Abstract

The utility model discloses a double gamut multi-timbre urheen, which comprises a sound tube and an instrument stem, wherein the urheen comprises a double sound tube, a movable auxiliary sound tube is arranged in the sound tube; a gap is formed between the auxiliary sound tube and the sound tube; and a changeover device is arranged on the instrument stem and is connected with the auxiliary sound tube. The sounding of the sound tube or the auxiliary sound tube can be chosen by controlling the displacement of the auxiliary sound tube. The timbre of the urheen is beautified and the sound volume is increased by adding facilities in the sound tube. The utility model has the effect that the sound tube and the auxiliary sound tube can respectively sound, therefore the gamut of the urheen is doubled, the timbre is improved, the gamut of the urheen is increased, the timbre is beautified, the urheen is the convenient for use, and the specific gravity is balanced.

Description

Double-tone territory multitone look Chinese fiddle

One, technical field

The utility model belongs to the musical instrument manufacturing technology, is specifically related to the improvement to Chinese fiddle.

Two, background technology

Chinese fiddle generally also claims urheen, can specifically be divided into urheen, middle Hu, recklessly high again according to the difference of range tone color; In addition jinghu, the bowed stringed instrument with a thin wooden soundboard or the like close with it.Urheen is the national musical instruments that China has long history, the tone color that it is graceful, and abundant expressive force is firmly got liking of China broad masses of the people, is particularly suitable for the performance and the accompaniment of China's folk song and opera, has the good reputation of east violin.But urheen has only two strings, and mainly in two octave ranges performances of D, A string, the tonequality volume of the 3rd octave range just reduces relatively and reduces, so its song is played and significant limitation has just been arranged on the creation.

Reform for Chinese Musical Instruments, existing a lot of people have made many-sided exploration and contribution, the bowed instrument of China has been significantly improved with the workmanship aspect technically and has improved, but also comes with some shortcomings, and does not also solve as the range of the urheen problem of widening.The improvement practice of widening the urheen range at present is comparatively simple, as two a thousand pieces of gold urheens, portable a thousand pieces of gold urheen, though range widen, but too little, just improved two, the tierce territory, the intensity of string and fixing the position is not easy to play.

Three, summary of the invention

The purpose of this utility model provides a kind of double-tone territory multitone look Chinese fiddle, the range of Chinese fiddle can be doubled also to improve tonequality and volume, and it is convenient to play.

The technical solution adopted in the utility model is: double-tone territory multitone look Chinese fiddle comprises sound tube and qin bar, and it has the double-tone tube, and a secondary sound tube is set in the sound tube, and secondary sound tube is movable; Gapped between secondary sound tube and the sound tube.Be provided with conversion equipment on the qin bar, conversion equipment is connected with secondary sound tube.

Conversion equipment can make the port of secondary sound tube be close to or leave the qin skin, can select by the still secondary sound tube pronunciation of sound tube pronunciation by the displacement of controlling secondary sound tube.When secondary sound tube was close to the qin skin, Chinese fiddle became secondary sound tube pronunciation, can improve the height of octave; Leave the qin skin and work as secondary sound tube, it is unsettled in the sound tube, and Chinese fiddle is by sound tube normal articulation.Equal two qins and play in conversion, a qin micromicro sends the sound of two qins.And the tone color of qin is beautified by the additional facilities in the secondary sound tube, increase volume.

The nose heave body of existing urheen is light, the body shakiness, and the utility model has increased secondary sound tube and conversion equipment in the bottom of qin, and the each several part that makes qin is than rebalancing method, and such Erhu playing gets up and uses freely more, and is steady as a rock.

The utlity model has the effect that sound tube and secondary sound tube are pronounced respectively, make the range of Chinese fiddle expand one times, tone color also changes.The range of Chinese fiddle has been increased, and tone color has beautified, the user, than rebalancing method.

Five, embodiment

Double-tone territory multitone look Chinese fiddle comprises qin bar 1, string 2, qin sign indicating number 3, qin holder 4, sound tube 5 and Qin Pi 8 etc., and string 2 is tightened on the qin skin 8 through qin sign indicating number 3.A secondary sound tube 7 is installed in sound tube 5, gapped between secondary sound tube 7 and the sound tube 5, can the front and back activity freely.The port of secondary sound tube 7 is parallel with qin skin 8, and the rear portion connects conversion equipment 6.On secondary sound tube 7 spring 17 is arranged, the effect of spring 17 makes secondary sound tube 7 be close to qin skin 8.

Conversion equipment 6 of the present utility model is installed on the qin bar 1, conversion equipment 6 is made of depression bar 9, slideway 10, shift fork 11 and pole 12, is with spring 13 on depression bar 9, in spring 13 outsides sheath 14 is arranged, sheath 14 had both played beauty function, also made the stroke limit that presses down of depression bar 9.On sound tube 5, have open-work, slideway 10 is installed in qin bar 1 side, depression bar 9 is inserted in the slideway 10, cutting ferrule 15 is arranged, on the cutting ferrule 15 projection is arranged in slideway 10 bottoms with qin bar 1 joint; Depression bar 9 lower hinge shift forks 11, shift fork 11 is connected with pole 12, and pole 12 other ends are hinged on the column 16 at secondary sound tube 7 rear portions.When depression bar 9 presses down, rotation when shift fork 11 is run into cutting ferrule 15 protruding, when openhanded opening, spring 13 is depression bar 9 position of rebounding, and shift fork 11 rotates when running into cutting ferrule 15 protruding again.The rotation of shift fork 11 makes the pole 12 straight or transpositions of tilting, and when pole 12 was tilted, spring 17 was pressed to secondary sound tube 7 on the qin skin 8, and this moment, Chinese fiddle changed secondary sound tube 7 pronunciations into.And when pole 12 was straight, secondary sound tube 7 was withstood by pole 12 and leaves qin skin 8, and this moment, Chinese fiddle was 5 pronunciations of sound tube.

On secondary sound tube 7 pronunciation board 18 is arranged, pronunciation board 18 is two ends and the straight plate that secondary sound tube 7 inwalls are connected, and is installed in secondary sound tube 7 ports.Only soundboard 19 can also be arranged on secondary sound tube 7, and it is concordant with secondary sound tube 7 ports to end soundboard 19.The general area that ends soundboard 19 is about 1/5th of secondary sound tube 7 port areas, only on the soundboard 19 a plurality of open-works is being arranged.When conversion equipment action, when Chinese fiddle becomes secondary sound tube pronunciation, end soundboard 18 and be close on the qin skin, make a part of qin skin can not vibrate (the sound mode is sealed in employing), the high pronunciation recklessly of imitation.
