Abstract

The utility model relates to a children trombone with smooth playing airflow. The children trombone comprises a U-shaped sleeve, an air-intake variable tone sliding tube, an air-outlet variable tone sliding tube, an inner tube, the main tuning tube and a bell mouth bassoon, wherein the air-intake variable tone sliding tube and the air-outlet variable tone sliding tube form sliding fit with the U-shaped sleeve. The children trombone is characterized in that an inner circular arc of the main tuning tube is formed by a first arc whose radius is 62mm-63mm and a second arc whose radius is 40mm-41mm from an air inlet pipe end, wherein the first arc forms anastomosis with the second arc. The trombone has the following advantages that: aiming at a child body characteristic and a playing style, a radian of the air inlet pipe end of the main tuning tube is adjusted so as to form a slow rising mode of the airflow from low to high; efforts can be saved when a musician is playing and the airflow is smooth; accuracy of children trombone timbre is guaranteed.

Description

Play wind instruments children's trombone of airflow smooth

Technical field

The utility model belongs to wind instrument, relates in particular to a kind of children's trombone of playing wind instruments airflow smooth.

Background technology

Children's trombone is formed by number mouth, U molded cannula and with the air inlet that the U molded cannula is slidingly matched change voice slip pipe, lining pipe, keynote pipe and the hydraucone bassoon of slip pipe and giving vent to anger of changing voice.It is mainly by air inlet the change voice slip pipe and the flexible pitch that decides of slip pipe of changing voice of giving vent to anger.The player need be through the length of the slip pipe number of change body and the pitch of fundamental tone.The musician will be familiar with and grasp the relation of the flow and the flow velocity of required air-flow when playing wind instruments just strong and weak different sounds.Learn that thus the body of children's trombone is the key that airflow smooth is played wind instruments in decision.And the inner arc radius of the keynote pipe that the hydraucone bassoon is pegged graft be by two sections radiuses be the circular arc of 42mm and wherein between radius constitute the U font for the 62mm circular arc.Children in the process of playing wind instruments since strength a little less than, air communication is not too smooth and easy when crossing U font keynote pipe, the player needs higher skill control tolerance to guarantee the accuracy of tonequality, otherwise can influence performing effect.

The utility model content

The purpose of the utility model is to overcome the deficiency of above-mentioned technology; And a kind of children's trombone of playing wind instruments airflow smooth is provided; Adjustment keynote pipe is gone into the radian of tracheae end, forms air-flow by hanging down to the high slow mode that rises, and the musician is more laborsaving when playing wind instruments; Airflow smooth has guaranteed the accuracy of children's trombone tonequality.

The utility model is for realizing above-mentioned purpose; Adopt following technical scheme: a kind of children's trombone of playing wind instruments airflow smooth; The air inlet that comprises the U molded cannula and be slidingly matched with the U molded cannula the change voice slip pipe and slip pipe, lining pipe, keynote pipe and the hydraucone bassoon of changing voice of giving vent to anger is characterized in that: circular arc is that 62mm-63mm first circular arc and another section radius are that the 40mm-41mm second circular arc kissing connects and constitutes from going into the tracheae end by one section radius in the said keynote pipe.

Beneficial effect: to child's torso characteristics and playing style, adjustment keynote pipe is gone into the radian of tracheae end, and the musician is more laborsaving when playing wind instruments to the high slow mode that rises by low to form air-flow, and airflow smooth has guaranteed the accuracy of children's trombone tonequality.

Embodiment

Embodiment below in conjunction with accompanying drawing and preferred embodiment detailed description the utility model.As shown in the figure; A kind of children's trombone of playing wind instruments airflow smooth; Comprise U molded cannula 1 and with the air inlet that the U molded cannula is slidingly matched change voice slip pipe 2 with give vent to anger change voice that slip pipe 3, lining manage 4, keynote pipe 5 and hydraucone bassoon 6, circular arc is that the 62mm-63mm first circular arc 5-1 and another section radius are that the 40mm-41mm second circular arc 5-2 kissing connects and constitutes from going into the tracheae end by one section radius in the said keynote pipe.

Principle of work:

Circular arc is connect by first circular arc and second circular arc kiss and forms air-flow by hanging down to the high slow mode that rises from going into the tracheae end in the keynote pipe; Improve with the change voice caliber of slip pipe 3 of giving vent to anger in conjunction with the air inlet that is slidingly matched with the U molded cannula slip pipe 2 of changing voice; The musician is more laborsaving when playing wind instruments; Airflow smooth has guaranteed the accuracy of children's trombone tonequality.

The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.

Claims

1. children's trombone of playing wind instruments airflow smooth; The air inlet that comprises the U molded cannula and be slidingly matched with the U molded cannula the change voice slip pipe and slip pipe, lining pipe, keynote pipe and the hydraucone bassoon of changing voice of giving vent to anger is characterized in that: circular arc is that 62mm-63mm first circular arc and another section radius are that the 40mm-41mm second circular arc kissing connects and constitutes from going into the tracheae end by one section radius in the said keynote pipe.
