Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to an ear clip-on headphone with a rotatable and adjustable clamping space. Background Technology

[0002] With the continuous development of audio products, headphones have become indispensable in many people's work and life. In pursuit of a more comfortable listening environment, addressing the pain points of current headphone products has become a key development direction for audio products. Among these, while ensuring sound quality, headphone comfort and stability have become primary requirements for users.

[0003] Currently, wireless headphones on the market fall into several popular categories, including traditional in-ear headphones, semi-in-ear headphones, and open-back headphones. Traditional in-ear headphones, because the earbuds are inserted deep into the ear canal, can easily cause ear canal pain after prolonged wear. They can also cause friction damage to the ear canal skin over time, potentially leading to earwax buildup and other ear health problems. Headphones that isolate ambient noise also pose a safety hazard during daily activities. While semi-in-ear headphones avoid the ambient noise safety issues of in-ear headphones, they also have some product drawbacks. Because they don't completely seal the ear canal, they rely on the auricle for support, resulting in relatively less stability. Prolonged wear can still create a relatively closed environment in the ear canal, potentially increasing the frequency of otitis media. Open-back headphones transmit sound through ear hooks, bone conduction, or air conduction technology. The headphones do not enter or compress the ear canal, avoiding potential health problems. The open-back design allows ambient sound to pass naturally, eliminating the need for users to increase volume to mask noise. Furthermore, the weight is distributed across the auricle or temporal bone, reducing the likelihood of pain during prolonged wear.

[0004] Clip-on headphones are a type of open-back headphone. They are secured to the ear by clipping on, allowing for extended wear without inserting into the ear canal. This ensures visibility and reduces bacterial growth in the ear canal. However, the connecting arms between the front and rear modules of existing clip-on headphones generally fall into two categories: 1) Rigid material connection, which cannot deform or deform slightly. This design requires force to pry open and secure to the ear, resulting in a poor user experience and difficulty in wearing; 2) Memory wire connection, where the memory wire's deformation recovery ability weakens after prolonged use, posing a risk of not easily repositioning. Combining these two types of connecting arms, different people have different ear thicknesses, leading to some people wearing them too loosely and others too tightly; they have poor adaptability to different ear shapes, are prone to loosening, and have issues such as sound leakage; and the fixed clamping force cannot adapt to different ear thicknesses, resulting in insufficient comfort. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing an ear clip-on earphone with a rotatable and adjustable clamping space. This ear clip-on earphone divides the connecting arm between the first earphone head and the second earphone head into a first arm and a second arm. A pivot and a spring-loaded component are provided between the first arm and the second arm. Through the pivot and the spring-loaded component, the first arm can rotate forward based on the pivot under the action of external force to expand the clamping space between the first earphone head and the second earphone head. After the external force is removed, the first arm can rotate in the opposite direction based on the pivot to reset. Thus, the ear clip-on earphone can adapt to different ear thicknesses and improve wearing comfort and stability.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an ear clip-on earphone with rotatable and adjustable clamping space, including a first earphone head, a second earphone head, and a connecting arm, wherein the connecting arm is connected between the first earphone head and the second earphone head; the connecting arm includes a first arm portion, a second arm portion, a rotating shaft, and a spring-loaded component, wherein the first arm portion is connected to the first earphone head, and the second arm portion is connected to the second earphone head, the rotating shaft has a first end and a second end, one end of the first arm portion is mounted on the first end of the rotating shaft, and one end of the second arm portion is mounted on the second end of the rotating shaft, wherein the first arm portion can rotate forward based on the rotating shaft under the action of external force to expand the clamping space between the first earphone head and the second earphone head; the spring-loaded component is installed between the first arm portion and the second arm portion to provide a spring-loaded force to the first arm portion, so that the first arm portion can rotate back to its original position based on the rotating shaft after the external force is removed.

[0007] In the above technical solution, the spring-rebound component is a torsion spring, which is fitted outside the middle of the rotating shaft. One end of the torsion spring has a first torsion spring arm, and the other end of the torsion spring has a second torsion spring arm. The first torsion spring arm is connected to the first arm portion, and the second torsion spring arm is connected to the second arm portion.

[0008] In the above technical solution, the second end of the rotating shaft is provided with a fixing block, and one end of the second arm is fixedly installed outside the fixing block; the first end of the rotating shaft is provided with a threaded section, and a nut is provided on the threaded section; one end of the first arm is provided with a rotating part, and a rotating hole is provided inside the rotating part; the first end of the rotating shaft moves through the rotating hole of the rotating part; and the nut is screwed onto the threaded section of the rotating shaft to prevent the rotating shaft from coming loose from the rotating hole of the rotating part.

[0009] In the above technical solution, a washer is also provided on the rotating shaft, and the washer is located between the nut and the rotating part.

[0010] In the above technical solution, the second arm includes an upper shell, a lower shell, and a collar 23. The upper shell and the lower shell are fitted together. Each end of the upper shell and the lower shell has a slot for locking the rotating shaft fixing block. The collar 23 is fitted outside one end of the upper shell and the lower shell.

[0011] In the above technical solution, the first torsion spring arm is connected to the rotating part of the first arm, and the second torsion spring arm is connected to the collar 23 and the upper shell of the second arm, respectively.

[0012] In the above technical solution, a middle wall is provided inside the collar 23, and a collar hole 232 for the rotating shaft to pass through is provided in the middle of the middle wall. An arc-shaped limiting groove is provided on the outer periphery of the middle wall. The rotating part of the first arm is in sliding contact with the collar 23. A limiting block is connected to one side of the rotating part. The limiting block extends into the arc-shaped limiting groove. When the rotating part rotates, the limiting block moves within the arc-shaped limiting groove and is limited in its starting and ending positions by the arc-shaped limiting groove, so as to limit the rotation angle of the first arm.

[0013] In the above technical solution, the first arm includes a first upper arm shell and a first lower arm shell, the first upper arm shell and the first lower arm shell are fitted together, the first earphone head is provided with a first earphone head shell, the first upper arm shell and the first lower arm shell are integrally formed and connected to the first earphone head shell; the second earphone head is provided with a second earphone head shell, the second upper arm shell and the second lower arm shell are integrally formed and connected to the second earphone head shell.

The main control circuit board is electrically connected to the antenna module, the magnetic charging mechanism, and the button, respectively.

[0015] The beneficial effects of this invention are as follows: When using this clip-on earphone, the user only needs to push the first earphone head with their hand to rotate the first arm forward based on the pivot, thereby expanding the clamping space between the first and second earphone heads. Then, the earphone is worn on the ear. After releasing the force pushing the first earphone head, the first arm rotates back to its original position based on the pivot, reducing the clamping space between the first and second earphone heads, thus securing the ear. Therefore, this clip-on earphone can adapt to different ear thicknesses, while improving wearing comfort and stability, avoiding the pressure pain caused by the non-adjustable nature of traditional clip-on earphones. This clip-on earphone is also convenient to operate; users can perform one-handed blind operation when putting on and taking off the earphone. Users can open and close the earphone and adjust the angle by pinching both ends of the ear clip with one hand, without visual assistance or other complicated operating steps.

[0023] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1-5As shown, this utility model is an ear clip-on earphone with a rotatable and adjustable clamping space, including a first earphone head 100, a second earphone head 200, and a connecting arm 300. The connecting arm 300 is connected between the first earphone head 100 and the second earphone head 200, and the shape of the connecting arm 300 is approximately "C". A clamping space for clamping the auricle is provided between the first earphone head 100 and the second earphone head 200. The connecting arm 300 includes a first arm portion 1, a second arm portion 2, a pivot 3, and a spring-loaded component. The first arm portion 1 is connected to the first earphone head 100, and the second arm portion 2 is connected to the second earphone head 200. Part 2 is connected to the second earphone head 200. The rotating shaft 3 has a first end 31 and a second end 32. One end of the first arm 1 is mounted on the first end 31 of the rotating shaft 3, and one end of the second arm 2 is mounted on the second end 32 of the rotating shaft 3. The first arm 1 can rotate forward based on the rotating shaft 3 under the action of external force to expand the clamping space between the first earphone head 100 and the second earphone head 200. The spring member is installed between the first arm 1 and the second arm 2 to provide spring force to the first arm 1 so that the first arm 1 can rotate back to its original position based on the rotating shaft 3 after the external force is removed.

[0025] When using this clip-on earphone, please refer to... Figure 2 The user only needs to push the first earphone head 100 with their hand to rotate the first arm 1 forward based on the pivot 3, thereby expanding the clamping space between the first earphone head 100 and the second earphone head 200. Then, the user can wear the ear-clip headphones on their ear canal. After releasing the force pushing the first earphone head 100, see [link to instructions]. Figure 1 The first arm 1 rotates back to its original position based on the pivot 3, reducing the clamping space between the first earphone head 100 and the second earphone head 200, thus clamping the earlobe. Therefore, this ear-clip earphone can adapt to different ear thicknesses, improving wearing comfort and stability, and avoiding the pressure pain caused by the non-adjustable nature of traditional ear-clip earphones. This ear-clip earphone is easy for users to operate; users can perform blind operation with one hand when putting it on and taking it off. Users can open and close the ear clip and adjust the angle by pinching both ends with one hand, without visual assistance or other complex operating steps. In this embodiment, forward rotation refers to the first earphone head 100 rotating forward (see...). Figure 2 "Open" means turning the head of the first earphone backward, while "reverse rotation" means turning the head of the first earphone backward to reset it. It should be noted that the directions of forward and reverse rotation can also be reversed. For example, forward rotation means turning the head of the first earphone backward to open, while reverse rotation means turning the head of the first earphone forward to reset it.

[0026] like Figures 3-6As shown, the spring-rebound component is a torsion spring 4, which is fitted around the middle of the rotating shaft 3. One end of the torsion spring 4 has a first torsion spring arm 41, and the other end has a second torsion spring arm 42. The first torsion spring arm 41 is connected to the first arm 1, and the second torsion spring arm 42 is connected to the second arm 2. The second end 32 of the rotating shaft 3 is provided with a fixing block 33, and one end of the second arm 2 is fixedly installed outside the fixing block 33. The first end 31 of the rotating shaft 3 is provided with a threaded section 34, and a nut 35 is provided on the threaded section 34. One end of the first arm 1 is provided with a rotating part 11, and a rotating hole 111 is provided inside the rotating part 11. The first end 31 of the rotating shaft 3 moves through the rotating hole 111 of the rotating part 11. The nut 35 is screwed onto the threaded section 34 of the rotating shaft 3 to prevent the rotating shaft 3 from loosening from the rotating hole 111 of the rotating part 11. A washer 36 is also provided on the rotating shaft 3, and the washer 36 is located between the nut 35 and the rotating part 11.

[0027] like Figures 3-7As shown, the second arm 2 includes an upper shell 21, a lower shell 22, and a collar 23. The upper shell 21 and the lower shell 22 overlap each other. Each end of the upper shell 21 and the lower shell 22 has a groove 211 and 221 respectively for locking the fixing block 33 of the rotating shaft 3. The collar 23 is fitted onto the outside of one end of the upper shell 21 and the lower shell 22. Sealing grooves 212 and 222 are provided outside one end of the upper shell 21 and the lower shell 22, and a sealing ring (not shown) is provided between the sealing grooves 212 and 222 and the collar 23. The first torsion spring arm 41 is connected to the rotating part 11 of the first arm 1, and the second torsion spring arm 42 is connected to the collar 23 and the upper shell 21 respectively. The collar 23 has a central wall 231 inside, and the central part of the central wall 231 has a collar hole 232 for the rotating shaft 3 to pass through. The outer periphery of the central wall 231 has an arc-shaped limiting groove 233. The rotating part 11 of the first arm 1 slides in contact with the collar 23. A limiting block 112 is connected to one side of the rotating part 11. The limiting block 112 extends into the arc-shaped limiting groove 233. When the rotating part 11 rotates, the limiting block 112 moves within the arc-shaped limiting groove 233 and is restricted in its starting and ending positions by the arc-shaped limiting groove 233 to limit the rotation angle of the first arm 1. In this embodiment, the included angle of the arc-shaped limiting groove is 90 degrees, so that the first arm 1 can rotate 90 degrees in the positive direction. The first arm portion 1 includes a first upper arm shell 12 and a first lower arm shell 13, which are fitted together. The first earphone head 100 is provided with a first earphone head shell 101, and the first upper arm shell 12 and the first lower arm shell 13 are integrally formed and connected to the first earphone head shell 101. The second earphone head 200 is provided with a second earphone head shell 201, and the second upper arm shell 21 and the second lower arm shell 22 are integrally formed and connected to the second earphone head shell 201.

[0028] like Figures 1-5As shown, the pivot 3 and the spring-loaded component are located in the middle section of the connecting arm 300. A through hole 37 is provided inside the pivot 3, and a wire 5 is provided inside the connecting arm 300, passing through the through hole 37. A speaker module 6 is installed in either the first earphone head 100 or the second earphone head 200, and a main control circuit board 7 and a battery 8 are installed in the other earphone head 100. One end of the wire 5 is connected to the speaker module 6, and the other end is connected to the main control circuit board 7. The main control circuit board 7 is electrically connected to the battery 8. The speaker module 6 is installed inside the first earphone head 100, which also contains a microphone electrically connected to the main control circuit board 7. The main control circuit board 7 and the battery 8 are installed inside the second earphone head 200, which also contains an antenna module, a magnetic charging mechanism 9, and a button 10. The main control circuit board 7 is electrically connected to the antenna module, the magnetic charging mechanism 9, and the button 10, respectively. This invention utilizes modular partitioning, separating the speaker module 6 from the battery module, thus distributing the weight and reducing pain during continuous wear. The battery capacity is also improved compared to ordinary TWS earphones, overcoming the limitations of typical TWS earphone usage time. This ear-clip design does not insert into the ear, avoiding pressure on the ear canal and preventing pressure-related damage caused by ear canal friction. Keeping the ear canal open reduces bacterial growth and prevents the formation of a damp environment, avoiding health problems caused by sweat and oil buildup. The speaker outlet design of this ear-clip design is close to the ear canal, allowing sound to enter the ear unimpeded with minimal sound loss, further reducing sound leakage. It allows ambient sound to enter naturally, eliminating the need for users to increase volume to mask noise and mitigating some safety concerns. The button 10 at the rear of the ear-clip design allows users to control audio output by varying the pressing frequency and duration.

[0029] The above description is merely a preferred embodiment of this utility model. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
