Description

Column structure

This creation provides a sound column structure, especially a sound column structure that is installed inside the instrument speaker and can effectively solve the problem of bass diffraction, echo and reverberation.

Whether in the Western or Eastern culture, in music-related fields, many instruments have a speaker structure that can help adjust the sound quality and volume of the instrument. Many electronic, percussion or string instruments have similar speaker structures.

Among such a large number of musical instruments, stringed instruments occupy a very important position. Among them, the Western is also famous for its violin-like instruments. Even the modern Oriental music has introduced Western cello as one of the main characters of bass performance. Generally, the stringed instrument structure of the violin is mainly made up of different degrees of wood, and the column is an important role in the sound quality and volume of the stringed instrument.

Usually, in a stringed instrument speaker, a speaker is mainly composed of a top plate, a bottom plate, and a side plate. For a violin-like instrument, there is a change in curvature between the top and bottom plates. The sound column is sealed between the top plate and the back plate.

Regarding the setting position of the sound column, the general violin musical instrument is mainly located in the area below the bridge seat. The bridge is usually made of a special shape of wood chips, which mainly transmit the vibration of the strings to the speakers to make a sound. In the traditional process, the sound column is a wooden cylinder with its The length and shape of the ends are fitted into the speaker and against the top and bottom plates. Since the top plate and the bottom plate usually have a certain curvature, in the process of installing the sound column, it is usually necessary to continuously cut both ends of the sound column to adapt the shape generated by the top plate and the bottom plate in the sound box.

The sound column can effectively improve the stability and sound properties of the stringed instrument. For violins, the installation of the sound column can only be installed through the speaker's only opening, the f-hole. Therefore, it is time-consuming and labor-intensive to cut the sound column in an artificial manner and gradually install it into the speaker of the stringed instrument. Therefore, some people have developed a sound column structure that can be used to introduce a sound column into an f-hole, and then adjust the length of the sound column or its two ends to fit the top plate and the bottom plate curvature of the speaker.

However, this kind of structure has a great influence on the sound compared with the traditional integrally formed column. In addition to making the stringed instrument unable to make the original sound, there are many problems such as bass diffraction, echo and reverberation.

To solve the problems mentioned in the prior art, the present invention provides a sound column structure. In one embodiment, the sound column structure comprises two studs, a column body, a two-ball column, two covers, and at least one adjusting member.

The two ends of the column body are connected to the two studs, and the two ball studs are sequentially disposed on the other end of the two studs relative to the main body of the column, and each of the two ball studs has one The chamber. The two covers are sequentially disposed on the two ball studs, and the at least one adjusting member is disposed on each of the two studs.

In another embodiment of the present invention, the sound column structure comprises a stud, a column body, a ball stud, a second cover and at least one adjusting member. The sound column body is connected to the stud, and the other end of the sound column body is connected to the stud is provided with a spherical joint.

The ball stud is disposed at the other end of the stud relative to the main body of the post, and the ball stud has a ring chamber, and the two caps are sequentially disposed on the ball stud and the ball joint. The at least one adjusting member is disposed on the stud.

The above brief description of this creation aims to provide a basic explanation of several aspects of the creation and technical features of the creation.
