Description

Flute air blowing mouth structure

【Technical field】

The utility model is related to a kind of flute air blowing mouth structure, and espespecially inflatable mouth enters internal a bit of by body exterior Distance has an air inlet internal orifice, and air inlet internal orifice internal diameter is small compared with inflatable mouth internal diameter, and one turn is formed between inflatable mouth and air inlet internal orifice The flute air blowing mouth structure of folding area.

【Background technology】

Flute is Chinese Traditional Instruments, and the sound for playing wind instruments flute shows that tone is simple and honest mellow and full, soft and graceful smooth melodious sound Sound, deep to be liked by the general common people and hobby music personage, flute is played wind instruments and is also applied to folk music, opera, national music ensemble, friendship Mixing is used in ringing philharmonic society and contemporary music, from that can produce distinguished mixing musical note, makes hearer intoxicated, is in a cheerful frame of mind.

As shown in figure 1, the inflatable mouth floor map of tradition Tao Di, mainly a main body 10, main body 10 has a plurality of sounds Hole 11, an air cavity 12 and an inflatable mouth 13, inflatable mouth 13 are blown into gas for the mouth of human body, and sound hole 11 is pressed for finger, adjusts sound Rate is used, and air cavity 12 is inside main body 10, to accommodate and merge gas, then produces the different sound rate of height by the outlet of sound hole 11, Inflatable mouth 13 is sensible always to air cavity 12 and sound hole 11, and inflatable mouth 13 is usually straight endoporus 131 from outside to inside.

It is the inflatable mouth floor map of traditional Tao Di shown in Fig. 2, main body 20 reduces inflatable mouth 23 gradually from outside to inside The endoporus 231 of internal diameter, endoporus 231 is sensible to air cavity and sound hole, and the endoporus 131 that the audio that this structure is played wind instruments is more straight is (as schemed 1) audio played wind instruments is good, is to collect the air-flow of institute bassoonist to be concentrated to air cavity and sound hole, more improves the clangor of audio Effect.

【Utility model content】

The inflatable mouth 13 of known traditional Tao Di is by inside outside flat mouth to air cavity 12, its caliber size is consistent, Tao Di Sounding smooth out, or inflatable mouth 23 by outside flat mouth to air cavity inside, its bore reduces gradually, and Tao Di sounding has clang sound effect Really, respectively have its advantage and disadvantage, but be insufficient for various bassoonists play wind instruments habit.

A kind of flute air blowing mouth structure of the utility model, its main purpose is：1st, it is tapered small interior different from traditional inflatable mouth Footpath to air cavity structure, this case can be in air-flow be integrated to certain air pressure in break over region, then following current is to air inlet internal orifice, makes flute sounding It is smooth, effectively without interrupt, speak it is loud and sonorous in soft and graceful gracefulness.2nd, rectangle, square, ellipse, circle be can be applied to Etc. variously-shaped inflatable mouth.3rd, can be in inflatable mouth height down's half, open height also reduces half in air inlet.

By the technical solution of the utility model, details are as follows below：

A kind of flute air blowing mouth structure, is a main body, and main body has predetermined body, inside there is an air cavity, and main body is provided with a plurality of Sound hole and an inflatable mouth, sound hole are distributed in main body precalculated position and sensible air cavity, and sound hole is pressed for finger, and adjustment sound rate is used, Air blowing affiant is blown into gas, inflatable mouth be it is sensible always to air cavity and sound hole, air cavity to accommodate and fusion gas, then by sound hole Outlet produces the different sound rate of height；

It is characterized in that：Inflatable mouth has an air inlet internal orifice, air inlet internal orifice internal diameter by body exterior into an internal segment distance It is smaller than inflatable mouth internal diameter, and a break over region is formed between inflatable mouth and air inlet internal orifice.

Wherein, inflatable mouth height down's half, open height also reduces half in air inlet.

Wherein, the inflatable mouth is rectangle hole.

Wherein, the inflatable mouth is square mouth.

Wherein, the inflatable mouth is oval port.

The beneficial effects of the utility model are：Different from traditional inflatable mouth gradually reduced inner diameter to air cavity structure, can in turn Air-flow is integrated in folding area to certain air pressure, then following current is to air inlet internal orifice, makes flute sounding smooth, effectively without interrupting, goes out sound pitch With soft and graceful gracefulness in high.Can be the variously-shaped inflatable mouths such as rectangle, square, ellipse, circle.Air blowing open height contracts Subtract half, open height also reduces half in air inlet.

【Specific embodiment】

A kind of flute air blowing mouth structure of the utility model, as in Figure 3-5, a mainly main body 30 is main for first embodiment Body 30 has predetermined body, and the utility model one embodiment of citing can be variously-shaped during actual fabrication, inside there is an air cavity 32, main Body 30 is provided with the inflatable mouth 33 of a plurality of sound holes 31 and, and sound hole 31 is distributed in the precalculated position of main body 30, sound hole 31 by main body 30 outside In the sensible air cavity 32 in portion, sound hole 31 is pressed for finger, and adjustment sound rate is used, and inflatable mouth 33 is rectangle hole, is blown into for human body mouth Gas, inflatable mouth 33 is sensible always to the sound hole 31 of air cavity 32 and, and air cavity 32 is inside main body 30, and to accommodate and merging gas Body, then high and low different sound rate is produced by the outlet of sound hole 31.

The utility model is characterized mainly in that：Inflatable mouth 33 is provided with one and enters by the outside of main body 30 into internal a small distance Gas internal orifice 34, the internal diameter of air inlet internal orifice 34 is small compared with the internal diameter of inflatable mouth 33, and one turn is formed between inflatable mouth 33 and air inlet internal orifice 34 Folding area 35, the interior angle of the break over region 35 can be perpendicular inside corner or radian interior angle.

From above-mentioned structure, a kind of flute air blowing mouth structure of the utility model, human body mouth is blown into gas in inflatable mouth 33, gas enters back into the air inlet internal orifice 34 of reduced inner diameter in break over region 35, the gas being so blown into the saturated pressure of break over region 35, Increase the flow velocity of gas when reentering air inlet internal orifice 34, gas enters air cavity 32 and sound hole 31, the sound rate for producing height different.

This case be different from traditional inflatable mouth gradually reduced inner diameter to air cavity structure, the tone that both tradition and this case are spoken is high Low to have nothing in common with each other, this case can be in integration air-flow in break over region 35 to certain air pressure, then following current is to air inlet internal orifice 34, makes flute sounding It is smooth, effectively without interrupting, speak it is loud and sonorous in soft and graceful gracefulness, be structure innovation that current flute inflatable mouth does not have.

The utility model second embodiment, as shown in fig. 6, by the inflatable mouth 43 of main body 40, implementing into inflatable mouth 43 for just Square orifice, inside still there is air inlet internal orifice 44, equally may achieve effect of above-described embodiment.

The utility model 3rd embodiment, is as shown in Figure 7 that, by the inflatable mouth 53 of main body 50, it is ellipse to implement into inflatable mouth 53 Circular port, inside still there is air inlet internal orifice 54, equally may achieve effect of above-described embodiment, and the utility model inflatable mouth is alternatively circle Or triangle mouthful etc. is variously-shaped.

The utility model fourth embodiment, the height down's half of inflatable mouth 63 of the main body 60 as shown in Figure 8, air inlet internal orifice 64 height also reduce half, also reach effect of above-described embodiment.
