Description

Three-stringed bowed instrument with double sound-film

The utility model is the improvement of national musical instruments.

Urheen is the main national stringed instrument of China, is widely used in accompaniment, (instrumental) ensemble and solo, and its tone color is simple and honest, soft and graceful.But it is narrow to have remained range, and volume is less, and the high position decay is serious.Effective range of sound is two octaves only, and the epithelium vibration easily produces weak points such as wolf sound.

In order to overcome above-mentioned deficiency, many Erhu playings and wright carried out reform to urheen." music exploration " second phase in 1984 is introduced to be had " two film trichord reform Chinese fiddle ", its principal feature is to increase a bass g string is arranged, and so that the Chinese fiddle jacket casing is on an anistree two-stringed piano drum in the flat anise, inner core is shorter than urceolus, and inner core upper plate and urceolus upper plate inboard compose one.Formed a kind of telescopic pair of film qin tube, added by the little curved qin bar of arc, very heavy, two qin sign indicating numbers, three qin axles and bow etc. and form " two film Three-stringed erhu ".This Three-stringed erhu also makes range expand five degree downwards except that keeping former urheen tradition tone color and performance method.Increase volume, eliminated the wolf sound, and increased new skills such as playing two strings, enriched the expressive force of urheen.But, because wiping on the string point bow, moves by telescopic qin tube, make the HFS pronunciation by the damping of outer qin tube in addition.Thereby simple and honest, the soft and graceful tone color of former urheen weakens to some extent, though once taked to offer measures such as sound window on qin tube plate, still feels undesirable.

The utility model has designed a kind of two films three Hus with compound qin tube, is intended to overcome the deficiency that former telescopic pair of film Three-stringed erhu exists.

Compound qin tube (Fig. 1) is by positive anistree two-stringed piano drum (upper plate 1, three blocks of plates 2 in right side, lower plate 3, the three blocks of plates in left side 4 are formed) upper and lower plate 1,3 prolong 16～20 millimeters left, form the outer middle Chinese fiddle tube (Fig. 2) of flat anise with three blocks of plates in outer left side 5, the epithelium 6 of positive anistree two-stringed piano drum covers in qin tube end face, becomes 86 ° of angles with qin tube axis.The epithelium 7 of Chinese fiddle tube covered in the urceolus end face during flat anise was outer.Become 97 ° of angles with qin

tube axis.Epithelium

6 and 7 center distance are 10～15 millimeters.Upper edge between two epitheliums of qin tube plate 1 offers an oval string hole 8, can fully vibrate so that two urheen strings therefrom pass ， And.

The epithelium illiteracy puts face and there is certain angle qin tube axis, its objective is to bow hair and string are drawn to be the orthogonal operation when playing.Arrow shown in Fig. 29 is bow hair traffic direction, can obtain best voice effect like this.

Compound qin tube can be made the supporting musical instruments of seriation such as two film three actions Hus and two film trichord Da Hu according to corresponding proportion.

Adopt compound qin tube not only can keep the tone color characteristics of urheen and middle Hu, and make its tonequality pure more solid, tone color is simple and honest, soft and graceful and be rich in sympathetic response and penetration power.

Fig. 1 is the front elevation of compound qin tube.

Fig. 2 is the vertical view of compound qin tube.

Embodiment: positive anistree two-stringed piano drum is by the ministerial standard SG147-78 of Ministry of Light Industry, qin plate 1,3 prolongs 18 millimeters left, two epithelium center distance be 12 millimeters for good, be added with the little curved qin bar of arc, qin sign indicating number, very heavy, bow etc. again, just can make the two films three of high-quality recklessly.
