Plate membrane string concord resonance type bass string instrument

Abstract

The invention discloses a plate membrane string concord resonance type bass string instrument which comprises a resonance chamber, an instrument rod, a skin membrane, bottom feet, a bridge, a tailpiece, an outlet, a pattern board, a string pillow and an instrument shaft. A board membrane resonance mode is adopted by the resonance chamber, the upper portion of the front face of a cavity is in soundboard vibration and the lower portion of the cavity is in skin membrane vibration through the resonance of the bridge, a sound beam and a column loudspeaker, and a long rectangular slit, namely, a sound-output hole is reversed at the junction of two materials in the middle. The middle of the front face of a cavity is a main vibration area of pronouncing of the cavity. The bridge is driven to vibrate through vibration of four strings, and an upper sound board and a lower skin membrane are driven to vibrate at the same time to achieve the recombination of the double sound effect. The plate membrane string concord resonance type bass string instrument has the advantages that when the sound board and the skin membrane are vibrated in a concord mode through the bridge, the sound beam and the column loudspeaker, similar physical characteristics should be presented; the setting of the four strings and effective string length enables performance techniques to be simple; the vertically-and-horizontally staggered bridge mode and the geometric performance of the bridge improve the sound quality of concord resonance; due to the fact that the board and the membrane are properly utilized to enable the sound-output holes to be formed in the junction of the board and the membrane, the recombination mode of vibrated audio signals of the board and the membrane is defined.

Description

Technical field: [0001] The invention relates to a plate-membrane string harmony resonant bass stringed instrument, which belongs to the field of musical instrument manufacturing. Background technique: [0002] In our country's national bands, cello and double bass have been used as bass stringed instruments. Whether it is in appearance or in the fusion of timbre, it has always been a heart problem for generations of Chinese folk music performers. With the continuous advancement of the "symphony" process of Chinese national bands, reforming and developing the bass stringed instruments of Chinese national bands is an important task in the construction of "symphonic" Chinese national bands. Since the 1950s, Chinese musical instrument makers and national musical instrument players have successively developed and manufactured the first and second generation bass stringed instruments - "Bass Erhu" and "Bass Gehu", etc., and then successively developed La Ruan, Da Pa, etc. But ...

AI Technical Summary

Problems solved by technology

The bass part "controls" the band to a certain extent and maintains a kind of "order" in the band. Modern national orchestral works are becoming more and more complex. Without this "order", it is difficult for the texture of music works to achieve a full and three-dimensional texture. artistic effect
