[0033] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc. are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0034] Refer to Figures 1-7 , which is an embodiment of the in-ear headphone of the present invention. Refer to Figure 1 and Figure 2 , the in-ear headphone includes a headphone housing 100, a speaker unit 200, a sound outlet net 300 and an ear tip 400. The headphone housing 100 has a cavity and an earplug end 110 protruding forward. The earplug end 110 is provided with a sound outlet channel, and the speaker unit 200 is disposed in the sound outlet channel. In this embodiment, the earplug end 110 is preferably cylindrical. Refer to Figure 7, the sound outlet net 300 includes a metal net 310 and an acoustic mesh cloth 330 fixedly attached to the inner side of the metal net 310 through a double-sided adhesive 320. The metal net 310 plays a supporting role, and the acoustic mesh cloth 330 plays a role in waterproofing, dustproofing, and acoustic tuning. As Figure 3 shown, the ear tip 400 includes a barrel part 410 and a head part 420 located at the front end of the barrel part 410 and inserted into the ear. A magnetic component 500 is arranged inside the barrel part 410, and the sound outlet net 300 is fixed inside the barrel part 410 through the magnetic attraction between the metal net 310 and the magnetic component 500. The barrel part 410 is detachably sleeved on the front end part of the earplug end 110, and the sound outlet net 300 is pressed on the sound outlet at the front end of the sound outlet channel.

[0035] For the above in-ear headphones, the sound outlet net 300 is magnetically fixed on the ear tip 400 to achieve pre-assembled adsorption of the sound outlet net 300, avoiding the use of double-sided adhesive 320, foam adhesive, or glue for pasting, and circumventing the disadvantage of difficult cleaning of residual glue; the sound outlet net 300 can be removed by removing the ear tip 400, enabling convenient replacement of the sound outlet net 300, with convenient and fast operation and easy replacement, achieving the purpose of convenient cleaning of impurities. At the same time, the sound quality of the headphones can be adjusted by replacing different sound outlet nets 300, meeting the needs of different customers.

[0036] Furthermore, the head part 420 of the ear tip 400 is made of soft glue to improve the comfort of the ear tip 400; the barrel part 410 is made of hard glue and is used to connect with the earplug end 110 of the headphone shell 100. The soft glue head part 420 and the hard glue barrel part 410 are formed by double-shot injection molding. The hard glue barrel part 410 belongs to the first shot, and the soft glue head part 420 belongs to the second shot.

[0037] Specifically, as Figure 3 shown, an annular boss part 411 is arranged on the inner wall of the barrel part 410, and a magnetic component 500 is arranged on the boss part 411. As Figure 2 shown, the sound outlet net 300 is supported on the rear side of the boss part 411 and is fixedly adsorbed to the magnetic component 500 through magnetic force. Preferably, while injecting the soft glue head part 420 and the hard glue barrel part 410, the magnetic component and the barrel part 410 are formed by insert injection molding. In other embodiments, an insert groove can be arranged on the barrel part 410, and the magnetic component 500 is fixedly embedded in the insert groove.

[0038] In order to achieve the sealing of the sound channel, it is necessary to seal between the barrel part 410 of the ear tip 400 and the earplug end 110 of the headphone shell 100. In this embodiment, as Figure 5 and Figure 6As shown, a glue seepage port 414 is formed on the boss portion 411, and an annular groove 412 communicating with the glue seepage port 414 is formed on the rear side surface of the boss portion 411; when the head portion 420 and the barrel portion 410 are injection molded by double-shot molding, the head portion 420 forms a sealing ring portion 422 in the annular groove 412 through the glue seepage port 414, as Figure 4 shown. Refer to Figure 2 . The sealing ring portion 422 surrounds the outside of the sound outlet net 300, and the sealing ring portion 422 is in sealing contact with the front end surface of the barrel portion 410. After the earplug 400 is fixed to the earphone housing 100, the soft sealing ring portion 422 provided between the barrel portion 410 and the earplug end 110 is squeezed, realizing the sealing of the sound channel. By using the split glue seepage of the soft glue of the head portion 420 to form the sealing ring portion 422 when the earplug 400, the barrel portion 410 and the head portion 420 are injection molded by double-shot molding, the sealing of the sound channel is realized, and the structure is simple and easy to implement. In this embodiment, as Figure 4 shown, preferably, four long strip-shaped arc-shaped glue seepage ports 414 are arranged circumferentially and evenly, and four connecting bridge portions 421 connected to the sealing ring portion 422 are formed through the glue seepage ports 414 to ensure the connection firmness between the sealing ring portion 422.

[0039] In this embodiment, the magnetic component 500 is preferably an annular magnet, and the annular magnet is embedded in the side wall of the annular groove 412 close to the center of the barrel portion 410. That is, when the head portion 420 and the barrel portion 410 are injection molded, the magnetic component and the barrel portion 410 are fixed between the sealing ring portion 422 and the side wall of the annular groove 412 through insert injection molding. The annular magnet is embedded inside the earplug 400, which can further prevent the annular magnet from falling off.

[0040] In this embodiment, as Figure 2 shown, on the inner ring side of the front end surface of the earplug end 110, there is a stepped portion 111 recessed backward, the sound outlet net 300 abuts on the stepped portion 111, and the sealing ring portion 422 abuts on the end surface outside the stepped portion 111. The depth of the stepped portion 111 is approximately the same as the thickness of the sound outlet net 300. Since the sound outlet net 300 has a certain thickness, setting the stepped portion 111 to receive the sound outlet net 300 can play a positioning role.

[0041] The detachable structure between the earplug 400 and the earphone housing 100 is shown in the figure. The rear end of the barrel portion 410 and the front end of the earplug end 110 are fixed by a snap structure. Specifically, refer to Figure 2 and Figure 3, the snap structure includes an annular protrusion 112 provided on the outer wall of the earplug end 110 and an annular groove 413 provided on the inner wall of the barrel portion 410, and the annular protrusion 112 is snap-fitted and fixed with the annular groove 413. In another embodiment, the positions of the annular protrusion 112 and the annular groove 413 can be interchanged, that is, an annular groove 413 is provided on the outer wall of the earplug end 110 and an annular protrusion 112 is provided on the inner wall of the barrel portion 410.

[0042] In this embodiment, the head 420 of the earcup includes an arc-shaped cover body portion 423 and an inner cylinder portion 424 connected to the center of the cover body portion 423. The inner cylinder portion 424 is sleeved in the barrel portion 410 and abuts against the boss portion 411. In another embodiment, the cover body portion 423 of the head 420 is not limited to the arc-shaped shell shape shown in the figure.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
