into the ear canal of the human ear 50. The lead 41 of the microphone receiving system 40 is led out, and the lead 41 is connected to the microphone terminal box 65 in a conventional manner, and then connected to the second power supply 64 and the second sound card 62 in sequence to form a test receiving circuit, so that the microphone receiving system 40 functions similarly to the microphone 252 of the simulated human head 25, as shown in FIG. Figures 9 to 11 shown.

[0070] There is a bottleneck problem in the real person test. The tester can hear the sound by wearing the OWS headset 30, but cannot transmit the audio signal to the device like the microphone 252 of the simulated human head 25 to form a frequency response curve. Therefore, a microphone receiving system 40 is specially designed, such as Figure 8 As shown, the method for making the microphone receiving system 40 is as follows:

[0071] ① Use an earphone shell 42 of an in-ear earphone and retain a sound outlet 421.

[0072] ② Take the small microphone 43, and weld the two leads 41 to the two welding points of the small microphone 43. In this embodiment, the small microphone 43 is a Φ4*1.5mm capacitive microphone, and the length of the lead 41 is more than 0.5m, which is convenient for subsequent operations. In addition, the small microphone 43 is an omnidirectional microphone, so no matter which direction the microphone points to the sound source, it will not affect the normal sound pickup effect.

[0073] ③ Place the sound pickup surface of the small-volume microphone 43 facing outwards, and fix the small-volume microphone 43 in the earphone shell 42 by using glue dispensing, and lead wire 41 is led out from the pipe of the sound outlet 421.

[0074] ④ Place the sound outlet 421 on the outer surface of the earphone shell 42, and then put on the ear cap 44.

[0075] Furthermore, the length of the entire microphone receiving system 40 is controlled within 15 mm to avoid interference when the OWS headset 30 is subsequently worn.

[0076] (2.2) In the acoustic anechoic chamber 10, a second test system device 60 is set up, such as Figure 7 As shown, the second test system device 60 includes a second acoustic test system 61, a second sound card 62, a second Bluetooth Dongle 63, a second power supply 64 and a microphone connection box 65. The second sound card 62 and the second Bluetooth Dongle 63 are both connected to the second acoustic test system 61, the second power supply 64 is connected to the second sound card 62, the microphone connection box 65 is connected to the second power supply 64, and the microphone receiving system 40 is connected to the microphone connection box 65. In this embodiment, the second acoustic test system 61 is a Soundcheck acoustic test system, which is composed of a computer host 611 and a display 612. The display 612 is connected to the computer host 611, and the second sound card 62 and the second Bluetooth Dongle 63 are both connected to the computer host 611.

[0077] (2.3) Wear the OWS headset 30 on the human ear 50, turn on the Bluetooth mode, and use the second Bluetooth Dongle 63 to establish a Bluetooth connection between the second acoustic test system 61 and the OWS headset 30.

[0078] (2.4) Set parameters in the second acoustic test system 61, and play the signal required for the test to transmit it to the speaker in the OWS headset 30, so that the speaker makes a sound. In this embodiment, the parameters are set to a normal -10dBFS output, and a 1 / 12Oct sine wave signal is played.

[0079] (2.5) The microphone receiving system 40 in the human ear 50 receives the audio signal, which is input into the second acoustic test system 61 through the microphone connection box 65, the second power supply 64, and the second sound card 62, thereby generating a second acoustic frequency response curve, which is regarded as the second test curve.

[0080] (2.6) Big data collection test: multiple batches of tests are conducted using real people, and each person and each model of OWS headset 30 are also tested in multiple wearing methods. In this embodiment, there are three wearing methods, namely normal wearing, wearing from below, and wearing from above. In theory, the more people there are, the more comprehensive the data will be, and the more accurate and objective the analysis will be. Generally, it is necessary to reserve some people with obvious ear defects, that is, people who are more likely to become unstable when wearing, as key test reference objects. In this embodiment, a group of 30 people is used, including 20 ordinary people and 10 people with defects. The test results are as follows: Fig.14 and Fig.15 As shown, Fig.14 and Fig.15 There are two types of OWS headphones 30, A and B, each using test curve big data of 30 people in three wearing methods. Taking 100Hz frequency as the reference point, the curve dispersion of type A is controlled within 20dB, while that of type B is within 24dB. It can be judged that the wearing stability of type A is still stronger than that of type B through actual wearing test comparison with real people.

[0081] In a subjective wearing and listening test of 30 people, the feedback of Type A OWS earphone 30 is that wearing the earphone will not obviously affect the appreciation of music. Therefore, it is defined that: OWS earphone 30 adopts three wearing tests of real people, with 100Hz frequency as the reference point, and the dispersion of sensitivity should be controlled within 20dB. Moreover, in theory, the smaller the dispersion of the curve, the more stable the OWS earphone 30 is to wear, which is the direction to continue our efforts.

[0082] In summary, the new test method of OWS headphone 30 can effectively discover the instability problems caused by wearing in the early stage of headphone design, and can test the objective curve as a theoretical basis. It can become a complete and feasible test judgment standard for improving the product.

[0083] Compared with the prior art: In the present application, by using a simulated human head to test the acoustic wearing consistency of headphones, and cooperating with the use of real-person test big data for analysis, the stability of various appearance designs after wearing can be compared in advance in the initial prototype stage of OWS headphone design, that is, the optimal ID and structural design can be verified in advance, that is, it can be physically ergonomically worn and meet the requirements of the best sound quality; curve test comparison is more standardized and more powerful to verify the feasibility of structural parts for acoustics, which can play a role in early prevention and error correction. Otherwise, once the product is put on the market, it will receive negative feedback from consumers; the present invention has a wide range of applications, is simple and effective, and can basically be applied to all OWS headphones currently on the market, and even various types of headphones with sound leakage for acoustic wearing detection.

[0084] As long as it does not violate the creative ideas of the present invention, any combination of the various embodiments of the present invention shall be regarded as the contents disclosed by the present invention; within the technical concept of the present invention, any combination of various simple modifications of the technical scheme and different embodiments that does not violate the creative ideas of the present invention shall be within the protection scope of the present invention.
