Description

Technical Field

[0001] The utility model relates to the technical field of earphones, and more specifically, to an ear-hook type earphone with multi-directional rotation. Background Art

[0002] Ear-hook type earphones are widely used in the field of portable multimedia due to their small size, light weight, etc. However, there are certain differences in the ear structure sizes of different users, and the existing ear-hook type earphones often cannot adjust the use angle by rotating the whole ear-hook or rotating the ear-hook, resulting in that when some users wear ear-hook type earphones, the sound outlet holes of the earphone body cannot be well aligned with the ear canals of the users, thus affecting the wearing effect and the use experience of the earphones.

[0003] The existing Chinese patent publication number CN220273836U discloses an adjustable earphone, which includes an earphone body and an ear-hook. The earphone body is provided with a first connecting part, and the ear-hook is provided with a second connecting part. The second connecting part is rotationally connected with the first connecting part so that the ear-hook rotates relative to the earphone body; a first positioning part is arranged at the first connecting part, and a second positioning part is arranged at the second connecting part. When the ear-hook rotates relative to the earphone body, the first positioning part and the second positioning part cooperate so that the ear-hook and the earphone body are in different preset angular positions. Similar ear-hook type earphones like this realize the rotation of the ear-hook relative to the earphone body by arranging two or more associated positioning parts. Although similar ear-hook type earphones can rotate the whole ear-hook, the ear-hook cannot be further adjusted in angle by rotation, and it is always difficult to match the ears of different users, and the wearing comfort effect is still lacking.

[0004] At present, there are also some ear-hook type earphones on the market whose ear-hooks can also rotate, but the structures are relatively complex. Similar ear-hook type earphones like the above all require the cooperation of multiple component structures to realize the rotation of the whole ear-hook or the ear-hook, and the assembly cost is relatively high. Summary of the Utility Model

[0005] The utility model provides an ear-hook type earphone with multi-directional rotation, which can not only rotate the whole ear-hook, but also further rotate the ear-hook to adjust the use angle, and the overall number of parts is less, and the assembly cost is lower.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] Provided is an ear-hook type headphone with multi-directional rotation, which includes a first housing, a second housing, an ear hook and a rotation assembly. The first housing and the second housing are buckled to form a receiving cavity for placing the headphone body. The rotation assembly includes a rotating shell, a bushing, a rotating column, a first limiting structure arranged on the bushing and a second limiting structure arranged in the rotating column. The rotating shell is fixed on the first housing through the bushing. A guiding structure is provided on the second housing. While the rotating shell rotates through the guiding structure, it can cooperate with the first limiting structure on the bushing and be fixed to a preset angular position. One end of the rotating column is connected to the rotating shell, and the other end extends out of the receiving cavity and is connected to the ear hook. The ear hook can cooperate with the second limiting structure and rotate within a preset angular range.

[0008] As an improvement, the guiding structure includes guiding strips arranged on the inner wall of the second housing. An arc-shaped groove is provided on the side of the rotating shell opposite to the second housing. The arc-shaped groove slides along the guiding strips to make the whole rotating shell rotate relative to the headphone body.

[0009] Preferably, the side of the rotating shell provided with the arc-shaped groove is an arc-shaped surface.

[0010] Furthermore, the side of the rotating shell opposite to the side provided with the arc-shaped groove is an annular structure. A positioning ring and a positioning column are provided on the first housing. The bushing includes a bushing body, a fixing column arranged in the middle of the bushing body and a pressing ring arranged on the outer periphery of the bushing body. The first limiting structure is arranged on the outer wall of the bushing body. The annular structure is sleeved on the outer periphery of the positioning column and fits with the positioning ring. The bushing body just passes through the annular structure. The inner wall of the annular structure cooperates with the first limiting structure, and the fixing column of the bushing is sleeved on the positioning column, and the pressing ring presses the annular structure.

[0011] Even further, the first limiting structure is a rib arranged on the outer wall of the bushing body. A tooth groove structure is provided on the inner wall of the annular structure in contact with the bushing body. The rib can slide in the tooth groove structure.

[0012] As an improvement, the rotating column is a hollow structure. The second limiting structure includes a through hole arranged at the connection end of the rotating column and the rotating shell and an arc-shaped notch arranged on the through hole. The through hole communicates with the middle of the rotating column. A connection column that can be inserted into the middle of the rotating column is provided at the connection end of the ear hook and the rotating column. A boss matching the size of the through hole is provided at the end of the connection column. A convex block is provided on the outer wall of the boss. The convex block can move within the range of the arc-shaped notch.

[0013] Further, the second limiting structure further includes a positioning hole and a reset member. The positioning hole is arranged on the outer periphery of the through hole, and the reset member is sleeved on the connecting column. A limiting platform is arranged on the outer periphery of the connecting end of the connecting column and the ear hook. The outer diameter of the limiting platform matches the inner diameter of the rotating column, and the limiting platform is provided with a limiting notch. One end of the reset member abuts against the inner side of the through hole and is clamped in the positioning hole, and the other end abuts against the limiting platform and is clamped in the limiting notch.

[0014] Compared with the prior art, the overall number of components of the multi-directionally rotatable ear-hook type earphone of the present invention is less. A guiding structure is directly arranged on the housing to enable the rotating housing to rotate around it, so that the whole ear hook can rotate. At the same time, a first limiting structure is arranged on the bushing for fixing the rotating housing and is matched with the rotating housing to be fixed to a preset angular position, so as to achieve the overall rotation and fixation of the ear hook. In addition, a second limiting structure is arranged in the rotating column connected to the ear hook to cooperate with the ear hook for fixation, so as to further adjust the rotation angle of the ear hook. The ear-hook type earphone can achieve multi-directional rotation, has high adaptability, and has a simple structure and low assembly cost. Brief Description of the Drawings

Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and should not be construed as a limitation to this patent. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0022] As Figures 1 to 6 shown is an embodiment of the multi-directionally rotatable ear-hook type earphone of the present utility model. As Figure 1 shown, the multi-directionally rotatable ear-hook type earphone of this embodiment includes a first housing 11, a second housing 12, an ear-hook 20 and a rotating assembly. The first housing 11 and the second housing 12 are buckled together to form a receiving cavity for placing the earphone body (not shown in the figure). The rotating assembly includes a rotating shell 31, a bushing 32, a rotating column 33, a first limiting structure and a second limiting structure arranged in the receiving cavity. Among them, the first limiting structure is arranged on the bushing 32, and the second limiting structure is arranged in the rotating column 33. The rotating shell 31 is fixed to the first housing 11 through the bushing 32. A guiding structure is provided on the second housing 12, and the rotating shell 31 can rotate through the guiding structure. At the same time, during the rotation of the rotating shell 31, it can also cooperate with the first limiting structure on the bushing 32 and be fixed to a preset angular position; one end of the rotating column 33 is connected to the rotating shell 31, and the other end extends out of the receiving cavity and is connected to the ear-hook 20, and the ear-hook 20 can cooperate with the second limiting structure and rotate within a preset angular range. In actual production applications, the rotating shell 31 and the rotating column 33 can also be integrally formed.

[0023] The overall number of components of the multi-directionally rotatable ear-hook type earphone of the present utility model is relatively small. A guiding structure is directly provided on the housing, enabling the rotating housing 31 to rotate around it, thereby allowing the entire ear-hook to be rotatably adjusted to the usage angle. Meanwhile, a first limiting structure is provided on the bushing 32 that fixes the rotating housing 31 and cooperates with the rotating housing 31 to be fixed to a preset angular position, which can actually be designed according to usage requirements, so as to achieve the effect of the entire ear-hook rotating and being fixed. In addition, a second limiting structure is provided inside the rotating column 33 connected to the ear-hook 20 to cooperate and fix with the ear-hook 20, thereby further adjusting the rotation angle of the ear-hook 20 to match different usage angle requirements. To simplify the component structure, the first limiting structure and the bushing 32 can be integrally formed, and similarly, the second limiting structure and the rotating column 33 can also be integrally formed. This ear-hook type earphone can achieve multi-directional rotation, has a high adaptability, and has a simple structure and a low assembly cost.

[0024] In a preferred embodiment, as Figure 1 , Figure 2 shown, the guiding structure includes a guiding strip 121 provided on the inner wall of the second housing 12. An arc-shaped groove 311 is provided on the side surface of the rotating housing 31 opposite to the second housing 12. The arc-shaped groove 311 slides along the guiding strip 121 to enable the entire rotating housing 31 to rotate relative to the earphone body. By directly providing the guiding strip 121 on the inner wall of the second housing 12 and cooperating with the arc-shaped groove 311 provided on the rotating housing 31, the two can cooperate to rotate to achieve the effect of the entire ear-hook rotating, without the need to add additional guiding component structures. It should be noted that considering the limited space of the accommodation cavity formed after the first housing 11 and the second housing 12 are buckled, in addition to placing the earphone body and the rotating assembly inside, a light guide column, a charging ejector pin, etc. also need to be provided. Therefore, the side surface of the rotating housing 31 provided with the arc-shaped groove 311 is an arc-shaped surface. Correspondingly, the arc-shaped groove 311 can be provided within the maximum range of the arc-shaped surface. In addition, the guiding strip 121 can also be an arc-shaped structure adapted to the arc-shaped groove 311 to make the entire rotation of the ear-hook 20 smoother.

[0025] In an improved embodiment, as Figure 1 , Figure 3 and Figure 4As shown in the figure, on the side opposite to the side where the arc-shaped groove 311 is provided on the rotating shell 31 is an annular structure 312. On the first housing 11, there are a positioning ring 111 and a positioning post 112. The sleeve 32 includes a sleeve body 321, a fixing post 322 provided in the middle of the sleeve body 321, and a pressing ring 323 provided on the outer periphery of the sleeve body 321. At this time, the first limiting structure is provided on the outer wall of the sleeve body 321. Among them, the annular structure 312 is sleeved on the outer periphery of the positioning post 112 and fits with the positioning ring 111. After installation, the rotating shell 31 is not easily loosened. The sleeve body 321 just passes through the annular structure 312. The inner wall of the annular structure 312 cooperates with the first limiting structure, and the fixing post 322 of the sleeve 32 is sleeved on the positioning post 112, thereby being able to fix the rotating shell 31 to the greatest extent. Since the pressing ring is provided on the outer periphery of the sleeve body 321, the outer diameter of the pressing ring is greater than the outer diameter of the annular structure 312. At this time, the pressing ring presses the annular structure 312. This design only uses the sleeve 32 to cooperate with the first housing 11 and the rotating shell 31, and can conveniently and stably complete the clamping and fixing connection between the rotating shell 31 and the first housing 11, with a simple structure and convenient assembly.

[0026] In order to be able to fix the rotation angle of the rotating shell 31, as Figure 3 、 Figure 4 shown, in this embodiment, the first limiting structure is a rib 324 provided on the outer wall of the sleeve body 321. Correspondingly, a tooth groove structure 313 is provided on the inner wall of the annular structure 312 in contact with the sleeve body 321, and the rib 324 can slide in the tooth groove structure 313. It can be understood that the positions of the tooth groove structure 313 and the rib 324 can be interchanged, that is, the first limiting structure can also be a tooth groove structure provided on the outer wall of the sleeve body 321. Correspondingly, a rib is provided on the inner wall of the annular structure 312 in contact with the sleeve body 321. That is to say, the first limiting structure can be integrally formed with the original structure. In actual applications, the length and the number of tooth grooves of the tooth groove structure 313 can be designed according to the use requirements. Without additionally setting component structures, while fixing the rotating shell 31, the fixing structure is improved, and the layout at the preset angular position can be achieved. Specifically, one tooth groove can correspond to one rotation gear of the entire earhook, so as to adapt to the use requirements of different users.

[0027] As an improvement to the above embodiment, as Figure 5 、 Figure 6As shown in the figure, in this embodiment, the rotating column 33 has a hollow structure. Among them, the second limiting structure includes a through hole 331 provided at the connection end of the rotating column 33 and the rotating shell 31, and an arc-shaped notch 332 provided on the through hole 331. The through hole 331 communicates with the middle part of the rotating column 33; a connecting column 21 that can be inserted into the middle part of the rotating column 33 is provided at the connection end of the earhook 20 and the rotating column 33. A boss 211 matching the size of the through hole 331 is provided at the end of the connecting column 21, and a convex block 212 is provided on the outer wall of the boss 211. The convex block 212 can move within the range of the arc-shaped notch 332. That is to say, the second limiting structure is directly formed on one end of the rotating column 33, and the boss 211 and the convex block 212 are correspondingly provided on the connecting column 21 of the earhook 20. It can be understood that the opening size of the through hole 331 should be smaller than the inner diameter size of the rotating column 33 to ensure that the connecting column 21 is located inside the rotating column 33 when inserted. In order to achieve a certain preset rotation angle, the through hole 331 needs to be set as a special-shaped hole. In this embodiment, an arc-shaped notch 332 is provided on the through hole 331. Correspondingly, the end of the connecting column 21 should cooperate with the special-shaped hole to rotate. In this embodiment, a boss 211 is provided at the end of the connecting column 21 to match the rotation of the through hole 331, and a convex block 212 is provided on the outer wall of the boss 211 to move within the range of the arc-shaped notch 332. Then when the user further adjusts the rotation angle of the earhook 20, the unfolding angle of the arc-shaped notch 332 is the rotation angle that the earhook 20 can adjust.

[0028] As a further improvement to the above embodiment, as Figure 1 , Figure 5 and Figure 6 shown, in this embodiment, the second limiting structure is further provided with a positioning hole 333 and a reset member 334. Among them, the positioning hole 333 is provided on the outer periphery of the through hole 331, and the reset member 334 is sleeved on the connecting column 21; a limiting platform 213 is provided on the outer periphery of the connection end of the connecting column 21 and the earhook 20. The outer diameter of the limiting platform 213 matches the inner diameter of the rotating column 33. Then when the connecting column 21 is inserted into the rotating column 33, the earhook 20 can be stably connected. In practical applications, it can also be fixed by other means as long as the earhook 20 can achieve a rotating action. Among them, a limiting notch 214 is provided on the limiting platform 213. One end of the reset member 334 abuts against the inner side of the through hole 331 and is clamped in the positioning hole 333, and the other end abuts against the limiting platform 213 and is clamped in the limiting notch 214, that is, both ends of the reset member 334 are fixed. Then when it is necessary to (re)adjust the angle of the earhook 20, as long as a little external force is applied, the earhook 20 can quickly rebound, and the operation is very convenient. In practical applications, the reset member 334 can adopt a structure such as a return spring.

[0029] The structure of the multi-directionally rotatable ear-hanging type earphone of the utility model is simple, with fewer overall components, and convenient assembly. It can realize the rotation of the whole ear-hanger and can also separately rotate and adjust the ear-hanger. The multi-directional rotation adjustment has a wider applicable range, and the comfort of the user wearing this earphone is also relatively high.

[0030] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly explaining the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
