As shown in fig. 1-3, an entire bamboo flute with adjustable sound comprises a flute pipe 1 with a cavity therein, wherein the flute pipe 1 is sequentially provided with a blowing hole 11, a film sticking hole 12, a finger hole 13 and a sound outlet hole 14, and the entire bamboo flute with adjustable sound further comprises:

the tuning piece 2 is provided with a fixing plate 21 and a baffle plate 22 which are bent oppositely, the fixing plate 21 and the baffle plate 22 are made of sheet metal, the fixing plate 21 is connected to the flute pipe 1, the baffle plate 22 is matched with the inner wall of one end, close to the film sticking hole 12, of the blowing hole 11 and extends downwards into a cavity of the flute pipe 1 along the edge of the inner wall, and the baffle plate 22 is used for guiding the direction of air flow entering the cavity and adjusting the incident angle of the air flow;

and the limiting fixing piece 3 is arranged on the flute pipe 1 and used for limiting and fixing the fixing plate 21 and the flute pipe 1.

The fixing plate 21 may be a thin and long sheet metal plate, one end of the baffle plate 22 connected to the fixing plate 21 is integrally formed with the fixing plate 21, and the baffle plate 22 may be bent downward with respect to the fixing plate 21 by the extensibility of the metal plate.

Wherein, the bending angle between the fixed plate 21 and the baffle 22 is 0-90 degrees.

As a further preference, referring to fig. 4 to 7, the bending angle between the fixing plate 21 and the baffle plate 22 is set to 90 ° or 45 °.

Specifically, when the sound of playing the bamboo flute is too high, can adjust the angle of bending between fixed plate 21 and the baffle 22 to 90, baffle 22 and the hole 11 top of blowing become 90 vertical state promptly, the angle of the incident air current that gets into flute 1 cavity at this moment diminishes, the tone also diminishes thereupon, on the contrary, when the sound of playing the bamboo flute is too low, can adjust the angle of bending between fixed plate 21 and the baffle 22 to 45, baffle 22 and the hole 11 top of blowing become 45 oblique angle states promptly, the angle of the incident air current that gets into flute 1 cavity bone this moment grow, the tone also grows thereupon.

In order to make the baffle 21 extending into the flute cavity closely adhere to the inner wall of the blowing hole 11, the baffle 21 may be set to a shape adapted to the inner wall of the blowing hole 11 near the end of the film sticking hole 12, for example, the blowing hole 11 is set to a circular hole, the baffle 21 may be set to an arc shape adapted to the circular hole wall, the arc length of the baffle 21 may be set to 1/2 slightly smaller than the circumference of the blowing hole 11, and specifically, the baffle 21 may be designed according to the size and shape of the blowing hole 11, so that the baffle 21 is not only convenient to bend, but also can ensure that the baffle 21 can guide the airflow.

Wherein, the limiting fixing member 3 can be a transparent adhesive tape, and the fixing plate 21 and the flute 1 are glued together through the transparent adhesive tape.

Of course, in order to make the tuning piece 2 connected to the flute pipe 1 more firmly, referring to fig. 3 to 9, the limit fixing piece 3 may include:

the threaded hole 15 is arranged on the surface of the flute pipe 1 and is positioned between the blowing hole 11 and the film sticking hole 12;

an adjusting groove 211 provided on the fixing plate 21 to correspond to the screw hole 15;

one end of the fastening member 31 passes through the adjusting slot 211 and the threaded hole 15 in sequence, and the other end is clamped above the fixing plate 21, so as to fixedly connect the fixing plate 21 and the flute pipe 1.

Wherein, fastener 31 can be established to the hexagon head bolt of one end and screw hole 15 looks adaptation, places tuning piece 2 on flute pipe 1 earlier and aligns adjustment tank 211 with screw hole 15 during the use, again with the bolt in adjustment tank 211 and screw hole 15 of screwing in proper order in, can be with fixed plate 21 and flute pipe 1 fixed connection.

Further, in order to facilitate manual screwing of the bolt, the fastener 31 may be a claw-type bolt.

The working principle of the embodiment is as follows:

before playing, the player can manually bend the damper 22 to a proper angle, and then mount the tuning piece 2 on the flute pipe 1. Certainly, in order to conveniently and accurately adjust the bending angle of the baffle 22, the tuning piece 2 may be installed on the flute pipe 1, and then the baffle 22 is pressed towards the direction close to the fixing plate 21 by a knife or a pen holder or other slender objects, so as to reduce the bending angle between the baffle 22 and the fixing plate 21, increase the incident angle of the airflow, and increase the tone of the bamboo flute; or the fixing plate 21 is moved towards the film sticking hole 12 along the axial direction of the flute pipe 1, at this time, the inner wall of the blowing hole 11 can push the baffle plate 22 out towards the direction far away from the fixing plate 21, the bending angle between the baffle plate 22 and the fixing plate 21 is adjusted to be large, the incident angle of the air flow is reduced, and the tone of the bamboo flute is adjusted to be low.

It can be seen, the utility model provides a pair of whole section tunable bamboo flute, the tuning piece that fixed plate and baffle that has relative bending are constituteed is located to set up through blowing at the flute pipe, the utilization extends to the direction that blows the air current that downthehole baffle can guide entering flute pipe cavity, and through the angle of bending between adjusting the baffle and the fixed plate, thereby the incident angle of the air current that control gets into flute pipe cavity, in order to reach the purpose of adjusting the bamboo flute pitch, further improve the effect of playing, the tuning piece is fixed in the flute pipe surface and can not lead to the fact destruction to bamboo flute body structure simultaneously, the authenticity of bamboo flute sound has been guaranteed.
