DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the present application more clear, specific embodiments and the drawings will be further described in detail, the schematic embodiment of the present application and its description are only used to explain the present application, and not as the limitation of the present application.

[0030] Embodiment:

[0031] As shown in Figures 1-5 , the present embodiment relates to a headset, which comprises a headband 1, both ends of the headband 1 are provided with an interpolation bar 2, one end of the interpolation bar 2 is connected with the headband 1 and can be freely expanded and contracted at the end of the headband 1, the other end of the interpolation bar 2 is connected with an earphone unit 4, a knuckle 3 is arranged between the earphone unit 4 and the interpolation bar 2, the earphone unit 4 is rotationally connected with the knuckle 3, and the knuckle 3 is embedded in the interpolation bar 2.

[0032] At present, in the field of Bluetooth earphone headsets, the two earphone units 4 on both sides are effectively pressed against the user's head through the connection of the headband 1, so that they can be effectively worn. Due to the differences in head shape of different users, the tightness adjustment of the headband 1 can effectively adapt to the use requirements of different users. However, the headsets in the prior art are usually fixed in structure and can only adjust the tightness of the headband 1, and cannot adjust the orientation of the earphone unit 4, so when used by different users, the headset often needs to be adjusted to an excessively compressed state to ensure the sound receiving effect.

[0033] In this embodiment, the extension length between the inner plug bar 2 and the headband 1 can be freely adjusted, and the extension adjustment between the inner plug bar 2 and the headband 1 at both ends of the headband 1 is independent of each other, thereby improving the adaptability of the wearing adjustment of this embodiment. The inner plug bar 2 and the earphone unit 4 are provided with a universal joint 3, which is used to provide a rotation adjustment space for the earphone unit 4, so that the earphone unit 4 can rotate relative to the inner plug bar 2, thereby allowing the contact position of the earphone unit 4 with the user to be adjusted to a certain extent. In this embodiment, the rotation angle of the earphone unit 4 is limited by the rotation space between the universal joint 3 and the earphone unit 4, so that the earphone unit 4 can be adjusted within a certain angle range, and the angle difference of the earphone unit 4 when worn by different users is small, so the required rotation angle of the earphone unit 4 is also small, thereby making it unnecessary to make large-angle adjustment in the specific implementation of this embodiment, and the rotation space provided by the universal joint 3 is sufficient to accommodate the required adjustment angle of the earphone unit 4.

[0034] Further, the headband 1 includes a solid section 11, both ends of the solid section 11 are provided with an end housing 13, and an end cavity 12 is arranged in the end housing 13.

[0035] The end of the solid section 11 is also provided with an inner plug groove 14 for accommodating the plug-in of the inner plug bar 2.

[0036] In this embodiment, the solid section 11 is used to constrain the position of the headband 1, the end cavity 12 in the end housing 13 is used to accommodate the insertion of the inner plug bar 2, and since the inner plug bar 2 is plugged into the inner plug groove 14, the inner plug bar 2 is not constrained when it is inserted into the end housing 13, but is constrained when it is inserted into the solid section 11.

[0037] The inner plug bar 2 needs to press the earphone unit 4 against the user's head, so the inner plug bar 2 will be subjected to an outward bending force. In this embodiment, there is a socket on the end housing 13 when the inner plug bar 2 is inserted into the end housing 13, and there is a gap between the socket and the inner plug bar 2. When the inner plug bar 2 is inserted into the solid section 11, it is in contact with the inner plug groove 14.

[0038] Therefore, when the inner insertion bar 2 is subjected to external force, the inner insertion groove 14 can effectively limit the end of the inner insertion bar 2, and the end shell 13 and the end cavity 12 can allow the inner insertion bar 2 to be slightly bent, thereby avoiding damage to the inner insertion bar 2 caused by excessive shear stress. The embodiment fully utilizes the flexibility of the inner insertion bar 2 on the basis of ensuring the adjustment effect, thereby ensuring the safety of the use of the inner insertion bar 2.

[0039] Further, the inner insertion bar 2 comprises an insertion section 21 and an anti-torsion section 22, the upper end of the anti-torsion section 22 is connected with the insertion section 21 and is bent and extended away from one side of the earphone unit 4, and the knuckle 3 is embedded in the lower end of the anti-torsion section 22.

[0040] The insertion section 21 is used to adjust the length of the inner insertion bar 2 inserted into the headband 1, and the inner insertion bar 2 has a certain flexibility, so as to facilitate the earphone unit 4 to fit the human body. However, only relying on the flexibility of the insertion section 21 will result in poor adaptability of the inner insertion bar 2 when controlling the earphone unit 4 to fit the human body. According to the shape of most people's heads, if the top of the headband 1 and the earphone unit 4 need to be considered for fitting, the length of the headband 1 needs to be increased, thereby avoiding the risk that the user cannot wear the whole headset, and the user experience is poor.

[0041] In the embodiment, the inner insertion bar 2 is provided in sections by the insertion section 21 and the anti-torsion section 22, so that the earphone unit 4 applies force more through the anti-torsion section 22, the upper end of the anti-torsion section 22 is connected with the insertion section 21 and is bent and extended away from one side of the earphone unit 4, thereby increasing the distance between the two earphone units 4 of the headset by using the extension length of the anti-torsion section 22, so that the overall length of the headband 1 can be reduced, and the headband 1 can fit the user's head more closely. The bending part applies a torsional moment to the earphone unit 4, so that the earphone unit 4 can be fitted on the human body, thereby making the embodiment more in line with the ergonomic design.

[0042] Further, the side of the anti-torsion section 22 away from the earphone unit 4 is provided with an inner groove, and a reinforcing sheet 23 is embedded in the inner groove.

[0043] Since it is necessary to enhance the stability of the earphone unit 4 during use, the embodiment improves the rigidity of the lower half of the anti-torsion section 22 by providing an inner groove on the anti-torsion section 22 and embedding a reinforcing sheet 23, so that the inner insertion bar 2 can remain stable enough during use of the earphone unit 4, and the inner insertion bar 2 will not be twisted or the like when the user turns his head or the like, thereby avoiding the problem of unstable use.

[0044] Further, one side of the insertion section 21 towards the earphone unit 4 is provided with a guide groove 24, which extends to the end of the insertion section 21.

[0045] The inner insertion groove 14 is provided with a guide rib, which can be embedded in the guide groove 24.

[0046] In this embodiment, the insertion section 21 is provided with a guide groove 24, and the inner insertion groove 14 is provided with a guide rib matched with the guide groove 24, so as to enhance the limiting effect of the inner insertion groove 14 on the insertion section 21, so that the insertion section 21 can only slide in the direction limited by the guide rib on the inner insertion groove 14, thereby enhancing the controllability of the inner insertion strip 2 on the inner insertion groove 14.

[0047] In the actual application of this embodiment, the adjustment range that can be adapted by the earphone unit 4 can be effectively controlled through the extension and retraction of the inner insertion strip 2 in the inner insertion groove 14. The position of the inner insertion strip 2 in the inner insertion groove 14 is limited by friction. During the use of the earphone, the earphone unit 4 is pressed against the human body, and the inner insertion strip 2 will be subjected to a force acting outwardly from the human body. At this time, the extrusion between the insertion section 21 of the inner insertion strip 2 and the inner insertion groove 14 will be enhanced, the friction between the inner insertion strip 2 and the inner insertion groove 14 will be enhanced, the friction area will be increased under the action of the guide groove 24 and the guide rib, and thus the friction will be further increased. Therefore, the stability of the inner insertion strip 2 in the inner insertion groove 14 can be ensured during wearing.

[0048] Further, the knuckle 3 comprises a first embedded end 31, the first embedded end 31 is connected with a steering sleeve 32, the steering sleeve 32 is nested with a damping member 35, and the damping member 35 is fixedly connected with a connecting end 33.

[0049] The first embedded end 31 is embedded in the inner insertion strip 2, and the connecting end 33 is embedded in the earphone unit 4.

[0050] The damping member 35 can rotate in the steering sleeve 32, and there is damping between the damping member 35 and the steering sleeve 32.

[0051] In this embodiment, the first embedded end 31 is used to fix the position of the knuckle 3 on the inner insertion strip 2, the steering sleeve 32 is used to accommodate the damping member 35, the chain section is used to connect the damping member 35 and the earphone unit 4, the damping member 35 rotates in the steering sleeve 32 and can extrude the steering sleeve 32, so as to change the relative angle between the earphone unit 4 and the inner insertion strip 2, so as to achieve the purpose of adjusting the angle of the earphone unit 4.

[0052] The damping member 35 is made of elastic material, and the surface of the damping member 35 can form a large friction force. Through the rotation of the damping member 35 in the steering sleeve 32, the earphone unit 4 can be driven to rotate. When the damping member 35 is extruded by the inner wall of the steering sleeve 32, the damping force is generated through the friction force and the elastic force, so as to avoid the problem that the earphone unit 4 is too flexible to rotate and causes the earphone to leak sound.

[0053] In the embodiment, the damping of the damping member 35 can keep the earphone unit 4 fit the head of the user when the angle of the earphone unit 4 is adjusted, so as to guarantee the sound effect of the earphone unit 4. The damping member 35 can be made of rubber.

[0054] Further, the outer sleeve shell 36 is further provided, the steering sleeve 32 and the connecting end 33 are partially sleeved in the outer sleeve shell 36, and gaps are left between the outer sleeve shell 36 and the inner insertion strip 2 and between the outer sleeve shell 36 and the earphone unit 4.

[0055] In the embodiment, the outer sleeve shell 36 is used for protecting the steering sleeve 32 and the connecting end 33. The gaps left between the outer sleeve shell 36 and the inner insertion strip 2 and between the outer sleeve shell 36 and the earphone unit 4 can make the rotation of the earphone unit 4 have enough rotation space, and the relative position of the connecting end 33 and the steering sleeve 32 is limited by the outer sleeve shell 36, so that the rotation space can only be realized through the rotation and / or deformation of the damping member 35.

[0056] Further, the connecting end 33 is provided with a center hole 34, and the connecting end 33 is embedded in one side of the earphone unit 4 and provided with an extension section 37. The extension section 37 is hollow, and the center hole 34 is in communication with the inside of the extension section 37.

[0057] The extension section 37 is detachably and fixedly connected with the connecting end 33.

[0058] In the embodiment, the connecting end 33 is connected with the extension section 37, and the extension section 37 extending into the earphone unit 4 can enhance the connection stability of the connecting end 33 and the earphone unit 4. The center hole 34 on the connecting end 33 can effectively accommodate the air flow generated when the damping member 35 rotates or deforms, so as to avoid the damping member 35 being affected by the air pressure.

[0059] In the embodiment, the earphone unit 4, the inner insertion strip 2 and the sound generation and circuit connection in the headband 1 all adopt the models that can be mass configured in the prior art, so that the embodiment can be mass produced.

[0060] The above specific embodiments explain the purpose, technical scheme and beneficial effects of the present application in further detail. It should be understood that the above description is only a specific embodiment of the present application and is not intended to limit the scope of protection of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
