Description

Technical Field

[0001] This disclosure relates to the technical field of headphones, and in particular to a headphone structure and headphones with a detachable connecting bracket. Background Technology

[0002] Over-ear headphones are widely used in many scenarios such as audio entertainment, office communication, and sports and fitness due to their advantages such as stable wearing and strong immersive sound quality. Their core structure usually includes ear covers for wrapping the ears, connecting brackets for connecting the ear covers to the headband, and the headband body. The stability and flexibility of the connection between the ear covers and the connecting brackets directly affect the user experience, maintenance convenience, and personalization adaptability of the headphones.

[0003] Currently, most headphones on the market use a fixed connection between the earcups and the connecting bracket, such as by gluing, rigid screw locking, or one-piece injection molding. This type of connection structure has significant drawbacks in practical applications: Firstly, when the connecting bracket is damaged due to accidental impact or long-term wear, because the earcup and bracket cannot be separated, the user needs to replace the entire headphone or a large component including the earcup, leading to a significant increase in repair costs and wasting resources on undamaged parts like the earcup. Secondly, the fixed connection structure cannot meet users' personalized needs for adjusting the appearance and function of the headphones. For example, users cannot easily change the connecting bracket to different colors or materials according to their preferences, or find dedicated brackets to adapt to different wearing angles, limiting the expansion of the headphone's usage scenarios. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an earphone structure and earphone with a detachable connecting bracket that allows for convenient and quick assembly and disassembly of the connecting bracket.

[0005] The purpose of this disclosure is achieved through the following technical solution: A headphone structure with a detachable connecting bracket, characterized in that it includes a headband, a first connecting bracket, a second connecting bracket, a first ear cover, and a second ear cover; a first end of the headband is fixedly connected to one end of the first connecting bracket, and a second end of the headband is fixedly connected to the other end of the second connecting bracket; The first connecting bracket has a first silicone protrusion at one end, and the outer peripheral wall of the first ear cover has a first connecting hole, the first silicone protrusion being detachably connected to the first connecting hole; the second connecting bracket has a second silicone protrusion at the other end, the second silicone protrusion being detachably connected to the second connecting hole.

[0006] In one embodiment, both the first silicone element and the second silicone element are elastic elements, the first silicone element is pluggable to the first connecting hole, and the second silicone element is pluggable to the second connecting hole.

[0007] In one embodiment, there are two first silicone parts and two first connecting holes. One first silicone part is disposed opposite to the other first silicone part, and one first silicone part is plugged into and connected to one first connecting hole.

[0008] In one embodiment, there are two second silicone parts and two second connecting holes. One second silicone part is disposed opposite to another first silicone part, and one second silicone part is pluggable to one of the second connecting holes.

[0009] In one embodiment, the inner cavity of the first ear cover is provided with a first limiting portion, the first limiting portion is disposed adjacent to the first connecting hole, and the first silicone part is fitted with the side end of the first limiting portion; and / or, the inner cavity of the second ear cover is provided with a second limiting portion, the second limiting portion is disposed adjacent to the second connecting hole, and the second silicone part is fitted with the side end of the second limiting portion.

[0010] In one embodiment, the number of the first limiting portion is two, with one first limiting portion disposed opposite to the other; and / or, the number of the second limiting portion is two, with one second limiting portion disposed opposite to the other.

[0011] In one embodiment, the first silicone element is provided with a first elastic surface, which is disposed adjacent to the first limiting portion and abuts against the side end of the first limiting portion. And / or, the second silicone element is provided with a second elastic surface, the second elastic surface is disposed adjacent to the second limiting portion shown, and the second elastic surface abuts against the side end of the second limiting portion.

[0012] In one embodiment, the cross-sectional area of ​​the first elastic surface is equal to the cross-sectional area of ​​the first connecting hole, and the cross-sectional area of ​​the second elastic surface is equal to the cross-sectional area of ​​the second connecting hole.

[0013] An earphone includes an earphone structure with a detachable connecting bracket as described in any of the above embodiments.

[0014] Compared with the prior art, this disclosure has at least the following advantages: Compared to existing technologies, this invention achieves a tool-free, extremely simple quick-release structure through the interference fit between the first silicone component and the first connecting hole, and the second silicone component and the second connecting hole. This structure eliminates traditional screws, hinges, and other complex parts, simplifying the structure and reducing production costs. Simultaneously, the silicone material provides excellent damping and friction, ensuring stability after connection and preventing detachment due to shaking. Furthermore, the softness of silicone also provides cushioning and shock absorption, improving product durability and user experience. When the headband needs to be replaced, because the first and second connectors are detachably connected to the first and second connecting holes, the entire headphone device can be replaced without replacing the entire headphone. This avoids the need to replace both the first and second earcups simultaneously. Attached Figure Description

Detailed Implementation

[0018] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0020] 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.

[0021] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: like Figures 1 to 4 As shown, an embodiment of the headphone structure 10 with a detachable connecting bracket is characterized in that it includes a headband 100, a first connecting bracket 200, a second connecting bracket 300, a first ear cover 400, and a second ear cover 500; a first end of the headband 100 is fixedly connected to one end of the first connecting bracket 200, and a second end of the headband 100 is fixedly connected to the other end of the second connecting bracket 300. The first connecting bracket 200 has a first silicone part 210 protruding at the other end, and the first ear cover 400 has a first connecting hole 410 on its outer peripheral wall. The first silicone part 210 is detachably connected to the first connecting hole 410. The second connecting bracket 300 has a second silicone part 310 protruding at the other end, and the second silicone part 310 is detachably connected to the second connecting hole 510.

[0022] In this embodiment, the first connecting bracket 200 is fixedly connected to the first end of the headband 100, and the second connecting bracket 300 is fixedly connected to the second end of the headband 100, thereby connecting the first connecting bracket 200 and the second connecting bracket 300 to both ends of the headband 100. The other end of the first connecting bracket 200 extends away from the headband 100 and is integrally formed or fixedly connected to a first silicone element 210. Similarly, the other end of the second connecting bracket 300 is also integrally formed or fixedly connected to a second silicone element 310. The first silicone element 210 and the second silicone element 310 are preferably made of soft elastic silicone material, and their shape is preferably cylindrical or frustum-shaped. Corresponding to the first silicone element 210, a first connecting hole 410 is provided on the outer peripheral wall (i.e., side) of the first ear cover 400. The shape and size of the first connecting hole 410 are adapted to the outer dimensions of the first silicone element 210. More specifically, the diameter of the first connecting hole 410 is slightly smaller than the maximum outer diameter of the first silicone element 210, so that the first silicone element 210 can be inserted into and tightly engaged in the first connecting hole 410 in an interference fit. Similarly, a second connecting hole 510 is provided on the outer peripheral wall of the second ear cover 500 for detachable connection with the second silicone element 310 on the second connecting bracket 300 in the same manner.

[0023] During the assembly process, the user simply aligns the first silicone piece 210 on the first connecting bracket 200 with the first connecting hole 410 on the first ear cover 400, and then applies a certain pressure to push it into the hole. Due to the good elastic deformation capability of the silicone material, the first silicone piece 210 will be slightly deformed under pressure during insertion, and after fully entering the first connecting hole 410, it will return to its original shape through its own elasticity, thus firmly locking into the hole and achieving a reliable connection. The connection method on the second side is exactly the same.

[0024] During disassembly, the user only needs to hold the ear cover and the first connecting bracket 200 and the second connecting bracket 300, and apply opposite pulling forces to pull the first silicone component 210 or the second silicone component 310 out of the corresponding first connecting hole 410 or second connecting hole 510. The elasticity of the first silicone component 210 and the second silicone component 310 ensures that the disassembly process will not cause permanent damage to the parts, and repeated disassembly and assembly are possible.

[0025] Compared with existing technologies, this embodiment achieves a quick-release structure that requires no tools and is extremely easy to operate through the interference fit between the first silicone part 210 and the first connecting hole 410, and the second silicone part 310 and the second connecting hole 510. This structure eliminates traditional screws, shafts, and other complex parts, simplifying the structure and reducing production costs. Simultaneously, the silicone material provides good damping and friction, ensuring stability after connection and preventing it from easily detaching due to shaking. Furthermore, the softness of silicone also plays a role in cushioning and shock absorption, improving product durability and user experience. When the headband 100 needs to be replaced, because the first and second connectors are detachably connected to the first connecting hole 410 and the second connecting hole 510, it is possible to replace the entire headphone device without replacing the entire headphone device. The first and second connectors can be replaced according to user needs, avoiding the need to replace the first ear cover 400 and the second ear cover 500 simultaneously.

[0026] See Figure 2 , Figure 3 and Figure 4 Furthermore, both the first silicone element 210 and the second silicone element 310 are elastic elements. The first silicone element 210 is pluggable and detachable connected to the first connecting hole 410, and the second silicone element 310 is pluggable and detachable connected to the second connecting hole 510. It can be understood that by making the first silicone element 210 and the second silicone element 310 elastic elements, the first silicone element 210 can be elastically inserted into the first connecting hole 410, and the second silicone element 310 can be correspondingly elastically inserted into the second connecting hole 510. This facilitates a smoother and more detachable connection of the first silicone element 210 and the second silicone element 310 to the first connecting hole 410 and the second connecting hole 510. See Figure 2 , Figure 3 and Figure 4 In one embodiment, there are two first silicone parts 210 and two first connecting holes 410. One first silicone part 210 is positioned opposite to the other, and one first silicone part 210 is plugged into one first connecting hole 410. It can be understood that compared to a single-point connection of a single first silicone part 210, two oppositely positioned first silicone parts 210 can form a bidirectional limiting mechanism, effectively restricting the rotational freedom of the first ear cover 400 around the connecting axis. This prevents the ear cover from deflecting due to head shaking or accidental contact during use, thus affecting the fit. Simultaneously, the two-point force distribution can disperse the weight load of the ear cover, reducing the deformation pressure of a single silicone part, lowering the risk of fatigue aging of the silicone part due to localized stress concentration after long-term use, and further extending the service life of the connection structure.

[0027] See Figure 2 , Figure 3 and Figure 4 In one embodiment, there are two second silicone pieces 310 and two second connecting holes 510. One second silicone piece 310 is positioned opposite to the other first silicone piece 210, and one second silicone piece is plugged into one of the second connecting holes 510. It can be understood that the second ear cover 500 adopts the same dual-point connection design as the first ear cover 400, together forming a stable and symmetrical connection system. The two oppositely positioned second silicone pieces 310, in conjunction with the two second connecting holes 510, provide balanced support and circumferential restraint for the second ear cover 500. This symmetrical dual-point locking structure effectively prevents any unintended rotation or swaying of the second ear cover 500 relative to the second connecting bracket 300 during use, ensuring the consistency, stability, and comfort of the earphone's wearing posture.

[0028] See Figure 2 and Figure 3 Furthermore, the inner cavity of the first ear cover 400 is provided with a first limiting portion 420, which is disposed adjacent to the first connecting hole 410. The first silicone member 210 is fitted with the side end of the first limiting portion 420. It can be understood that by providing a first limiting portion 420 in the inner cavity of the first ear cover 400, and by providing a first limiting portion 420 adjacent to the first connecting hole 410, when the first silicone member 210 is inserted into the first connecting hole 410, the first silicone member 210 is fitted with the side end of the first limiting portion 420, thus limiting the insertion depth of the first silicone member 210 and preventing the first silicone member 210 from extending excessively into the inner cavity of the first ear cover 400.

[0029] See Figure 2 and Figure 4 In another embodiment, the inner cavity of the second ear cover 500 is provided with a second limiting portion 520, which is disposed adjacent to the second connecting hole 510, and the second silicone member 310 is fitted with the side end of the second limiting portion 520. Similarly, by providing the second limiting portion 520 adjacent to the second connecting hole 510 in the inner cavity of the second ear cover 500, a precise mechanical stop is provided for the insertion depth of the second silicone member 310. When the user inserts the second silicone member 310 into the second connecting hole 510, the end or side wall of the second silicone member 310 will contact and fit with the side end of the second limiting portion 520, thereby being reliably restricted to the predetermined installation position. This structure effectively prevents the risk of excessive deformation of the second silicone member 310, pressure on the speaker unit or other internal components in the inner cavity of the second ear cover 500 due to excessive insertion, or even the connection structure being "locked" and difficult to disassemble.

[0030] See Figure 2 and Figure 3Furthermore, there are two first limiting portions 420, with one first limiting portion 420 positioned opposite to the other. It can be understood that when there are two first silicone parts 210 positioned opposite each other, setting two first limiting portions 420 in a relative arrangement allows for a precise one-to-one correspondence and fit with the dual silicone part structure. After each first silicone part 210 is inserted into its corresponding first connecting hole 410, its end or inner sidewall can fit against the side end of a first limiting portion 420. This paired limiting structure provides balanced and independent axial stops for the two first silicone parts 210, ensuring consistent insertion depth at each connection point in the dual-point connection. This guarantees the parallelism and stability of the assembly between the first ear cover 400 and the first connecting bracket 200, avoiding ear cover tilting or uneven force due to excessive interference on one side.

[0031] See Figure 2 and Figure 4 In another embodiment, there are two second limiting portions 520, one second limiting portion 520 and the other second limiting portion 520. It can be understood that when there are two second silicone pieces 310 arranged opposite each other, configuring two second limiting portions 520 in a relative arrangement allows for precise matching and coordination with the double silicone piece structure on the second ear cover 500 side. After each second silicone piece 310 is inserted into its corresponding second connecting hole 510, its end or inner wall can be securely fitted with the side end of a second limiting portion 520. This symmetrical paired limiting structure provides balanced and reliable axial mechanical stops for the two second silicone pieces 310, ensuring the assembly consistency and positional accuracy of the second ear cover 500 and the second connecting bracket 300 in a two-point connection state, effectively preventing ear cover assembly misalignment or stress concentration caused by unilateral insertion depth deviation.

[0032] See Figure 2 and Figure 3In one embodiment, the first silicone element 210 is provided with a first elastic surface 2110, which is disposed adjacent to the first limiting portion 420 and abuts against the side end of the first limiting portion 420. It can be understood that by providing a dedicated first elastic surface 2110 at the end of the first silicone element 210 and configuring it to elastically abut against the side end of the first limiting portion 420, a contact interface with buffering and adaptive functions is created. This elastic surface is made of silicone material itself and undergoes controllable elastic deformation when compressed by the first limiting portion 420. This design offers several advantages: First, the rebound force generated by elastic deformation ensures a tight contact between the silicone part and the limiting part, eliminating assembly gaps that may arise due to manufacturing tolerances and enhancing the stability of the connection. Second, the soft, elastic contact effectively avoids hard collisions and friction, reducing wear on the limiting part and the silicone part itself during long-term disassembly and assembly, thus improving the durability of the parts. Finally, this elastic support can also absorb some of the vibration and impact from the ear cover, further optimizing the product's shock absorption performance.

[0033] See Figure 2 and Figure 4 In another embodiment, the second silicone element 310 is provided with a second elastic surface 3110, which is disposed adjacent to the second limiting portion 520 and abuts against the side end of the second limiting portion 520. It can be understood that the second elastic surface 3110 is a portion of the end face or circumferential sidewall of the second silicone element 310 away from the second connecting bracket 300. By performing arc chamfering, micro-convex surface molding, or thin-wall design on the end of the second silicone element 310, it possesses a superior elastic deformation capability compared to the main body of the silicone element. When the second silicone element 310 is inserted into the second connecting hole 510 and contacts the second limiting portion 520, the second elastic surface 3110, as the primary contact point, will undergo slight and controllable elastic contraction under the compression of the limiting portion, forming a flexible abutment state.

[0034] See Figure 2 , Figure 3 and Figure 4The cross-sectional area of ​​the first elastic surface 2110 is equal to the cross-sectional area of ​​the first connecting hole 410, and the cross-sectional area of ​​the second elastic surface 3110 is equal to the cross-sectional area of ​​the second connecting hole 510. It can be understood that by setting the cross-sectional area of ​​the elastic surface to be equal to the cross-sectional area of ​​the corresponding connecting hole, maximum matching of the contact interface is achieved. When the first silicone element 210 is inserted into the first connecting hole 410 and the first elastic surface 2110 abuts against the first limiting part 420, the equal cross-sectional areas ensure that the first elastic surface 2110 can completely cover and seal the opening of the first connecting hole 410. Similarly, when the second silicone element 310 is inserted into the second connecting hole 510 and the second elastic surface 3110 abuts against the second limiting part 520, external impurities such as dust and moisture are effectively prevented from entering the interior of the first ear cover 400 or the second ear cover 500 through the connection gap, thus improving the product's dustproof and moisture-proof performance. At the same time, this equal area fit ensures that the friction generated by the interference fit is evenly distributed across the entire contact surface, avoiding stress concentration. This not only guarantees a strong connection but also makes the insertion and removal feel smoother and more consistent.

[0035] This application also provides an earphone, including an earphone structure 10 with a detachable connecting bracket as described in any of the above embodiments.

[0036] Compared with the prior art, this disclosure has at least the following advantages: Compared with existing technologies, the interference fit between the first silicone component 210 and the first connecting hole 410, and the second silicone component 310 and the second connecting hole 510, achieves a quick-release structure that requires no tools and is extremely easy to operate. This structure eliminates traditional screws, shafts, and other complex parts, simplifying the structure and reducing production costs. Simultaneously, the silicone material provides good damping and friction, ensuring stability after connection and preventing it from easily detaching due to shaking. Furthermore, the softness of silicone also plays a role in cushioning and shock absorption, improving product durability and user experience. When the headband 100 needs to be replaced, because the first and second connectors are detachably connected to the first connecting hole 410 and the second connecting hole 510, it is possible to replace the entire headphone device without replacing the entire headphone. The first and second connectors can be replaced according to user needs, avoiding the need to replace the first ear cover 400 and the second ear cover 500 simultaneously.

[0037] 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.
