DETAILED DESCRIPTION

[0043] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention are described in further detail below. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0044] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0045] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0046] As the trend of miniaturization of earphones becomes more and more obvious, some earphones are connected to two relatively movable clamping parts through a rotating shaft, so that the two clamping parts can be clamped between the user's auricle to achieve ear-clip wearing, and the two clamping parts can also be "folded" closer to each other to a state for easy storage.

[0047] However, as can be seen from the background technology, when the user wears or stores the earphones, the user needs to repeatedly adjust the two parts of the earphones that can rotate relative to each other. The user needs to take the earphones out of the earphone box (charging box) and unfold the two clamping parts so that the distance between the two clamping parts meets the user's ear insertion. Then, the user needs to place the earphones from between the clamping parts into the clamping space of the earphones. After this step, the user enters a "blind operation" state, and needs to adjust the two clamping parts in a direction close to each other so that the two clamping parts can be stably clamped on the auricle and the back of the ear. Conversely, when the earphones are finished using, the user needs to unfold the two clamping parts again to separate them from the ears, and then "fold" the earphones back to a state that fits the earphone box. This results in many operating steps for the earphones and a complicated operating process, which seriously affects the user's experience.

[0048] In view of this, the present embodiment provides an elastic ear clip mechanism, which arranges an elastic reset component 30 between the first clamping component 10 and the second clamping component 20 so that the two clamping components have a tendency to move toward each other, thereby solving a series of problems such as the inconvenience of taking and placing, and putting on and taking off ear clip-on headphones.

[0049] It should be understood that the elastic ear-clip mechanism can be applied to earphones, specifically the ear-clip earphones mentioned in the background art. The ear-clip earphones can adapt to the wearing habits and ear shapes of different users through excellent flexibility and adjustability.

[0050] like Figure 1-Figure 4 As shown, the elastic ear clip mechanism includes a first clamping member 10 and a second clamping member 20. The first clamping member 10 and the second clamping member 20 are rotatably connected relative to each other. With the first clamping member 10 as a positioning reference, the second clamping member 20 can rotate relative to the first clamping member 10 between a stowed position and an extended position. When the elastic ear clip mechanism is in the stowed position, the second clamping member 20 is closer to the first clamping member 10 than in the extended position, and the distance between the second clamping member 20 and the first clamping member 10 is at the minimum allowable value of the elastic ear clip mechanism. In this state, when the elastic ear clip mechanism is used in an earphone product, the earphone is also suitable for storage in an earphone case. In actual use scenarios, the user can rotate the first clamping member 10 and the second clamping member 20 relative to each other in a predetermined direction to the stowed position, making the overall structure of the earphone more compact and easier to carry and store. This not only saves space when the earphone is not in use, but also prevents damage to the earphone due to accidental collision or squeezing during transportation. When the elastic ear clamping mechanism is in the deployed position, the second clamping member 20 is located further away from the first clamping member 10 relative to the stored position, and the angle between the second clamping member 20 and the first clamping member 10 is greater than the angle when the two are in the stored position. It should be understood that the deployed position of the second clamping member 20 is not specified as a specific position state. As long as the second clamping member 20 is out of the above-mentioned stored position and deployed to the angle between the two is greater than the angle when the two are in the above-mentioned stored position, it can be considered that the second clamping member 20 is in the deployed position. In addition to providing a clamping space for the user's ear to be placed between the first clamping member 10 and the second clamping member 20, the deployed position also allows the first clamping member 10 and the second clamping member 20 to be in a state suitable for the user's ear to wear, ensuring that the earphones are not easily removed during wearing, while providing a comfortable wearing experience.

[0051] On the basis of the above, a limiting structure is further provided between the first clamping member 10 and the second clamping member 20. The limiting structure respectively defines the storage position and the maximum expansion position of the second clamping member 20. Under the constraint of the limiting structure, the second clamping member 20 can only move relative to the first clamping member 10 between the storage position and the maximum expansion position. From the above, it can be understood that a clamping space for accommodating the human ear is formed between the first clamping member 10 and the second clamping member 20. The clamping space passes through the front and back sides of the ear clamping mechanism (such as the attached Figure 1-Figure 2The "front" and "back" indicated by the arrows) allow the user's auricle to extend from the front and back sides of the clamping space to avoid interference between the first clamping member 10 and the second clamping member 20 and the ear. At the same time, the clamping space is located at the end of the first clamping member 10 and the second clamping member 20 (as shown in the attached figure). Figure 1-Figure 2 An opening (inside direction indicated by the arrow) which is also connected to the clamping space is also formed. The opening is used to provide space for the ear to extend into the clamping space or to detach from the ear clamping mechanism from the clamping space.

[0052] The relative rotation of the second clamping member 20 and the first clamping member 10 controls the size of the clamping space. As the second clamping member 20 moves from the expanded position toward the stowed position, it moves closer to the first clamping member 10, and the clamping space gradually decreases. Conversely, as the second clamping member 20 moves from the stowed position toward the maximum expanded position, it rotates away from the first clamping member 10, and the clamping space gradually increases.

[0053] The limiting structure constrains the maximum travel between the first clamping member 10 and the second clamping member 20, reducing user operation difficulty while also preventing damage to the internal components of the earphones due to excessive stretching or compression, thereby reducing the risk of damage to the earphones and extending their service life. Furthermore, in addition to constraining the relative motion range of the second clamping member 20 and the first clamping member 10, the limiting structure also constrains the trajectory of the second clamping member 20's movement relative to the first clamping member 10, providing guidance to the user during use and reducing the difficulty of operating the earphones.

[0054] Please refer to the attached Figures 1-6 The elastic ear clamping mechanism also includes an elastic reset component 30, which is arranged between the first clamping member 10 and the second clamping member 20. It is understandable that the elastic reset component 30 can act on any position of the first clamping member 10 and the second clamping member 20, as long as it is ensured that it does not interfere with the clamping space. Under the action of the elastic reset component 30, the elastic reset component 30 will continue to apply an elastic force from the expanded position to the retracted position to the second clamping member 20 with the first clamping member 10 as the positioning reference, so that the second clamping part has a tendency to move from any expanded position to the retracted position, allowing the elastic ear clamping mechanism to remain stably clamped to the user's ear or in a position convenient for storage in the absence of external force, reducing the number of operating steps during the user's wearing and storage process, improving the compatibility and comfort of wearing, and making the storage of the earphones more convenient.

[0055] In the application of the above-mentioned elastic ear clip mechanism in ear clip headphones, compared to conventional ear clip headphones, this elastic ear clip mechanism has the following advantages: except that during the wearing process, the user needs to apply a force to the first clamping member 10 and the second clamping member 20 that can overcome the action of the elastic reset member 30 to move the second clamping member 20 from the storage position to the expanded position, thereby allowing the ear to be placed in the clamping space, there is no need to adjust the ear clip headphones during subsequent wearing adjustments and detachment. When the ear clip headphones are worn, the first clamping member 10 and the second clamping member 20 can be in a state of pressing against the user's auricle and back of the ear, respectively, under the action of the elastic reset member 30, thereby ensuring stability during the wearing process and avoiding the situation where the ear clip headphones fall off during wearing and the need for repeated adjustment and readjustment during wearing. During the process of removing and storing the clip-on earphones, after the user takes the clip-on earphones off their ears, due to the presence of the elastic reset member, after the first clamping member 10 and the second clamping member 20 lose interference with the ears, the first clamping member 10 and the second clamping member 20 will naturally reset to the storage position. The process does not require user intervention, which effectively reduces the user's operation steps. Afterwards, the user can quickly place it into the earphone box to complete the storage of the clip-on earphones, thereby simplifying the user's wearing, taking off and storage process and improving the user's experience.

[0056] The above structure is used as the basis for the following implementation. Figure 3-Figure 9 The limiting structure includes a first abutting portion 11 provided on the first clamping member 10 and a first limiting portion 21 provided on the second clamping member 20. When the first limiting portion 21 abuts the first abutting portion 11, the second clamping member 20 is in the retracted position. Furthermore, the limiting structure also includes a second abutting portion 12 provided on the first clamping member 10 and a second limiting portion 22 provided on the second clamping member 20. When the second limiting portion 22 abuts the first abutting portion 11, the second clamping member 20 is in the maximum extended position.

[0057] In this embodiment, the limiting structures for constraining the storage position and the maximum expansion position of the second clamping member 20 are respectively set as the first abutting top portion 11 and the first limiting portion 21, and the second abutting top portion 12 and the second limiting portion 22 which are independent of each other. This can reduce the design and processing difficulty of the limiting structure on the first clamping member 10 and the second clamping member 20, and can also simplify the structure of the limiting structure on the first clamping member 10 and the second clamping member 20, thereby avoiding the problem that the structure of the limiting structure on the first clamping member 10 and the second clamping member 20 is too redundant, resulting in a decrease in processing yield and an increase in assembly difficulty.

[0058] At the same time, in the relative movement direction of the first clamping member 10 and the second clamping member 20, the first abutting portion 11 and the second abutting portion 12, as well as the first limiting portion 21 and the second limiting portion 22 are arranged at intervals, that is, on the basis of forming a rotation axis L1 for relative rotation between the first clamping member 10 and the second clamping member 20, the first abutting portion 11 and the second abutting portion 12 are arranged at intervals around the rotation axis L1 on the first clamping member 10, and the first limiting portion 21 and the second limiting portion 22 are arranged at intervals around the rotation axis L1 on the second clamping member 20. In addition, the movement trajectories of the first abutting top portion 11 and the first limiting portion 21 at least partially overlap, and the movement trajectories of the second abutting top portion 12 and the second limiting portion 22 at least partially overlap, and the two movement trajectories do not interfere with each other. In this way, the problem of mutual interference between the first abutting top portion 11 and the second limiting portion 22, and between the second abutting top portion 12 and the first limiting portion 21 during the relative movement of the first clamping member 10 and the second clamping member 20 is avoided, ensuring that the first abutting top portion 11 and the first limiting portion 21 constrain the storage position of the second clamping member 20, and the second abutting top portion 12 and the second abutting top portion 12 constrain the unfolded position of the second clamping member 20.

[0059] Of course, in other embodiments, the first abutting top portion 11 and the second abutting top portion 12, as well as the first limiting portion 21 and the second limiting portion 22 can also be respectively arranged on the same limiting component. For example, in an embodiment in which the limiting structure is an embodiment in which a limiting block and a limiting groove 252 cooperate with each other to realize the limiting function, the first abutting top portion 11 and the second abutting top portion 12 can be respectively set as the opposite two ends of the limiting block, and the first limiting portion 21 and the second limiting portion 22 can be respectively set as the opposite two side groove walls of the limiting groove 252, so that when the limiting block is located in the limiting groove 252 and moves relative to the limiting groove 252, the two can respectively cooperate with each other through the two ends of the limiting block and the two sides of the limiting groove 252, thereby constraining the rotation stroke of the first clamping member 10 and the second clamping member 20.

[0060] Of course, compared with the above embodiment, placing the first abutting top portion 11 and the second abutting top portion 12, and the first limiting portion 21 and the second limiting portion 22 at intervals on the first clamping member 10 and the second clamping member 20 can effectively improve the structural design freedom of the first clamping member 10 and the second clamping member 20 (avoiding the problem of excessive component size caused by the excessive size of the above-mentioned limiting block and the limiting groove 252), making the component structure more compact and improving the portability of the ear-clip headphones in the storage position.

[0061] In one embodiment, the first clamping member 10 and the second clamping member 20 are rotatably connected via a rotating member 40. Specifically, a first hole portion 13 is provided on the first clamping member 10, and a second hole portion 23 is provided on the second clamping member 20. When the first hole portion 13 and the second hole portion 23 are in corresponding communication, the rotating member 40 is inserted into the first hole portion 13 and the second hole portion 23. Since the rotating member 40 in this embodiment is only used to define the rotation axis L1 between the first clamping member 10 and the second clamping member 20, the rotating member 40 needs to maintain a freely rotatable mating relationship with the first hole portion 13 and / or the second hole portion 23 to ensure that the first clamping member 10 and the second clamping member 20 can move toward the storage position under the action of the elastic return component 30.

[0062] It is understood that the first hole portion 13, the second hole portion 23, and the rotating member 40 may be matched with each other in the following manners, but not limited to, as long as the first clamping member 10 and the second clamping member 20 can smoothly rotate between the stored position and the maximum extended position under the action of an external force:

[0063] The rotating member 40 is respectively loosely fitted with the first hole portion 13 and the second hole portion 23;

[0064] The rotating member 40 is interference-fitted with the first hole portion 13 and is clearance-fitted with the second hole portion 23;

[0065] The rotating member 40 is interference-fitted with the second hole portion 23 and clearance-fitted with the first hole portion 13 .

[0066] Of course, in other embodiments, the first clamping member 10 and the second clamping member 20 may also be provided with rotatably compatible rotating structures. For example, the first clamping member 10 and the second clamping member 20 may each be provided with a rotatably compatible rotating shaft and an axial hole, wherein the rotating shaft and the axial hole are respectively integrally formed with the first clamping member 10 and the second clamping member 20.

[0067] As a further embodiment, the elastic reset component 30 also has at least the following two configurations:

[0068] The elastic reset component 30 is partially disposed in the first hole portion 13 , and the other portion of the elastic reset component 30 extends out of the first hole portion 13 and is connected to the second clamping member 20 ;

[0069] A portion of the elastic reset component 30 is disposed in the second hole portion 23 , and another portion of the elastic reset component 30 extends out of the second hole portion 23 and is connected to the first clamping member 10 .

[0070] Based on the above structure, the core idea of ​​the setting method of the elastic reset component 30 is to ensure that it is at least partially arranged in the first hole portion 13 or the second hole portion 23, so that it can act on the first clamping member 10 or the second clamping member 20 through the hole wall of the first hole portion 13 or the second hole portion 23, and in order to ensure that the elastic reset component 30 can act on the first clamping member 10 and the second clamping member 20 at the same time, the other part of the elastic reset component 30 needs to extend from the first hole portion 13 or the second hole portion 23 accordingly. The extended position can be one end of the first hole portion 13 or the second hole portion 23, or it can be a through hole opened on the side of the first clamping member 10 or the second clamping member 20 corresponding to the first hole portion 13 or the second hole portion 23. This embodiment does not strictly limit this. By extending the elastic reset component 30, it can apply an elastic force to the first clamping member 10 and the second clamping member 20 to move toward each other (storage position).

[0071] In this way, the elastic return member can be accommodated in the first hole portion 13 or the second hole portion 23, saving the installation structure reserved for the first clamping member 10 and the second clamping member 20 due to the need to set up the elastic return member. At the same time, since the first hole portion 13 and the second hole portion 23 are in a relatively close position, this setting method also facilitates the elastic return component 30 to act on the first clamping member 10 and the second clamping member 20 respectively, avoiding the problem that the elastic return component 30 is set on the elastic clamping ear mechanism due to a large span distance, resulting in a decrease in structural compactness and occupying more installation space and position, which is not conducive to the installation and layout of other components.

[0072] Continuing with the above embodiment, in one embodiment, the elastic return member 30 is a torsion spring. The torsion spring includes a helical coil 31 and torsion arms 32 extending from each end of the coil 31. The angle between the two torsion arms 32 can be determined based on the angle between the first clamping member 10 and the second clamping member 20 in the stowed position. In some cases, when the second clamping member 20 is in the stowed position, the torsion spring is close to a normal state. That is, in this state, the torsion spring is still in an elastically deformed state, thereby ensuring that the second clamping member 20 can be abutted against the first clamping member 10 by the retaining structure, thereby stably maintaining the stowed position. During the movement of the second clamping member 20 from the stowed position to the maximum extended position, the torsion spring is rotated and compressed by the relative movement of its two torsion arms 32, further generating elastic deformation. As a result, when the second clamping member 20 is released by an external force, the second clamping member 20 can quickly return to the stowed position from the extended position, thereby achieving a stable clamping position on the user's ear and rapid stowage.

[0073] Specifically, the torsion spring is sleeved on the rotating member 40 through the coil 31 to save assembly position and space of the elastic reset component 30, and the two torsion arms 32 of the torsion spring are respectively inserted into the first clamping member 10 and the second clamping member 20.

[0074] In the embodiment in which the elastic reset component 30 is partially arranged in the first hole portion 13, the torsion spring is sleeved on the portion of the rotating member 40 located in the first hole portion 13 through its coil 31, and a torsion arm 32 is inserted into the force hole 50 preset on the hole wall of the first hole portion 13, and the other torsion spring extends from the end of the first hole portion 13 to the second clamping member 20 and is inserted into the force hole 50 preset in the second clamping member 20, thereby achieving the purpose of saving space and ensuring that it continues to act on the first clamping member 10 and the second clamping member 20. In the embodiment in which the elastic reset component 30 is partially arranged in the second hole portion 23, the torsion spring is sleeved on the portion of the rotating member 40 located in the second hole portion 23 through its coil 31, and a torsion arm 32 is inserted into the force hole 50 preset on the hole wall of the second hole portion 23, and the other torsion spring extends from the end of the second hole portion 23 to the first clamping member 10 and is inserted into the force hole 50 preset in the first clamping member 10, thereby achieving the purpose of saving space and ensuring that it continues to act on the first clamping member 10 and the second clamping member 20.

[0075] In this way, most of the torsion spring is accommodated by the first hole portion 13 or the second hole portion 23, and the first clamping member 10 and the second clamping member 20 only need to provide corresponding force holes 50 for the torsion arm 32 of the torsion spring, so that the torsion spring can apply elastic force to the first clamping member 10 and the second clamping member 20 respectively to move from the sub-expanded position to the storage position during the elastic deformation process, without the need for an additional mounting structure. At the same time, because the torsion spring is mounted on the rotating member 40 through its coil 31, the forces exerted by the two torsion arms 32 of the torsion spring on the first clamping member 10 and the second clamping member 20 respectively also tend to be in the direction of the rotation axis L1. The torsion spring is more efficient in transmitting elastic force to the first clamping member 10 and the second clamping member 20, thereby making the force reset and wearing clamping effect of the first clamping member 10 and the second clamping member 20 better. In this way, the ear-clip earphones can also achieve better reset and clamping performance while using a smaller torsion spring, further reducing the volume of the first clamping member 10 and the second clamping member 20, and improving the compactness and integrity of the ear-clip earphones.

[0076] On the basis that the first clamping member 10 and the second clamping member 20 are respectively provided with the first hole portion 13 and the second hole portion 23 and are rotatably connected by the rotating member 40, please continue to refer to the attached Figure 3-Figure 9In one embodiment, a matching first mounting boss 14 and a mounting groove 25 are provided between the first clamping member 10 and the second clamping member 20, and the first hole portion 13 and the second hole portion 23 respectively penetrate the first mounting boss 14 and the mounting groove 25 on both sides of the opposite groove walls.

[0077] It should be understood that in this embodiment, the mounting groove 25 is formed by the cooperation of the two second mounting bosses 24 and the component (the first clamping member 10 or the second clamping member 20) on which the second mounting bosses 24 are located. For example, when the two second mounting bosses 24 are spaced apart from each other on the second clamping member 20, the opposing sides of the two second mounting bosses 24 form the opposing side walls of the mounting groove 25, while the second clamping member 20 forms the bottom of the mounting groove 25.

[0078] The above-mentioned implementation methods mainly include the following two configuration methods:

[0079] The first mounting boss 14 is provided on the first clamping member 10 , and the mounting groove 25 is provided on the second clamping member 20 (i.e., the two second mounting bosses 24 are provided on the second clamping member 20 at intervals);

[0080] The first mounting boss 14 is disposed on the second clamping member 20 , and the mounting groove 25 is opened on the first clamping member 10 (ie, the two second mounting bosses 24 are spaced apart and disposed on the first clamping member 10 ).

[0081] Regardless of the above arrangement, the first mounting boss 14 is at least partially movably positioned within the mounting groove 25 through the notch of the mounting groove 25, so that the first hole 13 extending through the first mounting boss 14 and the second holes 23 respectively provided on the two second mounting bosses 24 can communicate with each other, allowing the rotating member 40 to be rotatably disposed therein. It is understood that the second holes 23 can either extend through the second mounting bosses 24 or be provided only on opposite sides of the two second mounting bosses 24.

[0082] Compared to the embodiment in which the second hole portion 23 is only provided on one side opposite the two second mounting bosses 24, the embodiment in which the second hole portion 23 extends through the two second mounting bosses 24 makes it easier to install the elastic ear clip mechanism. When the first mounting bosses 14 are placed in the mounting grooves 25 and the two pairs of first hole portions 13 are connected to the two second hole portions 23, the rotating member 40 (such as a rotating shaft) can be inserted from the end of one of the second hole portions 23 into the second hole portion 23, the first hole portion 13, and the other second hole portion 23 in sequence. Subsequently, by providing blocking members at opposite ends of the rotating member 40 or at the ends of the two second hole portions 23 that are away from each other, the axial freedom of the rotating member 40 is restricted. Of course, such a configuration also facilitates the disassembly of the elastic ear clip mechanism, thereby reducing the difficulty of disassembly and assembly of the elastic ear clip mechanism and facilitating subsequent inspection and maintenance of the ear clip type headphones.

[0083] As a further structural design of the above embodiment, a limiting structure is arranged between the first mounting boss 14 and the groove wall of the mounting groove 25. The structure included in the limiting structure (such as the above-mentioned first abutment top portion 11, the first limiting portion 21, the second abutment top portion 12 and the second limiting portion 22) can be arranged on any surface of the first mounting boss 14 and the mounting groove 25, so as to ensure that the limiting structure can constrain the storage position and the maximum expansion position of the second clamping member 20, and avoid interference when the second clamping member 20 moves relative to the first clamping member 10 between the above-mentioned two positions.

[0084] By setting the limiting structure between the first mounting boss 14 and the mounting groove 25, the impact of the limiting structure on the appearance of the elastic ear clip mechanism (ear clip headphones) can be reduced, thereby improving the product's aesthetics while ensuring the matching stability of the first clamping member 10 and the second clamping member 20.

[0085] In addition, the first clamping member 10 and the second clamping member 20 are matched through the first mounting boss 14, the two second mounting bosses 24 and the rotating member 40, which can effectively improve the assembly strength between the first clamping member 10 and the second clamping member 20. The first clamping member 10 and the second clamping member 20 maintain a stable matching relationship. In addition to reducing the failure rate of the elastic clamping ear mechanism, it can also allow the second clamping member 20 and the first clamping member 10 to maintain a smoothly rotatable matching relationship, thereby improving the user experience.

[0086] Please continue to refer to the attached Figure 5-Figure 9 As a specific structural form of the above embodiment, the first mounting boss 14 is provided with a first mating surface 141 around the rotation axis of the second clamping member 20, and the bottom of the mounting groove 25 is provided as a second mating surface 251 around the rotation axis, that is, the first mating surface 141 and the second mating surface 251 are respectively formed as an arc surface on the surface of the first mounting boss 14 and the arc surface at the bottom of the mounting groove 25. Through the mutual cooperation of the two arc-shaped mating surfaces arranged around the rotation axis L1, the first clamping member 10 and the second clamping member 20 are realized to rotate relatively stably, thereby avoiding the second clamping member 20 from interfering with the first clamping member 10 when rotating back and forth between the storage position and the maximum expansion position.

[0087] In one embodiment, the first mating surface 141 and / or the second mating surface 251 can also be configured to connect with the surface of the first clamping member 10 and / or the second clamping surface, so that the surface transition between the first clamping member 10 and the second clamping member 20 is smoother, further improving the aesthetics of the clip-on earphone product while also enhancing the user's feel when using the clip-on earphone.

[0088] Please continue to refer to the attached Figure 5-Figure 9In the above-mentioned limiting structure, the first limiting portion 11 and the first limiting portion 21 are respectively arranged on the first mating surface 141 and the second mating surface 251, and the limiting structure is arranged between the first mounting boss 14 and the groove wall of the mounting groove 25 as an example. The first abutting top portion 11 and the first limiting portion 21 for limiting the storage position of the second clamping member 20 are respectively arranged on the first mating surface 141 and the second mating surface 251. Specifically, the second mating surface 251 is also provided with a limiting groove 252 arranged along the movement path of the first limiting portion 21. The first limiting portion 21 is located at one end of the limiting groove 252 and serves as one end groove wall of the limiting groove 252. The first abutting top portion 11 is protruded from the first mating surface 141. It is at least partially arranged in the limiting groove 252, so that when the first clamping member 10 and the second clamping member 20 rotate relative to each other, the first abutting top portion 11 can move along the direction extended by the limiting groove 252, and when the first abutting top portion 11 is fixed to the first limiting portion 21 formed at one end of the limiting groove 252, the second clamping member 20 is in the storage position.

[0089] Of course, the limiting groove 252 can also be configured to be opened on the first mating surface 141, with the first abutting portion 11 formed at one end of the limiting groove 252, and the first limiting portion 21 configured to be protruded from the second mating surface 251 so as to be at least partially located within the limiting groove 252, thereby achieving the same effect. However, compared to the method of protruding the first abutting portion 11 from the first mating surface 141 and opening the limiting groove 252 on the second mating surface 251 to form the first limiting portion 21, this embodiment is more difficult to manufacture (grooving the protruding first mounting boss 14 and arranging the protruding first abutting portion 11 within the concave mounting groove 25).

[0090] Through the above-mentioned setting method, the first abutting top part 11 and the first limiting part 21 can be effectively hidden between the matching surfaces of the first mounting boss 14 and the mounting groove 25, thereby reducing the impact of the limiting structure on the appearance of the product. Especially in products such as clip-on earphones that are relatively small in size and fit the human body, reducing the surface features of the product is particularly important and difficult. This not only determines the user's usage experience when wearing it, but also determines whether the product is beautiful when worn. However, in order to improve the wearing experience and aesthetics, if the limiting structure is cancelled, the second clamping member 20 will be pressed against the first clamping member 10 under the action of the elastic reset member 30, making it difficult to store it. At the same time, the components of the clip-on earphones will be damaged due to overpressure and other conditions, seriously shortening the service life of the clip-on earphones.

[0091] Please continue to refer to the attached Figure 5-Figure 9, and in the embodiment where the above limiting structure includes a second abutting top portion 12 and a second limiting portion 22, and in the state where the second limiting portion 22 abuts against the second abutting top portion 12, the second clamping member 20 is in the maximum deployment position. Due to the cooperation between the first clamping member 10 and the second clamping member 20 through the respectively provided first mounting boss 14 and mounting groove 25, an end face will be formed at the positions where the first clamping member 10 and the second clamping member 20 are respectively used to provide the first mounting boss 14 and form the mounting groove 25. The second abutting top portion 12 and the second limiting portion 22 respectively utilize the above end face and are respectively formed on the end face of the first clamping member 10 and the end face of the second clamping member 20, thereby reducing the influence of the second abutting top portion 12 and the second limiting portion 22 on the appearance of the first clamping member 10 and the second clamping member 20.

[0092] Specifically, when the first mounting boss 14 protrudes from the end face provided by the first clamping member 10, the second abutting top portion 12 is located below the first mounting boss 14. Correspondingly, when the mounting groove 25 is formed in the second clamping member 20, the second limiting portion 22 is formed on one end face of the second clamping member 20 where the mounting groove 25 is formed. During the rotation of the second clamping member 20 from the storage position towards the maximum deployment position, the second abutting top portion 12 and the second limiting portion 22 will gradually move towards each other. And in the state where the second limiting portion 22 abuts against the second abutting top portion 12, the second clamping member 20 is in the maximum deployment position.

[0093] Based on any of the above embodiments, please refer to the appendix Figure 1-Figure 2 , the first clamping member 10 includes an earplug segment 15, a connecting segment 16, and a connecting segment 17 that are connected in sequence. The earplug segment 15 is disposed opposite to the connecting segment 17, that is, the angle between the earplug segment 15 and the connecting segment 16, and the angle between the connecting segment 16 and the connecting segment 17 are approximately 90°, so that the first clamping member 10 is generally in a "C" - shaped structure. It should be noted that the side surfaces of the earplug segment 15, the connecting segment 16, and the connecting segment 17 that are close to each other are transitioned by an arc to improve the comfort of the user's ear during the wearing state. And in one embodiment, the length of the connecting segment 17 is set to be less than that of the earplug segment 15, thereby reserving a corresponding installation position for the second clamping member 20 and ensuring that the elastic ear - clamping mechanism is more compact and portable in the storage position state.

[0094] One end of the second clamping member 20 is rotatably connected to the connecting section 17, allowing the other end of the second clamping member 20 to move toward and away from the earplug segment 15. In the embodiment described above where the connecting section 17 is shorter than the earplug segment 15, when the second clamping member 20 is in its fully extended position, it extends in the same direction as the connecting section 17, facilitating the user's ear entering the clamping space between the earplug segment 15 and the second clamping member 20. When the second clamping member 20 is in the stowed position, it is positioned approximately 90° to the connecting section 17 and opposite the connecting section 16. The end of the second clamping member 20 facing away from the connecting section 17 approaches the earplug segment 15, forming a roughly "mouth"-shaped elastic ear clamping mechanism in this position for easier storage.

[0095] According to the above content, this embodiment also provides an ear-clip type headset, which includes an elastic ear-clip mechanism as described above. In the specific application scenario of the ear-clip type headset, a mainboard is also provided inside the first clamping member 10, and the mainboard includes but is not limited to functional components such as a control chip, a functional chip, and a Bluetooth module. In addition, in the embodiment in which the first clamping member 10 is provided with an electroacoustic transducer, an acoustic cavity and a sound outlet 151 are provided on the first clamping member 10 for the electroacoustic transducer. Specifically, the sound emitted by the electroacoustic transducer transmits the audio signal to the outside through the acoustic cavity and the sound outlet 151. Components such as the electroacoustic transducer and the battery can be connected to the mainboard through a flexible circuit board.
