Description

Adjustable dulcimer sound stopping device

Technical field

The utility model relates to a kind of sound stop device, relates in particular to a kind of dulcimer sound stopping device.

Background technology

Dulcimer is as a kind of percussion instrument and since its tone color not only as the sound of piano, but also, be widely used in band performance as the sound of musical instruments such as Zheng, Chinese lute, Ruan, liuqin; Simultaneously because the string of dulcimer is many, phoneme is many, resonating body is big, play that effect gives great volume, reverberation length, lingering sound are difficult to control; Other musical instruments end after the sound, have also lingering sound continuation of dulcimer only, in use lack perfection, and the dulcimer user is appealing to have sound stopping device to make it perfect more always.

The big dulcimer sound stopping device of whole press-down type has appearred having at present, its technical scheme that generally adopts is: above the rolling plate of the dulcimer left and right sides plank that is stained with felt is arranged, pass the physical construction of rolling plate and soundboard, step on the plank that pedal has felt and move up and down, the plank that is stained with felt is contacted with string reach only sound purpose.Though this kind structure can reach the only purpose of sound, but still exist following deficiency in its actual use: 1, the positional structure of ending the sound plank is a fixed range, felt and each root string spacing can not be adjusted, sound stopping device usually can not be pushed down all strings simultaneously makes it stop vibrations, and it is relatively poor to end the audio fruit.2, the sound stopping device volume is big, and weight is big, and is portable relatively poor, is not easy to use.

The utility model content

The technical problems to be solved in the utility model provide a kind of simple structure, easy to carry, can adjust the dulcimer sound stopping device that end audio fruit of sound stopping device to every string.

In order to solve the problems of the technologies described above, the utility model provides a kind of adjustable dulcimer sound stopping device, include only soundboard, gear train and the pedal that are arranged on the dulcimer left and right sides, ending soundboard is provided with and the corresponding sound stopping cap of each root string, gear train connects pedal and ends soundboard, described sound stopping cap is fixed on by the bolt adjustable structure and ends on the soundboard, and the top of sound stopping cap is provided with the flexible sound material that ends; Gear train is linkage assembly or pulley blocks.

Adopt the adjustable dulcimer sound stopping device of the technical program to have following advantage: 1, owing to adopted the sound stopping cap that is threaded structure, can adjust the distance between sound stopping cap and every string, be convenient to the vibrations that soundboard is only once cut off all strings, end the audio fruit well; 2, because sound stopping device is relatively simple for structure, so better portable.

Further, in order to improve the only audio fruit of sound stopping device, in order to save cost, the described sound material that ends is chosen as felt simultaneously.

Further, it is as follows to limit jointed gear unit: the described soundboard that ends is arranged on the string below, and the position that dulcimer is corresponding with ending the soundboard two ends is provided with the fixing inverted U-shaped stopper slot that ends soundboard; Described linkage assembly is arranged in the resonant tank of dulcimer, include left Fu Liang, right multiple beam, lever left, right lever, left fulcrum and right fulcrum, two fulcrums are separately positioned on the dulcimer about described, on the multiple beam in the hinged left side of one end of lever left, the other end is connected on the pedal by rope, on the multiple beam in the hinged right side of one end of right lever, the other end is connected on the pedal by rope.

Further, it is as follows to limit the pulley blocks drive mechanism: the described soundboard that ends is arranged on the string top, is fixed on the dulcimer by resetting means; Described pulley blocks comprises left chain wheel, right pulley and two pedal pulleys, and it is separately positioned on left and right two lower position and the pedal top positions of ending soundboard, and two ropes are walked around pulley blocks, connect sound stopping device and pedal respectively.

Further, when ending soundboard and be arranged on the string below, cause that only soundboard comes in contact resonance with the dulcimer soundboard, described ending is provided with the noise control pad bottom the soundboard.

Further, for the ease of the sound stopping device of dismounting connecting rod transmission, described rope is connected on lever and the pedal by hook.

Embodiment

Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:

Embodiment 1

As depicted in figs. 1 and 2, the utility model provides a kind of adjustable dulcimer sound stopping device, include only soundboard 1, gear train and the pedal 3 that are arranged on the dulcimer left and right sides, end soundboard 1 and be arranged on the string below, the position that dulcimer is corresponding with ending the soundboard two ends is provided with the fixing inverted U-shaped stopper slot 4 that ends soundboard, end soundboard 1 bottom and be provided with shockproof felt 2, ending soundboard 1 is provided with and the corresponding sound stopping cap 11 of each root string, sound stopping cap is fixed on by bolt arrangement 13 and ends on the soundboard 1, and the top of sound stopping cap 11 is pasted with felt 12; Linkage assembly is arranged in the resonant tank of dulcimer, include the multiple beam 5 in a left side, right multiple beam, lever left 6, right lever, left fulcrum 7 and right fulcrum, two fulcrums are separately positioned on the dulcimer about described, on the multiple beam 5 in the hinged left side of one end of lever left 6, the other end is connected on the pedal 3 by rope 8, on the multiple beam in the hinged right side of one end of right lever, the other end is connected on the pedal by the rope of band hook.
