Description

Technical Field

[0001] The present invention relates to the technical field of earphones, and in particular to a clip-on earphone. Background Art

[0002] The clip-on earphone is clamped on the helix for use. Compared with in-ear earphones, the clip-on earphone does not invade the ear canal. Therefore, its structure can reduce the risk of the user suffering from otitis media induced by long-term wearing. Thus, the application of clip-on earphones is becoming more and more extensive.

[0003] The existing clip-on earphones include an outer ear earphone component, an inner ear earphone component and a bridge. The bridge is in a C-shaped curved structure, and the outer ear earphone component and the inner ear earphone component are roughly in a bean-shaped circular structure and are respectively connected to both ends of the bridge. A clamping gap is formed between the outer ear earphone component and the inner ear earphone component. When in use, the earphone is clamped on the ear at the clamping gap, so as to realize wearing the earphone. However, since the outer ear earphone component, the inner ear earphone component and the bridge in the clip-on earphone are basically fixedly connected and non-detachable, after the earphone is produced, the clamping gap between the outer ear earphone component and the inner ear earphone component is basically fixed. However, due to certain differences in the ear structures among different users, the same earphone clamping gap may not be applicable to different users. Therefore, it is difficult for the existing clip-on earphones to adjust the earphone clamping gap according to the actual situation to be applicable to different users, that is, it cannot adapt to different ear structures during wearing. Especially for users with different ear thicknesses, the wearing difference is particularly obvious. It cannot provide a stable and comfortable wearing experience for the differences in the auricle shapes of each person, and there is a sense of foreign body during wearing. Uncomfortable feelings may occur after long-term wearing. Moreover, it is difficult for the user to adjust the earphone state according to the usage situation to achieve the maximum wearing comfort. There are also some that achieve the purpose of adjusting the clamping gap by setting the bridge as a soft bridge with a certain elastic deformation. However, it is limited by the limited elastic deformation of the bridge and the limited axial distance of the bridge, resulting in a small expansion and contraction range of the bridge distance.

[0004] Therefore, it is necessary to research a new technology to solve the above problems. Summary of the Invention

[0020] The specific implementation manner of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific implementation manner described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0021] Please refer to Figures 1 to 14 As shown, this embodiment provides an earclip-type earphone, including an outer earphone member 10, an inner earphone member 20 and a bridge. The outer earphone member 10 and the inner earphone member 20 are respectively connected to both ends of the bridge. A clamping gap 101 is formed between the outer earphone member 10 and the inner earphone member 20; the bridge includes a bridge main body 30 and a sliding arm 40 detachably connected to one end of the bridge main body 30. The inner earphone member 20 is connected to the other end of the bridge main body 30, and the bridge main body 30 is in an arc-shaped structure; in this embodiment, the bridge main body 30 is a silicone member and is bent on the side close to the sliding arm 40 to form an elastic arc-shaped structure; a first sliding portion extending obliquely relative to the clamping gap 101 is provided on the sliding arm 40, and a second sliding portion is connected to the end of the outer earphone member 10 facing the sliding arm 40. The second sliding portion is slidably connected to the first sliding portion; as the second sliding portion slides relative to the first sliding portion, the outer earphone member 10 moves along the extension direction of the first sliding portion, so that the outer earphone member 10 approaches or moves away from the inner earphone member 20, and the end of the outer earphone member 10 facing the sliding arm 40 approaches or moves away from the end of the bridge main body 30. In this way, the relative positions of the outer earphone member 10 and the inner earphone member 20 can be changed, so that the size of the clamping gap 101 between the outer earphone member 10 and the inner earphone member 20 can be adjusted. Moreover, the sliding arm 40 and the arc-shaped bridge main body 30 cooperate to form the entire bridge, and a first sliding portion extending obliquely is provided on the sliding arm 40. The end of the outer earphone member 10 facing the sliding arm 40 can approach or move away from the end of the bridge main body 30, which can increase the expansion and contraction range of the distance of the earphone bridge, obtain more activity space, and make its compatibility with different auricle sizes and shapes better. It can make the earphone better adapt to the user's ears. The user can adjust the clamping gap 101 according to their own needs, thereby improving the wearing comfort. At the same time, the applicable range of the earphone can be increased, giving consumers a better use experience. And its structure is simple, reliable, and the manufacturing cost is low.

[0022] Either the first sliding part or the second sliding part is set as the sliding groove 50, and the other is set as the sliding block 60; the sliding block 60 is slidably connected to the sliding groove 50. In this embodiment, the first sliding part is the sliding groove 50; the sliding groove 50 is recessed in the inner side of the sliding arm 40 facing the clamping gap 101 and extends along the length direction of the sliding arm 40; the second sliding part is the sliding block 60 and protrudes from one end of the outer earpiece 10 facing the sliding arm 40.

[0023] In this embodiment, specifically, the sliding groove 50 includes a first groove part 51 and a second groove part 52; the first groove part 51 is recessed inward from the inner side of the sliding arm 40 facing the clamping gap 101 and extends along the length direction of the sliding arm 40; second groove parts 52 are recessed on both inner side walls in the width direction of the first groove part 51, and the second groove parts 52 extend along the length direction of the first groove part 51; the sliding block 60 includes a main body part 61 and a sliding convex part 62 integrally connected to one end of the main body part 61, the sliding convex part 62 extends obliquely upward and outward, the other end of the main body part 61 is connected to one end of the outer earpiece 10 facing the sliding arm 40, the sliding convex part 62 protrudes outside one end of the outer earpiece 10 facing the sliding arm 40, and convex blocks 63 are protruded on both side walls in the width direction of the sliding convex part 62; the sliding convex part 62 is slidably adapted in the first groove part 51, and the convex blocks 63 are slidably adapted in the second groove parts 52. Also, the structure of the convex blocks 63 corresponds to that of the second groove parts 52. After the sliding block 60 and the sliding groove 50 are matched, the side of the convex block 63 close to the main body part 61 is limited by the lower inner wall of the second groove part 52, that is, the structure of the sliding groove 50 can limit and fix the structure of the sliding block 60, thereby preventing the sliding block 60 from falling off from the sliding groove 50 and ensuring a stable connection between the sliding arm 40 and the outer earpiece 10.

[0024] In this embodiment, a damping member 70 is provided on the top of the sliding convex portion 62. The damping member 70 is preferably made of silica gel material. The side of the damping member 70 away from the sliding convex portion 62 is in frictional contact with the inner top wall of the first groove portion 51. When the sliding block 60 moves, friction is generated by the contact between the damping member 70 and the inner top wall of the first groove portion 51, which can provide a suitable sliding feel for the movement of the sliding block 60, and can keep the sliding block 60 stable after moving to any position, and can enable the user to adjust the headphone clamping gap 101 with one hand operation. In this embodiment, an embedding groove 64 is recessed in the top of the sliding convex portion 62, the damping member 70 is embedded in the embedding groove 64, and the top of the damping member 70 is exposed outside the top of the sliding convex portion 62. Preferably, the embedding groove 64 extends to the top of the convex block 63. Correspondingly, a part of the damping member 70 is exposed outside the top of the convex block 63 to be in frictional contact with the inner top wall of the second groove portion 52, further enhancing the frictional resistance of the damping member 70. When it is necessary to adjust the clamping gap 101, by applying a force greater than the frictional force by the user, the outer ear headphone member 10 is pushed, so that the sliding block 60 can move on the sliding arm 40, thereby adjusting the clamping gap 101 between the outer ear headphone member 10 and the inner ear headphone member 20, and keeping the outer ear headphone member 10 stable through the damping member 70 after adjusting to the corresponding position.

[0025] In this embodiment, a baffle 65 is integrally convexly provided on the side of the sliding convex portion 62 facing the bridge body 30. The baffle 65 extends along the length direction of the first groove portion 51. A relief groove 41 communicating with the first groove portion 51 is recessed inside the sliding arm 40. The relief groove 41 is provided on the side of the first groove portion 51 facing the bridge body 30 and extends along the length direction of the first groove portion 51. As the sliding block 60 slides relative to the sliding groove 50, the baffle 65 is blocked in the opening on the side of the first groove portion 51 facing the clamping gap 101, or the baffle 65 moves into the relief groove 41. When the sliding block 60 moves to the bottom of the sliding arm 40, the baffle 65 can block the first groove portion 51 on the sliding arm 40 to achieve a dust-proof effect, and can block the exposed wire 104 inside the sliding arm 40 to improve the aesthetic requirements of the product.

[0026] In this embodiment, the sliding block 60 has a hollow cavity 66 for the wire 104 to pass through. Both ends of the hollow cavity 66 communicate with the first groove portion 51 and the outer ear headphone member 10 respectively. The opening of the hollow cavity 66 facing the first groove portion 51 is a flared opening 67. The included angle between the flared opening 67 and the first groove portion 51 is a right angle. In this way, during the sliding process, the flared opening 67 cooperates with the hollow cavity 66 to accommodate the coiled wire 104, preventing the phenomenon of poor sliding feel caused by the knotting and curling of the wire 104. In this embodiment, the flared opening 67 penetrates to the bottom of the embedding groove 64 and penetrates to the side of the sliding convex portion 62 close to the baffle 65.

[0027] In this embodiment, a positioning cavity 11 is recessed at one end of the outer earpiece 10 facing the sliding arm 40. A limiting block 12 is protruded on the inner sidewall of the positioning cavity 11. A limiting groove 68 is recessed on the outer sidewall at the other end of the main body portion 61. The other end of the main body portion 61 is positioned in the positioning cavity 11, and the limiting block 12 is positioned in the limiting groove 68.

[0028] In this embodiment, a first stop portion and a second stop portion are respectively arranged on both sides of the first sliding portion along the sliding direction on the sliding arm 40; as the second sliding portion slides relative to the first sliding portion, both sides of the second sliding portion are respectively limited by the first stop portion and the second stop portion. Specifically, the first stop portion is a stop block 80. The stop block 80 is detachably inserted into one end of the sliding arm 40 away from the bridge main body 30. An extension section 42 extends integrally outward from one end of the sliding arm 40 away from the bridge main body 30. The included angle between the extension section 42 and the sliding arm 40 is an obtuse angle. There is a spacing between the extension section 42 and the outer earpiece 10. A plugging cavity 421 is recessed on the side of the extension section 42 facing the outer earpiece 10. Both the first groove portion 51 and the second groove portion 52 communicate with the plugging cavity 421. A docking block 422 is protruded on the inner sidewall of the plugging cavity 421. A plugging hole 423 is recessed on the inner top wall of the plugging cavity 421. A docking groove 81 is recessed on the outer sidewall of the stop block 80. A plugging post 82 is protruded on the top wall of the stop block 80; one end of the stop block 80 is inserted into the plugging cavity 421, and the other end is exposed outside the side of the extension section 42 facing the outer earpiece 10; during assembly, the plugging post 82 is inserted into the plugging hole 423, and the docking block 422 is adapted to the docking groove 81, and then it is detachably fixed on the extension section 42 by screws. When the stop block 80 is removed, the sliding block 60 can be removed from the sliding groove 50 through the plugging cavity 421. In this way, structures such as the sliding block 60 can be disassembled, so as to facilitate the disassembly and installation of the headphone bridge part; the side of the stop block 80 facing the sliding arm 40 is a stop surface 83. An arc-shaped groove 84 is recessed on the stop surface 83. The arc-shaped groove 84 is adapted to the wall surface of the sliding protrusion 62 of the sliding block 60. When the sliding block 60 moves to this position, the arc-shaped groove 84 can play a positioning role to stably place the sliding block 60 here. The second stop portion is a stop wall 43. The stop wall 43 is formed on the inner side of the sliding arm 40 facing the clamping gap 101 and is located on the side of the opening of the first groove portion 51 facing the clamping gap 101 close to the bridge main body 30. In this way, the maximum and minimum positions of the movement of the sliding block 60 can be restricted by the stop block 80 and the stop wall 43, and the stop block 80 can prevent the sliding block 60 from falling off along the sliding direction from the sliding groove 50.

[0029] In this embodiment, the bridge body 30 and the sliding arm 40 are detachably connected by a connecting piece 90. The sliding arm 40 is provided with a connecting hole 44 at one end facing the bridge body 30. The first groove portion 51 and the second groove portion 52 are both connected to the inner bottom wall of the connecting hole 44. The inner side wall of the connecting hole 44 is provided with a first clamping portion. One end of the connecting piece 90 is embedded in one end of the bridge body 30, and the other end of the connecting piece 90 extends out of one end of the bridge body 30. The outer side wall of the other end of the connecting piece 90 A second clamping portion is provided on the side wall, and the other end of the connecting member 90 is inserted into the connecting hole 44; the end face of one end of the bridge frame body 30 abuts against the end face of the sliding arm 40 facing the end of the bridge frame body 30, and the end face of the other end of the connecting member 90 is limited by the inner bottom wall of the connecting hole 44 to prevent the connecting member 90 from being inserted too deeply; the first clamping portion is clamped with the second clamping portion. In the present embodiment, the first clamping portion is a clamping block 45, and the second clamping portion is a clamping groove 91, and the clamping block 45 is clamped in the clamping groove 91.

[0030] In this embodiment, a guide groove 92 is provided on the bottom of the outer side wall of the other end of the connecting member 90. The guide groove 92 extends along the length direction of the clearance groove 41. The clearance groove 41 is formed on the inner side wall of the connecting hole 44. The guide groove 92 and the clearance groove 41 are surrounded by the upper and lower structures to form a groove portion for limiting the baffle 65. The upper and lower parts of the baffle 65 are respectively located in the guide groove 92 and the clearance groove 41. In this way, the combination design of the guide groove 92 and the clearance groove 41 can prevent the sliding block 60 from passing through the baffle 65. The movement on the sliding arm 40 plays a guiding role, which can prevent the sliding block 60 from being offset; and, a stop protrusion 46 is convexly provided on the inner wall of the connecting hole 44 on the side of the make way groove 41 close to the bridge frame body 30, and the end surface of the stop protrusion 46 facing away from the make way groove 41 is flush with the end surface of the sliding arm 40 facing the bridge frame body 30. The stop protrusion 46 is positioned in the guide groove 92 to limit the moving position of the baffle 65 by the setting of the stop protrusion 46.

[0031] In this embodiment, a circuit board 102 and a battery 103 electrically connected to the circuit board 102 are provided in the outer ear earphone 10, and a wire 104 is passed through the bridge body 30; one end of the wire 104 passes through the connecting piece 90, the first groove 51, the trumpet-shaped opening 67, and the hollow cavity 66 in sequence to extend into the outer ear earphone 10 and is electrically connected to the circuit board 102; the other end of the wire 104 extends into the inner ear earphone 20.

[0032] In summary, the key design point of the present invention is that the bridge includes a bridge body and a sliding arm detachably connected to one end of the bridge body. The inner-ear headphone component is connected to the other end of the bridge body, making the bridge body in an arc structure. A first sliding portion extending obliquely relative to the clamping gap is provided on the sliding arm. A second sliding portion is connected to the end of the outer-ear headphone component facing the sliding arm, so that the second sliding portion is slidably connected to the first sliding portion. Thus, as the second sliding portion slides relative to the first sliding portion, the outer-ear headphone component moves along the extension direction of the first sliding portion, so that the outer-ear headphone component approaches or moves away from the inner-ear headphone component. In this way, the relative position between the outer-ear headphone component and the inner-ear headphone component can be changed, and thus the size of the clamping gap between the outer-ear headphone component and the inner-ear headphone component can be adjusted. Moreover, the sliding arm and the arc-shaped bridge body cooperate to form the entire bridge. The first sliding portion extending obliquely is provided on the sliding arm, and the end of the outer-ear headphone component facing the sliding arm can approach or move away from one end of the bridge body, so that the expansion and contraction range of the distance between the headphone bridges can be increased, more activity space can be obtained, and its compatibility with different auricle sizes and shapes is better, enabling the headphones to better adapt to the user's ears. The user can adjust the clamping gap according to their own needs, thereby improving the wearing comfort. At the same time, the applicable range of the headphones can be increased, providing a better user experience for consumers. And its structure is simple, with good reliability and low manufacturing cost. Secondly, through the setting of the damping member, the sliding block can be kept stable after moving to any position, and a suitable sliding feel can be provided for the movement of the sliding block, allowing the user to adjust the clamping gap of the headphones with one hand operation. And, through the setting of the baffle, it can block the slot on the sliding arm through the baffle, achieving a dust-proof effect and ensuring that the internal wires are not exposed, meeting the aesthetic requirements. Also, by providing a first clamping portion on the sliding arm and a second clamping portion on the connecting member, the first clamping portion and the second clamping portion are clamped together to realize a clamping and detachable connection structure between the connecting member and the sliding arm, so that the bridge body and the sliding arm can be detachably connected through this connecting member, facilitating the disassembly and assembly between the sliding arm and the bridge body.
