Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0033] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7According to an embodiment of the present invention, the earphone 100 includes a headband 101, an ear shell 102, and an elastic member 201. The headband 101 includes a rotating shaft 202. The ear shell 102 is provided with a first through hole 203, and the rotating shaft 202 passes through the first through hole 203. The ear shell 102 can rotate around the central axis of the rotating shaft 202 and tilt relative to the central axis of the rotating shaft 202. The elastic member 201 is sleeved on the rotating shaft 202, one end of the elastic member 201 is connected to the headband 101, and the other end of the elastic member 201 is connected to the ear shell 102. The elastic force of the elastic member 201 is used to drive the rotating shaft 202 to reset so that the central axis of the first through hole 203 coincides with the central axis of the rotating shaft 202. In this way, the earphone 100 of the embodiment of the present invention is provided with an elastic member 201 between the auricle 102 and the headband 101. When the earphone 100 is worn, the auricle 102 can be adaptively tilted according to the head shape. After the elastic member 201 is deformed, the elastic force will drive the rotating shaft 202 to reset, that is, drive the auricle 102 to return to its original state. Therefore, after the user wears the earphone 100, the elastic member 201 applies a restoring elastic force to the auricle 102 and the rotating shaft 202, so that it has a tendency to return to its original state. The elastic force makes the auricle 102 press against the user's head or auricle, so that the auricle 102 has a closer fit with the human body, is not easy to get loose when worn, and has a better wearing effect.

[0034] It should be noted that the reference Figure 2 In some embodiments of the present invention, the elastic member 201 is connected to the headband 101 and the auricle 102 in a detachable manner. When the auricle 102 is tilted relative to the rotation shaft 202, the elastic member 201 will respectively abut the auricle 102 and the headband 101, thereby deforming to generate an elastic force for driving the rotation shaft 202 to return to its original position.

[0035] It should be noted that the reference Figure 2 、 Figure 6 and Figure 7 In some embodiments of the present invention, the elastic member 201 is respectively connected to the shaft sleeve 204 and the shaft 202. However, since the shaft sleeve 204 is fixedly mounted on the auricle 102, the elastic member 201 actually still serves the purpose of connecting to the auricle 102. When the auricle 102 tilts relative to the shaft 202, the elastic member 201 can still deform and drive the shaft 202 to return to its original position.

[0036] refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 7In some embodiments of the present invention, a receiving groove 301 is formed on the outer circumferential surface of the rotating shaft 202. The elastic member 201 is sleeved on the end of the rotating shaft 202 away from the headband 101, and at least a portion of the elastic member 201 is disposed within the receiving groove 301. Placing at least a portion of the elastic member 201 within the receiving groove 301 can improve the installation stability of the elastic member 201. Sleeving the elastic member 201 on the end of the rotating shaft 202 away from the headband 101 allows the elastic member 201 to be disposed within the concha 102, thereby improving the aesthetics of the earphone 100. Furthermore, a rotating shaft sleeve 204 can be provided to enclose both the rotating shaft 202 and the elastic member 201. By fixedly connecting the rotating shaft sleeve 204 to the concha 102, the elastic member 201 abuts against the rotating shaft sleeve 204, thereby still achieving the technical effect of driving the concha 102 to return to its original position. It should be noted that in some embodiments of the present invention, the elastic member 201 can also be arranged between one end of the rotating shaft 202 connecting the headband 101 and the auricle 102, which can also play the technical effect of driving the rotating shaft 202 to reset relative to the auricle 102, and can be fixedly connected to the auricle 102 and the headband 101 around the rotating shaft 202 instead of being mounted on the rotating shaft 202.

[0037] refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 7 In some embodiments of the present invention, the rotating shaft 202 includes a first section 302 and a second section 303 connected to each other, the first section 302 has a first end 304 and a second end 305, the first end 304 is connected to the headband 101, and the second end 305 is connected to the second section 303. From the first end 304 to the second end 305, the diameter of the first section 302 gradually decreases, and the diameter of the second section 303 is larger than the diameter of the second end 305 to form a receiving groove 301. The diameter of the first through hole 203 is larger than the diameter of the first end 304, and the elastic member 201 is sleeved on the second section 303. Compared to a traditional cylindrical design with a uniform diameter, the gradually decreasing, angled design allows the ear shell 102 greater room for movement after being mounted on the shaft 202, enhancing the ear shell 102's freedom of movement. Furthermore, the larger diameter of the first through-hole 203 than the first end 304 ensures that the ear shell 102 can be smoothly mounted on the shaft 202. A certain gap exists between the inner circumference of the first through-hole 203 and the outer circumference of the first end 304, providing room for the ear shell 102 to swing. The larger diameter of the second section 303 prevents the elastic member 201 from falling off. The second section 303 provides space for the elastic member 201 to mount and forms a receiving groove 301 for the elastic member 201, enhancing the secure installation of the elastic member 201.

[0038] It should be noted that the reference Figure 4 and Figure 7In some embodiments of the utility model, the hole diameter of the elastic member 201 at both ends is different, the hole diameter of the elastic member 201 at the end close to the headband 101 is larger than the hole diameter of the elastic member 201 at the end far from the headband 101, and the design is to adapt to the inclined design of the first section 302, so that the elastic member 201 has a certain space for movement after being sleeved on the rotating shaft 202, and the deformation and rebound effect are not affected by being too tight.

[0039] It should be noted that, with reference to Figure 3 In some embodiments of the utility model, the first section 302 is provided with a small section of cylindrical surface with constant diameter at both ends, which is to adapt to the installation requirements of the ear shell 102, the rotating shaft sleeve 204 and the elastic member 201, improve the adaptability of the rotating shaft 202 structure, and the specific length can be adjusted during the manufacturing process without affecting the technical effect of the inclined design of the first section 302.

[0040] With reference to Figure 3 And Figure 7 In some embodiments of the utility model, the outer circumferential surface of the second section 303 far from the headband 101 is an arc surface, and the surface of the second section 303 towards the headband 101 is a plane perpendicular to the central axis of the rotating shaft 202. Since the diameter of the second section 303 is larger than the diameter of the second end 305, in order to make the elastic member 201 stable after installation, the hole diameter of the elastic member 201 is slightly smaller than the diameter of the second section 303, and the end of the second section 303 far from the headband 101 is provided with an arc surface curved towards the headband 101, which facilitates the installation of the elastic member 201 on the rotating shaft 202. When the elastic member 201 is sleeved on the rotating shaft 202 from the direction of the second section 303, the arc surface facilitates the gradual deformation of the inner hole of the elastic member 201, avoids the damage of the elastic member 201 due to severe deformation, and affects the rebound elasticity. The surface of the second section 303 towards the headband 101 is provided with a plane, which is to make the elastic member 201 more stable after installation, and the plane can abut against the end surface of the elastic member 201 to avoid its falling off from the rotating shaft 202.

[0041] With reference to Figure 4 And Figure 7In some embodiments of the utility model, the first circular arc groove 401 is circular annular, the outer diameter of the first circular arc groove 401 is greater than the diameter of the second section 303, and the inner diameter of the first circular arc groove 401 is less than the diameter of the second section 303. Such design can improve the elasticity of the elastic member 201, the arc shape of the first circular arc groove 401 can provide space for the deformation of the elastic member 201, reduce the internal stress generated by the elastic member 201, convert it into elastic potential energy, and the inner and outer diameters of the first circular arc groove 401 are respectively arranged on both sides of the outer diameter of the second section 303, so that when the headband 101 and the rotating shaft 202 are relatively inclined, the outer edge of the second section 303 is often the part that exerts the greatest pressure on the elastic member 201, and the circular arc groove arranged on the side corresponding to the contact position of the elastic member 201 and the outer edge of the second section 303 can well release the internal stress of the elastic member 201.

[0042] It should be noted that in some embodiments of the utility model, the material of the elastic member 201 is silica gel, which has good resilience and can quickly return to its original shape after being subjected to external force. When subjected to external force, the molecular chain of silica gel will deform to a certain extent, but when the external force is removed, the molecular chain can quickly return to its original state, thereby exhibiting good resilience, so that the silica gel can effectively absorb energy and reduce vibration when subjected to impact or extrusion, thereby playing a role in shock absorption and buffering. In addition, silica gel can also provide good support, the rebound force after deformation is moderate, and the wearing comfort of the earphone 100 is improved. In some embodiments of the utility model, the elastic member 201 can also be made of thermoplastic elastomer, thermoplastic polyurethane, high-rebound sponge, spring, etc.

[0043] Reference Figure 2 , Figure 7 , Figure 8 and Figure 9 In some embodiments of the utility model, the earphone 100 further comprises a rotating shaft sleeve 204, which is detachably fixed in the ear shell 102, and the rotating shaft sleeve 204 is sleeved on the outer periphery of the elastic member 201. The rotating shaft sleeve 204 is fixed in the ear shell 102, and the elastic member 201 is arranged in the rotating shaft sleeve 204, so that the elastic member 201 can transmit the rebound force to the ear shell 102 through the rotating shaft sleeve 204 when deformed, and the rotating shaft sleeve 204 can make the elastic member 201 arranged in the ear shell 102 more firmly, and the detachable connection is convenient for disassembly and replacement of consumables such as the elastic member 201.

[0044] It should be noted that reference Figure 2 and Figure 9In some embodiments of the utility model, symmetry design of pivot sleeve 204 can be more convenient to disassemble and assemble elastic piece 201, and cavity for placing elastic piece 201 is simultaneously facilitated to manufacture. In some embodiments of the utility model, two pivot sleeves 204 are respectively installed in ear shell 102 through four symmetrically designed bolts, the bolt is simple in structure, strong in locking force, and pivot sleeve 204 is avoided from loosening during use.

[0045] Reference Figure 8 And Figure 9 In some embodiments of the utility model, the outer circumferential surface of the pivot 202 is provided with a limiting groove 901, the limiting groove 901 is arranged along the extension direction of the headband 101, the pivot sleeve 204 comprises a body part 902 and a protruding part 903 which are connected with each other, the protruding part 903 protrudes relative to the inner circumferential surface of the body part 902, and the protruding part 903 is arranged in the limiting groove 901. If the limiting groove 901 is not arranged, the ear shell 102 can rotate circumferentially with the pivot 202 as the axis, but in actual use, the ear shell 102 often does not need to rotate with such a high degree of freedom, therefore, the limiting groove 901 is arranged, so that the ear shell 102 cannot rotate with such a large amplitude, but can swing and tilt by a certain angle along the slotting direction of the limiting groove 901 based on the gap between the pivot 202 and the first through hole 203, which is more in line with the actual requirements in the process, and the limiting groove 901 is also arranged along the extension direction of the headband 101, which is also based on the actual use scene requirements. During the use of the earphone 100, the user only needs to swing the ear shell 102 along the direction of the headband 101 to adapt to different shapes of the pinna, and the arrangement of the limiting groove 901 to reduce the appropriate degree of freedom can obtain better stability and use experience of the earphone 100.

[0046] Reference Figure 1 、 Figure 2 、 Figure 8 And Figure 9In some embodiments of the present invention, the earphones 100 further include an audio cable 103 and a protective cover 205. The concha 102 defines a second through-hole extending along the extension direction of the headband 101. A snap-fit ​​block 904 is disposed within the concha 102, spaced apart from the second through-hole. The protective cover 205 includes a circular ring portion 206 and a snap-fit ​​portion 207, which are interconnected. The circular ring portion 206 passes through the second through-hole, and the snap-fit ​​portion 207 snaps between the second through-hole and the snap-fit ​​block 904. One end of the audio cable 103 is disposed within the concha 102, while the other end of the audio cable 103 passes through the protective cover 205 and is exposed outside the concha 102. The protective cover 205 protects the bend of the audio cable 103, reduces direct contact between the audio cable 103 and the concha 102, and improves its bending resistance, preventing fatigue and damage caused by frequent bending during use, thereby enhancing durability. The provision of a snap-fit ​​block 904 within the auricle 102 and snapping the snap-fit ​​portion 207 of the protective cover 205 therein can prevent the protective cover 205 from loosening during use, thereby improving the stability of the internal structure. In some embodiments of the present invention, the annular portion 206 and the second through hole are interference-fitted, and the audio cable 103 is also tightly fitted to the inner circumferential wall of the annular portion 206. This design allows the protective cover 205 to block the second through hole, isolating the auricle 102 from the external environment, reducing the impact of the external environment on the sound-generating unit within the auricle 102, and improving the sound quality. The second through hole is opened along the extension direction of the headband 101 also for practical use scenarios. This allows the audio cable 103 to hang vertically after the user wears the earphones 100, making it easier to use.

[0047] refer to Figure 4 、 Figure 6 and Figure 7 In some embodiments of the present invention, a second arcuate groove 402 is formed on the outer circumference of the elastic member 201, and the outer diameter of the ends of the elastic member 201 along the thickness direction is larger than the outer diameter of the middle section of the elastic member 201. This design is also intended to enhance the elastic force of the elastic member 201. The second arcuate groove 402 on the outer circumference allows the ends of the elastic member 201 to tilt toward the middle more easily, and provides space for the elastic member 201 to deform, making the elastic member 201 more flexible.

[0048] refer to Figure 5 、 Figure 8 、 Figure 9 and Figure 10In some embodiments of the utility model, the inside of headband 101 is provided with a cavity 501, the rotating shaft 202 is provided with a third through hole 502, and the third through hole 502 communicates the inside of the ear shell 102 with the cavity 501. Such design can make the wires and other components smoothly extend into the ear shell 102 from the cavity 501 inside the headband 101, realize the electrical conduction of the headband 101 and the ear shell 102, and the design of the third through hole 502 can improve the utilization rate of space, so that the components inside the earphone 100 are arranged more reasonably and closely.

[0049] It should be noted that, referring to Figure 2 、 Figure 7 and Figure 9 In some embodiments of the utility model, a relatively wide gap is left after the installation of the two rotating shaft sleeves 204, so that the use of the third through hole 502 is not affected by the installation of the rotating shaft sleeve 204.

[0050] It should be noted that, referring to Figure 10 In some embodiments of the utility model, the earphone 100 further comprises a damping strip 1001, the damping strip 1001 is arranged in the cavity 501, the side surface of the damping strip 1001 towards the center of the cavity 501 is wavy, Figure 1 As shown in the left half of the headband 101, the right half of the headband 101 is still provided with a damping strip 1001, and a stretchable band (not shown in the figure) is arranged at the left and right connecting portions, the stretchable band is slidably arranged in the cavity 501 and the outer surface abuts against the wavy surface of the damping strip 1001, such design can make the left and right headbands 101 contract and expand, so that the earphone 100 has a contraction storage function, and the wavy surface of the damping strip 1001 can prevent the earphone 100 from sliding after expansion, improving the structural stability.

[0051] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled persons in the technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
