The acoustic characteristics of the violin are part of the field of instrument acoustics in the field of musical acoustics, and the four elements of sound (timbre, pitch, pitch, pitch and intensity) are the theoretical basis. According to the development of the structural characteristics of the violin, the acoustic system of the violin is mainly composed of strings, bows, codes and resonance boxes.
Among them, the source of the violin sound is the string, the bow, the transmission sound is completed by the piano code, and the resonance box is the sensing system of the violin. The timbre of the violin is influenced by a variety of factors. Therefore, to improve the acoustic quality of the violin, it is necessary to start from many aspects.
Choose the right code
If you find that the violin sound is not smooth, you can consider replacing it with a thin piano code, and the material should choose softer, smaller wood. If the violin sound is noisy, it should be replaced with a wooden code with a harder material and a larger volume. When replacing, pay attention to the appropriate range.
Choose a string with the right thickness
When the strings are of the same material and play the treble, the thick strings require more tension, which is not prone to bending, and the sound of playing is greater; if it is a thin string, the sound will be brighter. Therefore, if the violin is noisier, the thicker strings can be selected, and if the sound is low, the thinner strings can be selected. For example, the C11 violin strings of Qingge are relatively thin strings.

Well-designed panels
The shape of the violin panel affects the timbre, clarity and strength of the violin, and how to improve the influence of the panel on the violin mainly starts from the thickness of the panel. The panels are mainly designed according to the shape of the violin, the degree of softness and hardness of the wood, and the height of the surface arc.
The role of the violin back plate is mainly to reflect the vibration generated by the panel, therefore, the curvature of the violin's back plate should not be too high, it is best to make a thicker form in the middle and thinner on both sides, and the arc is a pointed circle form.
Adjust the appropriate column position
The sound column plays a decisive role in the sound of the violin. The resonant frequency of the sound column itself will generally be higher than the resonant frequency required by the violin, so there is no need to tune the sound column, but adjust its position to a reasonable state and do not easily change its position. Slightly moving the position of the pitch will change the timbre of the violin. The position of the general sound column should be located 1.5 mm to 3 mm behind the right horse foot, in the same straight line as the violin bass beam on the symmetry of the midline of the panel.
