Of course, in other embodiments, the earphone body 200 may not have the mouthpiece 210, and the ear cap 300 may be detachably connected to the earphone body 200.

Reference may be made to the following detailed description of embodiments of the ear cap 300 of the present application regarding the ear cap 300 of the present embodiment.

The present ear cap embodiments describe at least one exemplary configuration of the ear cap 300.

As shown in fig. 4-7, the ear cap 300 can include a cap post 310 and a cap sleeve 320. The cap post 310 and the cap 320 are coupled to each other.

As shown in fig. 5, the cap pillar 310 may be formed with a sound guide passage 311 extending through both ends thereof, and a passage outlet 312 and a passage inlet 313 respectively formed between opposite ends of the cap pillar 310. In other words, the sound guide passage 311 may have a passage outlet 312 and a passage inlet 313 at both ends of the cap post 310. The mouthpiece 210 of the earphone body 200 may be inserted into the sound guide channel 311 through the channel inlet 313.

Alternatively, the shape of the sound guide channel 311 in a cross section perpendicular to the longitudinal direction thereof may be circular, racetrack, or other shapes.

Alternatively, the sectional area of the sound guide channel 311 in the above section may be constant and gradually reduced in the direction from the channel inlet 313 to the channel outlet 312, while the sectional area of the channel outlet 312 is minimized. Taking the cross-sectional shape of the sound guide channel 311 as a circle, the diameter of the sound guide channel 311 is the largest at the channel inlet 313 in the direction from the channel inlet 313 to the channel outlet 312, and then gradually becomes smaller after keeping the largest diameter for a certain length in the length direction of the cap post 310, and the diameter of the channel outlet 312 is the smallest. Of course, the sound guide channel 311 may have the largest cross-sectional area at any predetermined position between the channel inlet 313 and the channel outlet 312, for example, an annular groove (not shown) may be further disposed in the sound guide channel 311, the sound mouth 210 may be provided with a latch (not shown) matching with the annular groove, and the sound mouth 210 is latched with the annular groove when inserted into the sound guide channel 311.

As shown in fig. 5, the cap 320 may be sleeved on the outer circumference of the cap post 310. Specifically, the cap 320 may include a case body 321 and a connection portion 322. The sleeve body 321 can be sleeved on the outer circumference of the cap pillar 310. The sleeve body 321 may be provided, for example, in the form of an annular body, and may be further provided in the form of an umbrella-shaped annular body with an open top. The first end of the sleeve body 321 may be opened with sound outlet holes 323 opposite to the channel outlet 312 and spaced from each other. The sound generated from the earphone 20 may be transmitted to the outside through the passage outlet 312 and the sound outlet hole 323, and may be transmitted into the ear canal of the user through the sound outlet hole 323 when being worn in the ear canal of the user. A second end of the sleeve body 321 (i.e., the end away from the sound outlet hole 323) may have an opening 324 opposite to the channel inlet 313 and spaced apart from each other. In other words, the sleeve body 321 can be sleeved on the outer periphery of the cap pillar 310, and the cap pillar 310 is located between the sound outlet 323 and the opening 324. The opening 324 may expose the channel entrance 313, and the mouthpiece 210 may be inserted into the channel entrance 313 from the opening 324 and then fixed to the cap post 310, thereby mounting the earcap 300 on the earphone 20.

The user can wear the headset 20 with the earcap 300 mounted to his ear. When the earphone 20 is inserted into the ear canal of the user, the sleeve body 321 can be pressed against the ear canal of the user through deformation, and friction force exists between the sleeve body 321 and the ear canal, so that the stability of the earmuff can be better maintained, and the wearing stability of the earphone 20 is further enhanced.

As shown in fig. 5, the connecting portion 322 is connected between the cap post 310 and the covering 321. Specifically, the connecting portion 322 includes a first end and a second end that are disposed opposite to each other, the first end of the connecting portion 322 is connected to the cap pillar 310, and the second end of the connecting portion 322 is connected between the first end of the cover 321 that encloses the sound outlet 323 and the second end that is far away from the sound outlet 323. Further, a first end of the connection portion 322 is connected to a first end of the cap post 310 (i.e., the end provided with the channel outlet 312). Specifically, the second end of the connecting portion 322 is connected between two ends of the sheath body 321. Alternatively, the second end of the connecting portion 322 is located at the middle section of the sheath body 321, for example, the middle section may be an interval portion of 1/3 to 2/3 of the length of the sheath body 321 in the length direction thereof. In the present embodiment, the connecting portion 322 is connected between the cap pillar 310 and the covering 321, and the cap pillar 310 and the covering 321 can be spaced apart to form a buffer space 325 which communicates the passage outlet 312 and the sound outlet hole 323 and is at least partially located between the passage outlet 312 and the sound outlet hole 323. For example, the wall body (e.g., the first wall body 3211) of the sleeve body 321 between the sound outlet hole 323 and the connection part 322 enclose a buffer space 325 between the communication passage outlet 312 and the sound outlet hole 323, so that the cap 320 can move and/or deform relative to the cap post 310 to adapt to different ear canal structures. In other words, the passage outlet 312 and the sound outlet 323 are spaced and stacked, and a gap is formed between the passage outlet and the sound outlet by the first wall 3211 and the connection 322. The first wall 3211 of the sleeve body 321 located between the sound outlet 323 and the connecting portion 322 forms a "folded structure" with the connecting portion 322, and the folded structure forms the buffering space 325.

Further, the connection portion 322 connects the sheath body 321 and the cap pillar 310 to space the sheath body 321 and the cap pillar 310 to form the buffer space 325 and the support space away from the buffer space 325, which are spaced or independent from each other. Specifically, the sleeve body 321 is sleeved on the outer periphery of the cap post 310. Therefore, the wall (e.g., the second wall 3212) of the sleeve 321 between the connecting portion 322 and the opening 324 and the cap post 310 are spaced apart from each other to form a supporting space 326. The supporting space 326 allows deformation, i.e., lateral deformation, between the portion of the sheath 321 near the second end thereof and the cap post 310. When worn, the portion of the sheath 321 near the second end thereof is compressed and gathered toward the cap post 310. Due to this deformation, the sleeve body 321 exerts a corresponding force in the lateral direction against the ear canal of the user, and thus against the ear canal of the user.

The first end of the connecting part 322 is connected with the cap column 310, the second end of the connecting part 322 is connected between two ends of the sleeve body 321, the sleeve body 321 is positioned between the first wall body 3211 between the sound outlet hole 323 and the connecting part 322 encloses a buffer space 325 which is communicated with the channel outlet 312 and the sound outlet hole 323, the buffer space 325 can form a buffer area/deformation area between the channel outlet 312 and the sound outlet hole 323, so that the earcap 300 has better ear canal adaptability, for example, the deformable characteristic of the earcap 300 in the height direction (also in the inserting direction) can be effectively increased, so that the height of the earcap 300 can adapt to the different ear canal structures and adaptively resist the change, and the position and the orientation of the sound outlet hole 323 can adapt to the ear canal structures and generate corresponding change, thereby being capable of adapting to various ear canal structures of a wider user, and the adaptive deformation due to the adaptive ear canal structure, after the earcap 20 is worn, the adaptive deformation of the earcap 300 can better resist the ear canal structure, the contact area of the sleeve body of the earcap 300 and the ear canal is increased, thereby improving the stability of the earphone 300 and the wearing comfort of the earcap and the earphone 300 can be improved.

Optionally, the first end of the connection portion 322 is connected to the first end of the cap pillar 310, that is, the end of the cap pillar 310 where the channel outlet 312 is opened. As shown in fig. 5, in a cross-section passing through the central axis of the cap post 310, an angle α between a line connecting the first end and the second end of the connection portion 322 and the central axis of the cap post 310 is 0 ° to 180 °. That is, the included angle α ranges from 0 to 180 °. In the present embodiment, 0 ° to 180 ° may mean more than 0 ° and less than 180 °. The same applies to other numerical ranges mentioned in this embodiment.

The included angle α is the included angle of the ear cap 300 in its natural, unworn or non-squeezed state. In the present embodiment, the included angle α is an included angle between the connecting portion 322 and a central axis of the cap column 310, and the central axis of the cap column 310 may be an axis passing through a geometric center/a geometric center of gravity of the channel outlet 312 and the channel inlet 313, or a symmetry axis of the cap column 310. The connecting portion 322 may be a truncated cone having a central axis and two open ends, and at this time, a generatrix of the truncated cone is a straight line; in other embodiments, the bus bar may be a curved line, for example, a wave-shaped curved line, and the connecting portion 322 is a three-dimensional structure formed by the curved line and the bus bar rotating around its central axis, in which case, an included angle formed between a straight line formed by connecting the first end and the second end of the connecting portion 322 and the central axis of the cap pillar 310 may be used as the included angle α.

The value range of the included angle alpha can be further selected from 0 degree to 80 degrees, or can be selected from 10 degrees to 70 degrees, or can be selected from 10 degrees to 50 degrees, or can be selected from 0 degree to 40 degrees, or can be selected from 0 degree to 170 degrees, or can be selected from 10 degrees to 150 degrees, or can be selected from 10 degrees to 80 degrees, or can be selected from 100 degrees to 180 degrees, or can be selected from 30 degrees to 120 degrees, or can be selected from 60 degrees to 110 degrees.

As mentioned above, the sound emitting hole 323 and the passage outlet 312 are disposed opposite to each other. Alternatively, as shown in fig. 4, the cap pillar 310 is provided with a first end of the passage outlet 312, and an orthographic projection of at least part of the connecting portion 322 on the plane of the sound outlet hole 323 is located inside the sound outlet hole 323, so that the first end of the cap pillar 310 provided with the passage outlet 312 and at least part of the connecting portion 322 are exposed through the sound outlet hole 323.

Optionally, the area of the sound emitting hole 323 is larger than the area of the channel outlet 312 to be able to expose at least a portion of the first end of the cap pillar 310 and/or at least a portion of the connection portion 322 through the sound emitting hole 323. The area of the sound outlet hole 323 is larger than the area of the passage outlet 312, so that at least a portion of the first end of the cap pillar 310 and/or at least a portion of the connecting portion 322 may be exposed through the sound outlet hole 323, and after the portions are exposed, dust, earwax, etc. entering through the sound outlet hole 323 may fall into the buffering space 325, or enter into the buffering space 325 through the exposed portion of the first end of the cap pillar 310, and then be carried on the connecting portion 322 or the first wall body 3211, thereby reducing dust, earwax, etc. falling to the mouthpiece 210. Of course, in other embodiments, the area of the sound emitting hole 323 may be smaller than or equal to the area of the channel outlet 312, as long as the first end of the cap pillar 310 and at least a portion of the connection portion 322 can be exposed through the sound emitting hole 323.

As shown in fig. 4, the projection of the passage outlet 312 on the plane of the sound output hole 323 falls into the sound output hole 323. Due to the arrangement, the sound outlet 323 faces to a part of the cap post 310 and/or a part of the connecting part 322 in the corresponding range inside the earcap 300, and the sound outlet 323 can be exposed, so that dust, earwax and the like can fall on the cap post 310 and/or the connecting part 322 around the sound outlet 323 with a high probability, and the connecting part 322 can better bear the dust, earwax and the like falling to the buffer space 325.

Alternatively, the sound outlet hole 323 and the passage outlet 312 are coaxially disposed. For example, the axis of the sound emitting hole 323 may refer to an axis passing through the geometric center/geometric center of the sound emitting hole 323 and perpendicular to the plane in which the sound emitting hole 323 is located. Similarly, the axis of the channel outlet 312 may refer to an axis passing through the geometric center/centroid of the channel outlet 312 and perpendicular to the plane of the channel outlet 312. Further, the sound outlet 323 and the passage outlet 312 are coaxially disposed with the central axis of the cap pillar 310 as an axis, that is, the axes of the sound outlet 323 and the passage outlet 312 are both coincident with the central axis of the cap pillar 310.

As shown in fig. 5, the vertical distance g between the plane of the sound outlet 323 and the plane of the channel outlet 312 may be in the range of 0.7mm to 2.5mm. Alternatively, the vertical distance g may be 0.8mm to 2.3mm. Alternatively, the distance g may be 0.92mm to 2.26mm. Alternatively, the vertical distance g may be 1mm to 2.2mm. Optionally, the distance g can be set to provide the effective compressible performance of the buffering space 325 in the axial direction, so that the deformation is easier and more free, the adaptive effect is better, and discomfort caused by forced extrusion of the earcap 300 to the ear canal can be effectively reduced when the earcap is worn, and the distance g neither makes the volume of the buffering space 325 too large to influence the acoustic performance, nor makes the volume of the buffering space 325 too small to influence the wearing comfort and the adaptive performance, nor makes dirt such as earwax block the opening of the buffering space 325. As shown in fig. 6, when the buffering space 325 is compressed in the axial direction or the radial direction, the vertical distance g is decreased, and the size of the buffering space 325 is changed accordingly, so as to adapt to different structures and/or sizes of different ear canals, thereby achieving the self-adaptive effect.

Alternatively, in the case of the coaxial arrangement, the area of the sound outlet hole 323 is larger than the area of the passage outlet 312, or it can be said that the radial maximum size of the sound outlet hole 323 is larger than the radial maximum size of the passage outlet 312. Optionally, the area of sound outlet 323 compares in the area of passageway export 312 the ratio can be 1.05 ~ 3, so can make buffer space 325 can play better and hide the dust, cerumen etc. effect, can reduce the phenomenon that cerumen etc. fell into passageway export 312 effectively, and then reduce cerumen and block up passageway export 312 and to the influence of sound effect, and through the beta structure that sets up connecting portion 322 and form, can conveniently turn over towards outside the book to the part that encloses of cover body 321 and form buffer space 325, and then can wash cerumen, dust etc., easy operation and swift.

For example, the sound emitting hole 323 and the passage outlet 312 are both circular, and the diameter (i.e., the maximum diameter) of the sound emitting hole 323 is larger than the diameter (i.e., the maximum diameter) of the passage outlet 312. Further, the ratio of the diameter of the sound outlet hole 323 to the diameter of the passage outlet 312 may be 1.05 to 2.7. This makes it easier for dust, earwax, etc. to fall onto the cap pillar 310 and/or the connection portion 322 around the sound outlet hole 323, so that the connection portion 322 can better carry the dust, earwax, etc. falling into the buffer space 325. When the sound emission hole 323 has an irregular circular shape, the maximum diameter of the sound emission hole 323 is larger than the diameter of the passage outlet 312 having a regular circular shape or the maximum diameter of the passage outlet having an irregular circular shape.

As can be seen from the above description, the buffering space 325 and the connecting portion 322 can bear cerumen, and can hide the cerumen. The earcap 300 can be removed from the mouthpiece 210 to facilitate cleaning of the earcap 300, and thus the earcap 300 can be considered to have an anti-cerumen effect.

In this embodiment, the material of the ear cap 300 may be silicone, or the material of the ear cap 300 includes silicone. The cap post 310 and the cap 320 may be integrally formed, or may be separately structured and later connected.

Based on the above description, as shown in fig. 6, the ear cap 300 of the present embodiment can realize multi-dimensional deformation in the height direction (the central axis of the cap post 310 in fig. 5) and the lateral direction (the direction perpendicular to the height direction), so as to better adapt to different ear canal structures, and make the wearing stability and the sealing performance better, and the adaptive function of the ear cap 300 is further described below from the perspective of different ear structures.

For ears with smaller concha cavities: wearing an earcap as mentioned in the related art may be held against the antitragus. When the ear cap 300 described in the present embodiment is worn, the shape of the ear cap 300 deforms with force, and the cushion space 325 is correspondingly moved and/or deformed by the simultaneous force applied to the covering 321 and the connecting portion 322, thereby shortening the effective length of the ear cap 300 in contact with the ear canal.

For a moderate ear with a concha cavity: when the earcap 300 described in this embodiment is inserted into the ear canal, the sheath 321 and the connecting portion 322 generate at least two forces: firstly, the effort that the deformation of direction of height produced, secondly the effort that the deformation of lateral side produced, improved the comfort level when so guaranteeing stability and the leakproofness of wearing under the effect of two gravity.

For ears with a large concha cavity: since the force point of the earphone 20 and the ear is mostly at the earcap 300 after wearing, the earcap is liable to fall off as mentioned in the aforementioned related art. After the earcap 300 of the present embodiment is worn, the earcap can generate dual acting forces, so that the earcap is more tightly fitted to the ear canal, and the friction force is greater, so that the earphone 20 is less likely to fall off when worn.

Through the above description, as shown in fig. 6, owing to set up connecting portion 322, and then form buffer space 325 between the cover body 321 and connecting portion 322 for earcap 300 not only can be in the side direction deformation, can also be in the direction of height deformation, and the deformation of two kinds of not equidirectional can support the duct better to the power of producing to the duct, has greatly strengthened the adaptability to the duct, promotes and wears stability and comfort level.

Moreover, as shown in fig. 7, since the ear cap 300 can be deformed in the lateral direction and the height direction, during the actual insertion process into the ear canal, it can adapt to the ear canal by comprehensively utilizing the deformation of various dimensions, for example, the buffer space 325 of the ear cap 300 can be partially deformed, but partially undeformed or deformed to a small extent, so that the buffer space 325 can be in a form similar to "inclined", and further the orientation of the sound outlet 323 can be changed. For example, a portion of the wall of the sleeve 321 located at the periphery of the sound outlet 323 is pressed, and the other portion is not pressed or slightly pressed, so that the buffer space 325 can be in an "inclined" state, and the orientation of the sound outlet 323 can be changed. For example, when one side of the sheath 321 is pushed upward in the height direction or one side is pressed downward in the height direction, the two sides of the sheath 321 are unbalanced, and the buffer space 325 can be in an "inclined" state.

Fig. 8 illustrates the ear cap 300 in a configuration before and after entry into the ear canal, as shown in fig. 8. When earcap 300 enters the auditory canal, at first can receive the extrusion of auditory canal, and can produce the compression in side direction and/or direction of height, and the deformation of two kinds of dimensions can make earcap 300 present the change of freedom, and then can adapt to the auditory canal structure better, goes out the position of sound hole 323 and changes with the orientation is complied with the auditory canal structure, better towards in the auditory canal, and the deformation of multidimension degree can make earcap 300 more hug closely the auditory canal moreover, wears more stably, and sealed effect is better.

As previously mentioned, the included angle α may be 0 ° to 180 °. Fig. 5 illustrates an exemplary configuration of an ear cap 300 having an included angle α of less than 90. Fig. 9 illustrates an exemplary configuration of an ear cap 300 having an included angle α greater than 90.

When the included angle α is smaller than 90 °, the connecting position between the connecting portion 322 and the sleeve body 321 is moderate, so as to support the sleeve body 321 more evenly, so that the structure has better balance and stability, and the second wall body 3212 can be effectively limited from turning outward toward the first wall body 3211.

When the included angle α is greater than 90 °, the connection position of the connection portion 322 and the sleeve 321 is closer to the sound outlet 323 than the structure with the included angle α less than 90 °.

In this case, in order to improve the effect of restricting the outward turning of the second wall 3212 toward the first wall 3211, the following structure may be further provided in this embodiment:

the ear cap 300 further includes support ribs 330. The supporting rib 330 is disposed on a side of the second wall 3212 facing the supporting space 326, i.e., a side of the second wall 3212 facing the cap post 310, for supporting and reinforcing the second wall 3212. One end of the supporting rib 330 may abut against the connection portion 322 and the connection portion of the second wall 3212, and the other end of the supporting rib 330 may extend to the edge of the second wall 3212 along the opening 324. Alternatively, the sectional area of the support rib 330 in a plane perpendicular to the axial direction of the cap post 310 is gradually reduced along the extending direction thereof, which can effectively enhance the effect of restricting the eversion of the second wall 3212. Alternatively, the number of the support ribs 330 may be plural, and the plural support ribs 330 are arranged at intervals along the circumferential direction of the case body 321.

In this case, in order to improve the adaptive effect of the buffer space 325, the present embodiment further adopts the following exemplary means:

the soft glue hardness of the connecting part 322 is less than or equal to 40A, and is optionally less than or equal to 30A. That is, the included angle α is greater than 90 °, and the soft rubber hardness of the connection portion 322 may be less than or equal to 40A. Further, the soft rubber hardness of the sleeve body 321 and the connecting part 322 is less than or equal to 40A, and is optionally less than or equal to 30A.

No matter the included angle α is larger than 90 ° or smaller than 90 °, the earcap 300 can possess good and effective ear canal adaptivity characteristics, and can effectively better adapt to various ear canal structures.

Based on the structural description of the above embodiment, the related art shown in fig. 1 is compared with the embodiment to further illustrate the effects of the embodiment:

compared with the common ear cap a shown in fig. 1, in the present embodiment, the connecting portion 322 is disposed to connect the sleeve body 321 and the cap post 310, and the connecting portion 322 is connected between two ends of the sleeve body 321 and forms the buffer space 325, so that the internal supporting structure of the ear cap 300 can be effectively changed, the buffer space 325 is formed at the top to enhance the air buffer area, and the intrusion feeling during wearing can be reduced. Moreover, the supporting structure of the sleeve body 321 by the connecting part 322 improves the sealing support and the angle self-deformation adjustment of the sleeve body 321 in the ear canal, and does not influence the sound transmission direction of the acoustic sound emission channel tube. Acoustic seal passive performance is improved from both the direction of the seal and support adaptation angles, and the buffer space 325 at the top enables the earcap 300 to adapt to different ear canal shapes and sizes, thereby improving wearing comfort.

Specifically, the provision of the buffer space 325 enables to increase the air buffer area at the top, lengthen the buffer elastic area, and effectively adjust the depth of the ear and the wearing stable support position when being worn to the ear canal, and for the ear cap 300, it is mainly the external ear canal support. Compared with the common earcap A, the lengthened air buffer area can compensate the length of different auditory canals which stably support the external auditory canal in the insertion direction (namely the height direction), so that the gap between the top and the external auditory canal in the insertion direction can be compensated under most conditions, the external auditory canal can be better supported, elastic compression can be generated due to the elastic characteristic of the air buffer area, different external auditory canal structures can be better adapted, and meanwhile, the stability and the wearing comfort are both considered.

The provision of the connecting portion 322, in addition to forming the cushioning space 325, can also provide a further unexpected effect to the ear cap 300, of which several are exemplified below:

1. due to the supporting function of the connecting portion 322 on the sleeve body 321, the sleeve body 321 can be stably deformed no matter the ear cap 300 is worn in the ear canal or the ear cap 300 is pulled out from the ear canal, so that the sleeve body 321 is not easy to turn outwards. Especially, when the earphone is pulled out from the ear canal, the negative pressure suction force of the earcap can cause the direct outward turning from the cap sleeve A2 of the common earcap A to the top of the earcap A as shown in fig. 1, the structural stability is poor, and the experience is not good. The supporting position of the connecting portion 322 of this embodiment is between the two ends of the sheath body 312, which will enhance the ability of the sheath body 312 to overcome the negative pressure suction force, and will not deform and turn outward.

2. Due to the supporting function of the connecting portion 322, the sheath 321 and the cap post 310 are supported in the transverse direction, which is different from the longitudinal stretching of the common ear cap A shown in FIG. 1. The rotation angle of the axle center of the sleeve body 321 (the rotation through the connecting part 322) is larger than that of the common earcap A. The rotation axis of the common ear cap a is at the top end, while the rotation axis of the ear cap 300 of the present embodiment is substantially at the middle portion (or around the connection point of the connection portion 322 and the cap post 310), so that the angle for generating the adaptive external auditory canal is much larger than the angle capable of being generated by the common ear cap a, thereby improving the adaptive performance.

3. Due to the arrangement of the connecting portion 322, the earcap 300 with various wearing experiences can be designed according to the thickness d of the connecting portion 322, designability is high, the design space and the function of the earcap 300 can be greatly enriched due to the existence of the connecting portion 300, and the earcap 300 meeting different consumption requirements and different comfort requirements can be designed.

4. The earcap 300 is stronger than ordinary earcap A in the sealed meeting of outer duct, compares in the situation that ordinary earcap A's cap cover does not have the support, and this embodiment sets up connecting portion 322 and supports between the both ends of the cover body 321, can support the suitable position of external auditory canal with the cover body 321 more effectively, and the leakproofness of the cover body 321 can promote, promotes passive noise reduction effect.

All in all, through setting up connecting portion 322 and forming buffer space 325, can make the position and the orientation that draw sound hole 323 can the change of adaptability, so when meetting the canal and turning round, or when the structure of more special canal, draw sound hole 323 can better cooperate the canal to change position and orientation, and earcap 300 can more hug closely the canal moreover, promotes to wear stability and leakproofness, and then promotes and wears the comfort level.

To sum up, above-mentioned embodiment can strengthen the adaptation function of earcap 300, can adapt to more extensive different users 'various different duct structures, because the dimensionality of deformability increases moreover, and its deformation can better support user's duct after wearing, increases and wears stability and leakproofness, promotes the noise reduction effect, also can promote simultaneously and wear the comfort level.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
