Abstract

The utility model relates to a tone-modifiable flute and particularly relates to a flute which can be subjected to tone modification conveniently during the process of playing. A slidable homogeneous sleeve is arranged at the external periphery of one end or the two ends of a flute body respectively; an anti-release structure is arranged between the flute body and the sleeve; and the sleeve keeps the internal periphery of the sleeve and the external periphery of the flute sealed while the sleeve can slide outside one end of the flute. When the tone modification is required during the process of flute playing, the sleeve(s) at the other end or the two ends is/are slid or contracted towards the outside or inside of the end(s) at a specific distance by using hands, the length that a playing air flow flows through the flute can be changed, meanwhile, the air flow is subjected to pressure change during the process of flowing through the sleeve part(s), the vibration frequency range of a flute diaphragm can be changed, and the tonal scale emitted when a player holds the same flute hole of the same flute is then changed, thereby achieving the aim that the flute can be subjected to tone modification or repeated tone modification conveniently.

Description

The flute that can modify tone

Technical field

The utility model relates to a kind of flute that can modify tone, and especially in playing procedure, can carry out the flute of tone changing easily.

Background technology

At present; Known flute is to be made up of a bamboo trunk or a metal tube with bore, when playing, plays wind instruments the flute hole, and air-flow is flowed out to two ends in the flute pipe; Shake bamboo membrane simultaneously and sound, send the music of different syllables in the flute hole that press...withes one's finger different through the player.But; Because length and the bore of flute are fixed, the frequency range that air-flow promotes the bamboo membrane vibration is limited, so the processing that in playing procedure, can not modify tone of general flute; Modify tone if desired; Just must change an other flute or, make playing procedure complicated, and error makes mistakes easily by another one people performance.

The utility model content

In order to overcome the deficiency that existing flute can not modify tone when playing, the utility model provides a kind of flute that can modify tone, and this flute can not only be played as common flute, and can easily in playing procedure, modify tone.

The utility model solves the technical scheme that its technical matters adopted: the utility model comprises:

A flute body;

At least one sleeve is arranged on the end of flute body;

At least one disconnecting prevention structure, said sleeve utilize this disconnecting prevention structure to be sheathed on said flute body.

Wherein, the two ends of said flute body respectively are provided with a sleeve.

Wherein, the internal diameter of said sleeve pipe is slightly larger than the external diameter of said flute body, and sleeve pipe keeps in the sleeve pipe sealing of week and flute periphery, unlikely gas leakage when can sliding in an end outside of flute.

Wherein, said sleeve inboard is provided with several described thrust recesses.

Wherein, said disconnecting prevention structure is the thrust ball, and said sleeve inboard is provided with the thrust recess that supplies thrust ball location, and several these thrust recesses are located in the sleeve chute.

Wherein, said flute body and said sleeve are identical material.

When the player is playing wind instruments in the flute process when needing to modify tone; The sleeve pipe at the other end or two ends is slided outside the termination or shrink particular distance with hand; The length of the airflow passes flute of playing wind instruments is changed, and the pressure variation takes place in air-flow when flowing through sleeve portion simultaneously, makes the vibration frequency range of bamboo membrane change; Thereby change has taken place in the scale that when the player pins the same flute hole of same flute, sends, and is able to the purpose that modifies tone easily or repeatedly modify tone.

The beneficial effect of the utility model is: can when the player play wind instruments flute, modify tone easily or repeatedly modify tone and handle, need not change flute or another one people and play, the result is simple, convenient enforcement.

Description of drawings

Fig. 2 is the structural map of second embodiment of flute that can modify tone.

[main element symbol description]

1 flute body, 2,3 sleeves

4 thrust balls, 5 sleeve chutes

6 thrusts are recessed.

Embodiment

One embodiment of the utility model is as shown in Figure 1; Flute body 1, sleeve 2, sleeve 3, disconnecting prevention structure are installed together; This disconnecting prevention structure can be the common disconnecting prevention structure that concavo-convex edge cooperates, and is thrust ball 4 and present embodiment adopts, and flute body 1 is made with sleeve 2,3 preferable employing identical material.

Sleeve 2 is installed in an end of flute body 1; Sleeve 3 is installed in the other end of flute body 1; Sleeve pipe 2 and 3 internal diameter are slightly larger than the external diameter of said flute body 1; Thrust ball 4 is installed in the two ends of flute body 1 respectively, and the thrust recess 6 that supplies thrust ball 4 location is offered in the inboard relevant position of sleeve 2 and sleeve 3 simultaneously, and is arranged in the sleeve chute 5 at several these thrust recesses 6.

Sleeve chute 5 always slides sleeve 2 or 3 along thrust ball 4, and not relatively flute body 1 rotate.

Another embodiment of the utility model is as shown in Figure 2, flute body 1, sleeve 2, disconnecting prevention structure is installed together, and the preferable thrust ball 4 of selecting for use of disconnecting prevention structure, flute body 1 is made with sleeve 2 preferable employing identical material.Sleeve 2 is installed in an end of flute body 1, the internal diameter of sleeve pipe 2 is slightly larger than the external diameter of said flute body 1, and thrust ball 4 is installed in the end that flute body 1 is provided with sleeve 2.The thrust recess 6 that supplies thrust ball 4 location is offered in the inboard relevant position of sleeve 2 simultaneously, and in these thrust recess 6 set inside sleeve chute 5 is arranged.Be convenient to the player and in the process of playing wind instruments, carry out one or many modified tone operation in the quiescent interval of pinning the flute hole.

The tone that modifies tone is as required confirmed the position of two ends sleeve and the length of slip, and the cooperation of thrust recess that can also be through utilizing thrust ball and diverse location produces different sliding distances, and realization is modified tone repeatedly.
