Technical Field

[0001] This utility model relates to the field of headphones, specifically a clip-on headphone with an adjustable angle. Background Technology

[0002] With the development of technology, headphones have evolved from initial communication tools to modern personal entertainment devices, becoming an indispensable part of people's lives. With the continuous emergence of new materials and technologies, headphones will continue to develop in the future towards greater intelligence, portability, and personalization. Nowadays, there are many types of headphones on the market, including in-ear, over-ear, ear hook, headband, and clip-on headphones, etc.

[0003] Currently, most clip-on headphones on the market have a fixed, one-piece structure with a fixed sound output. Since everyone's ear canal shape and size are different, fixed-piece clip-on headphones cannot perfectly match everyone's ear canal. Therefore, the headphone's sound outlet cannot be effectively aligned with the user's ear canal opening, resulting in inefficient music transmission and significant transmission loss. Users cannot truly hear the sound output from the headphone's outlet, thus reducing the user experience. Therefore, there is a need to develop a clip-on headphone with an adjustable angle to solve the problem of the existing clip-on headphones' sound outlet not being effectively aligned with the user's ear canal, causing users to not be able to truly hear the sound output and experiencing discomfort, thus reducing the user experience. Utility Model Content

[0004] To address the aforementioned problem that existing clip-on headphones cannot effectively align their sound outlet with the user's ear canal, resulting in the user not being able to hear the sound output from the headphone outlet and thus reducing the user experience, the technical solution adopted by this utility model to solve this problem is:

[0005] A rotatable and adjustable clip-on earphone includes an earphone body. The earphone body includes a first clamping part connected to the outside of the ear canal, a connecting arm connected to the first clamping part, a rotating structure connected to the connecting arm, and a second clamping part connected to the rotating structure. A sound outlet is provided on one side of the second clamping part. The rotating structure and the second clamping part rotate relative to the first clamping part so that the sound outlet of the second clamping part is aligned with the opening of the external ear canal.

[0006] Furthermore, the rotating structure includes a rotating component connected to the connecting arm. The rotating component includes a fixed part connected to the connecting arm and a rotating shaft connected to the fixed part. The connecting arm is provided with a first connecting hole for connecting to the fixed part. The fixed part matches the first connecting hole. The fixed part and the first connecting hole are engaged to fix the connecting arm to the rotating component. The circuit elements and speaker elements of the earphone are electrically connected through wires passing through the inside of the connecting arm.

[0007] Furthermore, the second clamping part includes a housing connected to the rotating shaft. The housing has a second connecting hole through which the rotating shaft passes. The rotating structure also includes a damping member, a washer, and a retaining ring sequentially sleeved on the outside of the rotating shaft. The rotating shaft has a first fixing groove that cooperates with the retaining ring. The retaining ring is engaged in the first fixing groove. The two sides of the damping member abut against the housing and the washer, respectively.

[0008] Furthermore, the inner side of the housing is provided with a boss that abuts against the washer to limit the relative position of the rotating structure and the housing, and the boss surrounds to form a second fixing groove for accommodating the damping element.

[0009] Furthermore, the outer side of the housing is provided with a limiting groove, which communicates with the first connecting hole. The side of the rotating shaft is provided with a limiting part that extends into the limiting groove to limit the rotation angle of the second clamping part. The number of limiting grooves is the same as the number of limiting parts.

[0010] Furthermore, there are two limiting grooves, which are symmetrically arranged, and the rotation angle range of the second clamping part is 30-75 degrees.

[0011] Furthermore, the connecting arm is provided with an elastic element made of elastic deformable material, the connecting arm is U-shaped, the projection of the second clamping part is elliptical, and the axis of the rotating shaft is eccentrically set with respect to the center line of the second clamping part.

[0012] Furthermore, the damping element is made of an elastic material, the cross-sectional diameter of the damping element is greater than the depth of the second fixing groove, and the outer diameter of the damping element is greater than or equal to the diameter of the second fixing groove.

[0013] Furthermore, the outer diameter of the washer is larger than the diameter of the second fixing groove.

[0014] Furthermore, the distance between the first clamping part and the second clamping part is greater than or equal to the thickness of the clamped human auricle, and less than the maximum distance between the inner and outer surfaces of the clamped human auricle.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention features a rotating structure between the connecting arm and the second clamping part. The rotating structure and the second clamping part rotate relative to the first clamping part, aligning the sound outlet of the second clamping part with the user's ear canal.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Please see Figures 1 to 10 A rotatable and adjustable clip-on earphone includes an earphone body 1. The earphone body 1 includes a first clamping part 2 connected to the outside of the ear canal, a connecting arm 3 connected to the first clamping part 2, a rotating structure 4 connected to the connecting arm 3, and a second clamping part 5 connected to the rotating structure 4. The second clamping part 5 has a sound outlet 51 on one side. The rotating structure 4 and the second clamping part 5 rotate relative to the first clamping part 2 so that the sound outlet 51 of the second clamping part 5 is aligned with the opening of the external ear canal. The second clamping part 5 has an insertion end 53 on one side and a toggle end 54 connected to the insertion end 53. 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 connected to the outer and inner sides of the auricle, respectively. 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 allows the second clamping part 5 to rotate within a certain range. By setting 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 rotate relative to the first clamping part 2 so that the sound outlet 51 of the second clamping part 5 is aligned with the external ear canal opening. This ensures that the earphone can efficiently transmit music into the ear canal, reduce transmission loss, improve user wearing comfort, and effectively improve the user experience. It solves the problem that the sound outlet of existing ear-clamping earphones cannot be effectively aligned with the user's external ear canal, resulting in the user not being able to truly hear the sound output from the earphone outlet and experiencing wearing discomfort, which reduces the user experience.

[0029] Furthermore, the rotating structure 4 includes a rotating member 41 connected to the connecting arm 3. The rotating member 41 includes a fixing part 411 connected to the connecting arm 3 and a rotating shaft 412 connected to the fixing part 411. The connecting arm 3 is provided with a first connecting hole 31 for connecting to the fixing part 411. The fixing part 411 matches the first connecting hole 31. The fixing part 411 and the first connecting hole 31 are connected to each other so that the connecting arm 3 is fixedly connected to the rotating member 41. The circuit elements and speaker elements of the earphone are electrically connected through wires passing through the inside of the connecting arm 3. The fixing part 411 matches the first connecting hole 31 of the connecting arm 3. Through the cooperation between the fixing part 411 and the first connecting hole 31, the connecting arm 3 and the rotating part 41 are fixedly connected. This design ensures that the rotating part 41 is firmly fixed on the connecting arm 3, effectively improving the stability and reliability of the connection. At the same time, the rotating shaft 412 is connected to the fixing part 411, allowing the second clamping part 5 to rotate around the rotating shaft 412, thereby aligning the sound outlet 51 with the ear canal opening, effectively improving the practicality of the headphones. In addition, the wire passes through the inside of the connecting arm 3, realizing the electrical connection between the circuit components and the speaker components, while effectively ensuring that the wire will not break or be damaged due to rotation, effectively improving the structural stability and reliability of the headphones.

[0030] Furthermore, the second clamping part 5 includes a housing 52 connected to the rotating shaft 412. The housing 52 is provided with a second connecting hole 521 through which the rotating shaft 412 passes. The rotating structure 4 also includes a damping member 42, a washer 43 and a retaining ring 44 sequentially sleeved on the outside of the rotating shaft 412. The rotating shaft 412 is provided with a first fixing groove 4121 that cooperates with the retaining ring 44. The retaining ring 44 is locked in the first fixing groove 4121. The two sides of the damping member 42 abut against the housing 52 and the washer 43 respectively. The outer casing 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 part 5. Further, the rotating structure 4 also includes a damping element 42, a washer 43, and a retaining ring 44 sequentially sleeved on the outside of the rotating shaft 412. The inner diameters of the damping element 42, washer 43, and retaining ring 44 are all matched with the rotating shaft 412. The outer diameter of the retaining ring 44 is less than or equal to the outer diameter of the washer 43, ensuring that the retaining ring 44 can prevent the rotating structure 4 from dislodging from the second clamping part 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 element 42 is designed to ensure that the washer 43 can effectively abut against the damping element 42, so that the damping element 42 and the washer 43 can stably generate a damping effect. Furthermore, the retaining spring 44 has a connection port 441 through which the rotating shaft 412 passes. The width of the connection port 441 is smaller than the inner diameter of the first fixing groove 4121. Because the retaining spring 44 has a certain elasticity, it is engaged in the first fixing groove 4121 of the rotating shaft 412. The retaining spring 44 also has a first extension 442, and the connection port 441 is located between the two first extensions. Between the extensions 442, and with a retaining ring hole 443 on the first extension 442, the retaining ring 44 is generally made of spring steel. When the retaining ring 44 is engaged in the first fixing groove 4121, a special tool, namely retaining ring pliers, is required. When installing the retaining ring 44, the two tips of the retaining ring pliers are inserted into the two retaining ring holes 443 respectively, and the handle is squeezed together to open the connection port 441 to a size larger than the shaft diameter of the rotating shaft 412, allowing it to be installed in the first fixing groove 4121. After releasing the handle of the retaining ring pliers, the connection port 441 returns to a state smaller than the shaft diameter of the rotating shaft 412, thus achieving... The retaining spring 44 is fixed to the first fixing groove 4121, preventing the retaining spring 44 from loosening from the rotating shaft 412. This design ensures a stable connection between the rotating structure 4 and the second clamping part 5, preventing the rotating structure 4 from coming out of the second clamping part 5, effectively improving 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 washer 43. This design facilitates 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 snap ring 44 and the washer 43 overlap, making it difficult to disassemble the snap ring 44 and greatly increasing the difficulty of disassembling and repairing the headphones. Therefore, the design of the first extension 442 and the snap ring hole 443 can effectively reduce the difficulty of installing and disassembling the headphones and effectively improve the production efficiency of the headphones. Furthermore, the damping element 42 provides damping sensation when the second clamping part 5 rotates, preventing the headphones from suddenly changing angle due to accidental collisions, and plays a role in fixing the rotation angle of the second clamping part 5. The design of the washer 43 provides a stable coefficient of friction for the damping element 42, which can ensure that the damping effect produced by the damping element 42 remains stable, effectively improving the stability and reliability of the rotating structure 4. At the same time, it can also prevent the snap ring 44 from directly contacting the damping element 42, thus preventing wear of the damping element 42. This effectively improves the service life of the damping element 42. Furthermore, if the rotating structure 4 lacks the retaining ring 44 and the first fixing groove 4121, it will be unable to effectively prevent the rotating structure 4 from detaching from the second clamping part 5 when an outward pulling force is applied to the rotating element 41. Therefore, the cooperative connection of the retaining ring 44 and the first fixing groove 4121 is crucial for fixing the relative position of the rotating structure 4 and the second clamping part 5. If the rotating structure 4 lacks the washer 43, the retaining ring 44 will directly contact the damping element 42, causing wear on the damping element 42 and reducing the service life of the headphones. Similarly, if the rotating structure 4 lacks the damping element 42, it will be impossible to fix the rotation angle of the second clamping part 5, thus reducing the practicality of the headphones.

[0031] Furthermore, the inner side of the outer shell 52 is provided with a boss 522 that abuts against the washer 43 to limit the relative position between the rotating structure 4 and the outer shell 52. The boss 522 encloses and forms a second fixing groove 523 for accommodating the damping member 42. The boss 522 is designed to abut against the washer 43, thereby limiting the relative position between the rotating structure 4 and the outer shell 52, preventing the rotating structure 4 from detaching from the outer shell 52 during use of the headphones, effectively improving the structural stability and reliability of the headphones. Furthermore, the second fixing groove 523 formed by the boss 522 is used to accommodate the damping member 42, ensuring that the damping member 42 can be stably installed in the second fixing groove 523, effectively preventing the second clamping part 5 from deforming or shifting during rotation, which would cause the damping member 42 to fail to provide effective damping, while also effectively improving the structural compactness of the headphones.

[0032] Furthermore, the outer side of the outer shell 52 is provided with a limiting groove 524, which communicates with the first connecting hole 31. The side of the rotating shaft 412 is provided with a limiting part 4122 that extends into the limiting groove 524 to limit the rotation angle of the second clamping part 5. The number of limiting grooves 524 is the same as the number of limiting parts 4122. The limiting groove 524 is located on the outer side of the housing 52 and communicates with the first connecting hole 31. It is used to cooperate with the limiting part 4122 on the rotating shaft 412 to limit the rotation angle of the second clamping part 5. This design can precisely control the rotation angle of the second clamping part 5, ensuring that the user can adjust the position of the sound outlet 51 within a specific range and preventing excessive rotation of the second clamping part 5 from damaging the internal electrical components of the headphones. In addition, when the rotating part 41 extends into the housing 52, the limiting groove 524 and the limiting part 4122 can limit the extension length of the rotating part 41, which plays a role in positioning the connection between the rotating part 41 and the housing 52, effectively improving the accuracy and uniformity of the connection between the rotating part 41 and the housing 52. Furthermore, the number of limiting grooves 524 is the same as the number of limiting parts 4122, which means that each limiting part 4122 cooperates with a corresponding limiting groove 524. This design can effectively improve the structural stability and reliability of the headphones.

[0033] Furthermore, there are two limiting grooves 524, which are symmetrically arranged. The rotational angle range of the second clamping part 5 is 30-75 degrees. The two limiting grooves 524 mean that there are also two limiting parts 4122. The cooperation between the limiting grooves 524 and the limiting parts 4122 determines the rotational angle of the second clamping part 5. When the second clamping part 5 reaches its clockwise rotational limit, one end of the side of the limiting part 4122 abuts against one end of the side of the limiting groove 524. When the second clamping part 5 reaches its counterclockwise rotational limit, the other end of the side of the limiting part abuts against the other end of the side of the limiting groove 524. The ends abut against each other. Furthermore, the two limiting grooves 524 are symmetrically arranged. The symmetrical layout can effectively ensure that the second clamping part 5 has the same rotational angle in the clockwise and counterclockwise directions. At the same time, the setting of the two limiting grooves 524 can provide two rotation stop points for the earphone, preventing the second clamping part 5 from being unable to be restricted due to damage to the limiting groove 524 when a single limiting groove 524 is set. Therefore, the setting of the two limiting grooves 524 and the limiting part 4122 can effectively improve the structural strength of the earphone.

[0034] Furthermore, the connecting arm 3 is internally provided with an elastic element 32 made of a deformable elastic material. The connecting arm 3 is U-shaped, the projection of the second clamping part 5 is elliptical, and the axis of the rotating shaft 412 is eccentrically positioned with respect to the center line of the second clamping part 5. Designing the connecting arm 3 as U-shaped, and providing the elastic element 32 made of a deformable elastic material within it, means that when the user wears the headphones, they can apply opposite pulling forces to the first clamping part 2 and the second clamping part 5, causing the connecting arm 3 to elastically deform. This expands the distance between the first clamping part 2 and the second clamping part 5, allowing the outer ear to be inserted between them. After wearing the headphones, the connecting arm 3 returns to its original shape, restoring the original distance between the first clamping part 2 and the second clamping part 5. The size is adjusted to secure the earphone to the ear. Furthermore, the projection of the second clamping part 5 is designed as an ellipse to adapt to different ear shapes, improving the fit and comfort of the second clamping part 5 and preventing discomfort during wear, thus effectively enhancing the user experience. Additionally, the second clamping part 5 is an irregular circle, and it has a relatively narrow insertion end 53 on the side of the sound outlet 51. This design makes it easy for the user to insert the second clamping part 5 into the ear, effectively improving the ease of wearing the earphone. For ease of use, the second clamping part 5 has two actuating ends 54 with rounded cross-sections on both sides in the vertical direction. The design of the actuating ends 54 makes it convenient for users to adjust the second clamping part 5, effectively improving the user experience. Furthermore, the axis of the rotating shaft 412 is eccentrically set 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 has an elastic element 32 made of elastic deformable material inside, it means that the connecting arm 3 needs to use a flexible... The material undergoes elastic deformation and is used for manufacturing. The rotating part 41 requires a high-strength material. The connecting arm 3 can be produced using a double-injection molding process. By placing the elastic part 32 into the mold in advance, the hard material for making the rotating part 41 is injected into the mold using an injection molding machine to form the rotating part 41. Then, a second injection molding is performed to inject the soft material for making the connecting arm 3 into the mold, forming the connecting arm 3 and simultaneously achieving a fixed connection between the connecting arm 3 and the rotating part 41. This reduces the need for subsequent assembly and effectively improves production efficiency.

[0035] Furthermore, the damping element 42 is made of an elastic material. The cross-sectional diameter of the damping element 42 is greater than the depth of the second fixing groove 523, and the outer diameter of the damping element 42 is greater than or equal to the diameter of the second fixing groove 523. Using an elastic material as the manufacturing material for the damping element 42, the elastic material can be silicone, rubber, polyurethane, etc., but is not limited to these materials. Furthermore, by designing the cross-sectional diameter of the damping element 42 to be greater than the depth of the second fixing groove 523, it means that when the damping element 42 is installed alone in the second fixing groove 523, the damping element 42 will protrude from the second fixing groove 523. However, when the damping element 42 is assembled with other components of the rotating structure 4, the washers 43 located on both sides of the damping element 42 and... The second fixing groove 523 compresses the damping member 42, so that the damping member 42 generates a stable damping force when the second clamping part 5 rotates, and fixes the rotation angle of the second clamping part 5. Furthermore, the outer diameter of the damping member 42 is greater than or equal to the diameter of the second fixing groove 523. This design can effectively prevent the damping member 42 from shifting in the second fixing groove 523, ensuring that the damping member 42 can stably provide damping force for the rotation of the second clamping part 5, effectively improving the practicality and reliability of the headphones.

[0036] Furthermore, the outer diameter of the washer 43 is larger than the diameter of the second fixing groove 523. This larger outer diameter 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, thus avoiding damage to the elastic member 32. Simultaneously, combined with the engagement of the retaining spring 44 and the first fixing groove 4121, this prevents the rotating structure 4 from dislodging from the second clamping part 5, effectively improving the structural stability and reliability of the earphone.

[0037] Furthermore, the distance between the first clamping part 2 and the second clamping part 5 is greater than or equal to the thickness of the clamped human auricle, and less than the maximum distance between the inner and outer surfaces of the clamped human auricle. Since the human auricle is irregularly curved, the maximum distance between its inner and outer surfaces must be greater than its thickness. By designing the distance between the first clamping part 2 and the second clamping part 5 to be greater than or equal to the thickness of the clamped human auricle, and less than the maximum distance between its inner and outer surfaces, it is ensured that the earphone fits snugly against the user's ear without causing excessive pressure or discomfort, effectively improving the user experience.
