The hard cover plate 2 is made of hard plastic, and preferably made of hard material which can generate resonance with the vibration plate of the bone conduction vibrator to form an amplification sound effect. The side edge of the hard cover plate 2 forms a two-stage step surface from the vibration transmission surface 202 to the contact surface 201, so that the orthographic projection area of the vibration transmission surface 202 is larger than that of the contact surface 201, and the vibration transmission surface 202 is abutted with one surface, close to the opening end 102, of the hollow bottom 103. By the assembling mode, adhesives or other additives for assisting fixation are not needed in the assembling process, and the influence of the substances on the vibration transmission effect and the sound quality of the bone conduction vibrator is further avoided. In fact, as shown in fig. 5, the inner side edge of the hollow bottom 103 of the soft kit 1 is also correspondingly set as a step surface, so that the hard cover plate 2 is completely embedded into the hollow part of the hollow bottom 103, and the hard cover plate and the hollow bottom are completely attached without using an adhesive for assisting in fixing and connecting.
Preferably, a clamping piece 223 extends from a side edge of the vibration transmission surface 202 and protrudes from the hard cover plate 2, and when the hard cover plate 2 is embedded into the hollow bottom 103, the clamping piece 223 abuts against the hollow bottom 103 to prevent the hard cover plate 2 from excessively passing through and falling off from the hollow bottom 223.

After the fixing member is stabilized, the housing of the bone conduction vibrator 3 is placed into the accommodating space 101 along the guiding rib 110 (arrow direction in fig. 9) inside the soft sleeve 1, so that the vibration surface 31 of the bone conduction vibrator 1 contacts the vibration surface 202 of the hard cover plate 2, and the electric connection end 32 of the bone conduction vibrator 3 enters the opening end 102 of the soft sleeve 1.
The bone conduction vibrator 3 is fixed in the accommodating space 101 through the soft sleeve 1, specifically, the bone conduction vibrator 3 is convenient to transition due to the fact that the elastic support sheets 113 at the opening end 102 are deformed and bent in the process that the bone conduction vibrator 3 is placed in, after the bone conduction vibrator 3 is completely placed in, the elastic support sheets 113 at the opening end 102 are restored to form a support frame at the opening end 102, the electric connection end 32 of the bone conduction vibrator 3 is supported, and the bone conduction vibrator 3 is prevented from falling from the accommodating space 101 of the fixing piece.
