Full-frequency response theory and technology application in violin manufacturing

Abstract

The invention is suitable for the technical field of music appliances, and provides a full-frequency response theory and technical application in violin manufacturing, and the full-frequency response theory comprises a soundboard which comprises a panel and a backboard, and a sound post is arranged between the panel and the backboard; the bass beam is used for supporting the panel and dividing a bass vibration area; the bridge is arranged on the soundboard, and the bridge is used for supporting the strings and transmitting vibration of the strings; the step of adjusting the thickness distribution of the soundboard specifically comprises the following steps: setting a vibration center of the soundboard, determining the thickness of the center, and performing radial thinning distribution towards the periphery of the soundboard according to a certain slope from the center. The pronunciation of the violin is more balanced and loud, and the tone quality is greatly improved; a good musical instrument can be made by adopting a method of changing the center thickness of the soundboard according to the difference of materials; the regularity of soundboard processing thickness data is high, mechanical production is facilitated, material selection difficulty is reduced, meanwhile, material and processing cost is reduced, and high-quality violin can be produced.

Description

technical field [0001] The invention belongs to the technical field of musical instruments, and in particular relates to full-frequency response theory and technical application in violin making. Background technique [0002] At present, the soundboard of the violin is made with the frequency of the percussion sound as the standard. Due to the difference in the density of the soundboard material, it is difficult to make the percussion sound meet the set percussion sound frequency requirements. Therefore, it is difficult to select materials. For example, a soundboard of the same thickness will have a difference of several tens of hertz in its natural frequency. Another method is Dr. Carrion Hutchinson's soundboard tuning method, which is to set the natural frequency of the soundboard to tune the sound. The results are consistent with the previous method. The essence of the above two methods is based on determining the natural frequency of the soundboard. [0003] In the p...

Problems solved by technology

The biggest problem is that the frequency range of the violin's pronunciation is very wide. According to the resonance theory, the vibration frequency far away from the natural frequency of the soundboard will be weakened, and the vibration frequency close to it will be strengthened. As a result, the violin's pronunciation will be unbalanced.
