When the vibration damper 1 is used for playing equipment, the buckling end 13 of the first member 10 can be clamped to the shell component of the playing equipment, compared with a rigid connection mode, the shell component connected by the clamping and the vibration damper 1 have larger activity, so that the transmission of vibration can be further slowed down, the vibration influence of the sound generator 2 on the playing equipment is weakened, and the working stability of the playing equipment is further enhanced.

And, the buckle end 13 includes two sub-portions 134, and two sub-portions 134 have the interval at least partially, when assembling damper 1, two sub-portions 134 of buckle end 13 can take place deformation and press close to each other to reduce damper 1's assembly degree of difficulty, and after buckle end 13 assembly put into place, two sub-portions 134 can resume deformation, thereby the butt is in the inner wall of shell subassembly, and then can strengthen the joint strength between buckle end 13 and the shell subassembly, therefore can strengthen playback devices's structural stability.

While the present application has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the present application, and in particular, the technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
