[0038] S2, assembly process, after the vibration head 12, the element mechanism 11, the tightening line 13, the first button key 14 and the second button key 15 are assembled, a through groove 3 is opened on the surface of the vibration head 12, and the second sleeve 29 and the threaded tube 212 are respectively fixed and sleeved on the inner wall of the inner cavity of the vibration head 12 to form a symmetrical structure, and then a rolling piece 24 is installed on the surface of the threaded tube 212, and the surface of the rolling piece 24 passes through the inner cavity of the through groove 3 and extends out of the inner cavity of the through groove 3, and then the second sleeve 2 The second sliding rod 28 is slidably sleeved in the inner cavity of the threaded tube 212, and the bolt rod 211 is sleeved in the inner cavity of the threaded tube 212 by threaded rotation, and the fixing ring 210 and the bearing 213 are fixedly sleeved on the surfaces of the second sleeve 29 and the threaded tube 212, respectively, and the arc connecting rod 25 is welded to the bottom of the fixing ring 210 and the bearing 213, and the arc connecting rod 25 is also located in the inner cavity of the vibration head 12, and then the first sliding rod 263 is completely sleeved in the inner cavity of the mounting hole 23 to ensure that the bottom of the first sliding rod 263 The first spring 264 is installed in the inner cavity of the first sliding rod 263, and one end of the first spring 264 is welded with the first sleeve 262, and the first sleeve 262 is slidably sleeved in the inner cavity of the first sliding rod 263, and one end of the first sleeve 262 is extended from the inner cavity of the mounting hole 23, and a rubber ring 261 is connected to the extended surface, and there is a gap between the rubber ring 261 and the surface of the sliding ring 21, and the sliding ring 21 is fixed with the first spring 264. One end of the ring 21 is connected to the limiting ring 22 and welded to one end of the second sliding rod 28 and the bolt rod 211, and then a plurality of second springs 214 are symmetrically connected in a circle at the port of the sliding ring 21, and one end of each second spring 214 is connected to a rubber sleeve 27, and both ends of the rubber sleeve 27 will be wrapped on the surface of the port of the sliding ring 21, and finally the vibrator of the vibration head 12 is installed in the inner cavity of the rubber sleeve 27, and the sliding ring 21 and the rubber ring 261 are squeezed and slidably sleeved at the port of the vibration head 12.

[0039] When in use, first place the vibration head 12 on the skull next to the ear, and automatically tighten it through the tightening line 13 to make it fit on the neck, then rotate the rolling plate 24, so that the rotation of the rolling plate 24 drives the threaded tube 212 and the bolt rod 211 to rotate in reverse and move in the opposite direction.

In this way, the tilting of both sides will be against the change of the port, so that there will be no gap between the connection between the port of the vibration head 12 and the sliding ring 21, thereby preventing rainwater from entering.

[0040] Furthermore, the vibrator in the inner cavity of the vibration head 12 will be covered with a cover plate on the surface, which is connected to the inner cavity of the rubber sleeve 27 so that it is hidden in the inner cavity of the sliding ring 21. Its lead wires will also be in the inner cavity of the sliding ring 21 so that its electrical components will not be exposed. The vibrator generates vibrations through sound waves, and then transmits the sound through the bones, and one end of the rubber ring 261 is fixedly connected to the surface of the rubber sleeve 27.
