[0024] The utility model provides a concealable sound-conducting rubber sleeve 100, comprising a rubber sleeve main body 10 and a sound-conducting tube 20; the rubber sleeve main body 10 and the sound-conducting tube 20 are both made of silicone; the rubber sleeve main body 10 also includes a rubber sleeve shell 101, a supporting wall 102 and a positioning ring 103, a middle portion of the rubber sleeve shell 101 is provided with an accommodating groove 1011 that passes through inside and outside, the supporting wall 102 is arranged at the bottom end of the inner wall of the accommodating groove 1011, a side portion of the rubber sleeve shell 101 is provided with a sound-conducting hole 1012 that passes through inside and outside, the positioning ring 103 is arranged on the outside of the rubber sleeve shell 101 and corresponds to the sound-conducting hole 1012; the sound-conducting tube 20 can be telescopically connected to the inside of the positioning ring 103.

[0025] The present invention also provides an earphone 1000, including the above-mentioned concealable sound-conducting rubber sleeve 100, and also including an earphone shell 30 and a sound-emitting element 40; the earphone shell 30 is composed of a front half shell 301 and a rear half shell 302 connected to each other, and the concealable sound-conducting rubber sleeve 100 is installed inside the earphone shell 30, and a sound outlet hole 303 that passes through the inside and outside is opened on the earphone shell 30, and the inner wall of the sound outlet hole 303 abuts against the outer wall of the positioning ring 103, and the sound-emitting element 40 is installed in the accommodating groove 1011 in the middle of the rubber sleeve shell 101.

[0026] The concealable sound guide rubber sleeve 100 is used to be installed in the earphone 1000. The concealable sound guide rubber sleeve 100 is specifically installed inside the earphone shell 30 composed of the front half shell 301 and the back half shell 302 connected together ( Figure 5As shown), the receiving groove 1011 in the middle of the rubber sleeve shell 101 is used to install the sound element 40, and the supporting wall 102 in the receiving groove 1011 is used to support the sound element 40. Since the connection between the front half shell 301 and the rear half shell 302 will form four-sided gaps on the earphone shell 30, in order to avoid sound leakage in the gaps, the four sides of the rubber sleeve shell 101 can abut against the four-sided gaps on the earphone shell 30. Since the rubber sleeve shell 101 is made of silicone, the four-sided gaps on the earphone shell 30 are tightly sealed to isolate the internal space of the earphone shell 30 into a sealed independent cavity, so that the sound emitted by the sound element 40 in the receiving groove 1011 in the middle of the rubber sleeve shell 101 will not leak to the outside of the earphone shell 30 at the four-sided gaps on the earphone shell 30. When the concealed sound-conducting rubber sleeve 100 is installed inside the earphone shell 30 which is composed of the front half shell 301 and the rear half shell 302, the positioning ring 103 of the rubber sleeve body 10 is installed correspondingly in the sound hole 303 of the earphone shell 30, and the inner wall of the sound hole 303 is in contact with the outer wall of the positioning ring 103. Since the positioning ring 103 is made of silicone, it can be pressed against the sound hole 303, thereby avoiding the formation of a gap between the sound hole 303 of the earphone shell 30 and the positioning ring 103, which causes sound leakage. After the positioning ring 103 is installed in the sound outlet hole 303 of the earphone shell 30, when the user uses the earphone 1000, the user can pull out the sound guide tube 20 in the positioning ring 103, so that the sound guide tube 20 is stretched and extended, and the sound outlet end of the sound guide tube 20 is close to the user's ear hole to play sound to the user in a non-in-ear manner. The sound source is the sound element 40 in the accommodating groove 1011 in the middle of the rubber sleeve shell 101, and the sound of the sound element 40 is transmitted through the sound guide hole 1012 of the rubber sleeve shell 101 to the sound guide tube 20 which is retractably connected to the positioning ring 103 for playback. When the user is not using the earphone 1000, the user can manually retract the sound guide tube 20 that is stretched outside the positioning ring 103 so that the sound guide tube 20 is completely retracted into the positioning ring 103. Since the positioning ring 103 is installed in the sound outlet hole 303 of the earphone shell 30, the sound guide tube 20 can be completely stored in the sound outlet hole 303 of the earphone shell 30 when it is retracted, thereby reducing the size of the earphone 1000 and making it convenient to store and carry.In the present invention, the concealable sound-conducting rubber sleeve 100 is installed in the earphone 1000 for use, so that the four sides of the rubber sleeve shell 101 are abutted and sealed with the four-side gaps generated by connecting the front half shell 301 and the rear half shell 302 of the earphone 1000, thereby preventing sound leakage from the four-side gaps on the earphone shell 30; and the positioning ring 103 in the concealable sound-conducting rubber sleeve 100 is abutted and installed in the sound outlet hole 303 of the earphone shell 30 to prevent sound leakage from a gap between the sound outlet 303 and the positioning ring 103, thereby further optimizing the sound and allowing users to have a better user experience when wearing the earphone 1000; and the sound guide tube 20 in the positioning ring 103 can be retracted by the user, so that the user can store the sound guide tube 20 in the positioning ring 103, and then in the sound outlet hole 303 of the earphone shell 30, thereby reducing the size of the earphone 1000 for convenient carrying by the user.

[0027] In some embodiments, the sound guide tube 20 includes a first tube 201, a second tube 202, and a third tube 203. The first tube 201 is retractably connected to the interior of the positioning ring 103, the second tube 202 is retractably connected to the interior of the first tube 201, and the third tube 203 is retractably connected to the interior of the second tube 202. When the sound guide tube 20 is stretched, the first tube 201, the second tube 202, and the third tube 203 are mutually extended, thereby extending the length of the sound guide tube 20. When the sound guide tube 20 is contracted, the first tube 201, the second tube 202, and the third tube 203 are mutually contracted, thereby shortening the length of the sound guide tube 20. The first tube 201, the second tube 202, and the third tube 203 are all made of silicone. Because the wall of the first tube 201 at the connection with the positioning ring 103 is relatively soft, the first tube 201 can be retracted and connected inside the positioning ring 103. Because the wall of the second tube 202 at the connection with the first tube 201 is relatively soft, the second tube 202 can be retracted and connected inside the first tube 201. Because the wall of the third tube 203 at the connection with the second tube 202 is relatively soft, the third tube 203 can be retracted and connected inside the second tube 202. This arrangement allows the sound guide tube 20 to effectively achieve retraction and expansion.

[0028] In some embodiments, the first pipe 201, the second pipe 202, and the third pipe 203 are all configured to be wide and flat. The first pipe 201, the second pipe 202, and the third pipe 203 are all configured to be wide and flat to form the sound guide tube 20. The wide and flat shape is convenient for users to touch and pull.

[0029] In some embodiments, the widths of the first, second, and third conduits 201, 202, and 203 decrease sequentially. This allows the sound generated by the sound-emitting element 40 to be transmitted and concentrated in the third conduit 203, which has the smallest width, for the user to hear.

[0030] In some embodiments, when the sound guide tube 20 is in the stretched state, the sound guide tube 20 forms a bent shape. The bent shape of the sound guide tube 20 in the stretched state allows the sound guide tube 20 to be oriented closer to the user's ear canal, making it easier for the user to hear the sound from the sound guide tube 20 without inserting the ear into the ear.

[0031] In some embodiments, the rubber sleeve housing 101, the supporting wall 102 and the positioning ring 103 are integrally injection molded. Injection molding the rubber sleeve housing 101, the supporting wall 102 and the positioning ring 103 as a whole can enhance firmness and save production process steps.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive.
