Description

Technical Field

[0001] This application relates to the field of acoustic technology, and more particularly to a pair of headphones. Background Technology

[0002] With the increasing popularity of electronic terminal technology and products, headphones have become a standard product in people's daily lives. They can be used with electronic devices such as mobile phones and computers. The use of headphones is gradually entering more and more daily life and work scenarios, providing users with convenient listening while also bringing various auditory experiences. Based on the common wearing methods of headphones on the market today, headphones are mainly divided into the following two types: In-ear headphones are the most common type of headphones. However, this type of headphone is supported by being inserted into the ear canal. The disadvantage of this is that wearing them for a long time may cause ear fatigue or discomfort, which may be uncomfortable for some users. Moreover, the sound production principle of this type of headphone directly enters the ear canal, and long-term wear may pose a potential risk of hearing damage.

[0003] Open-back headphones have also become increasingly popular in recent years. These headphones are usually fixed to the ears via hooks or suspension structures to avoid direct insertion into the ear canal.

[0004] However, regardless of whether it is an in-ear headphone or an open-back headphone, the headphone shell will come into contact with or compress the user's concha. Since the headphone shell is usually made of hard material, users will feel swelling in their concha when wearing headphones for a long time, which will affect the user's experience.

[0030] As an optional implementation, the sound transmission conduit extends along the thickness direction of the headphone body.

[0031] As an optional implementation, the wearing structure includes the following design parameters: Along the first horizontal direction, the distance 'a' between the longitudinal centerline and the endpoint of the first support portion; Along the first vertical direction, the distance b between the transverse centerline and the lower end point of the first support portion; Along the first vertical direction, the distance c between the transverse centerline and the upper end point of the second support portion; Along the first horizontal direction, the distance d between the longitudinal centerline and the endpoint of the second support portion; Wherein, taking the wearing structure in the wearing state as a reference, the first vertical direction is the height direction of the auricle, and the first horizontal direction is the direction that is perpendicular to the first vertical direction and coplanar with the side of the wearing structure facing the auricle; The longitudinal centerline is set to pass through the center of the sound transmission hole and be parallel to the first vertical direction; the transverse centerline is set to pass through the center of the sound transmission hole and be parallel to the first horizontal direction.

[0033] As an optional implementation, based on the cross-section of the first support portion on the horizontal plane, the cross-section includes an upper end face and a lower end face respectively disposed in the second vertical direction, the lower end face is planar, and the upper end face is an arc surface concave towards the lower end face; Along the second horizontal direction, the two ends of the lower end face bend and extend toward the two ends of the upper end face to connect with the upper end face and form a protrusion; Wherein, taking the wearing structure in the wearing state as a reference, the first vertical direction is the height direction of the auricle, the first horizontal direction is the direction perpendicular to the first vertical direction and coplanar with the side of the wearing structure facing the auricle, the horizontal plane is set as the intersection of the first horizontal direction and the vertical direction, the vertical direction is set as the direction perpendicular to the intersection of the first horizontal direction and the first vertical direction, and the second horizontal direction is set as the width direction of the cross section on the horizontal plane.

[0034] As an optional implementation, the wearing structure also includes the following design parameters: Along the second vertical direction, the distance e between the protrusion and the lower end face; Along the second vertical direction, the distance e1 between the lowest point of the upper end face and the lower end face; Along the second horizontal direction, the distance e2 between the two endpoints of the cross section; Wherein, the second vertical direction is defined as the height direction of the cross section on the horizontal plane; Wherein, at least one of e, e1, and e2 satisfies the following corresponding range: The range of e is 1mm to 5mm; the range of e1 is 0.5*e to 0.8*e; the range of e2 is 1mm to 7mm.

The charging structure is located in the housing and is at least partially exposed outside the housing. The transducer, the energy storage device, and the charging structure are all electrically connected to the circuit board.

[0037] Compared with the prior art, the headphones provided in this application have the following main advantages: The headphones include the headphone body, the wearing structure, and the sound transmission structure. When the headphones are in the wearing state (i.e., the user is wearing the headphones), at least part of the wearing structure can be locked into the concha of the user's auricle, while the headphone body is located outside the concha. In other words, the headphones are mainly worn by locking into the concha through the wearing structure, which effectively improves the stability of the headphones and makes them less likely to loosen or fall off during exercise or activities.

[0038] The sound emitted by the transducer of the earphone body is conducted to the vicinity of the user's ear canal through the sound transmission structure connected between the wearing structure and the earphone body. When the wearing structure is in the aforementioned state, both the wearing structure and the sound transmission structure are located outside the ear canal. Compared with in-ear headphones in related technologies, the wearing structure of this application does not directly insert into the user's external ear canal from the ear canal opening, which can effectively protect the user's hearing from damage, and is not easy to cause discomfort when worn for a long time. It also allows the user to hear the external environmental sounds while listening to the sound emitted by the earphone.

[0039] Furthermore, the earphone body is located outside the user's concha. On one hand, this prevents the earphone body from contacting the skin on the concha, reducing pressure on the user's concha and minimizing swelling when wearing the earphone. This improves comfort during extended wear. Also, it prevents the earphone body from blocking the ear canal and concha, allowing for an open-back design that enables users to hear ambient sounds while listening to the earphones. On the other hand, it allows for greater flexibility in the design of the earphone body, as the shape and size are not limited by the concha. Attached Figure Description

[0042] 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. The terms used in this specification are for the purpose of describing particular embodiments only and are not intended to limit the present application. For example, terms such as “length,” “width,” “upper,” “lower,” “left,” “right,” “front,” “rear,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer” indicate orientations or positions based on the orientations or positions shown in the accompanying drawings and are for ease of description only, and should not be construed as limiting the present technical solution.

[0043] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion; the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a particular order. "A plurality of" means two or more, unless otherwise explicitly specified.

[0044] In the description and claims of this application and the foregoing drawings, when an element is referred to as "fixed to," "mounted to," "set on," or "connected to" another element, it may be directly or indirectly located on that other element. For example, when an element is referred to as "connected to" another element, it may be directly or indirectly connected to that other element.

[0045] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] Figure 1 This is a schematic diagram of an exemplary auricle according to some embodiments of this specification. Figure 1As shown, the auricle 100 may include an ear canal opening 101, a concha cavity 102, a cymba conchae 103, a triangular fossa 104, an antihelix 105, a scaphoid fossa 106, an helix 107, an earlobe 108, and a crus of the helix 109. It should be noted that, for ease of description, in this embodiment, the upper crus 1011 and lower crus 1012 of the antihelix, as well as the antihelix 105, are collectively referred to as the antihelix region. In some embodiments, the stability of headphone wearing can be achieved by using one or more parts of the auricle 100 to support the headphones. In some embodiments, the ear canal opening 101, the concha cavity 102, the cymba conchae 103, the triangular fossa 104, etc., have a certain depth and volume in three-dimensional space, which can be used to meet the wearing requirements of headphones. For example, headphones (e.g., in-ear headphones) can be worn in the ear canal opening 101. In some embodiments, headphones can be worn using other parts of the auricle 100 besides the ear canal opening 101. For example, the headphones can be worn using parts such as the cymba conchae 103, triangular fossa 104, antihelix 105, scaphoid 106, or helix 107, or combinations thereof. In some embodiments, to improve the comfort and reliability of the headphones, parts such as the user's earlobe 108 can also be used. By using parts of the auricle 100 other than the ear canal opening 101 to achieve headphone wearing and sound propagation, the user's ear canal opening 101 can be "liberated". When the user wears headphones (open-back headphones), the headphones do not block the user's ear canal opening 101, and the user can receive both sound from the headphones and sound from the environment (e.g., horns, car bells, surrounding voices, traffic signals, etc.), thereby reducing the probability of traffic accidents. In some embodiments, the headphones can be designed to fit the auricle 100 according to its structure, so that the sound-producing part of the headphones can be worn at different positions on the auricle. For example, when the headphones are open-back headphones, they may include a suspension structure (e.g., a wearing structure) and a sound-producing part, which is physically connected to the suspension structure. The suspension structure may be adapted to the shape of the auricle to place the entire or part of the auricle's sound-producing part on the front side of the helix 109 (e.g., Figure 1 The area J enclosed by the dotted line. For example, when a user wears open-back headphones, the entire or partial structure of the sound-producing part can contact the upper part of the ear canal opening 101 (e.g., the location of one or more parts such as the helix crus 109, cymba conchae 103, triangular fossa 104, antihelix 105, scaphoid 106, and helix 107). For yet another example, when a user wears open-back headphones, the entire or partial structure of the sound-producing part can be located within the cavity formed by one or more parts of the auricle (e.g., the conchae cavity 102, cymba conchae 103, triangular fossa 104, etc.). Figure 1The region M1, enclosed by the dotted line, includes at least the cymba conchae 103 and the triangular fossa 104, and the region M2, which includes at least the cavum conchae 102. Individual differences may exist among users, resulting in variations in the shape, size, and other dimensions of the auricle. For ease of description and understanding, unless otherwise specified, this specification will primarily use an auricle model with a "standard" shape and size as a reference to further describe how the headphones in different embodiments are worn on this auricle model.

[0047] The description of the auricle 100 above is for illustrative purposes only and is not intended to limit the scope of this application. Those skilled in the art can make various changes and modifications based on the description in this application. For example, a portion of the headphone structure may cover part or all of the ear canal opening 101. These changes and modifications are still within the protection scope of this application.

[0048] It should also be noted that the headphones may include, but are not limited to, air conduction headphones and bone conduction headphones. Specifically, in some embodiments, the headphones may be combined with products such as glasses, headphones, head-mounted displays, and AR / VR headsets.

[0049] Combination Figure 6 and Figure 8 For ease of description in the following embodiments, it should be noted that the width direction of the earphone 200 in the wearing state is defined as: the direction in which the earphone 200 is in the same direction as the width direction of the auricle 100 when the earphone 200 is in the wearing state; the length direction of the earphone 200 in the wearing state is defined as: the direction in which the earphone 200 is in the same direction as the height direction of the auricle 100 when the earphone 200 is in the wearing state; and the thickness direction of the earphone 200 in the wearing state is defined as: the direction perpendicular to the auricle 100 when the earphone 200 is in the wearing state. Based on this, a YZ coordinate system and an XY coordinate system are established, with the width direction of the earphone 200 in the wearing state as the X-axis direction, the length direction of the earphone 200 in the wearing state as the Y-axis direction, and the thickness direction of the earphone 200 in the wearing state as the Z-axis direction.

[0050] Figure 2 This is a schematic diagram of the wearing state of the earphone 200 in one embodiment of this application. Based on this, for the convenience of the description of the embodiments below, an X'Y' coordinate system is established, with the height direction of the auricle 100 as the Y' axis direction.

[0051] Figure 14 This is a three-dimensional structural diagram of the wearing structure 20 provided in one embodiment of this application. Based on this, for the convenience of the description of the embodiments below, an X1Y1Z1 coordinate system is established, defining the width direction of at least a portion of the wearing structure 20 as the X1 axis direction, the length direction of the aforementioned portion of the wearing structure 20 as the Y1 axis direction, and the thickness direction of the aforementioned portion of the wearing structure 20 as the Z1 axis direction.

[0052] Figure 15 This is a planar schematic diagram of the earphone 200 with the wearing structure 20 of this application in a wearing state, based on the side of the first support portion 21 facing the ear canal opening 101. Based on this, for the convenience of the following description of the corresponding embodiments, an X2Y2 plane coordinate system is established on the aforementioned plane, with the first horizontal direction being the X2 axis direction and the first vertical direction being the Y2 axis direction.

[0053] Figure 16 for Figure 7 The cross-sectional view at BB is specifically the cross-section of the first support portion 21. Based on this, for the convenience of the description of the corresponding embodiment below, an X3Y3 plane coordinate system is established on the aforementioned cross-section, with the horizontal plane being the X3Y3 plane (the cross-section is located on the horizontal plane), the second horizontal direction being the X3 axis direction, and the second vertical direction being the Y3 axis direction.

[0054] It is understandable that the coordinate system settings mentioned above can be flexibly configured according to actual needs, and no specific limitations are made here.

[0055] This application provides an embodiment of an earphone 200, such as... Figures 1 to 4 As shown in the figure, the earphone 200 may include an earphone body 10, a wearing structure 20, and a sound transmission structure 30. A transducer 11 may be disposed inside the earphone body 10. The transducer 11 converts electrical signals into sound waves, enabling the user to hear sound. The wearing structure 20 may be connected to the earphone body 10. The sound transmission structure 30 may be disposed between the wearing structure 20 and the earphone body 10, so that the wearing structure 20 is connected to the earphone body 10. The sound transmission structure 30 can be used to conduct the sound emitted by the transducer 11 to the vicinity of the ear canal opening 101.

[0056] Specifically, the transducer 11 can convert electrical energy into mechanical energy through different physical principles, thereby driving the diaphragm to vibrate and generate sound. Optionally, the transducer 11 can be a moving-coil transducer, a capacitive transducer, or a piezoelectric transducer, etc.

[0057] When the earphone 200 is in the wearing state (i.e., the user is wearing the earphone 200), the wearing structure 20 can be located outside the ear canal opening 101, and at least part of the wearing structure 20 can be locked inside the concha cavity 102 of the auricle, so that the earphone body 10 is located outside the concha cavity 102. It can be understood that the earphone 200 is mainly worn by the wearing structure 20 being locked inside the concha cavity 102. Compared with the method of wearing by hanging on the auricle 100, the wearing method of being locked inside the concha cavity 102 can effectively improve the stability of the earphone 200, and it is not easy for it to shift, loosen or fall off during sports or activities.

[0058] Furthermore, the sound emitted by the transducer 11 inside the earphone body 10 is transmitted through the sound transmission structure 30 and then through the wearing structure 20 to the vicinity of the ear canal opening 101. When the wearing structure 20 is in the aforementioned state, both the wearing structure 20 and the sound transmission structure 30 are located outside the ear canal opening 101. Compared to in-ear headphones in related technologies, the wearing structure 20 of this application does not directly insert into the user's external ear canal through the ear canal opening 101, which can effectively protect the user's hearing from damage, and is less likely to cause discomfort even after long-term wear. Since the wearing structure 20 is located outside the ear canal opening 101, the ear canal opening 101 is in an open state, meaning that the user is in a relatively open sound environment when wearing the earphone 200. This allows the user to hear the sound emitted by the transducer 11 while also hearing the external sound environment, enabling them to be aware of sudden situations around them and effectively eliminate safety hazards.

[0059] Furthermore, the earphone body 10 is entirely located outside the concha 102. On one hand, this prevents the earphone body 10 from contacting the skin on the concha 102, reducing pressure on the user's concha 102 from the components of the earphone 200. This helps reduce swelling in the concha 102 when the user wears the earphone 200, thus improving comfort during extended wear. Additionally, the earphone body 10 does not obstruct the user's ear canal opening 101 or concha 102, facilitating the open-back design of the earphone 200. This allows the user to hear ambient sounds while listening to the sound emitted by the earphone 200. On the other hand, the shape and size of the earphone body 10 are not limited by the concha 102, allowing for more flexible design. In short, with the entire earphone 200 located outside the ear canal opening 101, it effectively protects the user's hearing from loss and is less likely to cause discomfort even during prolonged wear.

[0060] In summary, compared with existing technologies, this headset 200 has at least the following beneficial effects: When the earphone 200 is in the wearing state (i.e., the user is wearing the earphone 200), at least part of the wearing structure 20 can be locked into the concha cavity 102 of the user's auricle, while the earphone body 10 is located outside the concha cavity 102. That is, the earphone 200 is mainly worn by locking the wearing structure 20 into the concha cavity 102, which effectively improves the stability of the earphone 200 and makes it less likely to loosen or fall off during sports or activities.

[0061] The sound emitted by the transducer 11 of the earphone body 10 is conducted to the vicinity of the user's ear canal opening 101 through the sound transmission structure 30 connected between the wearing structure 20 and the earphone body 10. When the wearing structure 20 is in the aforementioned state, both the wearing structure 20 and the sound transmission structure 30 are located outside the ear canal opening 101. Compared with in-ear headphones in related technologies, the wearing structure 20 of this application does not directly insert into the user's external ear canal from the ear canal opening 101, which can effectively protect the user's hearing from damage, and is less likely to cause discomfort even after long-term wear. Since the wearing structure 20 is located outside the ear canal opening 101, the ear canal opening 101 is in an open state, that is, when the user wears the earphone 200, they are in a relatively open sound environment. They can hear the sound emitted by the transducer 11 while also hearing the external sound environment, and can pay attention to sudden situations around them, effectively eliminating safety hazards.

[0062] Furthermore, the earphone body 10 is entirely located outside the concha 102. On one hand, this prevents the earphone body 10 from contacting the skin on the concha 102, reducing pressure on the user's concha 102 from the components of the earphone 200. This helps reduce swelling in the concha 102 when the user wears the earphone 200, thus improving comfort during extended wear. Additionally, the earphone body 10 does not obstruct the user's ear canal opening 101 or concha 102, facilitating the open-back design of the earphone 200. This allows the user to hear ambient sounds while listening to the sound emitted by the earphone 200. On the other hand, the shape and size of the earphone body 10 are not limited by the concha 102, allowing for more flexible design. In short, with the entire earphone 200 located outside the ear canal opening 101, it effectively protects the user's hearing from loss and is less likely to cause discomfort even during prolonged wear.

[0063] To enable those skilled in the art to better understand the present application, the following will be discussed in conjunction with the appendix. Figures 1 to 18 The technical solutions in the embodiments of this application will be clearly and completely described.

[0064] In some embodiments, such as Figure 2 As shown, when the earphone 200 is in the wearing state, at least a portion of the earphone body 10 can contact the auricle 100 and generate friction, thus providing auxiliary support for the earphone body 10. Specifically, at least a portion of the earphone body 10 can contact the earlobe 108. Since the earlobe 108 is located below the concha 102, the earphone body 10 can rest against the earlobe 108 of the auricle 100. The earphone body 10 is subjected to a downward gravitational force, and after contacting the earlobe 108, a frictional force is generated in the opposite direction of gravity, so that the earlobe 108 provides a certain degree of auxiliary support for the earphone body 10. Combined with the main support function of the wearing structure 20 for the earphone body 10, the stability of the earphone 200 during wearing is further enhanced.

[0065] In other embodiments, the earphone body 10 may also abut against the helix foot 109, helix 107, etc. of the auricle 100.

[0066] In some embodiments, such as Figure 2 As shown, when the earphone 200 is in the wearing state, in the height direction (Y' axis direction) of the auricle 100, the height h of the upper end of the earphone body 10 can be lower than the height H of the upper end of the ear canal opening 101, so that the center of gravity of the earphone body 10 is oriented towards the earlobe 108, ensuring that the earphone body 10 can contact the earlobe 108 and generate a frictional force that can assist in supporting the earphone 200. Optionally, the difference between H and h can be in the range of 1mm ≤ Hh ≤ 3mm. Within this range, the center of gravity of the wearing structure 20 can be located in an appropriate position so that the wearing structure 20 can be stably worn in the auricle 100, while the auricle 100 can contact the earphone body 10, so that the auricle 100 provides auxiliary support for the earphone body 10. In some specific embodiments, the value of Hh can be 1mm or 2.3mm, etc.

[0067] In some embodiments, such as Figure 6 As shown, when the earphone 200 is in the wearing state, the side of the earphone body 10 that contacts the auricle 100 can be set as the first contact surface P1, and the side of the wearing structure 20 facing the auricle 100 can be set as the second contact surface P2. The included angle between the first contact surface P1 and the second contact surface P2 can be an acute angle, so that when the wearing structure 20 is pressed against the concha cavity 102, the earphone body 10 can just hang down at the earlobe 108 and make the earphone body 10 contact the earlobe 108 to generate a frictional force that can help support the earphone body 10.

[0068] In some embodiments, such as Figure 6 and Figure 7As shown, the intersection line of the first contact surface P1 and the first cross-section (YZ plane) can be set as the first intersection line L1, and the intersection line of the second contact surface P2 and the first cross-section can be set as the second intersection line L2. The angle between the first intersection line L1 and the second intersection line L2 is α, and the range of α can be: 0°≤α≤30°. The first cross-section can be parallel to the intersection plane of the length direction (Y-axis direction) and the thickness direction (Z-axis direction) of the earphone 200 in the wearing state. Understandably, when the value of α is within the aforementioned range, the wearing structure 20, combined with its deformable characteristics, can be completely locked into the concha cavity 102, while the earphone body 10 just hangs down at the earlobe 108, thus simultaneously taking into account the stability, fit, and comfort of wearing the earphone 200. If the value of α is >30°, it may result in the earphone body 10 not contacting the earlobe 100 when the wearing structure 20 is locked into the auricle 100, and the auricle 100 cannot provide auxiliary support for the earphone body 10. Preferably, the range of α can be 18°≤α≤22°. The optimal value of α within this range further enhances the stability, fit, and comfort of the headphones 200. In some specific embodiments, the value of α can be 19°, 20°, or 27.5°, etc.

[0069] In some embodiments, such as Figure 8 and Figure 9 As shown, the intersection of the first contact surface P1 and the second cross-section (XY plane) can be set as the third intersection line L3, and the intersection of the second contact surface P2 and the second cross-section (XY plane) can be set as the fourth intersection line L4. The angle between the third intersection line L3 and the fourth intersection line L4 can be β, and the range of β can be: 0°≤β≤20°. The second cross-section can be parallel to the intersection of the length direction (Y-axis direction) and the width direction (X-axis direction) of the earphone 200 when worn. Understandably, when the value of β is within the aforementioned range, the earphone body 10, which hangs on the earlobe 108 when the user wears the earphone 200, can make better contact with the earlobe 108, ensuring friction between the earphone body 10 and the earlobe 108, effectively improving the stability of wearing the earphone 200. If the value of β is >20°, it may result in the earphone body 10 not contacting the earlobe 100 when the wearing structure 20 is pressed against the auricle 100, and the auricle 100 cannot provide auxiliary support for the earphone body 10. Preferably, the range of β can be 5°≤β≤10°. A value of β within this preferred range can better increase the friction between the earphone body 10 and the earlobe 108, further improving the stability of the earphone 200 during wear. In some specific embodiments, the value of β can be 7°, 9°, or 16°, etc.

[0070] Optionally, in order to make the angle between the first contact surface P1 and the second contact surface P2 acute, the wearing structure 20 can be installed at an angle relative to the earphone body 10, or the wearing structure 20 can be installed parallel to the earphone body 10. However, the wearing structure 20 itself has an inclined surface that is inclined relative to the overall structure of the wearing structure 20, and at least a portion of the inclined surface is formed as the second contact surface P2.

[0071] In some embodiments, such as Figure 4 As shown, the sound transmission structure 30 may include a sound transmission hole 31 and a sound outlet hole (not shown in the figure) communicating with the sound transmission hole 31. The sound transmission hole 31 may be disposed and extend through the wearing structure 20, and the sound outlet hole may be disposed in the headphone body 10. Understandably, the sound emitted by the transducer 11 in the headphone body 10 can be transmitted out of the headphone body 10 from the sound outlet hole, and then conducted through the sound transmission hole 31 on the wearing structure 20 to the vicinity of the user's ear canal opening 101, and finally enter the ear canal so that the user can hear the audio played by the headphone 200.

[0072] In some embodiments, such as Figure 4 and Figure 12 As shown, the sound transmission structure 30 may further include a sound transmission conduit 32, with its two ends connected to the earphone body 10 and the wearing structure 20, respectively. The sound transmission hole 31 is connected to the earphone body 10 through the sound transmission conduit 32, so that the sound emitted by the transducer 11 can be transmitted to the vicinity of the ear canal opening 101. The sound emitted by the transducer 11 in the earphone body 10 is transmitted out of the earphone body 10 through the sound outlet, then reaches the sound transmission hole 31 of the wearing structure 20 through the sound transmission conduit 32, and finally enters the vicinity of the user's ear canal opening 101 from the sound transmission hole 31.

[0073] In this embodiment, the sound transmission structure 30 not only conducts sound but also connects the wearing structure 20 to the headphone body 10. That is, it enables the wearing structure 20 to be installed on the headphone body 10. The sound transmission structure 30 achieves structural reuse, which helps to simplify the structural design of the headphone 200.

[0074] In other embodiments, the earphone 200 may also be provided with other connection structures to enable the wearing structure 20 to be installed on the earphone body 10, and the sound transmission structure 30 only serves to conduct sound.

[0075] In some embodiments, such as Figure 12As shown, the two ends of the sound transmission duct 32 may respectively have a first connecting surface Q1 connected to the headphone body 10 and a second connecting surface Q2 connected to the wearing structure 20. The first connecting surface Q1 may be arranged parallel to the second connecting surface Q2, so that when the headphone 200 is in the wearing state, the headphone body 10 can tilt towards the earlobe 108 to contact the earlobe 108 and generate sufficient frictional force to assist in supporting the wearing of the headphone 200. Preferably, the first connecting surface Q1 may be tilted relative to the second connecting surface Q2, so that when the wearing structure 20 is installed on the headphone body 10, the wearing structure 20 can tilt relative to the headphone body 10, thereby increasing the tilting degree of the headphone body 10 towards the earlobe 108 when the headphone 200 is in the wearing state, and generating sufficient frictional force to assist in supporting the wearing of the headphone 200, further increasing the frictional force between the headphone body 10 and the earlobe 108.

[0076] In some embodiments, the sound transmission duct 32 and the earphone body 10 can be integrally formed; or, the sound transmission duct 32 and the wearing structure 20 can be integrally formed. The structure is simple, stable, and easy to manufacture.

[0077] In some embodiments, such as Figure 12 As shown, the sound transmission duct 32 can extend along the thickness direction of the earphone body 10, specifically protruding towards the side of the wearing structure 20 and located at the end of the earphone body 10 away from the earlobe 108, so that a larger portion of the earphone body 10 can contact the earlobe 108. Alternatively, the sound transmission duct 32 can protrude from the side of the wearing structure 20 towards the earphone body 10. Optionally, when the sound transmission duct 32 is provided on the earphone body 10, it can be arranged parallel to the thickness direction of the earphone body 10 or inclined. The same applies when the sound transmission duct 32 is provided on the wearing structure 20, and will not be described further here.

[0078] In some embodiments, such as Figure 13 As shown, a latch 33 may be provided on the outer edge of the free end of the sound transmission duct 32, and a slot 23 may be provided in the sound transmission hole 31 or the sound outlet hole to engage with the latch 33. When the latch 33 and the slot 23 are engaged, they can restrict the relative rotation of the wearing structure 20 and the headphone body 10, thus playing a limiting role. Furthermore, the cross-section of the channel structure inside the sound transmission duct 32 may be elliptical, circular, or other shapes.

[0079] In some embodiments, such as Figure 2 and Figure 4As shown, the wearing structure 20 can be made of silicone, low-pressure foam, or high-elasticity polyester, giving it a certain degree of deformation capability. The wearing structure 20 includes a first support portion 21 and a second support portion 22 that are interconnected. When the earphone 200 is in the wearing state, the first support portion 21 can be engaged within the concha 102, and the second support portion 22 can be engaged within the cymba concha 103 of the auricle 100, which is connected to the concha 102. Understandably, both the first support portion 21 and the second support portion 22 can have a certain degree of deformation capability, so that when the wearing structure 20 is placed within the concha 102, the first support portion 21 can adaptively deform according to the different shapes of the user's concha 102, and the second support portion 22 can also adaptively deform according to the different shapes of the user's cymba concha 103, with both working together to stably fix it within the concha 102. Furthermore, the first support portion 21 and the second support portion 22 are independent of each other. When the first support portion 21 is squeezed by the concha cavity 102, it will not affect the second support portion 22. Conversely, when the second support portion 22 is squeezed by the concha sac 103, it will not affect the first support portion 21. Therefore, the stability of the wearing structure 20 in the concha cavity 102 can be ensured, and the earphone body 10 and the earlobe 108 can always be kept in contact and are not easy to be displaced.

[0080] Understandably, such as Figure 3 As shown, when the first support 21 is in a free state (i.e., not compressed), point m represents the initial shape of the first support 21, at which point no deformation occurs. However, when it is in a wearing state (i.e., compressed), the portion of the first support 21 compressed by the concha 102 deforms according to the shape of that location in the concha 102, as shown at point m', and generates a force opposite to the direction of the applied force, which can hold it in place within the concha 102. When the second support 22 is in a free state (i.e., not compressed), point n represents the initial shape of the second support 22, at which point no deformation occurs. However, when it is in a wearing state (i.e., compressed), the portion of the second support 22 compressed by the cymba concha 103 deforms according to the shape of that location in the cymba concha 103, as shown at point n', and generates a force opposite to the direction of the applied force, which can hold it in place within the cymba concha 103.

[0081] In some embodiments, such as Figure 2 and Figure 4As shown, in the thickness direction (Z-axis direction) of the earphone body 10, the first support portion 21 can be closer to the earphone body 10 relative to the second support portion 22. It is understood that to ensure the earphone body 10 always hangs down at the earlobe 108 and remains in contact with the earlobe 108, and since the concha 102 is closer to the earlobe 108 than the cymba concha 103, placing the first support portion 21 closer to the earphone body 10 relative to the second support portion 22 allows the end of the earphone body 10 away from the wearing structure 20 to gradually tilt towards the auricle 10, so that it can contact the auricle 100. This allows the auricle 100 to provide auxiliary support for the earphone body 10, which is more conducive to the stability of the wearing structure.

[0082] In some embodiments, such as Figure 12 and Figure 14 As shown, the first side 24 of the wearing structure 20 is also provided with a clearance portion 211, which is connected to the sound transmission hole 31. When the wearing structure 20 is in the wearing state, the clearance portion 211 can be used to allow at least a portion of the first side 24 of the wearing structure 20 to have a gap with the ear canal opening 101.

[0083] The first side 24 is the side of the wearing structure 20 facing the ear canal opening 101. A clearance portion 211 is provided on the first side 24 so that when the wearing structure 20 is in the wearing state, the clearance portion 211 allows the sound emitted by the transducer 11 of the earphone 200 and external ambient sounds to pass through the clearance portion 211 before entering the ear canal through the ear canal opening 101. This means that the user can clearly hear the sound from the earphone 200 while also hearing the surrounding ambient sounds, ensuring a relatively open sound environment for the user when wearing the earphone 200 using this wearing structure 20, effectively eliminating safety hazards. At the same time, it also reduces the pressure of the first side 24 of the wearing structure 20 on the skin near the user's ear canal opening 101, which helps improve the user's comfort when wearing the wearing structure 20.

[0084] In some embodiments, such as Figure 14 As shown, the recessed portion 211 is formed from the side of the wearing structure 20 facing the auricle 100 in the thickness direction (Z1 axis direction) of the wearing structure 20 to the other side, so that when the wearing structure 20 is in the wearing state, at least a part of the wearing structure 20 has a recessed space between it and the vicinity of the ear canal opening 101 (mainly referring to the vicinity of the auricle 100), so that the sound emitted by the transducer 11 of the earphone 200 and the external ambient sound can first pass through the recessed space and then enter the ear canal through the ear canal opening 101. That is, the user can hear the sound of the earphone 200 clearly while also hearing the surrounding ambient sound, ensuring that the user is in a relatively open sound environment when wearing the earphone 200 with the wearing structure 20, effectively eliminating safety hazards.

[0085] Optionally, the shape of the clearance portion 211 can be circular, elliptical, square, or other irregular shapes, and can be selected according to the actual situation. In this embodiment, no specific limitation is made.

[0086] Optionally, the clearance portion 211 can be a complete groove structure or an incomplete groove structure. For example, it can be a groove structure with notches on the side wall or bottom surface, or it can be a groove structure connected with other holes or grooves. The specific choice can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0087] In other embodiments, the clearance portion 211 may also be a through hole, which is at least partially corresponding to the ear canal opening 101 at one end of the first side 24, and the other end of the through hole is connected to the external environment.

[0088] In some embodiments, when the wearing structure 20 is in the wearing state, the projection of the ear canal opening 101 on the first side 24 in the thickness direction (Z1 axis direction) of the wearing structure 20 may be located within the clearance portion 211.

[0089] This also avoids the first side 24 of the wearing structure 20 from squeezing the skin around the user's ear canal opening 101, which helps to further improve the user's comfort when wearing the wearing structure 20. In addition, the recess 211 forms a sound cavity covering the ear canal opening 101, which can better transmit the sound transmitted through the sound hole 31 to the user's ear canal opening 101, reduce the energy loss of sound, and reduce the risk of sound leakage.

[0090] In some embodiments, such as Figure 14 As shown, both the sound transmission hole 31 and the clearance portion 211 can be arranged along the thickness direction (Z1 axis direction) of the wearing structure 20. In the thickness direction of the wearing structure 20, the projection of the sound transmission hole 31 on the first side 24 is located in the clearance portion 211.

[0091] Understandably, the projection of the ear canal opening 101 on the first side 24 is located within the clearance portion 211, and the projection of the sound transmission hole 31 on the first side 24 is located within the clearance portion 211, so that the clearance portion 211 can communicate with the ear canal opening 101.

[0092] This design allows for a shorter propagation path of sound emitted by the earphone 200 through the sound transmission hole 31 and the recess 211 to the ear canal opening 101, which improves sound propagation efficiency and reduces sound energy loss. Furthermore, the cross-sectional area of ​​the sound transmission hole 31 perpendicular to its thickness is smaller than that of the recess 211, which helps to concentrate the sound transmitted through the sound transmission hole 31, thus improving the user's sound reception.

[0093] In some embodiments, such as Figure 4 As shown, the first support part 21 and / or the second support part 22 may have weight reduction holes 221, which can not only achieve the miniaturization and weight reduction of the overall structure, but also increase the deformation capacity of the first support part 21 and the second support part 22, and further optimize the comfort of the first support part 21 and the second support part 22 when they are locked in the ear armor boat 103.

[0094] Optionally, the weight reduction hole 221 may be provided only on the first support part 21, or the weight reduction hole 221 may be provided only on the second support part 22; of course, the weight reduction hole 221 may be provided on both the first support part and the second support part 22 at the same time.

[0095] In some embodiments, when the first support 21 is provided with a weight reduction hole 221, the weight reduction hole 221 is connected to the clearance part 211, so that the clearance part 211 is an incomplete groove structure. External ambient sound can be transmitted to the clearance part 211 through the weight reduction hole 221, which further helps the user to hear the external ambient sound while listening to the sound emitted by the headphones 200.

[0096] In some embodiments, such as Figure 14 As shown, the cross-section is defined as the intersection of the length direction (Y1 axis direction) and the width direction (X1 axis direction) of the first support portion 21. Based on this, the shape of the clearance portion 211 in the cross-section can be at least partially the same as the shape of the first support portion 21 in the cross-section, and the former's size can be proportionally slightly smaller than the latter's size, to ensure that there is a sufficiently large clearance space, so as to improve the effect that the user can hear the sound of the headphones 200 clearly while also hearing the surrounding ambient sound.

[0097] Optionally, the shape of the clearance portion 211 in cross-section being at least partially the same as the shape of the first support portion 21 in cross-section means that the shape of the clearance portion 211 in cross-section is partially the same as the shape of the first support portion 21 in cross-section, or the shape of the clearance portion 211 in cross-section is completely the same as the shape of the first support portion 21 in cross-section. The specific choice can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0098] In some embodiments, such as Figure 4 , Figure 10 and Figure 11 As shown, the external structure of the wearing structure 20 includes, but is not limited to, the following: The first type, such as Figure 4 and Figure 14As shown, the first support portion 21a is arc-shaped, and the second support portion 22a is hook-shaped. The tip of the second support portion 22a extends away from the first support portion 21a, and the other end transitions to the edge of the first support portion 21a. When the wearing structure 20 is in the wearing state, the arc-shaped portion of the first support portion 21a abuts against the concha cavity 102, and the tip of the second support portion 22a abuts against the cymba conchae 103. Optionally, the first support portion 21a may be provided with a notch 213 to increase the degree of deformation of the first support portion 21a.

[0099] Based on this structure, the clearance portion 211 is recessed from the side of the first support portion 21a facing the ear canal opening 101 in the thickness direction (Z1 axis direction) of the wearing structure 20b to the other side. The clearance portion 211 is located near the connection between the first support portion 21a and the second support portion 22a. Specifically, a groove structure is formed on that side of the first support portion 21b in the aforementioned manner. This groove structure creates a clearance space between at least a portion of the first support portion 21b and the vicinity of the ear canal opening 101. The clearance portion 211 communicates with the sound transmission hole 31. This ensures that the user can clearly hear the sound of the headphones 200 while also making it easier to hear ambient sounds, further improving safety. Furthermore, a weight-reducing hole 221 can be provided on the first support part 21a. The weight-reducing hole 221 is connected to the clearance part 211, making the clearance part 211 an incomplete groove structure. External ambient sound can be transmitted to the clearance part 211 through the weight-reducing hole 221, which further helps the user to hear the external ambient sound while listening to the sound emitted by the headphones 200.

[0100] The second type, such as Figure 10 As shown, both the first support portion 21b and the second support portion 22b are hook-shaped, with their tips extending in opposite directions. The length of the first support portion 21b is less than the length of the second support portion 22b. When the wearing structure 20 is in the wearing state, the arcuate portion of the hook of the first support portion 21b abuts against the concha 102 along its contour, with its tip abutting against the top of the concha 102. The tip of the second support portion 22b abuts against the cymba concha 103. Alternatively, the second support portion 22b can also be a wider, flatter sheet-like structure.

[0101] Based on this structure, the clearance portion 211 can be recessed from the side of the first support portion 21b facing the ear canal opening 101 in the thickness direction (Z1 axis direction) of the wearing structure 20b to the other side. Specifically, a groove structure is formed on that side of the first support portion 21b in the aforementioned manner. This groove structure creates a clearance space between at least a portion of the first support portion 21b and the vicinity of the ear canal opening 101. The clearance portion 211 is connected to the sound transmission hole 31.

[0102] The third type, such as Figure 11 As shown, the first support portion 21c and the second support portion 22c are connected at their ends to form an integral ring structure, and the length of the second support portion 22c is greater than the length of the first support portion 21c. Specifically, the ring structure can be an oval ring, with the end of the first support portion 21c away from the second support portion 22c being a large circle, and the end of the second support portion 22c away from the first support portion 21c being a small circle. When the wearing structure 20 is in the wearing state, the large circle of the first support portion 21c abuts against the concha cavity 102, and the small circle of the second support portion 22c abuts against the cymba conchae 103. Of course, the curvature of the two ends of the first support portion 21c and the second support portion 22c that are set opposite to each other can also be set to be the same; or the curvature of the end of the first support portion 21c can be smaller than the curvature of the end of the second support portion 22c.

[0103] It should be noted that no matter what shape the wearing structure 20 takes, as long as the arrangement and function of its first support part 21 and second support part 22 are the same as those described in this specification, it belongs to the scheme to be protected by the embodiments of this application.

[0104] In some embodiments, such as Figure 15 As shown, the wearing structure 20 may include the following design parameters: Along the first horizontal direction (X2 axis direction), the distance a between the longitudinal centerline and the endpoint of the first support 21; Along the first vertical direction (Y2 axis direction), the distance b between the horizontal centerline and the lower end point of the first support 21; Along the first vertical direction (Y2 axis direction), the distance c between the transverse centerline and the upper end point of the second support 22; The distance d between the longitudinal centerline and the endpoint of the second support 22 along the first horizontal direction (X2 axis direction); The first horizontal direction (X2 axis direction) and the first vertical direction (Y2 axis direction) can both be based on the wearing state of the wearing structure 20: the first vertical direction (X2 axis direction) can be set as the height direction of the auricle 100, and the first horizontal direction (X2 axis direction) can be set as perpendicular to the first vertical direction (Y2 axis direction) and coplanar with the side of the wearing structure 20 facing the auricle 100; The longitudinal centerline can be set to pass through the center O of the sound transmission hole 31 and be parallel to the first vertical direction (Y2 axis direction), and the transverse centerline can be set to pass through the center O and be parallel to the first horizontal direction (X2 axis direction).

[0105] Understandably, the above design parameters are set in a coordinated manner, each with a set numerical range, and they influence and coordinate with each other so that the wearing structure 20 can fit comfortably, securely, and comfortably into the concha 102 and concha 103.

[0106] In some embodiments, the range of a can be 7mm~15mm; the range of b can be 3mm~12mm; the range of c can be 10mm~20mm; and the range of d can be 10mm~20mm. Understandably, when a, b, c, and d are simultaneously within their respective numerical ranges, the wearing structure 20 as a whole has a relatively adaptable deformation capability. When the wearing structure 20 is in the wearing state, the first support portion 21 can adaptively deform according to the force applied and the different contours of the user's concha 102 to adapt, and can be securely and comfortably abutted within the concha 102; simultaneously, the second support portion 22 can adaptively deform and bend according to the force applied and the different contours of the user's cymba concha 103 to adapt, and can be securely and comfortably abutted within the cymba concha 103.

[0107] Preferably, at least one of a, b, c, and d satisfies the following corresponding range: The range of a can be 8mm~12mm; the range of b can be 5mm~8mm; the range of c can be 15mm~18mm; the range of d can be 15mm~18mm.

[0108] In some specific embodiments, the value of a can be 9mm; the value of b can be 6mm; the value of c can be 15mm; and the value of d can be 15mm. The wearing structure 20 produced based on the aforementioned specific parameters can be securely and comfortably fitted into the user's auricle 100.

[0109] Understandably, based on the numerical ranges of the aforementioned design parameters, the latter numerical ranges represent further optimization. When at least one of a, b, c, and d falls within the corresponding numerical range of the latter, the overall adaptability of the wearing structure 20 is further improved. Thus, when the wearing structure 20 is in the wearing state, the first support 21 can adaptively deform according to the force applied and the different contours of the user's concha 102 to adapt, and can be further securely and comfortably locked within the concha 102; simultaneously, the second support 22 can adaptively deform and bend according to the force applied and the different contours of the user's sclera 103 to adapt, and can be further securely and comfortably locked within the sclera 103. The more items (a, b, c, d) that satisfy the corresponding numerical ranges of the latter, the higher the adaptability of the wearing structure 20.

[0110] In some embodiments, such as Figure 16 As shown, based on the cross-section of the first support portion 21 in the horizontal plane (X3Y3 plane), the cross-section may include an upper end face and a lower end face respectively disposed in the second vertical direction (Y3 axis direction). Specifically, the upper end face of the cross-section may be configured as the side of the first support portion 21 facing the open end, and the lower end face of the cross-section may be configured as the side of the first support portion 21 away from the open end. The lower end face may be planar, and the upper end face may be an arc surface concave to the lower end face. Along the second horizontal direction (X3 axis direction), both ends of the lower end face may be bent and extended to both ends of the upper end face to connect with the upper end face and form protrusions.

[0111] With the wearing structure 20 in the wearing state as a reference, the first vertical direction is the height direction of the auricle 100, and the first horizontal direction is the direction perpendicular to the first vertical direction and coplanar with the side of the wearing structure 20 facing the auricle 100. Based on this, the horizontal plane (X3Y3 plane) can be set as the intersection of the first horizontal direction (X-axis direction) and the vertical direction, the vertical direction can be set as the direction perpendicular to the intersection of the first horizontal direction (X-axis direction) and the first vertical direction (Y-axis direction), and the second horizontal direction (Y3-axis direction) can be set as the width direction of the cross-section on the horizontal plane (X3Y3 plane). Of course, the cross-section of the first support part 21 can also be set to other shapes, which will not be elaborated on here.

[0112] In some embodiments, such as Figure 15 As shown, the wearing structure 20 may also include the following design parameters: The distance e between the protrusion and the lower end face along the second vertical direction (Y3 axis direction); Along the second vertical direction (Y3 axis direction), the distance e1 between the lowest point of the upper end face and the lower end face; The distance e2 between the two ends of the cross section along the second horizontal direction (X3 axis direction); The second vertical direction (Y3 axis direction) can be set as the height direction of the cross section on the horizontal plane (X3Y3 plane).

[0113] Understandably, the above design parameters are set in a coordinated manner, each with a set numerical range, and they influence and coordinate with each other so that the wearing structure 20 can fit comfortably, securely, and comfortably into the concha 102 and concha 103.

[0114] In some embodiments, e ranges from 1 to 5 mm; e1 ranges from 0.5 to 0.8e; and e2 ranges from 1 to 7 mm. Understandably, when e, e1, and e2 are simultaneously within their respective numerical ranges, the wearing structure 20 as a whole has a relatively adaptable deformation capability and adapts to the contact surface of the concha 102. This allows the first support portion 21 of the first support portion 21 to deform and fit against the contact surface of the concha 102 when the wearing structure 20 is in the wearing state, and to be securely and comfortably abutted within the concha 102.

[0115] Preferably, at least one of e and e2 satisfies the following corresponding range: The range of e is 1.5~2mm; the range of e2 is 3~5mm.

[0116] In some specific embodiments, the value of e is 2mm; the value of e1 is 1.2mm; and the value of e2 is 3.5mm. The wearing structure 20 produced based on the aforementioned specific parameters can be securely and comfortably fitted into the user's auricle 100, and can effectively reduce the presence of the first support 21 in the concha cavity 102.

[0117] Understandably, based on the numerical ranges of the aforementioned design parameters, the latter numerical ranges represent further optimization. When at least one of e and e2 falls within the corresponding numerical range of the latter, the overall deformation of the wearing structure 20 and the fit between the first support 21 and the contact surface of the concha 102 are further improved. The more items of e and e2 that satisfy the corresponding numerical ranges of the latter, the higher the overall deformation of the wearing structure 20 and the fit between the first support 21 and the contact surface of the concha 102.

[0118] In some embodiments, the shape of the end of the first support portion 21 away from the second support portion 22 is not limited to... Figure 17 As shown, there are many other variations. Combined with... Figure 17 The figure shows various alternative cross-sections of the first support portion 21 at point BB (essentially alternative shapes of the first support portion 21), including but not limited to the following: As shown in Figure (a), the upper and lower surfaces of the first support portion 21 can both be horizontally arranged; as shown in Figure (b), the upper and lower surfaces of the first support portion 21 protrude in opposite directions to make the cross-section elliptical; as shown in Figure (c), the upper and lower surfaces of the first support portion 21 are slightly concave downwards, giving the overall shape a downward arched shape; as shown in Figure (d), the upper surface of the first support portion 21 is concave towards the lower surface, and the lower surface is concave towards the upper surface, giving the overall shape a bow-like shape; as shown in Figure (e), the upper surface of the first support portion 21 is horizontally arranged, and the middle of the lower surface protrudes downwards, giving the overall shape an isosceles inverted triangle.

[0119] In some embodiments, such as Figure 18 As shown, the headphone body 10 may further include a housing, an energy storage device 12, a circuit board 13, and a charging structure 14. The energy storage device 12, the circuit board 13, and the charging structure 14 may all be disposed within the housing. The charging structure 14 may be disposed within the housing and at least partially exposed outside the housing. The transducer 11, the energy storage device 12, and the charging structure 14 are all electrically connected to the circuit board 13.

[0120] Optionally, the energy storage device 12 may be a battery or a battery pack, etc.

[0121] Optionally, the circuit board 13 may be a rigid circuit board or a flexible circuit board, etc.

[0122] Optionally, the charging structure 14 may include a charging interface, typically a Type-C interface or a Lightning Dock interface, for charging and data transfer.

[0123] In addition, the earphone body 10 also includes, but is not limited to: a Bluetooth chip, responsible for wireless connection and signal transmission; providing power to the earphone 200; a microphone, used for calls and voice input; and indicator lights, used to provide feedback on the status of the earphone 200, such as charging status and pairing status.

[0124] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
