  In the conventional slide whistle example, it is possible to produce a sound without steps, and it is possible to play the sound by sliding the sound up and down (glissando). It was. In addition, at the time of low sound, there was a drawback that the slider protruded from the tube body to the outside of the buttock. The outer cover slide type wind instrument of the present invention is intended to solve the drawbacks such as the continuous sound that the slide whistle is difficult to distinguish and the protrusion of the slider to the outside of the tube.

  In order to solve the above-mentioned problems, the present invention devised a wind instrument including a tubular body having a sound hole and an outer cover that is disposed relative to the outer peripheral side of the tubular body. As a means for that, the clearance between the outer shape of the tubular body and the inner shape of the outer cover opposite to the outer shape is set to 0 μm or more so that both can be slid, and a sound hole having a pitch necessary for the tubular body is opened. Open the required number of sound holes for opening the sound holes of the tubular body in the outer cover, and both sound holes are opened in the axial direction of the tubular body, in the periphery of the axial line, or both in accordance with the number of openings. The sound hole of the tubular body can be freely opened and closed by the sliding operation of the outer cover with respect to the tubular body at a fixed position.

  Since the sound hole is opened in the tube body, there is an effect of clearly playing the pitch. The outer cover is relatively arranged on the outer peripheral side of the tube body, and the sound holes of the tube body and the outer cover are also opened in the axial direction and / or the periphery, so that the outer cover does not protrude outside the tube body. is there. Furthermore, there is an effect that the sound hole of the tubular body can be freely opened and closed by a sliding operation of the outer cover in the axial direction of the tubular body at a fixed position.

Embodiments will be described below with reference to the accompanying drawings.
As shown in the front development view of FIG. 1, the musical instrument of the present invention is a wind instrument provided with a tubular body 1 having a sound hole and an outer cover 2 disposed relative to the outer peripheral side of the tubular body 1. The clearance between the outer shape of the tubular body 1 and the inner shape of the outer cover 2 opposite to the outer shape of the tubular body 1 is set to 0 μm or more so that the outer cover 2 can be freely slid. In the prototype example, a clearance of about 30 μm was good, and it was also effective to coat the tube 1 with silicone oil or the like. Then, the pitch sound holes 3 required for the tube 1 are opened, and the required number of open sound holes 4 for the sound holes 3 of the tube 1 are opened in the outer cover 2. The sound holes 3 and 4 are opened in both directions as shown in FIG. 1 when the number of openings is large in the direction of the axis 5 of the tube 1 or in the vicinity of the axis 5 corresponding to the number of openings. In the following, the tubular body 1 and the outer cover 2 shown in FIG. 1 to FIG. 5 are developed in a uniform cylindrical shape with respect to the length that slides in a cross section perpendicular to the axis 5. It may be a flat shape (like ocarina), a triangle, a quadrangle or other polygons. The white circles in each figure indicate that the sound hole of the tube 1 is open and the black circles are closed. The outer cover 2 is assumed to slide in the direction of the axis 5 when the tubular body 1 is in a fixed position. In addition, with respect to an embodiment different from the following FIG. 1 to FIG.

FIG. 2 is a development view of the cylindrical tube body. The sound hole 3 of the tubular body 1 is tuned and opened so as to generate a necessary pitch to the buttock side 8 with respect to the shed 7 such as a whistle on the wharf side 6. When the number of sound holes is large, as shown in FIG. 2, the sound holes are dispersedly opened around the axis 5 of the tube 1 so that the sound holes do not interfere with each other. In this number of sound holes, whistles, recorders, etc., generally provide one octave in the tube 1 and use overtones in the second octave. Semitones can be dealt with by closing the sound hole halfway.
FIG. 3 is a development view of the cylindrical outer cover 2. The outer cover 2 is shaped so that the clearance between the outer shape of the tube body 1 and the inner shape of the outer cover 2 opposite to the outer shape is 0 μm or more. The sound hole 4 of the outer cover 2 is opened as follows. When one A-th sound hole is opened in the tube body 1 from the side of the mouth 7, the outer cover 2 is positioned on the outer cover 2 at a relative position with respect to the A-th sound hole 3 of the tube body 1. A number of sound holes 4 are opened in six directions. Specifically, as shown in FIG. 3, the first sound hole 3 of the tube 1 is one in the sound hole 4 of the outer cover 2, the second is two, the third is three, and so on. Open as follows. The distance between the sound holes of the outer cover 2 may be a length that allows the sound holes of the tubular body 1 to be opened and closed, and may be a long hole in which the sound holes are connected. When the outer cover 2 of FIG. 3 is combined on the outer peripheral side relative to the tube body 1 of FIG. 2, a development view of FIG. 1 is obtained. FIG. 1 shows a state in which all sound holes of the tube 1 are open.
FIG. 4 shows a state in which the outer cover 2 is slid to the buttock side 8 by one sound hole from the state in which the sound hole of the tube body 1 in FIG. 1 is fully open. Slides are used with a separate guide.
FIG. 5 shows a state in which the sound hole of the tube body 1 in FIG. 1 is fully open, and the outer cover 2 is slid to the buttock side 8 by the entire sound hole, and the sound holes of the tube body 1 are all closed. Show.

  FIG. 6 shows an example of a musical instrument in which some of the sound holes of the tube 1 are opened and closed by the outer cover 2. In this example, a whistle or a recorder is used to open and close several sound holes 3 in the tube 1 using a finger of one hand and open and close the remaining sound holes in the tube 1 with sound holes 4 in the outer cover 2. A sound hole for alto is added to the buttock side of the soprano recorder, and only the opening and closing of the added sound hole is opened and closed by the outer cover 2, so that it is possible to produce an instrument that can be an alto coder while being a soprano recorder.

  FIG. 7 shows a wind instrument to which the present invention is applied, which can be supported and operated with one hand. By adding a support base 9, the musical instrument of the present invention is configured as a human musical instrument that is particularly handicapped. In this example of the musical instrument, the support / operation lever 10 is provided with a finger or palm grip 11, and a slide operation can be performed with only one hand and only the palm even if the finger is handicapped. The operation of FIG. 7 is performed as follows. The outer cover 2 guides the guide 13 with respect to the tube body 1 at a fixed position by grasping the supporting / operating lever 10 or the grip 11 or inserting the palm into the grip 11 and turning it around the fulcrum 12. To move and play a predetermined pitch. If the 10 levers and 11 grips are adjustable or exchangeable, it is possible to cope with differences in finger sizes.

  The present invention can be newly used as a slide type wind instrument in the field of wind instruments. In particular, since the sound hole of the tubular body can be freely opened and closed by the sliding of the outer cover, it can be used by people who are handicapped. In addition, even an infant or an elderly person who can hardly open and close the sound hole can easily use it.
