Description

Three-stringed bowed instrument

Technical Field

The utility model belongs to the technical field of the musical instrument, in particular to three-stringed bowed instrument.

Background

The existing urheen only has two strings, the range of sound is very narrow, especially bass cannot be played, and some songs with wide range of sound cannot be well deducted. In the conventional deduction, the problem that the bass cannot be performed in such a tune is often solved by raising the pitch of the entire tune. But this makes the performance effect worse. In addition, the conventional erhu cannot play harmony.

Disclosure of Invention

The utility model aims at overcoming the defects that the prior art has narrow range and can not play harmony, providing a three-stringed bowed instrument with wide range and can play harmony.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a three-stringed bowed instrument, includes a musical instrument section of thick bamboo, the musical instrument pole of rigid coupling on a musical instrument section of thick bamboo, first musical instrument string, than the thick second string of first string, than the thick third string of second string, be used for adjusting the bass musical instrument axle of third musical instrument string, be used for adjusting the alto musical instrument axle of second string, be located the first bow hair between third musical instrument string and the second string, be located the second bow hair between second musical instrument string and the first string, be used for supporting the bow member of first bow hair and second bow hair, be used for preventing the second bow hair from rubbing the anti-touch steel wire of second string, the second string is located between first string and the third string, anti-touch steel wire lower extreme rigid coupling is at a musical instrument section of thick bamboo downside, the anti-touch steel wire upper end passes the back rigid coupling from between second string and the third musical instrument string at a musical instrument pole lower extreme. The second string is arranged in the middle of third string and first string, and wherein the third string is closest to the health, accords with operating logic more, in addition, sets up and prevents touching the steel wire, thereby the second bow hair friction mediant sound prevents that the mediant sound from interfering when fine prevention plays the bass. In addition, through the adjustment of the right hand, the second bow hair rubs the second string, and bass and mid-tone harmony can be realized.

Preferably, the first bow hair is located at a lower height than the second bow hair. The first bow hair is convenient to operate by the ring finger, so that the first bow hair can easily rub the third string.

Preferably, one end of the bow rod is fixedly connected with a second connecting block connected with the second bow hair, and a first connecting block connected with the first bow hair is arranged below the second connecting block. The structure is simple.

Preferably, one end of the second connecting block, which is far away from the second bow hair, is connected with the connecting block, and one end of the first connecting block, which is far away from the first bow hair, is connected with the connecting block. The structure is simple.

Preferably, the first connecting block and the second connecting block are fixedly connected with hooks, and the end parts of the first bow hair and the second bow hair are hooked on the corresponding hooks. The installation is simple.

Preferably, one end of the bow rod close to the hand is provided with a slingshot for binding the second bow hair to the bow rod. The elastic rope enables the second bow hair to be far away from the second string, so that interference when bass is played is avoided.

Preferably, the upper end of the anti-touch steel wire penetrates through the piano rod and then is fixed on the piano rod. The fixation is firm.

The utility model has the advantages that: the utility model provides a three-stringed bowed instrument, range is wide, can play harmony. In the embodiment, bass is widened, and the added third string and the second string can form 4 degrees, 5 degrees or even 8 degrees; greatly enriches the expressive force of bass and harmony which the urheen does not have, and ensures that some music which cannot be played can be realized on the urheen.

In the figure: the piano comprises a piano barrel 1, a piano rod 2, a third piano string 3, a second piano string 4, a first piano string 5, a bass shaft 6, a mediant piano shaft 7, a treble piano shaft 8, a first bow hair 9, a second bow hair 10, a bow rod 11, a hand 12, a second connecting block 13, a first connecting block 14, a connecting block 15, a bouncing rope 16, an anti-touch steel wire 17 and a hook 18.

Detailed Description

The invention will be further explained in detail with reference to the drawings and the following detailed description:

example (b):

referring to fig. 1 to 6, a three-stringed bowed instrument includes a barrel 1, a rod 2 fixedly attached to the barrel 1, a first string 5, a second string 4 thicker than the first string, a third string 3 thicker than the second string, a bass shaft 6 for adjusting the third string 3, a alto shaft 7 for adjusting the second string 4, a treble shaft 8 for adjusting the first string 5, a first bow hair 9 between the third string 3 and the second string 4, a second bow hair 10 between the second string 4 and the first string 5, a bow bar 11 for supporting the first bow hair 9 and the second bow hair 10, a touch-proof wire 17 for preventing the second bow hair 10 from rubbing against the second string 4, the second string 4 is positioned between the first string 5 and the third string 3, the lower end of the anti-touch steel wire 17 is fixedly connected with the lower side of the barrel 1, the upper end of the touch-proof steel wire 17 penetrates between the second string 4 and the third string and then is fixedly connected to the lower end of the piano rod 2. The upper end of the anti-touch steel wire 17 passes through the piano rod 2 and then is fixed on the piano rod 2.

The height of one end of the first bow hair 9 close to the hand 12 is lower than that of one end of the second bow hair 10 close to the hand 12; one end of the bow rod 11 is fixedly connected with a second connecting block 13 connected with the second bow hair 10, and a first connecting block 14 connected with the first bow hair 9 is arranged below the second connecting block 13. One end of the second connecting block 13, which is far away from the second bow hair 10, is connected with a connecting block 15, and one end of the first connecting block 14, which is far away from the first bow hair 9, is connected with the connecting block 15. Hooks 18 are fixedly connected to the first connecting block 14 and the second connecting block 13, and the ends of the first bow hair 9 and the second bow hair 10 are hooked on the corresponding hooks 18. One end of the bow rod 11 close to the second connecting block 13 is provided with a slingshot 16 for binding the second bow hair 10 to the bow rod 11.

Principle of embodiment:

when playing, the third string 3 is positioned between the second string 4 and the body, and the first bow hair 9 and the second bow hair 10 are positioned between the body and the bow bar 11.

The hand 12 is defined herein as the right hand.

Referring to fig. 4, when a user plays a bass, the ring finger of the right hand abuts against the first bow hair 9, when the user needs to play a bass, referring to fig. 5, the ring finger exerts force, the first bow hair 9 deforms to be close to the third string 3, the first bow hair 9 rubs against the third string 3, meanwhile, the right hand slightly draws close to one side of the body, at the moment, the second bow hair 10 abuts against the anti-touch steel wire 17, the second bow hair 10 is far away from the second string 4 by taking the anti-touch steel wire 17 as a fulcrum, and therefore interference caused by friction of the second bow hair 10 and the second string 4 is prevented, on the other hand, the elastic rope 16 is bound at one end of the second bow hair 10, so that one end of the second bow hair 10 is close to the bow rod 11 enough, and interference of the second bow hair 10 on the bass playing is also avoided.

And when harmony needs to be played, namely when bass and mediant need to be played simultaneously, the right hand need not be drawn close to the body, see fig. 6, second bow hair 10 can not lean on preventing touching steel wire 17, and at this moment, second bow hair 10 rubs second string 4, and first bow hair 9 rubs third string 3, harmony appears.
