Description

Technical Field

[0001] This invention relates to the field of rotating structure technology, specifically to an earcup structure and headphones. Background Technology

[0002] Headphones are audio playback devices that are mounted on the head via a headband and have earcups covering (or pressing against) the ears. When using headphones, the earcups need to be adjusted to the correct angle to fit the face and improve the user experience.

[0003] In related technologies, the rotating structure at the earcups is often formed by the cooperation of multiple modules, resulting in a complex structure. During use, it is difficult to fully cover various angle requirements, thus failing to meet the wearing needs of various different head shapes. In addition, after removing the headphones, the rotating structure needs to be manually reset, and the accuracy of manual reset is poor, making it difficult for the earcups to return to their reference position, affecting the user experience. Summary of the Invention

[0004] In view of this, the present invention provides an earcup structure and headphones to solve the problems of the rotating structure of headphones being complex, difficult to fully cover various angle requirements, and requiring manual operation for resetting, which affects installation and use.

[0005] In a first aspect, the present invention provides an earmuff structure, comprising: a support, including a first base shaft and a second base shaft, the first base shaft and the second base shaft being spaced apart and intersecting; a fixing member, the first base shaft being rotatably connected to the fixing member; a rotating member, rotatably connected to the second base shaft, a gap being left between the fixing member and the rotating member; and an elastic member, disposed between the fixing member and the rotating member, and abutting against the wall surface opposite to the fixing member and the rotating member.

[0006] Beneficial effects: By setting up a support structure, which includes a first base axis and a second base axis, the first and second base axes are spaced apart and intersecting. The first base axis is connected to the fixed component, and the second base axis is connected to the rotating component. During use, the rotating component can rotate relative to the axis of the second base axis, i.e., the second axis, while the support and the rotating component can rotate relative to the axis of the first base axis, i.e., the first axis. This allows the rotating component to rotate relative to two different axes, thereby adjusting the three-dimensional angle of the earcup structure according to head shape differences, covering various angle requirements, and ensuring a stable fit in different head shapes and usage scenarios. The support structure is a rotating structure, which is simple and reliable. By setting up an elastic component, when the rotating component rotates, it tilts at a certain angle, reducing the distance between part of the rotating component and the fixed component, thereby compressing the elastic component. After the user removes the earcup structure, the elastic restoring force of the elastic component drives the fixed component and the rotating component to return to a state of parallel relative walls, eliminating the need for manual resetting and improving the user experience.

[0007] In one optional embodiment, the bracket further includes a fixed shaft, the two ends of which are fixed to the first base shaft and the second base shaft respectively; the fixed shaft has a third axis, and a plane perpendicular to the third axis is defined as a reference plane; the first base shaft has a first axis, the second base shaft has a second axis, and the projections of the first axis and the second axis onto the reference plane have an angle θ, satisfying 0° < θ < 180°.

[0008] Beneficial effects: The included angle θ is selected within the range of 0° < θ < 180°, which can adapt to a variety of different earmuff structures. Specifically, the included angle θ can be 90°, that is, the first base axis and the second base axis are set perpendicularly to each other, and the rotational motion of the two perpendicularly intersecting axes is combined into a universal spherical rotational motion.

[0009] In one alternative embodiment, the rotating member is adapted to rotate about the second axis, causing at least a portion of the rotating member to move toward the side closer to the fixed member to compress the elastic member, and / or; the bracket and the rotating member are adapted to rotate about the first axis, causing at least a portion of the rotating member to move toward the side closer to the fixed member to compress the elastic member.

[0010] In one optional embodiment, the fixing member has a first mounting hole through it, and one side of the fixing member has a first mounting groove recessed therein; the first mounting groove intersects and communicates with the first mounting hole, and the first base shaft is engaged with the first mounting groove; and / or, the rotating member has a second mounting hole through it, and one side of the rotating member has a second mounting groove recessed therein; the second mounting groove intersects and communicates with the second mounting hole, and the second base shaft is engaged with the second mounting groove.

[0011] Beneficial effects: By setting a matching first mounting hole and a first mounting groove, the first mounting groove and the first mounting hole intersect and communicate with each other. The first mounting hole is used to allow the first base shaft to pass through the fixing member, so as to ensure that the first base shaft can be smoothly engaged with the first mounting groove, ensuring a stable connection between the bracket and the fixing member. The installation method of the bracket and the fixing member is simple, replacing the complex structural design of the existing technology that requires the use of multiple screws and fasteners during installation. It is convenient to assemble, low in cost, and improves the service life and reliability of the ear cup structure.

[0012] In one alternative embodiment, the bracket further includes a first pin, which is coaxially connected to a first base shaft, with at least a portion of the first pin extending relative to the first base shaft and the extended end rotatably connected to a fixing member; and / or, the bracket further includes a second pin, which is coaxially connected to a second base shaft, with at least a portion of the second pin extending relative to the second base shaft and the extended end rotatably connected to the rotating member.

[0013] Beneficial effects: By setting a first pin, which is rotatably connected to the fixing part, the bracket and rotating part can rotate relative to the first base shaft. At the same time, the first pin and the first base shaft are coaxial, ensuring that the bracket and rotating part rotate stably around the first axis during rotation, thereby improving the stability of the overall structure.

[0014] In one optional embodiment, the fixing member includes a first base plate and a first protrusion; the first mounting hole penetrates the first base plate and the first protrusion, and the first mounting groove is disposed on the first protrusion; and / or, the rotating member includes a second base plate and a second protrusion; the second mounting hole penetrates the second base plate and the second protrusion, and the second mounting groove is disposed on the second protrusion.

[0015] Beneficial effects: The fastener includes a first substrate and a first protrusion. The first protrusion provides a structural basis for the setting of the first mounting groove. The first mounting groove is recessed on the side of the first protrusion away from the first substrate. At the same time, the first mounting hole passes through the first substrate and the first protrusion, ensuring that the first base shaft passes smoothly through the first mounting hole and cooperates with the first mounting groove at the first protrusion.

[0016] In one alternative embodiment, a portion of the second substrate protrudes toward the side near the fixing member to form a side edge, the side edge surrounding the second protrusion; the side edge is spaced apart from the fixing member.

[0017] Beneficial effects: By setting a side edge at the rotating part, it plays a preliminary role in protecting the second protrusion and the bracket in the circumferential direction. At the same time, the side edge is set at an interval from the fixed part to ensure that the fixed part and the rotating part do not interfere with each other when rotating. The structural design is reasonable and highly reliable.

[0018] In one optional embodiment, the elastic element is arranged around the periphery of the fixed shaft; the fixed element and the rotating element are respectively provided with annular grooves on their sides that are close to each other, and the two ends of the elastic element are respectively engaged with the annular grooves.

[0019] Beneficial effects: The elastic element is arranged around the fixed shaft. Through the reasonable configuration of the elastic element, the stable reset between the fixed element and the rotating element is effectively realized. When the fixed element and / or the rotating element rotates in any direction, at least part of the elastic body of the elastic element can be applied, thereby improving the reliability of the earmuff structure.

[0020] In one alternative embodiment, the earmuff structure further includes a flexible sleeve, which is spaced around the periphery of the elastic member; wherein the flexible sleeve is disposed between the fixed member and the rotating member, and abuts against the wall surface opposite to the fixed member and the rotating member.

[0021] Beneficial effects: The flexible sleeve is wrapped around the elastic component, which protects the elastic component and prevents dust and dirt from contaminating the elastic component and the support.

[0022] In one alternative embodiment, the fixing member has a recessed groove on the side near the rotating member; the flexible sleeve extends into the recess on the side away from the rotating member, and a gap is left between the flexible sleeve and the sidewall of the recess.

[0023] In a second aspect, the present invention provides an earphone, including an earcup structure as described in any of the preceding claims.

[0024] Since headphones include an earcup structure and have the same effect as earcups, they will not be described in detail here. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] The following is combined with Figures 1 to 19 The following describes embodiments of the present invention.

[0052] According to an embodiment of the present invention, an earmuff structure is provided, comprising: a support 1, including a first base shaft 11 and a second base shaft 12, the first base shaft 11 and the second base shaft 12 being spaced apart and intersecting; a fixing member 2, the first base shaft 11 being rotatably connected to the fixing member 2; a rotating member 3, being rotatably connected to the second base shaft 12, with a gap between the fixing member 2 and the rotating member 3; and an elastic member 4, disposed between the fixing member 2 and the rotating member 3, and abutting against the wall surface opposite to the fixing member 2 and the rotating member 3.

[0053] It should be noted that when the earcups are worn and used, the rotating part 3 is positioned closer to the user than the fixing part 2.

[0054] Specifically, since the first base shaft 11 and the second base shaft 12 are spaced apart and intersected, the first base shaft 11 is rotatably connected to the fixing member 2, and the rotating member 3 can rotate relative to the axis of the second base shaft 12, i.e., the second axis 121. The bracket 1 and the rotating member 3 can rotate relative to the axis of the first base shaft 11, i.e., the first axis 111. This allows the rotating member 3 to rotate relative to two different axes. That is, the rotating member 3 of the earmuff structure has the freedom to rotate in two directions around the first axis 111 and the second axis 121, thereby achieving the purpose of multi-angle adjustment of the rotating member 3. The earmuff structures are often used in pairs, with the two earmuff structures connected and the rotating members 3 arranged opposite each other. When the user puts the earmuff structure on the head, the head shape difference during the wearing process generates pressure on the earmuff structure, causing the rotating member 3 to move and rotate, thereby adjusting the three-dimensional angle of the earmuff structure. Since the rotating member 3 of the earmuff structure has the freedom to rotate in two directions around the first axis 111 and the second axis 121, it achieves the purpose of covering various angle requirements.

[0055] Specifically, when the fixing part 2 and the rotating part 3 rotate, the rotating part 3 tilts at a certain angle, causing part of the rotating part 3 to move closer to the fixing part 2, reducing the distance between part of the rotating part 3 and the fixing part 2, and thus compressing the elastic part 4. After the user removes the earcup structure, the elastic restoring force of the elastic part 4 drives the fixing part 2 and the rotating part 3 to return to a state where they are parallel to each other, eliminating the need for manual reset and improving the user experience.

[0056] Preferably, the first base axis 11 and the second base axis 12 can be set vertically in a three-dimensional misalignment, so that the first axis 111 and the second axis 121 are relatively perpendicular. The two perpendicularly intersecting rotational motions are combined into a universal spherical rotational motion. Specifically, the rotating member 3 can rotate around the second axis 121 in the forward or reverse direction to achieve a 360-degree spherical rotation of the rotating member, further improving the adaptability and comfort of the earmuff structure.

[0057] Preferably, the fixing component 2 can be the headphone arm, and the rotating component 3 can be the headphone back shell; the application of the bracket 1 and the elastic component 4 is not limited to the ear cup structure, but can also be applied to other structures that require omnidirectional rotation, such as robotic arm joints, camera gimbals, adjustable seat backs, etc.

[0058] In this embodiment, a bracket 1 is provided, which includes a first base shaft 11 and a second base shaft 12. The first base shaft 11 and the second base shaft 12 are spaced apart and intersected. The first base shaft 11 is connected to the fixing member 2, and the second base shaft 12 is connected to the rotating member 3. In use, the rotating member 3 can rotate relative to the axis of the second base shaft 12, i.e., the second axis 121. The bracket 1 and the rotating member 3 can rotate relative to the axis of the first base shaft 11, i.e., the first axis 111. This allows the rotating member 3 to rotate relative to two different axes, thereby enabling the adjustment of the earmuff knot according to head shape differences. The three-dimensional angle of the structure covers various angle requirements, ensuring a stable fit for different head shapes and usage scenarios. The bracket 1 is a rotating structure, which is simple and reliable. By setting the elastic element 4, when the rotating element 3 rotates, the rotating element 3 tilts at a certain angle, reducing the distance between part of the rotating element 3 and the fixed element 2, thereby compressing the elastic element 4. After the user removes the ear cup structure, the elastic restoring force of the elastic element 4 drives the fixed element 2 and the rotating element 3 to return to a state of parallelity with the opposite wall surface, eliminating the need for manual operation to reset and improving the user experience.

[0059] In some embodiments, combined with Figure 4 As shown, the bracket 1 also includes a fixed shaft 13, with its two ends fixed to a first base shaft 11 and a second base shaft 12, respectively. The fixed shaft 13 has a third axis 131, and a plane perpendicular to the third axis 131 is defined as a reference plane. The first base shaft 11 has a first axis 111, and the second base shaft 12 has a second axis 121. The projections of the first axis 111 and the second axis 121 onto the reference plane have an included angle θ, satisfying 0° < θ < 180°.

[0060] Specifically, one end of the fixed shaft 13 is connected to the first base shaft 11 at a predetermined angle, and the second end is connected to the second base shaft 12 at a predetermined angle. The first base shaft 11, the second base shaft 12, and the fixed shaft 13 constitute the bracket 1. The included angle θ is selected within the range of 0° < θ < 180°, preferably 90°, to adapt to various different earmuff structures. In this embodiment, the included angle θ is 90°, that is, the first base shaft 11 and the second base shaft 12 are perpendicularly intersecting. The rotational motion of the two perpendicularly intersecting axes is combined into a universal spherical rotational motion. Specifically, the rotating component 3 can rotate around the second axis 121 in the forward or reverse direction, and the bracket 1 and the fixed component 2 can rotate around the first axis 111 in the forward or reverse direction, realizing a 360-degree spherical rotation of the rotating component, further improving the adaptability and comfort of the earmuff structure.

[0061] In some embodiments, the rotating member 3 is adapted to rotate about a second axis 121, causing at least a portion of the rotating member 3 to move toward the side closer to the fixing member 2 to compress the elastic member 4, and / or; the bracket 1 and the rotating member 3 are adapted to rotate about a first axis 111, causing at least a portion of the rotating member 3 to move toward the side closer to the fixing member 2 to compress the elastic member 4.

[0062] In this embodiment, since the bracket 1 has a first base axis 11 and a second base axis 12, the rotating member 3 can rotate relative to the fixed member 2 around two different axes, thereby achieving the purpose of multi-angle adjustment of the rotating member 3. On this basis, due to the rotation, the rotating member 3 tilts at a certain angle, thereby causing part of the rotating member 3 to move closer to the fixed member 2, reducing the distance between part of the rotating member 3 and the fixed member 2, and thus compressing the elastic member 4. After the user removes the ear cup structure, under the action of the elastic restoring force of the elastic member 4, the fixed member 2 and the rotating member 3 are driven to return to the state of parallel relative wall surfaces.

[0063] In some embodiments, combined with Figure 6 As shown, the fastener 2 has a first mounting hole 21 through it, and a first mounting groove 22 is recessed on one side of the fastener 2; the first mounting groove 22 intersects and communicates with the first mounting hole 21, and the first base shaft 11 is engaged with the first mounting groove 22.

[0064] Specifically, in combination Figures 9 to 11 As shown, the first mounting groove 22 is recessed on the side of the fixing member 2 facing away from the rotating member 3. The shape of the first mounting hole 21 is adapted to the shape of the first base shaft 11, so that the first base shaft 11 passes through the fixing member 2. After the first base shaft 11 passes through the first mounting hole 21 for a certain distance, the bracket 1 or the fixing member 2 is rotated to align the first base shaft 11 with the first mounting groove 22. The shape of the first mounting groove 22 is adapted to the shape of the first base shaft 11, so that the first base shaft 11 and the first mounting groove 22 are engaged and fitted, so that the bracket 1 and the fixing member 2 are stably fitted together.

[0065] In this embodiment, by setting a first mounting hole 21 and a first mounting groove 22 that cooperate with each other, the first mounting groove 22 and the first mounting hole 21 intersect and communicate with each other. The first mounting hole 21 is used to allow the first base shaft 11 to pass through the fixing member 2, so as to ensure that the first base shaft 11 can be smoothly engaged with the first mounting groove 22, and to ensure a stable connection between the bracket 1 and the fixing member 2. The installation method of the bracket 1 and the fixing member 2 is simple, replacing the complex structural design of the prior art that requires the use of multiple screws and fasteners during installation. It is easy to assemble, low in cost, and improves the service life and reliability of the earmuff structure.

[0066] In some embodiments, combined with Figure 12As shown, the rotating part 3 has a second mounting hole 31 through it, and a second mounting groove 32 is recessed on one side of the rotating part 3; the second mounting groove 32 intersects and communicates with the second mounting hole 31, and the second base shaft 12 is engaged with the second mounting groove 32.

[0067] Specifically, in combination Figures 9 to 11 As shown, the second mounting groove 32 is recessed on the side of the rotating member 3 facing away from the rotating member 3. The shape of the second mounting hole 31 is adapted to the shape of the second base shaft 12, so that the second base shaft 12 passes through the rotating member 3. After the second base shaft 12 passes through the second mounting hole 31 for a certain distance, the bracket 1 or the rotating member 3 is rotated to align the second base shaft 12 with the second mounting groove 32. The shape of the second mounting groove 32 is adapted to the shape of the second base shaft 12, so that the second base shaft 12 and the second mounting groove 32 are engaged and fitted, so that the bracket 1 and the rotating member 3 are stably fitted together.

[0068] Preferably, the relative intersection angle between the first mounting hole 21 and the first mounting groove 22 is the same as the relative intersection angle between the second mounting hole 31 and the second mounting groove 32. In this embodiment, the first mounting hole 21 and the first mounting groove 22 may be perpendicular to each other, and the second mounting hole 31 and the second mounting groove 32 may be perpendicular to each other, thereby ensuring that after the bracket 1, the fixing member 2, and the rotating member 3 are engaged, the fixing member 2 and the rotating member 3 are aligned.

[0069] In some embodiments, combined with Figure 4 As shown, the bracket 1 also includes a first pin 14, which is coaxially connected to the first base shaft 11. At least a portion of the first pin 14 extends relative to the first base shaft 11, and the extended end of the first pin 14 is rotatably connected to the fixing member 2.

[0070] Specifically, the first pin 14 passes through the first base shaft 11 and is detachably connected to the first base shaft 11; the axis of the first pin 14 is collinear with the first axis 111; both ends of the first pin 14 extend out relative to the first base shaft 11, and the extended ends of the first pin 14 are rotatably connected to the fixing member 2; the fixing member 2 is provided with a first connecting hole 23 on the inner wall of the first mounting groove 22, and the extended ends of the first pin 14 are inserted into the first connecting hole 23 to form a rotating pair, so that the fixing member 2 is rotatably connected to the bracket 1.

[0071] In this embodiment, by setting a first pin 14, the first pin 14 is rotatably connected to the fixing member 2, thereby enabling the bracket 1 and the rotating member 3 to rotate relative to the first base shaft 11. At the same time, the first pin 14 and the first base shaft 11 are coaxially arranged to ensure that the bracket 1 and the rotating member 3 can stably rotate around the first axis 111 during rotation, thereby improving the stability of the overall structure.

[0072] Specifically, the bracket 1 also includes a second pin 15, which is coaxially connected to the second base shaft 12. At least a portion of the second pin 15 extends relative to the second base shaft 12, and the extended end of the second pin 15 is rotatably connected to the rotating member 3. The second pin 15 passes through the second base shaft 12, and the axis of the second pin 15 is collinear with the second axis 121. Both ends of the second pin 15 extend relative to the second base shaft 12, and the extended ends of the second pin 15 are rotatably connected to the rotating member 3. The rotating member 3 has a second connecting hole 33 on the inner wall of the second mounting groove 32. The extended end of the second pin 15 is inserted into the second connecting hole 33 to form a rotating pair, so that the rotating member 3 is rotatably connected to the bracket 1.

[0073] In some embodiments, combined with Figure 6 As shown, the fastener 2 includes a first substrate 24 and a first protrusion 25; a first mounting hole 21 passes through the first substrate 24 and the first protrusion 25, and a first mounting groove 22 is disposed on the first protrusion 25.

[0074] Specifically, the first protrusion 25 is disposed on the side of the first substrate 24 away from the rotating member 3, and the first mounting groove 22 is recessed on the side of the first protrusion 25 away from the first substrate 24; one end of the first connecting hole 23 passes through the outer wall of the first protrusion 25, and the other end passes through the inner wall of the first mounting groove 22. After the first base shaft 11 is installed in the first mounting groove 22, the first pin 14 can pass through the first connecting hole 23 to insert the first base shaft 11.

[0075] In this embodiment, the fastener 2 includes a first substrate 24 and a first protrusion 25. The first protrusion 25 provides a structural basis for the setting of the first mounting groove 22. The first mounting groove 22 is recessed on the side of the first protrusion 25 away from the first substrate 24. At the same time, the first mounting hole 21 penetrates the first substrate 24 and the first protrusion 25, ensuring that the first base shaft 11 passes smoothly through the first mounting hole 21 and cooperates with the first mounting groove 22 at the first protrusion 25.

[0076] Specifically, the rotating member 3 includes a second base plate 34 and a second protrusion 35; a second mounting hole 31 penetrates the second base plate 34 and the second protrusion 35, and a second mounting groove 32 is disposed on the second protrusion 35; the second protrusion 35 is disposed on the side of the second base plate 34 near the rotating member 3, and the second mounting groove 32 is recessed at the second protrusion 35; one end of the second connecting hole 33 penetrates the outer wall of the first protrusion 25, and the other end penetrates the inner wall of the second mounting groove 32. After the second base shaft 12 is installed in the second mounting groove 32, the second pin 15 can pass through the second connecting hole 33 to insert into the second base shaft 12.

[0077] In some embodiments, combined with Figure 12As shown, a portion of the second substrate 34 protrudes towards the side closer to the fixing member 2 to form a side edge 36, which surrounds the second protrusion 35; the side edge 36 is spaced apart from the fixing member 2.

[0078] Specifically, the side edge 36 is arranged around the second protrusion 35 to protect the second protrusion 35 and the bracket 1; the side edge 36 is spaced apart from the fixing member 2 to ensure that the fixing member 2 and the rotating member 3 do not interfere; the side edge 36 extends away from the fixing member 2 on one side and in a direction away from the fixing member 2. The earmuff structure also includes a speaker assembly 7, which is connected to the extended end of the side edge 36.

[0079] In this embodiment, by providing a side edge 36 at the rotating part 3, it serves to initially protect the second protrusion 35 and the bracket 1 in the circumferential direction. At the same time, the side edge 36 is spaced apart from the fixing part 2 to ensure that the fixing part 2 and the rotating part 3 do not interfere with each other when rotating. The structure is reasonably designed and highly reliable.

[0080] In some embodiments, combined with Figure 2 As shown, the elastic element 4 is arranged around the periphery of the fixed shaft 13; the fixed element 2 and the rotating element 3 are respectively provided with annular grooves 8 on their sides that are close to each other, and the two ends of the elastic element 4 are respectively engaged with the annular grooves 8.

[0081] Specifically, the elastic element 4 can be, but is not limited to, a spring. The elastic element 4 is arranged around the periphery of the fixed shaft 13, ensuring that at least a portion of the elastic body of the elastic element 4 is applied when the rotating member 3 rotates in any direction, thus guaranteeing the effective reset effect of the elastic element 4 on the fixed member 2 and the rotating member 3. Two annular grooves 8 are provided, and the two annular grooves 8 are respectively located at corresponding positions on the fixed member 2 and the rotating member 3. Both ends of the elastic element 4 are respectively engaged with the annular grooves 8; combined with... Figure 12 As shown, the annular groove 8 may be, but is not limited to, formed on the side of the second protrusion 35 near the fastener 2.

[0082] In this embodiment, the elastic element 4 is arranged around the periphery of the fixed shaft 13. Through the reasonable configuration of the elastic element 4, the stable reset between the fixed element 2 and the rotating element 3 is effectively realized. When the rotating element 3 rotates in any direction, it can ensure that at least part of the elastic body of the elastic element 4 is applied, thereby improving the reliability of the earmuff structure.

[0083] In some embodiments, combined with Figure 8 As shown, the earmuff structure also includes a flexible sleeve 5, which is spaced around the periphery of the elastic member 4; wherein, the flexible sleeve 5 is disposed between the fixed member 2 and the rotating member 3, and abuts against the wall surface opposite to the fixed member 2 and the rotating member 3.

[0084] Specifically, the flexible sleeve 5 has through holes, allowing it to surround the elastic element 4, protecting it and preventing dust and dirt from contaminating the elastic element 4 and the support 1. The flexible sleeve 5 can be made of elastic flexible materials such as foam or expanded EVA. Foam is a material made of foamed plastic particles, and expanded EVA is a material copolymerized from ethylene and vinyl acetate. The two ends of the flexible sleeve 5 are in contact with the fixed element 2 and the rotating element 3, respectively. The flexible material can avoid affecting the rotation of the rotating element 3 and can play a buffering role and assist in resetting when the rotating element 3 rotates.

[0085] In some embodiments, combined with Figure 8 As shown, the fixing member 2 has a recess 26 formed on the side near the rotating member 3; the flexible sleeve 5 extends into the recess 26 on the side away from the rotating member 3, and there is a gap between the flexible sleeve 5 and the side wall of the recess 26.

[0086] Specifically, one end of the flexible sleeve 5 contacts the rotating component 3, and the other end extends into the recess 26 and contacts the bottom wall of the rotating component 3 to prevent the flexible sleeve 5 from detaching from the ear cup structure; wherein, there is a gap between the peripheral wall of the flexible sleeve 5 and the side wall of the recess 26 to avoid affecting the rotational flexibility of the rotating component 3.

[0087] The assembly process of the ear cup structure is as follows: The second base shaft 12 is passed through the second mounting hole 31, and positioned relative to the rotating member 3 on the side opposite to the fixed member 2. Then, the bracket 1 is rotated by a certain angle, specifically 90°, to align the second base shaft 12 with the second mounting groove 32. The second base shaft 12 is then pressed into the second mounting groove 32, allowing the second pin 15 to pass through the second connecting hole 33 and be inserted into the second base shaft 12. The end of the second pin 15 protrudes relative to the second base shaft 12 and is rotatably connected to the second connecting hole 33. Thus, the second base shaft 12 and the rotating member 3 are rotatably connected. One end of the elastic member 4 is engaged in the annular groove 8 of the rotating member 3, and the elastic member 4 is annularly... The fixed shaft 13 is arranged around the flexible sleeve 5 around the elastic member 4, with one end of the flexible sleeve 5 in contact with the rotating member 3; the first mounting hole 21 of the fixed member 2 is aligned with the first base shaft 11, and the first base shaft 11 is made to pass through the first mounting hole 21. Then the fixed member 2 is rotated at a certain angle to ensure that the first base shaft 11 is aligned with the first mounting groove 22. Then the first base shaft 11 is pressed into the first mounting groove 22, so that the first pin 14 passes through the first connecting hole 23 and is inserted into the first base shaft 11. The end of the first pin 14 protrudes relative to the first base shaft 11 and is rotatably connected to the first connecting hole 23. Thus, the first base shaft 11 is rotatably connected to the fixed member 2, completing the assembly of the earmuff structure.

[0088] According to an embodiment of the present invention, another aspect provides an earphone, including an earcup structure as described in any of the above claims. The earcup structure includes a fixing member 2, a rotating member 3, a support 1, and an elastic member 4. The fixing member 2 can be an earphone arm, and the rotating member 3 can be an earphone back shell. The side of the fixing member 2 facing away from the rotating member 3 is covered with an upper cover 6, and the upper cover 6 covers a first protrusion 25. By providing the support 1 and the elastic member 4, the earphone can fit the user's head appropriately when worn and can automatically reset after wearing, resulting in strong performance.

[0089] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
