When assembled, the shaft portion of the shaft plug 32 is compressively disposed in the eccentric shaft 31, achieving stable assembly between the shaft plug 32 and the eccentric shaft 31, preventing sound from directly propagating outward through the eccentric shaft 31. The second section 2 can be axially limited through the head, so that the second section 2 can only rotate in a preset area, the second section 2 is prevented from moving up and down in the rotation process, and the stability of the movement of the second section 2 is improved.

The eccentric shaft 31 is also sleeved with a sealing ring 33, and the sealing ring 33 is arranged at the joint of the second section 2 and the eccentric shaft 31. In this way, the joint between the second section 2 and the eccentric shaft 31 can be sealed by the seal ring 33, and the occurrence of sound leakage at the joint between the eccentric shaft 31 and the second section 2 can be avoided. The seal ring 33 may be made of a high elastic material such as urethane rubber. The polyurethane rubber has the advantages of high hardness, good strength, high elasticity, high wear resistance, tear resistance, aging resistance, ozone resistance, radiation resistance, good conductivity and the like. Fluororubbers have excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance. The choice of the material of the sealing ring 33 can utilize the excellent properties of the materials, so that the sealing ring meets the sealing performance requirement and has higher service life and higher use reliability.
