Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of headphones, and in particular to a headphone adjustment structure and headphones. Background Technology
[0002] Currently, most over-ear headphones on the market use a telescopic mechanism to adjust the length of the earcups to fit different head shapes. The adjustment mechanisms typically employ mechanical structures such as slide rails, racks, or friction plates for positioning and adjustment. However, during prolonged wear, especially during exercise, the oils and sweat secreted by the user's scalp can enter the inner cavity of the adjustment mechanism. This causes the sliding parts within the adjustment mechanism to slide excessively, reducing friction and making it difficult to adjust the headphones to a comfortable position. Consequently, the headphones cannot be adjusted to a suitable position, affecting wearing comfort and the overall headphone experience. Utility Model Content
[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and to provide a headphone adjustment structure and a headset that prevents the headphone adjustment component from sliding excessively.
[0004] The purpose of this disclosure is achieved through the following technical solution:
[0005] An earphone adjustment structure includes an adjustment housing and an adjustment component. The adjustment housing has a first sliding cavity and a second sliding cavity inside. The adjustment component includes a first adjustment rod, a second adjustment rod, and an intermediate connecting rod. The first adjustment rod is connected to one end of the intermediate connecting rod, and the second adjustment rod is connected to the other end of the intermediate connecting rod. The first adjustment rod is slidably disposed in the first sliding cavity, and the second adjustment rod is slidably disposed in the second sliding cavity. The inner walls of the first sliding cavity and the second sliding cavity are both provided with anti-slip layers, allowing the first adjustment rod to slide smoothly relative to the first sliding cavity, and the second adjustment rod to slide smoothly relative to the second sliding cavity.
[0006] In one embodiment, the adjustment box body is further provided with a first groove and a second groove, the first groove and the second groove being disposed opposite to each other, the first groove being connected to the first sliding cavity, and the second groove being connected to the second sliding cavity.
[0007] In one embodiment, the first groove is provided with a first inclined surface, the second groove is provided with a second inclined surface, the first adjusting rod is slidably disposed on the first inclined surface, and the second adjusting rod is slidably disposed on the second inclined surface.
[0008] In one embodiment, the adjustment box further includes a first boss and a second boss, the first boss being located above the first sliding cavity and connected to the periphery of the first groove, and the second boss being located above the second sliding cavity and connected to the periphery of the second groove.
[0009] In one embodiment, the projected area of the first sliding cavity is equal to the projected area of the second sliding cavity.
[0010] In one embodiment, the headphone adjustment structure further includes a cover, the cover having a third groove and a fourth groove, the third groove and the fourth groove being disposed opposite to each other within the cover, the first groove and the third groove together forming the first sliding cavity, and the second groove and the third groove together forming the second sliding cavity.
[0011] In one embodiment, the adjustment box includes a first connecting portion and a second connecting portion, the first protrusion extending downward and connected to the first connecting portion, the second protrusion extending downward and connected to the second connecting portion, and the cover having a first connecting port and a second connecting port, the first connecting portion being connected to the first connecting port, and the second connecting portion being connected to the second connecting port.
[0012] In one embodiment, the headphone adjustment structure further includes an ear cover, which has a first latch and a second latch. The first adjustment rod has a first bend and a second bend, with the first bend engaging with the first latch and the second bend engaging with the second latch.
[0013] In one embodiment, the anti-slip layer is a carbon fiber composite anti-slip coating.
[0014] A headset includes the headphone adjustment structure described in any of the above embodiments.
[0015] Compared with the prior art, this disclosure has at least the following advantages:
[0016] The adjustment box has a first sliding cavity and a second sliding cavity inside, which are arranged opposite to each other. The adjustment component is provided with a first adjustment rod, a second adjustment rod and an intermediate connecting rod. The first adjustment rod is slidably disposed in the first sliding cavity and the second adjustment rod is slidably disposed in the second sliding cavity. The first adjustment rod and the second adjustment rod are respectively connected to the two ends of the intermediate connecting rod. When the first adjustment rod and the second adjustment rod slide to the first sliding cavity and the second sliding cavity respectively to the preset maximum sliding distance, the intermediate connecting rod will abut against the end face of the top of the adjustment box, thereby limiting the maximum adjustment distance of the first adjustment rod and the second adjustment rod. Both the inner walls of the first and second sliding chambers are equipped with anti-slip layers. This prevents excessive sliding of the first and second adjustment rods within these chambers when sweat or oil enters them, as the oil and sweat adhere to the anti-slip layer. This increases the friction between the first and second adjustment rods on the inner walls of the first and second sliding chambers, avoiding adjustment malfunctions caused by excessive sliding and ensuring the stability of the headphone's adjustment structure. Furthermore, the anti-slip layer improves the wear resistance and lifespan of the adjustment rods, further enhancing the overall durability of the headphones. Through precise control of the adjustment distance and effective anti-slip measures, users can enjoy a more comfortable and stable wearing experience, ensuring the long-term effectiveness of the headphones.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0027] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0028] like Figures 1 to 3As shown, an embodiment of the headphone adjustment structure 10 includes an adjustment housing 100 and an adjustment component 200. The adjustment housing 100 has a first sliding cavity 110 and a second sliding cavity 120 inside. The adjustment component 200 is provided with a first adjustment rod 210, a second adjustment rod 220, and an intermediate connecting rod 230. The first adjustment rod 210 is connected to one end of the intermediate connecting rod 230, and the second adjustment rod 220 is connected to the other end of the intermediate connecting rod 230. The first adjustment rod 210 is slidably disposed in the first sliding cavity 110, and the second adjustment rod 220 is slidably disposed in the second sliding cavity 120. The inner walls of both the first sliding cavity 110 and the second sliding cavity 120 are provided with anti-slip layers 500. Because the inner walls of both the first sliding cavity 110 and the second sliding cavity 120 are provided with anti-slip layers 500, the first adjustment rod 210 slides smoothly relative to the first sliding cavity 110, and the second adjustment rod 220 slides smoothly relative to the second sliding cavity.
[0029] In this embodiment, a first sliding cavity 110 and a second sliding cavity 120 are provided inside the adjusting box 100, and the first sliding cavity 110 and the second sliding cavity 120 are arranged opposite to each other. The adjusting member 200 is provided with a first adjusting rod 210, a second adjusting rod 220 and an intermediate connecting rod 230. The first adjusting rod 210 is slidably disposed in the first sliding cavity 110 and the second adjusting rod 220 is slidably disposed in the second sliding cavity 120. The first adjusting rod 210 and the second adjusting rod 220 are respectively connected to the two ends of the intermediate connecting rod 230. When the first adjusting rod 210 and the second adjusting rod 220 slide to the first sliding cavity 110 and the second sliding cavity 120 respectively to the preset maximum sliding distance, the intermediate connecting rod 230 will abut against the end face of the top of the adjusting box 100, thereby limiting the maximum adjustment distance of the first adjusting rod 210 and the second adjusting rod 220. An anti-slip layer 500 is provided on the inner wall of both the first sliding cavity 110 and the second sliding cavity 120. This prevents excessive sliding of the first adjustment rod 210 and the second adjustment rod 220 within the first and second sliding cavities 110 and 120 due to the adhesion of sweat and oil to the anti-slip layer 500 when sweat and oil enter the first sliding cavity 110 or the second sliding cavity 120. This increases the friction between the first adjustment rod and the second adjustment rod on the inner wall of the first and second sliding cavities, preventing adjustment failure caused by excessive sliding and ensuring the stability of the headphone adjustment structure 10. Furthermore, the application of the anti-slip layer 500 also improves the wear resistance and lifespan of the adjustment rods, further enhancing the overall durability of the headphones. Through precise control of the adjustment distance and effective anti-slip, users can obtain a more comfortable and stable wearing experience during use, ensuring the long-term performance of the headphones. It should be noted that the first adjustment rod 210 slides excessively relative to the first sliding cavity 110, and the second adjustment rod 220 slides excessively relative to the second sliding cavity 120. The relative slippage here is expressed as a relative increase in the coefficient of friction of the first adjusting rod 210 in the first sliding cavity 110 and a relative increase in the coefficient of friction of the second adjusting rod 220 in the second sliding cavity 120, so that the first adjusting rod 210 and the second adjusting rod 220 can have an anti-slip effect.
[0030] Furthermore, the anti-slip layer 500 is a carbon fiber composite anti-slip coating. Short-cut carbon fibers are mixed with epoxy resin and sprayed onto the inner walls of the first sliding cavity 110 and the second sliding cavity 120 to better form the anti-slip layer 500. It is further cured to form a granular surface, thereby making the anti-slip layer 500 have a higher coefficient of friction and the property of absorbing grease.
[0031] like Figure 1As shown, in one embodiment, the adjustment box 100 is further provided with a first groove 130 and a second groove 140. The first groove 130 and the second groove 140 are arranged opposite to each other. The first groove 130 is connected to the first sliding cavity 110, and the second groove 140 is connected to the second sliding cavity 120. It can be understood that with the first groove 130 and the second groove 140 arranged opposite to each other, and because the first groove 130 is connected to the first sliding cavity 110 and the second groove 140 is connected to the second movable cavity, when the first adjustment rod 210 passes through the first sliding cavity 110, it can smoothly extend into the first sliding cavity 110 through the first groove 130 to perform sliding motion. Similarly, when the second adjustment rod 220 passes through the second sliding cavity 120, it can smoothly diffuse into the second sliding cavity 120 through the second groove 140 to perform sliding motion.
[0032] Please refer to the following: Figure 1 and Figure 2 In one embodiment, the first groove 130 is provided with a first inclined surface 1310, and the second groove 140 is provided with a second inclined surface 1420. The first adjusting rod 210 slides and extends on the first inclined surface 1310, and the second adjusting rod 220 slides and extends on the second inclined surface 1420. It can be understood that by providing a first curved surface slope in the first groove 130, the first adjusting rod 210 slides and extends on the first inclined surface 1310. Furthermore, due to the curved shape of the first inclined surface 1310, the first adjusting rod 210 is constrained to a certain extent, preventing it from shifting during sliding. Similarly, by providing a second curved surface slope in the second groove 140, the second adjusting rod 220 slides and extends on the second inclined surface 1420, so that the second inclined surface 1420 constrains the second adjusting rod 220, preventing it from shifting during sliding.
[0033] Combination Figure 1 and Figure 2As shown, the adjusting box 100 further includes a first protrusion 150 and a second protrusion 160. The first protrusion 150 is located above the first sliding cavity 110 and is connected to the periphery of the first groove 130. The second protrusion 160 is located above the second sliding cavity 120 and is connected to the periphery of the second groove 140. It can be understood that by positioning the first protrusion 150 and the second protrusion 160 above the first sliding cavity 110 and the second sliding cavity 120 respectively, when the first adjusting rod 210 and the second adjusting rod 220 slide within the first sliding cavity 110 and the second sliding cavity 120 respectively, it prevents the first adjusting rod 210 and the second adjusting rod 220 from disengaging from their positions within the first sliding cavity 110 and the second sliding cavity 120 due to shaking.
[0034] like Figure 1 As shown, in one embodiment, the projected area of the first sliding cavity 110 is equal to the projected area of the second sliding cavity 120. It can be understood that when the projected area of the first sliding cavity 110 is equal to the projected area of the second sliding cavity 120, and the sliding distances of the first adjusting rod 210 and the second adjusting rod 220 within their respective sliding cavities are further aligned, the adjustment amplitudes on the left and right sides can be precisely matched when the user adjusts the earphone fit, avoiding the problem of unbalanced earphone fit caused by inconsistent sliding distances.
[0035] Combination Figures 1 to 3 As shown, in one embodiment, the headphone adjustment structure 10 further includes a cover 300. The cover 300 has a third groove 310 and a fourth groove 320. The third groove 310 and the fourth groove 320 are disposed opposite to each other within the cover 300. The first groove 130 and the third groove 310 together form the first sliding cavity 110, and the second groove 140 and the third groove 310 together form the second sliding cavity 120. It can be understood that when the cover 300 has the third groove 310 and the third groove 310, and the cover 300 is closed with the adjustment box 100, the first groove 130 and the third groove 310 close together, thereby forming the first sliding cavity 110. Further, the first adjustment rod 210 slides within the first sliding cavity 110. Similarly, the first groove 130 and the third groove 310 close together, forming the second sliding cavity 120, allowing the second adjustment rod 220 to slide within the second sliding cavity 120.
[0036] Combination Figure 1 and Figure 3As shown, the adjusting box 100 further includes a first connecting portion 170 and a second connecting portion 180. The first protrusion 150 extends downward and is connected to the first connecting portion 170, and the second protrusion 160 extends downward and is connected to the second connecting portion 180. The cover 300 has a first connecting port and a second connecting port. The first connecting portion 170 is connected to the first connecting port, and the second connecting portion 180 is connected to the second connecting port. It can be understood that by providing the first connecting portion 170 and the second connecting portion 180 in the adjusting box 100, and by providing the first connecting port and the second connecting port in the cover 300, the first connecting portion 170 is fixedly connected to the first connecting port, and the second connecting portion 180 is fixedly connected to the second connecting port, so that the cover 300 and the adjusting box 100 can be stably combined together.
[0037] Please refer to the following: Figure 1 , Figure 4 and Figure 5 In one embodiment, the headphone adjustment structure 10 further includes an ear cover 400, the ear cover 400 having a first latch 410 and a second latch 420 inside, the first adjustment rod 210 having a first bend 2110 and a second bend 2210, the first bend 2110 being engaged with the first latch 410, and the second bend 2210 being engaged with the second latch 420. It is understood that the ear cover component 400 has a first latch 410 and a second latch 420. The first adjusting rod 210 has a first bend 2110, which is the end away from the intermediate connecting rod 230. The second adjusting rod 220 has a second bend 2210, which is the end away from the intermediate connecting rod 230. The first bend 2110 is engaged with the first latch 410, and the second bend 2210 is engaged with the second latch 420, so that one side of the adjusting component 200 is fixed to the ear cover. The first adjusting component 200 and the second adjusting component 200 slide in the first sliding cavity 110 and the second sliding cavity 120 respectively, thereby controlling the adjusting box 100 to change its distance relative to the ear cover.
[0038] This application also provides a headset, including the headphone adjustment structure 10 described in any of the above embodiments. It is understood that by providing an anti-slip layer 500 in the first sliding cavity 110 and an anti-slip layer 500 in the second sliding cavity 120, both anti-slip layers 500 being carbon fiber composite coatings, when sweat and oil enter the first sliding cavity 110 or the second sliding cavity 120, the first adjustment rod 210 and the second adjustment rod 220 will not slide excessively within the first sliding cavity 110 and the second sliding cavity 120 due to the oil and sweat adhering to the anti-slip layer 500 of the first sliding cavity and the second sliding cavity 120. This avoids adjustment failure caused by excessive sliding and ensures the stability of the headphone adjustment structure 10.
[0039] Compared with the prior art, this disclosure has at least the following advantages:
[0040] By providing a first sliding cavity 110 and a second sliding cavity 120 inside the adjusting box 100, with the first sliding cavity 110 and the second sliding cavity 120 being arranged opposite to each other, and the adjusting member 200 being provided with a first adjusting rod 210, a second adjusting rod 220 and an intermediate connecting rod 230 respectively, the first adjusting rod 210 is slidably disposed in the first sliding cavity 110 and the second adjusting rod 220 is slidably disposed in the second sliding cavity 120, and the first adjusting rod 210 and the second adjusting rod 220 are respectively connected to the two ends of the intermediate connecting rod 230, when the first adjusting rod 210 and the second adjusting rod 220 slide to the preset maximum sliding distance in the first sliding cavity 110 and the second sliding cavity 120 respectively, the intermediate connecting rod 230 will abut against the end face of the top of the adjusting box 100, thereby limiting the maximum adjustment distance of the first adjusting rod 210 and the second adjusting rod 220. An anti-slip layer 500 is provided on the inner wall of both the first sliding cavity 110 and the second sliding cavity 120. This prevents excessive sliding of the first adjustment rod 210 and the second adjustment rod 220 within the first and second sliding cavities 110 and 120 due to the adhesion of sweat and oil to the anti-slip layer 500 when sweat and oil enter the first sliding cavity 110 or the second sliding cavity 120. This increases the friction between the first adjustment rod and the second adjustment rod on the inner wall of the first and second sliding cavities, preventing adjustment malfunction caused by excessive sliding and ensuring the stability of the headphone adjustment structure 10. Furthermore, the application of the anti-slip layer 500 also improves the wear resistance and lifespan of the adjustment rods, further enhancing the overall durability of the headphones. Through precise control of the adjustment distance and effective anti-slip, users can obtain a more comfortable and stable wearing experience during use, ensuring the long-term performance of the headphones.
[0041] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
