Description
ペットボトルなどの容器を用いたリコーダーに関する。 The present invention relates to a recorder using a container such as a PET bottle.
子供や大人が楽しめ音をだす玩具のひとつに水笛がある。水笛は、吹口から水面に向かって空気を送り込み、水面が揺れることにより、揺らいだ音程をつくることができる。この水笛には音階を変えることができないという課題があった。 One of the toys that children and adults can enjoy and sound is a water flute. The water whistle blows air from the mouth toward the surface of the water, and the water surface sways, thereby creating a fluctuating pitch. This whistle had a problem that the scale could not be changed.
水笛では、音階を変えることができないという課題があった。
また、従来、筒状に穴が開いていて、指でふさぐ穴の位置によって音階を作るリコーダーが存在していたが、小さい子どもや高齢者、片手が不自由で両手での運指が困難な人でも楽しみながら使用でき、容易に音階を吹けるリコーダーがなかった。With the water flute, there was a problem that the scale could not be changed.
In the past, there was a recorder that had a hole in the shape of a cylinder and made a musical scale based on the position of the hole that was closed with a finger. There was no recorder that could be used by people and enjoyed the scale easily.
リコーダー本体（２）と、水（４）が入った容器（３）からなり、リコーダー本体（２）は、吹口（２１）と、下管本体（２３）と、リコーダー（２）を水が入った容器（３）の開口部（３１）に取り付けるための取付部（２２）を備えたことを特徴とするリコーダー。 It consists of a recorder body (2) and a container (3) containing water (4), and the recorder body (2) is filled with water through the outlet (21), the lower pipe body (23) and the recorder (2). A recorder provided with an attaching portion (22) for attaching to an opening (31) of a container (3).
水（４）を入れる容器（３）に弾性変形可能な材質あるいは形状を有する容器を用いたことを特徴とするリコーダー。 A recorder characterized by using a container having a material or shape capable of being elastically deformed as a container (3) for containing water (4).
水（４）の入った容器（３）の開口部（３１）に取付部（２２）を取り付けることにより、容器内が密閉されて外からの空気の出入りがしにくくなり、容器の外側からかける圧力（５）を加減することによって、容器（３）内あるいはリコーダー本体（２）の下管本体（２３）内の水（４）の水位が上下することを特徴とするリコーダー。 By attaching the attachment portion (22) to the opening (31) of the container (3) containing water (4), the inside of the container is sealed, and it is difficult for air to enter and exit from outside, and the container is applied from the outside of the container. A recorder characterized in that the level of water (4) in the container (3) or in the lower tube body (23) of the recorder body (2) rises and falls by adjusting the pressure (5).
下管本体（２３）の表面に、音程をしめすための目盛りを備えたことを特徴とするリコーダー。 A recorder provided with a scale on a surface of a lower tube main body (23) for indicating a pitch.
運指の知識がなくても、容器を握って変形させることにより下管本体内部の水位が変化して簡単に音階が作れるので、だれにでも楽しめるリコーダーを提供することができる。 Even if there is no knowledge of fingering, since the water level inside the lower tube main body changes by grasping and deforming the container, a musical scale can be easily created, so that a recorder that can be enjoyed by anyone can be provided.
図１は、本発明の水を入れた容器を用いたリコーダーの構成で、（ａ）はリコーダー、（ｂ）はリコーダー本体を示す。 本発明のリコーダーは、リコーダー本体（２）と、水（４）が入った容器（３）からなり、リコーダー本体（２）は、図１（ｂ）に示すように、吹口（２１）と取付部（２２）と下管本体（２３）から構成され、吹口（２１）には空気が出入りする窓（２４）を設ける。
下管本体（２３）は、吹口（２１）と取付部（２２）に対して着脱可能としてもよいし、一体物として成型加工されているもよい。
リコーダー本体（２）を、取付部（２２）によって水（４）の入った容器（３）の開口部（３１）に取り付ける。水の量は、加圧しない普通の状態において、下管本体（２３）が水に浸っているように調節する。FIGS. 1A and 1B show the configuration of a recorder using a water-containing container according to the present invention. FIG. 1A shows a recorder, and FIG. 1B shows a recorder main body. The recorder according to the present invention comprises a recorder body (2) and a container (3) containing water (4), and the recorder body (2) is attached to an outlet (21) as shown in FIG. 1 (b). consists unit (22) and the lower tube body (23), the吹口(21) providing a window (24) into and out of the air.
The lower pipe main body (23) may be detachable from the outlet (21) and the mounting portion (22), or may be molded as an integral body.
The recorder body (2) is attached to the opening (31) of the container (3) containing water (4) by the attaching portion (22). The amount of water is adjusted so that the lower tube body (23) is immersed in water in a normal state without pressurization.
図２は、リコーダーを使用したときの図である。容器は、押さえても元の形状を戻ることができる弾性変形可能な材質あるいは形状を有するものを用いる。（ａ）は、容器を押さえない場合、（ｂ）は容器を押さえた場合を示す。
図２（ａ）に示すように、容器を押さえないときは、下管本体（２３）内部と外部の水位はほぼ同位であり、図中のＡの高さになるものとする。
容器の周囲から圧力（５）を加えてリコーダーを吹いたとき、容器が変形し、容器内の水（４）が押されて、下管本体（２３）内部の水位が上昇する。
そのときの外部の水位をＢ、内部の水位Ｃとする。リコーダーの音程は、吹口（２１）の窓（２４）から下管本体（２３）の水面までの高さに依存するので、水位が高くなったときは、共鳴する波長が短くなり、高い音が発生する。
加圧をやめると容器は元の形に戻り、水位Ｂ，Ｃが元の位置Ａの高さまで戻る。水位の変化に伴い、加圧しなかったときの音程に戻る。このように容器に掛ける圧力の加減により、音程が変化する。FIG. 2 is a diagram when a recorder is used. The container is made of a material or shape that can be elastically deformed so that it can return to its original shape even when pressed. (A) shows the case where the container is not pressed, and (b) shows the case where the container is pressed.
As shown in FIG. 2 (a), when the container is not pressed, the water levels inside and outside the lower pipe main body (23) are almost at the same level, and assume the height A in the figure.
When the recorder is blown by applying pressure (5) from around the container, the container is deformed, the water (4) in the container is pushed, and the water level inside the lower pipe main body (23) rises.
The external water level at that time is B and the internal water level is C. Since the pitch of the recorder depends on the height from the window (24) of the outlet (21) to the water surface of the lower pipe body (23), when the water level becomes high, the wavelength of resonance becomes short, and Occur.
When the pressurization is stopped, the container returns to the original shape, and the water levels B and C return to the original height of the position A. As the water level changes, the pitch returns to the pitch when no pressure was applied. As described above, the pitch is changed by adjusting the pressure applied to the container.
下部本体（２３）に音程に対応する目盛りを備えておくと、目盛りを見ながら音階が演奏でき、かつ同じ音程の音を再現することができる。 If the lower body (23) is provided with a scale corresponding to a pitch, the scale can be played while looking at the scale, and a sound having the same pitch can be reproduced.
小さい子どもや高齢者、片手が不自由で両手での運指が困難な人でも、楽しみながら使用でき、容易に音階を吹けるリコーダーを提供する。 Provide a recorder that can be used with fun and easily play the scale even for small children, the elderly, and those who have difficulty in fingering with both hands because of one hand disability.
