Description

Technical Field

[0001] The utility model relates to the technical field of earphones, and further relates to an ear-clip type earphone. Background Art

[0002] In recent years, with the continuous improvement of living standards, various electronic products have continuously entered people's daily lives and become an indispensable part of people's work, study and leisure. Among them, headphones are a particularly important type of electronic product. Headphones are a conversion unit that converts the electrical signals received from the self-media player into sound waves audible to the human ear through the speaker. Headphones are increasingly popular among consumers due to their high portability and small size. At the same time, consumers' demand for headphones is getting higher and higher, and consumers' expectations and requirements for headphones are also constantly increasing.

[0003] At present, there are three main forms of ear-clip earphones: one is through elastic deformation of soft glue, the second is to achieve elastic deformation through the combination of memory metal and soft glue, and the third is through micro-deformation of hard glue. The size and structure of human ears vary greatly. When the thickness of the human ear is larger than the ideal value of the design, the deformation variable is too large, resulting in a larger clamping force of the earphone, which reduces the comfort of wearing. When the thickness of the human ear is smaller than the rational value of the design, the deformation variable is too small, resulting in a smaller clamping force of the earphone, which reduces the tightness of wearing. Whether it is soft glue or memory metal, the elastic modulus of the deformation of the whole machine is adjusted by the material. The adjustment is very limited. The adaptability of wearing mainly depends on the internal ear-clip structure of the earphone, and the human ear has different shapes, so the above cannot solve the problem of wearing adaptability for the whole population. Secondly, the wearing of ear-clip earphones is mainly to clamp the ears by breaking the soft glue to produce deformation, or directly forcefully plugging the ears. There is a certain learning cost and wearing risk in the wearing process, and the earphone wearing experience is not ideal.

[0045] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] In one embodiment, the reference specification Figures 1 to 11 The present invention provides an ear-clip earphone, comprising an earphone body 1 and a clamping assembly, wherein the clamping assembly comprises a first clamping arm 2, a second clamping arm 3, a rotating shaft 4 and a telescopic member 5, wherein one end of the first clamping arm 2 is connected to the earphone body 1, and the other end of the first clamping arm 2 is rotatably connected to the second clamping arm 3 through the rotating shaft 4, and the rotating shaft 4 is used to adjust the opening and closing angles of the first clamping arm 2 and the second clamping arm 3, so as to wear the earphone body 1 on the human ear 6. The telescopic member 5 is arranged on the first clamping arm 2, and a tooth groove portion 31 is arranged on the second clamping arm 3. When the second clamping arm 3 rotates relative to the first clamping arm 2, the telescopic member 5 moves close to the tooth groove structure of the tooth groove portion 31, so as to provide rotation damping and produce a sound by impact.

[0047] In this embodiment, the clamping assembly adjusts the opening and closing angles of the first clamping arm 2 and the second clamping arm 3 through the rotating shaft 4. Consumers can find a suitable wearing angle according to their own body shape and ear shape, thereby improving the consumer's wearing experience; at the same time, the second clamping arm 3 can be adjusted to a required angle for easy storage in the charging bin, which can effectively save space; and it can achieve a clicking sound when rotating, which makes users feel that the product is novel and can make the product have obvious differentiation.

[0048] In one embodiment, the reference specification Figures 3 to 9 The end of the first clamping arm 2 is provided with a first connecting member, the first connecting member has a first through hole 211, and the end of the second clamping arm 3 is provided with a second connecting member, the second connecting member has a second through hole 321, and the first through hole 211 and the second through hole 321 are coaxially arranged. The rotating shaft member 4 includes a rotating shaft 41, and the rotating shaft 41 is adapted to be inserted in the first through hole 211 and the second through hole 321, so that the first clamping arm 2 and the second clamping arm 3 are rotatably connected. The first connecting member and the first clamping arm 2 can be fixedly connected or detachably connected; the second connecting member and the second clamping arm 3 can be fixedly connected or detachably connected.

[0049] Specifically, the first connecting member includes a recess 21, and a first through hole 211 passes through the two side walls of the recess 21; the second connecting member includes a convex portion 32, and a second through hole 321 passes through the two sides of the convex portion 32; the convex portion 32 is adapted to be inserted in the recess 21, and the rotating shaft 41 passes through one side wall of the recess 21, the convex portion 32, and the other side wall of the recess 21 in sequence. Of course, the first connecting member can also be set as a convex portion, and the second connecting member can be set as a recess; or the first connecting member can be set as a plurality of recesses arranged at intervals, and the second connecting member can be set as a plurality of convex portions arranged at intervals to match them. The specific connection methods are similar and will not be described in detail here.

[0050] Furthermore, the end of the protrusion 32 is an arc-shaped structure, and the tooth groove portion 31 is arranged at the end of the protrusion 32; the tooth groove portion 31 includes a plurality of parallel and spaced protruding teeth 311, the length direction of the protruding teeth 311 is parallel to the length direction of the rotating shaft 41, and a tooth groove 312 is formed between two adjacent protruding teeth 311, and a tooth head 511 is provided at the end of the telescopic member 5, and the tooth head 511 is adapted to mesh with the tooth groove 312. When the second clamping arm 3 rotates, the tooth groove part 31 on the second clamping arm 3 will drive the telescopic part 5 to move up and down. When the tooth head 511 reaches the tooth peak of the convex tooth 311, the telescopic part 5 will rise to the highest position and continue to rotate. The telescopic part 5 will quickly fall into the tooth valley of the tooth groove 312, producing a certain impact, thereby forming a ticking sound; when the second clamping arm 3 rotates, the telescopic part 5 has only one degree of freedom of axial movement under the limit of the tooth groove part 31. The second clamping arm 3 must apply a certain force to rotate. This force is the hand feeling force, and it is also the damping force of the shaft to ensure the reliability of the ear clip. Several parallel and spaced convex teeth 31 are equivalent to multiple gears. When rotating to any gear, there is a certain retention force. People with large ears retain a larger angle, and people with small ears retain a smaller angle. It has strong compatibility and can be compatible with different ear sizes.

[0051] Furthermore, the number of the convex teeth 311 is 4-10, such as 5, 6, 7, 8, 9, etc. The angle between the bottom of two adjacent tooth grooves 312 and the arc center of the convex portion 32 is 7.5°-15°, and the arc center of the convex portion 32 is also the arc center of the arc-shaped tooth groove portion 31. This structure can satisfy the rotation of the second clamping arm 3 by at least 90°, ensure the range of motion of the second clamping arm 3, and can adapt to more ear shapes. Of course, the specific number of gears can be set according to actual needs. If the number of gears is large, the angle between the two tooth grooves 312 is set to be smaller; if the number of gears is small, the angle between the two tooth grooves 312 is set to be larger.

[0052] Furthermore, the convex portion 32 is also provided with a flange 322, which is located on one side of the tooth groove portion 31. When the second clamping arm 3 and the first clamping arm 2 are located in the same axial direction, the flange 322 is supported on the end of the first clamping arm 2 to limit the rotation of the second clamping arm 3 away from the earphone body 1. By providing the flange 322 to limit the rotation of the second clamping arm 3, the second clamping arm 3 cannot rotate in the opposite direction. Figure 1 As shown, the second clamping arm 3 is straightened to facilitate storage in the charging compartment, which can effectively save space; Figure 2 As shown, when the second clamping arm 3 is bent, it can clamp the human ear to enable the earphone to be worn.

[0053] In this embodiment, the clamping assembly provides damping for the relative rotation between the first clamping arm 2 and the second clamping arm 3 by means of the convex teeth 311 in combination with the multi-speed tooth groove structure, and has a clicking sound and feel, so that the rotation of the second clamping arm 3 is smooth and accompanied by clamping force, the wearing process of the earphones will be smoother and easier to wear, and at the same time, a suitable clamping force for clamping the ears can be provided.

[0054] In one embodiment, the reference specification Figures 5 to 7 The two side wall ends of the concave portion 21 are respectively provided with arcuate convex surfaces 213, and the end of the second clamping arm 3 is provided with two arcuate concave surfaces 33, which are respectively located on both sides of the convex portion 32, and the two arcuate convex surfaces 213 are respectively adapted to be arranged in the corresponding arcuate concave surfaces 33. This structure can guide the second clamping arm 3, making its rotation more stable and the overall structure more stable.

[0055] A limiting boss 411 is provided at one end of the rotating shaft 41, and a limiting plane 412 is provided at the other end of the rotating shaft 41; a first limiting slot hole adapted to the limiting boss 411 is provided at one end of the first through hole 211, and the first limiting slot hole is located on one side wall of the recess 21; a second limiting slot hole 212 adapted to the limiting plane 412 is provided at the other end of the first through hole 211, and the second limiting slot hole 212 is located on the other side wall of the recess 21; the first limiting slot hole and the second limiting slot hole 212 are used to limit the relative rotation between the rotating shaft 41 and the first clamping arm 2. A decorative sheet 42 is also provided at one end of the rotating shaft 41 close to the limiting plane 412, and a notch is provided at the corresponding position of the first clamping arm 2, and the decorative sheet 42 is adapted to be clamped in the notch.

[0056] In this embodiment, by respectively providing a limiting boss 411 and a limiting plane 412 at both ends of the rotating shaft 41, and providing a matching limiting slot on the first clamping arm 2, the rotating shaft 41 and the first clamping arm 2 are relatively fixed, so that the second clamping arm 3 can rotate relative to the first clamping arm 2 along with the rotating shaft 41. This fixed connection method does not require the addition of new fixed connecting parts, and has the advantages of simple structure and easy installation.

[0057] In one embodiment, the reference specification Figure 5 , Figure 8 , Fig. 9 The end of the first clamping arm 2 is provided with a mounting groove 22, and the bottom of the mounting groove 22 has a mounting hole 221. The telescopic member 5 includes a shaft wheel 51, a spring shaft 52, a spring 53 and a snap ring 54. The shaft wheel 51 is provided with a tooth head 511, and the tooth head 511 is used to be adapted to connect with the tooth groove structure of the tooth groove part 31. The spring shaft 52 is fixed to the end of the shaft wheel 51 away from the tooth head 511, and the end of the spring shaft 52 away from the shaft wheel 51 is provided with a snap ring 521. The shaft wheel 51 is adapted to be installed in the mounting groove 22, and the end of the spring shaft 52 away from the shaft wheel 51 passes through the mounting hole 221. The spring 53 is sleeved on the spring shaft 52, and one end of the spring 53 is supported on the shaft wheel 51, and the other end of the spring 53 is supported on the bottom of the mounting groove 22. The snap ring 54 is adapted to be clamped on the clamping groove 521, and the snap ring 54 is located on the back side of the bottom of the mounting groove 22.

[0058] Furthermore, an annular groove 512 is provided at one end of the shaft wheel 51 close to the spring shaft 52, and one end of the spring 53 is adapted to be inserted in the annular groove 512. An arcuate surface is provided at one end of the shaft wheel 51 away from the spring shaft 52, and the tooth head 511 is provided on the arcuate surface, and the arcuate surface is used to fit with the arcuate structure on the second clamping arm 3.

[0059] When the second clamping arm 3 rotates relative to the first clamping arm 2, the principle of the clicking sound is as follows: the spring 53 is in a compressed interference state, which will apply axial pressure to the shaft wheel 51, so that the tooth head 511 on the shaft wheel 51 is tightly fitted with the tooth groove portion 31 on the second clamping arm 3; when the second clamping arm 3 rotates, the tooth groove portion 31 on the second clamping arm 3 will drive the telescopic member 5 to move up and down, and when the tooth head 511 reaches the tooth peak of the convex tooth 311, the telescopic member 5 will rise to the highest position and continue to rotate. The telescopic member 5 will quickly fall into the tooth valley of the tooth groove 312, producing a certain impact, thereby forming a ticking sound; when the second clamping arm 3 rotates, the telescopic member 5 has only one degree of freedom to move axially under the limitation of the tooth groove portion 31, and the second clamping arm 3 must apply a certain force to rotate. This force is the hand-feeling force, and it is also the damping force of the rotating shaft, ensuring the reliability of the ear clip.

[0060] In this embodiment, the tooth head 511 of the telescopic part 5 cooperates with the tooth groove portion 31 on the second clamping arm 3 to achieve damping of the rotation of the second clamping arm 3 and a clicking sound when rotating; this structural design occupies a small space and can achieve the effect under the condition of a diameter of 4mm; the tooth groove portion 31 has a plurality of gear settings to improve the convenience and comfort of product use and enhance the user experience.

[0061] It should be pointed out that the specific structure of the telescopic member 5 is described in accordance with the drawings in the specification. In actual use, other structures may also be adopted as long as the structure can realize the axial movement of the driving tooth head 511. This is only for better illustrating the present invention and should not constitute a limitation to the present invention.

The earphone body 1 is vertically connected to the first clamping arm 2, the earphone body 1 and the first clamping arm 2 are integrally formed, and the connection between the earphone body 1 and the first clamping arm 2 near the ear clamping space is smooth.

[0064] It should be pointed out that the specific structure of the earphone body 1 and the connection structure between the earphone body 1 and the first clamping arm 2 are described in accordance with the drawings in the specification.
