Further, a disassembly and assembly head is provided at the end of the disassembly and assembly rod inserted into the shell body, and the size of the disassembly and assembly head is larger than the rod diameter of the disassembly and assembly rod. Further, a disassembly opening is formed on the outer side wall of the annular baffle, and the disassembly opening is used for a user's finger to hook the cover.

[0007] In some implementation solutions, the exposed hole is specifically used for one end of the battery to protrude from the housing; the quick-release ear housing further includes a sealing ring. An annular step surrounding the hole axis is formed on the hole wall of the exposed hole. One end of the sealing ring is arranged on the annular step, the other end of the sealing ring is in contact with the top plate, the outer side wall of the sealing ring is in contact with the hole wall of the exposed hole. The sealing ring is used to sleeve one end of the battery protruding from the housing, and the top plate, the annular step, the hole wall of the exposed hole and the battery are all in interference fit with the sealing ring.

[0008] The second aspect of the present application provides a pair of headphones, including a head beam and two quick-release ear housings provided in the first aspect of the present application. The two quick-release ear housings are respectively arranged at both ends of the head beam.

Detailed implementation manners

[0024] In the related art, a head-mounted earphone includes a head beam, and an ear shell is respectively provided at both ends of the head beam. The ear shell usually has a cover for the user to replace the battery inside the ear shell. The cover is generally fixed by screws or buckles. When fixed by screws, the disassembly and assembly of the cover are cumbersome and require tools, and the screw holes are easily damaged after multiple disassembly. Although the buckle fixation does not require tools, it is difficult to disassemble the cover after assembly, and the buckle structure is easily damaged during disassembly. In view of this, a quick-release ear shell and a head-mounted earphone are proposed in the following embodiments of the present application to solve the above-mentioned drawbacks existing in the related art.

[0025] In order to make the purpose, technical solutions and advantages of the present application more obvious and understandable, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. It should be understood that the various embodiments of the present application described below are only used to explain the present application and are not used to limit the present application. That is, based on the various embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to Figures 1 to 5 , Figure 1 which shows a structural schematic diagram of the quick-release ear shell, Figure 2 which shows an exploded schematic diagram of the quick-release ear shell, Figure 3 which shows a structural schematic diagram of the shell cover, Figure 4 which shows a cross-sectional view of the quick-release ear shell, Figure 5 which shows Figure 4The partial enlarged view of the B in the middle. This embodiment provides a quick-detachable ear shell, which is applied to headphones. The quick-detachable ear shell includes a shell cover 1 and a hollow shell 2. The shell 2 is used to install a battery, and the battery is used to provide power during the operation of the headphone. The shell 2 is provided with an exposure hole 21 and a plurality of disassembly holes 22 connected to the inside of the shell 2. The exposure hole 21 and the plurality of disassembly holes 22 are located on the same side of the shell 2. The exposure hole 21 is used to expose the battery for subsequent battery replacement. The disassembly hole 22 is provided with an elastic ring 3, and the outer side wall of the elastic ring 3 is in contact with the hole wall of the disassembly hole 22. The shell cover 1 is provided with a plurality of disassembly rods 4 corresponding to the plurality of disassembly holes 22 / elastic rings 3 on the shell 2, respectively. The shell cover 1 is covered on the shell 2 to cover the exposure hole 21 and the plurality of disassembly holes 22 / elastic rings 3. The plurality of disassembly rods 4 are respectively inserted into the shell 2 through the elastic rings 3 in the plurality of disassembly holes 22, and each disassembly rod 4 is interference-fitted with the corresponding elastic ring 3. It should be noted that the interference between the disassembly rod 4 and the elastic ring 3 can be designed according to actual needs, and this embodiment does not make a sole limitation on this; illustratively, the interference between the two is 0.2-0.3 mm. It should also be noted that the elastic ring 3 can be made of any material with good elastic properties commonly used in the art (the same applies to other elastic components hereinafter), such as rubber, silicone, thermoplastic elastomer (TPE), etc., which can be selected according to actual needs, and this embodiment does not make a sole limitation on this.

[0027] In this embodiment, since an elastic ring 3 is provided in one disassembly hole 22, and one disassembly rod 4 is inserted in one elastic ring 3, the multiple disassembly holes 22, the multiple elastic rings 3, and the multiple disassembly rods 4 correspond to each other in position, and the number of the three is also equal. However, the specific number of the three and the relative positions of the multiple disassembly holes 22 and the exposure holes 21 on the shell 2 can be designed according to actual needs, and this embodiment does not make a sole limitation on this. For example, the number of disassembly holes 22, elastic rings 3, and disassembly rods 4 are all four, the exposure hole 21 is located in the middle of one side of the shell 2, the four disassembly holes 22 are respectively adjacent to the four corners of the exposure hole 21, the four elastic rings 3 are respectively provided in the four disassembly holes 22, and the four disassembly rods 4 are all provided on the shell cover 1 and the positions on the shell cover 1 are adapted to the four disassembly holes 22.

[0028] In this embodiment, the shell 2 is not limited to installing batteries, but can also be used to install other components required for the operation of the headset, such as a motherboard, a driver, a microphone, a wireless module, etc. This is a relatively mature technology in the field, so this embodiment will not be described in detail.

[0029] In this embodiment, the battery inside the housing 2 is replaceable. When the battery inside the housing 2 needs to be replaced, the user can open the housing cover 1 and replace the battery inside the housing 2 through the exposure hole 21. After the battery inside the housing 2 is replaced, the housing cover 1 can be re-covered on the housing 2. That is to say, in actual applications, the user can apply opposite forces to the housing 2 and the housing cover 1 respectively, so that the plurality of disassembly and assembly rods 4 are respectively pulled out from the plurality of elastic rings 3, thereby separating the housing cover 1 from the housing 2, so as to replace the battery inside the housing 2 through the exposure hole 21. After that, when the battery inside the housing 2 is replaced, the user can align the plurality of disassembly and assembly rods 4 on the housing cover 1 with the plurality of disassembly and assembly holes 22 on the housing 2 respectively, and then apply opposite forces to the housing 2 and the housing cover 1 respectively, so that the plurality of disassembly and assembly rods 4 are respectively inserted into the housing 2 through the elastic rings 3 in the plurality of disassembly and assembly holes 22. In this way, the assembly of the housing cover 1 and the housing 2 can be realized. At the same time, since each disassembly and assembly rod 4 is in interference fit with the corresponding elastic ring 3, the housing cover 1 and the housing 2 are not easily separated when no external force is applied to the housing cover 1 and the housing 2. It can be understood that when the disassembly and assembly rod 4 is pulled out from the elastic ring 3, the elastic ring 3 will be deformed by the extrusion of the disassembly and assembly rod 4, and the amount of deformation can be designed according to actual needs. This embodiment does not make a unique limitation on this; for example, when the disassembly and assembly rod 4 is pulled out from the elastic ring 3, the amount of deformation of the elastic ring 3 is 0.3 - 0.6 mm.

[0030] As can be seen from the above, compared with the traditional method of fixing the housing cover 1 with screws or buckles, the disassembly and assembly of the housing cover 1 in this embodiment is simpler, without the need to use any tools, nor to set multiple screws or multiple buckles, which can reduce the manufacturing cost of the ear shell. At the same time, it will not be as easy as the traditional method to damage structures such as screw holes and buckles, which can extend the service life of the ear shell and the user experience is also better.

[0031] In some embodiments, please refer to Figures 1 to 5 , and in combination with Figures 6 to 8 , Figure 6 is Figure 2 a partial enlarged view of part A in Figure 7 a schematic structural diagram of the elastic ring from a perspective, Figure 8: is a schematic diagram of the structure of the elastic ring under another perspective. An annular plug plate 6 is formed on the hole wall of the disassembly hole 22, which surrounds the hole axis of the disassembly hole 22. An annular slot 31 is provided on the outer wall of the elastic ring 3, which surrounds the central axis of the elastic ring 3. When the elastic ring 3 is arranged in the disassembly hole 22, the annular plug plate 6 is inserted in the annular slot 31, which can improve the stability of the elastic ring 3 in the disassembly hole 22 and reduce the risk of it being separated from the disassembly hole 22. It can be understood that since the annular slot 31 surrounding the central axis of the elastic ring 3 is provided on the outer wall of the elastic ring 3, the elastic ring 3 is an I-shaped, which includes large-sized parts located at both ends and a small-sized part connected between the two large-sized parts, and the thickness of the large-sized part and the small-sized part can be designed according to actual needs, and this application does not make a sole limitation on this; for example, the thickness of the large-sized part is 1.2~1.6mm, and the thickness of the small-sized part is 0.3~0.8mm.

[0032] As at least one embodiment, a sealing material layer (such as a sealing adhesive layer) is formed between the outer wall of the elastic ring 3 and the hole wall of the disassembly hole 22, so that the stability of the elastic ring 3 in the disassembly hole 22 can be further improved. It should be noted that the fixing method of the elastic ring 3 in the disassembly hole 22 is not limited to glue dispensing. In other embodiments, two-color injection molding, beer sleeve and other solutions can also be used to fix the elastic ring 3. The specific selection can be based on actual needs, and this application does not make a sole limitation on this.

[0033] As at least one embodiment thereof, an elastic plate 7 for blocking the elastic ring 3 is provided on the inner side of the elastic ring 3, and a cross-shaped cutout 71 is provided on the elastic plate 7, and the cross-shaped cutout 71 divides the elastic plate 7 into four sub-elastic plates 72. It can be understood that the purpose of providing the cross-shaped cutout 71 on the elastic plate 7 is to facilitate the insertion of the disassembly rod 4 into the housing 2 through the elastic ring 3, and when the disassembly rod 4 is inserted into the housing 2 through the elastic ring 3, the four sub-elastic plates 72 will bend into the housing 2 and produce compression and deformation with the disassembly rod 4, so that the stability of the insertion of the disassembly rod 4 and the elastic ring 3 can be improved, and the risk of the disassembly rod 4 detaching from the elastic ring 3 can be reduced. It should be noted that the size of the cross-shaped cutout 71 can be designed according to actual needs, and this application does not make a sole limitation on this; illustratively, the size of the cross-shaped cutout 71 is 0.05~0.1mm. It should also be noted that the elastic plate 7 is not limited to the cross-shaped cutout 71. In other embodiments, the elastic plate 7 may also be provided with a straight cutout (dividing the elastic plate 7 into two sub-elastic plates 72), a cross-shaped cutout (dividing the elastic plate 7 into eight sub-elastic plates 72), etc. The specific design can be based on actual needs, and this application does not make a sole limitation on this. It should also be noted that in order to further improve the stability of the plug-in connection between the disassembly rod 4 and the elastic ring 3, a disassembly head 5 can be provided at one end of the disassembly rod 4 inserted into the housing 2, and the size of the disassembly head 5 is larger than the rod diameter of the disassembly rod 4.

[0034] In some embodiments, refer to Figures 1 to 8 , and in combination with Figure 9 , Figure 9 Shown is another cross-sectional view of the quick-release ear shell. The shell cover 1 includes a top plate 11 and an annular baffle 12. The annular baffle 12 is disposed at the edge of one side of the top plate 11. One ends of a plurality of disassembly and assembly rods 4 are all disposed on the side of the top plate 11 adjacent to the annular baffle 12. When the shell cover 1 is covered on the shell body 2, the annular baffle 12 abuts against the shell body 2. In this case, the annular baffle 12 and the top plate 11 together shield the exposed hole 21 and a plurality of disassembly and assembly holes 22 / elastic rings 3. It should be noted that a disassembly opening 121 for a user's finger to hook can be formed on the outer side wall of the annular baffle 12. When it is necessary to disassemble the shell cover 1, the user can first insert a finger into the disassembly opening 121 on the shell cover 1, and then apply force to pry open the shell cover 1 to separate it from the shell body 2.

[0035] As at least one of the embodiments, in addition to the structures listed above, the quick-release ear shell further includes a sealing ring 8. An annular step 9 surrounding the hole axis of the exposed hole 21 is formed on the hole wall of the exposed hole 21. One end of the sealing ring 8 is disposed on the annular step 9, the other end of the sealing ring 8 is attached to the top plate 11 of the shell cover 1, the outer side wall of the sealing ring 8 is attached to the hole wall of the exposed hole 21. One end of the battery in the shell body 2 extends out of the shell body 2 through the exposed hole 21. The sealing ring 8 can be sleeved on the end of the battery extending out of the shell body 2, and the top plate 11, the annular step 9, the hole wall of the exposed hole 21 and the battery are all in interference fit with the sealing ring 8, that is, the sealing ring 8 is squeezed between these components / structures. In this way, the battery can be well fixed through the sealing ring 8, and at the same time, better sealing and waterproof effects can be achieved.

[0036] Please refer to Figure 10 , Figure 10 Shown is a schematic structural diagram of a head-mounted earphone. This embodiment provides a head-mounted earphone, which includes a head beam 10 and two of the quick-release ear shells described above. The head beam 10 is arc-shaped, and the two quick-release ear shells are symmetrically disposed at both ends of the head beam 10. In this embodiment, the head beam 10 includes a main arc beam 101 and two sub-arc beams 102. The two sub-arc beams 102 are symmetrically disposed at both ends of the main arc beam 101. The arc mouth directions of the sub-arc beams 102 are the same as that of the main arc beam 101. The two quick-release ear shells are respectively disposed on the two sub-arc beams 102. Both ends of the sub-arc beam 102 are respectively disposed on opposite sides of the shell body 2 of the corresponding quick-release ear shell. It should be noted that regarding the structure of the head beam 10, the connection manner between the head beam 10 and the ear shell, and the working principle of the head-mounted earphone, etc., they are all relatively mature technologies in this field, so this embodiment does not describe them in too much detail.

[0037] The above embodiments are only the preferred implementations of the present application, and they are not the only limitations on the quick-release ear shell and the head-mounted earphone; in this regard, those skilled in the art can flexibly set according to the actual application scenario on the basis of the above embodiments. It can be understood that through the implementation of the above embodiments of the present application, the quick-release ear shell is formed by the housing 2 and the shell cover 1. The housing 2 is used to install the battery. An exposure hole 21 and a plurality of disassembly and assembly holes 22 communicating with the inside are provided on the housing 2. The exposure hole 21 is used to expose the battery. An elastic ring 3 is arranged in the disassembly and assembly hole 22. The outer side wall of the elastic ring 3 is attached to the hole wall of the disassembly and assembly hole 22. A plurality of disassembly and assembly rods 4 are provided on the shell cover 1. The shell cover 1 is covered on the housing 2 to shield the exposure hole 21. The plurality of disassembly and assembly rods 4 are respectively inserted into the housing 2 through the plurality of elastic rings 3. Each disassembly and assembly rod 4 is in interference fit with the corresponding elastic ring 3. In actual application, the user can apply opposite forces to the housing 2 and the shell cover 1 respectively, so that the plurality of disassembly and assembly rods 4 are respectively pulled out from the plurality of elastic rings 3, so as to separate the shell cover 1 from the housing 2, so as to replace the battery in the housing 2 through the exposure hole 21; after the battery in the housing 2 is replaced, the user can align the plurality of disassembly and assembly rods 4 on the shell cover 1 with the plurality of disassembly and assembly holes 22 on the housing 2 respectively, and then apply opposite forces to the housing 2 and the shell cover 1 respectively, so that the plurality of disassembly and assembly rods 4 are respectively inserted into the housing 2 through the elastic rings 3 in the plurality of disassembly and assembly holes 22. In this way, the assembly of the shell cover 1 and the housing 2 can be realized. At the same time, since each disassembly and assembly rod 4 is in interference fit with the corresponding elastic ring 3, the shell cover 1 and the housing 2 are not easily separated when the shell cover 1 and the housing 2 are not subjected to external forces. It can be seen that compared with the screw or buckle fixation of the shell cover 1 in the traditional scheme, the disassembly and assembly of the shell cover 1 in the present application are simpler, and no tools are required, and it is not easy to damage structures such as screw holes and buckles like the traditional scheme, which can extend the service life of the ear shell, the cost is lower, and the user experience is better.
