[0002] The Chinese utility model patent with publication number CN115022764A provides a smooth damping telescopic structure for headphones and headphones, which includes two left and right headphone components and a smooth damping telescopic structure for headphones located between the two headphone components, the smooth damping telescopic structure includes a head-mounted connector and an assembly slide arm, the head-mounted connector includes a hollow connector body, the assembly slide arm includes a columnar slide arm body, the top of the slide arm body is sleeved with an upper damping ring on the outer side, and the top of the slide arm body is slidably connected to the inner wall of the connector body through the upper damping ring, the bottom of the connector body is sleeved with a lower damping ring on the inner side, and the outer side wall of the slide arm body is slidably connected to the inner side of the bottom of the connector body through the lower damping ring. The present invention realizes the sliding connection between the assembly slide arm and the head-mounted connector, and increases the damping effect between the two. Not only can the assembly slide arm be adjusted and positioned at any position to adapt to the head shape and wearing of different users, but also the comfort of adjustment can be increased by increasing the damping sliding.

[0003] The headband of the headset of this prior art adopts a damping telescopic structure, which mainly relies on two annular silicone damping rings at the upper and lower ends to achieve a damping feeling, and the slide arm slider is sleeved in the inner groove of the connector through the inner wall of the connector body that corresponds to the slide arm slider, so as to achieve sliding. However, the problems are that, on the one hand, the annular silicone damping rings set at the upper and lower places will cause the damping force to be too large, and the telescopic control is difficult; secondly, the guide sliding groove is a single groove structure, which causes shaking during the telescopic sliding process and unstable sliding. Utility Model Content

[0004] The purpose of the utility model is to provide a pull-out damping telescopic structure, an earphone headset and a head-mounted earphone, aiming to solve the technical problems in the prior art of using a damping ring to realize the head-mounted telescopic structure of the earphone, such as difficulty in telescopic control caused by excessive damping force and unstable telescopic sliding.

[0005] To achieve the above object, an embodiment of the present utility model provides a pull-damping telescopic structure, which includes a sliding arm, a lower cover of the sliding arm, and an upper cover of the sliding arm. The upper cover of the sliding arm is covered on the lower cover of the sliding arm and fixedly connected to the lower cover of the sliding arm. A telescopic channel for accommodating the sliding arm is formed between the upper cover of the sliding arm and the lower cover of the sliding arm.

The sliding arm is accommodated in the telescopic channel. A damping mounting seat is arranged at the inner end of the sliding arm. Damping blocks are respectively installed on two opposite sides of the damping mounting seat. The two damping blocks are respectively slidably connected to the two side sliding grooves in a matching manner.

[0006] Optionally, the lower cover of the sliding arm and the upper cover of the sliding arm are respectively provided with a protection gasket with corresponding positions. The surfaces of the two protection gaskets facing the sliding arm form a special-shaped surface adapted to the surface shape of the sliding arm.

[0007] Further, a gap is formed between the special-shaped surface and the surface of the sliding arm.

[0008] Optionally, the connection line between the two protection gaskets and the connection line between the two damping blocks form a perpendicular intersection in space.

[0015] One or more of the above technical solutions provided by the embodiments of the present utility model for the pull-damping telescopic structure, headphone headband, and headphone have at least one of the following technical effects: In the present utility model, the sliding arm is arranged in the telescopic channel formed by the lower cover of the sliding arm and the upper cover of the sliding arm. The outer end of the sliding arm extends out of the telescopic channel. Two damping blocks are arranged on the damping mounting seat at the inner end of the sliding arm and are respectively adapted to the side sliding grooves on both sides of the lower cover of the sliding arm. When pulling the outer end of the sliding arm, the two damping blocks slide in the two side sliding grooves respectively. Due to the damping effect generated by the damping blocks, a damping feeling will be generated when pushing and pulling the sliding arm, but it will not, like in the traditional technology, have an excessive damping force that affects the use experience. At the same time, the two damping blocks also act as guiding blocks and are restricted in the side sliding grooves at both sides, ensuring that the sliding arm will not be unbalanced on both sides during the telescopic process and ensuring better sliding stability.

[0032] In the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0033] In one embodiment of the present utility model, asFigure 1 , 3 As shown in FIGS. 5, 6, and 7, a draw damping telescopic structure is provided and applied to the head of a head-mounted headphone. Specifically, the draw damping telescopic structure includes a sliding arm 10, a lower sliding arm cover 20, and an upper sliding arm cover 30. The upper sliding arm cover 30 covers the lower sliding arm cover 20 and is fixedly connected to the lower sliding arm cover 20. An expansion channel 101 for accommodating the sliding arm 10 is formed between the upper sliding arm cover 30 and the lower sliding arm cover 20. Opposite side walls of the lower sliding arm cover 20 located within the expansion channel 101 are respectively provided with side sliding grooves 102 having the same extending direction as the expansion channel 101. The sliding arm 10 is accommodated within the expansion channel 101. A damping mounting seat 40 is provided at the inner end of the sliding arm 10. Damping blocks 50 are respectively mounted on opposite sides of the damping mounting seat 40. The two damping blocks 50 are respectively adapted to be slidably connected within the two side sliding grooves 102.

[0034] In the draw damping telescopic structure provided by the embodiment of the present utility model, the sliding arm 10 is disposed within the expansion channel 101 formed by the lower sliding arm cover 20 and the upper sliding arm cover 30. The outer end of the sliding arm 10 extends outside the expansion channel 101. Two damping blocks 50 are respectively disposed on opposite sides of the damping mounting seat 40 provided at the inner end of the sliding arm 10 and are respectively adapted to be within the side sliding grooves 102 on both sides of the lower sliding arm cover 20. When pulling the outer end of the sliding arm 10, the two damping blocks 50 respectively slide in a guiding manner within the two side sliding grooves 102. Due to the damping effect generated by the damping blocks 50, a damping feeling will be generated when pushing and pulling the sliding arm 10, but the damping force will not be too large as in the traditional technology to affect the use experience. At the same time, the two damping blocks 50 also act as guiding blocks and are restricted within the side sliding grooves 102 at both sides, ensuring that the sliding arm 10 will not be unbalanced on both sides during the telescopic process and ensuring better sliding stability.

[0035] In an embodiment of the present utility model, as shown in Figure 2 , 4 ~6, the lower sliding arm cover 20 and the upper sliding arm cover 30 are respectively provided with a protective gasket 60 with corresponding positions. The surfaces of the two protective gaskets 60 facing the sliding arm 10 form a special-shaped surface adapted to the surface shape of the sliding arm 10. Specifically, the setting of the protective gasket 60 is used to limit the position of the sliding arm 10 at other positions different from the damping blocks 50.

[0036] Further, a gap is formed between the special-shaped surface and the surface of the sliding arm 10. The special-shaped surface provided on the protective gasket 60 has the same surface shape as the corresponding position of the sliding arm 10 and maintains a sufficient sliding gap, which can prevent the sliding arm 10 from shaking and does not affect the normal sliding of the sliding arm 10. In addition, under a certain applied pressure, even if the sliding arm 10 contacts the protective gasket 60, it will not cause damage to the sliding arm 10, and the structural design has strong practicability.

[0037] Of course, in other embodiments, the protective gasket 60 can be in direct contact with the sliding arm 10.

[0038] In an embodiment of the present invention, as Figures 3 to 4 shown, the connection line between the two protective gaskets 60 and the connection line between the two damping blocks 50 form a perpendicular intersection in space. In this way, the two protective gaskets 60 and the two damping blocks 50 limit the sliding arm 10 in four directions in space, ensuring that the sliding arm 10 is more stable during the telescopic process, avoiding shaking and affecting the use experience.

[0039] Specifically, the state where the connection line between the two protective gaskets 60 and the connection line between the two damping blocks 50 form a perpendicular intersection in space is based on the state after the pull-damping telescopic structure is worn on the user's head. The two protective gaskets 60 are respectively distributed on the left and right sides, and the two damping blocks 50 are respectively distributed on the front and back sides. In this way, when the user wearing the present invention adjusts the telescopic length, the sliding arm 10 will not shake unbalancedly in the left-right and front-back directions, and the use experience is very good.

[0040] Preferably, the damping block 50 is made of silica gel material. The damping block 50 made of silica gel has good damping effect and does not affect the sliding in the side chute 102.

[0041] In an embodiment of the present invention, as Figures 4 to 6 shown, an assembly block 103 for fitting and connecting the sliding arm lower cover 20 and the sliding arm upper cover 30 is provided between the sliding arm lower cover 20 and the sliding arm upper cover 30. Specifically, through the mutual cooperation of the assembly blocks 103, the sliding arm lower cover 20 and the sliding arm upper cover 30 can be detachably assembled and connected, which is convenient for assembly.

[0042] In an embodiment of the present invention, as Figures 4 to 5 shown, the sliding arm lower cover 20 and the sliding arm upper cover 30 are further locked and connected by fastening screws 104. Further, the fastening member can stably lock the sliding arm upper cover 30 and the sliding arm lower cover 20 to ensure that they will not become loose under the action of general external forces.

[0043] The embodiment of the present invention also provides a headphone headband, asFigure 1 As shown, the headband of the earphone includes the above-mentioned draw damping telescopic structure. The headband of the earphone in this embodiment uses the above-mentioned draw damping telescopic structure, which generates a damping feeling during specific use, and the user experience is better.

[0044] The embodiment of the present invention also provides a headphone, which includes the above-mentioned headband of the earphone. Since the headband of the earphone in this embodiment uses the above-mentioned headband of the earphone, it generates a damping feeling during specific use, and the user experience is better.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
