Sound detection device for violin resonance box

Technical Field

The utility model relates to the technical field of violin resonance box sound detection equipment, in particular to a sound detection device for a violin resonance box.

Background

The violin has been shown for over 300 years, and is one of the most important instruments in western music since the 17 th century, and its production is a very delicate art, and the violin has beautiful tone, is close to human voice, has wide range of sound and strong expressive force, and always occupies a remarkable position in the instruments, called as "king back" in the instruments. In the last hundred years, a great deal of research has been conducted on violins. In order to produce violin with good sound effects, scientists have been trying to find a law of producing excellent violin through various scientific methods and experiments. When the violin is played, the strings generate continuous self-excited vibration by virtue of the friction force of the bows to the strings, and energy is continuously input, so that the sound of the violin is a whole musical sound with comprehensive properties instead of a single sound. The scientific principle is as follows: the source of sound is vibration, the friction force between the bowing strings and the strings causes the strings to vibrate, the source is the generation source of the violin, the vibration of the strings is transmitted to the resonance box through the violin code, loop resonance is formed, and accordingly the violin can emit flood sound.
