Abstract

The invention discloses a violin table tone setting and case assembling tone tuning method and a special device. The special device for the violin table tone setting and case assembling tone tuning comprises an audio swept-signal generator, a power amplifier, a magneto striction audio transducer, a measurement microphone, a measurement amplifier, an analog-digital converter, a special frequency spectrum analysis software and a computer. The violin table tone setting and case assembling tone tuning method is directly started with timber vibration sounding angle, utilizes the audio transduction technology and the computer frequency spectrum analysis technology to respectively generate the frequency response curve of a panel, back panel and a case of a standard violin and a new violin, and sets the tone of the new violin to an expected sounding state through the comparison analysis. The method greatly improves the Doctor Huggis violin table tone setting method, and the computer frequency spectrum analysis technology and the audio transduction technology are applied to the violin tone setting and the case assembling tone setting links. Compared with the traditional tone setting method, the method has the advantages of good intuition and easy control of sound quality.

Description

technical field [0001] The invention relates to the fields of musical instrument production and acoustic quality adjustment. Background technique [0002] In the 1950s, Dr. Carleen M. Hatchins, an American physicist, began to study the vibration and vibration mode of the piano board with the method of acoustic excitation. She used laser holographic interferometry to show the interference fringes of violin vibration. It outlines where the vibrating body bends at different frequencies in terms of the phase motion relative to the static state. The most outstanding contribution of Dr. Huggins is that she presented the normal vibration mode of the violin board in a very practical way. She made a set of piano board tuning device, using a variable sine wave and adjustable power The tone generator is connected to the speaker, and the frequency counter is connected to the speaker. The piano board is kept horizontal, and the belly is down, and different parts are placed above the spe...
