Abstract

The utility model discloses a saw type music instrument the shape of which is similar to the shape of a steel sheet, comprising a body in right-angle trapezoid shape and a clamp shelf. The utility model is characterized in that a section of an oscillation board without saw tooth is arranged in the body. The utility model has the advantages of wide range, sonorous and agreeable sound, soft and firm tone color, suitability for daily entertainment and play, and availability as a cutting tool. Consequently, the saw type music instrument can combine art with practicability.

Description

Saw type music instrument

The utility model relates to a kind of musical instrument, is a kind of saw qin that is similar to the steel disc handsaw.

The steel disc handsaw is common a kind of cutting tool, and people utilize this steel disc handsaw to carry out amusement sometimes, can play out some simple melodies.For example, there is a kind of steel disc handsaw in the U.S., and the same right-angle triangle (right-angled trapezium) that scabbles a wedge angle of shape has sawtooth on the hypotenuse, on the short right-angle side handle is housed, and long right-angle side is as playing the limit.Can play out simple melody with this saw, tone color still can, but that the essence shortcoming is a range is narrow, especially its tone color of bass area is very poor, so, can not be as the melody of formal performance.

The utility model provides a kind of range broadness, and pronunciation is doted on bright, melodious, the firm saw qin that supplies the music circles to play of residence during tone color is gentle.And this saw qin can be played as musical instrument, can be used as the sawmilling instrument again, so both increased a kind of musical instrument, becomes a kind of art and the practical utensil that combines again.

The utility model saw qin is made up of a body and a holding frame made from sheet steel.Body is divided into keynote plate and vibration plate two parts, promptly before the body, the middle part is the keynote plate, is similar to a right-angled trapezium, has sawtooth on its oblique waist; The body rear portion is similar to a rectangle for the vibration plate.Holding frame is fixedly mounted on the end of rectangle vibration plate.

The inventor has carried out long-time examination to the utility model saw qin and has played and improve, obtain obtaining satisfied playing effect at following physical dimension scope Nei Shiben saw qin: body is made with 65 manganese steel, hardness is HRA65～76, body thickness is 0.85～1.25mm, total length is 600～800mm, and the plate length of wherein vibrating is 100～300mm, and the body head is wide to be 25～48mm, afterbody is wide to be 130～180mm, and sawtooth is 5～No. 8 flute profiles.

The basic skills that above-mentioned saw qin is played is: holding frame is clamped in the middle of two legs, the body head of playing the erhu on the other hand, another hand behaviour bow, during performance, draw position, the different range of sound on body keynote plate plate ridge " string " length direction according to melody with the bow wiping, simultaneously, hold the finger control keynote plate of body head and make S deformationization, can play out music easy on the ear.

Therefore, because the utility model saw qin has structurally been set up one section vibration plate, and has made optimal design on physical dimension, just increased the sympathetic response zone of the high and low sound of this saw qin, make the range at high pitch position expand to two groups of a of small character ², the range at bass position expands to small character group f.

Accompanying drawing is depicted as structural representation of the present utility model.Wherein: 1 is the keynote plate, and 2 are the vibration plate, and 3 is support, and 4 is sawtooth.

Embodiment of the present utility model as shown in drawings.Known that by figure the body of this saw qin is made of keynote plate 1 and vibration plate 2, has sawtooth 4 on the oblique waist of keynote plate 1, holding frame 3 is fixedly mounted on the end of body vibration plate 2.In the present embodiment, body is made with high-quality 65 manganese steel, and reach quenching hardness IIRA73～75, body keynote plate 1 head (end on the right-angled trapezium) is wide to be 40mm, and afterbody (end under the right-angled trapezium) is wide to be 150mm, and body vibration plate 2 is width such as 150mm, the long 760mm of whole body, length comprising vibration plate 2 is 200mm, and body thickness is 0.95mm, and sawtooth 4 adopts No. 8 flute profiles.
