The damping member (5) has a first surface (51) at least partially adhered to a side wall (111) of the step surface (11). The elastic sheet (3) has a middle arm (31) corresponding to a second surface (52) of the damping member (5) and a first connecting arm (32) and a second connecting arm (33) respectively provided at both ends of the middle arm (31). The second surface (52) corresponds to the first surface (51). The first connecting arm (32) is fixedly connected with the housing, and the second connecting arm (33) is fixedly connected with the mass block (1).
