Description

Vertical blowing national wind instrument

Technical field:

the utility model relates to a national wind instrument, which is an improvement on a vertical wind instrument with a back hole.

The background technology is as follows:

the vertical wind instrument is a kind of wind instrument, including flute, clarinet, ruler eight, cucurbit flute, suona, etc. most of these instruments have back holes. During playing, the musical instrument is not in a vertical direction generally, because the player must lower his head, and the performance image is bad; meanwhile, the musical instrument is not in the horizontal direction, so that the musical instrument can shield the face of the player, and the audience is not benefited to appreciate the expression of the player. Typically, the instrument is played with its axis at an acute angle of 20 to 60 degrees from vertical. In this way, the mouth water (saliva) of the player goes down the tube and flows out from the back hole, and this not only wets the thumb of the player and affects the sanitation and hygiene, but also affects the tone and the emotion of the player.

The utility model comprises the following steps:

the utility model discloses a vertical playing national wind instrument, and aims to create a vertical playing national wind instrument capable of completely avoiding water flowing out of a back hole during playing.

The purpose of the utility model is realized in the following way: a plastic tube which is a little longer than the thickness of the wall of the musical instrument is inlaid in a back hole of the traditional vertical wind instrument, namely inlaid sleeve, and the inner end of the plastic tube is a little higher than the inner wall of the musical instrument. Thus, the water of the player flows down along the two sides of the plastic barrel, bypasses the back hole and flows out from the lower opening of the musical instrument. The purpose that the mouth water does not flow out from the back hole is achieved.

The technical characteristics of the utility model are as follows: in the back hole of the instrument body, a sleeve is fixedly connected, the sleeve is round, the inner end face is a plane, the outer end face is an arc face, and the length of the sleeve is longer than the wall thickness of the instrument body.

The beneficial effects of the utility model are as follows: during playing, the water flowing out of the back hole can be completely avoided, the fingers are prevented from being polluted, and the cleanness and the sanitation are maintained.

Description of the drawings:

the following description is made with reference to the accompanying drawings.

Fig. 1 is an enlarged partial perspective cross-sectional view of the utility model, taken as an example of a "vertical bamboo flute", near the back hole.

Fig. 2 is an enlarged cross-sectional view of the present utility model taken along the center line of the back hole, taking the vertical bamboo flute as an example.

In the figure: 1. the instrument body, 2, the front sound hole, 3, the inlay sleeve and 4, the back hole.

The specific embodiment is as follows:

the utility model comprises a musical instrument body 1, a front sound hole 2, a inlay sleeve 3 and a back hole 4.

The instrument body 1 is a pipe body of a wind instrument, and the utility model is illustrated by taking a national vertical wind instrument 'vertical bamboo flute', so the instrument body 1 is the bamboo flute. The front of the instrument body 1 is provided with a front sound hole 2, the back of the instrument body 1 is provided with a back hole 4, and the back hole 4 is the sound hole existing on the original instrument. The back hole 4 is internally inlaid with the inlaid sleeve 3, the inlaid sleeve 3 is a newly added plastic piece, the inlaid sleeve 3 is in a shape of a right circular sleeve, an inner end (one end entering the instrument body 1) port is a plane perpendicular to a central line, an outer side port opening is a curved surface which is an arc-shaped curved surface with the same radius as the instrument body 1, an inner circular hole is a standard cylindrical through hole, an outer circle is in a stepped cylindrical shape, and a round platform step with a slightly larger diameter is reserved on the outer side (curved surface side) close to the instrument body 1.

During installation, the plane end of the insert 3 can be inwards plugged into the back hole 4 of the instrument body 1 according to the direction that the outer cambered surface is parallel to the outer column surface of the instrument body 1, and as the outer end of the insert 3 is slightly thicker in steps, some resistance exists when the insert is close to the plug, and just as the tight fit fixed connection without any gap between the outer cambered surface of the insert 3 and the back hole 4 is ensured.

Because the insert 3 is inserted into the back hole 4 of the original musical instrument without any processing, the diameter of the center hole of the insert 3 is smaller than that of the original back hole 4, so that the sounding tone of the back hole 4 is slightly higher than that of the original back hole because the aperture is smaller; however, due to the presence of the insert 3, when the finger pressing the back hole is released to play the sound of the back hole, the air column of the pipeline becomes longer, and the sound tone of the back hole 4 becomes lower than the original tone, so that the tone becomes higher just after the hole becomes smaller. The size of the inner aperture (the smaller the sound, the higher the sound) and the length (the longer the sound, the lower the sound) of the insert 3 is properly selected, so that the sound tone (the sound level) of the back hole is unchanged after the insert 3 is installed and when the insert 3 is not installed in the original musical instrument.

When playing, when the player takes the mouth water down along the pipe, the inner end of the insert 3 is higher than the pipe wall due to the insert 3, the mouth water can flow to the two sides of the insert 3 with lower position, along the two outer sides of the insert 3, flow to the inner wall of the bottom instrument body 1 of the back hole 4, and finally flow out through the opening at the lower part of the instrument body 1.
