Description

Technical Field

[0001] The invention relates to the technical field of musical instruments, and in particular to a sound column. Background Art

[0002] As we all know, violins were developed from the 16th to the 18th century. After continuous improvements and the application of new materials, they are now basically perfect. Traditional violins include violins and cellos. The sound post of existing violins is a round wooden section with flat surfaces at both ends that are slightly inclined with the box. It has two functions. One is to tighten the panel and back of the violin to create inward stress. When there is an external force (such as the vibration of the strings), the stress rebounds and causes resonance, making a sound; the second is to transmit the stress of the panel and the external force vibration to the back, causing the panel and the back to resonate. The role of the sound post in the violin box can be said to be crucial. The four strings of the violin apply pressure to the panel through the bridge. If there is no sound post installed between the panel and the back to support the panel, the panel will be deformed due to the force.

[0003] There are three key links in the installation quality of the sound post. First, the installation position of the sound post should be accurate, which can be easily achieved with some modern auxiliary instruments (such as decibel meters, tuners, etc.); second, the material and thickness of the sound post, which can also be easily achieved through material selection and production technology; third, due to the changes in humidity and temperature in the place where the violin is used, and the natural changes in the stress of the board over time, the support strength of the sound post often needs to be adjusted. Even a few fractions of a millimeter will have an important impact on the sound effect. This adjustment is very important for the violin, and the quality of the adjustment is also very critical to the sound quality. This is easy to do in the factory or in the hands of the violin maker, but once it is in the hands of the user, it is a very troublesome thing to adjust the support strength. Users are often not able to solve it by themselves, and generally can only send it back to the manufacturer for adjustment, which is time-consuming and labor-intensive. Sometimes, after the adjustment in the south, it still cannot reach the ideal state in the north due to the temperature difference and humidity, which is inconvenient to use, especially when the sound post falls off, it is even more troublesome and the performance effect is greatly reduced.

[0004] The traditional sound column craftsmanship structure has the following disadvantages: first, after the sound column is debugged, the top and back panels of the piano will deform along the supporting direction after a period of time, which weakens the stress and worsens the resonance effect; second, due to the weakening of stress, the support becomes loose, and the supporting surfaces at both ends have a certain slope. During long-term practice and performance, they gradually shift along the slope, and it is very common for the sound column to become loose and fall off. Summary of the invention
