Summary of the invention
It is sensitive that the technical problems to be solved in the utility model is that the brass instrument that uses this shop to chew can reach pronunciation, and the sound expansion capability is strong, and the sound tone color of high-low sound area is loose, natural, full, all plays easily in the broad range, tone color is also more consistent.
The technical solution that the utility model proposed is such: the double-layer tube that a kind of brass instrument is used number is chewed, comprise cup-shaped chewing, middle part is provided with the infundibulate cella in it, the described cup-shaped rearward end of chewing is provided with internal layer thin-walled conical catheter and the overcoat outer pillar on it, described cup-shaped rearward end and the internal layer thin-walled conical catheter leading section chewed adopts being fastenedly connected of removable or non-disconnectable formula, internal layer thin-walled conical catheter inner chamber and the perforation of described cella.Describedly cup-shapedly chew rearward end and internal layer thin-walled conical catheter leading section both can adopt integrated syndeton, also can adopt screw fastening structure.Described internal layer thin-walled conical catheter flare, outer pillar is cylindrical, and its leading portion wall thickness is also gradually thin to back segment, forms between internal layer thin-walled conical catheter and the outer pillar to contact at leading section and rearward end.Described internal layer thin-walled conical catheter leading section both can adopt wringing fit to be connected with outer pillar leading section, also can adopt the screw threads for fastening connection or weld fixedly connected.Described internal layer thin-walled conical catheter pipe thickness scope is 0.1-0.6mm.
Compared with prior art, the utlity model has following beneficial effect:
(1) because the conduit that double-layer tube number is chewed is to be formed by internal layer thin-walled conical catheter and outer pillar fit, inner conductor thickness only is 0.1-0.6mm (requiring the different thickness of design according to different tone colors), inside and outside conduit both ends join, and remainder forms a cavity.Because the tube wall of inner tube as thin as a wafer, when player's lips sent faint sound and air by inner tube, inner tube same-phase vibration at once increased loud amplitude and is sent in the brass instrument.
(2) because inner conductor vibrates easily, when playing this double-layer tube and number chew, feeling of the very first time is that its pronunciation is very sensitive.Number chew for some tradition and to be difficult to play or play effort, during fast as speed, that note is many, pitch is high and range is wide melody, if select for use this double-layer tube number to chew just to seem easily and light.Facts have proved,,, make the endurance prolongation of player's mouth strength so can just can obtain very strong volume with number chewing the strength of lacking than tradition because that double-layer tube number is chewed the sound expansion capability is strong and highly sensitive.This double-layer tube number is chewed when playing very weak sound, also is easy to tradition and number chews.
(3) because this shop chews and adopted the double-layer tube structure, so the sound that the sound tone color of its high-low sound area is all chewed for traditional number is loose, natural and full, and all play easily on the range of broad, its tone color is more consistent, and it is also consistent to play sensation.
(4), when design number is chewed,, just more easily reach desirable tone color as long as focus on the cup-shaped cella of chewing of design owing to adopt double-layer tube number to chew structure.
(5) the double-layer tube appearance of number chewing will be to improving brass instrument performance level, playing technique, and the physical demands and the mental burden that alleviate the player all can be very helpful.
Double-layer tube of the present utility model number is chewed on the brass instruments such as can being widely used in trumpet, trombone, large size, circular horn, althorn, tenor horn.
