Method for implementing orchestral resonance instrument with bass extension effect

Abstract

A method for implementing an orchestral resonance instrument with a bass extension effect is designed for solving problems that an existing national bass string instrument is slow in audio vibration, low in volume and dull in tone and a western violin is extremely inharmonious with the style of national music. A stem is designed to be in the shape of a hollow tube and is used as an auxiliary resonance cavity for a barrel which is used as a main resonance cavity, a membrane is a mocking leather membrane, at least six metal strings are uniformly distributed on the tubular stem and the barrel by means of drawing a bow, so that the main resonance cavity and the auxiliary resonance cavity realize a stereoscopic resonance effect, and audio is further filtered by the aid of a loudspeaker opening on the surface of the main resonance cavity and a loudspeaker opening on the surface of the auxiliary resonance cavity. The method for implementing the orchestral resonance instrument with a bass extension effect has the advantages that modern instrumental acoustic theories are applied on the basis of the resonance characteristics of the traditional string instrument, single structures in which a traditional bass Chinese fiddle and a Ke-hu which are used as resonance cavities are fundamentally changed, the stereoscopic resonance effect which is generated by the barrel used as the main circular resonance cavity and the tubular stem used as the auxiliary resonance cavity is highlighted, the audio of the instrument is further filtered by the aid of the loudspeaker opening of the surface of the barrel and the loudspeaker opening on the surface of the hollow stem, noise and murmur are effectively eliminated, and the tone quality, the volume and the tone are more balanced and melodious assuredly.

Description

Technical field: [0001] The invention relates to a method for realizing an orchestral instrument, in particular to a method for realizing an orchestral instrument with orchestra resonance and bass extension. It belongs to the field of national musical instruments. Background technique: [0002] With the continuous advancement of the "symphony" process of the Chinese national orchestra, the bass part plays a very important role as the pillar of the sound in the orchestra and the basis of the basic rhythm. The rich bass part is undoubtedly a strong and powerful embodiment of multi-part music. The sound of the bass part can make the rhythm of the work more firm, prominent and clear, and its strong resonance balances the overall sound effect of the band. 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 m...
