The roller 49 abuts against the semitone cam 47 and the vibration cam 48, the upper casing 41a mounted on the upper portion of the lower casing 41b, and one end thereof protrudes to the front surface of the upper casing 41a. The middle is bent at right angles, the other end of which protrudes to the lower surface of the lower casing 41b, and the hose 32 at the other end thereof. ) Is connected to the nozzle 44, three springs (not shown) mounted to the lower surface of the nozzle and the lower inner surface of the lower casing 41b, the middle of the upper surface of the upper casing (41a) Is screwed to the front end of the height adjusting portion 42, the upper surface of the upper casing 41a to adjust the height of the nozzle 44 by pressing the middle portion of the nozzle 44 is screwed to the nozzle ( It consists of an angle adjuster 42 for adjusting the discharge angle of 44.

The discharge part 40 configured as described above operates as follows.

Depending on the score of the performance, the system can play normal, semitone, and vibrating sounds, that is, vibration mode.

Before playing, the height and angle of the nozzle 44 are adjusted using the height adjusting part 42 and the angle adjusting part 43 of the discharge part 40 so that the normal state, that is, the lower casing 41b is Optimum sound is produced in close contact with the base 41.

In the case of the normal sound playing, the control unit moves the discharge part 40 to the pipe set in advance according to the pitch pitch length, and simultaneously controls the valve 34 to supply compressed air.

As such, when compressed air is supplied, vibration of the air is generated in the pipe to generate a corresponding sound.

In order to play the semitone and play the vibration mode, the ejection angle of the nozzle should be changed. As shown in FIGS. 6 and 7,

The motor shaft 46a is connected to the rotating shaft of the motor 46 mounted on the base 41 of the discharge part 40.

The motor shaft 46a is equipped with a semitone cam 47 used for semitone playing and a vibrating cam 48 used for vibration mode playing, wherein the semitone cam 47 and the vibrating cam 48 are respectively different directions. It can only rotate.

The lower casing 41b is provided with a roller 49 that abuts against the semitone cam 47 and the vibrating cam 48 to change the discharge angle of the nozzle 44.

The semitone cam 47 and the vibration cam 48 for the semitone playing and the vibration mode playing are configured as follows.

The semitone cam 47 is formed in an elliptical shape and rotatably mounted with respect to the motor shaft 46a. The semitone cam latch 47a is mounted to one side thereof to induce one direction of the semitone cam 47. A halftone cam stopper which acts on the outer circumferential surface of the motor shaft 46a in contact with the halftone cam latch 47a to allow the halftone cam 47 to rotate in only one direction. 47b) is mounted.

In addition, the vibration cam 48 has a structure having three protrusions, and is rotatably mounted on one side of the semitone cam 47 of the motor shaft 46a, and the vibration cam 48 on one side thereof. A vibration cam latch 48a for inducing one direction (in the opposite direction to the semitone cam) and mounted on one outer circumferential surface of the motor shaft 46a in contact with the semitone cam latch 48a. 48b), the pain relief cam stopper 48b allows the vibration cam 48 to rotate in the opposite direction with respect to the semitone cam 47 only.

The playing of the semitone using the configuration for playing the semitone and the vibration mode configured as described above is performed as follows.

The controller 10 is configured to direct the air discharge angle of the nozzle 44 downward at an angle of about 45 degrees in preparation for the normal state when the currently input loudness is a halftone of the pipe. The long shaft portion of the semitone cam 47 is brought into contact with the roller 49 by rotating the 46 at a predetermined rotational angle in a predetermined direction (for example, forward rotation).

When the semitone cam 47 is rotated as described above and the long axis portion is in contact with the roller 49, the lower casing 41b is rotated about the hinge shaft 45 by the roller 49 corresponding thereto.

Since 48a) is set in reverse, the vibration cam 48 is not caught by the vibration cam stopper 48b so that the vibration cam 48 does not rotate along the motor shaft 46a.

As described above, the semitone play continues for the length of the corresponding note, and then the semitone cam 47 is returned to the original position by the controller 10 to return to the normal tone play state.

In addition, the vibration sound, that is, for the vibration performance, the vibration angle of the pitch is generated by repeating the discharge angle of the nozzle 44 at a predetermined period within the range of the normal sound playing angle and the semitone playing angle. The motor 46 is rotated as opposed to the case of the semitone. Therefore, the vibration cam 48 is rotated by the vibration cam latch 48a which acts in opposition to the halftone cam latch 47a while the nozzle 44 is discharged at three times the rotation speed of the motor shaft 46a. The angle is changing.

At this time, the change in the discharge angle of the nozzle 44 can be changed slowly or quickly according to the sheet music state of the music to be played, which is possible by slowing down or increasing the rotation speed of the motor 46.

On the other hand, in the above embodiment has been described as an example of playing automatically using the music score data stored in advance in the memory 16 connected to the control unit 10, the keyboard corresponding to each pipe 72 of the pan flute 70 And a keyboard module (not shown) for outputting respective keyboard signals, and when a player plays the keyboard of the keyboard module like a piano, the keyboard signal of the keyboard operated by the user is controlled by the controller ( 10), the control unit 10 can also be used as a demonstration instrument by playing the pipe preset for each key using the discharge unit 40.
