Sound stopping device of dulcimer

The invention relates to a sound stopping device, in particular to the sound stopping device of a dulcimer. The sound stopping device comprises a transmission rod and a sound stopping plate, wherein a base is arranged on the transmission rod; a spring plate is arranged on one side face of the base; the spring plate, from top to bottom, is sequentially provided with a first sound stopping plate and a second sound stopping plate; and the second sound stopping plate is arranged on the top surface of the base. The sound stopping device of the dulcimer has the advantages that: the conventional mode of stopping a sound by fingers is replaced; by arranging the sound stopping device which is simple in structure in the dulcimer, the problem of difficulty in control due to over-long lingering sound of the dulcimer is solved; and effects of half and fully stopping the sound can be achieved by control.
