Description

A clip-on earphone Technical Field

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

[0002] With the development of electronic devices, smartphones, tablets, and other electronic products have become widely used in people's daily lives. As an important accessory for these electronic products, wireless headphones are also becoming increasingly popular. Existing headphone styles include in-ear, semi-in-ear, earbud-style, earhook, and clip-on styles, each with its own advantages. Clip-on earphones are mostly open-ear headphones (the earphone body does not extend into the ear canal). Open-ear headphones have the advantages of being gentle on the ears, harming hearing, and being comfortable to wear.

[0003] There are many ways to clamp your ears with clip-on earphones. The most common clip-on earphones on the market primarily use material deformation to prevent them from falling out. However, the constant clamping force generated by material deformation can cause ear pain, especially for people with thick auricles, where the clamping force is greater and the pain is more pronounced.

[0060] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0061] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0062] Example 1

[0063] As shown in Figures 1 to 9, an ear-clip headphone includes a functional part 10, a clamping part 20 and a hinge mechanism 30. The functional part 10 includes a first shell 11; the clamping part 20 includes a second shell 21; the first shell 11 and the second shell 21 are rotatably connected by the hinge mechanism 30, which is used to adjust and fix the angle between the functional part 10 and the clamping part 20 to form a clamping space for clamping the ear.

[0064] Specifically, the earphones of this embodiment are divided into two parts: a functional portion 10 and a clamping portion 20. The functional portion 10 and the clamping portion 20 are connected together by a hinge mechanism 30. The functional portion 10 is used to implement the earphone function. The first housing 11 is provided with various electronic components that implement the earphone function. The first housing 11 is also provided with a speaker hole and a sound receiving hole. The speaker hole is used for broadcasting, and the sound receiving hole is used for receiving sound. The clamping portion 20 is mainly used to clamp the earphones when they are worn. The earphones can have two states: a non-worn state and a worn state. In the non-worn state, as shown in Figure 1, the portion where the first housing 11 and the second housing 21 are connected is flush with the second housing 21, and the second housing 21 is flat. In the worn state, as shown in Figure 2, the second housing 21 rotates toward the first housing 11, and the second housing 21 is not flat. The portion where the first housing 11 and the second housing 21 are connected is not flush with the second housing 21, and a clamping space for clamping the ear is formed between the functional portion 10 and the clamping portion 20. When worn, the functional portion 10 is located in front of the ear and close to the ear canal, and the clamping portion 20 is located behind the ear, forming a clamping space for clamping the ear between the clamping portion 20 and the functional portion 10. Preferably, as shown in Figures 1 and 2, a concave arc-shaped portion 211 is provided on the inner side of the second shell 21. When worn, after the second shell 21 is folded toward the first shell 11, a curved clamping space with a large inner opening and a small outer opening is formed between the arc-shaped portion 211 and the first shell 11 for clamping the auricle. This not only provides a more secure clamping, but also better matches the shape of the ear, making it more comfortable to wear.

[0065] The second shell 21 of the clamping portion 20 and the first shell 11 of the functional portion 10 are rotatably connected via a hinge mechanism 30. The hinge mechanism 30 can change the angle between the second shell 21 and the first shell 11, that is, change the angle between the functional portion 10 and the clamping portion 20, so that the ear-clip headphones can adapt to the ears of different wearers. In addition, the hinge mechanism 30 can also achieve a fixed rotation angle, so that the clamping portion 20 will not continuously exert pressure on the ear during wearing, and the wearing comfort is better.

[0066] In this embodiment, as shown in FIG5 , the functional portion 10 further includes a first bracket 12 fixedly disposed within the first housing 11; the clamping portion 20 further includes a second bracket 22 fixedly disposed within the second housing 21; the second bracket 22 is rotatably connected to the first bracket 12 via a hinge mechanism 30. The first bracket 12 is fixed within the first housing 11 by a sleeve or other method, and the second bracket 22 is fixed within the second housing 21 by a sleeve or other method. Of course, if the process permits, the first bracket 12 can also be integrally formed with the first housing 11, and the second bracket 22 can also be integrally formed with the second housing 21, that is, the first bracket 12 and the first housing 11 are one component, and the second bracket 22 and the second housing 21 are one component.

[0067] In this embodiment, as shown in Figures 3 and 7, the hinge mechanism 30 includes a hinge 31 and a take-up plate 32. The hinge 31 passes through the first bracket 12 and is rotatably connected to the second bracket 22 at both ends. The take-up plate 32 is fixed within the first bracket 12 and wound around the hinge 31. The inner wall of the take-up plate 32 contacts the outer wall of the hinge 31, and the friction between the take-up plate 32 and the hinge 31 forms a rotational damper. After installation, the hinge 31 is disposed within the second housing 21. The second housing 21 can cover the hinge, providing a shield and enhancing the appearance of the earphones. In addition, the second housing 21 can abut against the hinge 31 to prevent it from sliding along its axis.

[0068] The winding piece 32 is fixed in the first bracket 12, and the rotating shaft 31 can rotate in the winding piece 32. The second bracket 22 is fixed together with the rotating shaft 31, and the second bracket 22 can rotate together with the rotating shaft 31. The winding piece 32 can hold the rotating shaft 31 tightly, and the damping of the rotating shaft 31 is achieved by the friction between the winding piece 32 and the rotating shaft 31 to fix the rotation angle of the second shell 21 relative to the first shell 11, so that the second shell 21 is maintained at an angle that clamps the ear, and after wearing, the rotating shaft 31 will not continue to exert pressure on the auricle to solve the comfort problem of wearing the earphones.

[0069] Furthermore, as shown in FIG6 , a stepped hole is provided in the first bracket 12 , which includes a first through hole 121 and a second through hole 122 . The diameter of the first through hole 121 is smaller than that of the second through hole 122 . The take-up plate 32 is disposed in the second through hole 122 , and the rotation shaft 31 passes through the centers of the first through hole 121 and the take-up plate 32 . The take-up plate 32 is installed in the second through hole 122 , and the inner diameter of the take-up plate 32 is equal to or slightly smaller than the diameter of the first through hole 121 , so that the outer wall of the rotation shaft 31 abuts against the inner wall of the take-up plate 32 and forms a rotation damper. The damping force stabilizes the rotation angle of the second bracket 22 , thereby fixing the rotation angle of the clamping portion 20 .

[0070] As shown in FIG6 , the inner sidewall of the first through hole 121 is provided with a raised portion 1211. As shown in FIG7 , the outer sidewall of the rotating shaft 31 is provided with a recessed portion 311. The recessed portion 311 cooperates with the raised portion 1211 to limit the rotation angle of the rotating shaft 31 relative to the first bracket 12. The cooperation between the recessed portion 311 and the raised portion 1211 limits the extreme rotational positions of the first bracket 12 and the clamping portion 20. One of the extreme positions of the clamping portion 20 is a flat position (horizontal state), in which the earphones are not worn. The other extreme position ensures that the earphones clamp firmly to the ears of most people, preventing them from falling off.

[0071] As a variation, in addition to setting a limit on the rotating shaft 31, a limit structure can also be set at a position farther away from the rotating shaft 31. The limit structure can be set between the first shell 11 and the second shell 21. The first shell 11 is provided with a first limit part, and the second shell 21 is provided with a second limit part. The first limit part cooperates with the second limit part to limit the rotation angle of the second shell 21 relative to the first shell 11. The first bracket 12 is nested on the first shell 11, and the second bracket 22 is nested on the second shell 21. The limit structure is set between the first shell 11 and the second shell 21. The nested first bracket 12 and the first shell 11 can be regarded as an integral part, and the nested second bracket 22 and the second shell 21 can also be regarded as an integral part. The transmission chain is short, and the limit position is farther away from the axis, so the limit accuracy is higher and the angular error is smaller. In this embodiment, the above two limit methods can be selected at will, or the two limit methods can be used together.

[0072] Preferably, as shown in Figure 8, the roll 32 includes a fixing portion 321 and a winding portion 322, the first end of the winding portion 322 is connected to the fixing portion 321, the second end of the winding portion 322 is spaced apart from the first end of the winding portion 322 to form an opening 3221, the fixing portion 321 is fixed in the first bracket 12, and the winding portion 322 is wound on the rotating shaft 31; when changing from a non-wearing state to a wearing state, the angle between the clamping portion 20 and the functional portion 10 becomes smaller, the spacing of the openings 3221 becomes larger, and the friction between the roll 32 and the rotating shaft 31 becomes smaller; when changing from a wearing state to a non-wearing state, the angle between the clamping portion 20 and the functional portion 10 becomes larger, the spacing of the openings 3221 becomes smaller, and the friction between the roll 32 and the rotating shaft 31 becomes larger.

[0073] As shown in Figure 4, during the wearing process, that is, when changing from a non-wearing state to a wearing state, the rotating shaft 31 drives the clamping part 20 to rotate counterclockwise. The winding portion 322 of the winding piece 32 tends to open under the friction of the rotating shaft 31, and the opening 3221 on the winding portion 322 becomes larger. The friction between the winding piece 32 and the rotating shaft 31 becomes smaller, the torque of the rotating shaft 32 is small, and the rotation damping of the clamping part 20 becomes smaller, making it easier for the clamping part 20 to rotate to the wearing state. During the process of removing the earphones, that is, when changing from a wearing state to a non-wearing state, the rotating shaft 31 drives the clamping part 20 to rotate clockwise. The opening 3221 on the winding portion 322 becomes smaller, the friction between the rotating shaft 31 and the winding portion 322 of the winding piece 32 becomes larger, and the rotation damping of the clamping part 20 is large.

[0074] The effects that the rotating shaft of this embodiment can achieve are: small damping during wearing, which makes wearing relatively convenient; after wearing, the earphones are stable to wear because the damping when taking them off is relatively large, and they are not likely to fall off.

[0075] To achieve the above-mentioned effect of the rotating shaft, the opening 3221 of the winding portion 322 can be arranged in the following two ways:

[0076] The first type, as shown in Figure 4, the fixing portion 321 is arranged in the first bracket 12 toward the first shell 11, and the opening 3221 is arranged below the fixing portion 321; the second type, as shown in Figure 9, the fixing portion 321 is arranged in the first bracket 12 toward the second shell 21, and the opening 3221 is arranged above the fixing portion 321.

[0077] As shown in Figure 4, in the first configuration, when the shaft 31 rotates counterclockwise, the winding portion 322 is subjected to the friction of the shaft 31, causing the opening 3221 to increase in size and the friction to decrease. Conversely, when removing the earphones, the shaft 31 rotates clockwise, causing the opening 3221 to decrease in size and the friction to increase.

[0078] As shown in Figure 9, in the second configuration, when the shaft 31 rotates counterclockwise, the winding portion 322 is subjected to the friction of the shaft 31, causing the opening 3221 to increase in size and the friction to decrease. Conversely, when removing the earphones, the shaft 31 rotates clockwise, causing the opening 3221 to decrease in size and the friction to increase.

[0079] Example 2

[0080] An earphone with a clip-on design, as shown in Figures 10 to 12, includes a functional portion 10, a clamping portion 20, and a hinge mechanism 30. The functional portion 10 includes a first housing 11; the clamping portion 20 includes a second housing 21. The first housing 11 and the second housing 21 are rotatably connected via the hinge mechanism 30, which is used to adjust and fix the angle between the functional portion 10 and the clamping portion 20 to form a clamping space for clamping the ear. This embodiment differs from the first embodiment in the structure of the hinge mechanism 30. The other structures are the same as those of the first embodiment, and the common parts of this embodiment and the first embodiment are not repeated here.

[0081] In this embodiment, as shown in Figures 10 and 11, the rotating shaft mechanism 30 includes a rotating shaft 31, a cam 33, and a shift pin 34. The second housing 21 is rotatably connected to the first housing 11 via the rotating shaft 31. The cam 33 is sleeved on the rotating shaft 31 and fixedly connected to the first housing 11. The cam 33 is provided with a plurality of shift teeth 331. The shift pin 34 is fixedly disposed within the second housing 21. When the shift pin 34 engages with any of the shift teeth 331, the rotation angle between the second housing 21 and the first housing 11 is adjusted. The cam 33 is provided with a plurality of shift teeth 331. When the shift pin 34 engages with different shift teeth 331, the rotation angle of the second housing 21 can be adjusted to accommodate different wearers.

[0082] Preferably, as shown in FIG10 , the earphones further include an elastic mechanism 40 movably disposed on the second housing 21 . One end of the elastic mechanism 40 abuts the second housing 21, and the other end abuts the shift pin 34 , allowing the shift pin 34 to move along the length of the second housing 21 , as indicated by arrow a in FIG10 . The shift pin 34 is connected to the second housing 21 via the elastic mechanism 40 . In the worn state, the elastic mechanism 40 acts to maintain the shift pin 34 in an engaged state with the shift tooth 331 , thereby fixing the rotation angle of the second housing 21 and maintaining the clamping portion 20 in a clamped state and clamping the earpiece against the user's auricle. Applying an external force to the shift pin 34 causes the shift pin 34 to overcome the elastic force of the elastic mechanism 40 , disengaging the shift pin 34 from the engaged state with the shift tooth 331 , and allowing the clamping portion 20 to transition from the worn state to the unworn state, thereby enabling the earphones to be stored and worn.

[0083] As shown in Figures 10 and 12, the elastic mechanism 40 includes a spring seat 41 and a spring 42. The spring seat 41 is movably mounted on the second housing 21. The spring 42 is sleeved on the spring seat 41 and abuts the second housing 21 at one end. The shift pin 34 abuts the spring seat 41. A mounting slot may be provided in the second housing 21, and the spring seat 41 is movably mounted in the mounting slot. The spring seat 41 can limit the position of the spring 42 as it expands and contracts.

[0084] In one embodiment, as shown in Figure 10, a plurality of shift teeth 331 are arranged in sequence along the thickness direction of the cam 33, and the heights of the plurality of shift teeth 331 are sequentially decreased along the thickness direction of the cam 33. The shift pin 34 is movable along the width direction of the second shell 21. The shift pin 34 is moved along the width direction of the second shell 21 so that the shift pin 34 cooperates with different shift teeth 331 to adjust the angle between the second shell 21 and the first shell 11.

[0085] The thickness direction of the cam 33 is the direction indicated by arrow b in FIG10 , and the thickness direction of the cam 33 is the width direction of the second housing 21. As shown in FIG10 , three shift teeth 331 are provided along the thickness direction of the cam 33, and the height of the shift teeth 331 decreases sequentially. The shift pin 34 is movable along the width direction of the second housing 21. When the shift pin 34 moves to the corresponding first shift tooth, the clamping portion 20 is rotated counterclockwise to engage the shift pin 34 with the first shift tooth. To increase the clamping space, the shift pin 34 can be moved along the width direction of the second housing 21, thereby engaging the shift pin 34 with the second shift tooth. To further increase the clamping space, the shift pin 34 can be further moved to engage the shift pin 34 with the third shift tooth. In this embodiment, a plurality of gears are designed on the cam 33. By toggling the gear pin 34 by toggling the switch, the gear pin 34 can be engaged with the gear teeth 331 of different gears, thereby adapting to different wearers.

[0086] Furthermore, as shown in FIG12 , a plurality of recessed grooves 411 are provided along the width direction of the second housing 21 on the side of the spring seat 41 that abuts the shift pin 34. A mating portion 341 is provided at the end of the shift pin 34 to engage with the recessed groove 411. When the shift pin 34 moves along the width direction of the second housing 21, the mating portion 341 can be positioned within different recessed grooves 411, and the engagement between the recessed grooves 411 and the mating portion 341 limits the position of the shift pin 34. The number of recessed grooves 411 is the same as the number of shift teeth 331, and the plurality of recessed grooves 411 are provided in a one-to-one correspondence with the plurality of shift teeth 331. When the shift pin 34 is positioned within a recessed groove 411, it can correspond to exactly one shift tooth 331, so that when the clamping portion 20 is rotated, the shift pin 34 can engage with the corresponding shift tooth 331.

[0087] As a variation, multiple shift teeth 331 may also be sequentially arranged along the circumference of the cam 33. For example, three shift teeth 331 are sequentially arranged along the clockwise direction on the outer circumference of the cam 33, namely, the first shift tooth, the second shift tooth, and the third shift tooth. When the rotating shaft 31 drives the shift pin 34 to rotate counterclockwise, the shift pin 34 first engages with the third shift tooth. At this time, the angle between the functional portion 10 and the clamping portion 20 is maximized, and the clamping space of the earphone is also maximized. When the shift pin 34 continues to rotate counterclockwise until it engages with the second shift tooth, the angle between the functional portion 10 and the clamping portion 20 decreases, and the clamping space of the earphone also decreases. When the shift pin 34 continues to rotate counterclockwise until it engages with the first shift tooth, the angle between the functional portion 10 and the clamping portion 20 continues to decrease, and the clamping space of the earphone is minimized. The number of gear teeth 331 described above is merely an example. In actual use, the number of gear teeth 331 can be adjusted as needed. This embodiment does not specifically limit the number of gear teeth 331. In this embodiment, by providing multiple gear teeth 331 along the circumference of the cam 33, the earphone clamping space can also be adjusted, thereby making the earphones suitable for different wearers.

[0088] Example 3

[0089] An earphone with a clip-on design, as shown in Figures 13 to 16, includes a functional portion 10, a clamping portion 20, and a hinge mechanism 30. The functional portion 10 includes a first housing 11; the clamping portion 20 includes a second housing 21. The first housing 11 and the second housing 21 are rotatably connected via the hinge mechanism 30, which is used to adjust and fix the angle between the functional portion 10 and the clamping portion 20 to form a clamping space for clamping the ear. This embodiment differs from the first embodiment in the structure of the hinge mechanism 30. The other structures are the same as those of the first embodiment, and the common parts of this embodiment and the first embodiment are not repeated here.

[0090] In this embodiment, the rotating shaft mechanism 30 includes a rotating shaft 31, a worm 35, a worm wheel 36 and a cam rod 37. The second housing 21 is rotatably connected to the first housing 11 through the rotating shaft 31. The worm 35 is rotatably arranged in the first housing 11. The worm wheel 36 is sleeved on the rotating shaft 31 and can rotate relative to the rotating shaft 31. A tooth portion 361 and a groove 362 are provided on the circumference of the worm wheel 36. The tooth portion 361 is engaged with the worm 35. The cam rod 37 is fixedly arranged on the second housing 21 and cooperates with the groove 362.

[0091] As shown in Figure 13, the functional part 10 also includes a third bracket 13, which is fixedly connected to the first shell 11. The worm 35 and the worm wheel 36 are both arranged in the third bracket 13. As shown in Figures 15 and 16, when wearing the earphones, the clamping part 20 is rotated so that the cam rod 37 on the clamping part 20 is engaged with the groove 362 of the worm wheel 36. Then, the worm 35 is rotated. The rotation of the worm 35 can drive the worm wheel 36 to rotate around the rotating shaft 31, thereby changing the position of the groove 362 on the worm wheel 36 to adjust the rotation angle of the clamping part 20 and achieve stepless adjustment to suit different wearers. As shown in Figure 17, one end of the worm 35 extends out of the first shell 11 and is provided with a handle 38 for rotating the worm 35. Turning the handle 38 can rotate the worm 35.

[0092] Furthermore, as shown in FIG14 , the present invention further includes an elastic mechanism 40, which is movably disposed on the second housing 21. One end of the elastic mechanism 40 abuts the second housing 21, and the other end is connected to the cam rod 37, allowing the cam rod 37 to move along the length of the second housing 21. The elastic mechanism 40 includes a spring seat 41 and a spring 42. The spring seat 41 is movably disposed within the second housing 21. The spring 42 is sleeved on the spring seat 41 and abuts the second housing 21 at one end. The cam rod 37 is fixedly connected to the spring seat 41. The elastic force of the elastic mechanism 40 can cause the cam rod 37 to engage the groove 362 of the worm gear 36. When the clamping portion 20 needs to be reset to the non-wearing state, the elastic force of the elastic mechanism 40 can be overcome by an external force, causing the cam rod 37 to exit the groove 362 of the worm gear 36, thereby resetting the clamping portion 20 to the flattened state.

[0093] As shown in Figures 13 and 14, a limiting groove 363 is also provided on the outer circumference of the worm wheel 36; the tooth portion 361, the groove 362 and the limiting groove 363 are arranged in sequence along the clockwise direction on the outer circumference of the worm wheel 36; in the wearing state, the cam rod 37 is located in the groove 362; as shown in Figure 13, in the non-wearing state, the cam rod 37 is located in the limiting groove 363, and the first side wall 3631 of the limiting groove 363 close to the groove 362 is inclined relative to the horizontal plane and has a pre-pressure on the cam rod 37, so that when the worm 35 rotates, the second shell 21 is always in a horizontal state.

[0094] When the earphones are not being worn, the cam rod 37 is horizontal and engages with the limiting groove 363 on the worm gear 36. The limiting groove 363 exerts a preload on the cam rod 37. Regardless of how the worm 35 adjusts the rotation of the worm gear 36, the cam rod 37 remains within the limiting groove 363, keeping the clamping portion 20 horizontal and the entire earphone in the non-wearing state. To wear the earphones, the clamping portion 20 is rotated counterclockwise, causing the cam rod 37 to exit the limiting groove 363 and engage with the groove 362. When the clamping portion 20 and the rotating shaft 31 rotate together, the worm gear 36 does not rotate. It only rotates when the worm 35 rotates. After the cam rod 37 is engaged with the groove 362, the worm 35 is rotated, which in turn drives the cam rod 37 engaged with the groove 362, which in turn drives the clamping portion 20 to rotate, thereby adjusting the position of the clamping portion 20 to accommodate different wearers.

[0095] In this embodiment, the rotation stroke of the worm wheel 36 is the same as the movement stroke of the cam rod 37 in the limiting groove 363 on the first side wall 3631, that is, when the teeth on the worm wheel 36 move to the top of the worm 35, the cam rod 37 is located at the top of the first side wall 3631, and when the teeth on the worm wheel 36 move to the bottom of the worm 35, the cam rod 37 is located at the bottom of the first side wall 3631, so that no matter how the worm 35 adjusts the rotation of the worm wheel 36, the first side wall 3631 of the limiting groove 363 always has a pre-pressure on the cam rod 37, thereby making the clamping part 20 in a horizontal state, that is, the clamping part 20 is always in a non-wearing state.

[0096] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
