Description

Technical Field

[0001] This invention relates to the field of headphone technology, and more particularly to a type of over-ear headphone. Prior Technology

[0002] Over-ear headphones are headphones worn on the head, mainly composed of three parts: the headphone body, the frame, and the headband. Because over-ear headphones don't need to be inserted into the ears, they offer better comfort and are popular among users.

[0003] In existing technologies, to broaden the application range of headphones, the headphone body typically employs a toothed structure for damping and limiting. Specifically, this toothed structure is positioned between the support frame and the headband, allowing the support frame to move relative to the headband, thereby adjusting the distance between the headphone body and the headband to accommodate users with different head diameters. However, due to the spacing between the teeth in the toothed structure, the minimum movement step of the headphone body is usually the distance between two teeth. This results in low adjustment precision for the headphones; that is, the support frame cannot be limited to any position, leading to situations where the headphone body cannot fully fit over the ears, but rather sits slightly higher or lower, affecting the wearing comfort and sound quality of the headphones.

[0004] Therefore, there is an urgent need for a type of over-ear headphone to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a headset to solve the technical problem that existing technologies cannot achieve stepless adjustment.

[0010] Optionally, the connecting sleeve is provided with a first threaded hole, the adjusting member is provided with a second threaded hole, and the connecting member is screwed into the first threaded hole and the second threaded hole to connect the connecting sleeve and the adjusting member.

[0011] Optionally, one of the wall of the first through hole and the outer peripheral wall of the connecting sleeve is provided with a first sliding groove, and the other is provided with a slider. The extending direction of the first sliding groove is the same as the extending direction of the first through hole, and the slider is slidably connected to the first sliding groove along the extending direction of the first sliding groove; and / or, the sliding bracket is provided with a slide rail extending along the extending direction of the first through hole, and the clamping block is provided with a second sliding groove that slides with the slide rail.

[0012] Optionally, one end of the sliding bracket is provided with a collar and a first limiting structure, and the other end of the sliding bracket is provided with a second limiting structure; the collar is connected to the headband housing and is located on the side of the first limiting structure facing away from the second limiting structure, and the adjusting member passes through the collar; the clamping block has a first position and a second position, and when the clamping block is in the first position, the length of the adjusting member extending out of the protrusion is greater than the length of the adjusting member extending out of the protrusion when the clamping block is in the second position; the first limiting structure is used to contact the clamping block located in the first position, and the second limiting structure is used to contact the clamping block located in the second position, so as to limit the movement limit of the clamping block in the extension direction of the first through hole.

[0013] Optionally, the headphone body, the sliding bracket, the adjusting member, and the damping clamping assembly are each provided in twos. The two sliding brackets are disposed at both ends of the headband housing. The two adjusting members are correspondingly inserted through the first through holes of the two sliding brackets. The two damping clamping assemblies are correspondingly connected to the two adjusting members and are used to clamp and fix the corresponding adjusting members to the corresponding sliding brackets. The two headphone bodies are correspondingly connected to the two adjusting members. The headphone also includes a wire. The middle part of the wire is located inside the headband housing. The two ends of the wire pass through the adjusting members and are electrically connected to the two headphone bodies.

[0014] Optionally, the headphones further include a support plate, which is slidably connected to the sliding bracket, and the support plate, the sliding bracket, and the damping clamping assembly are all disposed within the headband housing.

[0016] Optionally, the support plate and the damping clamping assembly are located on the same side of the sliding bracket.

[0017] The headphones provided by this invention have at least the following beneficial effects:

[0018] A sliding bracket is housed within the headband housing. An adjustment member is movably inserted through a first through-hole in the sliding bracket, ensuring that the first through-hole does not restrict the movement of the adjustment member but only guides its direction of movement. One end of the adjustment member extends from the headband housing's outlet and connects to the earphone body, allowing the adjustment member and the connected earphone body to move synchronously. A damping clamping assembly is connected to the adjustment member and used to clamp and fix it to the sliding bracket, achieving a damped sliding connection between the adjustment member and the sliding bracket. When the external force on the adjustment member exceeds a set value, the adjustment member can move relative to the sliding bracket, and the adjustment member... The movement step size is related to the amplitude when the adjustment component is pulled or pushed. Since the adjustment component is limited relative to the sliding bracket by the friction force generated by pressing, the adjustment component can remain stationary at any position of the sliding bracket. The minimum movement step size of the adjustment component can be small, which in turn allows for a smaller movement amplitude of the headphone body, enabling stepless adjustment. This achieves the limitation of the adjustment component and the headphone body at any position, allowing the headphone body to be adjusted to fit perfectly with the user's ears, better securely fastening to the ears and improving the wearing effect of the headphones, thereby ensuring the sound quality and sound effect of the headphones.

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] This embodiment provides a headset that can achieve stepless adjustment, has high adjustment precision, improves wearing comfort, and ensures sound quality.

[0028] As shown in Figures 1 to 10, the over-ear headphones include a headband shell 100, an earphone body (not shown), a sliding bracket 200, an adjustment member 300, and a damping clamping assembly 400. Two earphone bodies are provided, each capable of emitting sound and used to fasten onto the user's ears, allowing the sound emitted by the earphone bodies to enter the ears. The headband shell 100 has an extension opening for the adjustment member 300 to extend. Specifically, the headband shell 100 is elongated, with extension openings at both ends. The adjustment member 300 extends from the extension openings and is connected to the earphone body, so that when the adjustment member 300 moves, it can move the earphone body, thereby adjusting the position of the earphone body relative to the headband shell 100. It should be noted that the connection between the earphone body and the adjustment member 300 is a fixed connection, not an electrical connection.

[0029] The sliding bracket 200 is disposed within the headband housing 100, as shown in Figure 4. The sliding bracket 200 has a first through hole 210 for the adjustment member 300 to pass through. In some optional embodiments, the extending direction of the sliding bracket 200 is the same as the extending direction of the headband housing 100, and the extending direction of the first through hole 210 is the same as the extending direction of the sliding bracket 200. The adjustment member 300 is movably disposed within the first through hole 210 along the extending direction of the first through hole 210, and the adjustment member 300 extends from the protrusion and is connected to the headphone body. By providing the first through hole 210, the movement of the adjustment member 300 can be guided, allowing the adjustment member 300 to move relative to the headband housing 100 along the extending direction of the headband housing 100, thus avoiding interference between the adjustment member 300 and the headband housing 100 during movement.

[0030] For example, the headband housing 100 is also provided with a wire 500. The middle part of the wire 500 is located inside the headband housing 100. The two ends of the wire 500 extend from two protrusions and are electrically connected to the headphone body, so that the two headphone bodies can be electrically connected.

[0031] In this embodiment, the damping clamping assembly 400 is connected to the adjusting member 300 and is used to clamp and fix the adjusting member 300 to the sliding bracket 200, thereby realizing a damped sliding connection between the adjusting member 300 and the sliding bracket 200. It should be noted that clamping and fixing the adjusting member 300 to the sliding bracket 200 by the damping clamping assembly 400 does not limit the adjusting member 300 from moving relative to the sliding bracket 200. Rather, it limits the adjusting member 300 from moving relative to the sliding bracket 200 when no external force is applied. However, when subjected to a set external force, for example, when the adjusting member 300 is pulled or pushed by the part of the adjusting member 300 located outside the headband housing 100, the adjusting member 300 can overcome the friction between itself and the sliding bracket 200 and move relative to the sliding bracket 200, thereby realizing the movement of the adjusting member 300 relative to the sliding bracket 200.

[0032] In some alternative embodiments, the damping clamping assembly 400 has a clamping surface 410 for abutting against the sliding bracket 200, the clamping surface 410 abutting against the sliding bracket 200 for clamping and fixing the adjusting member 300 to the sliding bracket 200.

[0033] The headphones provided in this embodiment have a sliding bracket 200 disposed within a headband housing 100. An adjusting member 300 is movably inserted through a first through hole 210 in the sliding bracket 200, ensuring that the first through hole 210 does not restrict the movement of the adjusting member 300, but only guides its direction of movement. One end of the adjusting member 300 extends from the outlet of the headband housing 100 and connects to the headphone body, allowing the adjusting member 300 and the connected headphone body to move synchronously. A damping clamping assembly 400 is connected to the adjusting member 300 and used to clamp and fix the adjusting member 300 onto the sliding bracket 200, achieving a damped sliding connection between the adjusting member 300 and the sliding bracket 200. When the external force on the adjusting member 300 exceeds a set value, the adjusting member 300... The adjustment component 300 can move relative to the sliding bracket 200, and the movement step of the adjustment component 300 is related to the amplitude when the adjustment component 300 is pulled or pushed. Since the limiting of the adjustment component 300 relative to the sliding bracket 200 is achieved by the friction force generated by pressing, the adjustment component 300 can remain stationary at any position of the sliding bracket 200, and the minimum movement step of the adjustment component 300 can be small, thereby allowing the movement amplitude of the headphone body to be small, achieving stepless adjustment. This realizes the limiting of the adjustment component 300 and the headphone body at any position, so that the headphone body can be adjusted to fit the user's ear perfectly, so as to better fit the ear, improve the wearing effect of the headphones, and thus ensure the sound quality and sound effect of the headphones.

[0034] For example, the sliding bracket 200 can be made of plastic or other non-metallic materials, and this embodiment does not limit this.

[0035] In this embodiment, two sliding brackets 200, two adjusting members 300, and two damping clamping assemblies 400 are provided. Each of the two sliding brackets 200 corresponds to one of the two adjusting members 300, and each of the two damping clamping assemblies 400 corresponds to one of the two adjusting members 300. The two sliding brackets 200 are located at both ends of the headband housing 100, and are positioned close to the ends of the headband housing 100. Each adjusting member 300 passes through the first through hole 210 of one of the two sliding brackets 200, and each of the two damping clamping assemblies 400 is connected to one of the two adjusting members 300, and is used to clamp and fix the corresponding adjusting member 300 to the corresponding sliding bracket 200, so that each adjusting member 300 can achieve a damped sliding connection with the corresponding sliding bracket 200. The two earphone bodies are connected one-to-one with the two adjusting members 300, thereby enabling position adjustment of the two earphone bodies and further improving the wearing comfort of the headphones.

[0036] In this embodiment, as shown in Figure 10, the middle part of the wire 500 is located inside the headband housing 100, and both ends of the wire 500 pass through two adjusting members 300 and are electrically connected to the two earphone bodies. Specifically, one end of the wire 500 passes through the corresponding adjusting member 300 along the axial direction of the adjusting member 300 and is electrically connected to the earphone body connected to the adjusting member 300. In this embodiment, the wire 500 includes a wavy section 510 and an arc-shaped section 520. Two arc-shaped sections 520 are provided and connected to the two ends of the wavy section 510. The arc-shaped sections 520 pass through the adjusting members 300 and are electrically connected to the earphone bodies.

[0037] For example, as shown in Figures 3 and 5, the damping clamping assembly 400 includes a connecting sleeve 420, a clamping block 430, and a connecting member 440. The connecting sleeve 420 is fitted onto the adjusting member 300. As shown in Figure 4, the characteristic side of the sliding bracket 200 has a guide groove 220 communicating with the first through hole 210. The clamping block 430 passes through the guide groove 220 and abuts against the connecting sleeve 420. The connecting member 440 connects the clamping block 430 and the connecting sleeve 420. The clamping block 430 has the aforementioned clamping surface 410, which abuts against the characteristic side.

[0038] In this embodiment, by setting the connecting sleeve 420 to fit onto the adjusting member 300, the strength of the connection between the connecting sleeve 420 and the adjusting member 300 can be improved, thereby ensuring that the connecting sleeve 420 can move with the adjusting member 300 when it moves. The characteristic side can be any side of the sliding bracket 200; for ease of assembly, the characteristic side in this embodiment is an exposed side. The guide groove 220 is used to guide the movement of the clamping block 430, allowing the clamping block 430 to move along the length direction of the guide groove 220 (i.e., the extension direction of the sliding bracket 200). The clamping block 430 abuts against the connecting sleeve 420, allowing the connecting member 440 to connect the connecting sleeve 420 and the clamping block 430 into a whole, reducing the probability of relative displacement between the connecting sleeve 420 and the clamping block 430, and further ensuring that the clamping block 430 and the connecting member 440 can move with the adjusting member 300.

[0039] In this embodiment, the pressing surface 410 abuts against the feature side, resulting in a large contact area between the pressing block 430 and the sliding bracket 200. This increases the friction between the two, improves the pressing effect of the pressing block 430 on the adjusting member 300, reduces the risk of the adjusting member 300 moving relative to the sliding bracket 200 when not under force, and improves the reliability and service life of the headphones.

[0040] For example, the clamping block 430 can be made of non-metallic materials such as plastic, so that there is a large frictional force between the clamping block 430 and the sliding bracket 200, thereby achieving the clamping and fixing of the adjusting member 300. Optionally, the material of the part of the clamping block 430 that contacts the sliding bracket 200 can be a non-slip and wear-resistant material, which is not limited in this embodiment.

[0041] Further optionally, referring to Figure 5, the clamping block 430 is provided with a second through hole 431, the extension direction of the second through hole 431 being perpendicular to the sliding direction of the clamping block 430. A connecting member 440 passes through the second through hole 431, and one end of the connecting member 440 is connected to the connecting sleeve 420, while the other end of the connecting member 440 is provided with a cap 450. The damping clamping assembly 400 in this embodiment also includes an elastic member 460, which is sleeved on the connecting member 440 and located between the cap 450 and the clamping block 430. The elastic member 460 always has a tendency to drive the clamping block 430 to press the adjusting member 300 against the sliding bracket 200, thereby elastically pressing the adjusting member 300 onto the sliding bracket 200. The elasticity of the elastic element 460 ensures that the adjustment element 300 is pressed tightly against the sliding bracket 200. The elastic element 460 can maintain its elasticity for a long time, which can improve the service life of the headphones compared to connecting them only through the connector 440.

[0042] For example, the elastic element 460 is a spring washer, and the connector 440 has a groove. The sidewall of one side of the groove forms the bottom surface of the cap 450. The spring washer is at least partially located in the groove so as to abut against the cap 450. Of course, it is understood that the elastic element 460 can also be other elastic structures, such as a compression spring, and this embodiment does not limit it to this.

[0043] In some optional embodiments, as shown in FIG9, the connecting sleeve 420 is provided with a first threaded hole 421, and as shown in FIG5, the adjusting member 300 is provided with a second threaded hole 310. The connecting member 440 is screwed into the first threaded hole 421 and the second threaded hole 310 to connect the adjusting member 300 and the connecting sleeve 420. In this embodiment, the connecting member 440 is not only used to connect the clamping block 430 and the connecting sleeve 420, but also to connect the adjusting member 300 and the connecting sleeve 420, realizing the multi-purpose use of the connecting member 440. While improving the connection strength between the connecting sleeve 420 and the adjusting member 300, it reduces the number of parts required for connection, resulting in fewer parts in the headset, a simpler structure, and easier assembly.

[0044] Alternatively, the end of the connector 440 abuts against the wire 500 inside the adjusting member 300 to limit the relative position of the wire 500 and the adjusting member 300, so that when the adjusting member 300 moves, the wire 500 can move simultaneously with the adjusting member 300, thereby improving the synchronicity of the movement of the wire 500 and the adjusting member 300.

[0045] In some alternative embodiments, the adjustment member 300 has a small diameter end 320, and the connecting sleeve 420 is fitted onto the small diameter end 320, such that the arrangement of the connecting sleeve 420 does not excessively increase the radial dimension of the headphones in the adjustment member 300.

[0046] For example, one of the holes in the first through hole 210 and the outer peripheral wall of the connecting sleeve 420 is provided with a first groove 230, and the other is provided with a slider 422. The extending direction of the first groove 230 is the same as the extending direction of the first through hole 210. The slider 422 is slidably connected to the first groove 230 along the extending direction of the first groove 230 to guide the movement of the connecting sleeve 420, thereby guiding the movement of the adjusting member 300. The friction between the slider 422 and the first groove 230 can also increase the damping between the connecting sleeve 420 and the sliding bracket 200, further reducing the risk of the connecting sleeve 420 and the adjusting member 300 moving relative to the sliding bracket 200 when no force is applied. As shown in Figure 4, the first groove 230 is provided on the hole wall of the first through hole 210, that is, on the sliding bracket 200. As shown in Figure 5, the slider 422 is provided on the connecting sleeve 420. By placing the slider 422 on the connecting sleeve 420, the size of the slider 422 can be reduced, thereby reducing the overall weight of the headphones.

[0047] Optionally, referring to Figure 4, the sliding bracket 200 is provided with a slide rail 240 extending along the extension direction of the first through hole 210 (i.e., the extension direction of the sliding bracket 200), as shown in Figure 6. The clamping block 430 is provided with a second slide groove 432 that slides and engages with the slide rail 240. The clamping block 430 is slidably connected to the slide rail 240 through the second slide groove 432, so that the slide rail 240 can guide the movement of the clamping block 430. For example, there are two slide rails 240, which are located on both sides of the guide groove 220 in the width direction. Correspondingly, there are two second slide grooves 432, which slide and engage with the two slide rails 240 one by one. In this embodiment, there are two clamping surfaces 410, which are located on the side of the two second slide grooves 432 away from the guide groove 220, and both are in contact with the characteristic side of the sliding bracket 200.

[0048] In some optional embodiments, as shown in FIG3, one end of the sliding bracket 200 is provided with a collar 270 and a first limiting structure 260, and the other end of the sliding bracket 200 is provided with a second limiting structure 250. A clamping block 430 is disposed between the first limiting structure 260 and the second limiting structure 250. Both the first limiting structure 260 and the second limiting structure 250 are used to limit the clamping block 430, thereby limiting the movement limit of the adjusting member 300.

[0049] Please refer to Figure 3. In this embodiment, the collar 270 is connected to the headband housing 100 and is located on the side of the first limiting structure 260 facing away from the second limiting structure 250. The adjusting member 300 passes through the collar 270.

[0050] In this embodiment, the clamping block 430 has a first position and a second position. Specifically, the clamping block 430 has a first position and a second position relative to the sliding bracket 200. When the clamping block 430 is in the first position, the length of the adjusting member 300 extending from the protrusion is greater than the length of the adjusting member 300 extending from the protrusion when the clamping block 430 is in the second position. That is, the clamping block 430 in the first position is closer to the end of the headband housing 100 than the clamping block 430 in the second position. The first limiting structure 260 is used to contact the clamping block 430 in the first position, and the second limiting structure 250 is used to contact the clamping block 430 in the second position to limit the movement limit of the clamping block 430 in the extension direction of the first through hole 210.

[0051] It should be noted that since the collar 270 is located on the side of the first limiting structure 260 facing away from the second limiting structure 250, when the clamping block 430 is in the first position, it abuts or collides with the first limiting structure 260, but does not impact the collar 270. This reduces the probability of the collar 270 shaking due to impact and ensures the stability of the collar 270 position.

[0052] For example, the first limiting structure 260 and the second limiting structure 250 can both be limiting blocks, or the first limiting structure 260 and the second limiting structure 250 can also be the groove wall of the guide groove 220. This embodiment does not limit this.

[0053] Optionally, as shown in Figures 3 and 10, the headphones also include a support plate 600. The support plate 600 is slidably connected to the sliding bracket 200 to provide a radial clamping force on the headband housing 100, allowing the headband housing 100 to be clamped onto the user's head. This ensures a better fit between the headphone body and the user in its thickness direction, preventing sound leakage and further improving sound quality. The support plate 600 has the same shape as the headband housing 100, and both ends of the support plate 600 extend to the two ends of the headband housing 100 to provide deformation force.

[0054] In this embodiment, the support plate 600, the sliding bracket 200, and the damping clamping assembly 400 are all located inside the headband housing 100, which gives the headphones a better overall appearance and also makes the support plate 600, the sliding bracket 200, and the damping clamping assembly 400 dustproof.

[0055] For example, the material of the support piece 600 can be steel or other metals, and this embodiment does not limit it.

[0056] In some optional embodiments, the headband housing 100 includes an upper housing 110 and a lower housing 120 that are fastened together. The lower housing 120 is closer to the geometric center of the headphones than the upper housing 110. That is, the headband housing 100 is arc-shaped, with the lower housing 120 located on the inner ring and the upper housing 110 on the outer ring. For example, the connection method between the upper housing 110 and the lower housing 120 can be snap-fit, bolted, magnetically attached, etc., and this embodiment does not limit this.

[0057] As shown in Figure 3, the lower housing 120 is provided with a mounting groove 121. The support plate 600, the sliding bracket 200 and the damping clamping assembly 400 are all provided in the mounting groove 121, and the sliding bracket 200 is connected to the lower housing 120. By providing the support plate 600, the sliding bracket 200 and the damping clamping assembly 400 in the mounting groove 121 of the lower housing 120, compared with the case where they are connected to the upper housing 110, it is easier to assemble the sliding bracket 200 on the lower housing 120. On the other hand, it is also easier to assemble the upper housing 110 and the lower housing 120, thereby making the final assembly effect of the headphones good.

[0058] For example, the support piece 600 is disposed on the side of the sliding bracket 200 facing away from the bottom wall of the mounting groove 121, so that the support piece 600 can deform with the gap between the sliding bracket 200 and the upper housing 110, having a large deformation space, and can also make full use of the space between the sliding bracket 200 and the upper housing 110 without affecting the connection between the sliding bracket 200 and the lower housing 120, thereby making the overall thickness of the headband housing 100 smaller, which is conducive to the thinning of the headband housing 100.

[0059] In some optional embodiments, as shown in FIG10, the support plate 600 and the damping clamping assembly 400 are disposed on the same side of the sliding bracket 200. The support plate 600 is provided with a relief groove 610, which is used to avoid the damping clamping assembly 400. Specifically, at least a portion of the clamping block 430 is located in the relief groove 610, which is used to avoid the clamping block 430, so that the clamping block 430 and the support plate 600 can be on the same plane. Compared with the arrangement where the support plate 600 extends to the side of the clamping block 430 facing away from the sliding bracket 200, the thickness of the headband shell 100 can be reduced while ensuring the support function of the support plate 600, which is beneficial to the miniaturization and thinning of the headband shell 100. Furthermore, by providing the relief groove 610, the overall weight of the support plate 600 can also be reduced, which is beneficial to the thinning of the headphones.

[0060] In this embodiment, two clearance grooves 610 are provided. The two clearance grooves 610 are used to avoid the clamping blocks 430 of the two damping clamping assemblies 400, which further reduces the thickness and weight of the headband housing 100.

[0061] Further optionally, referring to Figure 10, the support plate 600 is also provided with a strip hole 620. The length direction of the strip hole 620 is the same as the length direction of the support plate 600. The bolt passes through the strip hole 620 and connects the support plate 600 and the sliding bracket 200. The bolt can slide in the strip hole 620 to realize the sliding connection between the support plate 600 and the sliding bracket 200.

[0062] In some optional embodiments, as shown in FIG4, the sliding bracket 200 is provided with a support protrusion 280, which is located on one side of the guide groove 220 and is used to support the support piece 600, so as to avoid affecting its deformation ability due to the support piece 600 being in a suspended state. In this embodiment, the sliding bracket 200 is connected to the lower housing 120 by bolts, and the bolts are located between the support protrusions 280, so that the bolts will not increase the thickness of the headband housing 100. Further optionally, the end of the support protrusion 280 is provided with a sliding protrusion 2a, and a threaded hole is opened on the sliding protrusion 2a. The bolt passes through the strip hole 620 of the support piece 600 and connects to the threaded hole of the sliding protrusion 2a.

[0063] In this embodiment, please continue to refer to Figures 3 and 4. The side wall of the sliding bracket 200 is provided with a buckle 290, and the inner wall of the lower housing 120 is provided with a slot 122 that engages with the buckle 290. The buckle 290 engages in the slot 122, which can realize the positioning of the lower housing 120 and the sliding bracket 200 on the one hand, and improve the connection strength between the lower housing 120 and the sliding bracket 200 on the other hand.

[0064] When assembling the headphones provided in this embodiment, the sliding bracket 200 can be fixed on the lower housing 120 first. Then, the connecting sleeve 420 and the adjusting member 300 are assembled. Next, the adjusting member 300 is controlled to pass through the sliding bracket 200 and the collar 270 and extend out of the outlet. Then, the wire 500 is passed through the adjusting member 300 and connected to the headphone body, the adjusting member 300, and the wire 500. Subsequently, the clamping block 430 is connected to the connecting sleeve 420 through the connecting member 440 to realize the connection between the clamping block 430 and the adjusting member 300. Finally, the support piece 600 is assembled on the sliding bracket 200, and the upper housing 110 is fastened to obtain the headphones.

[0065] When using the headphones provided in this embodiment, the headphone body can be pulled or pushed, causing the headphone body to move the adjustment component 300 relative to the sliding bracket 200. When the adjustment component 300 moves, it can move the pressing block 430 relative to the sliding bracket 200 through the connecting sleeve 420, thus overcoming the friction between the two. When the external force disappears, there is a large frictional force between the pressing block 430 and the sliding bracket 200. Therefore, the adjustment component 300 will not continue to slide relative to the sliding bracket 200, but will remain stationary, thus limiting the position of the headphone body. It should be noted that the frictional force between the sliding bracket 200 and the pressing block 430 is greater than the overall weight of the headphone body and the adjustment component 300, so that the adjustment component 300 will not move automatically, thus having high reliability.
