[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] See also Figures 1 to 10 A clip-on earphone with a rotatable and adjustable angle comprises an earphone body 1, wherein the earphone body 1 comprises a first clamping portion 2 connected to the outside of the ear canal, a connecting arm 3 connected to the first clamping portion 2, a rotating structure 4 connected to the connecting arm 3, and a second clamping portion 5 connected to the rotating structure 4, a sound outlet 51 is provided on one side of the second clamping portion 5, the rotating structure 4 and the second clamping portion 5 are rotated relative to the first clamping portion 2 so that the sound outlet 51 of the second clamping portion 5 is aligned with the external ear canal opening, and an insertion end 53 and a dial end 54 connected to the insertion end 53 are provided on one side of the second clamping portion 5. The first clamping part 2 and the second clamping part 5 are two clamping parts used to fix the earphone on the auricle. When the user wears the earphone, the first clamping part 2 and the second clamping part 5 are respectively connected to the outer side and the inner side of the auricle, and the connecting arm 3 is a component used to connect the first clamping part 2 and the second clamping part 5. Furthermore, the design of the rotating structure 4 can allow the second clamping part 5 to rotate within a certain range. By arranging the rotating structure 4 between the connecting arm 3 and the second clamping part 5, the rotating structure 4 and the second clamping part 5 are rotated relative to the first clamping part 2 so that the sound outlet 51 of the second clamping part 5 is aligned with the external auditory canal opening, ensuring that the earphone can efficiently transmit music into the ear canal, reducing transmission losses, and improving the wearing comfort of the user, effectively The user experience is improved, and the problem that the sound outlet of the existing clip-on earphones cannot be effectively aligned with the user's external auditory canal, resulting in the user being unable to truly hear the sound output from the earphone sound outlet and wearing discomfort, which reduces the user experience, is solved. Furthermore, the second clamping portion 5 is an irregular circle, and the second clamping portion 5 is provided with a relatively narrow insertion end 53 on one side of the sound outlet 51. Such a design can facilitate the user to insert the second clamping portion 5 into the auricle, effectively improving the wearing convenience of the earphone, and the second clamping portion 5 is provided with a dial end 54 with a circular cross-sectional arc on both sides in the vertical direction. The design of the dial end 54 can facilitate the user to dial the second clamping portion 5 when it needs to adjust it, effectively improving the user experience.

[0028] Furthermore, the rotating structure 4 includes a rotating member 41 connected to the connecting arm 3, the rotating member 41 includes a fixing portion 411 connected to the connecting arm 3 and a rotating shaft 412 connected to the fixing portion 411, the connecting arm 3 is provided with a first connecting hole 31 for connecting to the fixing portion 411, the fixing portion 411 matches the first connecting hole 31, the fixing portion 411 is cooperatively connected with the first connecting hole 31 so that the connecting arm 3 is fixedly connected to the rotating member 41, and the circuit elements and the speaker elements of the earphone are electrically connected through wires passing through the inside of the connecting arm 3. The fixing portion 411 matches the first connecting hole 31 of the connecting arm 3, and the fixing portion 411 is connected with the first connecting hole 31 through the matching connection, so that the connecting arm 3 and the rotating member 41 are fixedly connected. Such a design can ensure that the rotating member 41 is firmly fixed on the connecting arm 3, thereby effectively improving the stability and reliability of the connection. At the same time, the rotating shaft 412 is connected to the fixing portion 411, so that the second clamping portion 5 can be allowed to rotate around the rotating shaft 412, so that the sound outlet 51 is aligned with the external auditory canal opening, thereby effectively improving the practicality of the earphone. In addition, the wire passes through the inside of the connecting arm 3, thereby realizing the electrical connection between the circuit element and the speaker element, and at the same time effectively ensuring that the wire will not be broken or damaged due to rotation, thereby effectively improving the structural stability and reliability of the earphone.

[0029] Furthermore, the second clamping portion 5 includes a shell 52 connected to the rotating shaft 412, and the shell 52 is provided with a second connecting hole 521 for the rotating shaft 412 to pass through. The rotating structure 4 also includes a damping member 42, a washer 43 and a retaining spring 44 which are sequentially sleeved on the outside of the rotating shaft 412, and the rotating shaft 412 is provided with a first fixing groove 4121 which is matched and connected with the retaining spring 44, and the retaining spring 44 is clamped in the first fixing groove 4121, and the two sides of the damping member 42 are respectively abutted against the shell 52 and the washer 43. The housing 52 is provided with a second connecting hole 521 for connecting with the rotating shaft 412 to realize the rotation function of the second clamping portion 5. Further, the rotating structure 4 also includes a damping member 42, a washer 43 and a retaining spring 44 which are sequentially sleeved on the outside of the rotating shaft 412. The inner diameters of the damping member 42, the washer 43 and the retaining spring 44 are matched with the rotating shaft 412. The outer diameter of the retaining spring 44 is less than or equal to the outer diameter of the washer 43, ensuring that the retaining spring 44 can prevent the rotating structure 4 from escaping from the second clamping portion 5. Similarly, the outer diameter of the washer 43 is greater than or equal to the outer diameter of the washer 43. The outer diameter of the damping member 42 is designed in this way to ensure that the washer 43 can effectively abut against the damping member 42, so that the damping member 42 and the washer 43 can stably produce a damping effect. Further, the clamping spring 44 is provided with a connecting port 441 for the rotation shaft 412 to pass through, and the width of the connecting port 441 is smaller than the inner diameter of the first fixing groove 4121. Since the clamping spring 44 has a certain elasticity, the clamping spring 44 is clamped in the first fixing groove 4121 of the rotation shaft 412. The clamping spring 44 is also provided with a first extending portion 442. The connecting port 441 is located between the two first extending portions. The first extension portion 442 is provided with a retaining spring hole 443. The retaining spring 44 is generally made of spring steel. When the retaining spring 44 is clamped in the first fixing groove 4121, a special tool, namely, retaining spring pliers, is required. When installing the retaining spring 44, the two pliers tips of the retaining spring pliers are respectively inserted into the two retaining spring holes 443, and are pinched at one end of the handle to make the connecting port 441 open to a diameter larger than the shaft diameter of the rotating shaft 412 and installed in the first fixing groove 4121. After the handle of the retaining spring pliers is loosened, the connecting port 441 is restored to a state smaller than the shaft diameter of the rotating shaft 412, so as to achieve The fixing of the retaining spring 44 and the first fixing groove 4121 prevents the retaining spring 44 from loosening from the rotating shaft 412. Such a design can ensure the stable connection between the rotating structure 4 and the second clamping part 5, prevent the rotating structure 4 from escaping from the second clamping part 5, and effectively improve the connection stability and reliability of the earphone. Furthermore, the first extension part 442 and the retaining spring hole 443 extend from the outside of the gasket 43. Such a design can facilitate the installation and removal of the retaining spring 44. If the retaining spring 44 is C-shaped, when the rotating structure 4 and the second clamping part 5 are assembled,The retaining spring 44 and the washer 43 will overlap each other, which makes it inconvenient to remove the retaining spring 44, greatly increasing the difficulty of disassembly and maintenance of the earphone. Therefore, the design of the first extension portion 442 and the retaining spring hole 443 can effectively reduce the difficulty of installation and removal of the earphone, and effectively improve the production efficiency of the earphone. Furthermore, the damping member 42 provides a damping feeling when the second clamping portion 5 rotates, preventing the earphone from suddenly changing its angle due to accidental collision, and plays a role in fixing the rotation angle of the second clamping portion 5. The design of the washer 43 provides a stable friction coefficient for the damping member 42, which can ensure that the damping effect generated by the damping member 42 remains stable, effectively improving the stability and reliability of the rotating structure 4, and at the same time can prevent the retaining spring 44 from directly contacting the damping member 42, resulting in wear of the damping member 42. The problem is solved, and the service life of the damping member 42 is effectively improved. In addition, if the rotating structure 4 lacks the retaining spring 44 and the first fixing groove 4121, when the external world applies an outward pulling force to the rotating member 41, it will not be able to effectively prevent the rotating structure 4 from escaping from the second clamping portion 5. Therefore, the matching connection between the retaining spring 44 and the first fixing groove 4121 is the key to the relative position fixation of the rotating structure 4 and the second clamping portion 5. If the rotating structure 4 lacks the washer 43, the retaining spring 44 will directly contact the damping member 42, so that the damping member 42 will wear, resulting in a reduction in the service life of the earphone. Similarly, if the rotating structure 4 lacks the damping member 42, it will not be possible to fix the rotation angle of the second clamping portion 5, thereby reducing the practicality of the earphone.

[0030] Furthermore, a boss 522 abutting against the gasket 43 is provided on the inner side of the shell 52 to limit the relative position of the rotating structure 4 and the shell 52, and the boss 522 encloses a second fixing groove 523 for accommodating the damping member 42. The boss 522 is designed to abut against the gasket 43, thereby limiting the relative position between the rotating structure 4 and the shell 52, preventing the rotating structure 4 from escaping from the shell 52 during use of the earphone, and effectively improving the structural stability and reliability of the earphone. Furthermore, the second fixing groove 523 enclosed by the boss 522 is used to accommodate the damping member 42 to ensure that the damping member 42 can be stably installed in the second fixing groove 523, effectively preventing the second clamping portion 5 from deforming or shifting during the rotation process, resulting in the problem that the damping member 42 cannot effectively provide a damping effect, and at the same time effectively improving the structural compactness of the earphone.

[0031] Furthermore, a limiting groove 524 is provided on the outer side of the shell 52, and the limiting groove 524 is connected to the first connecting hole 31. A limiting portion 4122 is provided on the side of the rotating shaft 412 and extends into the limiting groove 524 for limiting the rotation angle of the second clamping portion 5. The number of the limiting grooves 524 is the same as the number of the limiting portions 4122. The limiting groove 524 is arranged on the outer side of the shell 52 and is connected to the first connecting hole 31, and is used to cooperate with the limiting portion 4122 on the rotating shaft 412 to limit the rotation angle of the second clamping portion 5. Such a design can accurately control the rotation angle of the second clamping portion 5, ensure that the user can adjust the position of the sound outlet 51 within a specific range, and prevent the excessive rotation of the second clamping portion 5 from causing damage to the internal electrical components of the earphone. In addition, when the rotating member 41 extends into the shell 52, the limiting groove 524 and the limiting portion 4122 can limit the extension length of the rotating member 41, play a role in positioning the connection between the rotating member 41 and the shell 52, and effectively improve the connection accuracy and uniformity of the rotating member 41 and the shell 52. Furthermore, the number of the limiting grooves 524 is the same as the number of the limiting portions 4122, which means that each of the limiting portions 4122 cooperates with a corresponding limiting groove 524. Such a design can effectively improve the structural stability and reliability of the earphone.

[0032] Furthermore, the number of the limiting grooves 524 is two, and the two limiting grooves 524 are symmetrically arranged, and the rotatable angle range of the second clamping part 5 is 30-75 degrees. The number of the limiting grooves 524 is two, which means that the number of the limiting parts 4122 is also two. The matching connection between the limiting grooves 524 and the limiting parts 4122 determines the rotatable angle of the second clamping part 5. When the second clamping part 5 reaches the rotatable limit in the clockwise direction, one end of the side surface of the limiting part 4122 abuts against one end of the side surface of the limiting groove 524. When the second clamping part 5 reaches the rotatable limit in the counterclockwise direction, the other end of the side surface of the limiting part abuts against the other end of the side surface of the limiting groove 524. The two ends are abutted against each other, and further, the two limit grooves 524 are symmetrically arranged. The symmetrical layout can effectively ensure that the second clamping part 5 can rotate at the same angle in the clockwise direction and the counterclockwise direction. At the same time, the setting of the two limit grooves 524 can provide two rotation stop points for the earphone, thereby preventing the failure to limit the rotation angle of the second clamping part 5 due to damage of the limit groove 524 when a single limit groove 524 is set. Therefore, the setting of the two limit grooves 524 and the limit part 4122 can effectively improve the structural strength of the earphone.

[0033] Furthermore, an elastic member 32 made of elastic deformable material is provided inside the connecting arm 3 , the connecting arm 3 is U-shaped, the projection of the second clamping portion 5 is elliptical, and the axis of the rotating shaft 412 is eccentrically arranged with respect to the center line of the second clamping portion 5 . The connecting arm 3 is designed to be U-shaped, and an elastic member 32 made of elastically deformable material is provided inside the connecting arm 3, which means that when wearing the earphone, the user can apply opposite pulling forces to the first clamping part 2 and the second clamping part 5 to cause the connecting arm 3 to undergo elastic deformation, thereby expanding the distance between the first clamping part 2 and the second clamping part 5, and clamping the external auricle between the first clamping part 2 and the second clamping part 5. After wearing, the connecting arm 3 returns to its original shape, so that the distance between the first clamping part 2 and the second clamping part 5 returns to its original size, thereby fixing the earphone on the auricle. Furthermore, the projection of the second clamping part 5 is designed to be elliptical, which can adapt to the ear shapes of different users, improve the fit and comfort between the second clamping part 5 and the ear, avoid discomfort to the user when wearing, effectively improve the user's usage experience, and further improve the earphone. In one step, the axis of the rotating shaft 412 is eccentrically arranged with respect to the center line of the second clamping part 5. When the second clamping part 5 rotates around the axis of the rotating shaft 412, specifically, since the connecting arm 3 is provided with an elastic member 32 made of elastic deformable material, it means that the connecting arm 3 needs to be made of a material that can undergo elastic deformation, and the rotating part 41 needs to be made of a material with higher strength. The connecting arm 3 can be produced by a double-shot molding process. By placing the elastic member 32 in the mold in advance, an injection molding machine is used to inject the hard material for making the rotating part 41 into the mold to form the rotating part 41, and then a second injection molding is performed to inject the soft material for making the connecting arm 3 into the mold. While forming the connecting arm 3, the connecting arm 3 and the rotating part 41 are fixedly connected, which reduces the need for subsequent assembly and effectively improves production efficiency.

[0034] Furthermore, the damping member 42 is made of elastic material, the cross-sectional diameter of the damping member 42 is greater than the depth of the second fixing groove 523, and the outer diameter of the damping member 42 is greater than or equal to the diameter of the second fixing groove 523. The elastic material used as the manufacturing material of the damping member 42 may be silicone, rubber, polyurethane, etc., but is not limited to the above materials. Furthermore, by designing the cross-sectional diameter of the damping member 42 to be greater than the depth of the second fixing groove 523, it means that when the damping member 42 is installed alone in the second fixing groove 523, the damping member 42 will protrude from the second fixing groove 523, but when the damping member 42 is assembled with other components of the rotating structure 4, the washers 43 and 44 located on both sides of the damping member 42 respectively The second fixing groove 523 will squeeze the damping member 42 so that the damping member 42 generates a stable damping force when the second clamping portion 5 rotates, and fixes the rotation angle of the second clamping portion 5. Furthermore, the outer diameter of the damping member 42 is greater than or equal to the diameter of the second fixing groove 523. Such a design can effectively prevent the damping member 42 from shifting in the second fixing groove 523, thereby ensuring that the damping member 42 can stably provide damping force for the rotation of the second clamping portion 5, thereby effectively improving the practicality and reliability of the earphones.

[0035] Furthermore, the outer diameter of the washer 43 is larger than the diameter of the second fixing groove 523. The outer diameter of the washer 43 is larger than the diameter of the second fixing groove 523, which means that when an outward pulling force is applied to the rotating member 41, the washer 43 can abut against the boss 522, preventing the washer 43 from applying excessive pressure to the elastic member 32 due to the pulling force, thereby causing damage to the elastic member 32. At the same time, combined with the matching connection between the clamping spring 44 and the first fixing groove 4121, the rotating structure 4 can be prevented from escaping from the second clamping portion 5, effectively improving the structural stability and reliability of the earphone.

[0036] A method for adjusting an ear-clip earphone capable of rotating and adjusting an angle, comprising the following steps: S1. Clamp the earphones onto the auricle of the human body, wherein the first clamping portion 2 and the second clamping portion 5 are respectively located on the outside and inside of the auricle of the human body; in step S1, the user needs to correctly clamp the earphones onto the auricle of the human body, and when the user finishes wearing the earphones, the first clamping portion 2 should be located on the outside of the auricle.

[0037] S2. Rotate the second clamping part 5. The second clamping part 5 rotates a certain angle around the axis of the rotating shaft 412 so that the sound outlet 51 is aligned with the external auditory canal opening. In step S2, the user can rotate the second clamping part 5 so that it rotates a certain angle around the axis of the rotating shaft 412. By rotating the second clamping part 5, the sound outlet 51 on the second clamping part 5 is aligned with the external auditory canal opening, thereby ensuring that the sound can enter the user's ear at the best angle, improving the sound quality and sound effect. At the same time, by rotating the second clamping part 5, the second clamping part 5 is more adapted to the user's auricle, effectively improving the wearing comfort of the earphone. Furthermore, in order to ensure the stability of the earphone during wearing, the outer side of the rotating shaft 412 is sequentially sleeved with a damping member 42, a gasket 43 and a retaining spring 44. The design of the damping member 42 can provide a damping force for the rotation of the second clamping part 5, so as to fix the second clamping part 5 at any rotation angle. Secondly, in order to ensure the stability of the earphone during wearing, the damping member 42 is sequentially sleeved with a gasket 43 and a retaining spring 44. The damping member 42 is designed to provide a damping force for the rotation of the second clamping part 5, so as to fix the second clamping part 5 at any rotation angle. The damping member 42 is in a relative position to the rotating shaft 412, and the rotating shaft 412 will not fall out of the second clamping portion 5. The rotating shaft 412 is provided with a first fixing groove 4121 which cooperates with the retaining spring 44. The retaining spring 44 is clamped in the first fixing groove 4121 to prevent the damping member 42 from falling out of the rotating shaft 412 and the rotating shaft 412 from falling out of the second clamping portion 5, thereby effectively improving the structural stability and reliability of the earphone. In addition, in order to prevent the retaining spring 44 from directly contacting and rubbing with the damping member 42, thereby causing wear of the damping member 42, the washer 43 is arranged between the retaining spring 44 and the damping member 42, so that the damping member 42 can provide a stable damping force for the rotation of the second clamping portion 5, thereby extending the service life of the earphone and effectively improving the practicality of the earphone.

[0038] Furthermore, before the method for adjusting the angle of the earphone, there is also an assembly method for the earphone, which includes the following steps: S101, the rotating part 41 and the connecting arm 3 are connected by double-injection molding; such a connection method can realize a fixed connection between the rotating part 41 and the connecting arm 3 during the production process, while meeting the requirement of using different materials for the two, reducing the need for subsequent assembly, and effectively improving production efficiency.

[0039] S102, the rotating shaft 41 passes through the first connecting hole 521 located on the rear shell 526, the damping member 42 and the gasket 43 are sequentially sleeved on the outer side of the rotating shaft 41, and the retaining spring 44 is clamped in the first fixing groove 4121 to connect the front shell 525 and the rear shell 526; adopting such an assembly method, the modular installation of the rotating structure 4 can be realized, which effectively avoids the situation where the subsequent installation needs to repeat the previous installation steps, effectively improves the production efficiency, and facilitates the disassembly and maintenance of the earphones.

[0040] S103, passing the wires for electrically connecting the circuit elements and the speaker elements of the earphone through the wire holes preset inside the connecting arm 3 and the rotating member 4; in this step, passing the wires through the wire holes preset inside the connecting arm 3 and the rotating member 4 in advance can facilitate the subsequent electrical connection of the electrical elements, effectively improving the production efficiency of the earphone.

[0041] S104, assemble the speaker element and the circuit element to the front shell 525 and the first clamping part 2 respectively; adopting such assembly steps can effectively reduce the risk of disconnection between the electrical elements and the wires. If the speaker element and the wires are welded first, the solder joints may easily become loose when the speaker element is subsequently assembled to the front shell 525.
