The inner shell 11 is located in the middle of the inner shell 1. The front ends of the inner shell 11 and the outer shell 1 are connected. The central axes of the inner shell 11 and the outer shell 1 overlap. There is a gap between the inner shell 11 and the outer shell 1 to form a cavity 12. A reinforcing rib 15 is provided at the front end of the cavity 12. In this way, the overall structure of the outer shell 1 and the inner shell 11 is relatively strong.
[0030] The collar 2 is installed at the front end of the inner housing 11. The inner wall of the front end of the inner housing 11 is provided with a plurality of protrusions 16. The protrusions 16 are arranged along the length direction of the inner housing 11. The outer surface of the collar 2 is provided with a plurality of grooves 21. The grooves 21 are arranged along the length direction of the collar 2. The protrusions 16 are embedded in the grooves 21.
[0031] The outer surface of the outer shell 1 is provided with a first anti-slip strip 17, a second anti-slip strip 18 and a third anti-slip strip 19 from front to back. The multiple first anti-slip strips 17, second anti-slip strips 18 and third anti-slip strips 19 are evenly distributed in a circular shape with equal spacing.
[0032] The cross-sectional dimensions of the outer surface of the outer shell 1 gradually increase from front to back. The outer surface of the outer shell 1 is arc-shaped, and the inner surface of the inner shell 11 is cylindrical.
[0033] There are six reinforcing ribs 15, which are evenly distributed in a circular shape at equal intervals at the front end of the wall 12. The upper surface of the reinforcing ribs 15 is set on the inner wall of the outer shell 1, and the lower surface of the reinforcing ribs 15 is set on the outer wall of the inner shell 11.
[0034] Multiple protrusions 16 are evenly distributed in a circular shape at equal intervals on the front end inner wall of the inner shell 11, and multiple grooves 21 are evenly distributed in a circular shape at equal intervals on the surface of the collar 2.
[0035] The number of the first anti-slip strip 17, the second anti-slip strip 18, and the third protective strip 19 are the same, and the first anti-slip strip 17, the second anti-slip strip 18, and the third protective strip 19 are distributed alternately from front to back.
[0036] An annular groove 14 is provided on the inner wall of the rear end of the outer shell 1.
[0037] The outer diameter of the collar 2 is matched with the inner diameter of the central through hole 13.
[0038] The spacing between the second anti-slip strip 18 and the first anti-slip strip 17 and the third anti-slip strip 19 is the same.
[0039] In summary: the inner shell 11 is located inside the outer shell 1, and the front ends of the inner shell 11 and the outer shell 1 are connected to each other to form an integral structure. Furthermore, multiple reinforcing ribs 15 are provided between the inner shell 11 and the outer shell 1, so that the overall structure of the inner shell 11 and the outer shell 1 is relatively strong and not easily deformed or damaged.
[0040] The collar 2 is located at the front end of the central through hole 13 of the inner shell 11. The inner wall of the front end of the central through hole 13 of the inner shell 11 is provided with a plurality of circumferentially distributed protrusions 16. The outer surface of the collar 2 is provided with a plurality of circumferentially distributed grooves 21. The protrusions 16 and the grooves 21 are adapted to each other. The protrusions 16 can just enter the grooves 21, so that the collar 2 is firmly located at the front end of the central through hole 13 of the inner shell 11.
[0041] The cooperation between the protrusion 16 and the groove 21 can eliminate noise in the sound and has a certain noise reduction effect; the surface of the outer shell 1 is an arc shape that gradually increases from front to back, so that the surface of the outer shell can fit the human ear canal and the outer shell 1 can be inserted into the human ear canal relatively easily and comfortably.
[0042] The surface of the outer shell 1 is provided with a first anti-slip strip 17, a second anti-slip strip 18, and a third anti-slip strip 19 from front to back. There are multiple first anti-slip strips 17, second anti-slip strips 18, and third anti-slip strips 19, which are arranged in a circumferential pattern with equal spacing. Moreover, the first anti-slip strips 17, second anti-slip strips 18, and third anti-slip strips 19 are staggered from front to back. In this way, when the outer shell 1 is inserted into the human ear canal, the first anti-slip strips 17, second anti-slip strips 18, and third anti-slip strips 19 can fit snugly inside the ear canal, thereby increasing the friction between the outer shell 1 and the skin inside the human ear canal. Thus, the outer shell 1 will not loosen or shake when worn in the human ear canal.
