Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a headband assembly and a headset. Background Art

[0002] Headphones are earphones worn on the head and consist of three main parts: the earphone body, the bracket, and the headband. Because they don't need to be inserted into the ears, headphones are more comfortable and are therefore popular with users.

[0003] In the prior art, in order to expand the application range of headphones, the headphone body is usually damped and limited by a toothed structure. Specifically, the toothed structure is provided between the bracket and the headband, and the bracket can move relative to the headband, thereby adjusting the distance between the headphone body and the headband to suit users with different head diameters. A steel plate is usually also provided in the headband, and the bracket is fixedly connected to the steel plate. When the user wears the headphones, they grasp the two headphone bodies with both hands and pry the headphones apart. At the same time, the bracket and the steel plate are pulled and deformed simultaneously. After the headphones are put on the head, the headphone body is released. At this time, based on the restoring force of the bracket and the steel plate, the headphones are clamped on the user's head. However, since the bracket and the steel plate are fixedly connected, and the steel plate is usually provided on the periphery of the bracket, the deformation of the bracket and the steel plate are different, and there is no relative movement between the steel plate and the bracket. As a result, there is a risk of the steel plate and the bracket being broken or damaged, and the connection between the steel plate and the bracket failing, resulting in low reliability.

[0004] Therefore, there is an urgent need for a headset to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a headset with a headband assembly to solve the problem of low reliability in the prior art.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] Headband assembly, including:

[0008] headband housing;

[0009] a sliding bracket, disposed in the headband housing;

[0010] an adjustment structure, disposed on the sliding bracket and connected to the sliding bracket in a damped sliding manner, one end of the adjustment structure extending out of the headband housing and used to connect to the headphone body;

[0011] A support plate is arranged on the sliding bracket, and the support plate is provided with an avoidance groove for the sliding of the adjustment structure; one of the sliding bracket and the support plate is provided with a positioning column, and the other is provided with a sliding groove sleeved on the positioning column, when the support plate moves relative to the sliding bracket, the positioning column slides in the sliding groove.

[0012] Optionally, the adjustment structure includes an adjustment member and a damping block, wherein the damping block is connected to the adjustment member and is used to press and fix the adjustment member to the sliding bracket, so that the adjustment member is connected to the sliding bracket in a damped sliding manner, and one end of the adjustment member extends out of the headband shell.

[0013] Optionally, the supporting plate and the damping block are arranged on the same side of the sliding bracket, and the damping block slides in the avoidance groove.

[0014] Optionally, the headband assembly further includes a connecting member and an elastic member, the damping block is provided with a second through hole, the connecting member is passed through the second through hole, one end of the connecting member is connected to the adjusting member, and the other end is provided with a cap, the diameter of the cap is larger than the aperture of the second through hole, the elastic member is sleeved on the connecting member and is provided between the cap and the damping block, and the elastic member always has a movement tendency to drive the damping block to press the adjusting member on the sliding bracket.

[0015] Optionally, a ring and a first limiting structure are provided at one end of the sliding bracket, and a second limiting structure is provided at the other end of the sliding bracket; the ring is connected to the headband shell and is located on the side of the first limiting structure facing away from the second limiting structure, and the adjusting member is passed through the ring.

[0016] Optionally, the damping block includes a first position and a second position. When the damping block is at the first position, the length of the adjusting member extending from the headband shell is greater than the length of the adjusting member extending from the headband shell when the damping block is at the second position. The first limiting structure is used to contact the damping block at the first position, and the second limiting structure is used to contact the damping block at the second position to limit the movement limit of the damping block.

[0017] Optionally, the sliding bracket is provided with a supporting protrusion, and the supporting sheet is supported on the supporting protrusion.

[0018] Optionally, the headband shell includes an upper shell and a lower shell that are snap-connected, and the lower shell is closer to the geometric center of the headband assembly than the upper shell; the lower shell is provided with a mounting groove, and the sliding bracket and the support plate are both provided in the mounting groove, and the sliding bracket is connected to the lower shell, and the support plate is provided on the side of the sliding bracket facing away from the bottom wall of the mounting groove.

[0019] Optionally, one of the side wall of the sliding bracket and the inner wall of the headband housing is provided with a buckle, and the other is provided with a slot, and the buckle is engaged in the slot.

[0020] A headset comprises the headband assembly as described above, and further comprises an earphone body connected to one end of the adjustment structure extending out of the headband housing.

[0021] Beneficial effects of the utility model:

[0022] The headband assembly and headphones provided by the present invention are slidably connected between the supporting plate and the sliding bracket via the positioning column and the sliding groove, which can reduce the relative stress between the supporting plate and the sliding bracket, so that the supporting plate can move slightly relative to the sliding bracket, thereby avoiding damage to the supporting plate and the sliding bracket caused by deformation of the headband shell. At the same time, an avoidance groove is provided on the supporting plate for sliding of the adjustment structure, that is, the supporting plate will not cover the adjustment structure, so that the headband assembly will not have a large thickness due to the overlap of the supporting plate and the adjustment structure, thereby making the thickness of the headband assembly smaller, thereby making the headband assembly thinner, which is conducive to the lightweight and thinness of the headphones using the headband assembly.

[0023] In addition, the adjustment structure is connected to the headband shell in a damping sliding manner, so that when the external force applied to the adjustment structure exceeds a set value, the adjustment structure can move relative to the headband shell, and the movement step of the adjustment structure is related to the amplitude when the adjustment structure is pulled or pushed. Since the adjustment structure is limited relative to the headband shell by friction, the adjustment structure can be stationary at any position of the headband shell, and the minimum movement step of the adjustment structure can be smaller, thereby making the movement amplitude of the earphone body smaller, and achieving stepless adjustment, and realizing the limitation of the adjustment structure and the earphone body at any position, so that the earphone body can be adjusted to fully match the user's ear, so as to better fit on the ear, thereby improving the wearing effect of the headphone, and thus ensuring the sound quality and sound effect of the headphone.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0039] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0042] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0043] In a first aspect, this embodiment provides a headband assembly for use with headphones, which has high reliability and can be of a small size.

[0044] like Figures 1 to 10 As shown, the headband assembly includes a headband housing 1, a support plate 2, a sliding bracket 12, and an adjustment structure (not shown). The headband housing 1 is an arc-shaped structure with an inner cavity. The support plate 2, sliding bracket 12, and part of the adjustment structure are all located within the headband housing 1. In this embodiment, the sliding bracket 12 is fixedly mounted within the headband housing 1.

[0045] The adjustment structure and the support plate 2 in this embodiment are both arranged on the sliding bracket 12. Figure 2As shown, the sliding bracket 12 is provided with a positioning post 16, and the support plate 2 is provided with a sliding groove 22 that is sleeved on the positioning post 16. When the support plate 2 moves relative to the sliding bracket 12, the positioning post 16 slides within the sliding groove 22. For example, the length direction of the sliding groove 22 is the same as the length direction of the support plate 2. When the support plate 2 moves relative to the sliding bracket 12, the positioning post 16 can slide within the sliding groove 22 along the length direction of the sliding groove 22.

[0046] Specifically, when the headband shell 1 is deformed, the support piece 2 and the sliding bracket 12 will also be deformed, and the deformation amounts of the support piece 2 and the sliding bracket 12 are different. By moving the positioning column 16 in the sliding groove 22, the relative stress between the support piece 2 and the sliding bracket 12 can be reduced, so that the support piece 2 can move slightly relative to the sliding bracket 12, avoiding damage to the support piece 2 and the sliding bracket 12 caused by the deformation of the headband shell 1, and preventing failure of the connection between the support piece 2 and the sliding bracket 12, with high reliability.

[0047] It should be noted that the support sheet 2 can be used to provide radial clamping force to the headband housing 1, allowing the headband housing 1 to be clamped on the user's head, allowing the headphone body to better fit the user in its thickness direction, preventing sound leakage and further improving the sound quality. The shape of the support sheet 2 is the same as that of the headband housing 1, and both ends of the support sheet 2 extend to the two ends of the headband housing 1 to provide deformation force. In addition, an avoidance groove 21 is provided on the support sheet 2 to avoid the adjustment structure so that the adjustment structure will not interfere with the support sheet 2 during the sliding process.

[0048] It should also be noted that the positioning post 16 may be provided on the support sheet 2, and the sliding groove 22 may be provided on the sliding bracket 12, with the length direction of the sliding groove 22 being the same as the length direction of the sliding bracket 12. When the support sheet 2 moves relative to the sliding bracket 12, the support post 16 may also slide within the sliding groove 22. This embodiment is not limited to this.

[0049] Optionally, the support sheet 2 may be made of a metal material or a non-metal material. For example, the support sheet 2 may be a steel sheet.

[0050] Optionally, the adjustment structure in this embodiment is connected to the sliding bracket 12 in a damped sliding manner. The damped sliding connection refers to a sliding connection between the adjustment structure and the sliding bracket 12, but there is damping between the two, so that the friction between the two is relatively large, and the adjustment structure will only slide relative to the sliding bracket 12 when the external force applied to the adjustment structure is greater than a set value. One end of the adjustment structure extends out of the headband shell 1 and is used to connect to the headphone body of the headset. Through the damped sliding connection between the sliding bracket 12 and the adjustment structure, the adjustment structure can be limited relative to the sliding bracket 12, and then the headphone body can be limited relative to the headband shell 1, so as to achieve the adjustment of the distance between the headphone body and the headband shell 1 and the limitation after adjustment.

[0051] In the headband assembly provided by this embodiment, the support piece 2 and the sliding bracket 12 are slidably connected by the positioning column 16 and the sliding groove 22, which can reduce the relative stress between the support piece 2 and the sliding bracket 12, so that the support piece 2 can move slightly relative to the sliding bracket 12, thereby avoiding damage to the support piece 2 and the sliding bracket 12 caused by deformation of the headband shell 1. At the same time, an avoidance groove for the sliding of the adjustment structure is provided on the support piece 2, that is, the support piece 2 will not cover the adjustment structure, so that the headband assembly will not have a large thickness due to the overlap of the support piece 2 and the adjustment structure, thereby making the headband assembly smaller and thinner, which is conducive to the lightweight and thinness of the headphones using the headband assembly.

[0052] In addition, the adjustment structure is connected to the sliding bracket 12 in a damping sliding manner, so that when the external force applied to the adjustment structure exceeds a set value, the adjustment structure can move relative to the sliding bracket 12, and the movement step of the adjustment structure is related to the amplitude when the adjustment structure is pulled or pushed. Since the adjustment structure is limited relative to the sliding bracket 12 by friction, the adjustment structure can be stationary at any position of the sliding bracket 12, and the minimum movement step of the adjustment structure can be smaller, thereby making the movement amplitude of the earphone body smaller, and achieving stepless adjustment, and realizing the limitation of the adjustment structure and the earphone body at any position, so that the earphone body can be adjusted to fully match the user's ear, so as to better fit on the ear, thereby improving the wearing effect of the headset, and thus ensuring the sound quality and sound effect of the headset.

[0053] In this embodiment, the provision of the sliding bracket 12 facilitates the manufacture of the headband housing 1. After the sliding bracket 12 is manufactured, the sliding bracket 12 can be installed within the headband housing 1. Furthermore, the manufacture of the sliding bracket 12 is facilitated, allowing the adjustment structure to be more quickly connected to the sliding bracket 12. Furthermore, by disposing the support plate 2, the adjustment structure, and the sliding bracket 12 within the headband housing 1, the headband assembly has a better overall appearance and is dustproof for the support plate 2, the sliding bracket 12, and the adjustment structure.

[0054] For example, please see Figure 3 The adjustment structure includes an adjustment member 3 and a damping block 4. The damping block 4 is connected to the adjustment member 3 and is used to press and fix the adjustment member 3 to the sliding bracket 12, so that the adjustment member 3 and the sliding bracket 12 are connected in a damped sliding manner, and one end of the adjustment member 3 extends out of the headband shell 1. By providing the adjustment member 3 and the damping block 4, on the one hand, the structure of the adjustment structure is simpler, with fewer components and capable of achieving a damped sliding connection; on the other hand, the damping block 4 presses and fixes the adjustment member 3, thereby achieving higher reliability. In this embodiment, the sliding bracket 12 is provided with a first through hole 126, and the adjustment member 3 can be movably inserted into the first through hole 126.

[0055] In this embodiment, the damping block 4 and the support sheet 2 are located in the same plane and are spaced apart so that the support sheet 2 does not cover the damping block 4. As a result, the overall thickness of the damping block 4 and the support sheet 2 depends on the damping block 4 or the support sheet 2, rather than the sum of the thicknesses of the two, thereby allowing the headband assembly to be thinner.

[0056] In this embodiment, two sliding brackets 12, two adjusting members 3, and two damping blocks 4 are each provided. The two sliding brackets 12 correspond one-to-one to the two adjusting members 3, and the two damping blocks 4 correspond one-to-one to the two adjusting members 3. The two sliding brackets 12 are disposed at both ends of the headband housing 1, and are both disposed near the end of the headband housing 1. The two adjusting members 3 are correspondingly provided through the first through holes 126 of the two sliding brackets 12. The two damping blocks 4 are correspondingly connected to the two adjusting members 3 and are used to press and secure the corresponding adjusting member 3 to the corresponding sliding bracket 12, so that each adjusting member 3 can achieve a damped sliding connection with the corresponding sliding bracket 12.

[0057] In this embodiment, Figure 10 As shown, the middle portion of the wire 9 is located within the headband housing 1, and the two ends of the wire 9 pass through the two adjustment members 3 and are electrically connected to the two earphone bodies. Specifically, one end of the wire 9 passes through the corresponding adjustment member 3 along the axis of the adjustment member 3 and is electrically connected to the earphone body connected to the adjustment member 3. The wire 9 in this embodiment includes a wavy segment 91 and an arc segment 92. There are two arc segments 92, which are connected to the two ends of the wavy segment 91. The arc segments 92 pass through the adjustment member 3 and are electrically connected to the earphone body.

[0058] Alternatively, as Figure 10As shown, when the support sheet 2 is provided with an escape groove 21, the support sheet 2 and the damping block 4 are arranged on the same side of the sliding bracket 12, and the damping block 4 slides in the escape groove 21. That is, the escape groove 21 is used to avoid the damping block 4. In other words, at least a portion of the damping block 4 is located in the escape groove 21, so that the damping block 4 and the support sheet 2 can be in the same plane. Compared with the arrangement in which the support sheet 2 extends to the side of the damping block 4 facing away from the sliding bracket 12, the thickness of the headband assembly can be reduced while ensuring the supporting function of the support sheet 2, which is conducive to the miniaturization and thinning of the headband assembly. In addition, by providing the escape groove 21, the overall weight of the support sheet 2 can be reduced, which is conducive to the thinning and lightness of the headband assembly. For example, the support sheet 2 includes a wide portion 23 and a narrow portion 24. The width of the wide portion 23 is greater than the width of the narrow portion 24. The narrow portion 24 is connected to one end of the wide portion 23 and surrounds the wide portion 23 to form the escape groove 21.

[0059] For example, the damping block 4 can be made of a non-metallic material such as plastic, so that there is a large friction force between the damping block 4 and the sliding bracket 12, thereby achieving a tight fixation of the adjusting member 3. Optionally, the material of the portion of the damping block 4 that contacts the sliding bracket 12 can be a non-slip and wear-resistant material, which is not limited in this embodiment.

[0060] Alternatively, see Figure 6 , the headband assembly also includes a connecting member 5 and an elastic member 6. The damping block 4 is provided with a second through hole 41, and the extension direction of the second through hole 41 is perpendicular to the sliding direction of the damping block 4. The connecting member 5 is passed through the second through hole 41, and one end of the connecting member 5 is connected to the adjusting member 3, and the other end of the connecting member 5 is provided with a cap 7. The elastic member 6 is sleeved on the connecting member 5 and is arranged between the cap 7 and the damping block 4. The elastic member 6 always has a movement tendency to drive the damping block 4 to press the adjusting member 3 on the sliding bracket 12, so as to elastically press the adjusting member 3 on the sliding bracket 12. Relying on the elasticity of the elastic member 6, the adjusting member 3 is tightly pressed on the sliding bracket 12 under the action of the elastic member 6, and the elastic member 6 can maintain an elastic state for a long time. Compared with the method of connecting only through the connecting member 5, the service life of the headphone can be improved.

[0061] For example, the elastic member 6 is a spring washer, the connector 5 is provided with a groove, the sidewall of one side of the groove constitutes the bottom surface of the cap 7, and the spring washer is at least partially located in the groove so as to be able to abut against the cap 7. Of course, it is understandable that the elastic member 6 can also be other elastic structures, such as a compression spring, and this embodiment is not limited to this.

[0062] Alternatively, as Figure 6As shown, one end of the adjustment member 3 located within the headband housing 1 is connected to a connecting sleeve 8, which is connected to the damping block 4 via a connecting member 5. A guide groove 127 communicating with the first through-hole 126 is provided on the characteristic side surface of the sliding bracket 12. The damping block 4 passes through the guide groove 127 and abuts against the connecting sleeve 8. The connecting member 5 connects the damping block 4 and the connecting sleeve 8. The damping block 4 is provided with the aforementioned pressing surface 42, which abuts against the characteristic side surface.

[0063] In some optional embodiments, the connecting sleeve 8 is provided with a first threaded hole (not shown), the adjusting member 3 is provided with a second threaded hole (not shown), and the connecting member 5 is threadedly engaged with the first threaded hole and the second threaded hole to connect the adjusting member 3 to the connecting sleeve 8. In this embodiment, the connecting member 5 is used not only to connect the damping block 4 and the connecting sleeve 8, but also to connect the adjusting member 3 and the connecting sleeve 8. This realizes the multi-purpose use of the connecting member 5. On the basis of improving the connection strength between the connecting sleeve 8 and the adjusting member 3, the number of components required for the connection is reduced, resulting in a headset with fewer parts, a simpler structure, and easier assembly.

[0064] A wire 9 is also provided within the headband housing 1. The middle portion of the wire 9 is located within the headband housing 1. The ends of the wire 9 extend from two extension ports of the headband housing 1 and are electrically connected to the earphone bodies, thereby electrically connecting the two earphone bodies. Optionally, the distal end of the connector 5 abuts against the wire 9 within the adjusting member 3 to constrain the relative position of the wire 9 and the adjusting member 3. This allows the wire 9 to follow the movement of the adjusting member 3, improving synchronization between the movements of the wire 9 and the adjusting member 3.

[0065] In some optional embodiments, the adjusting member 3 has a small-diameter end with a smaller diameter (not shown in the figure), and the connecting sleeve 8 is arranged on the small-diameter end, so that the setting of the connecting sleeve 8 will not excessively increase the radial size of the headset on the adjusting member 3.

[0066] For example, one of the hole wall of the first through hole 126 and the outer peripheral wall of the connecting sleeve 8 is provided with a first slide groove 128, and the other is provided with a slider 81. The extension direction of the first slide groove 128 is the same as the extension direction of the first through hole 126. The slider 81 is slidably connected to the first slide groove 128 along the extension direction of the first slide groove 128, so as to guide the movement of the connecting sleeve 8, thereby guiding the movement of the adjusting member 3. The friction between the slider 81 and the first slide groove 128 can also increase the damping between the connecting sleeve 8 and the sliding bracket 12, further reducing the risk of the connecting sleeve 8 and the adjusting member 3 moving relative to the sliding bracket 12 when no force is applied. Figure 4 As shown, the first sliding groove 128 is arranged on the hole wall of the first through hole 126, that is, arranged on the sliding bracket 12, as shown in FIG. Figure 6As shown, the slider 81 is arranged on the connecting sleeve 8. By arranging the slider 81 on the connecting sleeve 8, the size of the slider 81 can be smaller, thereby reducing the weight of the entire headset.

[0067] Alternatively, see Figure 4 The sliding bracket 12 is provided with a slide rail 129 extending along the extension direction of the first through hole 126 (ie, the extension direction of the sliding bracket 12). Figure 5 As shown, the damping block 4 is provided with a second slide groove 43 that slidably engages with the slide rail 129. The damping block 4 is slidably connected to the slide rail 129 via the second slide groove 43, so that the slide rail 129 can guide the movement of the damping block 4. For example, two slide rails 129 are provided, and the two slide rails 129 are located on either side of the guide groove 127 in the width direction. Correspondingly, two second slide grooves 43 are provided, and they slidably engage with the two slide rails 129 in a one-to-one correspondence. In this embodiment, there are two pressing surfaces 42, which are located on the side of the two second slide grooves 43 facing away from the guide groove 127, and both pressing surfaces 42 are in contact with the characteristic side surface of the sliding bracket 12.

[0068] In some optional embodiments, such as Figure 3 As shown, a collar 13 and a first limiting structure 15 are provided at one end of the sliding bracket 12, and a second limiting structure 14 is provided at the other end of the sliding bracket 12. The damping block 4 is disposed between the first limiting structure 15 and the second limiting structure 14. Both the first limiting structure 15 and the second limiting structure 14 are used to limit the damping block 4, thereby limiting the movement limit of the adjusting member 3.

[0069] Please continue to see Figure 3 In this embodiment, the collar 13 is connected to the sliding bracket 12 and is located on the side of the first limiting structure 15 facing away from the second limiting structure 14 . The adjusting member 3 is passed through the collar 13 .

[0070] In this embodiment, the damping block 4 has a first position and a second position. Specifically, the damping block 4 has a first position and a second position relative to the sliding bracket 12. When the damping block 4 is in the first position, the length of the adjusting member 3 extending from the extension opening is greater than the length of the adjusting member 3 extending from the extension opening when the damping block 4 is in the second position. That is, the damping block 4 in the first position is closer to the end of the sliding bracket 12 than the damping block 4 in the second position. The first limiting structure 15 is used to contact the damping block 4 in the first position, and the second limiting structure 14 is used to contact the damping block 4 in the second position to limit the movement limit of the damping block 4 in the extension direction of the through hole.

[0071] It should be noted that since the ring 13 is arranged on the side of the first limiting structure 15 facing away from the second limiting structure 14, when the damping block 4 is in the first position, it abuts or collides with the first limiting structure 15 without hitting the ring 13, thereby reducing the chance of the ring 13 shaking due to the impact and ensuring the stability of the position of the ring 13.

[0072] Illustratively, the first limiting structure 15 and the second limiting structure 14 may both be limiting blocks, or the first limiting structure 15 and the second limiting structure 14 may also be groove walls of the guide groove 127 , which is not limited in this embodiment.

[0073] In some optional embodiments, the headband housing 1 includes an upper housing 111 and a lower housing 112 that are snap-connected. The lower housing 112 is closer to the geometric center of the headband housing 1 than the upper housing 111. That is, the headband housing 1 is arc-shaped, with the lower housing 112 located at the inner circle and the upper housing 111 located at the outer circle. For example, the connection between the upper housing 111 and the lower housing 112 may be a snap-on connection, a bolted connection, a magnetic connection, etc., which is not limited in this embodiment.

[0074] like Figure 7 As shown, the lower shell 112 is provided with a mounting groove 1121, the support plate 2, the sliding bracket 12 and the damping block 4 are all arranged in the mounting groove 1121, and the sliding bracket 12 is connected to the lower shell 112. By arranging the support plate 2, the sliding bracket 12 and the damping pressing assembly in the mounting groove 1121 of the lower shell 112, compared with the situation of being connected to the upper shell 111, on the one hand, it can facilitate the assembly of the sliding bracket 12 on the lower shell 112, and on the other hand, it can also facilitate the assembly of the upper shell 111 and the lower shell 112, thereby making the final assembly effect of the headband assembly good.

[0075] Exemplarily, the support piece 2 is arranged on the side of the bottom wall of the sliding bracket 12 facing away from the mounting groove 1121, so that the support piece 2 can be deformed to facilitate the gap between the sliding bracket 12 and the upper shell 111, has a larger deformation space, and can also fully facilitate the space between the sliding bracket 12 and the upper shell 111, without affecting the connection between the sliding bracket 12 and the lower shell 112, thereby making the overall thickness of the headband shell 1 smaller, which is conducive to the thinness of the headband assembly.

[0076] In this embodiment, two avoidance grooves 21 are provided, and the two avoidance grooves 21 are used to avoid the damping blocks 4 of the two damping and pressing assemblies, thereby further reducing the thickness and weight of the headband housing 1.

[0077] Alternatively, see Figure 10 , the bolt passes through the sliding slot 22 and connects the support plate 2 and the sliding bracket 12. In some optional embodiments, such as Figure 4As shown, the sliding bracket 12 is provided with a support protrusion 121, which is located on one side of the guide groove 127 and is used to support the support plate 2 to prevent the deformation ability of the support plate 2 from being affected by the support plate 2 being in a suspended state. Further, optionally, the support protrusion 121 is provided with a second connecting hole 124, and a bolt passes through the sliding groove 22 of the support plate 2 and connects to the second connecting hole 124, thereby limiting the position of the support plate 2 and the sliding bracket 12 in the thickness direction of the support plate 2, while not restricting the movement of the support plate 2 relative to the sliding bracket 12 in the length direction of the support plate 2.

[0078] For example, the positioning column 16 is set on the support protrusion 121. The positioning column 16 slides in the sliding groove 22 along the length direction of the sliding groove 22 and can also guide the sliding of the support plate 2 relative to the sliding bracket 12, so that the support plate 2 slides relative to the sliding bracket 12 along a preset direction.

[0079] Exemplarily, multiple groups of positioning posts 16 and sliding grooves 22 are provided in a one-to-one correspondence to further improve the reliability of the sliding connection between the supporting piece 2 and the sliding bracket 12 .

[0080] In this embodiment, Figure 4 As shown, the sliding bracket 12 is provided with a first connecting hole 123, the bolt passes through the first connecting hole 123 and is connected to the lower shell 112, and the first connecting hole 123 is located between the supporting protrusions 121, so that the setting of the bolt located in the first connecting hole 123 will not additionally increase the thickness of the headband shell 1.

[0081] In this embodiment, Figure 4 and Figure 7 As shown, the side wall of the sliding bracket 12 is provided with a buckle 122, and the inner wall of the lower shell 112 of the headband housing 1 is provided with a slot 1122 that engages with the buckle 122. The buckle 122 is engaged in the slot 1122, which can not only achieve the positioning of the lower shell 112 and the sliding bracket 12, but also improve the connection strength between the lower shell 112 and the sliding bracket 12. Of course, it is understandable that the side wall of the sliding bracket 12 can also be provided with the slot 1122, and the inner wall of the lower shell 112 of the headband housing 1 can also be provided with the buckle 122, and this embodiment is not limited to this.

[0082] In a second aspect, this embodiment provides a headset that can have a smaller size and a lighter weight.

[0083] Specifically, the headset includes the headband assembly as in the first aspect and further includes an earphone body connected to one end of the adjustment structure extending out of the headband housing 1 .

[0084] In this embodiment, two earphone bodies are provided, and the two earphone bodies are connected to the two adjusting members 3 in a one-to-one correspondence, thereby enabling the positions of the two earphone bodies to be adjusted, further improving the wearing comfort of the headset.

[0085] When assembling the headphones provided in this embodiment, the sliding bracket 12 can be first fixed to the lower shell 112. Then, the connecting sleeve 8 and the adjusting member 3 are assembled. Next, the adjusting member 3 is controlled to pass through the sliding bracket 12 and the collar 13 and extend out of the extension port. Then, the wire 9 is passed through the adjusting member 3 and the headphone body is connected to the adjusting member 3 and the wire 9. Subsequently, the damping block 4 is connected to the connecting sleeve 8 via the connecting member 5 to achieve the connection between the damping block 4 and the adjusting member 3. Finally, the support plate 2 is assembled on the sliding bracket 12 and the upper shell 111 is buckled to assemble the headphones.

[0086] When using the headset provided in this embodiment, the headset body can be pulled or pushed so that the headset body drives the adjusting member 3 to slide relative to the sliding bracket 12. When the adjusting member 3 moves, it can drive the damping block 4 to slide relative to the sliding bracket 12 through the connecting sleeve 8 to overcome the friction between the two and move. When the external force disappears, there is a large friction between the damping block 4 and the sliding bracket. Therefore, the adjusting member 3 will not continue to slide relative to the sliding bracket 12, but will remain in a stationary state, thereby limiting the position of the headset body. It should be noted that the friction between the sliding bracket 12 and the damping block 4 is greater than the overall gravity of the headset body and the adjusting member 3, so that the adjusting member 3 will not move automatically, and has high reliability.

[0087] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
