Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of headphones, and in particular to an adjustable headphone structure and headphones. Background Technology
[0002] In modern life, headphones are widely used for music enjoyment, gaming, and voice calls. Because of the potential for prolonged wear, comfort is a crucial factor for consumers when choosing headphones.
[0003] Existing headphone adjustment mechanisms have several shortcomings. Some headphones use traditional slot-type adjustment bands, which often only allow for fixed adjustments and cannot meet the personalized and precise needs of different users for tightness. For example, if the headband becomes too tight during prolonged use, it may cause excessive pressure on a specific area of the head, resulting in discomfort and even affecting blood circulation.
[0004] For example, Chinese patent document CN119676914A discloses a type of over-ear headphone, which includes a headband and two earpieces. Each earpiece includes a body, a mounting component, and a microphone. The two bodies are respectively connected to both ends of the headband. One end of the mounting component is fixedly mounted to the body, and the other end of the mounting component protrudes from the body and is located on the side of the body facing away from the headband. The microphone is mounted on the end of the mounting component facing away from the body. Although the above-mentioned over-ear headphone eliminates the cumbersome operation of adjusting the microphone position, when wearing headphones for a long time, the inability to adjust the tightness of the headband may cause excessive pressure on the head during prolonged use, thus affecting the wearing experience.
[0005] Therefore, there is an urgent need for a headphone structure that can adjust the tightness of the headband. Utility Model Content
[0006] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an adjustable headband structure and headphones with adjustable headband tightness.
[0007] The purpose of this disclosure is achieved through the following technical solution:
[0008] An adjustable-tightness headphone structure includes a headband, a first headphone assembly, and a second headphone assembly; a first end of the headband is connected to the first headphone assembly, and the other end of the headband is connected to the second headphone assembly;
[0009] The adjustable headphone structure further includes an adjustment strap, a first adjustment member, and a second adjustment member. The headband is provided with an adjustment surface, and the adjustment strap is movably disposed on the adjustment surface. The first adjustment member is slidably disposed on one end of the headband, and the second adjustment member is slidably disposed on the other end of the headband. One end of the adjustment strap passes through the first adjustment member and is connected to the first headphone assembly, and the other end of the adjustment strap passes through the second adjustment member and is connected to the second headphone assembly.
[0010] The first adjustment member is driven to slide away from or towards the first headphone assembly at a first end of the headband, so that the end of the adjustment band adjacent to the first headphone assembly moves away from or towards the adjustment surface; the second adjustment member is driven to slide away from or towards the second headphone assembly at a second end of the headband, so that the end of the adjustment band adjacent to the second headphone assembly moves away from or towards the adjustment surface.
[0011] In one embodiment, the first adjusting member has a first sliding cavity, and the adjusting band passes through the first sliding cavity and is connected to the first earphone assembly.
[0012] In one embodiment, the second adjustment member has a second sliding cavity, and the adjustment band passes through the second sliding cavity and is connected to the second earphone assembly.
[0013] In one embodiment, the adjustment surface is a groove structure, and the adjustment band elastically abuts against the adjustment surface.
[0014] In one embodiment, the inner wall of the first sliding cavity is provided with a first limiting groove, and the adjusting band is disposed in the first limiting groove.
[0015] In one embodiment, the inner wall of the second sliding cavity is provided with a second limiting groove, and the adjusting band is disposed in the second limiting groove.
[0016] In one embodiment, the end face of the first adjusting member is provided with a plurality of first anti-slip protrusions, each of the first anti-slip protrusions being spaced apart from the end face of the first adjusting member; and / or,
[0017] The second adjusting member is provided with a plurality of second anti-slip protrusions, each of the second anti-slip protrusions being spaced apart on the end face of the second adjusting member.
[0018] In one embodiment, the adjustment belt is a flexible belt structure.
[0019] In one embodiment, the first earphone assembly has a first connection port, and a first end of the adjustment strap is fixedly connected to the first connection port; and / or
[0020] The second earphone assembly has a second connection port, and the second end of the adjustment strap is fixedly connected to the second connection port.
[0021] A type of over-ear headphone, comprising the adjustable tightness over-ear headphone structure described in any of the above embodiments.
[0022] Compared with the prior art, this disclosure has at least the following advantages:
[0023] The first and second earphone assemblies are connected to both ends of the headband, allowing them to be positioned opposite each other on either side of the headband. The headband has an adjustment surface with an adjustment band positioned on it. A first adjustment member is slidably positioned at one end of the headband, and a second adjustment member is slidably positioned at the other end. One end of the adjustment band passes through the inner cavity of the first adjustment member, and the other end passes through the inner cavity of the second adjustment member. When the first adjustment member slides away from the first earphone assembly, the adjustment band in the sliding area of the adjustment surface moves away from the adjustment surface. Similarly, when the second adjustment member slides away from the second earphone assembly, the adjustment band in the sliding area of the adjustment surface near the second earphone assembly moves away from the adjustment surface. This causes the adjustment band on the side of the second adjustment member adjacent to the second earphone assembly to move away from the headband, increasing the tension of the adjustment band on the side of the second adjustment member away from the second earphone assembly. Consequently, the two ends of the headband move closer together, allowing the tightness of the headband to be adjusted.
[0024] Conversely, when the first adjusting member slides closer to the first earphone assembly, the adjusting band in the sliding area of the adjusting surface moves closer to and adheres to the adjusting surface. Similarly, when the second adjusting member slides closer to the second earphone assembly, the adjusting band in the sliding area of the adjusting surface near the second earphone assembly moves closer to and adheres to the adjusting surface. This causes the adjusting band on the side of the second adjusting member adjacent to the second earphone assembly to move closer to the headband, reducing the tension of the adjusting band on the side of the second adjusting member away from the second earphone assembly. Consequently, the two ends of the headband move further apart, increasing the tightness of the headband. By sliding the first and second adjusting members at both ends of the headband, and by having the first and second adjusting members pass through the two ends of the adjusting band, the tightness of the headband can be changed by controlling the distance between the adjusting band and the adjusting surface, further meeting the different needs of the wearer.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0036] like Figures 1 to 4 As shown, an adjustable headphone structure 10 according to one embodiment includes a headband 100, a first headphone assembly 200, a second headphone assembly 300, an adjustment strap 400, a first adjustment member 500, and a second adjustment member 600; a first end of the headband 100 is connected to the first headphone assembly 200, and the other end of the headband 100 is connected to the second headphone assembly 300.
[0037] The headband 100 is provided with an adjustment surface 110, and the adjustment strap 400 is movably disposed on the adjustment surface 110. The first adjustment member 500 is slidably disposed on one end of the headband 100, and the second adjustment member 600 is slidably disposed on the other end of the headband 100. One end of the adjustment strap 400 passes through the first adjustment member and is connected to the first earphone assembly 200, and the other end of the adjustment strap 400 passes through the second adjustment member 600 and is connected to the second earphone assembly 300.
[0038] The first adjustment member 500 is driven to slide away from or towards the first headphone assembly 200 at the first end of the headband 100, so that the end of the adjustment band 400 adjacent to the first headphone assembly 200 moves away from or towards the adjustment surface 110; the second adjustment member 600 is driven to slide away from or towards the second headphone assembly 300 at the second end of the headband 100, so that the end of the adjustment band 400 adjacent to the second headphone assembly 300 moves away from or towards the adjustment surface 110.
[0039] In this embodiment, the first earphone assembly 200 and the second earphone assembly 300 are respectively connected to both ends of the headband 100, allowing the first earphone assembly 200 and the second earphone assembly 300 to be positioned opposite each other on both sides of the headband 100. Since the headband 100 has an adjustment surface 110, an adjustment strap 400 is disposed on the adjustment surface 110. The first adjustment member 500 is slidably disposed at one end of the headband 100, and the second adjustment member 600 is slidably disposed at the other end of the headband 100. Because one end of the adjustment strap 400 passes through the inner cavity of the first adjustment member 500, and the other end of the adjustment strap 400 passes through the inner cavity of the second adjustment member 600, when the first adjustment member 500 slides away from the first earphone assembly 200, the adjustment strap 400 in the sliding area of the adjustment surface 110 moves away from the adjustment surface 110. Similarly, when the second adjusting member 600 slides away from the second headphone assembly 300, the adjusting band 400 near the sliding area of the adjusting surface 110 of the second headphone assembly 300 moves away from the adjusting surface 110, thereby causing the adjusting band 400 on the side of the second adjusting member 600 adjacent to the second headphone assembly 300 to move away from the headband 100. This increases the tension of the adjusting band 400 on the side of the second adjusting member 600 away from the second headphone assembly 300, causing the two ends of the headband 100 to come closer together, thus reducing the change in the tightness of the headband 100.
[0040] Conversely, when the first adjusting member 500 slides closer to the first headphone assembly 200, the adjusting band 400 in the sliding area of the adjusting surface 110 approaches and adheres to the adjusting surface 110. Similarly, when the second adjusting member 600 slides closer to the second headphone assembly 300, the adjusting band 400 in the sliding area of the adjusting surface 110 of the second headphone assembly 300 approaches and adheres to the adjusting surface 110. This causes the adjusting band 400 on the side of the second adjusting member 600 adjacent to the second headphone assembly 300 to approach the headband 100, reducing the tension of the adjusting band 400 on the side of the second adjusting member 600 away from the second headphone assembly 300. Consequently, the two ends of the headband 100 move further apart, thereby increasing the tightness of the headband 100. By sliding the first adjusting member 500 and the second adjusting member 600 at both ends of the headband 100, and by passing the first adjusting member 500 and the second adjusting member 600 through both ends of the adjusting band 400, the tightness of the headband 100 can be changed by controlling the distance between the adjusting band 400 and the adjusting surface 110, thereby further meeting the different needs of the wearer.
[0041] Combination Figure 1 and Figure 2As shown, in one embodiment, the first adjusting member 500 has a first sliding cavity 510, and the adjusting strap 400 passes through the first sliding cavity 510 and is connected to the first headphone assembly 200. It can be understood that one end of the headband 100 and one end of the adjusting strap 400 pass through the first sliding cavity 510, and the adjusting strap 400 is in contact with the headband 100. This allows the adjusting member 500 to slide closer to or further away from the headband 100 by controlling the distance the adjusting strap 400 slides through the first sliding cavity 510 relative to the headband 100.
[0042] Combination Figure 1 and Figure 3 As shown, the second adjusting member 600 further includes a second sliding cavity 610, and the adjusting strap 400 passes through the second sliding cavity 610 and is connected to the second headphone assembly 300. It can be understood that one end of the headband 100 and one end of the adjusting strap 400 pass through the second sliding cavity 610, and the other side of the adjusting strap 400 is attached to the other side of the headband 100. This allows the second adjusting member 600 to slide, and the distance through which the second sliding cavity 610 slides relative to the adjusting strap 400 controls the sliding distance of the adjusting strap 400, moving it away from or closer to the adjusting surface 110 of the headband 100.
[0043] like Figure 1 As shown, in one embodiment, the adjustment surface 110 has a groove structure, and the adjustment band 400 elastically abuts against the adjustment surface 110. It can be understood that the adjustment surface 110 has a groove structure, and the cross-sectional area of the adjustment surface is larger than the cross-sectional area of the adjustment band 400, making it easier for the adjustment band 400 to be placed within the groove structure of the adjustment surface, allowing the adjustment band 400 to fit securely onto the headband 100.
[0044] Combination Figure 1 and Figure 2 As shown, in one embodiment, the inner wall of the first sliding cavity 510 is provided with a first limiting groove 5110, and the adjusting band 400 is disposed in the first limiting groove 5110. It can be understood that the first limiting groove 5110 extends along the sliding direction of the first adjusting member 500. When the adjusting band 400 is embedded in the groove, its sidewall forms a wedge-shaped fit with the inclined surface of the groove, which can limit the lateral displacement of the adjusting band 400 during the sliding process and prevent the adjusting band 400 from shifting during the sliding process.
[0045] Combination Figure 1 and Figure 3As shown, in one embodiment, the inner wall of the second sliding cavity 610 is provided with a second limiting groove 6110, and the adjusting belt 400 is disposed in the second limiting groove 6110. Similarly, the second limiting groove 6110 is provided in the second sliding cavity 610 to restrict the side of the adjusting belt 400 from shifting left or right, preventing the adjusting belt 400 from shifting during sliding, thereby improving the smoothness of the sliding of the adjusting belt 400.
[0046] Combination Figure 1 and Figure 2 As shown, further, the end face of the first adjusting member 500 is provided with a plurality of first anti-slip protrusions 520, each of the first anti-slip protrusions 520 being spaced apart from the end face of the first adjusting member 500. It can be understood that the first anti-slip protrusions 520 on the end face of the first adjusting member 500 ensure that when the first adjusting member 500 is installed with the earphone shell, and when the headband 100 is slid only by the two sides of the first adjusting member 500, the first adjusting member 500 will slide within the inner cavity of the headband shell. The friction between the first anti-slip protrusions 520 and the inner wall of the headband shell increases the frictional resistance of the first adjusting member 500, thus preventing excessive friction of the adjusting member.
[0047] Combination Figure 1 and Figure 3 As shown, in two other embodiments, the second adjusting member 600 is provided with a plurality of second anti-slip protrusions 620, with each pair of second anti-slip protrusions 620 spaced apart on the end face of the second adjusting member 600. Similarly, the second anti-slip protrusions 620 on the end face of the second adjusting member 600 ensure that when the second adjusting member 600 is installed with the headband shell, and only slides against the headband 100 through the two sides of the second adjusting member 600, the second adjusting member 600 will slide within the inner cavity of the headband shell. The friction between the second anti-slip protrusions 620 and the inner wall of the headband shell increases the frictional resistance of the sliding of the second adjusting member 600, thus preventing excessive friction of the second adjusting member 600.
[0048] It should be noted that the headband 100 is placed inside the headband housing, thus placing the headband 100 within the headband housing's inner cavity. Headband housings are a common technology in the art and will not be described in detail here.
[0049] like Figure 1 As shown, in one embodiment, the adjustment band 400 is a flexible band structure. It can be understood that the adjustment band 400 is a deformable structure with a certain degree of elasticity, thereby enabling the adjustment band 400 to better control the tightness of the headband 100. The adjustment band 400 can be made of an elastic material (such as silicone or TPU) with high resilience.
[0050] like Figure 4 As shown, in one embodiment, the first earphone assembly 200 has a first connection port 210, and the first end of the adjustment strap 400 is fixedly connected to the first connection port 210. In this embodiment, the first earphone assembly 200 has a first connection port 210, and one end of the adjustment strap 400 is fixedly connected to the first connection port 210, so that the adjustment strap 400 can be securely connected to the first earphone. Preferably, the adjustment strap 400 is connected to the first connection port 210 by a snap-fit connection.
[0051] like Figure 5 As shown, in another embodiment, the second earphone assembly 300 has a second connection port 310, and the second end of the adjustment strap 400 is fixedly connected to the second connection port. It can be understood that by having a second connection port 310 in the second earphone assembly 300 and fixing the other end of the adjustment strap 400 to the second connection port 310, the adjustment strap 400 can be securely connected to the second earphone. Preferably, the adjustment strap 400 is connected to the second connection port 310 via a snap-fit connection.
[0052] This application also includes a headset, comprising the adjustable headphone structure 10 described in any of the above embodiments. It is understood that by sliding the first adjusting member 500 and the second adjusting member 600 at both ends of the headband 100, and with the first adjusting member 500 and the second adjusting member 600 passing through both ends of the adjusting strap 400, the tightness of the headband 100 can be changed by controlling the distance between the adjusting strap 400 and the adjusting surface 110, thereby further meeting the different needs of the wearer.
[0053] Compared with the prior art, this disclosure has at least the following advantages:
[0054] The first earphone assembly 200 and the second earphone assembly 300 are respectively connected to both ends of the headband 100, allowing them to be positioned opposite each other on both sides of the headband 100. Since the headband 100 has an adjustment surface 110, an adjustment strap 400 is disposed on the adjustment surface 110. A first adjustment member 500 is slidably disposed at one end of the headband 100, and a second adjustment member 600 is slidably disposed at the other end of the headband 100. Because one end of the adjustment strap 400 passes through the inner cavity of the first adjustment member 500, and the other end of the adjustment strap 400 passes through the inner cavity of the second adjustment member 600, when the first adjustment member 500 slides away from the first earphone assembly 200, the adjustment strap 400 in the sliding area of the adjustment surface 110 moves away from the adjustment surface 110. Similarly, when the second adjusting member 600 slides away from the second headphone assembly 300, the adjusting band 400 near the sliding area of the adjusting surface 110 of the second headphone assembly 300 moves away from the adjusting surface 110, thereby causing the adjusting band 400 on the side of the second adjusting member 600 adjacent to the second headphone assembly 300 to move away from the headband 100. This increases the tension of the adjusting band 400 on the side of the second adjusting member 600 away from the second headphone assembly 300, causing the two ends of the headband 100 to come closer together, thus reducing the change in the tightness of the headband 100.
[0055] Conversely, when the first adjusting member 500 slides closer to the first headphone assembly 200, the adjusting band 400 in the sliding area of the adjusting surface 110 approaches and adheres to the adjusting surface 110. Similarly, when the second adjusting member 600 slides closer to the second headphone assembly 300, the adjusting band 400 in the sliding area of the adjusting surface 110 of the second headphone assembly 300 approaches and adheres to the adjusting surface 110. This causes the adjusting band 400 on the side of the second adjusting member 600 adjacent to the second headphone assembly 300 to approach the headband 100, reducing the tension of the adjusting band 400 on the side of the second adjusting member 600 away from the second headphone assembly 300. Consequently, the two ends of the headband 100 move further apart, thereby increasing the tightness of the headband 100. By sliding the first adjusting member 500 and the second adjusting member 600 at both ends of the headband 100, and by passing the first adjusting member 500 and the second adjusting member 600 through both ends of the adjusting band 400, the tightness of the headband 100 can be changed by controlling the distance between the adjusting band 400 and the adjusting surface 110, thereby further meeting the different needs of the wearer.
[0056] 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.
