Kangen resonance instrument prolonging low pitch

Abstract

The invention relates to a kangen resonance instrument prolonging low pitch, which is designed to solve the problems that the existing national low pitch string instrument is slow in audio vibration, smaller in volume and dull in tone, and a western violin is used as a low pitch part instrument, which is not harmonious with style of national music. The rod is designed as a hollow tube to be served as an additional resonance cavity of a main resonance cavity cylinder, the membrane of the instrument is a sound simulating membrane, and strings are at least six metal strings which are pulled by a bow to be uniformly distributed on the tubular rod and strings of the cylinder, so that a main resonance cavity and the additional resonance cavity can generate three-dimensional resonance. The audio is further filtered through loudspeaking openings on the surface of the main resonance cavity and the additional resonance cavity. The kangen resonance instrument prolonging low pitch has the beneficial effects of fundamentally changing the structure of conventional low pitch Huqin and Gehu which use a single resonance cavity by applying modern instrument acoustic theory based on the characteristics of sound resonance of conventional string instruments, thereby highlighting the main cylindrical resonance cylinder and the tubular resonance cavity rod that generate three-dimensional resonance and further filtering the audio of the instrument through the loudspeaking openings on the surface of the main resonance cavity and the additional resonance cavity, so that the noise is effectively eliminated, the tone quality and the tone volume is guaranteed, and the tone is more balanced and melodious.

Description

Technical field: [0001] The invention relates to a national orchestral instrument, in particular to an orchestral instrument with string resonance and extended bass. It belongs to the field of national musical instruments. Background technique: [0002] With the continuous advancement of the "symphony" process of Chinese national bands, the reform and development of bass stringed instruments in Chinese national bands is an important basic issue in the construction of "symphonic" Chinese national bands. Since the 1950s, Chinese musical instrument manufacturers and national musical instrument performers have successively developed and manufactured the first and second generation bass stringed instruments--"bass erhu" (low hu) and "bass leather hu". This has played a positive role in improving the system of national orchestras in the modern sense. However, due to factors such as slow audio vibration, low volume, and dim timbre, many national orchestras still use Western cellos...

AI Technical Summary

Problems solved by technology

[0005] (2) The timbres of Chinese national musical instruments are either high-pitched or mid-pitched, and there is a big difference, but there is no relatively ideal product for bass instruments.

[0006] (3) In the traditional Chinese national orchestra, due to the traditional popular single-line music texture, there is no functional harmony, and there is no so-called "bass part". Therefore, most of the various instruments play melody, and there is no one An instrument dedicated to bass lead and accompaniment roles
