Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, specifically to an over-ear headphone. Background Technology

[0002] With the rapid advancement of audio equipment technology, over-ear headphones, as a key sound output tool, are widely used in everyday entertainment, office work, and professional settings. However, most current over-ear headphones use a fixed earcup design, lacking flexible adjustment capabilities and unable to adapt to the user's head shape and ear position. This rigid connection often results in an insufficiently snug fit during actual wear, easily causing ear pressure and discomfort, and even leading to problems such as sound leakage or reduced noise cancellation. Especially for users who need to wear headphones for extended periods, the fixed earcup angle increases the burden on the auricle, reduces comfort, and consequently affects the overall listening experience.

[0042] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0043] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0044] Over-ear headphones are frequently used in people's daily lives, work, study, and entertainment. Over-ear headphones typically consist of a headphone frame and two earcups. The headphone frame is connected to two earcups at each end, and each earcup is fitted with an earcup. When using them, the headphone frame is usually worn on the head, and the earcups are placed over the ears.

[0045] Most existing over-ear headphones have non-rotating and non-swinging earcups, making them unsuitable for different head shapes and resulting in poor wearing comfort. They are also prone to sound leakage or isolation, leading to subpar performance. Existing rotatable over-ear headphones have the rotating mechanism located on the outside of the earcup, resulting in a larger overall footprint.

[0046] This embodiment provides an over-ear headphone that allows the earcups to rotate and swing to fit different users, improving the airtightness of the headphones and the comfort of the user. At the same time, the structure for rotating and swinging the over-ear headphone is set inside the earcups, which can reduce the space occupied. In addition, the over-ear headphone can also simplify the assembly of the earcups and headphone frame, improve production efficiency, assembly stability and reliability, and improve the problem of separation of the headphone frame and earcups due to pulling.

[0047] Reference Figure 1 , Figure 2 , Figure 3As shown, in this embodiment, the over-ear headphone 010 includes an earcup 100, a rotating assembly 200, a headphone frame 300, and a limiting member 400. The rotating assembly 200 is disposed inside the earcup 100, and the headphone frame 300 is rotatably inserted into the rotating assembly 200. The limiting member 400 is disposed on the rotating assembly 200 and cooperates with the headphone frame 300 to lock the headphone frame 300 and the rotating assembly 200 in the inserted state and limit the rotation angle of the headphone frame 300. This completes the assembly of the headphone frame 300, effectively simplifies the assembly of the over-ear headphone 010, and helps to improve production efficiency. At the same time, it can also limit the rotation angle of the headphone frame 300 relative to the rotating assembly 200, which can avoid the problem of the cable inside the over-ear headphone 010 breaking due to excessive rotation.

[0048] Reference Figure 3 , Figure 4 and Figure 5 As shown, the outer surface of the rotating assembly 200 is provided with a limiting groove 211 extending in the circumferential direction. After the headphone holder 300 is rotatably inserted into the rotating assembly 200, the limiting member 400 passes through the limiting groove 211 of the rotating assembly 200 and is fixedly connected to the headphone holder 300. Thus, through the cooperation of the limiting member 400 and the limiting groove 211, the headphone holder 300 is locked in the inserted state with the rotating assembly 200 (i.e., the relative position of the headphone holder 300 and the rotating assembly 200 is locked in the insertion direction), ensuring the stability and reliability of the insertion of the headphone holder 300 and the rotating assembly 200, and preventing the headphone holder 300 from separating from the rotating assembly 200. Meanwhile, since the limiting groove 211 extends circumferentially on the outer surface of the rotating assembly 200, when the headphone frame 300 rotates relative to the rotating assembly 200, the limiting member 400 can rotate within the limiting groove 211 due to the fixed connection between the headphone frame 300 and the limiting member 400. The limiting member 400 stops rotating when it reaches both ends of the limiting groove 211. Therefore, the length of the limiting groove 211 determines the rotation angle of the headphone frame 300. Thus, the over-ear headphones of this embodiment, by providing a circumferentially extending limiting groove 211 on the outer surface of the rotating assembly and fixing the limiting member 400 through the limiting groove 211 to the headphone frame 300, not only achieve axial locking of the headphone frame 300 but also control the rotation angle of the headphone frame 300. This simplifies the assembly of the rotating assembly 200 and the headphone frame 300, improves production efficiency, and enhances assembly stability and reliability.

[0049] Reference Figure 1As shown, the headphone frame 300 includes a headband 310 and two rotating arms 320, with the two ends of the headband 310 respectively connected to the two rotating arms 320. The over-ear headphones 010 include two earcups 100 and two rotating components 200, with the two rotating components 200 and the two earcups 100 arranged in a one-to-one correspondence, and the two rotating arms 320 are connected to the two earcups 100 in a one-to-one correspondence through the two rotating components 200.

[0050] The following will describe in detail a set of rotating support arms 320, rotating components 200 and earcups 100. The structure and working principle of other speaker components of the over-ear headphones 010 are similar to the related technologies and will not be specifically limited here.

[0051] Reference Figures 3-5 As shown, the rotating assembly 200 includes a rotating member 210, which is disposed on the earcup 100. A rotating support arm 320 is rotatably inserted into the rotating member 210. A limiting member 400 is disposed on the rotating member 210 and cooperates with the rotating support arm 320 to lock the rotating support arm 320 and the rotating member 210 in the inserted state. This arrangement ensures the ease of operation of the rotating support arm 320 in assembling with the rotating member 210, that is, ensures the ease of operation of connecting the rotating support arm 320 to the earcup 100 via the rotating member 210.

[0052] Specifically, refer to Figure 5 and Figure 11 As shown, the rotating component 210 includes a limiting groove 211 and a mounting hole 212. The mounting hole 212 extends through the axis of the rotating component 210. The limiting groove 211 is disposed on the outer surface of the rotating component 210 and extends in the circumferential direction (i.e., it is disposed around the axis of the rotating component 210). The limiting groove 211 is laterally connected to the mounting hole 212. The rotating support arm 320 is rotatably inserted into the mounting hole 212. The limiting component 400 is inserted into the limiting groove 211, passes through the limiting groove 211, and extends into the mounting hole 212 to be fixedly connected to the rotating support arm 320. With this configuration, the rotating arm 320 can be securely locked in the position where it is inserted into the rotating component 210 by the limiting member 400. Moreover, during assembly, the rotating arm 320 can be inserted into the mounting hole 212 of the rotating component 210, and then the limiting member 400 can be installed in the limiting groove 211 of the rotating component 210 and fixedly connected to the rotating arm 320. This ensures the ease of operation of assembling the rotating arm 320 and the rotating component 210, thereby improving assembly efficiency.

[0053] To ensure that the limiting component 400 reliably mates with the headphone holder 300, refer to Figure 5The headphone holder 300 is provided with a positioning hole 321. Specifically, the rotating arm 320 is provided with a positioning hole 321, which is located on the outer surface of the rotating arm 320. When the rotating arm 320 is inserted into the mounting hole 212 of the rotating component 210, the positioning hole 321 can be exposed from the limiting groove 211. The limiting member 400 passes through the limiting groove 211 of the rotating component 200 and is fixedly connected to the positioning hole 321. Thus, the headphone holder 300 is locked in the inserted state with the rotating component 200 through the cooperation of the limiting member 400 and the limiting groove 211, ensuring the stability and reliability of the insertion between the headphone holder 300 and the rotating component 200, and preventing the headphone holder 300 from separating from the rotating component 200. At the same time, by limiting the angle at which the limiting member 400 can swing within the limiting groove 211, the rotation angle of the rotating arm 320 relative to the rotating member 210 is limited, which also limits the relative rotation angle of the headphone frame 300 and the earcups 100, thus preventing the cable inside the earcup headphones 010 from breaking due to excessive rotation.

[0054] In this embodiment, refer to Figure 12 As shown, the mounting hole 212 includes a first hole 2121 and a second hole 2122 that are axially connected. The diameter of the first hole 2121 is larger than the diameter of the second hole 2122, forming a stepped structure between them. The size of the first hole 2121 is adapted to the size of the rotating support arm 320, allowing the rotating support arm 320 to be inserted into and rotated within it. The limiting groove 211 is radially connected to the first hole 2121. The distance between the limiting groove 211 and the mating surface of the first hole 2121 and the second hole 2122 is equal to the distance from the positioning hole 321 to the end of the rotating support arm 320. This ensures that when the rotating support arm 320 is inserted into the first hole 2121 and abuts against the mating surface (i.e., the stepped surface) (i.e., inserted into place), the positioning hole 321 and the limiting groove 211 are directly opposite each other. This allows the limiting member 400 to pass through the limiting groove 211 and be fixedly connected to the positioning hole 321. In this embodiment, the mounting hole 212 is designed so that it is not necessary to manually observe whether the rotating arm 320 is properly inserted during assembly, which simplifies assembly and improves production efficiency. The first hole 2121 facilitates the passage of the earmuff 100 cable into the interior of the rotating arm 320.

[0055] In other embodiments, the mounting hole 212 is set as a through hole of the same diameter. During assembly, the position of the positioning hole 321 is observed from above the limiting groove 211 to determine whether the rotating arm 320 is inserted into place.

[0056] In this embodiment, at least a portion of the outer surface of the rotating member 210 is an arc surface, and the limiting groove 211 is disposed on the arc surface and distributed around the outer circumference of the rotating member. Thus, the limiting groove 211 is set as an arc groove, which can more accurately control the rotation angle of the rotating arm 320. The position and length of the limiting groove 211 are set according to requirements.

[0057] The limiting component 400 includes a positioning pin, which can pass through the limiting groove 211 and connect to the positioning hole 321, thereby locking the headphone frame 300 (i.e., the rotating arm 320) and the rotating component 200 (i.e., the rotating component 210) in the axial position, that is, they cannot move relative to each other in the axial position. This not only improves assembly efficiency, but also improves the reliability of the assembly.

[0058] The limiting member 400 can also be a bolt or screw, and the positioning hole 321 can be a threaded hole. After passing through the limiting groove 211, the limiting member 400 is threaded into the positioning hole 321, thereby locking the headphone bracket 300 (i.e., the rotating arm 320) and the rotating component 200 (i.e., the rotating component 210) in the plugged state. This connection method is simple and easy to assemble.

[0059] The manner in which the rotating component 210 is positioned on the earcup 100 can be selected as needed. (Refer to...) Figure 6 and Figure 7 As shown, the rotating component 210 is rotatably mounted on the earcup 100, and the rotation axis of the rotating component 210 forms an angle with the rotation axis of the rotating support arm 320. Since the rotating support arm 320 is rotatably inserted into the rotating component 210, the rotating component 210 can rotate relative to the earcup 100 about the rotation axis of the rotating component 210, which is the subsequent up-and-down swing, thereby adapting to different users' head contours.

[0060] Reference Figure 5 and Figure 11 As shown, the rotating component 210 is connected to two rotating shafts 213, which are respectively disposed on both sides of the rotating component 210, and the two rotating shafts 213 are coaxially distributed. After the rotating component 210 is placed inside the earcup 100, it can rotate about the center line of the two rotating shafts 213 as the axis of rotation.

[0061] Reference Figure 3 , Figure 5 , Figure 9 and Figure 11As shown, the rotating assembly 200 includes a mounting bracket 220, which is located above the rotating member 210 and extends to both sides of the rotating member 210 to be connected to the earcups 100 respectively. A swing space is formed between the mounting bracket 220 and the rotating member 210 to limit the upward swing angle of the rotating member 210; a support plate 105 is provided on the earcup 100, located below the rotating member 210, to limit the downward swing angle of the rotating member 210.

[0062] The mounting bracket 220 has shaft holes on both sides and between it and the earcup 100. The two rotating shafts 213 of the rotating component 210 are inserted into the two shaft holes one-to-one. This arrangement ensures that the rotating component 210 is stably rotatably connected to the earcup 100 via the mounting bracket 220, allowing for more flexible relative movement between the earcup 100 and the rotating support arm 320 connected by the rotating component 210. This facilitates the user in adjusting the relative position of the headphone frame 300 and the earcup 100 as needed, improving ease of use.

[0063] The connection methods between the mounting bracket 220 and the earcup 100 include, but are not limited to, snap-fit, adhesive, or fasteners such as bolts and screws, and are not specifically limited here.

[0064] It should be noted that the angle between the rotation axis of the rotating component 210 and the rotation axis of the rotating support arm 320 can be 90°, 88°, 93°, etc., and no specific limitation is made here.

[0065] In one embodiment, reference is made to... Figure 3 and Figure 5 As shown, the mounting bracket 220 includes a mounting body 221 and two connecting plates 222, which are disposed on both sides of the mounting body 221. The mounting body 221 covers the rotating component 210, forming a swing space between them to limit the upward rotation angle of the rotating component 210. The two connecting plates 222 are used to connect to the earcups 100. The size and shape of the swing space are determined by the shape of the side of the mounting body 221 facing the earcups 100. To reduce noise and wear on the rotating support arm 320, a buffer, such as a rubber pad or latex pad, can be installed on the side of the mounting body 221 facing the earcups 100. The connection methods between the two connecting plates 222 and the earcups 100 include, but are not limited to, snap-fitting, bonding, and fasteners such as bolts and screws, etc., and are not specifically limited here.

[0066] In this configuration, after the mounting bracket 220 is connected to the earcup 100, axial holes are formed between the two sides of the mounting body 221 and the earcup 100. Specifically, refer to... Figure 5 and Figure 13The mounting body 221 has rotating grooves 223 on both sides facing the earcup 100. The earcup 100 has two bearing grooves 102. After the mounting bracket 220 is connected to the earcup 100, the two rotating grooves 223 and the two bearing grooves 102 form shaft holes corresponding to each other vertically. The rotating grooves 223 and the bearing grooves 102 are each less than or equal to semicircular grooves, and the shaft holes formed by their vertical correspondence can be complete circular holes or circular holes with lateral openings. The rotating shaft 213 rotates between the rotating grooves 223 and the bearing grooves 102, thereby restricting the sliding or movement of the rotating component 210. The rotating grooves 223 can be formed by upward-facing recesses on the bottom surfaces of both sides of the mounting body 221, and the bearing grooves 102 can be formed by the arc-shaped top surfaces of reinforcing ribs or the like inside the earcup 100.

[0067] Optionally, refer to Figure 3 and Figure 5 Two connecting plates 222 each have connecting holes 2221. The earcup 100 is connected to a connecting post 104, which corresponds to the connecting hole 2221. A connector 2222 is inserted into the connecting hole 2221 and connected to the connecting post 104, thereby fixing the mounting bracket 220 to the earcup 100. The two connecting posts 104 are located outside the two bearing grooves 102. The connecting posts 104 are threaded, and the connector can be a screw or similar component.

[0068] To ensure the comfort of the over-ear headphones 010 during use, and to ensure that the earcups 100 fit the ear more snugly; continue to refer to Figure 3 and Figure 5 The rotating assembly 200 also includes an elastic element 230, which is disposed between the rotating member 210 and the earcup 100. When the rotating member 210 rotates, it can compress or stretch the elastic element 230. When the force driving the rotating member 210 to rotate is removed, the rotating member 210 can return to its original position under the elastic action of the elastic element 230. It should be noted that the elastic element 230 includes, but is not limited to, springs and elastic sleeves. The connection methods between the two ends of the elastic element 230 and the earcup 100 and the rotating member 210 include, but are not limited to, abutment, snap-fit, and adhesive.

[0069] The way the elastic element 230 is disposed between the earcup 100 and the rotating member 210 can be selected as needed; in the embodiment of the mounting bracket 220 described above, the rotating member 210 is provided with a positioning structure 214, referring to... Figure 3 and Figure 5 As shown. The positioning structure 214 is disposed on the side of the limiting groove 211 near the inside of the earcup 100. One end of the elastic element 230 abuts against or connects to the positioning structure 214, and the other end of the elastic element 230 is connected to the earcup 100.

[0070] Reference Figure 5The elastic element 230 includes two elastic portions 231 and a connecting portion 232, with the two elastic portions 231 respectively connected to both ends of the connecting portion 232. When the elastic element 230 is assembled on the rotating member 210, the connecting portion 232 abuts against the positioning structure 214, and both elastic portions 231 are located on the outside of the rotating member 210. The bottom ends of the two elastic portions 231 are connected to the earcup 100. This structure makes the restoring force generated by the elastic element 230 balanced and large, which can stably restore the rotating member 210. Preferably, the elastic portion 231 can be a spring with a hook at the bottom end; the earcup 100 is provided with a corresponding hanging hole, so that the elastic portion 231 can be connected to the earcup 100 through the hook and the hanging hole.

[0071] Positioning structure 214 can be configured as needed; please refer to... Figure 3 and Figure 5 In this embodiment, the positioning structure 214 is a groove disposed above the rotating member 210. The groove is disposed outside the limiting groove 211. Preferably, the groove is not in communication with the mounting hole 212. The connecting part 232 is disposed in the groove and abuts against the groove wall. In other embodiments, the positioning structure 214 is a protrusion disposed above the rotating member 210, and the connecting part 232 abuts against the side of the rotating member 210 where the protrusion faces the limiting groove 211. During the reset process, it abuts against the protrusion, which can prevent the connecting part 232 from separating from the rotating member 210.

[0072] In this other embodiment, refer to Figure 8 , Figure 9 , Figure 10 and Figure 11 Compared to the above embodiment, the rotating component 210 is further provided with an assembly hole 215, and the mounting bracket 220 is further provided with a fixing hole 224. After the mounting bracket 220 is connected to the earcup 100, the fixing hole 224 and the assembly hole 215 are arranged vertically and vertically respectively. The rotating assembly 200 also includes a fastener 240, which passes through the fixing hole 224 and is inserted into the assembly hole 215 and connected to the earcup 100. An elastic element 230 is sleeved on the fastener 240, and both ends of the elastic element 230 are connected to the mounting bracket 220 and the rotating component 210 respectively. When the rotating component 210 rotates, the rotating component 210 can move relative to the mounting bracket 220 and compress or stretch the elastic element 230. When the force driving the rotating component 210 to rotate is removed, the rotating component 210 can return to its original position under the elastic action of the elastic element 230.

[0073] Specific reference Figure 9 and Figure 11As shown, mounting plates 216 are respectively provided on both sides of the rotating component 210. The mounting plates 216 are provided with assembly holes 215. The mounting body 221 also includes two extensions 225 on both sides. The two extensions 225 are arranged parallel above the two mounting plates 216. The extensions 225 are provided with fixing holes 224. Two mounting posts 103 are provided inside the ear cover 100. The two mounting posts 103 pass through the two assembly holes 215 respectively. Fasteners 240 pass through the fixing holes 224 and are connected to the mounting posts 103. Elastic elements 230 are sleeved on the outside of the mounting posts 103, and the two ends of the elastic elements 230 are connected to the mounting bracket 220 and the rotating component 210 respectively.

[0074] It should be noted that the elastic element 230 includes, but is not limited to, springs and elastic sleeves; the fastener 240 includes, but is not limited to, bolts and screws. The connection methods between the two ends of the elastic element 230 and the mounting bracket 220 and the rotating part 210 include, but are not limited to, abutment, snap-fit, and adhesive.

[0075] It should also be noted that, in order to avoid the fastener 240 interfering with the rotation of the rotating part 210, the mounting hole 215 can be set as an oblong hole, and the length extension direction of the mounting hole 215 forms an angle with the extension direction of the rotation axis of the rotating part 210, such as 90° or 91°; in this way, when the fastener 240 is inserted into the mounting hole 215, there is a certain clearance space, thereby ensuring that the rotation of the rotating part 210 will not be interfered with by the fastener 240.

[0076] In other embodiments, the mounting bracket 220 (i.e., the mounting body 221) can cover directly above the limiting groove 211, which can prevent the limiting member 400 from falling out and causing the earcup 100 to separate from the headphone frame when it becomes loose.

[0077] In this embodiment, refer to Figure 5 and Figure 11 As shown, the headphone holder 300 also includes a damping element 330, which is disposed on the rotating arm 320. The rotating member 210 is provided with a through mounting hole 212 along the axial direction. The rotating arm 320 is rotatably inserted into the mounting hole 212, and the damping element 330 is tightly fitted with the wall of the mounting hole 212 to form an interference fit. By providing the damping element 330, a damping effect is achieved when the rotating arm 320 and the rotating member 210 rotate relative to each other, which can reduce the rotation speed of the rotating arm 320 and extend its service life.

[0078] The damping element 330 can be selected as needed. In this embodiment, the damping element 330 is a rubber ring fitted onto the rotating arm 320; of course, in other embodiments, the damping element 330 can also be a silicone ring fitted onto the rotating arm 320. The number of damping elements 330 can be selected according to the actual situation, and is not limited to one or two.

[0079] To further ensure the ease of assembly of the 010 over-ear headphones; please refer to... Figure 5 and Figure 11 The earcup 100 has a through hole 101 through which the headphone frame 300 passes and is rotatably inserted into the rotating assembly 200. Specifically, the rotating arm 320 of the headphone frame 300 passes through the through hole 101 and is inserted into the rotating part 210 of the rotating assembly 200. Thus, when assembling the over-ear headphones 010, the rotating assembly 200 can be assembled onto the earcup 100 first, and then the rotating arm 320 can be passed through the through hole 101 and inserted into the rotating part 210, reducing the assembly complexity of the over-ear headphones 010.

[0080] The assembly process of the over-ear headphone 010 in this embodiment includes: first, assembling the rotating part 210, the mounting bracket 220, and the elastic element 230 into the earcup 100 in sequence; then, inserting the rotating arm 320 into the rotating part 210; and then, setting the limiting part 400 on the rotating part 210 and connecting it to the rotating arm 320.

[0081] In summary, the structure of the over-ear headphones 010 in this embodiment allows the earcups a certain degree of freedom of movement, enabling them to adapt to different users' head shapes and improving the fit and comfort for different users. At the same time, the assembly process of the over-ear headphones 010 is simplified, improving production efficiency; moreover, the assembly is stable and reliable, with excellent anti-pull performance.
