Abstract

A C-tune drop tuba with four sub-tuning tubes comprises a mouth sub-tube, a tuning device and an amplifying tube. The tuning device comprises first to fourth sub-tuning tubes, a main turning tube and four tuning buttons. The four tuning buttons are respectively arranged on corresponding sub-tuning tubes; the first sub-tuning tube is communicated with the mouth sub-tube; the fourth sub-tuning tube is communicated with the amplifying tube through the main turning tube; all sub-tuning tubes are mutually connected by supporting; the internal diameters gradually become increased from the first to the fourth sub-tuning tubes. The utility model provides the C-tune drop tuba with four sub-tuning tubes, the internal diameters of the four sub-tuning tubes gradually become increased, the tone quality becomes rich and mellow, and thereby the play effect can be raised. In addition, the integral structure of the C-tune drop tuba with four sub-tuning tubes is not changed, only internal diameters of the sub-tuning tubes are slightly adjusted, thereby the prior production technology and apparatus can be employed for production, and the cost of a production enterprise is not increased.

Description

A kind of C flat that has four branch pitch pipes is embraced greatly number

Technical field

The utility model belongs to the musical instrument manufacture technology field, particularly relates to a kind of C flat that has four branch pitch pipes and embraces greatly number.

Background technology

Embrace number; Have another name called bass saxhorn; Tone color is perfectly round abundant, is blowing instrument commonly used in a kind of band, is is mainly connected and composed by mouthpiece pipe, tuning device and amplifying tube; Wherein tuning device comprises a plurality of pitch pipes that are connected with each other and is installed in the tuning button on each pitch pipe, and the air-flow that can make in the corresponding pitch pipe through opening or closing of tuning button produces different musical notes.But the internal diameter that pitch pipe is gone up in the C flat number of embracing that has four branch pitch pipes commonly used at present is 19mm, and the tone color that therefore produces is not fine.

Summary of the invention

In order to address the above problem, the purpose of the utility model is to provide a kind of C flat that has four branch pitch pipes that can produce better tone color to embrace greatly number.

In order to achieve the above object; The C flat that has four branch pitch pipes that the utility model provides is connected and composed by mouthpiece pipe, tuning device and amplifying tube for big armful number; Wherein tuning device comprises the first fen pitch pipe that is connected with each other, second fen pitch pipe, the 3rd fen pitch pipe, the 4th minute pitch pipe, keynote pipe and four tuning buttons; Four tuning buttons are installed in respectively on the corresponding branch pitch pipe, and to control the air-flow in this minute pitch pipe, pitch pipe was connected with the mouthpiece pipe in first minute; Pitch pipe was connected with amplifying tube through the keynote pipe in the 4th minute, support and connection each other between each minute pitch pipe; The internal diameter of described first minute pitch pipe, second fen pitch pipe, the 3rd fen pitch pipe and the 4th fen pitch pipe increases gradually.

The internal diameter of described first minute pitch pipe, second fen pitch pipe, the 3rd fen pitch pipe and the 4th fen pitch pipe increases to 20mm gradually from 18.9mm.

It number is to adopt the method that four branch pitch pipe internal diameters on it are strengthened gradually to make its tone color perfectly round more abundant that the C flat that has four branch pitch pipes that the utility model provides is embraced greatly, therefore can improve playing effect.In addition; Because the utility model does not change the general structure that the former C flat that has four branch pitch pipes is embraced greatly number; Only with each minute the pitch pipe internal diameter slightly adjust, therefore still can adopt original production process and device to produce, so can not increase the cost of manufacturing enterprise.

Description of drawings

Fig. 1 embraces number structural representation greatly for the C flat that has four branch pitch pipes that the utility model provides.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the C flat that has four branch pitch pipes that the utility model provides is elaborated for big armful number.

As shown in Figure 1; The C flat that has four branch pitch pipes that the utility model provides is connected and composed by mouthpiece pipe 1, tuning device and amplifying tube 8 for big armful number; Wherein tuning device comprises first fen pitch pipe being connected with each other 3, second fen pitch pipe 4, the 3rd fen pitch pipe 5, the 4th minute pitch pipe 6, keynote pipe 2 and four tuning buttons 7; Four tuning buttons 7 are installed in respectively on the corresponding branch pitch pipe 3-6, and to control the air-flow in this minute pitch pipe, pitch pipe 3 was connected with mouthpiece pipe 1 in first minute; Pitch pipe 6 was connected with amplifying tube 8 through keynote pipe 2 in the 4th minute, support and connection each other between each minute pitch pipe; The internal diameter of described first minute pitch pipe 3, second fen pitch pipe 4, the 3rd fen pitch pipe 5 and the 4th fen pitch pipe 6 increases gradually.

The internal diameter of described first minute pitch pipe 3, second fen pitch pipe 4, the 3rd fen pitch pipe 5 and the 4th fen pitch pipe 6 increases to 20mm gradually from 18.9mm.

The C flat that has four branch pitch pipes that the utility model provides is embraced greatly and number is blown respond wellly through player's examination, and it is number perfectly round more abundant that the existing C flat with isometrical pitch pipe of tone color is embraced greatly, therefore improved the quality of product.
