Description

Technical Field

[0001] The present invention relates to the technical field of earphones, and in particular to a headset. Background Art

[0002] Headphones are headphones worn on the head, mainly composed of three parts: the headphone body, the bracket, and the headband. Headphones are comfortable because they do not need to be inserted into the ears, and are favored by users.

[0003] In the prior art, in order to increase the application range of headphones, the headphone body is usually damped and limited by a toothed structure. Specifically, the toothed structure is arranged 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. However, due to the intervals between the teeth of the toothed structure, the minimum moving step length of the headphone body is usually the distance between two teeth, resulting in low adjustment accuracy of the headphone, that is, the bracket cannot be limited at any position, and the headphone body cannot be completely buckled on the ear, but may be biased upward or downward, affecting the wearing comfort and sound quality of the headphone.

[0004] Therefore, a headset is urgently needed to solve the above problems. Summary of the invention

[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] This embodiment provides a headphone that can achieve stepless adjustment, has high adjustment accuracy, improves wearing comfort, and ensures sound quality.

[0046] like Figures 1 to 10As shown, the headset includes a headband shell 100, an earphone body (not shown in the figure), a sliding bracket 200, an adjusting member 300 and a damping and clamping assembly 400. Among them, there are two earphone bodies, both of which can produce sound and are used to snap on the two ears of the user so that the sound emitted by the earphone body can enter the ears. The headband shell 100 is provided with an extension port for the adjusting member 300 to extend out. Specifically, the headband shell 100 is in the shape of an elongated strip, and both ends thereof have extension ports. The adjusting member 300 extends out of the extension port and is connected to the earphone body, so that when the adjusting member 300 moves, it can drive the earphone body to move, thereby realizing the adjustment of 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 adjusting member 300 is a fixed connection, not an electrical connection.

[0047] The sliding bracket 200 is disposed in the headband housing 100. Figure 4 As shown, the sliding bracket 200 is provided with a first through hole 210 for the adjustment member 300 to pass through. In some optional embodiments, the extension direction of the sliding bracket 200 is the same as the extension direction of the headband housing 100, and the extension direction of the first through hole 210 is the same as the extension direction of the sliding bracket 200. The adjustment member 300 is movably passed through the first through hole 210 along the extension direction of the first through hole 210, and the adjustment member 300 extends from the extension port and is connected to the earphone body. By providing the first through hole 210, the movement of the adjustment member 300 can be guided, so that the adjustment member 300 can move relative to the headband housing 100 along the extension direction of the headband housing 100, avoiding interference between the adjustment member 300 and the headband housing 100 during the movement.

[0048] Exemplarily, a wire 500 is further provided in the headband housing 100, the middle part of the wire 500 is located in the headband housing 100, and both ends of the wire 500 extend out from two extension ports respectively and are electrically connected to the earphone body, so that the two earphone bodies can be electrically connected.

[0049] The damping pressing assembly 400 in this embodiment is connected to the adjusting member 300, and is used to press and fix the adjusting member 300 to the sliding bracket 200, thereby realizing the damping sliding connection between the adjusting member 300 and the sliding bracket 200. It should be noted that the damping pressing assembly 400 pressing and fixing the adjusting member 300 to the sliding bracket 200 does not limit the adjusting member 300 to be unable to move relative to the sliding bracket 200, but limits the adjusting member 300 to be unable to move relative to the sliding bracket 200 when not acted upon by an external force, and when acted upon by an external force of a set value, for example, when the adjusting member 300 is pulled or pushed by the portion of the adjusting member 300 located outside the headband housing 100, the adjusting member 300 can overcome the friction between it 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.

[0050] In some optional embodiments, the damping pressing assembly 400 has a pressing surface 410 for abutting against the sliding bracket 200 , and the pressing surface 410 abuts against the sliding bracket 200 to press and fix the adjusting member 300 to the sliding bracket 200 .

[0051] In the headset provided in this embodiment, the sliding bracket 200 is arranged in the headband shell 100, and the adjusting member 300 can be movably inserted into the first through hole 210 of the sliding bracket 200, so that the first through hole 210 will not limit the movement of the adjusting member 300, and can only guide the moving direction of the adjusting member 300. One end of the adjusting member 300 extends out from the extension port of the headband shell 100 and is connected to the headset body, so that the adjusting member 300 and the headset body connected thereto can move synchronously. The damping pressing assembly 400 is connected to the adjusting member 300 and is used to press and fix the adjusting member 300 on the sliding bracket 200, so that the adjusting member 300 and the sliding bracket 200 realize a damping sliding connection. When the external force applied to the adjusting member 300 exceeds a set value, the adjusting member 300 The joint part 300 can move relative to the sliding bracket 200, and the moving step length of the adjusting part 300 is related to the amplitude when pulling or pushing the adjusting part 300. Since the adjustment part 300 is limited relative to the sliding bracket 200 by the friction force generated by pressing, the adjusting part 300 can be stationary at any position of the sliding bracket 200, and the minimum moving step length of the adjusting part 300 can be smaller, thereby making the movement amplitude of the earphone body smaller, and achieving stepless adjustment, thereby achieving the limitation of the adjusting part 300 and the earphone body at any position, so that the earphone body can be adjusted to fully cooperate with the user's ear, so as to better fit on the ear, thereby improving the wearing effect of the headphone, and thereby ensuring the sound quality and sound effect of the headphone.

[0052] Exemplarily, the sliding bracket 200 may be made of plastic or other non-metallic materials, which is not limited in this embodiment.

[0053] In this embodiment, two sliding brackets 200, adjusting members 300 and damping and pressing assemblies 400 are provided. The two sliding brackets 200 correspond to the two adjusting members 300 one by one, and the two damping and pressing assemblies 400 correspond to the two adjusting members 300 one by one. The two sliding brackets 200 are arranged at both ends of the headband housing 100, and are both arranged close to the end of the headband housing 100. The two adjusting members 300 are correspondingly penetrated through the first through holes 210 of the two sliding brackets 200, and the two damping and pressing assemblies 400 are correspondingly connected to the two adjusting members 300, and are used to press and fix the corresponding adjusting members 300 to the corresponding sliding brackets 200, so that each adjusting member 300 can achieve damping sliding connection with the corresponding sliding bracket 200. The two earphone bodies are connected to the two adjusting members 300 one by one, so that the position adjustment of the two earphone bodies can be achieved, and the wearing comfort of the headphone is further improved.

[0054] In this embodiment, Fig.10 As shown, the middle of the wire 500 is located in the headband housing 100, and the two ends of the wire 500 pass through the two adjustment members 300 respectively and are electrically connected to the two earphone bodies. Specifically, one end of the wire 500 passes through the corresponding adjustment member 300 along the axial direction of the adjustment member 300 and is electrically connected to the earphone body connected to the adjustment member 300. The wire 500 in this embodiment includes a wavy segment 510 and an arc segment 520, two arc segments 520 are provided and connected to the two ends of the wavy segment 510, and the arc segment 520 is passed through the adjustment member 300 and is electrically connected to the earphone body.

[0055] For example, Figure 3 and Figure 5 As shown, the damping and pressing assembly 400 includes a connecting sleeve 420, a pressing block 430 and a connecting member 440. The connecting sleeve 420 is sleeved on the adjusting member 300, as shown in FIG. Figure 4 As shown, the characteristic side of the sliding bracket 200 is provided with a guide groove 220 connected to 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, and the clamping block 430 is provided with the above-mentioned clamping surface 410, and the clamping surface 410 abuts against the characteristic side.

[0056] In this embodiment, by setting the connecting sleeve 420 to be sleeved on 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 when the adjusting member 300 moves, the connecting sleeve 420 can follow the movement of the adjusting member 300. The characteristic side is any side of the sliding bracket 200. In order to facilitate assembly, the characteristic side in this embodiment is the side that can be exposed. The guide groove 220 is used to guide the movement of the clamping block 430, so that the clamping block 430 can 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, so that the connecting member 440 can 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 movement of the adjusting member 300.

[0057] The clamping surface 410 in this embodiment abuts against the characteristic side surface, so that there is a larger contact area between the clamping block 430 and the sliding bracket 200, which can increase the friction between the two, improve the clamping effect of the clamping block 430 on the adjusting member 300, reduce the risk of the adjusting member 300 moving relative to the sliding bracket 200 when no force is applied, and improve the reliability and service life of the headset.

[0058] For example, the pressing block 430 may be made of non-metallic material such as plastic, so that there is a large friction force between the pressing block 430 and the sliding bracket 200, thereby achieving the pressing and fixing of the adjusting member 300. Optionally, the material of the portion of the pressing block 430 that contacts the sliding bracket 200 may be a non-slip and wear-resistant material, which is not limited in this embodiment.

[0059] Alternatively, see Figure 5 The pressing block 430 is provided with a second through hole 431, and the extension direction of the second through hole 431 is perpendicular to the sliding direction of the pressing block 430. The connecting member 440 is inserted into the second through hole 431, and one end of the connecting member 440 is connected to the connecting sleeve 420, and the other end of the connecting member 440 is provided with a cap 450. The damping pressing assembly 400 in this embodiment also includes an elastic member 460, which is sleeved on the connecting member 440 and arranged between the cap 450 and the pressing block 430. The elastic member 460 always has a movement tendency to drive the pressing block 430 to press the adjusting member 300 on the sliding bracket 200, so as to realize the elastic pressing of the adjusting member 300 on the sliding bracket 200. Relying on the elasticity of the elastic member 460, the adjusting member 300 is tightly pressed onto the sliding bracket 200 under the action of the elastic member 460, and the elastic member 460 can maintain an elastic state for a long time. Compared with the method of connecting only through the connecting member 440, the service life of the headset can be improved.

[0060] Exemplarily, the elastic member 460 is a spring washer, the connecting member 440 is provided with a groove, the side wall on one side of the groove constitutes the bottom surface of the cap 450, and the spring washer is at least partially located in the groove so as to be able to abut against the cap 450. Of course, it can be understood that the elastic member 460 can also be other elastic structures, such as a compression spring, which is not limited in this embodiment.

[0061] In some optional embodiments, such as Fig. 9 As shown, the connecting sleeve 420 is provided with a first threaded hole 421. Figure 5 As shown, the adjusting member 300 is provided with a second threaded hole 310, and the connecting member 440 is threadedly connected with the first threaded hole 421 and the second threaded hole 310 to connect the adjusting member 300 and the connecting sleeve 420. The connecting member 440 in this embodiment is not only used to connect the pressing block 430 and the connecting sleeve 420, but also used to connect the adjusting member 300 and the connecting sleeve 420, so that the connecting member 440 is used for multiple purposes. On the basis of improving the connection strength between the connecting sleeve 420 and the adjusting member 300, the parts required for the connection are reduced, so that the headset has fewer parts, a simpler structure, and is easy to assemble.

[0062] Further optionally, the end of the connecting member 440 abuts against the wire 500 in 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 synchronization of the movement of the wire 500 and the adjusting member 300.

[0063] In some optional embodiments, the adjusting member 300 has a small diameter end 320 with a smaller diameter, and the connecting sleeve 420 is sleeved on the small diameter end 320, so that the setting of the connecting sleeve 420 does not excessively increase the radial size of the headset in the adjusting member 300.

[0064] Exemplarily, one of the hole wall of the first through hole 210 and the outer peripheral wall of the connecting sleeve 420 is provided with a first slide groove 230, and the other is provided with a slider 422. The extension direction of the first slide groove 230 is the same as the extension direction of the first through hole 210. The slider 422 is slidably connected to the first slide groove 230 along the extension direction of the first slide groove 230, so as 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 slide 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 without force. Figure 4 As shown, the first slide groove 230 is arranged on the hole wall of the first through hole 210, that is, arranged on the sliding bracket 200. Figure 5As shown, the slider 422 is disposed on the connection sleeve 420. By disposing the slider 422 on the connection sleeve 420, the size of the slider 422 can be smaller, thereby reducing the overall weight of the headset.

[0065] Optionally, see Figure 4 The sliding bracket 200 is provided with a slide rail 240 extending along the extension direction of the first through hole 210 (ie, the extension direction of the sliding bracket 200), as shown in FIG. Figure 6 As shown, the pressing block 430 is provided with a second slide groove 432 that is slidably matched with the slide rail 240. The pressing 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 pressing block 430. Exemplarily, there are two slide rails 240, and the two slide rails 240 are arranged on both sides of the guide groove 220 in the width direction. Correspondingly, there are two second slide grooves 432, and they are slidably matched with the two slide rails 240 in a one-to-one correspondence. In this embodiment, there are two pressing surfaces 410, and the two pressing surfaces 410 are arranged 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 surface of the sliding bracket 200.

[0066] In some optional embodiments, such as Figure 3 As shown, a collar 270 and a first limiting structure 260 are provided at one end of the sliding bracket 200, and a second limiting structure 250 is provided at the other end of the sliding bracket 200. The pressing block 430 is provided between the first limiting structure 260 and the second limiting structure 250, and both the first limiting structure 260 and the second limiting structure 250 are used to limit the pressing block 430, thereby limiting the movement limit of the adjusting member 300.

[0067] Please continue to see Figure 3 In this embodiment, the ring 270 is connected to the headband housing 100 and is located on a side of the first limiting structure 260 facing away from the second limiting structure 250 . The adjusting member 300 is inserted through the ring 270 .

[0068] In this embodiment, the pressing block 430 has a first position and a second position. Specifically, the pressing block 430 has a first position and a second position relative to the sliding bracket 200. When the pressing block 430 is located at the first position, the length of the adjusting member 300 extending from the extension port is greater than the length of the adjusting member 300 extending from the extension port when the pressing block 430 is located at the second position, that is, the pressing block 430 at the first position is closer to the end of the headband housing 100 than the pressing block 430 at the second position. The first limiting structure 260 is used to contact the pressing block 430 at the first position, and the second limiting structure 250 is used to contact the pressing block 430 at the second position to limit the movement limit of the pressing block 430 in the extension direction of the first through hole 210.

[0069] It should be noted that since the ring 270 is arranged 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 without hitting the ring 270, thereby reducing the probability of the ring 270 shaking due to the impact and ensuring the stability of the position of the ring 270.

[0070] Exemplarily, the first limiting structure 260 and the second limiting structure 250 may both be limiting blocks, or the first limiting structure 260 and the second limiting structure 250 may also be groove walls of the guide groove 220 , which is not limited in this embodiment.

[0071] Alternatively, if Figure 3 and Fig.10 As shown, the headset further includes a support sheet 600. The support sheet 600 is slidably connected to the sliding bracket 200, and is used to provide a clamping force in the radial direction of the headband housing 100, so that the headband housing 100 can be clamped on the user's head, so that the headset body can better fit the user in the thickness direction, prevent sound leakage, and further improve the sound effect. The shape of the support sheet 600 is the same as that of the headband housing 100, and both ends of the support sheet 600 extend to the two ends of the headband housing 100 to provide deformation force.

[0072] The support sheet 600, the sliding bracket 200 and the damping and pressing assembly 400 in this embodiment are all arranged in the headband shell 100, so that the headset has a better overall appearance and can also achieve dust prevention of the support sheet 600, the sliding bracket 200 and the damping and pressing assembly 400.

[0073] Exemplarily, the material of the support sheet 600 may be steel, or other metals, which is not limited in this embodiment.

[0074] In some optional embodiments, the headband housing 100 includes an upper housing 110 and a lower housing 120 that are snap-connected, and the lower housing 120 is closer to the geometric center of the headset than the upper housing 110, that is, the headband housing 100 is arc-shaped, the lower housing 120 is located in the inner circle, and the upper housing 110 is located in the outer circle. For example, the connection between the upper housing 110 and the lower housing 120 can be a snap connection, a bolt connection, a magnetic connection, etc., which is not limited in this embodiment.

[0075] like Figure 3As shown, the lower shell 120 is provided with a mounting groove 121, and the supporting plate 600, the sliding bracket 200 and the damping and clamping assembly 400 are all arranged in the mounting groove 121, and the sliding bracket 200 is connected to the lower shell 120. By arranging the supporting plate 600, the sliding bracket 200 and the damping and clamping assembly 400 in the mounting groove 121 of the lower shell 120, compared with the situation of being connected to the upper shell 110, on the one hand, it is convenient to assemble the sliding bracket 200 on the lower shell 120, and on the other hand, it is also convenient to assemble the upper shell 110 and the lower shell 120, thereby making the final assembly effect of the headset good.

[0076] Exemplarily, the support sheet 600 is arranged on the side of the bottom wall of the sliding bracket 200 facing away from the mounting groove 121, so that the support sheet 600 can be deformed to facilitate the gap between the sliding bracket 200 and the upper shell 110, has a larger deformation space, and can also fully facilitate the space between the sliding bracket 200 and the upper shell 110, and will not affect the connection between the sliding bracket 200 and the lower shell 120, thereby making the overall thickness of the headband shell 100 smaller, which is conducive to the thinness of the headband shell 100.

[0077] In some optional embodiments, such as Fig.10 As shown, the support sheet 600 and the damping and pressing assembly 400 are arranged on the same side of the sliding bracket 200, and the support sheet 600 is provided with an avoidance groove 610, which is used to avoid the damping and pressing assembly 400. Specifically, at least part of the pressing block 430 is located in the avoidance groove 610, and the avoidance groove 610 is used to avoid the pressing block 430, so that the pressing block 430 and the support sheet 600 can be in the same plane. Compared with the arrangement mode in which the support sheet 600 extends to the side of the pressing block 430 facing away from the sliding bracket 200, the thickness of the headband housing 100 can be reduced while ensuring the supporting function of the support sheet 600, which is conducive to the miniaturization and thinness of the headband housing 100. In addition, by providing the avoidance groove 610, the overall weight of the support sheet 600 can be reduced, which is conducive to the thinness of the headphone.

[0078] In this embodiment, two avoidance grooves 610 are provided, and the two avoidance grooves 610 are used to avoid the pressing blocks 430 of the two damping and pressing assemblies 400 , thereby further reducing the thickness and weight of the headband housing 100 .

[0079] Alternatively, see Fig.10 The support sheet 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 sheet 600, the bolt passes through the strip hole 620 and connects the support sheet 600 and the sliding bracket 200, and the bolt can slide in the strip hole 620 to realize the sliding connection between the support sheet 600 and the sliding bracket 200.

[0080] In some optional embodiments, such as Figure 4 As shown, the sliding bracket 200 is provided with a supporting protrusion 280, and the supporting protrusion 280 is located on one side of the guide groove 220, and is used to support the above-mentioned supporting sheet 600 to prevent the supporting sheet 600 from being in a suspended state and affecting its deformation ability. In this embodiment, the sliding bracket 200 is connected to the lower shell 120 by bolts, and the bolts are located between the supporting protrusions 280, so that the setting of the bolts does not increase the thickness of the headband shell 100.

[0081] In this embodiment, please continue to refer to Figure 3 and Figure 4 The side wall of the sliding bracket 200 is provided with a buckle 290, and the inner wall of the lower shell 120 is provided with a slot 122 that is engaged with the buckle 290. The buckle 290 is engaged in the slot 122, which can, on the one hand, realize the positioning of the lower shell 120 and the sliding bracket 200, and on the other hand, can also improve the connection strength between the lower shell 120 and the sliding bracket 200.

[0082] When assembling the headset provided in this embodiment, the sliding bracket 200 can be first fixed on the lower shell 120, and 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 from the extension port, and then the wire 500 is passed through the adjusting member 300, and the headset body is connected with the adjusting member 300 and the wire 500. Subsequently, the pressing block 430 is connected to the connecting sleeve 420 through the connecting member 440 to achieve the connection between the pressing block 430 and the adjusting member 300. Finally, the supporting sheet 600 is assembled on the sliding bracket 200, and the upper shell 110 is buckled to assemble the headset.

[0083] When using the headset provided in this embodiment, the headset body can be pulled or pushed so that the headset body drives the adjustment member 300 to slide relative to the sliding bracket 200. When the adjustment member 300 moves, it can drive the clamping block 430 to slide relative to the sliding bracket 200 through the connecting sleeve 420 to overcome the friction between the two and move. When the external force disappears, there is a large friction between the clamping block 430 and the sliding bracket. Therefore, the adjustment member 300 will not continue to slide relative to the sliding bracket 200, but will be in a stationary state, thereby achieving the limit of the headset body. It should be noted that the friction between the sliding bracket 200 and the clamping block 430 is greater than the overall gravity of the headset body and the adjustment member 300, so that the adjustment member 300 will not move automatically, and has high reliability.
