Abstract

The utility model provides a frequency-modulation Chinese bamboo flute, belonging to the technical field of the traditional ethnic musical instrument. The frequency-modulation Chinese bamboo flute is composed of a flute head and a flute body. A flute brain is arranged in the flute head, one end of the flute head is enchased with an outer copper bush and an inner copper bush, a blowing hole is arranged between the flute brain and the flute head enchased with the outer copper bush and the inner copper bush, and one end of the flute body corresponding to the end of the flute head is also enchased with an outer copper bush and a projecting inner copper bush. The flute brain is arranged in the inner copper bush of the flute head, a through hole is arranged on the place of the inner copper bush of the flute head which is corresponding to the blowing hole, a sound-modulation opening is arranged on the projecting portion of the inner copper bush of the flute body, and the projecting portion of the inner copper bush of the flute body is inserted into the inner copper bush of the flute head, entering the clearance of the flute brain inner wall and the flute head inner wall. The frequency-modulation Chinese bamboo flute solves the fine modulation of the frequency or big variation by modulating the position of the blowing hole on the premise that the inner tube diameter of the Chinese bamboo flute is not changed, and the relationship between the pitch interval and the octave is not affected. The frequency-modulation Chinese bamboo flute solves the problem that the pitch of speech sound produced by the traditional Chinese bamboo flute influenced by temperature change is adverse to the tutti of the national music ensemble with uniform melody system.

Description

Frequency-regulation bamboo flute

Technical field

The utility model relates to a kind of horizontal national musical instruments-bamboo flute that blows, particularly relate to and a kind ofly can adjust the frequency-regulation bamboo flute that tone is restrained frequently, it is improvement to existing bamboo flute structure, especially to having replenishing of bamboo flute kind now, belong to traditional national musical instruments technical field, the person uses under different temperature conditions to be suitable for the bamboo flute playing.

Background technology

Chinese bamboo flute be a kind of be the traditional national musical instrument that raw material is made and had long history with natural bamboo, sound is dulect very popular when playing wind instruments, and has now become indispensable national musical instruments in the Chinese national orchestra.But owing to be subjected to physical environment and variation of temperature, its pitch can change.Therefore the player has to prepare several the bamboo flutes that tonality is identical in national orchestra, in order to using under the situation of Various Seasonal temperature variation, has brought many inconvenience to the player.In order to solve this difficult problem, people have carried out continuous research and have groped, tentatively made a kind of bamboo flute that can tuning, this bamboo flute utilization changes the length of flute body and adjusts the height that musical instrument pronounces, be about to flute and be divided into flute head and flute body two joints, flexibly connect with copper sheathing between flute head and the flute body, wherein an end of flute head studs with the interior copper sheathing of outer copper sheathing and protrusion, and corresponding flute body one end also studs with outer copper sheathing and interior copper sheathing.The interior copper sheathing of the protrusion on the first end of flute inserts in the interior copper sheathing of corresponding flute body one end and goes at ordinary times, during use, the player can pull out the flute body as required at any time, though can solve the part change in pitch to a certain extent, but also bring the true negative effect of octave cacoepy simultaneously, therefore numerous professional players need for guaranteeing to play, and the flute of difference satisfies need of work to have to still to take to use several same tone to restrain slightly frequently.How solving because influence of temperature change bamboo flute change in pitch makes bamboo flute can adjust the influence that produces because of difference variation, can guarantee pronunciation again accurately, is that the puzzlement Chinese bamboo flute is made the boundary and played the great difficult problem on boundary.

The utility model content

The purpose of this utility model is to overcome the prior art above shortcomings, improve by research, provide and a kind ofly can adjust the frequency-regulation bamboo flute that tone is restrained frequently, this frequency-regulation bamboo flute can utilize adjusts the position of blowing the hole, under the prerequisite that does not change caliber in the bamboo flute, solve fine setting of rule frequently or big change, and do not influence interval and octave relation, the whole musical instrument characteristics and the playing mode that not only have original traditional bamboo flute and possessed, but also solved traditional bamboo flute because the change in pitch that produced by temperature variation is unfavorable for a difficult problem of instrumental ensembling in the national orchestra of unified rule system.

The technical solution that the utility model provides is: this frequency-regulation bamboo flute is made up of flute head and flute body two parts, be provided with the flute brain in the flute head, one end of flute head studs with outer copper sheathing and interior copper sheathing, at the flute brain with in studding with, be provided with between the first end of the flute of outer copper sheathing and blow the hole, also stud with the interior copper sheathing of outer copper sheathing and protrusion on corresponding flute body one end, be characterized in that the flute brain is installed in the interior copper sheathing of flute head, and copper sheathing is provided with through hole with blowing on the corresponding position, hole in the flute head, the protrusion of copper sheathing partly is provided with a tuning opening in the flute body, in the flute body protrusion of copper sheathing partly insert the interior copper sheathing of flute head and enter the flute brain and the gap of flute head inwall in, the tuning opening of the protrusion that makes copper sheathing in the flute body on partly aimed at the hole of blowing on the flute head.Because the internal diameter circularity that the interior copper sheathing of lengthening makes the flute head blow Kong Zhidi body part reaches unified and standard, make pronunciation more accurately smooth.After flute body and flute head plug together, flute brain front end (by blowing an end in hole) can enter in the flute body copper sheathing a little, guaranteed that in adjustment process big variation does not take place the caliber that blows the position, hole, thereby guaranteed that pronunciation is accurately.The player utilizes and adjusts the position of blowing the hole according to the extraction distance of the concrete condition control interpolation copper sheathing of playing, and solves fine setting of rule frequently or big change under the prerequisite that does not change caliber in the bamboo flute, and does not influence interval and octave relation.

Compared with prior art, the beneficial effects of the utility model are: rational in infrastructure, make simple, utilize and adjust the position of blowing the hole, under the prerequisite that does not change caliber in the bamboo flute, solve fine setting of rule frequently or big change, and do not influence interval and octave relation, the whole musical instrument characteristics and the playing mode that not only have original traditional bamboo flute and possessed, but also solved traditional bamboo flute because the change in pitch that produced by temperature variation, be unfavorable for a difficult problem of instrumental ensembling, succession, development and perfect ancient these national musical instruments of Chinese bamboo flute in the national orchestra of unified rule system.
