[0033] See also Figures 1 to 5 , the embodiment of the utility model provides an ear canal seal adaptive rotation structure, including an ear canal seal 2, an ear mouth 3 and a housing 1;

[0034] The housing 1 has a sound-generating end, the ear nozzle 3 is mounted on the sound-generating end, a first rotational matching portion 301 is provided on the outer wall of the ear nozzle 3, the ear canal seal 2 has an ear inlet portion 201 inserted into the ear canal of a human body and a plug-in portion 202 inserted into the ear nozzle 3, the plug-in portion 202 is connected to the ear inlet portion 201, and a second rotational matching portion 203 rotationally matched with the first rotational matching portion 301 is provided on the inner wall of the plug-in portion 202;

[0035] When the inserting portion 202 is inserted into the ear mouth 3 , the second rotation fitting portion 203 is sleeved on the first rotation fitting portion 301 and can rotate relative to the first rotation fitting portion 301 .

[0036] In this embodiment, the outer wall of the ear nozzle 3 is provided with a first rotating fitting portion 301, and the inner wall of the plug-in cloth of the ear canal seal 2 inserted into the ear nozzle 3 is provided with a second rotating fitting portion 203. When the plug-in portion 202 is inserted into the ear nozzle 3, the second rotating fitting portion 203 is sleeved on the first rotating fitting portion 301 and can rotate relative to the first rotating fitting portion 301. Through the above design, when the user wears the ear canal seal 2 into the ear, the ear canal seal 2 and the ear nozzle 3 can also be driven to rotate relative to each other to adjust the best ear insertion position, which is conducive to improving the user's convenience and greatly improving the user's experience.

[0037] Furthermore, the first rotational matching portion 301 and the second rotational matching portion 203 in this embodiment have various structural forms.

[0038] One structural form is: the first rotating fitting portion 301 is an annular arc protrusion protruding outwardly on the outer wall of the ear mouth 3, and the second rotating fitting portion 203 is an annular groove matching with the annular arc protrusion;

[0039] When the plug-in portion 202 is inserted into the ear mouth 3, the annular groove is sleeved on the annular arc protrusion and can rotate relative to the annular arc protrusion.

[0040] Another structural form is: the second rotational matching portion 203 is an annular arc protrusion protruding outwardly on the inner side wall of the plug-in portion 202, and the first rotational matching portion 301 is an annular groove matching with the annular arc protrusion;

[0041] When the plug-in portion 202 is inserted into the ear mouth 3, the annular groove is sleeved on the annular arc protrusion and can rotate relative to the annular arc protrusion.

[0042] It should be noted that, through the rotational cooperation of the above-mentioned annular arc protrusion and the annular groove, the ear canal seal 2 and the ear mouth 3 can be rotated relative to each other. The design of the annular arc protrusion and the annular groove can reduce the resistance during rotation, which is conducive to making the ear canal seal 2 rotate more smoothly and more convenient for users to use.

[0043] Furthermore, the ear tip 3 in this embodiment is made of metal material;

[0044] The plug-in portion 202 is made of hard plastic material.

[0045] It should be noted that by limiting the material of the plug-in portion 202 and the ear mouth 3, the friction resistance between the plug-in portion 202 and the ear mouth 3 can be reduced, so that the ear canal seal 2 can rotate more smoothly.

[0046] Furthermore, the ear inlet 201 in this embodiment is made of soft plastic material.

[0047] It should be noted that, through the above design, the comfort of the user wearing the ear canal seal 2 can be improved.

[0048] Furthermore, the ear inlet 201 in this embodiment has a first side surface and a second side surface, the first side surface and the second side surface are both curved surfaces, and the curvature of the first side surface is different from the curvature of the second side surface.

[0049] It should be noted that in the above design, the curvatures of the first side surface and the second side surface of the ear inlet portion 201 are different. The cooperation between the two can make it easier for the user to insert the ear canal seal 2 into the ear.

[0050] See also Figures 1 to 5 , a sound playing device provided by an embodiment of the utility model comprises a sound generating unit 5 and the above-mentioned ear canal sealing member 2 adaptive rotating structure;

[0051] The sound generating unit 5 is installed in the shell 1 of the adaptive rotating structure of the ear canal seal 2 and is arranged close to the sound generating end of the shell 1 .

[0052] It should be noted that in the sound playback device of this embodiment, the outer wall of the ear mouth 3 is provided with a first rotating fitting portion 301, and the inner wall of the plug-in cloth of the ear canal seal 2 inserted into the ear mouth 3 is provided with a second rotating fitting portion 203. When the plug-in portion 202 is inserted into the ear mouth 3, the second rotating fitting portion 203 is sleeved on the first rotating fitting portion 301 and can rotate relative to the first rotating fitting portion 301. Through the above design, when the user wears the ear canal seal 2 into the ear, the ear canal seal 2 and the ear mouth 3 can also be driven to rotate relative to each other to adjust the best ear insertion position, which is conducive to improving the user's convenience and greatly improving the user's experience.

[0053] Furthermore, the periphery of the sound-emitting unit 5 in this embodiment is covered with a protective cover 4 , and the protective cover 4 abuts against the inner wall of the housing 1 .

[0054] It should be noted that the protective cover 4 in this embodiment is specifically used to protect the sound-emitting unit 5 and provide a buffer when the unit is hit by an external force.

[0055] Specifically, the protective cover 4 in this embodiment is a silicone protective cover 4 or a rubber protective cover 4 .

[0056] Furthermore, the sound-emitting unit 5 in this embodiment is a speaker, and this embodiment does not limit the number thereof. Designers can set multiple or one sound-emitting unit 5 according to needs.
