[0030] This utility model proposes an earphone that aims to intercept foreign objects by setting dustproof components in both the first and second sound outlets, effectively preventing foreign objects from entering the first and second sound chambers, thereby avoiding damage to the earphone. Furthermore, when a large amount of foreign objects accumulate on the dustproof components, the user can remove the dustproof components for cleaning or replacement. In this way, the earphone's sound quality is stable while also being more hygienic.

[0031] Please see Figures 1 to 7 In one embodiment of this utility model, the earphone 100 includes:

[0032] Housing 1, wherein an installation cavity 11 is formed inside the housing 1;

[0033] A partition 2 is disposed in the mounting cavity 11 to divide the mounting cavity 11 into a first sound cavity 12 and a second sound cavity 13. The partition 2 is provided with a through hole 21 connecting the first sound cavity 12 and the second sound cavity 13. The first sound cavity 12 is provided with a first sound outlet 121. The second sound cavity 13 is provided with a second sound outlet 131 on the side opposite to the first sound cavity 12. The second sound outlet 131 is arranged in the opposite direction to the first sound outlet 121.

[0034] Dustproof component 3, two dustproof components 3 are provided, one dustproof component 3 is detachably installed in the first sound outlet 121, and the other dustproof component 3 is detachably installed in the second sound outlet 131, so as to prevent dust and foreign objects from entering the mounting cavity 11.

[0035] In this embodiment, the earphone 100 includes a housing 1 and a partition 2. A mounting cavity 11 is formed inside the housing 1, and the partition 2 is installed inside the mounting cavity 11 to divide the mounting cavity 11 into a first sound cavity 12 and a second sound cavity 13. At the same time, a through hole 21 is provided on the partition 2 to connect the first sound cavity 12 and the second sound cavity 13. A first sound outlet hole 121 is provided in the first sound cavity 12, and a second sound outlet hole 131 is provided on the side of the second sound cavity 13 opposite to the first sound cavity 12. The first sound outlet hole 121 and the second sound outlet hole 131 are arranged in opposite directions. It should be noted that the earphone 100 of this application is a dual-cavity earphone 100. A sound-producing unit is provided in the first sound cavity 12. The sound emitted by the first sound cavity 12 is transmitted through the first sound outlet hole 121 and also enters the second sound cavity 13 through the through hole 21 for secondary attenuation before being transmitted out through the second sound outlet hole 131. This ensures privacy without affecting the sound quality of the earphone 100, resulting in a good user experience. It should be further noted that the headphones 100 in this application...

[0036] Specifically, the headphones 100 also include a dustproof component 3. There are two dustproof components 3. One dustproof component 3 is detachably installed in the first sound outlet 121, and the other dustproof component 3 is detachably installed in the second sound outlet 131. That is, the dustproof component 3 intercepts foreign objects such as dust or earwax, so as to effectively prevent foreign objects such as dust or earwax from entering the first sound cavity 12 or the second sound cavity 13. While preventing foreign objects from damaging the headphones 100, the dustproof component 3 can also be removed for cleaning or replacement. In this way, the sound quality of the headphones 100 is stable and more hygienic.

[0037] In one implementation, please refer to Figure 1 and Figure 5 The dustproof component 3 includes a mounting base 31 and a first interceptor 32. The mounting base 31 is detachably mounted on the first sound outlet 121 and the second sound outlet 131. The first interceptor 32 is detachably mounted on the side of the mounting base 31 that extends into the first sound outlet 121 and the second sound outlet 131. The first interceptor 32 is used to initially intercept foreign objects, so as to effectively prevent foreign objects from entering the first sound cavity 12 and the second sound cavity 13.

[0038] In this embodiment, the dustproof component 3 includes a mounting base 31 and a first interceptor 32. The mounting base 31 is detachably installed in the first sound outlet 121 or the second sound outlet 131. It should be noted that the mounting base 31 can be detachably installed in the first sound outlet 121 or the second sound outlet 131 by means of clips or screws, etc. Of course, other detachable installation methods are also possible, and this application does not limit them in any way. Furthermore, the first interceptor 32 is detachably installed on the mounting base 31 and is installed on the side of the mounting base 31 that extends into the first sound outlet 121 or the second sound outlet 131. In this way, while ensuring the normal use of the first sound outlet 121 and the second sound outlet 131, it also ensures that the earphone 100 can be worn normally, so as to prevent the mounting base 31 from damaging the ear canal.

[0039] It should be noted that, in order to facilitate the removal of the mounting base 31 from the first sound outlet 121 or the second sound outlet 131, a protrusion 4 is provided on one side wall of the mounting base 31, a groove 5 that mates with the protrusion 4 is provided on the outer periphery of the first sound outlet 121 or the second sound outlet 131, and a pick-up groove 41 is provided on the side of the protrusion 4 facing the first opening 3111. In this way, it is easy to remove the mounting base 31 from the first sound outlet 121 or the second sound outlet 131.

[0040] In one implementation, please refer to Figures 3 to 6 The mounting base 31 forms a receiving groove 311 with a first opening 3111. The first opening 3111 is oriented toward the first sound cavity 12 or the second sound cavity 13. The bottom wall of the receiving groove 311 is provided with a plurality of spaced first through holes 3112. The first interceptor 32 is detachably installed in the receiving groove 311 to ensure that while intercepting foreign objects, sound can also pass smoothly through the first sound outlet hole 121 and the second sound outlet hole 131, and then be transmitted out through the first through hole 3112.

[0041] In this embodiment, to facilitate the smooth transmission of sound, a receiving groove 311 with a first opening 3111 is formed in the mounting base 31, and the first opening 3111 is positioned facing the first sound cavity 12 or the second sound cavity 13. A plurality of spaced first through holes 3112 are provided on the bottom wall of the receiving groove 311. The first interceptor 32 is detachably installed in the receiving groove 311. In this way, while the sound is smoothly transmitted through the first sound outlet 121 and the second sound outlet 131 and then through the first through hole 3112, foreign objects entering the receiving groove 311 through the first through hole 3112 are intercepted by the first interceptor 32, thereby effectively restricting foreign objects from entering the first sound cavity 12 or the second sound cavity 13, thus ensuring the normal use of the earphone 100.

[0042] It should be noted that the first interceptor 32 can be disassembled and installed in the receiving groove 311 by means of clips or the like, so that the first interceptor 32 can be removed for cleaning or replacement. Of course, other detachable connection methods are also possible, and this application does not limit them in any way.

[0043] In one implementation, please refer to Figures 3 to 6 The first interceptor 32 has a first interception cavity 321 with a second opening 3211 recessed on one side opposite to the first opening 3111. The inner peripheral wall of the first interception cavity 321 has a plurality of spaced second through holes 3212.

[0044] In this embodiment, a first intercepting cavity 321 with a second opening 3211 is recessed on the side of the first intercepting member 32 opposite to the first opening 3111. Multiple spaced second through holes 3212 are provided on the inner peripheral wall of the first intercepting cavity 321. Foreign objects entering the receiving groove 311 accumulate on the inner bottom wall of the first intercepting cavity 321. Sound passes smoothly through the first sound outlet 121 and the second sound outlet 131, and then sequentially through the second through holes 3212 and the first through holes 3112. That is, while ensuring sound can be smoothly transmitted to the outside, foreign objects are effectively intercepted within the first intercepting cavity 321. It should be noted that the first intercepting member 32 is a one-piece molded structure, ensuring structural stability and strength.

[0045] In one implementation, please refer to Figure 6 The first interceptor 32 is shaped like a frustum and gradually expands from the end near the first opening 3111 to the end away from the first opening 3111.

[0046] In this embodiment, the first interceptor 32 is truncated cone-shaped, and the first interceptor 32 gradually expands from the end near the first opening 3111 to the end away from the second opening 3211. That is, the inner peripheral wall of the first interception cavity 321 is inclined. Therefore, foreign objects that fall on the inner peripheral wall of the first interception cavity 321 will slide onto the inner bottom wall of the first interception cavity 321 to effectively collect the foreign objects, thereby effectively intercepting the foreign objects in the first interception cavity 321.

[0047] In one implementation, please refer to Figures 3 to 7 The dustproof component 3 further includes a second interceptor 33, which is detachably installed in the receiving groove 311 and is located on the side of the first interceptor 32 facing the first opening 3111. By setting the second interceptor 33, foreign objects passing through the first interceptor 32 are further intercepted in the receiving groove 311, thereby preventing foreign objects from contaminating the first sound cavity 12 and the second sound cavity 13.

[0048] In this embodiment, in order to further intercept foreign objects, the dustproof component 3 includes a second interceptor 33. The second interceptor 33 is detachably installed in the receiving groove 311 and is located on the side of the first interceptor 32 facing the opening. That is, foreign objects that the first interceptor 32 cannot intercept will be intercepted again by the second interceptor 33, so that the foreign objects are effectively kept in the receiving groove 311, thereby preventing foreign objects from contaminating the first sound cavity 12 and the second sound cavity 13.

[0049] In one implementation, please refer to Figure 7 The second interceptor 33 includes a side panel 331 and a bottom plate 332. One side of the bottom plate 332 is detachably installed on one side of the first interceptor 32. The side panel 331 surrounds the other side of the bottom plate 332 to form a second interception cavity 333 with a third opening 3331. The third opening 3331 is oriented towards the first interceptor 32. A gap is formed between the outer peripheral wall of the side panel 331 and the groove side wall of the receiving groove 311. That is, foreign objects from the first interceptor 32 will fall into the second interception cavity 333 to further intercept the foreign objects in the second interception cavity 333.

[0050] In this embodiment, the second interceptor 33 includes a side panel 331 and a bottom plate 332. One side of the bottom plate 332 is detachably installed on one side of the first interceptor 32, and the side panel 331 surrounds the other side of the bottom plate 332 to form a second interception cavity 333 with a third opening 3331. The third opening 3331 faces the first interceptor 32, and a gap is formed between the outer peripheral wall of the side panel 331 and the side wall of the receiving groove 311. In this way, while ensuring the smooth passage of sound, it also ensures that foreign objects falling from the first interceptor 32 can accurately fall into the second interception cavity 333. It should be noted that the outer peripheral wall of the side panel 331 covers the outer periphery of the second through hole 3212 of the outermost ring of the first interceptor 32, so as to ensure that foreign objects falling from the first interceptor 32 can accurately fall into the second interception cavity 333.

[0051] It should be noted that the base plate 332 can be disassembled and installed on the first interceptor 32 by means of clips or other means, so as to facilitate the removal of the second interceptor 33 for cleaning or replacement. Of course, other detachable connection methods are also possible, and this application does not limit them in any way.

[0052] In one implementation, please refer to Figure 7 The base plate 332 is shaped like a frustum and gradually expands from the end closest to the first interceptor 32 toward the end furthest from the first interceptor 32.

[0053] In this embodiment, the base plate 332 is truncated cone-shaped, and the base plate 332 gradually expands from the end near the first interceptor 32 to the end away from the first interceptor 32. That is, the base plate 332 is inclined on the side connected to the side panel 331. Therefore, foreign objects that fall on the base plate 332 will slide into the second interception cavity 333 to effectively collect the foreign objects, thereby effectively intercepting the foreign objects in the second interception cavity 333.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
