Suspended sound transposition chorded instrument

Abstract

The invention relates to a suspended sound transposition chorded instrument which is manufactured by a modern manufacturing process technology. The suspended sound transposition chorded instrument comprises a chorded instrument framework and an independent sound box suspended and supported on the chorded instrument framework; the right end of a chord is coiled on a chord shaft nail through a right chord pillow wheel and a tensioning wheel; the chorded instrument is characterized in that: each chord is provided with a group of toning and transposition mechanism; the transposition mechanism comprises an upper lever, a pull rod, a lower lever, a supporting wheel arranged in the lower lever, and a fixed chord tone sheet and a semitone cam sheet which are matched with the supporting wheel and arranged on a hexagonal transposition spindle; the rotating pivot of the upper lever is the right chord pillow wheel; and the rotating pivot of the lower lever is a movable sliding support. In the suspended sound transposition chorded instrument, the upper lever and the lower lever are linked to the toning and transposition mechanism, a semitone variable can be adjusted under the condition of not changing the fixed chord tone. The suspended sound transposition chorded instrument has the characteristics that: the generation efficiency is high, mega bass having high penetrating capability can bemade, a five-sound twelve-tone transposition function can be realized, and the chorded instrument is convenient and quick, and precise in tone; moreover, in the twelve transposition tones, each chordonly changes semitone, so the elasticity of the chord can be protected fully.

Description

technical field [0001] The invention relates to a traditional national musical instrument, the zither, in particular to a tone-suspended tuned zither. The tuned zither changes the structural stress mode of the zither body, improves the sounding efficiency, and has the kinetic energy of the twelve-tone five-tone system. Background technique [0002] The traditional Chinese zither is a national musical instrument with a history of two thousand years. It has a wide range, deep and beautiful timbre, and a strong oriental cultural charm. With the development of national music and the popularization of folk music symphony, the deficiencies of guzheng are becoming more and more obvious. It is mainly manifested in two aspects. One is the low efficiency of sound production. The guzheng box restricts the vibration of the soundboard and affects the resonance of the speaker, making it impossible to highlight the timbre of the guzheng in an ensemble of various instruments. Second, it is...

Problems solved by technology

It is mainly manifested in two aspects. One is the low efficiency of sound production. The guzheng box restricts the vibration of the soundboard and affects the resonance of the speaker, making it impossible to highlight the timbre of the guzheng in an ensemble of various instruments.

The second is that it is difficult to transfer. The existing transfer methods cannot be used for long-term high-precision and fast transfer.
