[0015] According to some embodiments of the present invention, the first part includes a main body part and an abutting part connected to each other. The main body part covers the headband and is disposed in the movable channel. The abutting part is disposed around the outer wall of the main body part and abuts against the end of the tube body facing the headband.

[0016] According to some embodiments of the present invention, the adjustment assembly further includes a cover, which is connected to the end of the tube facing the headband and closes the opening. The interior of the cover defines a receiving cavity, which communicates with the movable channel, and the headband passes through the receiving cavity.

[0040] The adjustment assembly 100 of the first aspect embodiment and the headphone 10 of the second aspect embodiment of the present invention will now be described with reference to the accompanying drawings.

[0041] The first aspect of this utility model provides an adjustment component 100 for adjusting headphones, see below. Figures 1 to 4 As shown, the adjustment assembly 100 includes a tube 110, a headband 120, a damping element 130, and a limiting element 140. The tube 110 has an internal movable channel 111, which connects to an opening 1111 on one side of the tube 110. The headband 120 enters the movable channel 111 through the opening 1111 and is movably positioned within it. The damping element 130 is located within the movable channel 111 and connects the tube 110 and the headband 120. Specifically, the damping element 130 is located between the headband 120 and the inner wall of the movable channel 111. The damping element 130 provides resistance to the headband 120 to help fix its position and prevent it from slipping out of the movable channel 111 under gravity. The limiting member 140 is fixedly installed in the movable channel 111 and connected to the damping member 130 on the side opposite to the opening 1111. The limiting member 140 is provided with a through hole 1411, so that the headband 120 can move through this through hole 1411.

[0042] Specifically, when the headband 120 moves relative to the tube body 110, it passes through the through hole 1411 of the damping member 130 and the limiting member 140, thereby adjusting the headphones 10. During the movement of the headband 120, friction is generated between the damping member 130 and the headband 120, causing the damping member 130 to move along with the headband 120. However, when the damping member 130 contacts the limiting member 140, because the volume of the damping member 130 is larger than the size of the through hole 1411, the limiting member 140 impedes the movement of the damping member 130, restricting its movement along with the headband 120, thus preventing excessive friction and wear between the damping member 130 and the inner wall of the tube body 110. At the same time, the through hole 1411 on the limiting member 140 also ensures that the movement restriction of the headband 120 is minimized, ensuring that the headband 120 can be smoothly adjusted in position.

[0043] In related technologies, when adjusting the headphones 10, the damping element 130 moves along with the headband 120. After a period of use, the damping element 130 will wear due to friction with the inner wall of the tube 110, causing the connection between the damping element 130 and the inner wall of the tube 110 to loosen, affecting the use of the headphones 10.

[0044] The adjustment assembly 100 of this embodiment of the invention, by positioning the limiting member 140 on the side of the damping member 130 opposite to the opening 1111, ensures that when the headband 120 moves relative to the tube body 110, the damping member 130 will not move along with the headband 120 due to the frictional force between itself and the headband 120. This reduces frictional wear between the damping member 130 and the inner wall of the tube body 110 during the movement of the headband 120. Furthermore, a through hole 1411 is provided on the limiting member 140, allowing the headband 120 to pass through the through hole 1411 during movement, thus preventing the limiting member 140 from affecting the adjustment of the headband 120.

[0045] In some embodiments, see Figures 3 to 5As shown, the tube body 110 also includes a blocking part 112. The blocking part 112 is disposed within the movable channel 111 and extends towards the central axis of the tube body 110. The blocking part 112 is connected to the side of the limiting member 140 opposite to the damping member 130. Specifically, the tube body 110 is a tubular structure with a central axis. The blocking part 112 is connected to the inner wall of the movable channel 111 and extends towards the central axis. When the limiting member 140 is disposed on the inner wall of the movable channel 111, the limiting member 140 will connect with the blocking part 112. The blocking part 112 will hinder the movement of the limiting member 140, preventing the limiting member 140 from shifting or loosening when subjected to external force, thereby affecting the performance of the adjusting assembly 100. Thus, during the adjustment of the headband 120, the blocking part 112 can not only ensure that the damping member 130 does not move with the headband 120, but also ensure that the limiting member 140 remains stable, improving the adjustment effect of the adjusting assembly 100.

[0046] In some embodiments, to improve the functionality of the blocking portion 112, the surface of the blocking portion 112 is provided with protrusions or textures, thereby increasing the friction between the blocking portion 112 and the limiting member 140, and further enhancing the stability of the limiting member 140. Furthermore, in another embodiment, the blocking portion 112 and the inner wall of the tube body 110 are detachable, allowing the user to replace the blocking portion 112 with different shapes or sizes according to actual needs, to meet the requirements of different sized limiting members 140.

[0047] Furthermore, in some embodiments, see [reference] Figures 1 to 5 As shown, the limiting member 140 includes a limiting portion 141 and a protrusion 142. A through hole 1411 is provided on the limiting portion 141, and the limiting portion 141 is connected to the blocking portion 112, thereby ensuring the stability of the limiting member 140. In addition, a groove 113 is defined inside the tube body 110, which communicates with the movable channel 111 and is located between the opening 1111 and the blocking portion 112. The protrusion 142 is designed to match the groove 113, so that the protrusion 142 can be accommodated in the groove 113.

[0048] Specifically, when the limiting member 140 enters the movable channel 111 through the opening 1111 of the tube body 110 for assembly, the limiting portion 141 of the limiting member 140 abuts against the inner wall of the movable channel 111, while the protrusion 142 is accommodated in the sliding groove 113 for sliding, allowing the limiting member 140 to enter the movable channel 111 for assembly along the path of the sliding groove 113. The abutment between the limiting portion 141 and the inner wall of the movable channel 111 generates friction, which restricts the limiting portion 141, preventing axial movement of the limiting member 140 relative to the tube body 110. The sliding groove 113 restricts the circumferential movement of the limiting member 140, preventing rotation of the limiting member 140 relative to the tube body 110. The limiting member 140 can not only effectively prevent the damping member 130 from moving with the headband 120, but also increase the overall stability of the limiting member 140 through the cooperation of the protrusion 142 and the slide groove 113, preventing the limiting member 140 from shifting or loosening during use.

[0049] In some embodiments, see Figures 1 to 6 As shown, the blocking part 112 is disposed around the inner wall of the movable channel 111, and the interior of the blocking part 112 defines a movable hole 1121 along the movable direction of the headband 120. The movable hole 1121 corresponds to the through hole 1411 on the limiting member 140, allowing the headband 120 to pass through both for position adjustment.

[0050] Specifically, the blocking part 112 is inclined relative to the limiting member 140, forming a certain angle between the blocking part 112 and the limiting member 140. Specifically, when the headband 120 passes through the movable hole 1121, the headband 120 will contact the blocking part 112 on the side facing the central axis of the tube body 110. Friction will be generated between the blocking part 112 and the headband 120, causing the blocking part 112 to tend to bend along the direction of movement of the headband 120. In this embodiment, by inclining the blocking part 112 relative to the limiting member 140, the bending deformation of the blocking part 112 under the action of friction can be reduced when the blocking part 112 contacts the headband 120. Furthermore, by tilting the blocking part 112 relative to the limiting member 140, the contact area between the headband 120 and the blocking part 112 can be increased. This helps to maintain the headband 120 in the selected position after the headband 120 has been adjusted, thus preventing the headband 120 from moving relative to the tube body 110 on its own.

[0051] In some embodiments, the blocking portion 112 is made of an elastic material. Using an elastic material for the blocking portion 112 not only enhances the fixing strength of the headband 120 but also effectively absorbs vibration and impact, reducing the impact on internal components. Specifically, since the blocking portion 112 is made of an elastic material, the movable hole 1121 formed by the blocking portion 112 can be varied according to actual use. When the headband 120 passes through the movable hole 1121, the blocking portion 112 can deform to always abut against the outer wall of the headband 120. When the headband 120 is adjusted to a designated position, the abutment between the blocking portion 112 and the outer wall of the headband 120 further maintains the position of the headband 120, preventing the headband 120 from moving relative to the tube body 110. Furthermore, when the user quickly adjusts the position of the headband 120 or the headphones are accidentally impacted, the elastic material blocking portion 112 can act as a buffer, protecting the internal structure from damage. In this embodiment, the elastic material is made of materials such as rubber or silicone. In other embodiments, the elastic material can also be a highly elastic engineering plastic.

[0052] In some embodiments, see Figures 2 to 9 As shown, the adjustment assembly 100 also includes a fixing member 150, which is connected to the tube body 110 and disposed in the movable channel 111. The fixing member 150 is used to connect the headband 120 to prevent the headband 120 from contacting the inner wall of the tube body 110. The fixing member 150 defines a receiving cavity 151 inside. When the headband 120 is connected to the tube body 110, the headband 120 is also received in the receiving cavity 151, thereby achieving the covering of the headband 120 by the fixing member 150, thereby preventing the headband 120 from contacting the inner wall of the tube body 110.

[0053] Specifically, the headband 120 is configured to move within the movement channel 111 to adjust the wearing length of the headphones 10. When the headband 120 moves, it moves the fixing member 150 along with it, ensuring that the fixing member 150 remains between the headband 120 and the inner wall of the tube 110. This prevents friction between the headband 120 and the inner wall of the tube 110, thus avoiding wear and reducing the service life of the headband 120. When the fixing member 150 moves to the position of the limiting member 140, it also passes through the through hole 1411 along with the headband 120.

[0054] Furthermore, in some embodiments, see [reference] Figures 2 to 9As shown, the fastener 150 includes a first part 152 and a second part 153, which are separated from each other. A damping element 130 is disposed between the first part 152 and the second part 153. The first part 152 is connected to the end of the tube 110 facing the headband 120, i.e., the first part 152 is located at the opening 1111 of the tube 110. The second part 153 is disposed in the movable channel 111 to connect to the headband 120. Both the first part 152 and the second part 153 have a receiving cavity 151 inside. The first part 152 covers the headband 120 located at the opening 1111 of the movable channel 111. The second part 153 covers the end of the headband 120.

[0055] Specifically, the movable channel 111 forms an opening 1111 at the end of the tube 110, allowing the headband 120 to enter the movable channel 111. The first part 152 is connected to the end of the tube 110 to cover the headband 120 at the end of the tube 110. When the headband 120 moves relative to the tube 110, the headband 120 moves within the receiving cavity 151 of the first part 152. The first part 152 does not move with the headband 120, while the second part 153 moves with the headband 120 and passes through the through hole 1411 of the limiting member 140. By separating the first part 152 and the second part 153, the fixing member 150 can support the headband 120 at two locations, so that the headband 120 is suspended relative to the interior of the tube 110 (i.e., the fixing member 150 does not contact the inner wall of the tube 110). Furthermore, as the length of the headband 120 entering the active channel 111 increases, the headband 120 tends to bend, and the end of the headband 120 bends before the middle part. Therefore, by placing the first part 152 at the end of the tube body 110 and the second part 153 connecting to the end of the headband 120, the headband 120 can be better supported, reducing the possibility of contact between the headband 120 and the tube body 110.

[0056] Furthermore, in some embodiments, see [reference] Figures 7 to 9As shown, the first part 152 includes a main body part 1521 and an abutment part 1522 connected to each other. The main body part 1521 is disposed in the movable channel 111 and covers the outside of the headband 120. By accommodating the main body part 1521 in the movable channel 111 to cover the headband 120, contact friction between the headband 120 and the inner wall of the tube body 110 can be avoided. Furthermore, the abutment part 1522 is circumferentially disposed on the outer wall of the main body part 1521 and is located on the outer side of the movable channel 111, abutting against the end of the tube body 110 facing the headband 120. By surrounding the outer wall of the main body part 1521, the circumferential area of ​​the abutment part 1522 is larger than the circumferential area of ​​the main body part 1521 and the circumferential area of ​​the tube body 110. When the first part 152 is connected to the tube body 110, the abutting part 1522 is blocked outside the movable channel 111, so that the abutting part 1522 and the end of the tube body 110 abut against each other. When the headband 120 moves relative to the first part 152, the abutting part 1522 can prevent the first part 152 from moving with the headband 120 and entering the movable channel 111. This allows the first part 152 to always cover the headband 120 at the end of the tube body 110, preventing friction between the headband 120 and the inner wall of the tube body 110.

[0057] In some embodiments, see Figures 1 to 9 As shown, the adjustment assembly 100 also includes a cover 160. The cover 160 is connected to the end of the tube 110 facing the headband 120 to close the opening 1111 of the tube 110 and prevent other parts from falling out of the opening 1111. The interior of the cover 160 defines a receiving cavity 161, and the movable channel 111 communicates with the receiving cavity 161. A portion of the headband 120 passes through the receiving cavity 161.

[0058] Specifically, a portion of the fastener 150 is located outside the movable channel 111, within the receiving cavity 161 of the cover 160, while the remaining portion extends into the movable channel 111. This allows the fastener 150 to provide necessary support and stability to the headband 120 without interfering with its movement. The cover 160 not only protects the fastener 150 but also limits its position, preventing it from shifting relative to the tube 110 due to friction with the headband 120 during movement. This ensures smooth and reliable operation of the adjusting assembly 100. Furthermore, by accommodating a portion of the fastener 150 within the receiving cavity 161 of the cover 160, the adjusting assembly 100 becomes more compact and stable. Furthermore, since the fastener 150 can be effectively positioned, the fastener 150 can operate the headband 120 more precisely, thereby improving the user experience.

[0059] A second aspect of this utility model provides a headset 10, see reference. Figures 1 to 10 As shown, the headset 10 includes the adjustment assembly 100 and the headphone unit 200 described in any of the above embodiments. The headphone unit 200 is connected to the end of the tube 110 away from the headband 120.

[0060] Specifically, the headband 120 is configured to move within the movable channel 111, allowing it to enter and exit the channel, thereby changing its telescopic length. When the headband 120 moves, the presence of the damping element 130 ensures it remains stably in the selected position after adjustment, maintaining its length. During the movement of the headband 120, the limiting element 140 prevents the damping element 130 from moving with the headband 120 due to friction, reducing wear between the damping element 130 and the inner wall of the tube 110 and extending the product's lifespan. The earphone unit 200 is fixed to the end of the tube 110 by connecting components (e.g., screws or clips), ensuring a stable connection between the earphone unit 200 and the tube 110.

[0061] The headset 10 of this embodiment of the invention allows the headband 120 to move relative to the tube 110 within the movable channel 111, thereby changing the distance between the headband 120 and the headphone unit 200. This adapts the headset 10 to different head shapes and improves the wearing comfort of the headset 10. Furthermore, the limiting member 140 limits the damping member 130, restricting its movement and reducing friction and wear between the damping member 130 and the tube 110, thus extending the service life of the damping member 130.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
