Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this application, it should be noted that, unless otherwise expressly 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] The following description, with reference to Figures 1-7, describes an earmuff accessory 2 (e.g., a remote control) according to an embodiment of this application. By setting at least one of the plurality of first magnetic elements 22 to have a different polarity from the others, when the earmuff accessory 2 is connected to other structures, the principle of like poles repelling and unlike poles attracting between magnetic poles makes the adsorption direction of the earmuff accessory 2 and other structures unique. This allows for accurate installation of the relative positions of the earmuff accessory 2 and other structures, avoiding misalignment and thus improving assembly accuracy and efficiency. Furthermore, the magnetic attraction of multiple sets of magnetic poles results in high connection strength and stability between the earmuff accessory 2 and other structures. The structure is simple, easy to assemble, and has good performance.

[0047] Before continuing with the description of the earcup structure 100 of this embodiment, the axial and radial directions of the earcup structure 100 are defined for the purpose of subsequent description. The axial direction of the earcup structure 100, as referred to in this application, is the thickness direction of the earcup structure 100. When a user wears headphones and the earcup structure 100 covers the user's ear, the axial direction of the earcup structure 100 refers to the direction in which the earcup structure 100 approaches and moves away from the ear, and the axis of the earcup structure 100 is a straight line passing through the geometric center of the earcup structure 100 along its axial direction. The radial direction of the earcup structure 100 is the direction perpendicular to the axial direction of the earcup structure 100, that is, the direction perpendicular to the thickness direction of the earcup structure 100. The earmuff structure 100 includes an earmuff body 1 and an earmuff accessory 2. The earmuff body 1 and the earmuff accessory 2 also have an axial direction, a radial direction and an axis, respectively. When the earmuff body 1 and the earmuff accessory 2 are assembled into the earmuff structure 100, the axial direction, radial direction and axis of the earmuff body 1 and the earmuff accessory 2 are consistent with the axial direction, radial direction and axis of the earmuff structure 100.

[0048] As shown in Figures 1-7, an earmuff accessory 2 according to one embodiment of this application includes: an earmuff accessory body 21, wherein the earmuff accessory 2 can be a remote control.

[0049] It should be noted that earcup accessory 2 can be used with other structures, such as earcups, speakers, monitors, fans, and remote-controlled toys. Earcup accessory 2 can send commands to control the power on / off of these structures or other functions during use. Earcup accessory 2 has a wide range of applications and is convenient and quick to use. The outer shell of earcup accessory 2 is usually made of plastic or metal to protect the internal circuitry and components while providing a comfortable grip. The circuit board is the core of earcup accessory 2, consisting of a set of electronic components. These components work together to encode button commands into infrared signals and transmit them. The battery is the power source for earcup accessory 2, usually a dry cell battery or a rechargeable battery. It provides the necessary power to ensure the normal operation of the internal circuitry and components.

[0050] The earmuff accessory body 21 is provided with a plurality of first magnetic elements 22, which are spaced apart and distributed on the earmuff accessory body 21. The first magnetic elements 22 are magnetic. By providing a plurality of first magnetic elements 22 on the earmuff accessory body 21, magnetic attraction connection between the earmuff accessory body 21 and other structures can be realized. The plurality of first magnetic elements 22 are spaced apart and evenly distributed, which can make multiple positions of the earmuff accessory body 21 magnetically attracted to other structures. This can effectively improve the connection strength of the earmuff accessory body 21. The magnetic attraction connection method is simple and convenient to operate, and facilitates the disassembly, assembly and maintenance of the earmuff accessory 2.

[0051] In order to accurately show the position of the first magnetic component 22, the internal circuitry and components of the earmuff accessory body 21 are hidden in Figures 1 and 2 of this embodiment, so as not to obscure the first magnetic component 22.

[0052] Furthermore, the first magnetic component 22 can be constructed as a magnet, and multiple first magnetic components 22 can be detachably connected to the earmuff accessory body 21. The multiple first magnetic components 22 can be connected to the earmuff accessory body 21 through an adhesive, or they can be connected by mechanical means, such as by using a heat-embedding method to integrally mold the first magnetic component 22 and the earmuff accessory body 21. The setting method is firm and reliable.

[0053] The earcup accessory body 21 has a connecting side, and the polarity of a portion of the first magnetic elements 22 facing the connecting side is different from that of another portion of the first magnetic elements 22 facing the connecting side.

[0054] Specifically, one side of the earmuff accessory body 21 can be provided with a connecting side for connection with other structures. The magnetic attraction portions of multiple first magnetic elements 22 extend toward the connecting side. Correspondingly, other structures are also provided with multiple magnetic attraction portions for magnetic attraction with the first magnetic elements 22. The two poles of the first magnetic elements 22 are N pole and S pole, respectively. The magnetic poles of some first magnetic elements 22 facing the connecting side are different from those of other first magnetic elements 22 facing the connecting side. That is to say, not all the magnetic poles of all first magnetic elements 22 facing the connecting side are N pole or S pole. The multiple magnetic attraction portions of other structures correspond one-to-one with the magnetic poles of multiple first magnetic elements 22. When two magnets are close, they are affected by the magnetic field repulsion of like poles and attraction of unlike poles. Therefore, when the magnetic properties of multiple first magnetic elements 22 and multiple magnetic attraction portions are different, the earmuff accessory 2 can attract and adhere to each other with other structures. When the earmuff accessory body 21 is correctly mounted on the other structures, each first magnetic element 22 is magnetically attracted with a magnetic attraction portion.

[0055] In practical design, the number of first magnetic components 22 and magnetic suction parts can be the same to ensure reliable magnetic adsorption and avoid wasting magnets. The number of first magnetic components 22 and magnetic suction parts can be three, four, five, six, etc., and multiple first magnetic components 22 can be arranged with their magnetic poles opposite to those of the remaining first magnetic components 22. The division is based on the polarity of the magnetic poles of the first magnetic components 22 facing the connection side. One of the multiple first magnetic components 22 can be a different magnetic pole, or two, three, etc. can be set, and multiple magnetic suction parts can also have at least one different magnetic pole. The number of different magnetic poles in the earcup accessory body 21 and other structures is the same to ensure reliable connection. The arrangement methods are diverse and can be flexibly selected.

[0056] Therefore, by setting multiple first magnetic elements 22 on the earcup accessory body 21, the earcup accessory 2 can be connected to other structures by multiple sets of magnetic poles. The connection strength between the two is high and the stability is good. Moreover, some of the multiple first magnetic elements 22 have different polarities facing the connection side, and the magnetic poles of other structures correspond to the magnetic poles of the earcup accessory body 21. Through the principle of like poles repelling and unlike poles attracting, the adsorption direction of the earcup accessory body 21 and other structures is unique. In this way, magnetic connection can be achieved, and positioning installation can be achieved. This can avoid misalignment of the earcup accessory body 21 and other structures in the vertical and horizontal directions, thereby improving assembly accuracy and assembly efficiency. The structure is simple, easy to assemble, and has good performance.

[0057] In some embodiments, an accessory cavity 23 (also referred to as a mounting cavity) is formed within the earmuff accessory body 21. A first magnetic element 22 is located within the accessory cavity 23, as shown in FIG2. The accessory cavity 23 of the earmuff accessory body 21 has an open side along the attraction direction and can be opened to other structures for mounting the first magnetic element 22. The first magnetic element 22 is provided to extend along the attraction direction, with one end of the first magnetic element 22 connected to the accessory cavity 23, thereby realizing the connection and fixation between the first magnetic element 22 and the earmuff accessory body 21. The other end of the first magnetic element 22 is used for magnetic attraction with other structures, and at least a portion of the structure of the first magnetic element 22 is located within the accessory cavity 23. A plurality of first magnetic elements 22 are spaced apart and distributed within the accessory cavity 23, and the plurality of first magnetic elements 22 are distributed one-to-one with the plurality of magnetic attraction parts of other structures, which makes the attraction between the earmuff accessory body 21 and other structures more reliable, thereby improving the stability of the connection between the two.

[0058] The spacing between the multiple first magnetic components 22 is relatively large, and correspondingly, the spacing between the multiple other magnetic attraction parts is also relatively large. This avoids the repulsive force between the multiple first magnetic components 22 and between the multiple magnetic attraction parts, making the attraction force between the multiple sets of magnetic poles more uniform, the magnetic attraction effect better, and the installation operation simple and convenient.

[0059] In some embodiments, the earmuff accessory body 21 includes a main body shell 24 and an accessory cover plate 25 (also referred to as a mounting cover plate). The connecting side is the side of the main body shell 24 facing away from the accessory cover plate 25. The side of the main body shell 24 away from the connecting side defines an accessory groove 241 (also referred to as a mounting groove). The accessory cover plate 25 is connected to the opening of the accessory groove 241 to close the accessory groove 241 and together with the main body shell 24 defines an accessory cavity 23.

[0060] Specifically, as shown in Figure 3, the outer structure of the earmuff accessory body 21 can be constructed as a circular structure. Both the main shell 24 and the accessory cover plate 25 are circular structures. As shown in Figures 1 and 2, an accessory groove 241 is formed inside the main shell 24. The accessory groove 241 can be constructed as a circular groove, and the accessory groove 241 is open in the direction away from the connecting side. The accessory cover plate 25 is set to connect to the opening of the accessory groove 241, which can keep the accessory groove 241 in a closed state. The accessory groove 241 is closed by the accessory cover plate 25 to form an accessory cavity 23. In this way, the structure inside the accessory cavity 23 is hidden inside the earmuff accessory body 21, which can play a protective and sealing role, and can keep the non-connecting side structure of the earmuff accessory body 21 intact, and play a good decorative role.

[0061] By setting the accessory slot 241 and the connecting side in opposite directions, the main body shell 24 can be used on the accessory slot 241 side for the installation of some other structures of the earmuff accessory body 21, and on the connecting side, the main body shell 24 can be used to connect the earmuff accessory body 21 to other structures. The installation and disassembly of the two will not interfere with each other, which facilitates the maintenance of the overall structure.

[0062] It should be noted that the accessory cover 25 can be connected to the main shell 24 by means of adhesive bonding, snap-fit, etc., which is simple and convenient for assembly. Furthermore, the accessory cover 25 and the main shell 24 can be an integral structure, which reduces the connection steps and maintains their airtightness.

[0063] In some embodiments, the inner wall of the main body shell 24 is provided with a plurality of mounting posts 242, and the mounting posts 242 are provided with grooves 2421 for mounting the first magnetic element 22.

[0064] In this way, by setting multiple first magnetic components 22 to be installed in the grooves 2421 of multiple mounting posts 242 respectively, multiple first magnetic components 22 can be installed in the predetermined position, ensuring the accurate installation of the first magnetic components 22 in the main body shell 24, and facilitating the alignment of multiple first magnetic components 22 with multiple magnetic suction parts of other structures. The installation is convenient, the installation accuracy is high, and the maintenance and replacement of the first magnetic components 22 are convenient. Furthermore, the installation of the first magnetic components 22 in the mounting posts 242 can limit the outer periphery of the first magnetic components 22, avoiding accidental collisions and tilting. Its structure has good strength and long service life.

[0065] Specifically, as shown in Figure 2, multiple mounting posts 242 extend along the attraction direction within the main body shell 24. Each mounting post 242 has a groove 2421 for mounting the first magnetic component 22, and the groove 2421 is open towards the side closest to the connection. This allows one end of the first magnetic component 22 to be mounted within the groove 2421, while the other end protrudes from the end of the mounting post 242. This enables the multiple first magnetic components 22 to magnetically attract and engage well with other structures. The mounting posts 242 can be integrated with the main body shell 24, resulting in a simple structure and low processing cost.

[0066] In some embodiments, the main body shell 24 is provided with a plurality of reinforcing ribs 243, which intersect at the middle of the main body shell 24. The reinforcing ribs 243 divide the accessory cavity 23 into a plurality of sub-cavities 231, and each mounting post 242 is located in a different sub-cavity 231.

[0067] Specifically, the reinforcing ribs 243 can strengthen the structural strength of the main shell 24. As shown in Figure 2, multiple reinforcing ribs 243 and multiple mounting posts 242 are distributed on the same side of the main shell 24, and all protrude towards the connecting side of the ear cup accessory body 21. The multiple reinforcing ribs 243 extend towards the middle of the main shell 24 and cross and connect at the middle of the main shell 24. The multiple reinforcing ribs 243 are evenly distributed, making the overall structure more regular and orderly. The ends of the multiple reinforcing ribs 243 are connected to the inner sidewall of the main shell 24. In this way, the multiple reinforcing ribs 243 can support the inner bottom wall and inner sidewall of the main shell 24 to improve the structural strength of the main shell 24. The multiple reinforcing ribs 243 can divide the accessory cavity 23 into multiple sub-cavities 231 to accommodate multiple mounting posts 242.

[0068] The first magnetic component 22 can be four, that is, there are four mounting posts 242. The four mounting posts 242 are located in different sub-cavities 231, which can increase the spacing between the four mounting posts 242. The reinforcing ribs 243 can be eight, and the eight reinforcing ribs 243 are evenly spaced apart along the circumference of the main shell 24. In this way, the overall structure is more uniform. The number of reinforcing ribs 243 and the arrangement of mounting posts 242 are not limited to those described in this embodiment, and can be set according to actual needs.

[0069] In some embodiments, the earmuff accessory 2 further includes an electronic control board 26 and an operation button 27. The electronic control board 26 is located inside the earmuff accessory body 21, and the operation button 27 is movably mounted on the earmuff accessory body 21. The operation button 27 is adapted to press against the electronic control board 26 after being pressed.

[0070] Specifically, the control board 26 and operation button 27 in the earcup accessory 2 are its core components. They jointly realize the control function of the earcup accessory 2. The control board 26 is connected inside the earcup accessory body 21, and the operation button 27 is movably connected to the earcup accessory body 21. Its movement can be a pressing operation. When the operation button 27 is pressed, it moves relative to the earcup accessory body 21. When the operation button 27 moves towards the control board 26 and presses against the control board 26, the corresponding circuit is triggered. The control board 26 receives the input signal from the operation button 27 and outputs the command. When the operation button 27 is pressed once and makes contact with the control board 26, the control board 26 can control the earcup accessory 2 to open. When the operation button 27 is pressed again, the control board 26 can control the earcup accessory 2 to close. The control board 26 can also control the earcup accessory 2 to perform functions such as volume adjustment, song switching, and channel switching. The operation button 27 can be set to one, two, etc., to correspond to different functions of the earcup accessory 2. As shown in Figure 5, the control board 26 is also equipped with a vibration motor 261, which provides vibration feedback when the earcup accessory 2 is opened and closed. Furthermore, the earcup accessory 2 has a sealing plate 211 on the connecting side, which can hide and protect the internal structure of the earcup accessory.

[0071] Therefore, by setting the operation button 27 and the electronic control board 26 together, the control function of the earmuff accessory 2 can be realized, and the operation of the earmuff accessory 2 is simple and convenient.

[0072] Furthermore, the electronic control board 26 can be detachably connected to the earmuff accessory body 21 via bolts or other connectors, making the connection simple and easy to install and disassemble.

[0073] In some embodiments, the earmuff accessory 2 further includes an elastic element 28 for pushing the operation button 27 away from the electronic control board 26, the elastic element 28 being disposed between the operation button 27 and the earmuff accessory body 21.

[0074] In this way, the elastic element 28 applies an elastic force toward the operation button 27, which can cause the operation button 27 to move away from the electronic control board 26, thereby disengaging the operation button 27 from the electronic control board 26, thus releasing the triggering function of the operation button 27 from the electronic control board 26, and allowing the operation button 27 to return to its initial position, making it convenient to press the operation button 27 again in the future.

[0075] Specifically, the elastic element 28 has the ability to elastically expand and contract, and can be a spring or an elastic sheet. In this embodiment, the elastic element 28 is a spring. As shown in Figures 5 and 6, the elastic element 28 can be sleeved on the outer periphery of the operation button 27. One end of the elastic element 28 presses against the operation button 27 and the other end presses against the earmuff accessory body 21. In this way, when the operation button 27 and the earmuff accessory body 21 are not moving, the elastic element 28 is in a natural state. When the operation button 27 is pressed and moves towards the electronic control board 26, the elastic element 28 is in a compressed state, and the elastic element 28 applies an elastic force to the operation button 27 away from the electronic control board 26, which can make the operation button 27 move away from the electronic control board 26, thereby realizing the reset of the operation button 27 and the return of the elastic element 28 to its natural state. Its movement is simple, assembly is convenient, and manufacturing cost is low.

[0076] In some embodiments, the earmuff accessory body 21 has a fixing hole 244, and the operation button 27 includes a pressing part 271, a limiting part 2721, and a through part 272 that passes through the fixing hole 244. One end of the through part 272 extending out of the earmuff accessory body 21 is connected to the pressing part 271, and the other end of the through part 272 extending into the earmuff accessory body 21 is connected to the limiting part 2721. The cross-sectional diameters of the pressing part 271 and the limiting part 2721 perpendicular to the axis of the fixing hole 244 are both larger than the diameter of the fixing hole 244. An elastic member 28 is disposed between the pressing part 271 and the earmuff accessory body 21.

[0077] Specifically, as shown in Figures 5 and 6, the earmuff accessory body 21 has a fixing hole 244. The fixing hole 244 extends along the pressing direction and passes through the inner and outer sides of the earmuff accessory body 21. The through part 272 of the operation button 27 passes through the fixing hole 244, which can realize the installation of the operation button 27. The through part 272 can make a pressing contact with the electronic control board 26.

[0078] As shown in Figure 6, the pressing part 271, the through part 272, and the limiting part 2721 are connected in sequence. The through part 272 is perpendicularly connected to the pressing part 271, and the limiting part 2721 is connected to the side of the through part 272 away from the pressing part 271. That is, a limiting mounting groove is provided on the inner side of the through part 272. The limiting mounting groove can extend circumferentially along the through part 272. The limiting part 2721 can be constructed as a ring structure, and the limiting part 2721 can be fitted onto... The pressing part 271 and the limiting part 2721 are both located in the limiting installation groove, and the cross-sectional diameters of the pressing part 271 and the limiting part 2721 perpendicular to the axis of the fixing hole 244 are both larger than the diameter of the fixing hole 244. This allows the limiting part 2721 to be limited and pressed against the inner side of the earmuff accessory body 21, that is, the limiting part 2721 presses against the inner end of the fixing hole 244, and the pressing part 271 can be limited and pressed against the outer side of the earmuff accessory body 21, that is, the pressing part 271 presses against the outer end of the fixing hole 244.

[0079] Furthermore, the elastic element 28 is located between the pressing part 271 and the earcup accessory body 21. Thus, after pressing the pressing part 271, the operation button 27 moves towards the electronic control plate 26. After the through part 272 contacts the electronic control plate 26, the pressing part 271 simultaneously presses against the outer side of the earcup accessory body 21, restricting further movement of the operation button 27. After pressing, the operation button 27 moves away from the electronic control plate 26 until it reaches the limit part 2721, which presses against the inner side of the earcup accessory body 21, restricting further movement of the operation button 27 and allowing it to reset.

[0080] Therefore, through the above-mentioned settings, the pressing part 271 can limit the movement of the operation button 27 toward the electronic control board 26, which can prevent the operation button 27 from damaging the contact point of the electronic control board 26, thus improving safety. In addition, the limiting part 2721 can limit the movement of the operation button 27 away from the electronic control board 26, thus preventing the operation button 27 from coming off the ear cup accessory body 21.

[0081] In some embodiments, the outer side of the earmuff accessory body 21 is also provided with a mounting groove 245 for accommodating the pressing part 271. The bottom of the mounting groove 245 is connected to the fixing hole 244. The elastic member 28 is sleeved outside the through part 272. The elastic member 28 is located inside the mounting groove 245, and one end of the elastic member 28 abuts against the pressing part 271, and the other end abuts against the bottom wall of the mounting groove 245.

[0082] Specifically, as shown in Figure 6, the outer side of the earmuff accessory body 21 is provided with a mounting groove 245. The mounting groove 245 can be constructed as a circular groove. The mounting groove 245 can be concentrically set with the fixing hole 244, and the bottom of the mounting groove 245 is connected to the fixing hole 244, allowing the through part 272 to pass through the fixing hole 244. The pressing part 271 can be accommodated in the mounting groove 245. The inner diameter of the mounting groove 245 is larger than the outer diameter of the pressing part 271, and the mounting groove 245 is open to the outside of the earmuff accessory body 21 for the installation of the operation button 27. During installation, the elastic member 28 is located in the mounting groove 245 and sleeved on the outside of the through part 272. One end of the elastic member 28 abuts against the inner side of the pressing part 271, and the other end abuts against the bottom wall of the mounting groove 245, which realizes the arrangement of the elastic member 28. Its setting method is simple and easy to install.

[0083] The outer peripheral wall of the mounting groove 245 is provided with a pressing boss, which is used to press against the inner side of the pressing part 271. Alternatively, the outer end of the fixing hole 244 can be set as a pressing surface to press against the inner side of the pressing part 271. Both methods can achieve the limiting of the pressing part 271.

[0084] In some embodiments, a sealing member 273 is provided between the through part 272 and the inner wall of the fixing hole 244. The sealing member 273 is elastic and is pressed against the through part 272 and the fixing hole 244 to seal the fixing hole 244, preventing dust, water and other particles from entering the earmuff accessory 2. This keeps the inside of the earmuff accessory 2 dry and clean, ensuring the normal use of the earmuff accessory 2.

[0085] In the actual design, a sealing mounting groove is formed on the inner side of the through part 272. The sealing mounting groove extends circumferentially along the through part 272. The sealing mounting groove and the limiting mounting groove are distributed at intervals along the circumferential direction of the through part 272. The sealing element 273 can be constructed as a sealing ring. The sealing ring is fitted inside the sealing mounting groove and presses against the inner wall of the sealing mounting groove and the fixing hole 244. In this way, the reliability of the seal can be guaranteed.

[0086] In some embodiments, the earcup accessory 2 further includes a charging terminal 29, which is mounted on the earcup accessory body 21 and is at least partially exposed from the earcup accessory body 21, and is electrically connected to the electronic control board 26.

[0087] Specifically, the charging terminal 29 enables electrical connection. The charging terminal 29 is located on the outer side of the earcup accessory body 21. The outer side of the earcup accessory body 21 has a terminal mounting port 212 for mounting the charging terminal 29. The terminal mounting port 212 extends through both the inner and outer sides of the earcup accessory body 21, allowing at least a portion of the charging terminal 29 to be exposed on the earcup accessory body 21. The inner side of the charging terminal 29 is electrically connected to the electronic control board 26. Furthermore, as shown in Figures 4 and 5, the earcup accessory 21 also contains a battery 201, which can be connected to the electronic control board 26 to charge it.

[0088] Furthermore, when the earcup accessory 2 is low on power, the data cable of the external charging case can be connected to the charging terminal 29 to charge the earcup accessory 2. Once the power is fully charged, the data cable can be disconnected from the charging terminal 29.

[0089] Therefore, by setting the charging terminal 29, charging the earcup accessory 2 can be made simpler and more convenient.

[0090] In some embodiments, as shown in Figures 4 and 5, the charging terminal 29 and the operation button 27 are located on the same side of the earcup accessory body 21, and both the charging terminal 29 and the operation button 27 can be located on the outer side of the earcup accessory body 21, with at least a portion of their structure exposed on the earcup accessory body 21. This facilitates operation of the charging terminal 29 and the operation button 27. Their location on the same side of the earcup accessory body 21 saves space. Furthermore, the charging terminal 29 and the operation button 27 are simultaneously connected to the electronic control board 26, resulting in a more compact overall structure, simpler installation, and easier manufacturing. The spacing between the charging terminal 29 and the operation button 27 also prevents interference between their structures.

[0091] This application also proposes an earmuff structure 100.

[0092] The earmuff structure 100 according to an embodiment of this application includes: an earmuff body 1 and an earmuff accessory 2 according to any of the above embodiments. An open receiving groove 12 is formed on one side of the earmuff body 1, and at least a portion of the earmuff accessory 2 is received within the receiving groove 12. Therefore, through the above-described installation method, at least a portion of the earmuff accessory 2 can be embedded and installed in the earmuff body 1, concealing at least a portion of the earmuff accessory 2 within the receiving groove 12. Furthermore, since at least a portion of the earmuff accessory 2 extends into the earmuff body 1, the overlapping area between the two is increased, improving the connection strength between them.

[0093] Specifically, as shown in Figure 3, the earcup body 1 can be constructed as a circular structure. A receiving groove 12 is provided on the outer side of the earcup body 1. The receiving groove 12 can be a circular groove and is open to the outside. As shown in Figures 1 and 2, the size of the receiving groove 12 is larger than the outer size of the earcup accessory 2, which facilitates the installation of at least a portion of the earcup accessory 2 within the receiving groove 12. The earcup accessory 2 can also be completely accommodated within the receiving groove 12, which can improve the connection strength between the two and maintain the flatness of their surfaces. As shown in Figure 3, an ear pad 14 is provided on the side of the earcup body 1 away from the earcup accessory 2. The ear pad 14 can be detachably connected to the earcup body 1, allowing the ear pad 14 to be close to the ear when the user wears the earcup structure 100, providing wearing comfort.

[0094] In some embodiments, as shown in Figures 1-3, the earmuff body 1 is provided with a plurality of second magnetic elements 11 that cooperate with the first magnetic element 22. Among the plurality of second magnetic elements 11, the polarity of a portion of the second magnetic elements 11 facing the earmuff accessory 2 is different from that of another portion of the second magnetic elements 11 facing the earmuff accessory 2. The second magnetic elements 11 are magnetic. By providing a plurality of second magnetic elements 11 on the earmuff body 1, the magnetic connection between the earmuff body 1 and the earmuff accessory 2 can be realized. Furthermore, the connection strength of the earmuff body 1 can be improved through the adsorption effect of the plurality of second magnetic elements 11.

[0095] The second magnetic element 11 can be constructed as a magnet, and multiple second magnetic elements 11 are detachably connected to the earcup body 1.

[0096] Multiple second magnetic components 11 are magnetically attracted to multiple first magnetic components 22 in a one-to-one correspondence so that the earmuff accessory 2 can be detachably installed on the earmuff body 1. In this way, the earmuff accessory 2 and the earmuff body 1 can be magnetically connected. Moreover, multiple sets of magnetic attraction are achieved through multiple second magnetic components 11 and multiple first magnetic components 22, which can improve the connection strength between the earmuff accessory 2 and the earmuff body 1. The magnetic connection method makes the combination of the earmuff body 1 and the earmuff accessory 2 simpler and more convenient, and facilitates disassembly, maintenance and replacement.

[0097] Specifically, as shown in Figure 3, the earcup body 1 has multiple second magnetic elements 11 on the side near the earcup accessory 2, and the earcup accessory 2 also has multiple second magnetic elements 11 on the side near the earcup body 1. The polarities of the multiple second magnetic elements 11 facing the earcup accessory 2 are not all N or S poles, and at least one of the multiple second magnetic elements 11 has a different magnetic pole from the others. The arrangement of the multiple second magnetic elements 11 is the same as the arrangement of the multiple first magnetic elements 22. When two magnets are close together, they are affected by the magnetic repulsion of like poles and the attraction of unlike poles. Therefore, when the magnetic properties of the multiple second magnetic elements 11 and the multiple first magnetic elements 22 are different, the earcup accessory 2 and the earcup body 1 can attract each other and adhere together. In this embodiment, when the earcup accessory 2 is correctly installed onto the earcup body 1, each first magnetic element 22 is magnetically attracted to a corresponding second magnetic element 11.

[0098] In practical design, the number of first magnetic components 22 and second magnetic components 11 can be the same to ensure that each set of first magnetic components 22 and second magnetic components 11 can be attracted, avoiding waste of magnets. The number of second magnetic components 11 can be three, four, five, etc. Based on the magnetic polarity of the second magnetic components 11 facing the earcup accessory 2, at least one of the multiple second magnetic components 11 should be of opposite polarity. Alternatively, two, three, etc., can be set, and the number of opposite polarities of the earcup body 1 and the earcup accessory 2 should be the same to ensure reliable connection. The arrangement methods are diverse and can be flexibly selected.

[0099] Therefore, by setting multiple first magnetic components 22 and multiple second magnetic components 11 to magnetically attract each other in a one-to-one correspondence, the connection strength and stability between the earcup body 1 and the earcup accessory 2 are high. Furthermore, at least one of the multiple second magnetic components 11 has a different polarity than the others. Through the principle of like poles repelling and unlike poles attracting, the attraction direction between the earcup accessory 2 and the earcup body 1 is unique. If the earcup accessory 2 is misaligned, the first magnetic component 22 and the corresponding second magnetic component 11 cannot be accurately aligned and may even repel each other. In this way, magnetic connection and positioning installation can be achieved, preventing misalignment of the earcup accessory 2 and the earcup body 1 in the vertical and horizontal directions, thereby improving assembly accuracy and efficiency. The structure is simple, assembly is convenient, and the performance is excellent.

[0100] In some embodiments, a first magnetic element 22 and a second magnetic element 11 that are magnetically attracted to each other are defined as a group. When the earcup accessory 2 is misaligned and installed on the earcup body 1, at least one first magnetic element 22 engages with the second magnetic elements 11 of other groups, meaning that the first magnetic element 22 cannot engage with the corresponding second magnetic element 11. At this time, at least two first magnetic elements 22 and adjacent second magnetic elements 11 repel each other, thus making the user aware that the earcup accessory 2 is misaligned. In addition, even if the earcup accessory 2 is only slightly tilted during installation, the attraction between the first magnetic element 22 and the corresponding second magnetic element 11 can be used to adjust the earcup accessory 2 to the correct installation position. When the user wears the headphones, they cannot directly see the engagement direction between the earcup accessory 2 and the earcup body 1. By using the engagement of the first magnetic element 22 and the second magnetic element 11 to ensure that the earcup accessory 2 is installed correctly, the user can easily and accurately install the earcup accessory 2 onto the earcup body 1.

[0101] During installation, when the resultant force of the interaction between the multiple first magnetic components 22 and the second magnetic component 11 is a repulsive force, the earcup accessory 2 and the earcup body 1 cannot be magnetically attracted together, making the user aware that the earcup accessory 2 is misaligned. When the resultant force of the interaction between the multiple first magnetic components 22 and the second magnetic component 11 is an attractive force, the earcup accessory 2 and the earcup body 1 can be magnetically attracted together. However, the user can also judge whether the earcup accessory 2 is installed correctly by sensing the magnitude and direction of the resultant force between the earcup accessory 2 and the earcup body 1. When each first magnetic component 22 is magnetically attracted to its corresponding second magnetic component 11, the earcup accessory 2 and the earcup body 1 are connected. This connection is reliable, ensuring the accuracy of the installation of the earcup accessory 2 and the earcup body 1, thereby ensuring the normal use of the earcup structure 100. Furthermore, the installation method is simple, making it more convenient to use.

[0102] In some embodiments, an earcup space 13 is formed within the earcup body 1, and a plurality of second magnetic elements 11 are spaced apart and distributed on the sidewalls of the earcup space 13 near the receiving groove 12. In this embodiment, there are four second magnetic elements 11 spaced apart within the earcup space 13, and four first magnetic elements 22, with each of the four second magnetic elements 11 corresponding to one of the four first magnetic elements 22. The four second magnetic elements 11 are distributed near the sidewalls of the receiving groove 12, and the four first magnetic elements 22 are distributed near the receiving groove 12. This allows for reliable magnetic attraction between the four second magnetic elements 11 and the four first magnetic elements 22 during installation, ensuring that the structure of the earcup accessory 2 does not contact the inner bottom wall of the receiving groove 12. Furthermore, the evenly spaced distribution of the four second magnetic elements 11 within the earcup space 13 ensures uniform distribution of the attraction points between the earcup body 1 and the earcup accessory 2, thereby improving the stability of their connection.

[0103] In some embodiments, the depth of the receiving groove 12 is greater than or equal to half the thickness of the earmuff accessory 2. That is, the depth of the receiving groove 12 can be set to be greater than half the thickness of the earmuff accessory 2, and the depth of the receiving groove 12 can be set to be equal to half the thickness of the earmuff accessory 2. Both of these settings can accommodate at least a portion of the structure of the earmuff accessory 2 within the receiving groove 12. The settings are diverse and can be flexibly selected.

[0104] Therefore, this configuration allows for better compatibility between the two components, and the earcup accessory 2 and the earcup body 1 are assembled as shown in Figure 7.

[0105] In some embodiments, the earmuff structure 100 further includes an elastic buffer 3, which is disposed between the earmuff accessory 2 and the earmuff body 1.

[0106] Specifically, the elastic buffer 3 can be set on the earcup accessory 2, and the elastic buffer 3 can also be set on the earcup body 1. Both of these setting methods can achieve the buffering effect of the elastic buffer 3 between the earcup accessory 2 and the earcup body 1. The setting method is not unique and can be flexibly selected.

[0107] Furthermore, when the earcup accessory 2 is brought close to the earcup body 1, the two magnetic components 11 and the first magnetic components 22 attract and adhere to each other, while the elastic buffer 3 can elastically press against the earcup accessory 2 and the earcup body 1, thus achieving a tight installation of the earcup accessory 2 and the earcup body 1.

[0108] Therefore, since both the earcup body 1 and the earcup accessory 2 are plastic parts and have hard contact, a large knocking sound will occur during the magnetic attraction process. By setting the elastic buffer 3, the direct impact between the earcup accessory 2 and the earcup body 1 is avoided, and a certain buffering effect is achieved to alleviate and absorb the impact sound when the two are attracted, thereby reducing the installation noise. In addition, the elastic buffer 3 can play a sealing role after the earcup body 1 and the earcup accessory 2 are connected.

[0109] In some embodiments, the elastic buffer 3 is constructed as a ring-shaped member, extending circumferentially along the earcup accessory 2. Specifically, as shown in Figures 2 and 3, the elastic buffer 3 is connected to the side of the earcup body 1 closest to the earcup accessory 2, and extends circumferentially, corresponding to the outer periphery of the earcup accessory 2. This allows the elastic buffer 3 to completely cover the area where the earcup accessory 2 directly contacts the earcup body 1, achieving an elastic cushioning effect during installation. The elastic buffer 3 can be constructed as a silicone ring. Silicone has good elasticity and aging resistance, so when the earcup accessory 2 impacts the elastic buffer 3, the silicone ring can absorb the impact to provide a stable cushioning effect. Furthermore, the good elasticity of the silicone ring facilitates reuse.

[0110] Therefore, through the above-mentioned settings, the elastic buffer 3 can effectively cushion the earcup accessory 2 and the earcup body 1 during installation, thereby reducing installation noise and preventing wear between the earcup accessory 2 and the earcup body 1, thus extending the service life of the earcup accessory 2.

[0111] This application also proposes an earphone 1000.

[0112] The earphone 1000 according to the embodiments of this application includes a headband 200 and an earcup structure 100 of any of the above embodiments. There are two earcup structures 100, and the two earcup structures 100 are respectively connected to the two ends of the headband 200.

[0113] Specifically, in this embodiment, the headphone 1000 is configured as a headband headphone 1000, which includes a wired headphone 1000 and a wireless headphone 1000, as shown in Figure 7. The headband headphone 1000 includes a headband 200 and earcup structures 100, and there are two earcup structures 100. Each earcup structure 100 includes an earcup body 1 and an earcup accessory 2. The two earcup structures 100 are a left earcup structure and a right earcup structure, which are symmetrically distributed at both ends of the headband 200. The earcup bodies 1 of the left and right earcup structures can be connected to the headband 200 respectively, so that the headband headphone 1000 can be installed and the headband 200 can support the left and right earcup structures respectively, thereby fixing the two earcup structures 100.

[0114] Thus, the two earcup structures 100 are connected to the headband 200 as one unit, which facilitates the movement and wearing of the headphones 1000.

[0115] The left and right earcups 1 can be detachably connected to the headband 200 by bolts or other connectors, or by snap-fitting or other means.

[0116] In some embodiments, an earcup accessory 2 is detachably connected to each of the two earcup bodies 1 on opposite sides. This allows for a larger assembly space between the two earcup accessories 2 and the two earcup bodies 1, making it simpler and more convenient to disassemble and replace the earcup accessories 2 after the earcup bodies 1 are connected to the headband 200.

[0117] Specifically, the sides of the two earcup bodies 1 that are close to each other are called inner sides, and the sides of the two earcup bodies 1 that are away from each other are called outer sides. The two earcup bodies 1 are provided with receiving grooves 12 on the outer sides that are away from each other, and the two receiving grooves 12 are open in the direction away from each other. That is to say, the two receiving grooves 12 can be opened in the direction away from each other along the axial direction of the earcup structure 100. In this way, the two earcup accessories 2 can be installed in the two earcup bodies 1 respectively from the open sides of the two receiving grooves 12 in the direction that are close to each other. This connection allows the two earcup structures 100 to be symmetrically distributed at both ends of the headband 200. The earcup accessories 2 are detachable from the earcup bodies 1, so the earcup accessories 2 can be removed relative to the earcup bodies 1, which can realize the quick replacement of the earcup accessories 2 and reduce maintenance costs.

[0118] The two earcup accessories 2 are a left earcup accessory and a right earcup accessory. While the left and right earcup accessories have the same structure, they can also be distinguished as left and right. Specifically, when differentiating the left and right earcup structures 100, the positions of the magnets with opposite polarities between the left earcup accessory and the left earcup body, and between the right earcup accessory and the right earcup 1, can be set differently. This ensures specific magnetic attraction directions for the left and right sides, preventing the right and left earcup accessories from being installed incorrectly and improving the installation accuracy of the two earcup accessories 2. These different settings are suitable for different configurations of the headphones 1000, enabling different functions of the headphones 1000.

[0119] Therefore, the earmuff body 1 of the two earmuff structures 100 is provided with multiple second magnetic elements 11, some of which are reversed in direction with other second magnetic elements 11; the earmuff accessories 2 of the two earmuff structures 100 are provided with multiple first magnetic elements 22, some of which are reversed in direction with other first magnetic elements 22. By utilizing the principle of like poles repelling and unlike poles attracting between magnetic poles, the adsorption direction of the earmuff accessories 2 and the earmuff body 1 is unique, which can ensure that the relative positions of the earmuff body 1 and the earmuff accessories 2 are accurately installed, avoiding misalignment and preventing the two earmuff accessories 2 from being installed in reverse, thereby improving assembly accuracy and efficiency. Furthermore, through the one-to-one magnetic attraction of multiple sets of magnetic poles, the connection strength between the earmuff body 1 and the earmuff accessories 2 is high and the stability is good. The structure is simple, the assembly is convenient, and the performance is good.

[0120] The following description, with reference to Figures 1, 7, and 8-12, describes another aspect of the earmuff structure 100 according to an embodiment of this application. By setting a portion of a plurality of second magnetic elements 11 with different polarities from the other portion, and each first magnetic element 22 correspondingly attracting a second magnetic element 11, the principle of like poles repelling and unlike poles attracting between magnetic poles is utilized to ensure that the attraction direction between the earmuff accessory 2 and the earmuff body 1 is unique. This allows for accurate installation of the relative positions of the earmuff body 1 and the earmuff accessory 2, avoiding misalignment and thus improving assembly accuracy and efficiency. Furthermore, the one-to-one magnetic attraction of multiple sets of magnetic poles results in high connection strength and good stability between the earmuff body 1 and the earmuff accessory 2, with a simple structure, convenient assembly, and good performance.

[0121] As shown in Figures 8-12, an earmuff structure 100 according to an embodiment of this application includes: an earmuff body 1 and an earmuff accessory 2.

[0122] The earcup body 1 is provided with a plurality of second magnetic elements 11. The polarity of some of the second magnetic elements 11 facing the earcup accessory 2 is different from that of other second magnetic elements 11 facing the earcup accessory 2. The second magnetic elements 11 are magnetic. By providing a plurality of second magnetic elements 11 on the earcup body 1, magnetic connection between the earcup body 1 and other structures can be realized. Moreover, the connection strength of the earcup body 1 can be improved through the adsorption effect of the plurality of second magnetic elements 11.

[0123] The second magnetic component 11 can be constructed as a magnet. Multiple second magnetic components 11 are detachably connected to the earcup body 1. The earcup body 1 can be magnetically connected to other structures through multiple second magnetic components 11. The magnetic connection makes it easier and more convenient to combine the earcup body 1 with other structures, and facilitates disassembly, maintenance and replacement.

[0124] In order to accurately show the position of the second magnetic component 11, the internal circuitry and components of the earmuff body 1 are hidden in Figures 1 and 9 of this embodiment, so as not to obscure the second magnetic component 11.

[0125] The earmuff accessory 2 is provided with a plurality of first magnetic elements 22. Correspondingly, the polarity of a portion of the first magnetic elements 22 facing the earmuff body 1 is different from that of another portion of the first magnetic elements 22 facing the earmuff body 1. The first magnetic elements 22 are magnetic. By providing a plurality of first magnetic elements 22 in the earmuff accessory 2, magnetic connection between the earmuff accessory 2 and other structures can be realized. Furthermore, the connection strength of the earmuff accessory 2 can be improved through the adsorption effect of the plurality of first magnetic elements 22.

[0126] The first magnetic element 22 can be constructed as a magnet, and multiple first magnetic elements 22 can be detachably connected to the earmuff accessory 2.

[0127] Each first magnetic component 22 is respectively attracted to a corresponding second magnetic component 11, so that the earcup accessory 2 can be detachably installed on the earcup body 1. In this way, the earcup accessory 2 and the earcup body 1 can be magnetically connected. Multiple sets of magnetic attraction are achieved through multiple first magnetic components 22 and multiple second magnetic components 11, which can improve the connection strength between the earcup accessory 2 and the earcup body 1. The magnetic connection method makes the combination of the earcup body 1 and the earcup accessory 2 simpler and more convenient, and facilitates disassembly, maintenance and replacement.

[0128] Specifically, the earcup body 1 has multiple second magnetic elements 11 on the side near the earcup accessory 2, and the earcup accessory 2 has multiple first magnetic elements 22 on the side near the earcup body 1. Both the second magnetic elements 11 and the first magnetic elements 22 include N and S poles. The magnetic poles of some second magnetic elements 11 facing the earcup accessory 2 are different from those of other second magnetic elements 11 facing the earcup accessory 2. That is, not all second magnetic elements 11 have N or S poles facing the earcup accessory 2. Furthermore, the arrangement of the multiple first magnetic elements 22... The arrangement is the same as that of multiple second magnetic components 11. When two magnets are close, they are affected by the magnetic field repulsion between like poles and attraction between unlike poles. Therefore, when multiple first magnetic components 22 and multiple second magnetic components 11 meet with different magnetic properties, each first magnetic component 22 can be attracted to a corresponding second magnetic component 11. This allows the earmuff accessory 2 and the earmuff body 1 to attract each other and adhere together. When the earmuff accessory 2 is correctly installed on the earmuff body 1, each second magnetic component 11 is magnetically attracted to a corresponding first magnetic component 22.

[0129] In practical design, the number of second magnetic components 11 and first magnetic components 22 can be the same to ensure that each set of second magnetic components 11 and first magnetic components 22 can be attracted, avoiding waste of magnets. The number of second magnetic components 11 and first magnetic components 22 can be three, four, five, etc. Based on the magnetic polarity of the second magnetic components 11 facing the earcup accessory 2, at least one of the multiple second magnetic components 11 can be an opposite magnetic pole, or two, three, etc. can be set. Similarly, one of the multiple first magnetic components 22 can be an opposite magnetic pole, or two, three, etc. The number of opposite magnetic poles on the earcup body 1 and the earcup accessory 2 is the same to ensure reliable connection. The arrangement methods are diverse and can be flexibly selected.

[0130] Therefore, by setting multiple second magnetic components 11 and multiple first magnetic components 22 to magnetically attract each other in a one-to-one correspondence, the connection strength and stability between the earcup body 1 and the earcup accessory 2 are high. Furthermore, some of the second magnetic components 11 have different polarities than others, and each first magnetic component 22 is attracted to a corresponding second magnetic component 11. Based on the principle of like poles repelling and unlike poles attracting, the attraction direction between the earcup accessory 2 and the earcup body 1 is unique. If the earcup accessory 2 is misaligned, the second magnetic component 11 and the corresponding first magnetic component 22 cannot be accurately aligned and may even repel each other. This achieves magnetic connection and allows for precise positioning, preventing misalignment of the earcup accessory 2 and the earcup body 1 in the vertical or horizontal directions, thereby improving assembly accuracy and efficiency. The structure is simple, easy to assemble, and provides good performance.

[0131] In some embodiments, a first magnetic element 22 and a second magnetic element 11 that are magnetically attracted to each other are defined as a group. When the earcup accessory 2 is misaligned and installed on the earcup body 1, at least one first magnetic element 22 engages with the second magnetic elements 11 of other groups, meaning that the first magnetic element 22 cannot engage with the corresponding second magnetic element 11. At this time, at least two first magnetic elements 22 and adjacent second magnetic elements 11 repel each other, thus making the user aware that the earcup accessory 2 is misaligned. In addition, even if the earcup accessory 2 is only slightly tilted during installation, the attraction between the first magnetic element 22 and the corresponding second magnetic element 11 can be used to adjust the earcup accessory 2 to the correct installation position. When the user wears the headphones, they cannot directly see the engagement direction between the earcup accessory 2 and the earcup body 1. By using the engagement of the first magnetic element 22 and the second magnetic element 11 to ensure that the earcup accessory 2 is installed correctly, the user can easily and accurately install the earcup accessory 2 onto the earcup body 1.

[0132] During installation, when the resultant force of the interaction between the multiple first magnetic components 22 and the second magnetic component 11 is a repulsive force, the earcup accessory 2 and the earcup body 1 cannot be magnetically attracted together, making the user aware that the earcup accessory 2 is misaligned. When the resultant force of the interaction between the multiple first magnetic components 22 and the second magnetic component 11 is an attractive force, the earcup accessory 2 and the earcup body 1 can be magnetically attracted together. However, the user can also judge whether the earcup accessory 2 is installed correctly by sensing the magnitude and direction of the resultant force between the earcup accessory 2 and the earcup body 1. When each first magnetic component 22 is magnetically attracted to its corresponding second magnetic component 11, the earcup accessory 2 and the earcup body 1 are connected. This connection is reliable, ensuring the accuracy of the installation of the earcup accessory 2 and the earcup body 1, thereby ensuring the normal use of the earcup structure 100. Furthermore, the installation method is simple, making it more convenient to use.

[0133] In some embodiments, a receiving groove 12 is provided on the side of the earcup body 1, and at least a portion of the earcup accessory 2 is received within the receiving groove 12. Thus, through the above-described installation method, at least a portion of the earcup accessory 2 can be embedded and installed in the earcup body 1, concealing at least a portion of the earcup accessory 2 within the receiving groove 12. Furthermore, since at least a portion of the earcup accessory 2 extends into the earcup body 1, the overlapping area between the two is increased, improving their connection strength.

[0134] Specifically, as shown in Figures 9 and 10, the earcup body 1 can be constructed as a circular structure. A receiving groove 12 is provided on the outer side of the earcup body 1. The receiving groove 12 can be a circular groove that opens outwards. As shown in Figure 8, the size of the receiving groove 12 is larger than the outer dimensions of the earcup accessory 2, which facilitates the installation of at least a portion of the earcup accessory 2 within the receiving groove 12. Alternatively, the earcup accessory 2 can be completely accommodated within the receiving groove 12, which can improve the connection strength between the two and maintain the flatness of their surfaces.

[0135] As shown in Figure 10, the earcup body 1 has an ear pad 14 on the side away from the earcup accessory 2. The ear pad 14 can be detachably connected to the earcup body 1, so that when the user wears the earcup structure 100, the ear pad 14 is close to the ear, providing wearing comfort.

[0136] In some embodiments, the second magnetic element 11 is disposed near the inner bottom wall of the receiving groove 12, and the second magnetic elements 11 are spaced apart on a plane parallel to the inner bottom wall of the receiving groove 12. That is, the second magnetic elements 11 are spaced apart from the inner bottom wall of the receiving groove 12, and the second magnetic elements 11 are distributed in the outer peripheral area of ​​the inner bottom wall of the receiving groove 12. The second magnetic elements 11 are disposed on a plane parallel to the inner bottom wall. This ensures that the ends of the multiple second magnetic elements 11 near the ear cup accessory 1 are parallel, thereby ensuring that the multiple second magnetic elements 11 and the multiple first magnetic elements 22 are reliably attracted to each other in a one-to-one correspondence. Furthermore, since the inner bottom wall of the receiving groove 12 is the lowest point of the receiving groove 12, the multiple second magnetic elements 11 can be disposed on a plane in the outer region of the inner bottom wall of the receiving groove 12, which can shorten the length of the second magnetic elements 11 and reduce the installation cost of the second magnetic elements 11.

[0137] In this embodiment, there are four second magnetic elements 11, which are spaced apart and distributed on a plane near the inner bottom wall of the receiving groove 12. There are also four first magnetic elements 22, which are distributed one-to-one with the four second magnetic elements 11, as shown in Figure 9. All four second magnetic elements 11 protrude from the open side on the plane inside the receiving groove 12, allowing the four first magnetic elements 22 and the four second magnetic elements 11 to be directly attracted together. The structure of the earmuff accessory 2 does not contact the inner bottom wall of the receiving groove 12, which can keep the magnetic attraction between the earmuff accessory 2 and the earmuff body 1 reliable. The four second magnetic elements 11 are evenly spaced apart and distributed in the receiving groove 12, which can make the attraction points of the earmuff body 1 and the earmuff accessory 2 evenly distributed, thereby improving the stability of the connection between the two.

[0138] In some embodiments, the depth of the receiving groove 12 is greater than or equal to half the thickness of the earmuff accessory 2. That is, the depth of the receiving groove 12 can be set to be greater than half the thickness of the earmuff accessory 2, and the depth of the receiving groove 12 can be set to be equal to half the thickness of the earmuff accessory 2. Both of these settings can accommodate at least a portion of the structure of the earmuff accessory 2 within the receiving groove 12. The settings are diverse and can be flexibly selected.

[0139] Specifically, in this embodiment, as shown in Figure 9, the depth of the receiving groove 12 is set to be greater than half the thickness of the earcup accessory 2. For example, the depth of the receiving groove 12 can be set to 0.6 times, 0.8 times, etc., the thickness of the earcup accessory 2. With this setting, at least half of the structure of the earcup accessory 2 can be embedded into the receiving groove 12 in the installation direction. This can improve the connection strength between the two and keep their surfaces flat. The earcup accessory 2 and the earcup body 1 are assembled as shown in Figure 8. The depth setting of the receiving groove 12 is not unique and can be flexibly selected according to the usage requirements.

[0140] Furthermore, when the depth of the receiving groove 12 is the same as the thickness of the earmuff accessory 2, the structure of the earmuff accessory 2 can be fully embedded in the receiving groove 12 so that the external structural surfaces are flush after the two are connected, thus meeting the flatness requirement.

[0141] The receiving groove 12 is located in the middle of the earmuff body 1, which makes the overall structure of the earmuff body 1 more symmetrical and allows the earmuff accessory 2 to be connected to the middle of the earmuff body 1, making the overall structure more coordinated.

[0142] In some embodiments, an accessory cavity 23 is formed inside the earmuff accessory 2, and a first magnetic element 22 is located inside the accessory cavity 23, as shown in Figures 1 and 9. The accessory cavity 23 of the earmuff accessory 2 has an open side along the attraction direction for mounting the first magnetic element 22. The first magnetic element 22 extends along the attraction direction, and one end of the first magnetic element 22 is connected to the accessory cavity 23, which can realize the connection and fixation between the first magnetic element 22 and the earmuff accessory 2. The other end of the first magnetic element 22 is used for magnetic attraction with the second magnetic element 11, and at least a part of the structure of the first magnetic element 22 is located inside the accessory cavity 23. In this embodiment, multiple first magnetic elements 22 are spaced apart and distributed in the accessory cavity 23, and multiple first magnetic elements 22 are distributed in a one-to-one correspondence with multiple second magnetic elements 11, which can make the adsorption between the earmuff accessory 2 and the earmuff body 1 more reliable, thereby improving the stability of the connection between the two.

[0143] The spacing between the multiple first magnetic elements 22 is relatively large, which avoids the repulsive force between the multiple second magnetic elements 11 and between the multiple first magnetic elements 22, making the adsorption force between the multiple sets of magnetic poles more uniform, the magnetic adsorption effect better, and the installation operation simple and convenient.

[0144] The accessory cavity 23 can also be used to install other functional structures, such as electronic components.

[0145] In some embodiments, the earmuff accessory 2 includes a main body shell 24 and an accessory cover plate 25. The main body shell 24 is connected to the earmuff body 1, and the main body shell 24 defines an accessory groove 241 on the side opposite to the earmuff body 1. The accessory cover plate 25 is connected to the opening of the accessory groove 241 to close the accessory groove 241 and together define an accessory cavity 23.

[0146] Specifically, as shown in Figure 10, the earcup accessory 2 can be constructed as a circular structure. Both the main body shell 24 and the accessory cover plate 25 are circular. As shown in Figure 9, the main body shell 24 defines an accessory groove 241 on the side opposite to the earcup body 1. The accessory groove 241 can be constructed as a circular groove, and the accessory groove 241 is open to the outside. The accessory cover plate 25 is connected to the opening of the accessory groove 241, which can keep the accessory groove 241 in a closed state. The accessory groove 241 is closed by the accessory cover plate 25 to form an accessory cavity 23. In this way, the structure inside the accessory cavity 23 is hidden inside the earcup accessory 2, which can achieve the effect of protection and sealing, and can keep the outer structure of the earcup accessory 2 intact. In addition, the outer structure of the earcup accessory 2 is matched with the receiving groove 12 of the earcup body 1, which facilitates the connection between the two.

[0147] Furthermore, the main body shell 24 is used to connect with the earmuff body 1, and the earmuff accessory 2 can be detachably connected to the earmuff body 1, which can realize the sealing of the earmuff body 1, or realize other functions of combining the earmuff accessory 2 with the earmuff body 1.

[0148] It should be noted that the accessory cover 25 can be connected to the main shell 24 by means of adhesive bonding, snap-fit, etc., which is simple and convenient for assembly. Furthermore, the accessory cover 25 and the main shell 24 can be an integral structure, which reduces the connection steps and maintains their airtightness.

[0149] In some embodiments, the inner wall of the main body shell 24 is provided with a plurality of mounting posts 242, and the mounting posts 242 are provided with grooves 2421 for mounting the first magnetic element 22.

[0150] In this way, by setting multiple first magnetic components 22 to be installed in the grooves 2421 of multiple mounting posts 242 respectively, multiple first magnetic components 22 can be installed in the predetermined position, ensuring the accurate installation of the first magnetic components 22 in the main body shell 24, and facilitating the alignment of multiple first magnetic components 22 with multiple second magnetic components 11. The installation is convenient, the installation accuracy is high, and the maintenance and replacement of the first magnetic components 22 are convenient. Furthermore, the installation of the first magnetic components 22 in the mounting posts 242 can limit the outer periphery of the first magnetic components 22, avoiding accidental collisions and tilting. It has good structural strength and a long service life.

[0151] Specifically, as shown in Figure 9, multiple mounting posts 242 extend along the attraction direction within the main body shell 24. Each mounting post 242 has a groove 2421 for mounting the first magnetic component 22, and the groove 2421 is open towards the side closest to the earcup body 1. This allows one end of the first magnetic component 22 to be mounted in the groove 2421, while the other end protrudes from the end of the mounting post 242, thus enabling the multiple first magnetic components 22 to be well attracted to the multiple second magnetic components 11. The mounting posts 242 can be integrated with the main body shell 24, resulting in a simple structure and low processing cost.

[0152] In some embodiments, the main body shell 24 is provided with a plurality of reinforcing ribs 243, which intersect at the middle of the main body shell 24. The reinforcing ribs 243 divide the accessory cavity 23 into a plurality of sub-cavities 231, and each mounting post 242 is located in a different sub-cavity 231.

[0153] Specifically, the reinforcing ribs 243 can strengthen the structural strength of the main shell 24. As shown in Figure 9, multiple reinforcing ribs 243 and multiple mounting posts 242 are distributed on the same side of the main shell 24 and all protrude towards one side of the ear cup body 1. The multiple reinforcing ribs 243 extend towards the middle of the main shell 24 and cross and connect at the middle of the main shell 24. The multiple reinforcing ribs 243 are evenly distributed, making the overall structure more regular and orderly. The ends of the multiple reinforcing ribs 243 are connected to the inner sidewall of the main shell 24. In this way, the multiple reinforcing ribs 243 can support the inner bottom wall and inner sidewall of the main shell 24 to improve the structural strength of the main shell 24. The multiple reinforcing ribs 243 can divide the accessory cavity 23 into multiple sub-cavities 231 to accommodate multiple mounting posts 242.

[0154] There can be eight reinforcing ribs 243, which are evenly spaced apart along the circumference of the main shell 24. Mounting posts 242 are respectively provided in four of the sub-cavities 231. The number of reinforcing ribs 243 and the arrangement of mounting posts 242 are not limited to those described in this embodiment, and can be set according to actual needs.

[0155] In some embodiments, an elastic buffer 3 is provided between the earmuff accessory 2 and the earmuff body 1, and the elastic buffer 3 is connected to the earmuff accessory 2 or to the earmuff body 1.

[0156] Specifically, the elastic buffer 3 can be set on the earcup accessory 2, and the elastic buffer 3 can also be set on the earcup body 1. Both of these setting methods can achieve the buffering effect of the elastic buffer 3 between the earcup accessory 2 and the earcup body 1. The setting method is not unique and can be flexibly selected.

[0157] Furthermore, when the earcup accessory 2 is brought close to the earcup body 1, the multiple first magnetic elements 22 and multiple second magnetic elements 11 attract and adhere together, while the elastic buffer 3 can elastically press against the earcup accessory 2 and the earcup body 1, thus achieving a tight installation of the earcup accessory 2 and the earcup body 1.

[0158] Therefore, since both the earcup body 1 and the earcup accessory 2 are plastic parts and have hard contact, a large knocking sound will occur during the magnetic attraction process. By setting the elastic buffer 3, the direct impact between the earcup accessory 2 and the earcup body 1 is avoided, and a certain buffering effect is achieved to alleviate and absorb the impact sound when the two are attracted, thereby reducing the installation noise. In addition, the elastic buffer 3 can play a sealing role after the earcup body 1 and the earcup accessory 2 are connected.

[0159] It should be noted that the elastic buffer 3 can be connected to one of the earmuff accessories 2 and the earmuff body 1 through a glue, or it can be connected by a snap-fit ​​method, as long as the elastic buffer 3 is installed reliably. The elastic buffer 3 can be made of rubber, which has a good cushioning effect.

[0160] In some embodiments, the elastic buffer 3 is constructed as a ring, and the side edges of the earmuff accessory 2 facing the earmuff body 1 are abutted against the earmuff structure 100 by the elastic buffer 3.

[0161] Specifically, the annular component extends circumferentially along the earcup accessory 2, as shown in Figure 9. The elastic buffer 3 is connected to the side of the earcup body 1 near the earcup accessory 2, and extends circumferentially, corresponding to the outer periphery of the earcup accessory 2. This allows the elastic buffer 3 to completely cover the edge where the earcup accessory 2 and the earcup body 1 directly contact each other. The elastic buffer 3 elastically presses against both the earcup accessory 2 and the earcup body 1 to achieve an elastic cushioning effect during installation. The elastic buffer 3 can be constructed as a silicone ring. Silicone has good elasticity and aging resistance, so when the earcup accessory 2 impacts the elastic buffer 3, the silicone ring can absorb the impact to provide a stable cushioning effect. Furthermore, the good elasticity of the silicone ring facilitates reuse.

[0162] Therefore, through the above-mentioned settings, the elastic buffer 3 can effectively cushion the earcup accessory 2 and the earcup body 1 during installation, thereby reducing installation noise and preventing wear between the earcup accessory 2 and the earcup body 1, thus extending the service life of the earcup accessory 2.

[0163] In some embodiments, the earcup accessory 2 is a remote control, a decorative cover, a battery or data cable storage compartment. That is to say, there are many types of earcup accessories 2. The earcup accessory 2 can be configured as an integrated structure of a remote control, a decorative cover, a battery and a data cable storage compartment, or the earcup accessory 2 can be configured as a separate remote control, a decorative cover, a battery or a data cable storage compartment, etc.

[0164] When the earcup accessory 2 functions as a remote control, it allows users to directly control volume, switch songs, and answer calls on the earcup structure 100, making operation simple and convenient. When the earcup accessory 2 functions as a decorative cover, it serves a decorative purpose on the earcup structure 100, showcasing personalized design while maintaining the integrity of the earcup structure 100's exterior and protecting sensitive internal components from dust and damage. When the earcup accessory 2 functions as a battery, it provides power to the earcup structure 100, facilitating battery replacement when the battery is low or allowing for direct charging. When the earcup accessory 2 functions as a data cable storage compartment, it can have a built-in or attached data cable, allowing users to roll up and store the data cable inside the earcup structure 100, making it convenient to carry and helping to protect the data cable from damage.

[0165] Therefore, the connection between the remote control, decorative cover, battery or data cable storage compartment and the earcup body 1 can all be achieved by magnetic adsorption in this embodiment. Moreover, depending on the different earcup structures 100, the installation and disassembly of the earcup accessories 2 with different configurations are simpler and more convenient. The connection method is simple, the effect is good, and the applicability is wider.

[0166] This application also proposes another type of headphone 1000.

[0167] The earphone 1000 according to the embodiments of this application includes a headband 200 and an earcup structure 100 of any of the above embodiments. There are two earcup structures 100, and the two earcup structures 100 are respectively connected to the two ends of the headband 200.

[0168] Specifically, in this embodiment, the headphone 1000 is configured as a headband headphone 1000, which includes a wired headphone 1000 and a wireless headphone 1000, as shown in Figure 7. The headband headphone 1000 includes a headband 200 and earcup structures 100, and there are two earcup structures 100. Each earcup structure 100 includes an earcup body 1 and an earcup accessory 2. The two earcup structures 100 are a left earcup structure and a right earcup structure, which are symmetrically distributed at both ends of the headband 200. The earcup bodies 1 of the left and right earcup structures can be connected to the headband 200 respectively, so that the headband headphone 1000 can be installed and the headband 200 can support the left and right earcup structures respectively, thereby fixing the two earcup structures 100.

[0169] Thus, the two earcup structures 100 are connected to the headband 200 as one unit, which facilitates the movement and wearing of the headphones 1000.

[0170] The left and right earcups 1 can be detachably connected to the headband 200 by bolts or other connectors, or by snap-fitting or other means.

[0171] In some embodiments, an earcup accessory 2 is detachably connected to each of the two earcup bodies 1 on opposite sides. This allows for a larger assembly space between the two earcup accessories 2 and the two earcup bodies 1, making it simpler and more convenient to disassemble and replace the earcup accessories 2 after the earcup bodies 1 are connected to the headband 200.

[0172] Specifically, the sides of the two earcup bodies 1 that are close to each other are called inner sides, and the sides of the two earcup bodies 1 that are away from each other are called outer sides. The two earcup bodies 1 are provided with receiving grooves 12 on the outer sides that are away from each other, and the two receiving grooves 12 are open in the direction away from each other. That is to say, the two receiving grooves 12 can be opened in the direction away from each other along the axial direction of the earcup structure 100. In this way, the two earcup accessories 2 can be installed in the two earcup bodies 1 respectively from the open sides of the two receiving grooves 12 in the direction that are close to each other. This connection allows the two earcup structures 100 to be symmetrically distributed at both ends of the headband 200. The earcup accessories 2 are detachable from the earcup bodies 1, so the earcup accessories 2 can be removed relative to the earcup bodies 1, which can realize the quick replacement of the earcup accessories 2 and reduce maintenance costs.

[0173] The two earcup accessories 2 are a left earcup accessory and a right earcup accessory. While the left and right earcup accessories have the same structure, they can also be distinguished by left and right orientation. Specifically, when differentiating the left and right earcup structures 100, the positions of the magnets with opposite polarities between the left and right earcup accessories and the right earcup accessory can be set differently. This ensures specific magnetic attraction directions for the left and right sides, preventing reverse installation and improving the installation accuracy of the two earcup accessories 2. These different settings are suitable for different configurations of the headphones 1000, enabling different functionalities of the headphones 1000.

[0174] Therefore, the earmuff body 1 of the two earmuff structures 100 is configured with a portion of the second magnetic elements 11 having different polarities from the other portion, and each first magnetic element 22 is attracted to a corresponding second magnetic element 11. By utilizing the principle that like poles repel and unlike poles attract between magnetic poles, the attraction direction between the earmuff accessory 2 and the earmuff body 1 is unique, which can ensure that the relative positions of the earmuff body 1 and the earmuff accessory 2 are accurately installed, avoiding misalignment and thus improving assembly accuracy and efficiency. Furthermore, the one-to-one magnetic attraction of multiple sets of magnetic poles results in high connection strength and good stability between the earmuff body 1 and the earmuff accessory 2, with a simple structure, convenient assembly, and good performance.

[0175] In some embodiments, the earcup accessory 2 is a remote control, a decorative cover, a battery or data cable storage compartment. That is to say, there are many types of earcup accessories 2. The earcup accessory 2 can be configured as an integrated structure of a remote control, a decorative cover, a battery and a data cable storage compartment, or the earcup accessory 2 can be configured as a separate remote control, a decorative cover, a battery or a data cable storage compartment, etc.

[0176] When the earcup accessory 2 functions as a remote control, it allows users to directly control volume, switch songs, and answer calls on the earcup structure 100, making operation simple and convenient. When the earcup accessory 2 functions as a decorative cover, it serves a decorative purpose on the earcup structure 100, showcasing personalized design while maintaining the integrity of the earcup structure 100's exterior and protecting sensitive internal components from dust and damage. When the earcup accessory 2 functions as a battery, it provides power to the earcup structure 100, facilitating battery replacement when the battery is low or allowing for direct charging. When the earcup accessory 2 functions as a data cable storage compartment, it can have a built-in or attached data cable, allowing users to roll up and store the data cable inside the earcup structure 100, making it convenient to carry and helping to protect the data cable from damage.

[0177] Therefore, the connection between the remote control, decorative cover, battery or data cable storage compartment and the earcup body 1 can all be achieved by magnetic adsorption in this embodiment. Moreover, depending on the different earcup structures 100, the installation and disassembly of the earcup accessories 2 with different configurations are simpler and more convenient. The connection method is simple, the effect is good, and the applicability is wider.

[0178] This application also proposes a headphone system.

[0179] According to an embodiment of this application, the headphone system includes a charging case and the headphone 1000 described above. The charging case is used to charge the earcup accessory 2, which requires power. A battery can be built into the charging case to provide additional power to the earcup accessory 2 of the headphone 1000. In some embodiments, when the earcup accessory 2 is a remote control, the remote control is adapted to be electrically connected to the charging case 4 for charging. As shown in FIG11, a charging terminal 29 or a wireless charging port receiver can be provided on the remote control to facilitate charging of the remote control by the charging case 4. FIG12 shows a schematic diagram of the structure of the charging case 4. The top and bottom surfaces of the charging case 4 are both provided with recesses 42 for accommodating the remote control. The recesses 42 have contacts that mate with the charging terminal 29 of the remote control. The user can place the remote control to be charged in the recesses 42 of the charging case 4, and the charging case 4 charges the remote control through the charging terminal 29.
