Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tone color adjusting apparatus for a stringed instrument, and more particularly, to a tone color adjusting apparatus for a stringed instrument, which adjusts a tone color by adjusting a gap between a front plate and a back plate.
In general, a stringed instrument is a collective term for musical instruments that make a sound by vibrating using strings. The strings are usually made of sheep's intestines or metal, and vary in pressure depending on the type of sound desired and the size required. And make a sound by turning on or off the bow. The stringed instruments that are often played in the West are the violin tribe, guitar and harp, and today the interest in medieval instruments such as Lébeque, Lute and so on is on the rise.
As mentioned above, the types of string instruments are vowel type instruments including violin, viola, cello, double bass, guitar, harp, and the like. There are Korean string instruments such as 'Gayageum', 'Geomungo', 'Sugarbeet', 'Haegum', and 'Creamy'.
Typically, popular stringed instruments, violins and guitars, consist mainly of body and neck, two main parts. Both parts are made of wood. The body consists of a front plate (also referred to as a Belly, a Table, or a Soundboard) that forms the uppermost surface of the body, and a back plate ), And a side plate (also referred to as ribs) connecting the front plate and the back plate.
This body functions as a resonance to strengthen the vibration of the strings. The shape of the whole body looks like a waist, so it can be said to be similar to the human body. Inside the body is a sound post, which serves to transmit the vibration of the strings.
The neck is made of long, thin wood and includes a fingerboard. On the top of the fingerboard and the front plate there are several strands of strings, which vary according to the musical instrument. In the case of the violin, 4 lines and the guitar is 6 lines. Strings wrapped around each string are routed over a nut, running over the fingerboard, over a piece of wood called a bridge, to the tailpiece.
These stringed instruments make a sound when the bow rubs or strikes the string between the end of the fingerboard and the part where the bridge is located. At this time, the bridges supporting the strings also vibrate. The vibration is transmitted to the front panel, and some to the back panel. The holes formed on the front plate help to freely vibrate the underside of the instrument and serve as sound outlets from the instrument body. The shape of the hole formed in the front plate differs depending on the type of musical instrument.
Each of these string instruments has a unique tone color, and even if they are the same type of instrument, they have different tones due to a slight difference.
A tone is a characteristic of a sound that appears differently depending on a person or a musical instrument even if the pitch of the sound is the same, and it soon reaches a unique color of the sound that appears as a difference in waveform or frequency.
For example, the violin, which usually produces a four octave range of string instruments, produces a delicate, emotional treble that seems to break. Viola is lower than the violin and makes a slightly higher sound than the cello. Compared to the colorful and light violin, it is soft and heavy, a little darker and darker. In modern orchestra, the tone of viola tends to be emphasized. The cello, like the violin, has a wide range of four octaves and produces a strong, soft bass. The bass is dark and mysterious, and the treble is sharp and intense. It can be played fast and rhythmically, so it is often used as a solo performance. Double bass is responsible for the lowest range. The high range is a soft, appealing bass, and the low range is a dark and bizarre bass. The harp has a mysterious and fantastic tone as a chord that is produced by the resonance of a large and long sound.
These tones are mainly influenced by bridges, fingerboards, front plates, back plates, sound posts, and in particular, the sound posts are one of the factors that have a great influence on the tone. In the case of a violin, the sound post is installed in a column shape at an arbitrary position between the front plate and the back plate, as described above, and the tone varies greatly depending on the installation position. The sound posts are formed in a cylindrical shape having a predetermined length and are formed to have a predetermined length longer than the interval between the front plate and the back plate and moved at an arbitrary position between the front plate and the back plate so that the sound posts are left at the position where the best tone is emitted to adjust the tone. These tasks are usually performed by musical instrument experts.
However, since the sound posts are moved due to external shocks or storage errors, the users of general musical instruments may not actively replace them, or may attempt to arbitrarily adjust them, thereby causing harm to the tone.
In addition, the string instrument such as a guitar is not equipped with the above-mentioned tone color adjusting device, and thus there is a limitation in producing the best tone color.
Accordingly, in Korean Patent Laid-Open No. 10-2010-0120629, a piezoelectric element capable of converting the vibration and pressure of a string into an electrical signal is formed on a lower plate, and a sound post and a resonance generated in the upper plate is transmitted to the piezoelectric element and the lower plate through the sound post.
However, such a structure is structurally troublesome due to the provision of a separate piezoelectric element, and still can not escape the level of reliance on the position of the sound post.
Korean Patent Laid-Open Publication No. 10-2013-0072650 discloses a method for detecting a vibration generated by an acoustic pulse signal generated in a string while supporting a string generating vibration by a player, A main bridge base for holding the shape of the inner space formed in the auxiliary bridge portion from the outside and for supporting each constitution of the auxiliary bridge portion to be securely secured and for protecting from external impact, And a sound control unit for adjusting at least any one of a spatial sound effect and a gain through a mix of an externally input audio signal and a sound signal to generate a sound signal. .
This structure maintains the deep tone of the musical instrument while lowering the volume of the strings, and it can also provide the sound of expensive old musical instruments even by using a low price string, thereby effectively solving the demands of the tone of the musical instrument .
However, such a conventional structure includes a means for generating an electrical signal to the bridge, and the structure is complicated. Particularly, adjustment of a tone by an electrical signal is performed, There was a problem.
