Abstract

The utility model discloses a cucurbit flute assistant tone tube slide switch. The cucurbit flute assistant tone tube slide switch comprises a sleeve and a slide sleeving ring; the sleeve is arranged at the middle of an assistant tone tube, and two ends of the sleeve are fixedly connected with the assistant tone tube; the tail end of the assistant tone tube is sealed; a sound-exiting hole is formed on the side wall of the sleeve; and the slide sleeving ring is sleeved on the sleeve and can slide along the sleeve so as to open or close the sound-exiting hole. When playing a cucurbit flute, a performer only needs to shift the slide sleeving ring with his little finger which is not involved in cucurbit flute playing so as to open or close the sound-exiting hole on the assistant tone tube arbitrarily, and the operation quantity of the performer is small, and at the same time, the operation can be smooth; and it only needs to shift the slide sleeving ring to one direction until the slide sleeving ring cannot be moved, such that harmonic can be started or shut down, and misoperation can be avoided. The cucurbit flute assistant tone tube slide switch of the utility model is advantageous in simple structure, low manufacturing cost, convenient use and suitability for large-scale popularization.

Description

The secondary sound pipe of cucurbit flute slipping switch

Technical field

The utility model relates to the secondary sound pipe of a kind of cucurbit flute slipping switch.

Background technology

Cucurbit flute is the musical instrument of Minorities in Yunnan, and because its tone color is graceful, expressive force is abundant, deeply is subjected to liking of national people.The maximum characteristics of cucurbit flute are and can play harmony by secondary sound pipe.Traditional secondary sound pipe is included in secondary sound pipe afterbody and installs cork additional or leave the switch that sound hole is controlled secondary sound pipe harmony with secondary sound pipe tail end sealing and at sidewall.When playing, use cork to block the afterbody of secondary sound pipe, perhaps block sender with little finger of toe, at this moment in the secondary sound pipe owing to there is not the air-flow process, the reed of secondary sound pipe upper end just can not shake, the harmony of secondary sound pipe is in closed condition.If cork is extracted or unclamped pinkie, at this moment, air-flow can enter secondary sound pipe from the cucurbit upper end, and the reed vibrations by secondary sound pipe upper end, sends beautiful harmony.

In actual the performance, if employing is the secondary sound pipe of cork style, if the player needs to play harmony midway, can rapidly cork be pulled out, open auxiliary sound pipe is played harmony, play completely will close secondary sound pipe the time when harmony, must rapidly cork be inserted again the afterbody of secondary sound pipe.This process even if operation is consummate, also needs the regular hour, and action is larger during operation, notice that can dispersed audience, thus reduce the expressive force played and appeal even can have influence on the performance beat.Simultaneously, when playing, because the player is nervous, makes a fault possibly, even cork is lost, the difficult situation that appearance can not continue to play.And adopt sidewall to leave the secondary sound pipe of sound hole, so when not needing harmony, the player must pin sender on the secondary sound pipe for a long time with pinkie, must decontrol again when needing harmony, since cucurbit flute itself be exactly by player's fingering change to decontrol with idea or closed keynote pipe on sender send different sound, with regard to so that the player has increased operational ton, cause the fingering part stiff like this, improve the performance difficulty, be unfavorable for player's performance.

Summary of the invention

The secondary sound pipe of the cucurbit flute slipping switch that the unworkable technical matters of secondary sound pipe when playing in order to solve present cucurbit flute, the utility model provide a kind of player of convenience to operate.

In order to realize above-mentioned technical purpose, the technical solution of the utility model is, the secondary sound pipe of a kind of cucurbit flute slipping switch, comprise sleeve and slip lasso, described sleeve is arranged at secondary sound pipe middle part and two ends are fixedly connected with secondary sound pipe, the tail end sealing of secondary sound pipe has sender on the sidewall of sleeve, and described slip cap snare is on sleeve and can slide to open or close sender along sleeve.

The secondary sound pipe of described a kind of cucurbit flute slipping switch, the length of described sleeve is at least slip lasso length and sender diameter sum.

The secondary sound pipe of described a kind of cucurbit flute slipping switch, the external diameter of described slip lasso equates with the external diameter of secondary sound pipe.

Technique effect of the present utility model is, when playing, can open or close arbitrarily sender on the secondary sound pipe as long as arbitrarily stir the lasso that slides with little finger of toe, player's operational ton is very little, and the very convenient smoothness that operates simultaneously only needs the slip lasso is pushed and can not move to a direction, just can realize opening or closing harmony, maloperation can not occur, the utlity model has characteristics simple in structure, that cost of manufacture is low, easy to use, be suitable for large-scale promotion.

The utility model is described in further detail below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Wherein, 1 is that sleeve, 2 is that slip lasso, 3 is that secondary sound pipe, 4 is sender.

Embodiment

Referring to Fig. 1, the utility model comprises sleeve and slip lasso, and sleeve is arranged at secondary sound pipe middle part and two ends are fixedly connected with secondary sound pipe, the tail end sealing of secondary sound pipe, have sender on the sidewall of sleeve, the slip cap snare is on sleeve and can slide to open or close sender along sleeve.The length of sleeve is at least slip lasso length and sender diameter sum.The external diameter of slip lasso equates with the external diameter of secondary sound pipe.

When making, at first in place secondary sound pipe is cut off, then with the slip cap snare on sleeve, two ends with sleeve are fixedly connected with respectively the cut secondary sound pipe of two joints again, sleeve is fixedly the time, and the sender on the sleeve can towards the keynote pipe to keep overall appearance, can apply lubricant simultaneously as required on slip lasso inwall, when sliding, better operate guaranteeing, at last with the tail end sealing of secondary sound pipe.

During performance, play wind instruments harmony if need to open secondary sound pipe, then utilize near the little finger of toe without the task of performance of secondary sound pipe switch, expose sender with dialling on the slip lasso, this moment, secondary sound pipe was in opening, can play out harmony, if need to close harmony, then the slip lasso is set aside and closed sender and get final product.

Claims (3)

1. the secondary sound pipe of cucurbit flute slipping switch, it is characterized in that, comprise sleeve and slip lasso, described sleeve is arranged at secondary sound pipe middle part and two ends are fixedly connected with secondary sound pipe, the tail end sealing of secondary sound pipe, have sender on the sidewall of sleeve, described slip cap snare is on sleeve and can slide to open or close sender along sleeve.

2. the secondary sound pipe of a kind of cucurbit flute according to claim 1 slipping switch is characterized in that the length of described sleeve is at least slip lasso length and sender diameter sum.
