[0002] In related technologies, the overall size of over-ear headphones after folding is relatively large, which is not conducive to storage. Utility Model Content

[0003] In view of this, the present application aims to provide a headset to improve the situation where the headset takes up a lot of space when folded.

[0004] To achieve the above objectives, embodiments of this application provide a headset, comprising:

[0005] A headband, the headband including a middle part and two connecting parts, the middle part being connected between the two connecting parts, the middle part having at least one rigidity-reducing groove;

[0006] The two ear shells are rotatably connected to the two connecting parts respectively;

[0007] The headphones have a stowed state and an unfolded state. In the unfolded state, the two connecting parts are coplanar on a first plane, and the two ear shells are spaced apart from each other along a first direction and located outside the clamping space of the headband. In the stowed state, the two ear shells abut against each other along a second direction within the clamping space of the headband, and the middle part undergoes elastic deformation so that at least one of the two connecting parts deviates from the first plane along the second direction. The first direction is parallel to the first plane and intersects with the second direction.

[0008] In some embodiments, the middle portion is arc-shaped, and the ratio of the length of the rigidity-reducing groove to the length of the middle portion ranges from 0.18 to 0.3.

[0009] In some embodiments, the length of the rigidity-reducing groove is between 50 mm and 80 mm.

[0010] In some embodiments, the ratio of the dimension of the rigidity-reducing groove along the second direction to the dimension of the intermediate portion along the second direction is between 0.35 and 0.65.

[0011] In some embodiments, the intermediate portion includes at least two elastic portions disposed along the second direction, and at least one rigidity-reducing groove is defined between two adjacent elastic portions.

[0012] In some embodiments, the elastic portions are integrally formed.

[0013] In some embodiments, at least the elastic part is made of steel.

[0014] In some embodiments, the size of the elastic portion along the second direction ranges from 4 mm to 7 mm.

[0015] In some embodiments, the connecting portion includes:

[0016] Connector, which connects to the middle part;

[0017] The first rotating member is rotatably connected to one end of the connecting member relative to the middle part, and the first rotating member is capable of rotating toward or away from the clamping space of the headband.

[0018] A second rotating component has one end connected to the first rotating component and the other end rotatably connected to the ear shell, the ear shell being able to rotate relative to the second rotating component. The rotation axis of the first rotating component intersects the first plane, and the rotation axis of the second rotating component is parallel to the first plane.

[0019] In some embodiments, the headphones further include earcups, the ear shell includes a rotating portion and an extension portion, the rotating portion is rotatably connected to a second rotating member, the extension portion is connected between the earcup and the rotating portion along the thickness direction of the ear shell, and the dimension of the extension portion along the thickness direction of the ear shell is between 8 mm and 12 mm.

[0020] In some embodiments, the angle between the rotation axis of the second rotating member and the plane containing the ear shell and the wearer's contact surface ranges from 0° to 12°.

[0022] The headphones provided in this application embodiment can achieve a switch from an unfolded state to a retracted state by applying force to the two ear shells, causing at least one of the two connecting parts to deviate from the first plane along a second direction, and driving the middle part between the two connecting parts to undergo elastic deformation. This allows the two ear shells to fold towards the clamping space while also moving backward along the second direction, so that the projections of the two ear shells on the first plane can at least partially overlap, and the sides of the two ear shells away from the connecting parts abut against each other. In the retracted state, the elastic deformation of the middle part provides abutting force between the sides of the two ear shells away from the connecting parts. As a result, the retracted size of the headphones is smaller, and the headband structure is simpler and more reliable, which is beneficial for manufacturing and cost savings.

[0030] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0031] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "connection" 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. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0033] In related technologies, the overall size of over-ear headphones after folding is relatively large, which is not conducive to storage.

[0034] Based on the above, this application provides a headset 10. Please refer to [link / reference]. Figures 1 to 5 The headset 10 includes a headband 11 and two earpieces 12. The headband 11 includes a central portion 111 and two connecting portions 112. The central portion 111 is connected between the two connecting portions 112. The central portion 111 has at least one rigidity-reducing groove 111a. The two earpieces 12 are rotatably connected to the two connecting portions 112 respectively. The headset 10 has a retracted state and an extended state. In the extended state, the two connecting portions 112 are coplanar on a first plane, and the two earpieces 12 are spaced apart from each other along a first direction and located outside the clamping space 11a of the headband 11. In the retracted state, the two earpieces 12 abut against each other along a second direction within the clamping space 11a of the headband 11, and the central portion 111 undergoes elastic deformation, causing at least one of the two connecting portions 112 to deviate from the first plane along the second direction. The first direction is parallel to the first plane, and the first direction intersects the second direction.

[0035] It should be noted that when the headphones 10 are worn, the ear shells 12 are usually in contact with the ears on both sides of the head. The ear shells 12 serve as clamping points to fix the headphones 10 in place.

[0036] The rigidity-reducing groove 111a can reduce the structural strength of the middle part 111, making it easier for it to undergo elastic deformation under the action of external force.

[0037] The connecting part 112 is used to connect the middle part 111 and the ear shell 12.

[0038] The two ear shells 12 are rotatably connected to the two connecting parts 112 respectively, so that the two ear shells 12 can swing and fold into the clamping space 11a of the headband 11 respectively.

[0039] The specific structure of the connecting part 112 is not limited.

[0040] Understandably, in the unfolded state, the headphones 10 are not in a retracted state and are not worn on the head. In the unfolded state, the headband 11 is in a first plane, and the two connecting parts 112 are coplanar with the first plane. The two ear shells 12 are spaced apart from each other along a first direction and are located outside the clamping space 11a of the headband 11, wherein the clamping space 11a is the space defined between the two connecting parts 112 and the middle part 111.

[0041] In the stowed state, the two ear shells 12 abut against each other in the second direction within the clamping space 11a of the headband 11, and the middle part 111 undergoes elastic deformation, so that at least one of the two connecting parts 112 deviates from the first plane in the second direction. That is, the user can apply force to the two ear shells 12, and at the same time, the two ear shells 12 will drive at least one of the two connecting parts 112 to deviate from the first plane in the second direction, and drive the middle part 111 between the two connecting parts 112 to undergo elastic deformation, so that the two ear shells 12 fold towards the clamping space 11a and move backward in the second direction, so that the projections of the two ear shells 12 on the first plane can at least partially overlap, and the side of the two ear shells 12 away from the connecting part 112 abuts against each other, thereby realizing the switching of the headphone 10 from the unfolded state to the stowed state. In the stowed state, the elastic deformation of the middle part 111 causes the two ear shells 12 to abut against each other on the side opposite to the connecting part 112, thus providing abutment force. In this way, the size of the headphones 10 after being stowed is smaller, and the structure of the headband 11 is simpler and more reliable, which is beneficial to manufacturing and cost saving.

[0042] For example, the second direction is perpendicular to the first direction, that is, the second direction is perpendicular to the first plane.

[0043] The headset 10 provided in this embodiment can achieve a switch from an unfolded state to a retracted state by applying force to the two ear shells 12, while the two ear shells 12 respectively drive at least one of the two connecting parts 112 to deviate from the first plane in a second direction, and drive the middle part 111 between the two connecting parts 112 to undergo elastic deformation. This allows the two ear shells 12 to fold towards the clamping space 11a and move backward in the second direction, so that the projections of the two ear shells 12 on the first plane can at least partially overlap, and the sides of the two ear shells 12 away from the connecting parts 112 abut against each other. In the retracted state, the elastic deformation of the middle part 111 provides abutting force for the sides of the two ear shells 12 away from the connecting parts 112. Thus, the retracted size of the headset 10 is smaller, and the structure of the headband 11 is simpler and more reliable, which is beneficial for manufacturing and cost savings.

[0044] In some embodiments, please refer to Figures 1 to 5The middle part 111 is arc-shaped. The ratio of the length of the rigidity-reducing groove 111a to the length of the middle part 111 is in the range of 0.18-0.3.

[0045] For example, the ratio of the length of the rigidity-reducing groove 111a to the length of the middle part 111 is 0.18, 0.2, 0.22, 0.25, 0.28 or 0.3, etc., and is not limited here.

[0046] The middle part 111 is arc-shaped, so that the headband 11 fits the wearer's head and the ear shell 12 fits the wearer's ears, so as to realize the wearing of the headphones 10.

[0047] Here, the ratio of the dimensions between the rigidity-reducing groove 111a and the intermediate part 111 can be the ratio of the arc length to the arc length, or it can be the ratio of the dimensions along the first direction, and there is no limitation here.

[0048] In this embodiment, by setting the ratio of the length of the rigidity-reducing groove 111a to the length of the middle portion 111 between 0.18 and 0.3, the rigidity-reducing groove 111a can appropriately reduce the structural strength of the middle portion 111, making the middle portion 111 more prone to elastic deformation while increasing the clamping force of the headband 11 in the unfolded state.

[0049] In some embodiments, the length of the rigidity-reducing groove 111a is between 50 mm and 80 mm.

[0050] For example, the length of the rigidity reduction groove 111a is 50mm, 55mm, 60mm, 65mm, 68mm, 70mm, 75mm, 78mm or 80mm, etc., and there is no limitation here.

[0051] The length of the rigidity-reducing groove 111a can be the arc length of the rigidity-reducing groove 111a, or the dimension along the first direction.

[0052] By setting the length of the rigidity-reducing groove 111a between 50mm and 80mm, the headband 11 can more easily undergo elastic deformation, while ensuring that the portion of the middle part 111 other than the rigidity-reducing groove 111a has sufficient size, thereby improving the overall integrity and structural strength of the headband 11.

[0053] In some embodiments, please refer to Figures 1 to 5 The ratio of the dimension of the rigidity-reducing groove 111a along the second direction to the dimension of the middle portion 111 along the second direction is between 0.35 and 0.65.

[0054] For example, the ratio of the dimension of the rigidity reducing groove 111a along the second direction to the dimension of the intermediate portion 111 along the second direction is 0.35, 0.4, 0.45, 0.5, 0.6 or 0.65, etc., and is not limited here.

[0055] The dimension of the rigidity-reducing groove 111a along the second direction refers to the width of the rigidity-reducing groove 111a; the dimension of the middle part 111 along the second direction refers to the overall width of the middle part 111.

[0056] By setting the ratio of the dimension of the rigidity-reducing groove 111a along the second direction to the dimension of the middle part 111 along the second direction between 0.35 and 0.65, the middle part 111 can take into account both easy deformation and a certain connection strength.

[0057] In some embodiments, please refer to Figures 1 to 5 The middle portion 111 includes at least two elastic portions 1111 disposed along the second direction. At least one rigidity-reducing groove 111a is defined between two adjacent elastic portions 1111.

[0058] It should be noted that the elastic part 1111 can be a steel strip. At least two steel strips are spaced apart in the second direction to define at least one rigidity reduction groove 111a. The structure of the middle part 111 is simpler and more reliable, and it is also beneficial to manufacturing.

[0059] In some embodiments, the elastic portions 1111 are integrally formed.

[0060] For example, the entire middle section 111 is integrally molded.

[0061] The elastic parts 1111 are integrally molded, which on the one hand makes the structure simpler and facilitates production, and on the other hand can improve the integrity and compactness of the elastic parts 1111. At the same time, it can also improve the overall structural strength of the headband 11.

[0062] In some embodiments, at least the elastic part 1111 is made of steel.

[0063] For example, the entire middle section 111 is a one-piece steel part, which simplifies the structure and reduces the difficulty of manufacturing.

[0064] In this embodiment, at least the elastic part 1111 is made of steel, so that the elastic part 1111 can provide better rotational torque to switch between the stored state and the unfolded state, and at the same time provide a certain clamping force in the unfolded state.

[0065] In some embodiments, please refer to Figures 1 to 5 Along the second direction, the size of the elastic part 1111 ranges from 4mm to 7mm.

[0066] For example, the size of the elastic part 1111 is 4mm, 4.5mm, 5mm, 5.5mm, 5.8mm, 6mm, 6.2mm, 6.5mm or 7mm, etc., and is not limited here.

[0067] In this way, the elastic part 1111 can have a certain width, so that the elastic part 1111 can take into account both easy elastic deformation and a certain structural strength.

[0068] In some embodiments, please refer to Figures 1 to 5 The connecting portion 112 includes a connector 1121, a first rotating member 1122, and a second rotating member 1123. The connector 1121 is connected to the intermediate portion 111. The first rotating member 1122 is rotatably connected to one end of the connector 1121 relative to the intermediate portion 111. The first rotating member 1122 can rotate toward or away from the clamping space 11a of the headband 11. One end of the second rotating member 1123 is connected to the first rotating member 1122, and the other end of the second rotating member 1123 is rotatably connected to the ear shell 12. The ear shell 12 can rotate relative to the second rotating member 1123. The rotation axis of the first rotating member 1122 intersects the first plane, and the rotation axis of the second rotating member 1123 is parallel to the first plane.

[0069] like Figure 3 As shown, the rotation axis of the first rotating member 1122 is represented by Y1, the rotation axis of the second rotating member 1123 is represented by Y2, and the first plane is represented by F1.

[0070] The first rotating member 1122 and the connecting member 1121 are rotatably connected to one end of the middle part 111, that is, one end of the connecting member 1121 is connected to the middle part 111, and the other end is rotatably connected to the first rotating member 1122.

[0071] The rotation axis of the first rotating member 1122 refers to the central axis of rotation of the first rotating member 1122 relative to the connecting member 1121; the rotation axis of the second rotating member 1123 refers to the central axis of rotation of the second rotating member 1123 relative to the ear shell 12.

[0072] One end of the second rotating member 1123 is connected to the first rotating member 1122, and the connection can be fixed.

[0073] For example, the second rotating member 1123 is integrally formed with the first rotating member 1122.

[0074] In this embodiment, the first rotating member 1122 is rotatably connected to the connecting member 1121, so that the first rotating member 1122 can rotate relative to the connecting member 1121 toward or away from the clamping space 11a of the headband 11. One end of the second rotating member 1123 is connected to the first rotating member 1122, and the other end is rotatably connected to the ear shell 12, so that the ear shell 12 can rotate around the rotation axis of the second rotating member 1123, so that the two ear shells 12 can be opposite each other.

[0075] For example, the connector 1121 includes a first sliding part 11211 and a second sliding part 11212 that can slide relative to each other. The first sliding part 11211 is fixedly connected to the middle part 111, and the second sliding part 11212 is rotatably connected to the first rotating member 1122. The second sliding part 11212 and the first sliding part 11211 slide together to adjust the distance between the ear shell 12 and the middle part 111, which is beneficial for the headphone 10 to adapt to different head sizes and improve the adaptability of the headphone 10.

[0076] In some embodiments, please refer to Figures 1 to 5 The headphones 10 also include earcups 13. The ear shell 12 includes a rotating portion 121 and an extension 122. The rotating portion 121 is rotatably connected to a second rotating member 1123. The extension 122 is connected between the earcup 13 and the rotating portion 121 along the thickness direction of the ear shell 12. The dimension of the extension 122 along the thickness direction of the ear shell 12 is between 8 mm and 12 mm.

[0077] It should be noted that there are two earcups 13, one earcup 13 is mounted on one ear shell 12. When the headphones 10 are worn on the head, the earcups 13 are used to cover the ears, thereby fixing the ear shell 12 to the ears.

[0078] The ear shell 12 includes a rotating portion 121 and an extension portion 122, wherein the rotating portion 121 extends along the thickness direction of the ear shell 12 to form the extension portion 122, and the rotating portion 121 forms a rotating cavity that cooperates with the second rotating member 1123.

[0079] The extension 122 is connected between the ear cup 13 and the rotating part 121 along the thickness direction of the ear shell 12. That is, the rotating part 121, the extension 122, and the ear cup 13 are connected in sequence along the thickness direction of the ear shell 12.

[0080] For example, the dimension of the extension 122 along the thickness direction of the ear shell 12 is 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm or 12mm, etc., and there is no limitation here.

[0081] like Figure 3 As shown, the dimension of the extension 122 along the thickness direction of the ear shell 12 is represented by D.

[0082] In this embodiment, by setting the dimension of the extension 122 along the thickness direction of the ear shell 12 to between 8mm and 12mm, in the stored state, the two earmuffs 13 are abutted against each other by the abutting force of the two ear shells 12, and the earmuffs 13 can be elastically compressed along the thickness direction of the ear shell 12. The dimension control of the extension 122 in the thickness direction of the ear shell 12 can be used to control the distance between the two second rotating members 1123, thereby making the distance between the two connecting parts 112 of the headband 11 in the direction perpendicular to the first plane within a suitable range. This improves the situation where the distance between the two connecting parts 112 in the direction perpendicular to the first plane is too large, resulting in excessive external force applied by the connecting parts 112 to the middle part 111, and excessive reaction force applied by the middle part 111 to the two ear shells 12, causing the two ear shells 12 to fail to maintain abutment.

[0083] In some embodiments, the rotating part 121 includes a first part 1211 and a second part 1212. One end of the first part 1211 is formed with a rotating cavity that cooperates with the second rotating member 1123, and the other end is formed with a rotating shaft that rotatably cooperates with the second part 1212. The second part 1212 is formed with a rotating hole that cooperates with the rotating shaft.

[0084] For example, the second part 1212 and the extension part 122 are integrally formed.

[0085] Here, the dimension of the extension 122 along the thickness direction of the ear shell 12 is the distance between the rotating engagement point of the first part 1211 and the second part 1212 and the ear cup 13 in the thickness direction of the ear shell 12. By controlling the distance between the rotating engagement point of the first part 1211 and the second part 1212 and the ear cup 13 in the thickness direction of the ear shell 12, the distance between the two connecting parts 112 of the headband 11 in the direction perpendicular to the first plane is within a suitable range.

[0086] In some embodiments, please refer to Figures 1 to 5 The angle between the rotation axis of the second rotating component 1123 and the plane containing the ear shell 12 and the contact surface with the wearer is in the range of 0° to 12°.

[0087] like Figure 3 and Figure 5 As shown, the rotation axis of the second rotating member 1123 is represented by Y2, the plane where the ear shell 12 contacts the wearer is represented by F2, and the angle between the rotation axis of the second rotating member 1123 and the plane where the ear shell 12 contacts the wearer is represented by α.

[0088] For example, the angle between the rotation axis of the second rotating member 1123 and the plane where the ear shell 12 is located and the contact surface with the wearer is 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11° or 12°, etc., and is not limited here.

[0089] Here, by limiting the rotation axis of the second rotating member 1123 and the angle range between the ear shell 12 and the plane where the wearer's contact surface is located, the distance between the two second rotating members 1123 can also be controlled, so that the distance between the two connecting parts 112 of the headband 11 in the direction perpendicular to the first plane is within a suitable range, and the two ear shells 12 can abut against each other, so that the headphones 10 can be kept in the storage state.

[0090] In some embodiments, please refer to Figures 1 to 5 The initial position is defined as the position where the plane containing the contact surface between the ear shell 12 and the wearer is perpendicular to the first direction. The ear shell 12 can rotate 95° clockwise and 60° counterclockwise relative to the initial position around the rotation axis of the second rotating member 1123.

[0091] like Figure 1 The image shows the headphone 10 with the earcups 12 in their initial position.

[0092] The ear shell 12 can rotate about the rotation axis of the second rotating member 1123 relative to the initial position by an angle of 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90° or 95°, etc., without any restrictions.

[0093] The ear shell 12 can be reversed about the rotation axis of the second rotating member 1123 at an angle relative to the initial position of 0°, 10°, 20°, 30°, 40°, 50° or 60°, etc., without any limitation.

[0094] In this embodiment, the rotation angle of the ear shell 12 about the rotation axis of the second rotating member 1123 relative to the initial position is increased, which facilitates the relative closing of the ear shell 12, the elastic deformation of the headband 11, and the switching to Figure 3 and Figure 5 The storage status is shown.

[0095] In the description of this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Furthermore, without contradiction, those skilled in the art can combine different embodiments or examples described in this application, as well as features of different embodiments or examples.
