The present invention relates to a flute having a straight tube and a mouthpiece having a plurality of keys for changing the pitch, and the mouthpiece is provided with a mouthpiece, the mouthpiece being The body tube with the keys is engaged.

Traditionally, the flute pipe of the flute is directly engaged with the flute body with the keys. Since the tone blown by the flute must be within a defined, precisely defined frequency range, the flute mouthpiece must be played and played. The distance between the keys that act to change the pitch is large. For a person who generally has an adult flute player's height, this distance can be matched by the proper posture of the flute player's arm. They don't have to play the instrument with a posture that would hinder the operation of the fingers and cause fatigue, and their heads don't have to be placed in an unnatural, fatigue-prone posture. For flute players whose body conditions are not able to meet the above conditions, especially for children, the large distance between the mouthpiece and the keys that must be actuated to change the pitch will have various disadvantages. Excessively stretched arms can impede finger flexibility and tend to cause tension and stiffness in the shoulders and spine, which can affect the results of practice and learning on the one hand, and bone damage on the other. In order to shorten the distance between the mouthpiece and the plurality of keys for changing the pitch, it has been proposed to bend the mouthpiece by 180 degrees so that the mouthpiece is greatly separated from the geometric axis of the body of the flute with the key, so that The player can't hold the instrument stably, and it is difficult to learn the sound that affects the flute. At the same time, when learning a flute, he learns that a mouth blows a straight mouth and does not use the finger movement, and the blow has a straight blow tube. In the case of the flute, sometimes the player has to work hard to change the habit of matching in order to achieve this finger movement.

It is an object of the present invention to provide a flute that solves the above problems.

The flute of the present invention has a mouthpiece tube and a body tube, wherein the mouthpiece tube faces a side of the body tube provided with the key, forming a curved section of the sound tube, and the curved section is provided One end of the body of the key is aligned with the geometrical axis of the curved section toward the geometrical axis of the other end of the mouthpiece. After the end of the curved section is connected to the mouthpiece tube, and the other end is connected to the body tube of the sound tube with the key, the geometric axes of the body tube of the mouthpiece and the sound tube with the key are also aligned with each other. Through this combination, the above purpose can be achieved. In this way, in the case of retaining the preset frequency position of the flute pronunciation, the selection of the shape of the shape and the selection of the size of the arc segment of the sound tube can be used to preset the mouthpiece and the pitch for changing the pitch. The distance between the keys, so that the flute can be played in a normal arm position without twisting the shoulders and vertebrae. Through the structure of the present invention, the flute can be maintained in a stable posture during performance, so that the finger is not stiff in order to hold the flute in a certain posture, and can also be maintained in order to blow out the correct tone. The steady state of the air blows against the mouthpiece. This blow angle stabilization feature helps you learn how to affect the sound. There is also a special advantage. By easily replacing the curved section of the sound tube, you can change the distance between the mouthpiece and the keys used to change the pitch, thereby adjusting the instrument to match the growth of the child playing the flute. Height changes.

A preferred embodiment of the flute of the present invention, as well as an architecturally and audibly audible embodiment, is characterized in that the acoustic tube arc segment is the first extending from the mouthpiece tube and extending along the geometric axis of the mouthpiece tube. The end zone begins to bend outwardly, then bends in the opposite direction, and then transitions again from this reverse bend to the second end zone, which is along the body tube with the key on the sound tube. Extend the geometry axis and connect the tube.
