Description

Erhu with independent jack of inner and outer strings

Technical Field

The utility model belongs to the field of musical instruments, and particularly relates to a urheen with independent jacks for inner strings and outer strings.

Background

The urheen is a Chinese traditional string instrument, and the tone of the urheen is almost the same as that of a human voice, and has singing performance and complaint feeling. At present, the common two-stringed bowed instrument shares a jack with two strings, and the fixed tone is d ¹ a ¹ If in a musical compositionOccurs below d ¹ The tone is played by 8 degrees, so that the tone is quasi-played, and in order to solve the problem, a double-jack erhu is also disclosed, for example, CN 206163105U discloses an extended bass erhu, the two strings are respectively provided with a double-string shared jack, the upper part is a fixed jack, the lower part is a movable jack, if the bass syllable is needed, the lower jack is not enabled by manual operation, the upper jack is enabled, if the bass is not needed, the lower jack is enabled by switching, the upper jack is disabled, and the common erhu can extend a pure 4-degree range to a bass region, so that the tone quasi-problem of the bass playing of the erhu is solved. However, the two-jack erhu has the following disadvantages: 1. the two jacks are required to be continuously switched during playing, so that the smoothness of music playing can be affected, and the defects are more prominent particularly during playing of rapid-sound type music; 2. the movable jack needs to be manually switched during playing, thus increasing the burden of manual operation and leading the mechanical start and stop to have noise. 3. If the influence of jack switching on the fluency of music is reduced, the jack can be temporarily not switched to play the role of the jack when playing the rapid-speed music, but the cost is that the original position and fingering must be changed, the finger habit is changed, and the playing difficulty is increased.

Disclosure of Invention

The utility model aims to solve the technical problems in the prior art and provides the urheen with the independent jack with the inner chord and the outer chord.

The technical scheme of the utility model is as follows: the utility model provides a two-stringed bowed instrument with independent jack of inner and outer string, includes a musical instrument section of thick bamboo, a bridge, bow, set up the musical instrument of a musical instrument section of thick bamboo side, set up the interior musical instrument axle and the outer musical instrument axle in bridge upper portion, its special character is: an inner string jack and an outer string jack are arranged from top to bottom on the bridge below the outer string shaft, an inner string is arranged among the inner string shaft, the inner string jack and the bridge, an outer string is arranged among the outer string shaft, the outer string jack and the bridge, and d of the inner string is arranged among the outer string shaft, the outer string jack and the bridge ¹ The sound position corresponds to the position of the outer string jack, and the vertical distance from the position of the outer string bound by the outer string jack to the piano stem is larger than that of the inner string bound by the inner stringThe vertical distance from the jack binding part to the piano rod is the same as that of the inner string and the outer string, which are staggered from front to back and are flush along the front-back direction at the position below the outer string jack.

Further, the position of the inner chord bound by the inner chord jack is adjustable in the left-right direction and the front-back direction.

Further, the front-rear distance between the inner chord and the outer chord below the position corresponding to the outer chord jack is more than or equal to 3mm.

Further, the distance between the outer chord jack and the inner chord jack is 110-120 mm.

Further, the vertical distance from the outer string bound position to the bridge is 15-25 mm, and the vertical distance from the outer string bound position to the bridge is larger than the difference of the vertical distances from the inner string bound position to the bridge is 3-7 mm.

Further, the inner string is regulated in the front-rear direction by the inner string jack binding position through sleeving a replaceable bushing on the outer string shaft corresponding to the inner string passing position. The front and back positions of the part of the inner string bound by the inner string jack can be adjusted by changing the bushings with different thicknesses, so that the distance between the inner string and the outer string jack is changed, and the playing d by the thumb is prevented ¹ And when the sound is lower than the bass, the inner strings are contacted with the outer string jacks to generate noise.

Further, the adjustment of the position of the inner string restrained by the inner string jack in the left-right direction is realized by changing the length of the inner string jack so as to meet the flush requirement of the section of the sound level and the double strings below the outer string jack.

The beneficial effects of the utility model are as follows: simple structure, low manufacturing cost and can realize bass expansion. An outer string jack is arranged at the position of a conventional two-stringed Chinese fiddle jack on the bridge, an inner string jack is fixedly arranged at a proper position between the outer bridge and the outer string jack, the inner string is bound through the inner string jack, and the outer string is bound through the outer string jack. The inner string jack has the function of expanding a pure 4-degree range to a bass region, wherein the inner string of the fixed string is a sound, and the outer string is a sound ¹ The sound can meet the requirement of the sound level when playing music, and basically does not need to change the original fingering and the position (only the inner string and the empty string have a changeable sound)And (3) chemical conversion). The position of the outer string jack can meet the requirements of the outer string jack on the front and back flush and tone fixing of the inner string and the outer string of the string bridge, in order to simultaneously meet the requirements of the inner string and the outer string of the section between the inner string jack and the outer string jack, the outer string is higher than the inner string by a large included angle, so that a difficult problem occurs, if four fingers are used for playing the b tone of the inner string, the b tone cannot be pressed by the conventional four fingers because the outer string is higher than the inner string, but because the included angle of the two strings is larger, a condition is provided for pressing the two tones by the thumb, and therefore, the two-finger five-finger playing method of the thumb is added on the basis of the conventional four-finger playing method, and the c1 tone can be pressed by the thumb or other four fingers. According to the playing practice, the four-finger playing method is changed from the four-finger playing method to the five-finger playing method, the problem that the four fingers of the independent double-jack two-stringed bowed instrument cannot be used for playing by one finger is solved, and a good playing effect is achieved.
