Abstract

The utility model discloses a blowing wind instrument-piston flute xiao capable of playing music, comprising a piston, a blowing tube, and a support bar. Various portamentos and tone scales can be played by the piston flute xiao. The piston is used to directly move in the sound tube by the piston flute xiao, and the pitch of speech sound is obtained by the useful length of the intercepted sound tube, solving the problems that the wide span portamento is more difficult to play or the effect is bad for the existing traditional musical instruments. Two straight tubes with different thickness and regular inner diameter are taken as sound bodies by the piston flute xiao, the lower tone zone is played by the thicker tube, and the higher tone zone is played by the thinner tube. A piston matched with the inner diameter of the tube is arranged in each sound tube, and the piston is connected with the support bar, and the piston is driven to glide up and down by the support bar when the piston flute xiao being played. The upper end of the sound tube is taken as a blowing opening to blow air in the tube. Different pitch of speech sounds are emitted by resonating the sound tube useful length intercepted by the piston and the airflow. Different tone colors and sound effects can be produced owing that the sonification theory and playing methods of the piston flute xiao are different from the existing wind instruments.

Description

Piston flute xiao

Affiliated technical field

The utility model relates to a kind of tongue that can perform music, especially relates to a kind ofly being made up of piston, blowpipe and support bar, can play the Piston flute xiao of various glides and scale.

Background technology

At present, generally be divided into two big classes in the tongue that everybody understands, 1, Chinese national tongue; Comprise: flute, vertical bamboo flute, panpipes, suona horn, pipe, an ancient egg-shaped, holed wind instrument, crust crow etc.2, western wind instrument; Comprise: flute, clarinet, oboe, trumpet, circular horn, trombone, saxophone etc.These musical instruments have features such as the pronunciation principle, tone color, playing method of self respectively, but do not have a kind of wind instrument to be to use piston directly to move in pronunciation tube, intercept the pronunciation of pronunciation tube effective length.Can glide except that trombone, the such national musical instruments of other musical instruments or similar panpipes be played large span glide relatively difficulty or poor effect.

Summary of the invention

The purpose of this utility model provides a kind ofly can easily play glide, with tone color characteristics, playing effect, playing method, the expressive force of existing wind instrument the tongue of difference is arranged.

The technical solution of the utility model is: the straight tube with two thickness differences, internal diameter rule is made sounding body, adorns a piston that mates with this bore in every pronunciation tube, and piston is fixed on the support bar, and support bar can drive piston and slide up and down.Mouthpiece is made in upper end with pronunciation tube, blows in pipe, and air-flow sends different pitches with the effective length resonance of pipe inner carrier intercepting.Pipe thicker in the two tubes is played the lower range of sound, and thinner pipe is played the higher range of sound.

The beneficial effects of the utility model are, drive piston by support bar and slide up and down in pronunciation tube, directly intercept the pronunciation tube effective length, can make things convenient for modulation and play glide, can obtain the pitch beyond the scale in this musical instrument range, the convenient differential sound of playing belongs to on-fixed pitch musical instrument.At aspects such as tone color, playing method, expressive forces is that the useful of existing wind instrument replenished.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Figure [1] is an embodiment structural drawing of the present utility model.Figure [2] is the single tube sectional view of figure [1].

The title at each position is in figure [1] [2]: (1) musical instrument mouthpiece, (2) pronunciation tube, (3) piston, (4) support bar, (5) chute, (6) bottom plug, (7) draw ring, (8) fixed screw, (9) nut, the product of (10) mark phoneme.

Embodiment

In the embodiment shown in figure [1] [2], (2) are pronunciation tube, and as the mouthpiece of musical instrument, whole musical instrument is formed with two tubes (1), arrangement from coarse to fine.Each root pronunciation tube must the internal diameter unanimity, and the tube wall thickness is even, is that materials processing can with plastics, metal, wooden, bamboo matter.A piston (3) that mates with this bore is installed in pronunciation tube (2), and piston (3) links to each other with support bar (4).(8) be fixed screw, fixed screw is divided into two parts up and down to pronunciation tube, and when piston (3) moved downward the position of fixed screw (8), fixed screw (8) blocked piston, piston can not be moved downward again, and the position of fixed screw (8) is the fundamental tone (double bass) of this pipe.A bottom plug (6) is arranged in the lower end of pipe, an aperture (as figure [2]) is arranged in the middle of the bottom plug (6), one end of support bar (4) is by outside the aperture protruded tube, a nut (9) is equipped with in the lower end of support bar (4), make the support bar Shi Buhui that moves upward break away from aperture in the middle of the bottom plug (6), like this, pull bar can keep parallel with pipe and can not roll.The lower semisection of pipe is opened an elongated slit and is made chute (5) between (6) and (8), the draw ring (7) that is used to control pitch links to each other with support bar (4) by chute (5).It is basic that the principle of Piston flute xiao is to use piston intercepting pronunciation tube effective length, belong to on-fixed pitch musical instrument, accuracy in pitch is not easy to grasp, therefore, open the product (10) that some osculums are used as the mark phoneme on one side of chute (5), it is smooth that another side keeps, so that play sliding up and down of glide and draw ring (7).Tongue Yin Wendu is different, and pitch can change, so design a Pitch Fine device in musical instrument.Draw ring (7) is connected to revocable with support bar (4), in the middle of the support bar (4) is screw, one end of draw ring (7) is a nut, turn the contacting points position of nut (9) change draw ring (7) and support bar (4), can adjust the distance between piston (3) and the draw ring (7), adjust piston up and down position in blowpipe, fine setting makes actual pitch consistent with the desired pitch of product (10) of mark phoneme.

Piston flute xiao pronunciation tube one end is by piston closes, and the other end also is the gas outlet as mouthpiece simultaneously, belongs to the stopped pipe tongue, the method of blowing is close with the performance panpipes, mouthpiece is towards just going up during performance, and left hand is held musical instrument, and the corresponding draw ring of right hand push-and-pull and pronunciation tube is played.
