Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0043] Please refer to Figures 1-4 The present utility model proposes an ear sleeve 10, wherein the ear sleeve 10 comprises a supporting piece 100, an ear sleeve body 200 and a sealing piece 300. Please refer to Figure 1 The ear sleeve 10 of the present utility model is of a ring structure and has an axis matching the ring structure, and the wearing direction of the ear sleeve 10 is parallel to the axis. When the ear sleeve 10 is worn behind the ear in the reverse direction of the wearing direction (the front direction in Figures 1-3 , and the reverse direction of the wearing direction is the rear direction in Figures 1-3 ), the ear sleeve 10 will wrap around the ear. It should be understood that the wearing direction of the present utility model refers to the direction in which the ear sleeve 10 is attached to the ear of the user when the user wears the ear sleeve 10, and the wearing direction is only a reference direction in the design and testing process of the ear sleeve 10, and does not mean that the user must strictly wear the ear sleeve 10 according to the wearing direction. For example, when the ear sleeve 10 is applied to an over-ear earphone, the wearing directions of the two ear sleeves 10 of the earphone are opposite, and in the actual wearing process of the ear sleeve 10, the posture of the ear sleeve 10 may be different due to different face shapes of people.

[0044] Please refer to Figures 3-5 The ear sleeve body 200 of the present utility model is connected to the supporting piece 100 and has a containing cavity 210, the containing cavity 210 is located on one side of the supporting piece 100 in the reverse direction of the wearing direction, one side of the ear sleeve body 200 in the wearing direction has a pressure relief hole 220, the containing cavity 210 is communicated with the outside through the pressure relief hole 220, and the pressure relief hole 220 is used for discharging the air in the containing cavity 210 when the ear sleeve body 200 is extruded. In the process of wearing the ear sleeve 10, the ear will extrude the ear sleeve body 200, and the air in the ear sleeve body 200 can be discharged through the pressure relief hole 220, so that the air pressure in the ear sleeve body 200 is reduced, the ear sleeve 10 is softer to wear, and a more comfortable use experience is provided for the user.

[0045] The containing cavity 210 of the ear sleeve body 200 of the present utility model can be used for containing different objects. Exemplarily, the containing cavity 210 is filled with flexible materials such as wool and fibers. As a preferred embodiment, please refer to Figure 3As shown, the ear sleeve 10 further comprises an elastic body 400, the ear sleeve body 200 wraps the elastic body 400, and the elastic body 400 is accommodated in the accommodation cavity 210. The elastic body 400 can provide elastic support force for the ear sleeve body 200, the ear sleeve 10 has stronger clamping effect on the human ear, further makes the wearing experience of the ear sleeve 10 more comfortable, and the elastic body 400 can adapt to the shape change of different human ears, can make the ear sleeve 10 closely fit the human ear, and is beneficial to enhancing the overall noise reduction effect of the earphone and providing better sound quality for the user. As a preferred embodiment, the elastic body 400 has pores inside. The pores inside the elastic body 400 can further enhance the softness of the elastic body 400 and provide better wearing experience. The manufacturing material of the above-mentioned elastic body 400 can be sponge, foam and the like.

[0046] It should be noted that when the ear sleeve 10 is extruded, the air in the pores of the elastic body 400 can also be discharged through the pressure relief hole 220, thereby reducing the air pressure in the elastic body 400, and the ear sleeve 10 is softer to wear, providing a more comfortable user experience.

[0047] The utility model does not limit the manufacturing process of the ear sleeve body 200. In some embodiments, the ear sleeve body 200 is formed by sewing. As a preferred embodiment, the ear sleeve body 200 is made by high-frequency technology. Using high-frequency technology to manufacture the ear sleeve body 200 can further improve the sealing performance of the ear sleeve body 200, reduce the accidental air leakage of the ear sleeve body 200, and improve the consistency of the ear sleeve 10 in low-frequency characteristics.

[0048] The utility model also does not limit the material of the ear sleeve body 200. For example, the ear sleeve body 200 can be made of leather, thermoplastic polyurethane elastomer, or polyurethane material. As a preferred solution, the ear sleeve body 200 is made of a composite film of microfiber cloth and plastic film. The above-mentioned composite material can further enhance the sealing performance of the ear sleeve body 200 and reduce the accidental air leakage of the ear sleeve body 200.

[0049] Based on the prior art, the utility model does not limit the specific function of the support 100. In related technology, the support is used to support the whole ear sleeve, and the shape of the support needs to be designed according to the actual assembly requirements of the ear sleeve and the specific shape of the ear sleeve.

[0050] However, the inventors have found in long-term work practice that the specific shape of the support needs to be designed into an irregular shape in order to achieve the corresponding function, and the pressure relief hole will deform irregularly due to the contact between the ear sleeve body 200 and the support 100. In the production process, the above-mentioned situation will further make it difficult to ensure the consistency of the low-frequency characteristics of different ear sleeves of the same model.

[0051] For the irregular deformation of the ear sleeve, specifically, the support of some ear sleeves in the prior art includes a clamping groove for clamping connection to the earphone support, and the clamping groove is notched on one side close to the pressure relief hole. When the ear sleeve is deformed, a part of the rim of the pressure relief hole of the ear sleeve is pressed by the edge of the notch, and the profile of the pressure relief hole of different ear sleeves is irregularly deformed due to the shape difference of the ear sleeve and the clamping groove. In some cases, the surface of the support for supporting part of the ear sleeve is relatively rough, so that when the rim of the pressure relief hole is pressed, irregular concave-convex is generated, and the profile of the pressure relief hole is uneven.

[0052] Please refer to Figures 3-5 The sealing piece 300 of the utility model is arranged between the ear sleeve body 200 and the support 100 in the wearing direction, and has a sealing plane 310 facing the ear sleeve body 200, and the sealing plane 310 blocks one side of the ear sleeve body 200 facing the wearing direction. The sealing plane 310 can block the ear sleeve body 200 and the support 100, and by blocking one side of the ear sleeve body 200 facing the wearing direction, the support 100 can be prevented from pressing the ear sleeve body 200 to cause the deformation of the pressure relief hole 220, and since the sealing plane 310 has good flatness, the part of the ear sleeve body 200 on one side in the wearing direction is limited by the sealing plane 310 and can remain flat, thereby making the profile of the pressure relief hole 220 on one side in the wearing direction less likely to change, reducing the shape difference between the profiles of the pressure relief holes 220 of different ear sleeves 10, reducing the difference in air permeability between different ear sleeves 10, and improving the consistency of the low-frequency characteristics of the same type of ear sleeve 10.

[0053] It should be noted that the sealing plane 310 of the utility model has multiple ways of blocking one side of the ear sleeve body 200 facing the wearing direction.

[0054] In some embodiments, the sealing plane 310 is attached to one side of the ear sleeve body 200 facing the wearing direction. When the ear sleeve 10 is pressed in the wearing direction, the flat surface of the sealing plane 310 can completely limit the part of the ear sleeve body 200 on one side in the wearing direction to be close to the support 100, thereby reducing the deformation of the profile of the pressure relief hole 220 and improving the consistency of the low-frequency characteristics of the ear sleeve 10. Without departing from the inventive concept of the utility model, a ventilation hole for communication with the sealing piece 300 can also be provided on the sealing piece 300, so that the air in the containing cavity 210 can flow out through the pressure relief hole 220 and the ventilation hole after the ear sleeve body 200 is pressed.

[0055] Please refer to Figure 4 , Figure 5As shown, in some embodiments, the pressure relief hole 220 forms a first opening 221 outside the ear sleeve body 200, and the sealing member 300 has a gap with the first opening 221 in the wearing direction. After the side of the ear sleeve body 200 opposite to the wearing direction is pressed, the edge of the first opening 221 gradually moves towards the sealing plane 310 and finally fits on the sealing plane 310. The sealing plane 310 limits the deformation of the pressure relief hole 220, improves the consistency of the ear sleeve 10 in low frequency characteristics, and in addition, when the edge of the first opening 221 has not yet fitted on the sealing plane 310, the ear sleeve body 200 can still discharge air through the pressure relief hole 220 during the pressing process, so that the air pressure inside the ear sleeve body 200 decreases, making the ear sleeve 10 wear softer and more comfortable.

[0056] On the basis of the above scheme, those skilled in the art can adjust the structure of the sealing member 300 so that the first opening 221 is closed when the edge of the first opening 221 fits on the sealing plane 310, so that the exhaust and intake amount of the pressure relief hole 220 is reduced when the ear sleeve body 200 is pressed to a certain extent, and the air content of the containing cavity 210 is more stable. The stable air content of the containing cavity 210 is conducive to the stable conduction of sound in the ear sleeve body 200, thereby providing the user with a more consistent auditory experience. Those skilled in the art can further adjust the gap between the first opening 221 and the sealing plane 310 according to the above scheme to adjust the exhaust amount of the ear sleeve body 200 during the pressing process, thereby adjusting the audio effect of the ear sleeve 10.

[0057] Please refer to Figure 5 Further, as shown, in some embodiments, the ear sleeve body 200 includes a wrapping member 230 and a tuning net 240, the wrapping member 230 has a containing cavity 210 and a pressure relief hole 220, the pressure relief hole 220 forms a second opening 222 on the side close to the containing cavity 210, and the tuning net 240 is connected to the wrapping member 230 and covers the second opening 222. The air in the containing cavity 210 needs to pass through the tuning net 240 when it is discharged through the pressure relief hole 220. The mesh structure of the tuning net 240 can hinder the discharge of air, thereby reducing the exhaust amount and increasing the gas content retained in the containing cavity 210, so that the ear sleeve 10 provides more resonant low frequency sound effects. Those skilled in the art can adjust the mesh number of the tuning net 240 according to the above scheme to adjust the exhaust amount of the ear sleeve body 200, and further adjust the audio effect of the ear sleeve 10.

[0058] Please refer to Figures 5-7As shown, further, in some embodiments, the sealing member 300 is annular in structure, the axis of the sealing member 300 is parallel to the axis of the ear sleeve 10, the part of the sealing member 300 away from the axis of the sealing member 300 is connected to the ear sleeve body 200, and the part of the sealing member 300 close to the axis of the sealing member 300 is spaced apart from the first opening 221 in the wearing direction. The annular sealing member 300 can better match the structure of the annular ear sleeve 10, thereby improving the structural strength of the sealing member 300. On the other hand, in the wearing process, with the part of the ear sleeve body 200 connecting the sealing member 300 as the reference, the user's ear will extrude the part of the ear sleeve body 200 close to the axis in the wearing direction, the part of the ear sleeve body 200 close to the axis of the ear sleeve 10 will deform more quickly toward the sealing plane 310, and the edge of the first opening 221 close to the axis of the ear sleeve 10 will more easily approach and fit the sealing plane 310, so that the overall deformation of the ear sleeve body 200 is smaller, and the pressure relief hole 220 is also less likely to deform due to the overall deformation of the ear sleeve body 200, thereby facilitating the improvement of the consistency of the profile of the pressure relief hole 220.

[0059] For the convenience of those skilled in the art, please refer to Figure 4 , Figure 5 As shown, exemplarily, in the wearing process, relative to the part of the ear sleeve body 200 connecting the sealing member 300, the user's ear is more likely to extrude the part of the ear sleeve body 200 close to the axis, so that the part of the ear sleeve body 200 close to the axis deforms more quickly toward the sealing plane 310, and the edge of the first opening 221 close to the axis is more easily close to and fit the sealing plane 310. Figure 4 As shown, exemplarily, in the wearing process, relative to the part of the ear sleeve body 200 connecting the sealing member 300, the user's ear is more likely to extrude the part of the ear sleeve body 200 close to the axis, so that the part of the ear sleeve body 200 close to the axis deforms more quickly toward the sealing plane 310, and the edge of the first opening 221 close to the axis is more easily close to and fit the sealing plane 310.

[0060] Without departing from the inventive concept of the present application, those skilled in the art can provide a plurality of pressure relief holes 220 on the ear sleeve 10, so as to adjust the exhaust capacity of the ear sleeve 10.

[0061] On the basis of the above scheme, please refer to Figure 5 , Figure 7As shown, in some embodiments, the sealing plane 310 can be in contact with the edges of the plurality of first openings 221 after the side of the earphone body 200 opposite to the wearing direction is pressed. The edges of the plurality of first openings 221 being in contact with the same sealing plane 310 at the same time facilitates the deformation of the plurality of pressure relief holes 220 to be as consistent as possible after the edges of the plurality of first openings 221 are in contact with the same sealing plane 310, so that the air permeability of the plurality of pressure relief holes 220 can also be as consistent as possible, which facilitates the person skilled in the art to adjust the overall air permeability of the earphone 10, so as to more conveniently adjust the audio characteristics of the earphone 10. On the other hand, the edges of the plurality of first openings 221 being in contact with the same sealing plane 310 also facilitates the reduction of the number of sealing members 300, so as to simplify the assembly of the earphone 10.

[0062] In some embodiments, the earphone body 200 has a plurality of pressure relief holes 220, the earphone 10 comprises a plurality of sealing members 300, and the edge of each first opening 221 can be close to and in contact with a different sealing plane 310 after the side of the earphone body 200 opposite to the wearing direction is pressed. When there is a problem in the contact or assembly between the pressure relief holes 220 and the sealing members 300, the edges of the plurality of first openings 221 being in contact with different sealing planes 310 facilitates the person skilled in the art to adjust or replace the sealing members 300 individually, so as to facilitate the person skilled in the art to improve the contact degree of the pressure relief holes 220 and the sealing planes 310. On the other hand, the above-mentioned scheme also facilitates the reduction of the overall material of the sealing members 300, so as to reduce the material cost of the earphone 10.

[0063] Without departing from the inventive concept of the present application, the person skilled in the art can adjust the arrangement of the plurality of pressure relief holes 220. In some embodiments, the angle formed by the center of each pressure relief hole 220 and the axis of the earphone 10 in the plane perpendicular to the axis of the earphone 10 is the same. The pressure relief holes 220 of the above-mentioned scheme can further reduce the difference in air exhaust amount of different regions of the earphone 10 when the earphone 10 is pressed.

[0064] Please refer to Figure 1 , Figure 7As shown, as a preferred solution, in some embodiments, the ear sleeve body 200 has a plurality of pressure relief holes 220, two of which are located on a straight line perpendicular to the axis of the ear sleeve 10, and the straight line intersects the axis of the ear sleeve 10; and one is located on one side of the axis of the ear sleeve 10 in a first direction, and the other is located on the other side of the axis of the ear sleeve 10 in the reverse direction of the first direction, which is perpendicular to the wearing direction. On the basis of reducing the exhaust amount of different areas of the ear sleeve 10, due to the annular structure of the ear sleeve 10, arranging two pressure relief holes 220 on both sides of the axis of the ear sleeve 10 in the above manner can reduce the distance from each part of the containing cavity 210 to the pressure relief hole 220, which is beneficial to quickly exhaust air when the ear sleeve 10 is pressed, thereby increasing the air permeability of the ear sleeve 10, the air pressure in the containing cavity 210 is lower, and the ear sleeve 10 is more comfortable to wear.

[0065] Please refer to Figure 7 As shown, as a preferred arrangement, in some embodiments, the ear sleeve body 200 defines an oblate channel for accommodating a human ear, and the arc-shaped wall surface of the oblate channel is distributed along the up-down direction of the human ear, and the two pressure relief holes 220 are located on both sides of the up-down direction. The above scheme is more conducive to the exhaust of the pressure relief hole 220, so that the wearing effect of the ear sleeve 10 is better.

[0066] Without departing from the inventive concept of the present application, the present application does not limit the connection mode between the ear sleeve body 200 and the support 100. In some embodiments, please refer to Figures 3-5 As shown, the sealing member 300 is glued to the side of the ear sleeve body 200 facing the wearing direction (i.e. Figures 3-5 As shown, the support 100 is glued to the side of the sealing member 300 facing the wearing direction. Using glue to connect the support 100 is beneficial to simplify the structural design of the ear sleeve 10, and thereby reduce the overall volume of the ear sleeve 10.

[0067] Please refer to Figure 4 As shown, further, the ear sleeve 10 further comprises an extension 500, which is integrally connected to the ear sleeve body 200 and protrudes from the side of the ear sleeve body 200 facing the wearing direction, and is connected to the side of the support 100 facing the wearing direction. The ear sleeve body 200 in the above embodiment is indirectly connected to the support 100 through the extension 500 and the sealing member 300, the connection between the ear sleeve body 200 and the support 100 is stronger, the structure of the ear sleeve 10 is more stable, and the durability is improved.

[0068] Please refer to Figures 1-7 As shown, Figures 1-7The earphone support does not show the earphone, and the utility model discloses an earphone, including earphone support and the ear sleeve 10 of any one of the above embodiment, the support piece 100 of ear sleeve 10 is sealedly connected to the earphone support. The sealing plane 310 can block the support piece 100 and the ear sleeve body 200, by shielding the side of the ear sleeve body 200 towards the wearing direction, the support piece 100 can be prevented from extruding the ear sleeve body 200 to cause the deformation of the pressure relief hole 220, and since the sealing plane 310 has good flatness, the part of the ear sleeve body 200 on the side of the wearing direction is limited by the sealing plane 310 and can keep flat, thereby making the contour of the pressure relief hole 220 on the side of the wearing direction more difficult to change, reducing the shape difference between the contours of the pressure relief holes 220 of different ear sleeves 10, reducing the air permeation difference between different ear sleeves 10, and the consistency of the low-frequency characteristics of the same model of ear sleeve is higher. And since the earphone support is sealedly connected to the support piece 100, the sound of the earphone is less likely to leak out from the connection between the support piece 100 and the earphone support, thereby improving the auditory experience of the user.
