Abstract

<P>PROBLEM TO BE SOLVED: To add a light emitting function for Naruko(clapper), which is used as stage properties of Japanese dance, without varying the size of the Naruko so as to realize visual effect besides acoustic effect. <P>SOLUTION: Naruko 1 includes a base plate 2 and at least one bar shaped member 3 which is mounted on the plate 2 through a shaft 7 that is provided on one tip part of the member 3 and generates sound by the other tip part of the bar shaped member 3 that hits the plate 2. A piezoelectric generating element 4 made of piezoelectric material is mounted on the Naruko 1. When the bar shaped member 3 hits the plate 2, a light emitting element 5 is turned on by electromotive force generated by the element 4. The Naruko 1 does not necessarily require a power supply such as a battery or the like and the light emitting function is realized while keeping the size and the weight small. The element 4 is also mounted on the plate 2 side and the power supply such as a battery or the like is singly or commonly used. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明が属する技術分野】
本発明は、祭礼や催事におけるアトラクションの舞踊などの、小道具として用いられる鳴子に関わり、さらに詳しくは、音響効果と視覚効果を併せ持つ鳴子に関するものである。
【0002】
【従来の技術】
鳴子は、板状の部材と棒状の部材を組み合わせ、板状の部材を棒状の部材で叩くように構成することで音を発生させ、元来田畑において害鳥などを追い払うために用いられてきたものである。このような目的で用いる鳴子は、短く細い竹筒を板状の部材に添えて吊り下げ、板状の部材に取り付けた縄を引くことで、板状の部材を揺動させ、竹筒で板状の部材を叩き、音を生じさせるように構成されている。
【0003】
一方で、鳴子は舞踊などで、踊り手の動作に伴って音を発生させ、舞踊に音響効果を付与する小道具としても使用されている。この場合は、鳴子を把持できるように、柄を設けるとともに、板状の部材を小型化し、棒状の部材の一端を回動可能な軸を介して板状の部材に取り付け、鳴子を動かした際に、棒状の部材の他端が揺動して板状の部材を叩き、叩打音を発生させる構造となっている。
【0004】
そして近年、小道具としての鳴子においては、棒状の部材の可動側の端部に発光ダイオードなどの発光素子を取り付け、踊り手の手の動きによって、発光素子が点灯する機能を付与して、音響効果の他に、視覚的な効果をも発現する機能を具備したものが使用されている。
【0005】
このような鳴子では、リチウム電池などの小型電池を電源として用いている。しかし、電池を取り付けた場合、電池の大きさの分だけ鳴子全体が大型するばかりでなく、重量も増加せざるを得ないという問題があった。
【0006】
一方で、発光素子などの電源として、圧電材料を用いた素子に関する技術が開示されている。その一例として、次に示す特許文献1がある。
【0007】
【特許文献1】
特開2001−339963
【0008】
前記特許文献1には、圧電セラミックス板と弾性板を組み合わせた、バイモルフ型圧電発電装置と発光ダイオードを接続した発光装置が開示されている。しかし、この技術は起電力を大きくすることが主たる目的であり、舞踊などの小道具として用いるには、必ずしも小型軽量化に十分対応していないものであった。
【0009】
また、前記の鳴子に対して期待される発光強度は、照明が目的ではないので、視認できる程度で十分であり、特許文献1に開示されている圧電発光装置よりも、小型軽量のものが望ましく、電池などの電源と併用する場合は、さらに小型軽量のものが望ましい。
【0010】
【発明が解決しようとする課題】
従って本発明の技術的な課題は、小型軽量で、片手による把持が可能で、舞踊を演じる際に、自由に操作でき、しかも、予め取り付けた発光素子が、手の動きに応じて点灯する鳴子を提供することにある。
【0011】
【課題を解決するための手段】
本発明は、圧電発電素子を用いることで、発光素子に電力を供給することを検討した結果、なされたものである。
【0012】
即ち、本発明は、基板と、一方の端部に設けられた軸を介して前記基板に取り付けられた少なくとも1本の棒状の部材を含み、前記棒状の部材の他方の端部が基板を叩打することにより、音を発生する鳴子において、前記基板または前記棒状の部材の少なくともいずれかに発光素子が取り付けられ、前記基板または前記棒状の部材の少なくともいずれかに取り付けられた、電池または圧電発電素子の少なくともいずれかを含む電源により、前記発光素子を点灯することを特徴とする鳴子である。
【0013】
また、本発明は、前記棒状の部材が前記基板を叩打する際に、前記圧電発電素子に発生する電力により、前記発光素子を点灯させることを特徴とする、前記の鳴子である。
【0014】
本発明の鳴子は、前記のように発光素子を点灯するための電力を、棒状の部材の一部を構成する圧電発電素子から供給するため、電池などの電源を取り付けることが、必ずしも必要ではなく、小型軽量となり、扱いが容易である。また、電池の交換や充電という煩わしい作業や、特別なメンテナンスを不要とすることも可能なので、何時、どこでも使用できるという特長がある。
【0015】
さらに、圧電発電素子の特徴から、棒状の部材が板状の部材を叩くときの電力を利用するので、発光素子の点灯を制御するための回路を要しないことも、小型軽量化には有利である。しかしながら、特別に発光強度を大きくしたい場合は、電池などの副次的な電源を併用してもよいことは、勿論である。
【0016】
そして、本発明に用いられる圧電発電素子としては、チタンジルコン酸亜鉛系の材料を代表とするセラミックス材料や、フッ化ビニリデンと三フッ化エチレンの共重合体を代表とする高分子材料などがあるが、起電力の大きさを考慮すると、セラミックス材料が望ましい。発光素子としては、小型軽量という観点から、発光ダイオードが望ましい。
【0017】
また、圧電発電素子の構造としては、モノモルフ型、ユニモルフ型、バイモルフ型など、様々な構造が使用可能である。これらの中で、バイモルフ型は、小さな力で比較的高電圧が得られる。
【0018】
【発明の実施の形態】
次に、具体的な図を参照しながら、本発明の実施の形態について説明する。
【0019】
図1は、本発明の実施の形態に係る鳴子の一例を示す斜視図である。また、図2は、図1における圧電発電素子と発光素子の概略を示す斜視図である。図1、図2において、1は鳴子、2は基板、3は棒状の部材、4は圧電発電素子、5は発光素子、6は突起、7は棒状の部材3を基板2に取り付けるための軸、8は手で把持するための柄、9はリード線である。突起6を設ける理由は、棒状の部材3が、基板2を叩打する際に、圧電発電素子4に大きな歪みを与え、より大きな起電力を得ることである
【0020】
この例では、基板2と棒状の部材3を木材で構成したが、ポリカーボーネートなどの比較的硬質の高分子材料を用いてもよく、使用者が所望する音質によって使い分けられる。また、圧電発電素子は、材料としてチタンジルコン酸亜鉛系のセラミックスを用い、バイモルフ型の構造を具備し、発光素子5は発光ダイオードである。しかし、これらに限定されるものでないことは勿論である。
【0021】
また、特に例を図示しないが、圧電発電素子4を埋め込む形で基板2側に設けてもよいし、基板2と棒状の部材3の両側に設け、発光素子の発光強度を大きくすることも可能である。さらに、リチウム電池のような小型の電源の単独使用または、圧電発電素子との併用も可能である。
【0022】
【発明の効果】
以上に説明したように、本発明によれば、小型軽量で発光機能を備えた鳴子を提供することができる。これによって、舞踊などの小道具としての鳴子を用いることができる機会が増加することが期待できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a Naruko used as a prop, such as a dance of an attraction in a festival or an event, and more particularly, to a Naruko having both an acoustic effect and a visual effect.
[0002]
[Prior art]
Naruko is a combination of a plate-shaped member and a rod-shaped member, and a sound is generated by striking the plate-shaped member with a rod-shaped member. It is. Naruko used for such a purpose, a short thin bamboo tube is attached to a plate-shaped member and suspended, and a rope attached to the plate-shaped member is pulled to swing the plate-shaped member. It is configured to strike a member to generate a sound.
[0003]
On the other hand, Naruko is a dance and the like, and is also used as a prop to generate a sound in accordance with a dancer's motion and to give a sound effect to the dance. In this case, the handle is provided so that the sounding member can be gripped, the plate-shaped member is downsized, and one end of the rod-shaped member is attached to the plate-shaped member via a rotatable shaft, and the sounding member is moved. In addition, the other end of the rod-shaped member swings and strikes the plate-shaped member to generate a tapping sound.
[0004]
In recent years, in the case of Naruko as a prop, a light emitting element such as a light emitting diode is attached to the movable end of a rod-shaped member, and a function of lighting the light emitting element by the movement of a dancer's hand is provided, thereby providing an acoustic effect. In addition, a device having a function of expressing a visual effect is used.
[0005]
In such a Naruko, a small battery such as a lithium battery is used as a power source. However, when a battery is attached, there is a problem that not only does the entire naruko become larger by the size of the battery, but also the weight must be increased.
[0006]
On the other hand, a technique regarding an element using a piezoelectric material as a power source of a light emitting element or the like is disclosed. As an example, there is Patent Document 1 shown below.
[0007]
[Patent Document 1]
JP-A-2001-339963
[0008]
Patent Document 1 discloses a light emitting device in which a bimorph type piezoelectric power generating device and a light emitting diode are connected, in which a piezoelectric ceramic plate and an elastic plate are combined. However, the main purpose of this technology is to increase the electromotive force, and the technology has not always been sufficiently small and lightweight for use as props such as dances.
[0009]
In addition, the luminous intensity expected for the above-mentioned naruko is not sufficient for the purpose of illumination, so that it is enough to be visually recognized. When used together with a power source such as a battery, a smaller and lighter one is desirable.
[0010]
[Problems to be solved by the invention]
Therefore, a technical problem of the present invention is that a small and light-weighted, light-emitting element which can be freely operated when performing a dance, and in which a light-emitting element mounted in advance is turned on according to hand movements. Is to provide.
[0011]
[Means for Solving the Problems]
The present invention has been made as a result of studying power supply to a light emitting element by using a piezoelectric power generating element.
[0012]
That is, the present invention includes a substrate and at least one rod-shaped member attached to the substrate via a shaft provided at one end, and the other end of the rod-shaped member strikes the substrate. By doing so, in a sound generator that generates sound, a light emitting element is attached to at least one of the substrate and the rod-shaped member, and a battery or a piezoelectric power generation element is attached to at least one of the substrate and the rod-shaped member. Wherein the light emitting element is turned on by a power supply including at least one of the following.
[0013]
Further, the present invention is the above-mentioned sound element, wherein the light-emitting element is turned on by electric power generated in the piezoelectric power generation element when the rod-shaped member strikes the substrate.
[0014]
The sounding element of the present invention supplies the power for lighting the light emitting element as described above from the piezoelectric power generation element constituting a part of the rod-shaped member, so that it is not always necessary to attach a power supply such as a battery. It is small, lightweight and easy to handle. In addition, since it is possible to eliminate troublesome work such as battery replacement and charging and special maintenance, it can be used anywhere and anytime.
[0015]
Furthermore, because of the characteristic of the piezoelectric power generating element, since the rod-shaped member uses electric power when hitting the plate-shaped member, a circuit for controlling lighting of the light-emitting element is not required, which is also advantageous for reducing the size and weight. is there. However, it is needless to say that a secondary power supply such as a battery may be used together when it is desired to particularly increase the light emission intensity.
[0016]
Examples of the piezoelectric power generating element used in the present invention include a ceramic material represented by a zinc-zirconate-zinc-based material and a polymer material represented by a copolymer of vinylidene fluoride and ethylene trifluoride. However, in consideration of the magnitude of the electromotive force, a ceramic material is desirable. As the light emitting element, a light emitting diode is desirable from the viewpoint of small size and light weight.
[0017]
Various structures such as a monomorph type, a unimorph type, and a bimorph type can be used as the structure of the piezoelectric power generating element. Among them, the bimorph type can obtain a relatively high voltage with a small force.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to specific drawings.
[0019]
FIG. 1 is a perspective view showing an example of a sounding rim according to an embodiment of the present invention. FIG. 2 is a perspective view schematically showing the piezoelectric power generating element and the light emitting element in FIG. 1 and 2, reference numeral 1 denotes a ring, 2 denotes a substrate, 3 denotes a rod-shaped member, 4 denotes a piezoelectric power generating element, 5 denotes a light-emitting element, 6 denotes a protrusion, and 7 denotes a shaft for attaching the rod-shaped member 3 to the substrate 2. , 8 is a handle to be gripped by hand, and 9 is a lead wire. The reason for providing the protrusions 6 is that when the rod-shaped member 3 strikes the substrate 2, the rod-shaped member 3 gives a large distortion to the piezoelectric power generating element 4 and obtains a larger electromotive force.
In this example, the substrate 2 and the rod-shaped member 3 are made of wood. However, a relatively hard polymer material such as polycarbonate may be used, and the sound quality desired by the user can be properly selected. Further, the piezoelectric power generating element uses a ceramic of zinc zirconate titanate as a material and has a bimorph structure, and the light emitting element 5 is a light emitting diode. However, it is a matter of course that the present invention is not limited to these.
[0021]
Although not specifically shown, the piezoelectric power generation element 4 may be provided on the substrate 2 side in a buried manner, or provided on both sides of the substrate 2 and the rod-shaped member 3 to increase the light emission intensity of the light emitting element. It is. Further, a small power source such as a lithium battery can be used alone or in combination with a piezoelectric power generating element.
[0022]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a small and light-weight sounding member having a light emitting function. This is expected to increase opportunities for using Naruko as props such as dances.
