Dulcimer treading stop type damper

Abstract

The invention relates to a dulcimer treading stop type damper. A left fixed beam and a right fixed beam are respectively fixedly provided with two longitudinal conduits which are distributed at intervals, a guide pulley is arranged on the conduit wall of a side opening at the lower end of a lower clamping ring of a pressure spring through a shaft, the pressure spring is arranged in each conduit, an upper clamping ring of the pressure spring is fixedly arranged at the upper part of a connecting rod, the upper end of the connecting rod, the lower end of a left sound stop head beam and the lower end of a right sound stop head beam are fixed together to form a whole body, the lower end of the connecting rod is located at the upper end of the guide pulley after sequentially penetrating through each pressure spring in the conduits and a lower clamping ring of each pressure spring and is connected with one end of a steel wire lead rope, the other end of the steel wire lead rope is converged after bypassing the guide pulley and a universal guide wheel fixed on the corresponding fixed beam and is fixed together with a clamping ring after penetrating through a rope tightening tube arranged at the lower end of the universal guide wheel, one end of a pedal stay is connected with the clamping ring, and the other end of the pedal stay is fixed to a pedal. Under the condition that the traditional structure of a dulcimer is not changed, the dulcimer treading stop type damper has flexible and stable sound playing and stopping effects of the dulcimer, can be used for normally stopping a sound, accords with the playing habits by treading the pedal to play the sound and also has the advantages of simple structure, stability in reliability, good concealment, easiness in operation, long service life and low use cost.

Description

Technical field [0001] The invention belongs to a dulcimer stepping stop type damper. Background technique [0002] The body of Yangqin currently on the market or in use is made of wooden materials. The usual structure is to fix two heads on the two ends of the front and back sides with an arc on one side. A thin wood board is arranged on the end surface to form a piano soundboard, and the space at the lower end of the piano surface soundboard forms a resonance box. String columns are fixedly arranged on both sides of the piano surface soundboard, that is, the upper ends of the two piano headboards, strings are drawn between the two string columns, and a tone code is also arranged between each string and the piano surface soundboard. Obviously, after hitting the strings of the traditional structure of the Yangqin, the strings vibrate for a long time, causing the resonance box to resonate and pronounce. After the other instruments in the band cease to sound, the unique Yangqin re...

Problems solved by technology

Obviously, the dulcimer with this traditional structure will vibrate for a long time after the strings are struck, causing the resonance box to resonate and produce sounds. After the other instruments in the band stop, the lingering sound of the unique dulcimer will not dissipate, resulting in a decline in the overall music effect.

This defect of the dulcimer makes it inconvenient to play with other musical instruments, which limits the development of the dulcimer. At present, there is a lack of dampers with a structure similar to that of a piano.

Although there are dulcimer pedal dampers, they all have complex connection structures, poor stability and reliability, and are difficult to popularize and use.
