Description

Dizi structure

This creation is about the structure of a wind instrument, especially the aboriginal flute structure.

Press, the head hunting flute (pgagu) is a traditional bamboo flute instrument of the aborigines. It is about 30 cm long. It has 3 to 4 press holes on the front and sound holes on the back. The mouthpiece blow holes are slit along the inner edge of the flute. Make an oblique angle with the vent hole on the back to make the sound easier.

Limited by the early production technology, the headhunting flute has only 3 to 4 press holes, which can present fewer tones, and the sound hole of the headhunting flute is set on the back, which is not conducive to the modern way of playing when using a microphone. , So the traditional headhunting flute still has room for improvement.

In view of this, how to eliminate the above-mentioned shortcomings is the technical difficulty that the creator of this case wants to solve; yes, based on years of experience in the relevant industry, the creator of this case, after years of painstaking research, trial and improvement, finally Successfully researched and developed this case and gave birth to the new model to enhance its efficacy.

In view of the above-mentioned shortcomings, the novel flute structure includes: a hollow tube body with a first opening and a second opening at both ends, and the top surface of the tube body is provided with a vertical portion and an inclined surface. The inclined surface is provided with a sound outlet, one end of the sound outlet is located at the bottom of the vertical part, the tube body has a wall inside, and the wall body is provided with an air hole corresponding to the sound outlet. A first finger hole, a second finger hole, a third finger hole, a fourth finger hole and a fifth finger hole are arranged on the upper space, and there is a predetermined distance between the first finger hole and the sound outlet. The first finger hole, the second finger hole, the third finger hole, and the fourth finger hole are located on the same axis as the sound outlet, and a sixth finger hole is provided on the bottom surface of the tube.

In order to facilitate the description of the content and the effects that can be achieved, the specific embodiments are listed in conjunction with the drawings. Please refer to the first and second figures. The structure of the new flute includes:

A hollow tube body 10. In this embodiment, the tube body 10 is made of bamboo, and the knot plates inside the bamboo are removed and polished to form a hollow tube body 10.

Both ends of the pipe body 10 have a first opening 11 and a second opening 12 respectively. The top surface of the pipe body 10 is provided with a vertical portion 13 and an inclined surface portion 14. The inclined surface portion 14 is provided with a sound outlet 141. One end of the sound outlet 141 is located at the bottom of the vertical portion 13.

Please refer to the second figure, the tube body 10 has a wall 15 inside, and the wall 15 is provided with an air hole 151 corresponding to the sound outlet 141, wherein the width of the air hole 151 is equal to the width of the sound outlet 141 .

The inclined portion 14 has a first predetermined angle, and the air hole 151 has a second predetermined angle, and the first predetermined angle is equal to the second predetermined angle.

The inclined portion 14 has a branch portion 142, the branch portion 142 is adjacent to one end of the sound outlet 141, and the branch portion 142 is opposite to the air hole 151. The inclined portion 14 has a wide side 143 and a narrow side 144. The wide side 143 corresponds to the bottom of the vertical portion 13, and the wide side 143 to the narrow side 144 are tapered.

The tube body 10 is provided with a first finger hole 101, a second finger hole 102, a third finger hole 103, a fourth finger hole 104, and a fifth finger hole 105 at intervals. There is a predetermined distance between the sound outlet 141, which serves as a resonance cavity. The first finger hole 101, the second finger hole 102, the third finger hole 103, and the fourth finger hole 104 are located with the sound outlet 141. On the same axis, the bottom surface of the tube body is provided with a sixth finger hole 106, and the sixth finger hole 106 is located between the sound outlet 141 and the first finger hole 101.

Please refer to the second figure. When the user blows, he blows from the first opening 11, and the air flows through the air hole 151 to the sound outlet 141 and impacts the splitting portion 142. Since the top surface of the splitting portion 142 is the inclined surface 14, Therefore, the airflow can be divided into two, so that the airflow can flow outward and inward stably, and then resonate and produce sound.

In this embodiment, the tube body 10 is provided with a plurality of ring bodies 20 at intervals.

Please refer to the third figure, the novel flute structure includes long and piccolo shapes. In this embodiment, the fifth finger hole 105 is located on one side of the tube body, so as to facilitate the user's little finger to press the The fifth finger hole 105.

The above detailed description is a specific description of one of the possible embodiments of the present model, but the embodiments are not intended to limit the scope of the patent of the present model. Any equivalent implementation or modification that does not deviate from the technical spirit of the present model shall be included in this case. In the scope of the patent.
