CN203205019U - Bawu structure with wide range - Google Patents

Abstract

The utility model reveals a bawu structure with a wide range, which comprises a traditional sounding pipe and a traditional reed playing portion. The bawu structure with wide range is characterized in that: two hollowed finger-hole keys are disposed at the positions of finger-holes below a copper connection of a musical instrument, and the hollowed finger-hole keys are connected with two tune changing holes at the tail part of the musical instrument by a connection rod, thereby forming a ten-hole bawu. Compared with the traditional bawu structures, the bawu structure is additionally provided with two tune changing holes. The tune changing holes make notes of 4, 3 separately, thereby expanding the range of a buwu to: bass 3, 4, 5, 6, 7; alto 1, 2, 3, 4, 5, 6. The ten-hole bawu has two more notes than a traditional seven-hole bawu or eight-hole bawu, which enables convenient performance and wider range, and can be used for playing more Chinese and foreign famous music.

Description

A Wide Range Bau Structure

technical field

The utility model relates to the structural improvement of the national musical instrument bau. the

Background technique

Bawu is a bamboo-tube and brass-reed musical instrument with a tongue-shaped reed. It is a wind instrument of the Yi, Hani, Dai, Wa, Blang, Miao and other nationalities. It is called "Jifeilimo" in the local Yi language and "Meiba" in the Hani language. Bawu is a single-reed wind instrument popular in the Yi, Miao, and Hani ethnic groups in Southwest China. The Bawu is made of bamboo tubes, with eight finger holes (seven in the front and one in the back), and a tongue-shaped copper reed on the mouthpiece. When playing, the upper end is blown horizontally, and the vibrating reed makes a sound. The volume of Bau is small, but its timbre is soft. People in the Southwest call it a talking instrument. the

At present, most of the seven-hole and eight-hole Bau are used, and the range of the range is small, and only limited folk music can be played, which hinders the development of folk music. the

Utility model content

The technical problem to be solved by the utility model is to realize a Bawu structure with a wide range of sound range. the

In order to achieve the above object, the technical solution adopted by the utility model is: a wide-range Bawu structure, including the Bawu body, and the Bawu body is fixed with two connecting rods along the body through the connecting rod frame, and one end of the connecting rod Both are fixed with finger keys, and the finger keys are located between the spring tongue and the sound hole, and the other ends of the connecting rods are fixed with sound changing hole plugs, and the sound change hole plugs block the Bawu body respectively Two sound changing holes at the tail end, a torsion spring to keep the sound changing hole plugging piece open is installed between the connecting rod frame and the connecting rod. the

The said finger key is a ring structure. the

The diameter of the two sound changing holes is 1cm. the

The distances between the two sound changing holes are 1cm and 2cm from the end of the bau. the

The utility model adds two sound-changing holes on the basis of the traditional Bawu finger hole, which can emit two tones of 4 and 3 respectively, so that the scale of Bawu can be extended to bass 3, 4, 5, 6, 7, and middle tone 1 , 2, 3, 4, 5, 6, the ten-hole bau adds 2 tones, compared with the traditional seven-hole and eight-hole bau, it is more convenient to play, and can make the traditional bau wider range, thus playing more Chinese and foreign Famous song. the

Description of drawings

The following is a brief description of the content expressed in each accompanying drawing in the specification sheet of the utility model and the marks in the figure:

Fig. 1 is the schematic diagram of Bawu structure;

Fig. 2 is the structural representation of connecting rod, finger key and connecting rod shown in Fig. 1;

The marks in the above-mentioned figures are: 1, reed tongue; 2, finger key; 3, sound hole; 4, connecting rod frame; the

Detailed ways

Referring to Figures 1 and 2, it can be seen that the wide-range Bawu structure includes the Bawu body. The front end of the Bawu body is provided with a reed tongue 1 and a mouthpiece. There is a row of sound holes 3 in the middle, and two sound holes 3 are arranged at the tail. The sound changing hole 6 is also provided with two connecting rods 5 along the Bawu body, and each connecting rod 5 is fixed on the Bawu body by the connecting rod frame 5, and each connecting rod 5 one ends are all fixed with finger keys 2, and the fingers The key 2 is located side by side between the reed tongue 1 and the sound hole 3. The finger key 2 is a ring-shaped hollow structure. The other end of each connecting rod 5 is fixed with a sound changing hole plug 7. Parts 7 are respectively used to block the two sound changing holes 6 at the tail end of the Bau body, and a torsion spring to keep the sound changing hole blocking parts 7 open is installed between each connecting rod 5 and the connecting rod frame 4, so that pressing the finger key 2 then can realize that corresponding sound changing hole 6 is blocked by sound changing hole blocking piece 7, to increase Bau's range, unclamp finger key 2, then sound changing hole blocking piece 7 is subjected to torsion spring elastic force, keeps sound changing hole 6 opening state. the

In order to ensure the sound quality, the diameter of the two sound-changing holes 6 is 1cm, and the two sound-changing holes 6 are respectively hollow and the distance from the end of Bawu is 1cm and 2cm. the

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various insubstantial improvements are carried out by adopting the method concept and technical solutions of the present invention, or without Improvements that directly apply the concept and technical solutions of the present invention to other occasions are within the protection scope of the present utility model. the
