[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0033] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0034] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0035] like Figure 1 As shown, a retractable ear-clip earphone provided by an embodiment of the utility model comprises an earphone body 1, a clamping body 2 and a retractable structure 4. An electronic component 11 for emitting sound is arranged inside the earphone body 1, a sound outlet 12 for transmitting sound is arranged on the outer wall of the earphone body 1, and the clamping body 2 is movably connected to the earphone body 1, and the clamping body 2 can be bent repeatedly to clamp the helix or loosen. In the clamping state, a clamping area 3 for accommodating the helix is ​​formed between the earphone body 1 and the clamping body 2, and the earphone body 1 and at least part of the clamping body 2 are distributed on both sides of the helix. Specifically, the earphone body 1 is located on the inner side of the helix, and the bent clamping body 2 is at least partially located on the outer side of the same helix, so that the earphone body 1 and the clamping body 2 located on the other side of the helix can clamp the helix together, and the sound can be smoothly transmitted to the helix. The clamping body 2 can be bent repeatedly to clamp the helix or release it. Thus, by bending the clamping body 2, the shape and size of the clamping area 3 can be adjusted, so that the degree of clamping can be adjusted, thereby improving the stability of clamping. Specifically, the material of the clamping body 2 can be a soft material such as silicone or rubber, which has good softness, not only improving the comfort when wearing, but also having high friction performance, thereby increasing the friction between the helix and improving the stability of wearing.

[0036] In some embodiments, Figure 1As shown, the telescopic structure 4 is disposed between the earphone body 1 and the clamping body 2, and the telescopic structure 4 is used to adjust the relative position between the clamping body 2 and the earphone body 1, so that the shape and size of the clamping area 3 can be adjusted to fit the helices of different sizes. That is, the relative position between the earphone body 1 and the clamping body 2 can be adjusted by the telescopic structure 4 according to the actual wearing requirements, and the size of the clamping area 3 can be adjusted as required, so as to meet the wearing requirements of helices of different sizes, so that the wearing range of the ear clip earphone is improved.

[0037] It can be understood that before wearing, the earphone body 1 and the clamping body 2 can be driven to move away from each other to a certain range or to a maximum distance, and the clamping body 2 can be bent until the clamping body 2 is straightened or nearly straightened to form a larger clamping area 3. While maintaining the size of the clamping area 3, the earphone body 1 is placed on the inner side of the helix and the position of the earphone body 1 is kept unchanged, the earphone body 1 and the clamping body 2 are driven to move closer to each other, and the clamping body 2 is bent in the direction close to the earphone body 1 until the earphone body 1 and the clamping body 2 clamp the helix, thereby completing the wearing of the retractable ear clip earphone. When the helix is ​​large in size, the clamping body 2 can be bent in the direction away from the earphone body 1 and / or the earphone body 1 and the clamping body 2 are driven away from each other, so that the clamping area 3 can be enlarged; when the helix is ​​small in size, the clamping body 2 can be bent in the direction close to the earphone body 1 and / or the earphone body 1 and the clamping body 2 are driven to move closer to each other, so that the clamping area 3 can be reduced.

[0038] The embodiment of the utility model provides a retractable ear clip type earphone, comprising an earphone body 1, a clamping body 2 and a telescopic structure 4. Since the clamping body 2 can be bent repeatedly, the clamping area 3 can be enlarged by bending the clamping body 2 in a direction away from the earphone body 1; the clamping area 3 can be reduced by bending the clamping body 2 in a direction close to the earphone body 1. At the same time, the clamping body 2 is movably arranged on the earphone body 1, and the telescopic structure 4 is arranged between the earphone body 1 and the clamping body 2, and is used to adjust the relative position between the earphone body 1 and the clamping body 2. In this way, the clamping area 3 can be enlarged by driving the earphone body 1 and the clamping body 2 away from each other; the clamping area 3 can be reduced by driving the earphone body 1 and the clamping body 2 close to each other. The embodiment of the utility model realizes the adjustment of the shape and size of the clamping area 3 through the combination of the telescopic structure 4 and the clamping body 2 that can be bent repeatedly, so that the retractable ear clip type earphone can adapt to various types of helices, thereby improving the applicability of the retractable ear clip type earphone. Furthermore, the situation that the size of the clamping area 3 does not match the size of the helix when the retractable ear clip type earphone is worn on different helices is avoided, thereby avoiding the problem that the retractable ear clip type earphone is not firmly worn.

[0039] like Figure 1As shown, in some embodiments, a deformable member 22 for adjusting the size of the clamping area 3 by plastic deformation is provided in the clamping body 2. When the clamping body 2 is bent, the deformable member 22 can be plastically deformed so that the shape of the deformable member 22 matches the shape of the clamping body 2 until the size and shape of the clamping area 3 matches the shape and size of the helix. After the size of the clamping area 3 is adjusted by the clamping body 2, the deformable member 22 is used to keep the shape and size of the clamping body 2 unchanged, so as to keep the size and shape of the clamping area 3 unchanged, so that the clamping body 2 and the earphone body 1 can clamp the helix. Among them, the deformable member 22 can be a steel plate or a plurality of steel wires arranged in parallel and spaced apart. The steel plate and the steel wire are easy to manufacture, which reduces the production cost.

[0040] like Figure 2 As shown, in some embodiments, a deformation structure 23 is provided on the clamping body 2, and the deformation structure 23 reduces the elastic deformation generated by the bent clamping body 2, thereby reducing the restoring force generated by the elastic deformation of the clamping body 2 for restoring the elastic deformation. In this way, the bending degree of the clamping body 2 is improved, thereby expanding the range of size change of the clamping area 3, so that the ear clip type earphone can adapt to more sizes of earlobes; it also reduces the external force of bending the clamping body 2, making the operation more convenient; it also prevents the clamping body 2 from being deformed due to the restoring force after wearing, avoiding multiple adjustments. Specifically, along the first direction, at least the deformation structure 23 is provided on the clamping body 2 corresponding to the deformation member 22, so that at least the corresponding part of the deformation member 22 on the clamping body 2 can increase the bending degree. After the size of the clamping area 3 is adjusted, the restoring force generated by the elastic deformation of the clamping body 2 is not enough to drive the deformation of the deformation member 22, thereby avoiding the size change of the clamping area 3. Along the second direction, the size of the deformable structure 23 matches the size of the clamping body 2, so that the clamping body 2 can be fully covered with the deformable structure 23 in the second direction, thereby further reducing the elastic deformation of the clamping body 2 when bending, increasing the bending degree of the clamping body 2, and expanding the adjustable size range of the clamping area 3. Figure 2 The direction indicated by A1 is the direction parallel to the central axis from one end to the other end of the clamping body 2. The second direction is Figure 2 The direction indicated by A2 is the width direction from one side of the clamping body 2 to the other side.

[0041] like Figure 2As shown, in some embodiments, the deformation structure 23 is configured as a groove, which is disposed on the outer wall of the clamping body 2; and / or, the deformation structure 23 is configured as a cavity, which is formed inside the clamping body 2. When the clamping body 2 is bent, the deformation on the outer wall of the clamping body 2 can be reduced by the groove disposed on the outer wall of the clamping body 2, so as to reduce the restoring force generated by the clamping body 2 for restoring the deformation, thereby increasing the bending degree of the clamping body 2. By providing the cavity inside the clamping body 2, the deformation generated inside the clamping body 2 can be reduced, and the restoring force generated by the clamping body 2 for restoring the deformation when the clamping body 2 is bent can also be reduced, thereby increasing the bending degree of the clamping body 2. In addition, the configuration of the groove and the cavity enables the retractable ear clip-on earphone to have different hand feel and appearance, providing customers with more choices.

[0042] Specifically, the arrangement of the groove and the cavity in this embodiment includes but is not limited to one or more of the following embodiments:

[0043] like Figure 2 As shown, in a possible embodiment, at least the clamping body 2 is used to form a clamping surface 24 of the clamping area 3 (refer to Figure 1 ) and / or the back side 25 facing away from the clamping surface 24 (reference Figure 1 ) is provided with a deformation structure 23. When the clamping body 2 is bent, the deformation amount generated by the clamping surface 24 and the back surface 25 is the largest. Providing the deformation structure 23 on the clamping surface 24 and / or the back surface 25 can maximize the bending degree of the clamping body 2.

[0044] like Figure 2 As shown, in a possible implementation, the deformation structure 23 is a groove, which extends along the second direction until it covers the outer wall of the clamping body 2, and is provided in plurality along the first direction, with two adjacent grooves spaced apart and arranged in parallel. Not only can the bending degree of the clamping body 2 be further improved, but the protrusion formed between the two adjacent grooves can also increase the friction between the clamping body 2 and the outer side of the helix, thereby making the wearer more secure.

[0045] In a possible implementation, the deformation structure 23 is a groove, which is wound around the clamping body 2 to form a spiral structure. Figure 2 The direction indicated by A1 in the figure is extended to a suitable position, thereby improving the bending deformation performance of the clamping body 2. The arrangement of the grooves in this way presents another appearance, enriches the shape of the clamping body 2, and allows customers to choose retractable ear clip headphones with different appearances according to their preferences.

[0046] In a possible implementation, the deformation structure 23 is a cavity, and a plurality of cavities are provided, and two adjacent cavities are provided at intervals, and each cavity is evenly distributed inside the clamping body 2. The arrangement of the cavities in this embodiment makes it possible that when the clamping body 2 is bent, the elastic deformation of the entire clamping body 2 at the location of the cavity disappears, thereby reducing the restoring force of the entire clamping body 2 to restore the elastic deformation.

[0047] like Figure 1 and Figure 3 As shown, in some embodiments, the telescopic structure 4 includes a slider 41 and a sliding channel 42, the slider 41 is arranged on one of the earphone body 1 and the clamping body 2, the sliding channel 42 is arranged on the other of the earphone body 1 and the clamping body 2, and the slider 41 is movably arranged in the sliding channel 42 to be able to slide and adjust the relative position between the clamping body 2 and the earphone body 1. Specifically, the side wall of the slider 41 is fitted with the inner wall of the sliding channel 42, so that the slider 41 is slidably connected with the sliding channel 42. In this way, not only the sliding channel 42 plays a guiding role, but also the structure is compact, and the overall size of the telescopic ear clip type earphone is prevented from being too large.

[0048] It should be noted that the embodiment of the utility model does not limit the cross-sectional shape of the slider 41 and the sliding channel 42, as long as the slider 41 and the sliding channel 42 are slidably connected. The cross-sectional shape of the slider 41 and the sliding channel 42 can be circular, and when the earphone body 1 and the clamping body 2 are clamped on the helix, the earphone body 1 and the clamping body 2 are restricted from rotating by the helix. In addition, the cross-sectional shape of the slider 41 and the sliding channel 42 can also be triangular, rectangular or polygonal, so that the relative rotation between the earphone body 1 and the clamping body 2 is restricted, thereby improving the stability of the retractable ear clip earphone when worn.

[0049] In some embodiments, along the length direction of the sliding channel 42, a plurality of limiting protrusions are provided on the inner wall of the sliding channel 42 and one of the sliders 41, and a plurality of limiting recesses are provided on the inner wall of the sliding channel 42 and the other of the sliders 41. Among them, at least one limiting protrusion is located in at least one limiting recess to limit the relative position between the clamping body 2 and the earphone body 1. By applying an external force to the earphone body 1 and / or the clamping body 2 along the length direction of the sliding channel 42, the slider 41 moves, and each limiting protrusion and each limiting recess moves along the length direction of the sliding channel 42, thereby adjusting the relative position between the earphone body 1 and the clamping body 2, and the size of the clamping area 3.

[0050] Specifically, the limiting protrusions can be set to be spherical, and a smoothly transitional curved surface is set between two adjacent ones, so as to avoid the situation of getting stuck when the slider 41 is moved.

[0051] like Figure 1 and Figure 3 As shown, in some embodiments, the telescopic structure 4 further includes an elastic member 43, which is disposed in the sliding channel 42 and connected to the slider 41. The elastic member 43 is used to always drive the clamping body 2 and the earphone body 1 to approach each other. After the earphone body 1 and the clamping body 2 are clamped on the helix, the elastic member 43 always generates elastic force to keep the clamping body 2 and the earphone body 1 in a trend of approaching each other, thereby providing a clamping force to clamp the retractable ear clip-type earphone on the helix, so that the retractable ear clip-type earphone can be worn on the helix stably. In addition, when there is a gap between the edge of the helix and the retractable ear clip-type earphone, the elastic member 43 can also drive the clamping body 2 and the earphone body 1 to approach each other, thereby adaptively eliminating the above-mentioned gap, thereby improving the wearing stability.

[0052] In some embodiments, an internal thread is provided on the inner wall of the sliding channel 42, and an external thread is provided on the slider 41, and the internal thread and the external thread are meshed and connected. The slider 41 can be moved in the sliding channel 42 by relative rotation between the earphone body 1 and the clamping member, thereby adjusting the relative position between the earphone body 1 and the clamping body 2. In addition, the threaded connection method has the advantages of simple structure, reliable connection, and convenient assembly and disassembly.

[0053] In some embodiments, a plurality of ratchets are provided on the slider 41 along the length direction of the sliding channel 42, and a ratchet that can be switched between a limit position and a non-limit position is movably provided on the inner wall of the sliding channel 42. The ratchet is rotatably connected to the inner wall of the sliding channel 42 so that the ratchet can be switched between the limit position and the non-limit position by rotation. The limit end of the ratchet is provided on the inner side of the sliding channel 42 and abuts or separates from the ratchet, and the unlocking end of the ratchet is provided on the outer side of the sliding channel 42. When the ratchet is in the limit position, the ratchet abuts against the ratchet, thereby limiting the movement of the slider 41 in the sliding channel 42, thereby limiting the relative position between the earphone body 1 and the clamping body 2. When the ratchet is in the non-limit position, the ratchet separates from the ratchet, and the slider 41 can slide in the sliding channel 42, thereby adjusting the relative position between the earphone body 1 and the clamping body 2.

[0054] like Figure 3 As shown, in some embodiments, a limiting groove 421 is provided on the inner wall of the sliding channel 42, and the limiting groove 421 extends along the length direction of the sliding channel 42. A protrusion 411 matching the limiting groove 421 is provided on the slider 41, and the protrusion 411 is located in the limiting groove 421. Through such a configuration, the length of the limiting groove 421 limits the maximum sliding displacement of the protrusion 411, thereby preventing the slider 41 from sliding out of the sliding channel 42, thereby preventing the earphone body 1 from being separated from the clamping body 2 during use.

[0055] like Figure 4 and Figure 5 As shown, in some embodiments, a plurality of limit grooves 421 are evenly arranged along the circumference of the sliding channel 42, and two adjacent limit grooves 421 are arranged in parallel and at intervals. The plurality of limit grooves 421 evenly arranged along the circumference of the sliding channel 42 make the force on the slider 41 more uniform, make the movement of the slider 41 more stable, and avoid the occurrence of jamming and other faults of the telescopic structure 4 during use.

[0056] like Figure 1 As shown, it should be noted that the electronic assembly 11 in this embodiment includes all electronic components except the battery 5, such as the sound module 111 and the PCB board 112. After the retractable ear clip earphone is worn, the earphone body 1 is located on the inner side of the helix, so that the electronic assembly 11 is located on the inner side of the helix, so that the weight of the electronic assembly 11 is borne by the helix, so that the retractable ear clip earphone is worn more stably and not loose. Specifically, after the retractable ear clip earphone is worn, the earphone body 1 is located in the concha cavity, so that the concha cavity plays a role in fixing the earphone body 1, further making the retractable ear clip earphone worn more firmly.

[0057] like Figure 1 As shown, in some possible embodiments, the retractable ear clip earphone further includes a battery 5 for powering the electronic component 11, and the battery 5 is disposed in the earphone body 1 adjacent to the electronic component 11 and is electrically connected to the electronic component 11. In this way, all electronic components are disposed in the earphone body 1, and no electronic components are disposed in the clamping body 2, which not only makes the weight of all electronic components borne by the helix, thereby making the wearing more stable; it also reduces the pressure on the helix when worn, and improves the comfort; in addition, it also avoids the feeling of falling on the outer side of the helix, thereby improving the use experience.

[0058] like Figure 6 As shown, in some other possible embodiments, the retractable ear clip earphone further includes a battery 5 for powering the electronic component 11, the battery 5 is arranged in the clamping body 2, the deformable member 22 is located between the battery 5 and the earphone body 1, and the battery 5 is electrically connected to the electronic component 11. By arranging the battery 5 in the clamping body 2, the volume of the part of the clamping body 2 for mounting the battery 5 is enlarged, which, on the one hand, increases the contact area between the clamping body 2 and the outer side of the helix, thereby improving the stability when worn; on the other hand, another appearance of the retractable ear clip earphone is provided, thereby satisfying the preferences of different people for different appearances.

[0059] like Figure 7As shown, in some possible embodiments, a hollow structure 21 is provided on the clamping body 2, and the hollow structure 21 penetrates the clamping body 2 along the thickness direction of the clamping body 2. By providing the hollow structure 21, the skin located in the hollow structure 21 can be exposed when worn, thereby improving the air permeability of the retractable ear clip type earphone, thereby improving the comfort when worn. Specifically, one or more hollow structures 21 can be provided. When the clamping body 2 is in a straightened state, the hollow structure 21 can be circular, rectangular, triangular, elliptical, etc., and can even be an irregular shape when observed along the thickness direction of the clamping body 2. By providing the hollow structure 21 as described above, the hollow structure 21 is both functional and decorative, which not only improves the comfort when worn, but also enables the retractable ear clip type earphone to have different appearances, thereby meeting the aesthetic needs of different people.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
