Description

Earcup structure and headphones Technical Field

[0001] This application relates to the field of headphone manufacturing technology, and in particular to an earcup structure and a headphone having the earcup structure. Background Technology

[0002] With the development of the national economy and the continuous improvement of living standards, people's entertainment needs in daily life have also increased. Most existing electronic devices are equipped with headphones, which can be divided into wired headphones, Bluetooth headphones, and over-ear headphones. Over-ear headphones have become an essential accessory for people to listen to music and play games because they are less harmful to the ears and more comfortable.

[0003] Over-ear headphones feature a headband with earcups at both ends. When using the headphones, the headband supports the head, and the earcups cover the ears to prevent external noise from entering, improving sound quality and enhancing the user experience. However, due to differences in head size and face shape, the earcups cannot fit perfectly around every user's ear, resulting in poor noise isolation, low comfort, and limited versatility, indicating room for improvement.

[0041] The earcup structure 100 according to an embodiment of this application is described below with reference to Figures 1-10. The structure is simple, which can improve the versatility of use, meet different usage needs, and improve the sound isolation effect of the headphones 101, ensuring the sound effect and comfort of the headphones 101.

[0042] As shown in Figures 1-10, an earmuff structure 100 according to an embodiment of the present application includes: an earmuff housing 2 and an earmuff pivot 1 connected between the earmuff housing 2 and the headband 102.

[0043] The earcup housing 2 includes a floating seat 4 that rotatably engages with it. The axis of rotation of the floating seat 4 is parallel to the width direction of the earcup housing 2. One end of the earcup pivot 1 is inserted into the earcup housing 2 and connected to the floating seat 4, while the other end is connected to the headband 102. The earcup pivot 1 rotatably engages with the earcup housing 2 via the floating seat 4, allowing the earcup housing 2 to swing relative to the earcup pivot 1 within a certain angle range. Additionally, the earcup housing 2 includes an elastic element 5 for pushing the floating seat 4 to rotate. When the user wears the headphones, the elastic element 5 causes the earcup housing 2 to tend to swing towards the user's ear relative to the earcup pivot 1, ensuring the earcup structure 100 remains in close contact with the user's ear.

[0044] In some embodiments, the rotation axis of the floating seat 4 is defined as the first axis. The earcup housing 2 also includes a floating column 21 passing through the floating seat 4. The floating seat 4 has a floating through-hole 421 through which the floating column 21 passes. The length of the floating through-hole 421 is adapted to the length of the floating column 21 along the first axis to prevent the floating seat 4 from shifting along the first axis. The floating column 21 guides the floating seat 4, limiting its swing path and ensuring the stability of the fit between the floating seat 4 and the earcup housing.

[0045] In this embodiment, the axis, width direction, and height direction of the earcup structure 100 are defined. The axis of the earcup structure 100 refers to a straight line passing through the geometric center of the earcup structure 100 along the width direction of the earcup shell 2. When a user wears the headphones 101, the axis of the earcup structure 100 extends in a direction close to or away from the user's ear; the height direction of the earcup structure 100 is vertical; the width direction of the earcup structure 100 is parallel to the front-back direction of the user's head, and the width direction of the earcup structure 100 is perpendicular to the axis and height direction of the earcup structure 100. The axis, width direction, and height direction of the earcup shell 2 are consistent with the axis, width direction, and height direction of the earcup structure 100, respectively.

[0046] Specifically, the headphones 101 are provided with earcup structures 100, and there are two earcup structures 100. The two earcup structures 100 can be connected to the two ends of the headband 102 respectively, and the headband 102 can support the user's head, so that the user can place the two earcup structures 100 on both ears respectively. When the user uses the headphones 101, the headband 102 can support the head, and the two earcup structures 100 can be placed over both ears respectively. At this time, the headband 102 can deform, so that the earcup structures 100 completely cover the ears, thereby isolating external noise, improving the sound effect of the headphones 101, and thus improving the user experience. When the headphones 101 are not in use, the user can hang the headband 102 on the neck or bag strap, etc., for convenient placement, and the headphones 101 can also be used as decoration, increasing the flexibility of setup.

[0047] Furthermore, the earcup structure 100 is provided with an earcup housing 2, which is located on the outermost side of the earcup structure 100. The earcup housing 2 defines an installation space inside, which can accommodate the components required for the operation of the earcup structure 100. The earcup housing 2 can provide mounting points for the components, and it can also protect and support the components inside the earcup structure 100, ensuring the operational reliability of the earcup structure 100. The earcup structure 100 is also provided with an earcup pivot 1, one end of which can be connected to the earcup housing 2, and the other end can be connected to the headband 102, thereby connecting the earcup structure 100 to the headband 102 and ensuring the reliability of the headphones 101.

[0048] Furthermore, the earcup pivot 1 is rotatably engaged with the earcup housing 2 via a floating seat 4. A through mounting hole 43 is formed within the floating seat 4, and the earcup pivot 1 is inserted into the mounting hole 43, thus connecting the earcup pivot to the floating seat 4. Additionally, the earcup pivot 1 can rotate relative to the floating seat 4 around the axis of the mounting hole 43, meaning it can rotate relative to the earcup housing 2. When the headphones 101 are worn on the user's head, the angle of the earcup structure 100 relative to the user is adjustable, thereby improving the fit between the earcup structure 100 and the user's face and enhancing the user experience.

[0049] Simultaneously, the floating seat 4 is also rotatably engaged with the earcup shell 2, with their rotation axes parallel to the width direction of the earcup shell 2. One end of the earcup shaft 1 is inserted into the floating seat 4, allowing the earcup shaft 1 to drive the floating seat 4 to float relative to the earcup shell 2. The earcup shell 2 can rotate relative to the earcup shaft 1 around the axis of the mounting hole 43, i.e., the earcup shell 2 rotates circumferentially around the earcup shaft 1; it can also swing (or float) around the first axis. When the user's face folds differently, the earcup shell 2 can rotate circumferentially along the earcup shaft 1 to adapt to different user face shapes. And when the user's face width is different, the earcup shell 2 can float to adapt to different user face widths, meeting different usage needs. Here, the width direction of the earcup structure 100 refers to the direction between the front and back sides of the user when the user wears the headphones 101 on their head.

[0050] The earcup housing 2 is equipped with an elastic element 5 that cooperates with the floating seat 4. The elastic element 5 can be configured as a spring, elastic sheet, or other structures. The structure is simple and the installation cost is low. When the floating seat 4 floats under the action of an external force, the floating seat 4 will apply a force to the elastic element 5 to compress it. At this time, the elastic element 5 undergoes elastic deformation. When the external force is removed, the elastic element 5 returns to its original deformation and applies an elastic force to the floating seat 4, thereby causing the floating seat 4 to return to its original position. This allows the earcup housing 2 to have a tendency to swing relative to the earcup pivot 1 toward the user's ear. This allows the earcup structure 100 to fit snugly around the ear, preventing the earcup structure 100 from being too loose, which would result in poor noise reduction performance of the headphones 101 and improve the sound effect of the headphones 101. It also prevents the earcup structure 100 from clamping the head too tightly, which could cause pain in the user's ear and other areas. This improves the comfort of using the headphones 101. The simple structure can improve versatility and meet different usage needs.

[0051] According to the embodiment of this application, the earcup structure 100 is provided with a floating seat 4 inside the earcup housing 2, so that the earcup pivot 1 can float together with the floating seat 4 relative to the earcup housing 2, and the earcup housing 2 can rotate around the earcup pivot 1. This allows the earcup structure 100 to adapt to different face shapes and ear shapes, thereby improving versatility and meeting different usage needs. It also allows the earcup structure 100 to completely cover the outside of the ear, thereby improving the sound insulation effect of the headphones 101, ensuring the sound effect and comfort of the headphones 101. The structure is simple, the usage effect is better, and the application range is wider.

[0052] In some embodiments, the earmuff structure 100 includes an earmuff housing 2 and an earmuff pivot 1 connected between the earmuff housing 2 and the headband 102. One end of the earmuff pivot 1 is inserted into the earmuff housing 2 and connected to a floating seat 4. The earmuff pivot 1 is rotatably engaged with the earmuff housing 2 through the floating seat 4. The axis of rotation between the floating seat 4 and the earmuff housing 2 is parallel to the width direction of the earmuff housing 2. The earmuff housing 2 is provided with an elastic element 5 that drives the floating seat 4 to rotate, so that the earmuff housing 2 has a tendency to swing toward the user's ear relative to the earmuff pivot 1.

[0053] The floating seat 4 has a floating through hole 421 through which the floating column 21 passes. The floating column 21 passes through the floating through hole 421, ensuring that the floating seat 4 can only move along the floating column 21 when floating, thus guaranteeing the reliability of the floating trajectory of the floating seat 4. The floating through hole 421 can be constructed as an elongated oval hole, and it should also have sufficient space for relative movement with the floating column 21. Therefore, the opening area of ​​the floating through hole 421 is larger than the cross-sectional area of ​​the floating column 21, facilitating installation and reducing the required assembly precision.

[0054] Furthermore, the length of the floating perforation 421 and the floating column 21 along the first axis is adapted so that the floating perforation 421 can limit the floating column 21 along the first axis, thereby preventing the floating seat 4 from shifting along the first axis and avoiding the earcup housing 2 from moving relative to the earcup pivot 1 along the first axis, which would cause the earcup structure 100 to shift during use and ensure the user experience.

[0055] Furthermore, the floating perforation 421 is configured to extend in a direction intersecting with the first axis, so that when the floating seat 4 floats, the position of the floating column 21 in the floating perforation 421 can be adjusted in a direction intersecting with the first axis, thereby changing the angle between the earcup shell 2 and the end of the earcup pivot 1 that extends into the floating seat 4, so that the earcup structure 100 can adapt to different face shapes, meet different usage needs, and improve wearing comfort.

[0056] In some embodiments, a fixed seat 3 is detachably connected to the inner wall of the earcup housing 2, and a shaft groove is formed between the fixed seat 3 and the inner wall of the earcup housing 2. The floating seat 4 is provided with a rotating shaft 411 that rotatably engages with the shaft groove, and the rotating shaft 411 of the floating seat 4 rotates relative to the earcup housing 2.

[0057] Specifically, the earcup housing 2 may be provided with a fixed seat 3, which is detachably connected to the inner wall of the earcup housing 2. That is, the fixed seat 3 can be connected to the inner wall of the earcup housing 2 through connectors, etc., which facilitates installation and subsequent maintenance. The floating seat 4 can be floatingly installed on the fixed seat 3 and the earcup housing 2. The floating seat 4 can be limited to ensure the reliability of the floating seat 4. A shaft groove is formed between the fixed seat 3 and the inner wall of the earcup housing 2. The earcup housing 2 is provided with a rotating support groove 23. The fixed seat 3 is provided with a mating groove. The rotating support groove 23 and the mating groove together define the shaft groove. The floating seat 4 is provided with a rotating shaft 411, which can rotate and engage with the shaft groove.

[0058] Furthermore, the length direction of the rotating shaft 411 is parallel to the first axis. The rotating shaft 411 can be configured as a cylindrical shaft. The rotating support groove 23 is configured as a groove and is open to the side away from the earcup housing 2. The inner wall of the rotating support groove 23 can be constructed as an arc-shaped support surface 231. When the floating seat 4 is installed on the earcup housing 2, the rotating shaft 411 can be placed in the rotating support groove 23 through the opening, and the rotating shaft 411 can be rotatably supported on the arc-shaped support surface 231. When the floating seat 4 floats, the rotating shaft 411 can rotate relative to the arc-shaped support surface 231. The outer wall of the rotating shaft 411 is also configured as an arc, which can ensure the smoothness of the floating process of the floating seat 4, improve the user experience, and reduce the friction between the rotating shaft 411 and the rotating support groove 23, extend the service life of the rotating shaft 411 and the rotating support groove 23. The shaft groove can limit the rotation shaft 411 and ensure the reliability of the operation of the rotating shaft 411.

[0059] Furthermore, two rotating shafts 411 can be configured, symmetrically distributed on both sides of the floating seat 4, and two shaft grooves are also configured, with the two shaft grooves and the two rotating shafts 411 corresponding one-to-one, so that each rotating shaft 411 can be rotatably supported in the shaft groove. When the floating seat 4 floats, the rotating shafts 411 and the shaft grooves interact. By configuring two rotating shafts 411, the force can be dispersed, thereby extending the service life of the rotating shafts 411. Moreover, by symmetrically arranging the rotating shafts 411 on both sides of the floating seat 4, the force on both sides of the floating seat 4 is even, ensuring the operational reliability of the floating seat 4, and avoiding deformation caused by excessive force on one side of the floating seat 4, thus extending the service life of the floating seat 4.

[0060] In some embodiments, the floating seat 4 includes a rotating part 41 and a floating part 42 connected together. The rotating part 41 is rotatably engaged with the earmuff housing 2 along a first axis. The floating column 21 passes through the floating part 42, and the floating part 42 is swayable about the first axis.

[0061] Specifically, the fixed base 3 is fixedly installed on the earcup housing 2, and the floating base 4 is rotatably installed between the fixed base 3 and the earcup housing 2 along the first axis. As shown in Figures 2 and 4, the floating base 4 can be divided into a rotating part 41 and a floating part 42. The floating part 42 and the rotating part 41 can be connected by welding or integral molding. The end of the earcup shaft 1 can extend into the rotating part 41, so that the earcup shaft 1 can rotate relative to the floating base 4. The rotating part 41 is rotatably engaged with the earcup housing 2 along the first axis, that is, the rotating part 41 is rotatably installed on the earcup housing 2, so that the floating base 4 as a whole can rotate along the first axis.

[0062] Furthermore, one of the floating part 42 and the floating column 21 can be configured as a guide hole, and the other can be configured as a guide column. That is, when the floating part 42 is configured as a guide hole, the floating column 21 can be configured as a guide column, and when the floating part 42 is configured as a guide column, the floating column 21 can be configured as a guide hole. In this embodiment, the floating part 42 is configured as a guide hole, and the floating column 21 is configured as a guide column, so that the floating column 21 can pass through the floating part 42, and the floating part 42 can float along the floating column 21, thereby allowing the entire floating seat 4 to float along the floating column 21, so as to restrict the floating path of the floating seat 4 and ensure the reliability of the floating of the floating seat 4.

[0063] Furthermore, the floating part 42 can swing around the first axis, thereby allowing the entire floating seat 4 to swing around the first axis, thus limiting the swing path of the floating seat 4, ensuring the reliability of the swing of the floating seat 4, adapting to different user face shapes, meeting different usage needs, and improving the flexibility of use.

[0064] In some embodiments, the elastic member 5 is installed between the floating part 42 and the fixed base 3, and elastically presses against the floating part 42 and the fixed base 3 respectively.

[0065] Specifically, the earmuff structure 100 is provided with a fixed base 3 that is fixedly connected to the earmuff shell 2. A floating base 4 is provided between the fixed base 3 and the earmuff shell 2. As shown in Figures 1-3, an elastic member 5 can be installed between the floating part 42 and the fixed base 3, and elastically presses against the floating part 42 and the fixed base 3 respectively. That is, one end of the elastic member 5 can press against the floating part 42, and the other end can press against the fixed base 3.

[0066] Furthermore, the floating seat 4 is installed between the fixed seat 3 and the earcup housing 2. When the floating seat 4 floats relative to the fixed seat 3, the distance between the floating seat 4 and the fixed seat 3 changes accordingly. The elastic element 5 is placed between the floating seat 4 and the fixed seat 3. When the floating seat 4 floats under the action of external force, the distance between the floating seat 4 and the fixed seat 3 changes, which in turn applies a force to the elastic element 5 to compress it. At this time, the elastic element 5 undergoes elastic deformation. When the external force is removed, the elastic element 5 can apply an elastic force to the floating seat 4 and the fixed seat 3 to restore its deformation, thereby causing the floating seat 4 to return to its original position and ensuring reliable use.

[0067] In actual use, the user clamps the earcup structure 100 on both sides of the ears. The user's face will exert force on the earcup structure 100. At this time, the elastic element 5 is compressed. During use, as the user moves, the force applied to the earcup structure 100 also changes, resulting in different degrees of compression of the elastic element 5. However, the force applied to the earcup structure 100 and the elastic force can maintain a balance, so that the earcup structure 100 can still maintain the state of clamping on both sides of the ears. This can ensure the reliability and wearing comfort of the user in sports and other scenarios, meet different usage needs, and improve the flexibility of use.

[0068] In some embodiments, the elastic member 5 is disposed between the floating seat 4 and the fixed seat 3, and the two ends of the elastic member 5 elastically press against the floating part 42 and the fixed seat 3 respectively.

[0069] In some embodiments, the elastic element 5 is configured as a spring, the elastic element 5 is sleeved outside the floating column 21, and the elastic element 5 is extendable and retractable along the floating column 21.

[0070] Specifically, the elastic element 5 is elastically pressed between the fixed seat 3 and the floating seat 4. The elastic element 5 can be constructed as a spring, with one end of the spring pressing against the fixed seat 3 and the other end pressing against the floating seat 4. The floating part 42 of the floating seat 4 can float along the floating column 21 of the ear cup shell 2. The elastic element 5 can be sleeved on the floating column 21, thereby limiting the elastic element 5 and preventing displacement of the elastic element 5, ensuring the reliability of the installation of the elastic element 5. Furthermore, by sleeved on the floating column 21, the elastic force generated by the pressure on the elastic element 5 is also distributed along the floating column 21. Under the action of the elastic force, the floating seat 4 can float relative to the fixed seat 3, thereby making the extension direction of the elastic force the same as the movement direction of the floating seat 4, ensuring the reliability of the floating seat 4.

[0073] Specifically, the floating part 42 is provided with a floating perforation 421, and the floating column 21 can be inserted into the floating perforation 421, so that the floating part 42 can float along the floating column 21. The floating part 42 is provided with at least one floating perforation 421, that is, the floating perforation 421 can be set to one, two or three, etc. The floating column 21 is also set to at least one, that is, the floating column 21 can be set to one, two or three, etc., and at least one floating column 21 is inserted into at least one floating perforation 421 in a one-to-one correspondence. That is, when the floating perforation 421 is set to one, the floating column 21 is also set to one, and one floating column 21 is inserted into one floating perforation 421, so that one part of the floating part 42 can float along the floating column 21. When the floating perforation 421 is set to two or three, etc., the same can be applied.

[0074] Furthermore, in this embodiment, both the floating perforation 421 and the floating column 21 are provided in pairs, with the floating columns 21 spaced apart. When the floating part 42 floats along the floating column 21, the floating column 21 and the floating perforation 421 will generate forces on each other. By providing two floating perforations 421 and two floating columns 21, the forces can be dispersed, thereby reducing the effect of the forces and avoiding deformation or breakage caused by excessive force on a single floating perforation 421 or a single floating column 21. This extends the service life of the floating part 42 and the floating column 21 and ensures the reliability of the floating mechanism.

[0075] In some embodiments, the earcup housing 2 is provided with at least one floating post 21, and the floating seat 4 is provided with at least one floating perforation 421, with at least one floating perforation 421 corresponding to at least one floating post 21.

[0077] Specifically, the earcup housing 2 is provided with a floating column 21, and the floating part 42 forms a floating perforation 421. The floating column 21 can extend into the floating perforation 421. As shown in Figures 1-3, the floating column 21 can be set as a cylindrical column, etc., and one end of the floating column 21 is connected to the earcup housing 2 by welding or integral molding, etc., while the other end is a free end and extends in a direction away from the earcup housing 2.

[0078] Furthermore, the fixed base 3 is provided with a first connecting part, which can be configured as a connecting hole, etc. The free end of the floating column 21 can also be provided with a connecting hole, and the fixed base 3 can be detachably connected and fixed to the free end of the floating column 21 through a first connecting member. That is, the first connecting member can be sequentially inserted into the connecting hole of the fixed base 3 and the connecting hole of the floating column 21 to connect the fixed base 3 and the floating column 21, so that the floating base 4 can float between the ear cup housing 2 and the fixed base 3.

[0079] In addition, the first connecting component can be a bolt or the like, which is simple in structure, easy to install, and has low setup cost. It also allows for the detachable connection of the floating column 21 and the fixed base 3, which is convenient for installation and subsequent maintenance, saving maintenance time and costs and improving the user experience.

[0080] In some embodiments, the earcup housing 2 is further provided with a fixing post 22, the fixing post 22 and the floating post 21 are spaced apart, and the fixing seat 3 and the fixing post 22 are detachably connected by a second connector.

[0081] Specifically, the earcup housing 2 is provided with a fixing post 22, as shown in Figures 1-3. The fixing post 22 can be a cylindrical column, etc. One end of the fixing post 22 is connected to the earcup housing 2 by welding or integral molding, etc., and the other end is a free end, which extends away from the earcup housing 2. The fixing seat 3 is provided with a second connecting part, which can be a connecting hole, etc. The free end of the fixing post 22 can also be provided with a connecting hole. The fixing seat 3 can be detachably connected and fixed to the free end of the fixing post 22 through a second connecting member. That is, the second connecting member can be sequentially inserted into the connecting hole of the fixing seat 3 and the connecting hole of the fixing post 22 to connect the fixing seat 3 and the fixing post 22. The fixing post 22 and the floating post 21 are distributed at intervals, so that the fixing seat 3 can be connected to the earcup housing 2 at multiple points to ensure the reliability of the connection.

[0082] In addition, the second connector can be a bolt or the like, which is simple in structure, easy to install, and has low setup cost. It also detachably connects the fixing column 22 and the fixing seat 3, which is convenient for installation and later maintenance, saving maintenance time and costs and improving the user experience.

[0083] In some embodiments, a mounting hole 43 is formed in the floating seat 4, through which the rotating part 41 and the floating part 42 pass in sequence. The earmuff shaft 1 passes through the mounting hole 43, and a limiting part 431 is provided in the mounting hole 43. When the earmuff shaft 1 rotates to the limit position in the mounting hole 43, it is limited and pressed against the limiting part 431.

[0084] Specifically, the earcup pivot 1 can be inserted into the floating seat 4 and float together with the floating seat 4, as shown in Figures 1-2 and 4-5. The floating seat 4 is also provided with a mounting hole 43, which can pass through the rotating part 41 and the floating part 42 in sequence. One end of the earcup pivot 1 can be inserted into the mounting hole 43, that is, one end of the earcup pivot 1 can be inserted into the rotating part 41 and the floating part 42 in sequence, so that one end of the earcup pivot 1 can float with the floating seat 4 as a whole, increasing the contact area between the earcup pivot 1 and the floating seat 4, thereby ensuring the connection strength between the earcup pivot 1 and the floating seat 4 and ensuring installation reliability.

[0085] Furthermore, one end of the earcup pivot 1 can extend into the mounting hole 43, and the earcup pivot 1 can rotate relative to the mounting hole 43, so that the earcup housing 2 can rotate relative to the earcup pivot 1. As shown in Figures 4-5, a limiting part 431 is provided in the mounting hole 43. The limiting part 431 can be set as a limiting block or a limiting protrusion, etc. The limiting part 431 is provided on the inner wall of the mounting hole 43. When the earcup pivot 1 rotates in the mounting hole 43 and rotates to the limit position, the earcup pivot 1 can be limited and pressed against the limiting part 431, thereby limiting the rotation angle of the earcup pivot 1 in the mounting hole 43. This can ensure that the earcup structure 100 can rotate relative to the earcup pivot 1 while avoiding the earcup structure 100 from completely flipping over, thus ensuring the user experience.

[0086] In some embodiments, the floating seat 4 has a mounting hole 43 for inserting the earmuff shaft 1. The earmuff shaft 1 passes through the mounting hole 43 and rotates around the axis of the mounting hole 43 with the floating seat 4. A limiting part 431 is also provided between the mounting hole 43 and the earmuff shaft 1 to limit the rotation angle range of the earmuff shaft 1, so as to limit the relative rotation angle range between the earmuff shaft 1 and the floating seat 4.

[0087] In some embodiments, the limiting part 431 is configured as a limiting block disposed in the mounting hole 43. The limiting block extends circumferentially along the mounting hole 43 and forms a first limiting surface 432 and a second limiting surface 433 at both ends. The end of the earmuff shaft 1 is provided with a stop block 11. When the earmuff shaft 1 rotates to the maximum position in the circumferential direction, the stop block 11 presses against the first limiting surface 432, and when it rotates to the maximum position in the circumferential direction, it presses against the second limiting surface 433.

[0088] Specifically, a limiting part 431 is provided in the mounting hole 43, and as shown in Figures 4-5, the limiting part 431 can be constructed as a limiting block. The limiting block is installed on the inner wall of the mounting hole 43 and protrudes radially inward. The limiting block can extend along the circumference of the mounting hole 43. The limiting block has a first limiting surface 432 and a second limiting surface 433 formed at both ends along the circumference of the mounting hole 43, respectively. One end of the earmuff shaft 1 extends into the mounting hole 43, and a stop block 11 is provided at this end of the earmuff shaft 1. The stop block 11 is provided at the end of the earmuff shaft 1 and protrudes in a direction away from the earmuff shaft 1.

[0089] Furthermore, as shown in Figures 4 and 5, the stop block 11 can be configured as an arc-shaped plate structure, and the arc of the stop block 11 is the same as the arc of the inner peripheral wall of the mounting hole 43. This ensures the reliability of the rotation of the stop block 11 within the mounting hole 43. When the earcup shaft 1 rotates to its maximum position in the first circumferential direction, the stop block 11 can press against the first limiting surface 432. When it rotates to its maximum position in the second circumferential direction, it can press against the second limiting surface 433. This limits the rotation angle of the earcup shaft 1 within the mounting hole 43, preventing the earcup shell 2 from completely flipping over and improving the user experience.

[0090] The first direction and the second direction can be set to either clockwise or counterclockwise. That is, when the first direction is clockwise, the second direction is counterclockwise, and when the first direction is counterclockwise, the second direction is clockwise. This can be set according to the actual situation to improve the flexibility of the settings.

[0091] In some embodiments, the limiting part 431 includes a limiting block disposed on the inner wall of the mounting hole 43 and a stop block 11 disposed at the end of the earmuff shaft 1. The two sides of the limiting block distributed along the rotation trajectory of the stop block 11 are a first limiting surface 432 and a second limiting surface 433, respectively. Both limiting surfaces are located on the trajectory of the stop block 11 rotating with the earmuff shaft 1. The stop block 11 rotates within the range between the first limiting surface 432 and the second limiting surface 433.

[0092] In some embodiments, there are at least two floating columns 21, which are spaced apart and symmetrically distributed on both sides of the axis of the earcup pivot 1.

[0093] Specifically, at least two floating pillars 21 are provided, that is, the floating pillars 21 can be two, three or four, etc. In this embodiment, as shown in Figures 1-3, two floating pillars 21 are provided, and at least two floating pillars 21 are spaced apart. At least two floating pillars 21 are correspondingly inserted into at least two floating holes 421, that is, at least two floating holes 421 are also spaced apart. At least two floating pillars 21 are symmetrically distributed on both sides of the axis of the earcup rotating shaft 1, so that at least two floating holes 421 are also symmetrically distributed on both sides of the axis of the earcup rotating shaft 1.

[0094] Furthermore, floating perforations 421 and floating posts 21 are symmetrically arranged on both sides of the axis of the earcup rotating shaft 1. When the floating part 42 floats along the floating post 21, the floating post 21 and the floating perforation 421 will generate forces on each other. The symmetrical arrangement of the floating perforation 421 and the floating post 21 on both sides of the axis of the earcup rotating shaft 1 makes the forces on both sides of the floating part 42 equal, and makes the forces on a single floating perforation 421 and the corresponding floating post 21 the same, thus extending the service life of the floating perforation 421 and the floating post 21.

[0095] In some embodiments, the earmuff structure 100 further includes an axial limiting member 6, which is inserted into the floating seat 4. An axial limiting groove 12 is formed on the outer side of the earmuff shaft 1. The axial limiting groove 12 extends circumferentially along the earmuff shaft 1. The axial limiting member 6 is inserted into the axial limiting groove 12 and axially limits the earmuff shaft 1.

[0096] Specifically, the earcup pivot 1 can extend into the floating seat 4 and can rotate relative to the floating seat 4, so that the earcup structure 100 can adjust the rotation angle to meet different usage needs. The earcup pivot 1 has an axial limiting groove 12, which is located at the end of the earcup pivot 1 near the floating seat 4. The axial limiting groove 12 can be arranged around the outer peripheral wall of the earcup pivot 1 and opens radially outward, as shown in Figure 6. The earcup structure 100 also includes an axial limiting member 6, which can be inserted into the floating seat 4. When the earcup pivot 1 extends into the floating seat 4, the axial limiting member 6 can be inserted into the floating seat 4, so that at least part of the axial limiting member 6 can extend into the axial limiting groove 12 through the opening of the axial limiting groove 12 to axially limit the earcup pivot 1, prevent the earcup pivot 1 from coming out of the floating seat 4, ensure the installation reliability of the earcup pivot 1 and the floating seat 4, and ensure the rotation reliability of the earcup pivot 1 to ensure the user experience.

[0097] In some embodiments, an axial limiting groove 12 is provided on the side of the earcup shaft 1, which surrounds the earcup shaft 1. An axial limiting member 6 is detachably connected to the floating seat 4. The axial limiting member 6 is inserted into the axial limiting groove 12 to prevent the earcup shaft 1 from shifting along the floating perforation 421.

[0098] In some embodiments, the axial limiting member 6 includes a middle connecting rod portion 61 and two limiting rod portions 62. The two limiting rod portions 62 are respectively connected to the two ends of the middle connecting rod portion 61. The two limiting rod portions 62 are both limited and inserted into the axial limiting groove 12 and are respectively located on both sides of the earmuff rotating shaft 1.

[0099] Specifically, the floating seat 4 is connected to an axial limiting part 431, which can axially limit the earcup shaft 1 to ensure installation reliability. As shown in Figure 7, the axial limiting part 6 is provided with an intermediate connecting rod part 61 and a limiting rod part 62. There are two limiting rod parts 62, which are arranged in parallel and spaced apart. The intermediate connecting rod part 61 is connected between the two limiting rod parts 62. When the axial limiting part 431 is inserted into the floating seat 4, the two limiting rod parts 62 can be inserted into both sides of the earcup shaft 1 respectively, and can be placed in the axial limiting groove 12 respectively to axially limit the earcup shaft 1. After the insertion is completed, the intermediate connecting rod part 61 can also be placed in the axial limiting groove 12 to ensure the reliability of limiting the earcup shaft 1 at all points. The structure is simple, easy to install, and convenient for later maintenance.

[0100] In some embodiments, the axial limiting member 6 includes a middle connecting rod portion 61 and two limiting rod portions 62. The two limiting rod portions 62 are respectively connected to the two ends of the middle connecting rod portion 61. Both limiting rod portions 62 are limited and inserted into the axial limiting groove 12. The two limiting rod portions 62 are respectively located on both sides of the earmuff rotating shaft 1.

[0101] In some embodiments, the earcup housing 2 is provided with a connecting hole 24, and the earcup pivot 1 is provided with a connecting shaft section 13.

[0102] Specifically, the floating seat 4 is floatingly installed between the fixed seat 3 and the earcup housing 2. One end of the earcup shaft 1 can extend into the earcup housing 2 to rotate with the floating seat 4. As shown in Figure 2, the earcup housing 2 is provided with a connecting hole 24, and the earcup shaft 1 is provided with a connecting shaft section 13. The connecting shaft section 13 can pass through the connecting hole 24 to penetrate the earcup housing 2, so that the end of the earcup shaft 1 can extend into the earcup housing 2 to connect with the floating seat 4. The radial dimension of the connecting shaft section 13 is set to be smaller than the radial dimension of the main body of the earcup shaft 1 to facilitate the installation of the earcup shaft 1.

[0103] Furthermore, the diameter of the connecting hole 24 is set to be larger than the outer diameter of the connecting shaft section 13, so that a floating gap can be formed outside the connecting shaft section 13. One end of the earcup shaft 1 is rotatably installed in the floating seat 4, and when the floating seat 4 floats, one end of the earcup shaft 1 can also float. The floating gap outside the connecting shaft section 13 can ensure the reliability of the earcup shaft 1 and the floating seat 4 floating together, and improve the user experience.

[0104] In some embodiments, the earcup housing 2 is provided with a connecting hole 24 for the earcup shaft 1 to pass through, the earcup shaft 1 is provided with a connecting shaft section 13, the connecting shaft section 13 passes through the connecting hole 24 to penetrate the earcup housing 2, the diameter of the connecting hole 24 is larger than the outer diameter of the connecting shaft section 13 and a floating gap is formed outside the connecting shaft section 13.

The baffle 44 can be set as a circular or rectangular plate structure, as shown in Figures 2 and 4-5. The baffle 44 and the connection hole 24 are distributed opposite each other along the axial direction of the earcup shaft 1. The radial dimension of the baffle 44 is set to be larger than the radial dimension of the connection hole 24, so that the baffle 44 can block the connection hole 24, preventing dust from the outside of the earcup housing 2 from entering the earcup housing 2, ensuring the cleanliness of the inside of the earcup structure 100 and the reliability of use.

[0107] In some embodiments, the floating seat 4 is provided with a baffle 44 on the side near the connection hole 24, and the baffle 44 is located inside the ear cup housing 2.

[0108] This application also proposes an earphone 101.

[0109] The headphone 101 according to the embodiments of this application includes a headband 102 and an earcup structure 100 as described above. There are two earcup structures 100, and the two earcup structures 100 are respectively connected to the two ends of the headband 102.

[0110] Specifically, as shown in Figure 8, the headphones 101 are provided with earcup structures 100 and headband 102. The headband 102 can support the user's head, and the headband 102 can be designed with an arc shape to conform to the shape of the head. The headband 102 is located in the middle of the headphones 101, and the earcup structures 100 can be connected to the ends of the headband 102. There are two earcup structures 100, and the two earcup structures 100 can be connected to the two ends of the headband 102 respectively, so that the user can place the two earcup structures 100 together. The headband 102 is placed on both sides of the ears. When the user uses the headphones 101, the headband 102 can support the head and the earcups 100 can cover the ears. At this time, the headband 102 can deform, so that the earcups 100 completely cover the ears, improving the sound effect of the headphones 101 and thus improving the user experience. When the headphones 101 are not in use, the user can hang the headband 102 on the neck or bag strap, etc., for convenient placement. The headphones 101 can also be used as a decoration, increasing the flexibility of setup.

[0111] According to the embodiments of this application, the earphone 101, by providing a floating seat 4 inside the earcup housing 2, allows the earcup pivot 1 to float together with the floating seat 4 relative to the earcup housing 2, and the earcup pivot 1 to rotate circumferentially relative to the earcup housing 2. This allows the earcup structure 100 to adapt to different face shapes and ear shapes, thereby improving versatility and meeting different usage needs. Furthermore, the earcup structure 100 can completely cover the outside of the ear, thereby improving the sound insulation effect of the earphone 101, ensuring the sound effect and comfort of the earphone 101. The structure is simple, the usage effect is better, and the application range is wider.

[0112] In some embodiments, the end of the earcup pivot 1 located outside the earcup housing 2 is slidably engaged with the headband 102.

[0113] Specifically, the earmuff structure 100 is provided with an earmuff pivot 1. One end of the earmuff pivot 1 is rotatably mounted on the floating seat 4, so that the earmuff structure 100 can adapt to different face shapes and meet different usage needs. The other end of the earmuff pivot 1 is connected to the headband 102. That is, the end of the earmuff pivot 1 located outside the earmuff shell 2 is connected to the headband 102, and the other end of the earmuff pivot 1 is slidably engaged with the headband 102. That is, the distance between the earmuff structure 100 and the headband 102 is adjustable. When the earmuff pivot 1 is extended relative to the headband 102, the distance between the earmuff structure 100 and the headband 102 increases. When the earmuff pivot 1 is shortened relative to the headband 102, the distance between the earmuff structure 100 and the headband 102 decreases.

[0114] Furthermore, both ends of the headband 102 are connected to the earcup structure 100 via the earcup pivot 1. When the user wears the headphones 101, the headband 102 can support the head, and the earcup structure 100 can be placed over the ears. The end of the earcup pivot 1 located outside the earcup shell 2 is telescopically connected to the headband 102, so that the distance between the earcup structure 100 and the headband 102 can be adjusted when the user's head circumference and the relative height of the ears are different, ensuring the fit of the earcup structure 100 to the ears, thereby ensuring the sound effect of the headphones 101 and ensuring the user's experience.

[0115] In some embodiments, the headband 102 is provided with a sliding guide rail 1021, and the earmuff pivot 1 is provided with a sliding engagement part 14. The sliding engagement part 14 is slidably engaged with the sliding guide rail 1021, and the earmuff pivot 1 is retractable relative to the headband 102.

[0116] Specifically, one end of the earcup pivot 1 is rotatably connected to the earcup housing 2, and the other end of the earcup pivot 1 is telescopically connected to the headband 102. As shown in Figures 3-4 and 9-10, a sliding engagement part 14 is provided at the end of the earcup pivot 1 away from the earcup housing 2, and a sliding guide rail 1021 is provided inside the headband 102. The end of the earcup pivot 1 away from the earcup housing 2 can extend into the headband 102, thereby allowing the sliding engagement part 14 to slide with the sliding guide rail 1021. 14 can be configured as a sliding block or similar structure, and the sliding engagement part 14 can be placed inside the sliding guide rail 1021. The movable guide rail extends along the length direction of the headband 102, thereby allowing the sliding engagement part 14 to move within the sliding guide rail 1021 along the length direction of the headband 102. This makes the length of the earcup pivot 1 extending into the headband 102 adjustable, thereby making the earcup pivot 1 retractable relative to the headband 102 to meet different user needs, improve usage flexibility, and ensure user experience.

[0117] The head beam 102 can be configured as an upper part and a lower part, and the upper and lower parts are connected by bolts 1022, which makes installation convenient and the setup cost low. The upper and lower parts can jointly define the sliding guide rail 1021, thereby allowing the sliding mating part 14 to slide with the sliding guide rail 1021, ensuring the operational reliability of the sliding mating part 14.
