[0029] In the prior art, the earmuffs of the headset are connected to the headband 1 through a rotating shaft. Since the rotating shaft has a single degree of freedom, it can only rotate in one direction. After the user wears the headset 100 that can only rotate in one direction, the ear cup 2 and the head or ear cannot be completely fitted. At this time, the pressure of the headband 1 and the ear cup 2 will be concentrated in the fitting area, and the contact area is small, so the pressure in this area is relatively large. Due to the different shapes of the human head and ears, the contact area of ​​the fitting area is also different. After wearing for a long time, different degrees of local pain will occur in this area, and the comfort experience is not good.

[0030] See also Figures 1 to 4 The utility model provides an earphone 100, comprising a headband 1 and an ear cup 2. A connecting shaft 11 is formed on both sides of the headband 1. Each connecting shaft 11 is formed with a spherical groove 111, and the two spherical grooves 111 are arranged opposite to each other. There are two ear cups 2, each ear cup 2 is formed with an annular groove 21 and a mounting shaft 22 arranged at the center of the annular groove 21. A spherical surface is formed at the bottom of the mounting shaft 22. The two mounting shafts 22 are rotatably mounted on the two spherical grooves 111 respectively, and the spherical surfaces are slidably connected to the side walls of the spherical grooves 111. Specifically, the operator rotates and installs the ear cup 2 in the spherical groove 111 through the installation shaft 22, and the spherical surface is slidably connected to the side wall of the spherical groove 111, so that the user can rotate the installation shaft 22 in the spherical groove 111 according to his or her own usage habits and comfort, so that the ear cup 2 can rotate along the X, Y and Z axes, so that the fit and contact area between the earphone 100 and the head and ear are greatly improved, and the adaptability of the earphone 100 is improved. In this way, the pressure felt by the user after wearing it will be significantly reduced, the comfort is significantly improved, and the user's comfort is improved.

[0031] See also Figures 1 to 4In one embodiment, the earphone 100 further includes an elastic member 3, one side of the elastic member 3 abuts against the top of the connecting shaft 11, and the other side of the elastic member 3 abuts against the bottom of the annular groove 21. A certain amount of interference is maintained between the elastic member 3, the ear cup 2 and the connecting shaft 11. When the ear cup 2 rotates along the X and Z axes, the elastic member 3 will be back compressed, and the elastic member 3 will generate a certain restoring force. When the ear cup 2 is rotated, this restoring force will be converted into a damping feeling generated during rotation; when the user wears the earphone 100, the restoring force will also act on the user's head and ears through the ear cup 2, and be converted into pressure on the head and ears; different pressures can be obtained by adjusting the thickness and Shore hardness of the elastic member 3 to meet the comfort requirements of different users.

[0032] In one embodiment, there are multiple elastic members 3, and the multiple elastic members 3 are arranged in a circle along the central axis of the spherical groove 111. By providing multiple elastic members 3, the force between the ear cup 2 and the connecting shaft 11 can be more uniform. When the ear cup 2 acts on the user's head and ears, the user's head and ears are subjected to more uniform force, further improving the user's comfort.

[0033] In one embodiment, the earphone 100 further includes an annular elastic member 3, the mounting shaft 22 passes through the annular elastic member 3 and is rotatably mounted in the spherical groove 111, one side of the annular elastic member 3 abuts against the top of the connecting shaft 11, and the other side of the annular elastic member 3 abuts against the bottom of the annular groove 21. The elastic member 3 is set in an annular shape, so that only one elastic member 3 is needed to make the force between the ear cup 2 and the connecting shaft 11 uniform, so that when the ear cup 2 acts on the user's head and ears, the user's head and ears will also be uniformly stressed, reducing the difficulty of installing the earphone 100 and simplifying the installation steps.

[0034] In one embodiment, the spherical groove 111 is formed with a boss 112, the mounting shaft 22 is formed with a first through hole 221, the diameter of the boss 112 is smaller than the diameter of the first through hole 221, and the boss 112 extends into the first through hole 221. When the ear cup 2 rotates around the X-axis and the Z-axis, when the boss 112 abuts against the hole wall of the first through hole 221, the ear cup 2 is blocked from continuing to rotate around the X-axis and the Z-axis, thereby preventing the mounting shaft 22 from being separated from the spherical groove 111.

[0035] In one embodiment, the inner wall of the first through hole 221 is a spherical surface, and the earphone 100 further includes a ball joint 4, which is formed with a second through hole 41. The ball joint 4 is sleeved on the boss 112 through the second through hole 41, and the outer surface of the ball joint 4 is slidably connected to the inner wall of the first through hole 221. By providing the ball joint 4, when the ear cup 2 rotates, the inner and outer sides of the mounting shaft 22 are slidably connected to the spherical groove 111 and the ball joint 4 respectively, which can improve the efficiency of rotation and avoid the occurrence of a jamming feeling during rotation. In addition, the size relationship between the outer diameter of the spherical surface of the mounting shaft 22, the inner diameter of the spherical groove 111 and the outer diameter of the ball joint 4 is respectively: the outer diameter of the ball joint 4 is less than or equal to the outer diameter of the spherical surface of the mounting shaft 22, and the outer diameter of the spherical surface of the mounting shaft 22 is less than or equal to the outer diameter of the spherical surface of the mounting shaft 22. In fact, because the spherical space formed by the hemispherical features of the ball joint 4 and the spherical groove 111 is three-dimensional, the ear cup 2 can not only rotate in the positive directions of the X, Y and Z axes, but also rotate freely in the formed three-dimensional spherical space.

[0036] In one embodiment, the ball joint 4 is formed with a protrusion 42, the mounting shaft 22 is formed with a notch 222 interconnected with the first through hole 221, and the protrusion 42 is installed in the notch 222. By providing the protrusion 42, the ball joint 4 can be prevented from moving in the first through hole 221, ensuring that the earphone 100 can rotate normally for a long time.

[0037] In one embodiment, there are multiple notches 222 and multiple protrusions 42, and the number of the multiple notches 222 is equal to the number of the multiple protrusions 42, and they are arranged one by one. By providing multiple protrusions 42, the ball joint 4 can be further prevented from moving in the first through hole 221, and the earphone 100 can be further ensured to rotate normally for a long time.

[0038] In one embodiment, the boss 112 is formed with a third through hole 112a, and the earphone 100 further includes a fastener 5, which includes a first connecting section 51 and a second connecting section 52 connected to each other, the first connecting section 51 is installed in the third through hole 112a, and the second connecting section 52 is in contact with the ball joint 4. By providing the fastener 5, the ball joint 4 can be prevented from being separated from the first through hole 221, thereby reducing the probability of repairing the earphone 100 and greatly increasing the service life of the earphone 100.

[0039] In one embodiment, the center of the ball joint 4 is located at the same position as the center of the spherical groove 111. After the ball joint 4 and the spherical groove 111 are assembled, the centers of the two components are ensured to be located at the same position, that is, the two centers coincide, so that the rotation range can be expanded as much as possible.

[0040] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
