Description

A kind of vertical bamboo flute

Technical field

The utility model relates to musical instrument technical field, particularly a kind of vertical bamboo flute.

Background technology

Vertical bamboo flute is a kind of very ancient Han nationality's blowing instrument, and be generally made up of bamboo, mouthpiece is in the upper end of vertical bamboo flute body.Vertical bamboo flute of a great variety, can be divided into six hole vertical bamboo flutes and octal vertical bamboo flute by the quantity difference of sound hole, can be divided into Tang Xiao, vertical bamboo flute and Nan Xiao etc. again by the difference of mouthpiece shape, wherein the mouthpiece of Tang Xiao is circumscribed crescent, and the mouthpiece of vertical bamboo flute and Nan Xiao is then in interior " U " shape.When playing the flageolet, air-flow is by mouthpiece place sounding, from physical angle analysis, its principle is: be split into two parts during the arris of air-flow by mouthpiece place, wherein a part of air-flow flows through through vertical bamboo flute body outer wall, another part air-flow then forms standing wave in flowing pipe, when air-flow is rived and the inwall of vertical bamboo flute shake, thus reach the effect of sounding.The various vertical bamboo flutes occurred in the market, because its vertical bamboo flute body is generally straight tube-like, the overall wall thickness of vertical bamboo flute body is all roughly equal, the defect of this structure is: when the arris of air-flow by mouthpiece place, only have small part of gas can enter in pipe, the air-flow of the overwhelming majority can flow through from pipe outer wall, causes the bass volume when playing wind instruments lower, sympathetic response intensity is more weak, and then causes playing effect not good.

Utility model content

The purpose of this utility model is defect for prior art and deficiency, provides a kind of simple and reasonable, bass is louder and clearer, sympathetic response is more abundant vertical bamboo flute.

For achieving the above object, the utility model is by the following technical solutions:

A kind of vertical bamboo flute described in the utility model, comprise vertical bamboo flute body, the top of described vertical bamboo flute body is provided with mouthpiece, described mouthpiece place is provided with arris, the top of described vertical bamboo flute body is arranged with the thick bamboo tube with described mouthpiece corresponding matching, the top of described thick bamboo tube is provided with the tangent plane with described arris corresponding matching, and the gradient of described tangent plane is equal with the gradient of described arris.

Further, the upper surface of described thick bamboo tube is mutually concordant with the upper surface of described vertical bamboo flute body.

Further, described vertical bamboo flute body comprises top tube and down tube, and described upper pipe is detachably connected with described lower pipe, and the top of described upper pipe is provided with described mouthpiece.

The beneficial effects of the utility model are: the utility model thick bamboo tube with mouthpiece corresponding matching sheathed on the top of vertical bamboo flute body, and the tangent plane with arris corresponding matching is set on the top of thick bamboo tube, the gradient of this tangent plane is equal with the gradient of arris, by arranging said structure, compared with prior art, increase effectively the wall thickness at mouthpiece place, when making to blow, air-flow can be pressed darker, thus add the airshed entered in vertical bamboo flute barrel body, and then bass is more loud and clear when making to play wind instruments, sympathetic response is more abundant, effectively improves the effect of playing wind instruments.The utility model vibrational power flow is simple, reasonable.

Accompanying drawing explanation

Fig. 1 is one-piece construction schematic diagram of the present utility model;

Fig. 2 is the A place structure for amplifying schematic diagram of Fig. 1;

Fig. 3 is the plan structure schematic diagram of Fig. 1.

In Fig. 1 to Fig. 3:

1, vertical bamboo flute body; 11, upper pipe; 12, lower pipe; 2, mouthpiece; 3, arris; 4, thick bamboo tube; 5, tangent plane.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

A kind of vertical bamboo flute as shown in Figure 1, comprise vertical bamboo flute body 1, vertical bamboo flute body 1 adopts bamboo material to make, the top of vertical bamboo flute body 1 is provided with mouthpiece 2, mouthpiece 2 place is provided with arris 3, and the top of vertical bamboo flute body 1 is arranged with the thick bamboo tube 4 with mouthpiece 2 corresponding matching, specifically, the inwall of thick bamboo tube 4 and the outer wall close contacting fit of vertical bamboo flute body 1, and adopt adhesion agent to be bonded together between thick bamboo tube 4 and vertical bamboo flute body 1.The top of thick bamboo tube 4 is provided with the tangent plane 5 with arris 3 corresponding matching, the gradient of tangent plane 5 is equal with the gradient of arris 3, specifically, when mouthpiece 2 of the present utility model is in circumscribed crescent (as Tang Xiao), shown in Figure 1, this tangent plane 5 is positioned at same plane with inclined-plane, arris 3 place; When mouthpiece 2 of the present utility model is in interior " U " shape (as vertical bamboo flute and Nan Xiao), not shown, this tangent plane 5 is positioned at same curved surface with inclined-plane, arris 3 place.

The above forms agent structure of the present utility model.Compared with prior art, the utility model is by arranging said structure, increase effectively the wall thickness at mouthpiece 2 place, when making to blow, air-flow can be pressed darker, thus add the airshed entered in vertical bamboo flute body 1 body, and then bass is more loud and clear when making to play wind instruments, sympathetic response is more abundant, effectively improves the effect of playing wind instruments.The utility model vibrational power flow is simple, reasonable.

Play wind instruments effect to fully ensure, the upper surface of thick bamboo tube 4 is mutually concordant with the upper surface of vertical bamboo flute body 1.As a kind of preferred implementation, vertical bamboo flute body 1 comprises pipe 11 and lower pipe 12, and upper pipe 11 is detachably connected with lower pipe 12, the top of upper pipe 11 is provided with mouthpiece 2, by arranging said structure, the utility model being carried and stores more convenient, effectively improve the convenient degree of use.

The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
