Description

Technical Field

[0001] This application relates to the field of headphone technology, and in particular to an open-back headphone and its wearing method. Background Technology

[0002] Headphones have become an indispensable part of modern life, playing an important role in daily commutes, exercise, work, study, and entertainment. Currently, there are many different types of headphones on the market. Based on the communication method between the headphones and the terminal device, they can be divided into wired and wireless headphones; based on the wearing style, they can be divided into in-ear headphones, semi-in-ear headphones, open-back headphones, over-ear headphones, and ear-hook headphones, etc.

[0003] Different types of headphones have different characteristics. Specifically, wired headphones connect to devices via electrical cables, offering more stable sound quality, lower latency, less susceptibility to wireless signal interference, and relatively lower prices. However, the cables are prone to tangling, causing considerable inconvenience in practical use.

[0004] Wireless headphones primarily connect to devices via Bluetooth, Wi-Fi, or other wireless technologies. They are portable and eliminate the inconvenience of connecting cables. However, the stability of wireless connections is relatively poor compared to wired headphones, with latency issues. Sound quality is also affected by the wireless connection, and battery life is limited.

[0005] In-ear headphones are inserted into the user's ear canal during use, offering good sound isolation and being small and lightweight. However, because they are inserted into the ear canal, they can compress the ear canal to some extent, causing discomfort. Furthermore, the closed-back design of in-ear headphones can lead to greater pressure within the ear, potentially damaging hearing, and can also create a relatively moist environment in the ear canal, promoting bacterial growth and potentially damaging the ear canal skin. In some cases, the sound-producing part of the in-ear headphone is almost completely inserted into the ear canal, providing a high degree of isolation from external sounds, which can increase the risk of accidents in certain situations.

[0006] Semi-in-ear headphones are not fully inserted into the ear canal during use. In recent years, semi-in-ear headphones have become popular due to their relatively higher wearing comfort compared to in-ear headphones. However, semi-in-ear headphones also have some potential risks. For example, even with semi-in-ear headphones, prolonged use can still lead to hearing damage and ear canal bacterial growth. In addition, semi-in-ear headphones have relatively poor sound isolation; and their wearing stability is poor, making them prone to falling out during vigorous exercise.

[0007] Open-back headphones are not inserted into the ear canal during use. Existing open-back headphones primarily transmit sound via bone conduction. Typically, existing bone conduction open-back headphones have two parts located on either side of the head, corresponding to the temporal bones on either side. At least one of these parts contains a vibrating component. Furthermore, to keep the vibrating component at the temporal bone, existing bone conduction open-back headphones also include a headphone support connecting the two parts, with the headphone support worn at the back of the head.

[0008] The current design of bone conduction open-back headphones makes their overall structure quite challenging. For example, they require two separate sections positioned on either side of the head for secure clamping via a headband; the weight distribution of these two sections needs to be carefully controlled to maintain balance and prevent excessive pressure on one side of the head; and the headband's shape, weight, and materials require specific design considerations to maintain balance, reduce pressure on the head and neck, and prevent skin irritation or damage from repeated friction. Furthermore, existing bone conduction open-back headphones rely on clamping the head to maintain a close fit to the temporal bones. However, even with meticulous design of the two sections and the headband, slippage or detachment is still possible. Users often need to repeatedly adjust the wearing angle to improve stability and balance comfort. Furthermore, the temporal bone region is quite sensitive. Existing bone conduction open-back headphones primarily rely on clamping the head to hold it firmly against the temporal bones. Prolonged wear can cause prolonged pressure on the temporal bone region, leading to pain. Additionally, existing bone conduction open-back headphones are relatively bulky and heavy, affecting their portability.

[0009] Existing non-bone conduction open-back headphones primarily place the sound-emitting part of the headphone inside the concha of the ear to avoid blocking the external auditory canal. However, placing the sound-emitting part inside the concha can easily lead to sound leakage. Furthermore, placing the sound-emitting part inside the concha makes the headphones prone to falling out. To ensure wearing stability, some existing non-bone conduction open-back headphones typically clamp the ear tightly to the user's ear, which can easily cause ear pain. Additionally, the relatively large size of the sound-emitting part, when in close contact with the skin inside the concha for extended periods, can result in a large area of ​​skin friction, leading to localized stuffiness and dampness.

[0010] Over-ear headphones completely cover the ears during use, offering good sound quality and noise isolation, delivering a powerful and immersive audio experience. However, their large size makes them inconvenient to carry and store, and they require more power to operate. Furthermore, their strong noise isolation can prevent users from hearing external sounds, potentially leading to accidents.

[0011] Compared to over-ear headphones, ear-hook headphones offer advantages such as better stability, greater privacy, affordability, and adjustable noise isolation. However, they also have disadvantages, including lower comfort, inferior sound quality, and less effective noise cancellation compared to over-ear headphones. Furthermore, ear-hook headphones can interfere with the wearing of other accessories, such as hearing aids and other earrings. Summary of the Invention

[0012] One advantage of this application is that it provides an open-back headphone and a method for wearing it, wherein the open-back headphone can not only transmit sound to the user's ear through the sound tube, but also stably wear the open-back headphone with the sound transmitted through the sound tube to the user's ear.

[0013] Another advantage of this application is that it provides an open-back headphone and a method of wearing it, wherein the main body of the open-back headphone for sound production can be worn behind the user's ear, which can make the open-back headphone "invisible" to a certain extent and not easily seen by others.

[0014] Another advantage of this application is that it provides an open-back headphone and a method for wearing it. The sound tube of the open-back headphone does not require any other components to be arranged inside, allowing for a reduction in radial dimensions. On the one hand, it does not completely block the ear canal opening, achieving open-back sound production, which reduces hearing damage to some extent and lowers the risk of use due to poor reception of external sounds, thus improving wearing safety. On the other hand, it minimizes pressure on the ear canal, improving wearing comfort and reducing the contact area with the user's ear canal skin, thus reducing the risk of ear canal infection. Furthermore, it improves the concealment of the open-back headphone to some extent.

[0015] Another advantage of this application is that it provides an open-back headphone and a method for wearing it. The sound tube of the open-back headphone can be used to stably wear the headphone with sound transmission through the sound tube in conjunction with the concave and convex structure of the user's external auditory canal and the shape of the sound tube. Compared with the method of mainly clamping the user's ear tightly, this application can stably wear the open-back headphone with sound transmission through the sound tube in the user's ear while reducing the clamping force on the user's ear to a certain extent, thereby improving wearing comfort, reducing the contact area with the user's external auditory canal skin, and reducing the risk of ear canal infection.

[0016] Another advantage of this application is that it provides an open-back headphone and a method of wearing it, wherein no other components need to be arranged inside the open-back headphone, which makes the design of the sound guide tube of the open-back headphone with sound transmission tube more flexible.

[0017] Another advantage of this application is that it provides an open-back headphone, wherein, in some embodiments, the open-back headphone can be equipped with a hearing aid unit, so that the open-back headphone is compatible with hearing aid functions. In this way, the problem of users with hearing impairments being unable to wear hearing aids when wearing headphones can be avoided.

[0018] Another advantage of this application is that it provides an open-back headset, which integrates an artificial intelligence module to improve its interactivity with terminal devices and users. For example, by interacting with terminal devices, it can not only control the playback of audio and video and make phone calls, but also provide users with network information, conduct online shopping, send emails, and control home or office devices.

It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or combinations thereof.

[0045] For ease of explanation, in the embodiments of this application, the ear surface facing the external auditory canal of the user's ear E is defined as the front, and the ear surface facing away from the external auditory canal is defined as the back.

[0046] Refer to the accompanying drawings in this application specification. Figures 1 to 6As shown, the open-back earphone 1 according to an embodiment of the present invention will be explained in the following description. In this embodiment, the open-back earphone 1 can not only transmit sound to the user's ear E through the sound guide tube 20, but also be worn relatively stably to the user's ear E through the sound guide tube 20. Accordingly, the open-back earphone 1 includes a main body 10 and at least one sound guide tube 20. The main body 10 is mainly used for sound generation. The sound guide tube 20 is connected to the main body 10. The sound guide tube 20 can not only conduct sound, but also cooperate with the main body 10 to place the ear E between the main body 10 and the sound guide tube 20, and can be worn relatively stably to the user's ear E even when the main body 10 and the sound guide tube 20 are not clamping the user's ear E.

[0047] To facilitate the description of the structure of the open-back headphone 1, as follows: Figure 1 and Figure 2 As shown, this application defines the main body 10 with two opposite sides, a first side 104 and a second side 105, on a first direction D1, and two opposite sides, an upper side 106 and a lower side 107, on a second direction D2; and two opposite sides, a front side 108 and a rear side 109, on a third direction D3, i.e., in the thickness direction. The first direction D1 is perpendicular to the thickness direction of the main body 10; the second direction D2 is perpendicular to both the first direction D1 and the second direction D2. The first direction D1 is consistent with the width direction of the user's ear E when the open-back headphones 1 are worn on the user's ear E. The second direction D2 is consistent with the length direction of the user's ear E when the open-back headphones 1 are worn on the user's ear E. The third direction D3 is consistent with the thickness direction of the user's ear E when the open-back headphones 1 are worn on the user's ear E. The main body 10 has a front side 102 and a rear side 103 on the third direction D3.

[0048] Specifically, such as Figure 4 As shown, the main body 10 includes a mounting housing 11, a battery 14, and a circuit board 13. The sound-generating unit 12, the battery 14, and the circuit board 13 are centrally arranged within the same mounting housing 11, making the internal structure of the main body 10 of the open-back headphone 1 more compact, thereby reducing the overall size of the main body 10 of the open-back headphone 1 and making the open-back headphone 1 more compact and portable.

[0049] like Figure 3As shown, when the main body 10 of the open-back earphone 1 is worn on the user's ear E, the main body 10 is worn on the back of the user's ear E, which can make the open-back earphone 1 "invisible" to a certain extent, making it difficult for others to see. In the thickness direction of the main body 10, the front side 102 of the main body 10 is close to the back of the user's ear E, and the rear side 103 of the main body 10 is away from the back of the user's ear E. More specifically, the main body 10 can be worn on the back of the earlobe E1 of the user's ear E. It should be understood that the main body 10 can also be worn on the back of other positions of the user's ear E.

[0050] The mounting housing 11 can be integrally formed or formed by combining at least two parts. For example... Figure 4 As shown in one example of this application, the mounting housing 11 includes a first housing portion 111 and a second housing portion 112. The first housing portion 111 and the second housing portion are engaged and enclose a mounting cavity 101 located between the first housing portion 111 and the second housing portion 112. In other words, the mounting housing 11 has a mounting cavity 101; the mounting cavity 101 is formed between the first housing portion 111 and the second housing portion 112. The mounting cavity 101 is used to accommodate components such as the battery 14, the sound-generating unit 12, and the circuit board 13. In this example, the first housing portion 111 is hemispherical in shape, and the second housing portion 112 is cylindrical in shape. It should be understood that the shapes of the first housing portion 111 and the second housing portion 112 can be designed in other forms. The front side 102 of the main body portion 10 is formed in the second housing portion 112; the rear side 103 of the main body portion 10 is formed in the first housing portion 111.

[0051] The first housing portion 111 and the second housing portion 112 may be made of the same or different materials. In one example of this application, the first housing portion 111 is made of a non-metallic material, and the second housing portion 112 is made of a metallic material.

[0052] The sound-emitting unit 12 is installed within the mounting cavity 101. The sound-emitting unit 12 may be implemented as a loudspeaker. In one example of this application, the sound-emitting unit 12 is located near the front side 102 of the main body 10, close to the user's ear E.

[0053] The main body 10 also includes at least one charging contact 30. The charging contact 30 is disposed on the circuit board 13 to facilitate charging. When the charging contact 30 contacts the conductive structure (e.g., a pin) of the charging plate of the earphone charging case, the open-back earphone 1 can be charged.

[0054] In one embodiment of this application, the main body 10 further includes an operating component for user operation to adjust the state of the open-back earphone 1, enabling operations such as volume adjustment, channel switching, power on / off, and answering calls. The operating component is connected to the circuit board 13. Specifically, different adjustments can be achieved by controlling the operation time and number of operations of the operating component. By operating the operating component, the user transmits signals to the circuit board 13, which then processes the signals and issues commands through the signal processing unit of the circuit board 13, thereby achieving different functional adjustments.

[0055] The operating element can be implemented as a push-button or as other types of operating elements, such as a joystick or a touch-sensitive operating element.

[0056] It is understood that the circuit board 13 of the open-back headset 1 may integrate a communication module and a microphone. The communication module may be a Bluetooth module, a Wi-Fi module, etc., used for communicatively connecting with a terminal device. The microphone is used to collect the user's voice commands and external sounds, and transmit them to the communication module. Optionally, the circuit board 13 may further integrate an intelligent analysis module, such as an artificial intelligence module, which can improve its interactivity with the terminal device and the user. For example, through interaction with the terminal device, it can not only control the playback of audio and video and make phone calls, but also provide the user with network information, conduct online shopping, send emails, and control home or office equipment.

[0057] For example, the open-back headset 1 can serve as a smart voice interaction terminal device. When a user wears the open-back headset 1 while driving a new energy vehicle, the user can issue a voice command to the headset 1 to "defog." Upon receiving the user's command, the communication module transmits the "defog" command to the vehicle's sensing system. Upon receiving the signal from the communication module, the vehicle automatically activates the defogging mode. Similarly, if the user issues a voice command to the headset 1 to "automatic parking," the communication module transmits the "automatic parking" command to the vehicle's sensing system. Upon receiving the signal from the communication module, the vehicle automatically enters automatic parking mode. It is understood that this voice interaction is only an example; the open-back headset 1 can also be more widely applied to various smart interaction scenarios in life and work, such as smart home control, smart office, smart calls, smart driving, and smart healthcare.

[0058] In other words, the open-back headphones 1 can function as an artificial intelligence assistant device, which can acquire commands in real time through audio, identify and process the collected information, provide feedback based on semantic results, and finally perform corresponding intelligent control tasks.

[0059] It is worth mentioning that the microphone can have built-in algorithms to have noise reduction capabilities. That is, when the microphone receives the user's voice commands, it can reduce the ambient noise, thereby enabling the microphone to obtain a purer version of the user's voice.

[0060] A hearing aid unit can also be integrated on the control circuit board 13. The hearing aid unit includes an amplifier, a receiver, and other structures. It can collect sound through the microphone and convert it into an electrical signal. The main controller performs noise reduction processing on the interfering noise signal. The amplifier is used to increase the strength of the electrical signal, and the receiver is used to output the electrical signal to the sound-generating unit 12, thereby allowing the user to "perceive" sound through the sound-generating unit 12. The main controller is integrated into the circuit board 13 and coordinates the output relationship between the hearing aid unit and the sound-generating unit 12 during the wearing of the open-back headphones 1.

[0061] Specifically, the open-back earphone 1 combines a hearing aid and an earphone, meaning it centralizes sound output and hearing aid functions. In other words, the open-back earphone 1 can both make and receive calls and assist the user in hearing speech, automatically switching between the two modes. When a call comes in, the circuit board 13 of the open-back earphone 1 processes the signal and connects to the phone via Bluetooth, switching to the call function. Normally, the open-back earphone 1 can be used as a hearing aid, making it convenient for users with hearing impairments. This avoids the space constraints caused by earphones and hearing aids sharing the ear canal, preventing a series of inconveniences. In other words, the open-back earphone 1 is compatible with hearing aid functions, thus avoiding the problem of users with hearing impairments being unable to wear hearing aids while wearing earphones.

[0062] The sound guide tube 20 is mainly used to transmit the sound signal emitted by the main body 10 to the user's ear E. The sound guide tube 20 has a first end 201 and a second end 202. The first end 201 of the sound guide tube 20 is connected to the main body 10; the second end 202 of the sound guide tube 20 is the movable end of the sound guide tube 20, and also the end of the sound guide tube 20.

[0063] The sound guide tube 20 is adapted to extend into the user's external auditory canal. It is hollow internally and has at least one sound guide channel 203, which connects the mounting cavity 101 to the outside. The sound guide channel 203 has a first connecting port 2031 and a second connecting port 2032. The first connecting port 2031 communicates with the mounting cavity 101 and is preferably adjacent to the sound-generating unit 12. The second connecting port 2032 is located outside the main body 10. The first connecting port 2031 and the second connecting port 2032 may be located at the first end 201 and the second end 202 of the sound guide tube 20, respectively. The second connecting port 2032 may also be located outside the second end 202 of the sound guide tube 20.

[0064] It is worth mentioning that, in one embodiment of this application, the open-back earphone 1 has an arc-shaped end face at the second end 202 of the sound guide tube 20. Accordingly, in this embodiment, the second end 202 of the sound guide tube 20 has an arc-shaped end face 2021 to prevent the portion entering the user's ear E from scratching the ear E. The end face 2021 has a through hole, and the through hole of the end face 2021 communicates with the guiding channel 203. In one example of this application, the guiding tube 20 includes a conduit body 2010 and a spherical structure 2020. One end of the conduit body 2010 forms the first end 201 of the guiding tube 20; the other end of the conduit body 2010 is connected to the spherical structure 2020. The end of the spherical structure 2020 forms the second end 202 of the sound guide tube 20. The catheter body 2010 has a first hollow channel 20101, and the spherical structure 2020 has a second hollow channel 20201. The first hollow channel 20101 of the catheter body 2010 and the second hollow channel 20201 of the spherical structure 2020 are connected. The first hollow channel 20101 and the second hollow channel 20201 form the sound guiding channel 203 of the sound guiding tube 20. The spherical structure 2020 is fixed to the catheter body 2010, detachably connected to the catheter body 2010, or movably connected to the catheter body 2010. When the spherical structure 2020 is fixed to the catheter body 2010, the spherical structure 2020 can be integrally formed with the catheter body 2010, or it can be separately connected to the catheter body 2010. The spherical structure 2020 can be a metal sphere.

[0065] The second end 202 of the sound guide tube 20 extends into the user's external auditory canal, ensuring privacy and sound quality during listening. Furthermore, its open design reduces the risk of hearing damage. When the second end 202 is equipped with the spherical structure 2020, the spherical structure 2020 (which can be implemented as a metal ball) of the sound guide tube 20 is secure and close to the ear canal, ensuring privacy and sound quality during listening and reducing hearing damage. The spherical structure 2020 (which can be implemented as a metal ball) of the sound guide tube 20 prevents the tube from puncturing the eardrum while also meeting aesthetic requirements.

[0066] It is also worth mentioning that the sound guide tube 20 of the open-back earphone 1 does not require other components to be arranged inside, and its radial dimension can be reduced. On the one hand, it does not completely block the ear canal opening, achieving open-back sound production, which reduces hearing damage to a certain extent and lowers the risk of use due to poor reception of external sounds. On the other hand, it minimizes pressure on the ear canal, improves wearing comfort, reduces the contact area with the user's ear canal skin, and reduces the risk of ear canal infection. Furthermore, it improves the concealment of the open-back earphone 1 to a certain extent. In one embodiment of this application, the outer diameter of the sound guide tube 20 is less than or equal to 10 mm. In another embodiment of this application, the outer diameter of the sound guide tube 20 is equal to 4 mm, and the inner diameter of the sound guide tube 20 is equal to 3 mm.

[0067] A sound-conducting tube 20 forms an ear-receiving space 120 between itself and the main body 10. The ear-receiving space 120 has an ear inlet 1201, allowing a user to insert at least a portion of their ear E into the ear-receiving space 120 through the ear inlet 1201. The sound-conducting tube 20 is movably connected to the main body 10, such that the dimensions of the ear-receiving space 120 and the ear inlet 1201 are adapted to change with relative movement between the sound-conducting tube 20 and the main body 10. This facilitates the wearing of the open-back headphones 1 and adapts to different ear sizes E, and allows for adjustment of the tightness of the open-back headphones 1 by adjusting the size of the ear-receiving space 120 and the ear inlet 1201. Thus, the sound-conducting tube 20 not only conducts sound but also cooperates with the main body 10 to clamp the ear E between the main body 10 and the sound-conducting tube 20.

[0068] The specific implementation in which the sound guide tube 20 is movably connected to the main body 10 is not limited to this application. In one embodiment of this application, the sound guide tube 20 is movably connected to the main body 10 by means of rotatability. During rotation relative to the main body 10, at least a portion of the sound guide tube 20 moves relative to the main body 10 in a thickness direction set by the main body 10, such that the dimensions of the ear cavity 120 and the ear inlet 1201 are adapted to change with the relative rotation between the sound guide tube 20 and the main body 10.

[0069] In one example of this application, the main body 10 has a connecting slot 110 into which the sound guide tube 20 is rotatably inserted. The connecting slot 110 may protrude outward from the outer surface of the main body 10, or inward from the inner surface of the main body 10, or be flush with both the outer and inner surfaces of the main body 10. It should be understood that the sound guide tube 20 may also be rotatably connected to the main body 10 in other ways.

[0070] The sound guide tube 20 of the open-back earphone 1 utilizes the concave and convex structures of the user's external auditory canal (e.g., the concha E2 and antitragus E3) and the shape of the sound guide tube 20 to stably place the open-back earphone 1 into the user's ear E. Compared to methods that primarily rely on tightly clamping the user's ear E from front to back, this application, while ensuring a more stable fit, can reduce the clamping force on the user's ear E, thereby improving wearing comfort, reducing the contact area with the user's external auditory canal skin, and decreasing the risk of ear canal infection. The open-back earphone 1 does not require any other internal components, allowing for a more flexible design of the sound guide tube 20.

[0071] In one example of this application, such as Figure 3 and Figure 4As shown, the sound guide tube 20 includes a first segment 21, a second segment 22, a third segment 23, a fourth segment 24, a fifth segment 25, and a sixth segment 26. One end of the first segment 21 is connected to the main body 10, and at least a portion of the first segment 21 extends toward the first side 104 of the main body 10 in the first direction D1; the second segment 22 extends from the first segment 21 in a bent manner relative to the first segment 21, and at least a portion of the second segment 22 extends upward relative to the first segment 21 in the second direction D2; the third segment 23 extends from the second segment 22 in a bent manner relative to the second segment 22; at least a portion of the third segment 23 extends in the first direction D1 toward a direction closer to the main body 10; the fourth segment 24 extends from the third segment 23 relative to the first segment 25. The third segment 23 extends in a bent manner, and at least a portion of the fourth segment 24 extends rearward relative to the third segment 23 in the thickness direction set by the main body 10; the fifth segment 25 extends from the fourth segment 24 relative to the third segment 23 in a bent manner, and at least a portion of the fourth segment 24 extends towards the first side 104 of the main body 10 in the first direction D1 relative to the fourth segment 24; the sixth segment 26 extends from the fifth segment 25 in a bent manner, and at least a portion of the sixth segment 26 extends rearward relative to the fifth segment 25 in the thickness direction set by the main body 10. The end of the sixth segment 26 forms the end of the sound guide tube 20, that is, the second end 202 of the sound guide tube 20. A first bend 210 is formed at the junction of the first segment 21 and the second segment 22. A second bend 220 is formed at the junction of the second segment 22 and the third segment 23. A third bend 230 is formed at the junction of the third segment 23 and the fourth segment 24. A fourth bend 240 is formed at the junction of the fourth segment 24 and the fifth segment 25. A fifth bend 250 is formed at the junction of the fifth segment 25 and the sixth segment 26.

[0072] The first segment 21 and the second segment 22 form a U-shaped groove with the main body 10. When the open-back earphone 1 is worn on the user's ear E, the user's earlobe E1 is accommodated in the U-shaped groove formed by the first segment 21 and the second segment 22 and the main body 10; the two bent portions 220 are located between the user's antitragus E3 and tragus; so that under the action of gravity, the second bent portion 220 abuts against the user's antitragus E3, thereby preventing the open-back earphone 1 from falling off to a certain extent by means of the relative positional relationship between the user's tragus, antitragus E3 and the second bent portion 220; at least a portion of the third segment 23, the fourth segment 24 and the fifth segment 25 are located in the user's concha E2; so that the open-back earphone 1 is prevented from falling off to a certain extent by means of the groove structure of the user's concha E2; the sixth segment 26 is located between the user's external auditory canal opening and the concha E2, so that the open-back earphone 1 is prevented from falling off to a certain extent by means of the bend between the user's concha E2 and the external auditory canal opening, thereby improving the wearing stability of the open-back earphone 1. In this way, even if the main body 10 and the sound tube 20 do not clamp the user's ear E, the open-back headphones 1 can be worn relatively stably on the user's ear E.

[0073] The first bend (i.e., the fifth bend 250) at the rear of the spherical structure 2020 of the sound guide tube 20 is supported in the ear clip cavity, with an inverted design to meet the function of supporting wearing.

[0074] like Figure 5 and Figure 6 As shown in another example of this application, the sound guide tube 20 includes a first segment 21, a second segment 22, and a third segment 23. One end of the first segment 21 is connected to the main body 10, and at least a portion of the first segment 21 extends toward the first side 104 of the main body 10 in the first direction D1; the second segment 22 extends from the first segment 21 in a bent manner relative to the first segment 21, and at least a portion of the second segment 22 extends upward relative to the first segment 21 in the second direction D2; the third segment 23 extends from the second segment 22 in a bent manner relative to the second segment 22; at least a portion of the third segment 23 extends in the first direction D1 in a direction away from the main body 10. The end of the third segment 23 forms the end of the sound guide tube 20, that is, the second end 202 of the sound guide tube 20. A first bend 210 is formed at the junction of the first segment 21 and the second segment 22. A second bend 220 is formed at the junction of the second segment 22 and the third segment 23.

[0075] When the open-back earphone 1 is worn on the user's ear E, the user's earlobe E1 is accommodated in the U-shaped groove formed by the first segment 21 and the second segment 22 and the main body 10; the two bent portions are located between the user's antitragus E3 and tragus; such that under the action of gravity, the second bent portion 220 or the third segment 23 abuts against the user's antitragus E3, thereby preventing the open-back earphone 1 from falling off to a certain extent by means of the relative positional relationship between the user's tragus, antitragus E3 and the second bent portion 220; at least a portion of the third segment 23 is located between the user's external auditory canal opening and concha E2, such that the open-back earphone 1 is prevented from falling off to a certain extent by means of the bend between the user's concha E2 and the external auditory canal opening, thereby improving the wearing stability of the open-back earphone 1.

[0076] It should be understood that the specific shape or extension of the sound guide tube 20 can also be implemented in other forms, mainly by improving the wearing stability of the open-back headphones 1 to a certain extent through the structure of the sound guide tube 20 and the user's ear E.

[0077] The color and light transmittance configuration of the sound guide tube 20 are not limited to this application. In one example of this application, at least a portion of the material of the sound guide tube 20 is transparent, which can increase the concealment of the open-back headphones 1 to a certain extent.

[0078] It is worth mentioning that, in one embodiment of this application, the open-back earphone 1 is provided with at least a shape-fixing structure within the sound guide tube 20 to ensure the shape and deformation of the sound guide tube 20. In one example of this application, the shape-fixing structure is implemented as a shape-fixable steel wire 40. The material of the guide tube 20 can be designed as: at least partially deformable material, such as deformable silicone, elastic rubber, elastic foam, etc.; or it can be designed as a rigid material that is difficult to deform.

[0079] Based on the above description of the open-back headphone 1, this application also proposes a method for wearing the open-back headphone 1, which includes the following steps: S110, inserting the sound tube 20 of the open-back headphone 1 into the user's external ear canal; S120, wearing the main body 10 of the open-back headphone 1 on the user's ear E.

[0080] In one embodiment of this application, during the process of wearing the main body 10 of the open-back earphone 1 on the user's ear E, the main body 10 of the open-back earphone 1 is worn on the back of the user's ear E.

[0081] In one embodiment of this application, during the process of wearing the main body 10 of the open-back earphone 1 on the user's ear E, the ear space 120 and / or the ear inlet 1201 between the sound guide tube 20 and the main body 10 are first adjusted by moving the sound guide tube 20; then, at least a portion of the user's ear E is inserted into the ear space 120 from the ear inlet 1201; next, after determining the position of the open-back earphone 1 relative to the user's ear E, the ear space 120 and / or the ear inlet 1201 between the sound guide tube 20 and the main body 10 are adjusted again by moving the sound guide tube 20, so as to stably wear the open-back earphone 1 on the user's ear E.

[0082] In one embodiment of this application, during the process of wearing the main body 10 of the open-back earphone 1 on the user's ear E, the user's earlobe E1 is accommodated in the U-shaped groove formed by the first segment 21 and the second segment 22 and the main body 10; the two bent portions are placed between the user's antitragus E3 and tragus; at least a portion of the third segment 23, the fourth segment 24 and the fifth segment 25 are nestled in the user's concha E2; the sixth segment 26 is placed between the user's external auditory canal opening and the concha E2, and the end of the sixth segment 26 extends into the external auditory canal opening or the external auditory canal.

[0083] In another embodiment of this application, during the process of wearing the main body 10 of the open-back earphone 1 on the user's ear E, the user's earlobe E1 is accommodated in the U-shaped groove formed by the first segment 21 and the second segment 22 and the main body 10; the two bent portions are placed between the user's antitragus E3 and tragus; and the end of the third segment 23 extends to the opening of the external auditory canal or into the external auditory canal.
