Description

Technical Field

[0001] This application relates to the technical field of wireless earphones, and particularly to an ear-hooking earphone. Background Art

[0002] Currently, earphones on the market are divided into two categories, namely in-ear earphones and non-in-ear earphones. Since in-ear earphones need to insert the sound outlet holes of the earphones into the ear canals, wearing in-ear earphones is likely to cause damage to the eardrums, thereby resulting in hearing loss. Non-in-ear earphones are divided into over-ear earphones and ear-hooking earphones. Over-ear earphones occupy a large space and have a large size, making them inconvenient to carry and store. Ear-hooking earphones are favored by consumers because of their small and beautiful shape. It is easy to understand that due to different ages, genetic factors, and growth environments, there will be differences in the shape and size of the auricles. Currently, the length of the existing ear-hooking earphones cannot be adjusted, so they cannot compensate for or overcome the adverse effects brought by auricle differences, resulting in different experiences for people when wearing the same ear-hooking earphones. For example, for some people, the distance between the sound outlet hole and the eardrum is moderate after wearing the ear-hooking earphone, while for others, the distance between the sound outlet hole and the eardrum is relatively far after wearing the same ear-hooking earphone, resulting in a relatively small earphone sound, or the distance between the sound outlet hole and the eardrum is relatively close, resulting in a relatively large earphone sound, which seriously affects the user experience. Utility Model Content

[0003] To solve the above problems, this application provides an ear-hooking earphone, which is ingeniously designed and has a simple structure. By setting a telescopic component, the distance between the earphone head and the end of the connecting piece can be adjusted, thereby realizing the adjustment of the distance between the earphone head and the ear canal, enabling the earphone to adapt to users with different auricle shapes and sizes. In addition, by setting an ear clip package, the clamping effect of the earphone can be improved, the risk of the earphone falling off the ear can be reduced, and the adaptability of the earphone to the user's movement can be enhanced. In addition, the ear clip package and the earphone head are respectively arranged at both ends of the connecting piece, which can appropriately distribute the overall weight of the earphone in front of and behind the ear, increase the stability of wearing the earphone, and improve the wearing experience. The technical solutions adopted in this application are as follows:

[0004] An ear-hooking earphone, comprising:

[0005] A bent connecting piece; an earphone head, the earphone head is connected to one end of the connecting piece through a telescopic component; an ear clip package, the ear clip package is rotatably connected to the end of the connecting piece far from the earphone head; the earphone head, the connecting piece, and the ear clip package enclose an ear-hooking space.

[0006] By setting the telescopic component, the distance between the headphone head and the end of the connecting piece can be adjusted, thereby adjusting the distance between the headphone head and the ear canal, enabling the headphones to adapt to users with different auricle shapes and sizes. In addition, by setting the ear clip holder, the clamping effect of the headphones can be improved, reducing the risk of the headphones falling off the ears and enhancing the adaptability of the headphones to the user's movement. Additionally, the ear clip holder and the headphone head are respectively arranged at both ends of the connecting piece, which can appropriately distribute the overall weight of the headphones in front of and behind the ear, increasing the stability of wearing the headphones and enhancing the wearing experience.

[0007] In some embodiments, the telescopic component includes an inner shaft and an outer cylinder. One end of the inner shaft is connected to the connecting piece, the outer cylinder is sleeved outside the inner shaft, and the end of the outer cylinder away from the connecting piece is connected to the headphone head. The inner shaft and the outer cylinder can slide relative to each other; a flange is provided on the outside of the inner shaft, and the end of the outer cylinder close to the connecting piece is a stepped hole. The flange is adapted to abut against the shoulder of the stepped hole to prevent the outer cylinder from detaching from the inner shaft.

[0008] By setting the flange and the stepped hole, when the flange abuts against the shoulder of the stepped hole, the flange limits the inner shaft, preventing the inner shaft and the outer cylinder from detaching, and at the same time controlling the maximum elongation distance of the telescopic component.

[0009] In some embodiments, an anti-twist mechanism is provided between the inner shaft and the outer cylinder, and the anti-twist mechanism is used to limit the relative rotation between the inner shaft and the outer cylinder.

[0010] By setting the anti-twist mechanism, relative rotation between the inner shaft and the outer cylinder can be avoided during the telescoping process of the telescopic component, ensuring that the posture of the headphone head does not change.

[0011] In some embodiments, a raised portion is provided on the outside of the inner shaft, and a sliding groove adapted to the raised portion is provided on the inside of the outer cylinder. The sliding groove extends along the length direction of the outer cylinder, and the raised portion and the sliding groove form the anti-twist mechanism.

[0012] By arranging the raised portion on the inner shaft and the sliding groove on the inside of the outer cylinder, compared with arranging the raised portion on the inside of the outer cylinder and the sliding groove on the outside of the inner shaft, the processing and production difficulty of the outer cylinder can be reduced, such as facilitating the mold opening and demolding of the outer cylinder, and at the same time reducing the requirement for the thickness of the inner shaft.

[0013] In some embodiments, an O-ring is clamped between the inner shaft and the outer cylinder.

[0014] By setting the O-ring, the O-ring can provide damping for the relative sliding between the inner shaft and the outer cylinder, enabling the outer cylinder and the inner shaft to remain in any relative position, that is, the outer cylinder can stay in any position relative to the inner shaft, realizing stepless adjustment of the telescopic length of the telescopic component.

[0015] In some embodiments, a ring groove is provided on the outer side of the inner shaft, and the O-ring is sleeved in the ring groove.

[0016] By providing the ring groove, the O-ring can be limited in position, preventing the O-ring from moving when the inner shaft and the outer cylinder slide relative to each other, thereby improving the smoothness of the relative sliding between the inner shaft and the outer cylinder and ensuring the user experience.

[0017] In some embodiments, a groove is provided on the outer side of one end of the inner shaft close to the connecting member, and the connecting member is connected to the outer side of the part of the inner shaft provided with the groove by a rubber coating process.

[0018] By providing the groove and adopting the rubber coating process, the connection strength between the inner shaft and the connecting member can be improved, and the risk of detachment between the inner shaft and the connecting member can be reduced.

[0019] In some embodiments, the maximum telescopic length of the telescopic assembly is not greater than 4 mm.

[0020] By controlling the maximum telescopic length of the telescopic assembly within a range not greater than 4 mm, the clamping and wearing needs of most people can be met, and at the same time, the influence on the bending smoothness of the connecting member caused by too long maximum telescopic length can be reduced.

[0021] In some embodiments, the ear clip package is rotatably connected to the connecting member through a rotating shaft, and a torsion spring is provided on the rotating shaft so that the ear clip package can clamp the ear.

[0022] By providing a torsion spring on the rotating shaft, after the ear clip package rotates, the torsion spring generates torsional deformation, so that the ear clip package has a tendency to reset, thereby clamping the ear and preventing the earphone from falling off the ear.

[0023] In some embodiments, when the ear clip package is in the initial position, the minimum gap between the ear clip package and the earphone head is 2 to 4 mm, and when the ear clip package rotates to the limit position, the maximum gap between the ear clip package and the earphone head is 7 to 9 mm.

[0024] By controlling the minimum gap between the ear clip package and the earphone head within the range of 2 - 4 mm and the maximum gap between the ear clip package and the earphone head within the range of 7 - 9 mm, the clamping and wearing needs of most people can be met.

[0025] The ear-clamping type earphone provided by the present application has at least one of the following beneficial effects:

[0026] 1. An earclip-type earphone provided by the present application can adjust the distance between the earphone head and the end of the connecting member by setting a telescopic component, thereby adjusting the distance between the earphone head and the ear canal, enabling the earphone to adapt to users with different auricle shapes and sizes. In addition, by setting an earclip, the clamping effect of the earphone can be improved, the risk of the earphone falling off the ear can be reduced, and the adaptability of the earphone to the user's movement can be enhanced. Moreover, the earclip and the earphone head are respectively arranged at both ends of the connecting member, which can appropriately distribute the overall weight of the earphone in front of and behind the ear, increasing the stability of wearing the earphone and improving the wearing experience.

[0027] 2. An earclip-type earphone provided by the present application can limit the inner shaft by setting a flange and a stepped hole when the flange abuts against the shoulder of the stepped hole, preventing the inner shaft from separating from the outer cylinder and also controlling the maximum elongation distance of the telescopic component.

[0028] 3. An earclip-type earphone provided by the present application can avoid the relative rotation between the inner shaft and the outer cylinder during the telescopic process of the telescopic component by setting an anti-twist mechanism, ensuring that the posture of the earphone head does not change.

[0029] 4. An earclip-type earphone provided by the present application sets the convex portion on the inner shaft and the sliding groove on the inner side of the outer cylinder. Compared with setting the convex portion on the inner side of the outer cylinder and the sliding groove on the outer side of the inner shaft, it can reduce the processing and production difficulty of the outer cylinder, such as facilitating the mold opening and demolding of the outer cylinder, and at the same time, it can also reduce the requirement for the thickness of the inner shaft.

[0030] 5. An earclip-type earphone provided by the present application can provide damping for the relative sliding between the inner shaft and the outer cylinder by setting an O-ring, enabling the outer cylinder and the inner shaft to remain in any relative position, that is, the outer cylinder can stay in any position relative to the inner shaft, realizing stepless adjustment of the telescopic length of the telescopic component.

[0031] 6. An earclip-type earphone provided by the present application can limit the O-ring by setting an annular groove, avoiding the O-ring from moving when the inner shaft and the outer cylinder slide relative to each other, thereby improving the smoothness of the relative sliding between the inner shaft and the outer cylinder and ensuring the user experience.

[0032] 7. An earclip-type earphone provided by the present application can improve the connection strength between the inner shaft and the connecting member and reduce the risk of separation between the inner shaft and the connecting member by setting a groove and adopting a rubber coating process.

[0033] 8. An earclip-type earphone provided by the present application can control the maximum telescopic length of the telescopic component within a range not greater than 4 mm, which can meet the clamping needs of most people and at the same time reduce the impact on the bending smoothness of the connecting member caused by too long maximum telescopic length.

[0034] 9. An earclip-type earphone provided by the present application is provided with a torsion spring on the rotating shaft. After the earclip package rotates, the torsion spring generates torsional deformation, so that the earclip package has a reset tendency, thereby clamping the ear and preventing the earphone from falling off the ear.

[0035] 10. An earclip-type earphone provided by the present application can meet the clamping and wearing needs of most people by controlling the minimum gap between the earclip package and the earphone head within the range of 2-4 mm and the maximum gap between the earclip package and the earphone head within the range of 7-9 mm.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0047] To more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will describe the specific implementation manners of the present application with reference to the accompanying drawings. Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other implementation manners can also be obtained.

[0048] To make the drawings concise, only the parts related to the present application are schematically shown in each drawing, and they do not represent the actual structure of the product. Additionally, to make the drawings concise and easy to understand, in some drawings, for components with the same structure or function, only one of them is schematically shown, or only one of them is labeled. In this document, "one" not only means "only this one" but also means "more than one" situation.

[0049] It should also be further understood that the term "and / or" used in the description of the present application and the appended claims refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0050] In this document, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0051] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0052] Referring to Figures 1-5 , the present application provides a clip-on earphone, including: a bent connecting member 1, an earphone head 3, and an ear clip 4; the earphone head 3 is connected to one end of the connecting member 1 through a telescopic assembly, and the ear clip 4 is rotatably connected to the other end of the connecting member 1; the telescopic assembly includes an inner shaft 5 and an outer cylinder 6, one end of the inner shaft 5 is connected to the connecting member 1, the outer cylinder 6 is sleeved outside the inner shaft 5, the end of the outer cylinder 6 away from the connecting member 1 is connected to the earphone head 3, and the inner shaft 5 and the outer cylinder 6 can slide relative to each other; a flange 7 is provided on the outside of the inner shaft 5, and the end of the outer cylinder 6 close to the connecting member 1 is a stepped hole 8. When the flange 7 abuts against the shoulder 9 of the stepped hole 8, the flange 7 limits the inner shaft 5 to prevent the inner shaft 5 from separating from the outer cylinder 6, and at the same time, the maximum elongation distance of the telescopic assembly is also controlled.

[0053] It can be understood that by setting the telescopic component, the distance between the headphone head 3 and the end of the connecting member 1 can be adjusted, thereby realizing the adjustment of the distance between the headphone head 3 and the ear canal, enabling the headphones to adapt to users with different ear shapes and sizes. In addition, by setting the ear clip 4, the clamping effect of the headphones can be improved, the risk of the headphones falling off the ears can be reduced, and the adaptability of the headphones to the user's movement can be enhanced. In addition, the ear clip 4 and the headphone head 3 are respectively arranged at both ends of the connecting member 1, which can appropriately distribute the overall weight of the headphones in front of and behind the ear, increasing the stability of wearing the headphones and enhancing the wearing experience.

[0054] It should be noted that the components of the headphones can be all arranged in the headphone head 3, or distributed in the headphone head 3 and the ear clip 4. Preferably, components are provided in both the headphone head 3 and the ear clip 4, and a wire harness 2 is provided in the connecting member 1. The wire harness 2 electrically connects the components in the headphone head 3 and the components in the ear clip 4. It is easy to understand that in this embodiment, the inner shaft 5 is provided with a perforation, and the wire harness 2 is adapted to pass through the perforation.

[0055] Reference Figures 6-8 , in this embodiment, the inner shaft 5 is connected to the connecting member 1, and the outer cylinder 6 is connected to the headphone head 3. In other embodiments, the inner shaft 5 can be connected to the headphone head 3, and the outer cylinder 6 can be connected to the connecting member 1. In the embodiment where the inner shaft 5 is connected to the connecting member 1, the inner shaft 5 and the connecting member 1 can be connected by hot melt welding, or the end of the inner shaft 5 can be embedded in the end of the connecting member 1 by a rubber coating process (overmolding process, two-shot injection molding process), or the end of the connecting member 1 can be embedded in the end of the inner shaft 5 in the future. Reference Figures 6-8 , in order to control the size of the inner shaft 5, it is preferred to embed one end of the inner shaft 5 into one end of the connecting member 1. It is easy to understand that in order to ensure the connection strength between the inner shaft 5 and the connecting member 1 and reduce the risk of detachment between the inner shaft 5 and the connecting member 1, in one embodiment, a groove 14 is provided on the outer side of the end of the inner shaft 5 close to the connecting member 1, and the connecting member 1 is connected to the outer side of the part of the inner shaft 5 provided with the groove 14 by a rubber coating process.

[0056] It is easy to understand that, referring to Figures 3-8 , in order to prevent relative rotation (rotation) between the inner shaft 5 and the outer cylinder 6 during relative sliding, an anti-twist mechanism can be provided between the inner shaft 5 and the outer cylinder 6. The anti-twist mechanism includes a protrusion 10 provided on the outer side of the inner shaft 5 and a chute 11 provided on the inner side of the outer cylinder 6. The protrusion 10 and the chute 11 are adapted to each other. Obviously, the chute 11 extends along the length direction of the outer cylinder 6. By providing the anti-twist mechanism, relative rotation between the inner shaft 5 and the outer cylinder 6 can be avoided during the telescopic process of the telescopic component, thereby avoiding damage or detachment of the wire harness 2 and the components connected by the wire harness 2 due to torsion, and at the same time ensuring that the posture of the headphone head 3 does not change.

[0057] In this embodiment, the convex portion 10 is provided on the inner shaft 5, while the sliding groove 11 is provided on the outer cylinder 6. In other embodiments, the installation positions of the convex portion 10 and the sliding groove 11 can be swapped. That is to say, the sliding groove 11 can be provided on the outside of the inner shaft 5, and the convex portion 10 can be provided on the inside of the outer cylinder 6. However, this will increase the production and processing difficulty of the outer cylinder 6. For example, since the convex portion 10 is provided on the inside of the outer cylinder 6, the mold opening difficulty and demolding difficulty of the outer cylinder 6 are increased, and the injection molding quality of the outer cylinder 6 is not easy to control. In addition, when the sliding groove 11 is provided on the outside of the inner shaft 5, requirements are also put forward for the thickness of the inner shaft 5 to ensure the depth of the sliding groove 11. In addition, when the size of the connecting member 1 is fixed, when the connecting member 1 is coated on one end of the inner shaft 5 by the overmolding process, the larger the size of the inner shaft 5, that is, the larger the outer diameter of the inner shaft 5, the smaller the thickness of the coating layer of the connecting member 1 coated on the outside of the inner shaft 5. This reduces the connection strength between the connecting member 1 and the inner shaft 5 and increases the risk of fracture at the connection between the connecting member 1 and the inner shaft 5.

[0058] In order to have damping when the inner shaft 5 and the outer cylinder 6 slide relative to each other, so that the outer cylinder 6 and the inner shaft 5 can be maintained at any relative position, that is to say, the outer cylinder 6 can stay at any position relative to the inner shaft 5. Refer to Figures 3-8 , in one embodiment, an O-ring 12 is clamped between the inner shaft 5 and the outer cylinder 6. By providing the O-ring 12, stepless adjustment of the telescopic length of the telescopic assembly is achieved. It is easy to understand that if the O-ring 12 is not fixed or limited, the risk of the O-ring 12 moving around when the inner shaft 5 and the outer cylinder 6 slide relative to each other is relatively high. The movement of the O-ring 12 will reduce the smoothness when the inner shaft 5 and the outer cylinder 6 slide relative to each other. To prevent the O-ring 12 from moving around, a ring groove 13 can be provided on the outside of the inner shaft 5, and the O-ring 12 is sleeved in the ring groove 13, or the ring groove 13 can be provided on the inside of the outer cylinder 6, and the O-ring 12 is clamped in the ring groove 13. It is easy to understand that the difficulty of providing the ring groove 13 on the inner shaft 5 is less than that of providing the ring groove 13 on the outer cylinder 6. It should be noted that the damping between the inner shaft 5 and the outer cylinder 6 can also be provided by the interference fit between the outer wall of the inner shaft 5 and the inner wall of the outer cylinder 6, or by the interference fit between the convex portion 10 and the sliding groove 11, or by the interference fit between the flange 7 and the inner wall of the outer cylinder 6, or by the interference fit between the stepped hole 8 and the outer wall of the inner shaft 5.

[0059] Refer to Figures 1-4, in one embodiment, the ear clip package 4 is rotatably connected to the connecting member 1 through a rotating shaft 15, and a torsion spring 16 is provided on the rotating shaft 15. After the ear clip package 4 rotates, the torsion spring 16 undergoes torsional deformation, causing the ear clip package 4 to have a reset tendency, thereby clamping the ear and preventing the earphone from falling off the ear. In other embodiments, the ear clip package 4 is rotatably connected to the connecting member 1 through a rotating shaft 15, and the rotating shaft 15 is a damping rotating shaft. By using a damping rotating shaft, the ear clip package 4 can stay at any angular position, that is, the clamping degree of the earphone can be adjusted by adjusting the rotation angle of the ear clip package 4 to meet the clamping degree requirements of different users. It can be understood that when it is necessary to limit the maximum rotation angle of the ear clip package 4, it can be achieved by setting a limiting mechanism. For example, one end of the connecting member 1 connecting the ear clip package 4 is provided with a flared opening (or a fan-shaped opening), and the wire harness 2 passes through the flared opening. The wire harness 2 can only bend within the opening range of the flared opening, thereby limiting the maximum rotation angle of the ear clip package 4. By adjusting the opening range of the flared opening, the maximum rotation angle of the ear clip package 4 can be adjusted.

[0060] Reference Figure 7 、 Figure 8 , in one embodiment, the maximum telescopic length A of the telescopic assembly is between 0 and 4 mm. By controlling the maximum telescopic length of the telescopic assembly within a range not greater than 4 mm, the clamping and wearing requirements of most people can be met. At the same time, the influence on the bending smoothness of the connecting member 1 caused by too long a maximum telescopic length can be reduced, and the length of the wire harness 2 stored in the earphone head 3 can also be reduced.

[0061] In one embodiment, reference Figure 6 、 Figure 7 , when the ear clip package 4 is in the initial position, the minimum gap B between the ear clip package 4 and the earphone head 3 is 2 to 4 mm, and when the ear clip package 4 rotates to the limit position, the maximum gap C between the ear clip package 4 and the earphone head 3 is 7 to 9 mm. By controlling the minimum gap B between the ear clip package 4 and the earphone head 3 within the range of 2 - 4 mm, and the maximum gap C between the ear clip package 4 and the earphone head 3 within the range of 7 - 9 mm, the clamping and wearing requirements of most people can be met.

[0062] It should be noted that the above embodiments can be freely combined as needed. The above are only the preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
