Abstract

The invention relates to the wind instrument. Changing the magnitude of the air volume vibrated in the chamber produces the different sounds. Said instrument is of the dead chamber or the closed tube. Combining three sound holes with different areas can produce seven sounds. The advantages of the instrument is easy to operate. The chamber can be double or tripled. Thus, the instrument possesses the dual functions: moving mouth and pressing the holes. There are two shapes of the chamber: the shapes of the extended datestone and tube. The character of the instrument is that the chamber is closed or half-closed, the almost all chambers of the existed wind instrument are opened.

Description

Wind instrument

The present invention relates to the technical field of gas syrinx musical instrument.

At present, all known wind instruments, flat blowing all is a hole one sound, blowing seven sounds must have six holes.

The present invention provides a class novel wind instrument, and it is flat blows three holes and just can send out seven sounds, owing to its hole is few, thereby is called simple hole musical instrument, and the wind instrument hole in past is many, thereby is called numerous hole musical instrument, this simplified Chinese character in Chinese character and the meaning of the complex form of Chinese characters.

The invention of letter hole musical instrument, be to come according to the development that I have obtained the Whistle with eight tunes of patent, I am in the process of development Whistle with eight tunes, find the sort of difference with the sound hole combined area, change thorax internal vibration volume of air size and the rule of discharge sound preface, can rise to a kind of theory fully, it is fit to the outer wind instrument of all division sign classes, only, carry out these wind instruments the transformation of dead thorax and half-dead thorax once, here the half-dead thorax of Chenging, be according to spring syrinx musical instrument, need a venthole and find out, owing to opening in that afterbody is neither big nor small and claim half-dead thorax in this hole, be because Kong Taida, can make musical instrument become thorax alive, the combination pronunciation of can't three happy holes, too little and spring is sent out do not speak, it has a critical point, thereby is called half-dead thorax.

Crux of the present invention is interior thorax structure, two kinds of structures of its general employing, a kind of is the interior thorax of lengthening date core shaped, promptly clarinet, saxophone's unidirectional garden awl, make the two-way garden awl of stopped pipe into: another kind is that two of tubulose is not spacing with plane flute plug, but adopt positive flint face structure, we know that brass speculum, placed in the sun to generate enough heat to ignite dry gass is a kind of bronze sphere concave mirror with sun igniting of Ancient Chinese invention before 3,000 years generations, what modern radar, satellite earth antenna, speculum, searchlight all adopted is this principle, because sound wave is the same with light wave, electromagnetic principle of reflection.So sound wave is concentrated the reflection vibration at tubulose two by positive flint face, guaranteed that from face body discharges the sound preface with sound hole combined area size, and the brass speculum, placed in the sun to generate enough heat to ignite dry gass face makes also the body pronunciation sensitive, so from now on flute, crust crow, flute of suggestion, use sun face flute plug then instead.Outside the afterbody venthole except above-mentioned positive flint face structure and spring crying musical instrument, other is the same with the Whistle with eight tunes that obtains patent fully, frankly speaking, but is the reprint or the clone of Whistle with eight tunes principle.

Certainly, in order to change tone color, can also be according to principles of geometrical acoustics, adopt other all approximate above-mentioned two types thorax body, but generally speaking, with above-mentioned two kinds of structure the bests, as should not change, and, change tone color and also have other way, such as changing with material acoustics, material acoustics comprises two aspects: the one, and material pronunciation acoustics, the 2nd, material reflection sympathetic response acoustics, all can change tone color at any change of this two aspect.

Advantage of the present invention is: one, it makes musical instrument easy and simple to handle, and might open the foolization the gate, we know that the foolization has only the Japanese to realize on camera.Two, because a hand saved in three hole seven tunes, this just lays the foundation for musical instrument adds thorax expansion range again, thereby the two thoraxes or the three thorax wind instruments of high bass can appear, this especially as 2 bedrooms or three-bed room are removed in a room, or it is the same that the monotubular shotgun has been made into bitubular shotgun, because just there are 14 sounds in six holes, its benefit is tangible, and this also is unique a kind ofly not only can but also can move the difunctional musical instrument of mouth by the hole, and we know the musical instrument that moves mouth, are can not be by the hole as panpipes, mouth organ.And be to move mouth by the musical instrument in hole as flute, clarinet, but such one simple hole has just solved above-mentioned contradiction once.

Below in conjunction with accompanying drawing and specific implementation method the present invention is done further detail explanation.Figure (one) is two thorax disjunctor flutes in a simple hole, big thorax is that bass thorax, little thorax are the high pitch thorax, differ octave between them, wherein a left side (1) and the right side (1) are each thorax mouthpiece, and a left side (2) and right (2) are that little sound hole, a left side (3) and the right side (3) of pressing of each thorax pressed sound hole for pressing sound hole, a left side (4) and the right side (4) in each thorax greatly for each thorax.The two sides of two of flute and middle blocking-up flute plug all is the brass speculum, placed in the sun to generate enough heat to ignite dry gass concave surface, and the radius-of-curvature of concave surface has one to be the sensitiveest, can not provide here, needs own repetition test.

When playing wind instruments and to blow common flute be living, be identical then with Whistle with eight tunes by the hole pronunciation.Figure (two) is the suona horn of a duplex, and its structure has the venthole except the pronunciation spring whistle with at thorax body afterbody, and other fundamental sum Whistle with eight tunes roughly the same.Wherein to send out fundamental tone be 1 to three hole full cut-offs, and opening the aperture pronunciation is 2, and opening the mesopore pronunciation is 3, and opening the pronunciation of aperture and mesopore simultaneously is 4, and the wide-bore pronunciation is 5, and wide-bore and mesopore pronunciation simultaneously is that 6, three hole standard-sized sheets pronunciations are 7, totally seven sounds.

Claims

(1) allly changes thorax internal vibration volume of air size and discharge all kinds of mouthpieces, the arris of the series of sound, the simple hole wind instrument of spring ring with happy hole combined area difference.
