　しかしながら、上記特許文献１及び２の振動発電機においては、振動エネルギーを電気エネルギーに変換する際の効率が悪いという問題があることに本発明者は着目し、これを課題とした。 However, the present inventors paid attention to the problem that in the vibration generators of Patent Documents 1 and 2 described above, there is a problem that the efficiency in converting vibration energy into electric energy is low, and this is a problem to be solved.
　すなわち、本発明は、発電効率を向上する振動ダイナモ装置を提供することを課題とする。 That is, an object of the present invention is to provide a vibration dynamo device that improves power generation efficiency.
　本発明者は、上記特許文献１及び２の振動発電機において発電効率が悪いという問題は、上記特許文献１及び２の可動子は、筒状部材内部の空間と同じ断面形状を有しているので、筒状部材内を可動子が往復移動する際に、筒状部材と可動子との摺動抵抗が大きいことに起因していることを見出した。このため、本発明者は、発電効率を向上するために、筒状部材と可動子との摺動面積を低減することに着目し、本発明を完成させた。 The present inventor has the problem that the power generation efficiency is poor in the vibration generators of Patent Documents 1 and 2, and the mover of Patent Documents 1 and 2 has the same cross-sectional shape as the space inside the cylindrical member. Therefore, the present inventors have found that the sliding resistance between the cylindrical member and the mover is large when the mover reciprocates in the cylindrical member. For this reason, in order to improve electric power generation efficiency, this inventor paid attention to reducing the sliding area of a cylindrical member and a needle | mover, and completed this invention.
　すなわち、本発明の振動ダイナモ装置は、非磁性体の筒状部材と、この筒状部材の外周に配置されたコイルと、筒状部材の延在方向に沿って往復運動が可能な状態で筒状部材の内部に収容され、マグネットを含む振動部材とを備え、振動部材において筒状部材と接する部分は、球体である。 That is, the vibration dynamo device of the present invention is a cylindrical member that is capable of reciprocating along a non-magnetic cylindrical member, a coil disposed on the outer periphery of the cylindrical member, and the extending direction of the cylindrical member. The vibration member including the magnet and housed in the inside of the cylindrical member, and the portion of the vibration member that contacts the cylindrical member is a sphere.
　本発明の振動ダイナモ装置によれば、振動部材が往復運動する際に振動部材において筒状部材と接する部分が球体であるので、振動部材と筒状部材との摺動部分は点接触となる。このため、振動部材と筒状部材との摺動面積を低減できるので、振動部材が振動する際の抵抗を低減できる。したがって、振動（運動）エネルギーを電気エネルギーに変換する効率を向上できるので、本発明の振動ダイナモ装置は、発電効率を向上できる。 According to the vibration dynamo device of the present invention, when the vibration member reciprocates, the portion of the vibration member that contacts the cylindrical member is a sphere, so that the sliding portion between the vibration member and the cylindrical member is in point contact. For this reason, since the sliding area of a vibration member and a cylindrical member can be reduced, the resistance at the time of a vibration member vibrating can be reduced. Therefore, since the efficiency of converting vibration (kinetic) energy into electric energy can be improved, the vibration dynamo device of the present invention can improve power generation efficiency.
　本発明の振動ダイナモ装置において、上記振動部材は、３つ以上の要素を含み、両端に位置する要素は球体である。 In the vibration dynamo device of the present invention, the vibration member includes three or more elements, and the elements positioned at both ends are spheres.
　振動部材が往復運動する際に、振動部材を構成する球体が筒状部材と接する場合には、その接触面積を低減できる。このため、発電効率を向上できる振動ダイナモ装置を実現できる。 When the oscillating member reciprocates, the contact area can be reduced when the sphere constituting the oscillating member contacts the cylindrical member. For this reason, the vibration dynamo device which can improve power generation efficiency is realizable.
　本発明の振動ダイナモ装置において、３つ以上の要素の残部は、球体及び／または柱体であり、両端に位置する球体の外径は、残部の球体及び／または柱体の外径よりも大きい。 In the vibration dynamo device of the present invention, the remaining parts of the three or more elements are spheres and / or columns, and the outer diameters of the spheres located at both ends are larger than the outer diameters of the remaining spheres and / or columns. .
　これにより、振動部材を構成する要素のうち、両端に位置する球体が筒状部材と接するので、振動部材が往復運動する際の振動部材と筒状部材との接触面積をより低減できる。このため、振動ダイナモ装置の発電効率を向上できる。 This makes it possible to reduce the contact area between the vibrating member and the cylindrical member when the vibrating member reciprocates because the spheres located at both ends of the elements constituting the vibrating member are in contact with the cylindrical member. For this reason, the power generation efficiency of the vibration dynamo device can be improved.
　本発明の振動ダイナモ装置において好ましくは、両端に位置する球体はヨーク（継鉄）であり、３つ以上の要素の残部はマグネットである。 In the vibration dynamo device of the present invention, preferably, the spheres located at both ends are yokes (relays), and the remaining three or more elements are magnets.
　ヨークとマグネットとを組み合わせることにより、磁力を有効に利用でき、吸着力が向上する。このため、振動ダイナモ装置の発電効率をより向上できる。 ¡By combining the yoke and magnet, the magnetic force can be used effectively and the attractive force is improved. For this reason, the power generation efficiency of the vibration dynamo device can be further improved.
　本発明の振動ダイナモ装置において、振動部材は、マグネットのみからなってもよい。この場合であっても、振動部材が往復運動する際に、振動部材を構成するマグネットの球体が筒状部材と接するので、筒状部材と振動部材との接触面積を低減できる。このため、振動ダイナモ装置の発電効率を向上できる。 In the vibration dynamo device of the present invention, the vibration member may be composed only of a magnet. Even in this case, when the vibrating member reciprocates, the spherical body of the magnet constituting the vibrating member is in contact with the cylindrical member, so that the contact area between the cylindrical member and the vibrating member can be reduced. For this reason, the power generation efficiency of the vibration dynamo device can be improved.
　なお、本発明の振動ダイナモ装置において、上記３つ以上の要素は、磁力の吸引力で互いを保持していてもよい。 In the vibration dynamo device of the present invention, the three or more elements may hold each other with a magnetic attractive force.
　本発明の振動ダイナモ装置によれば、発電効率を向上することができる。 According to the vibration dynamo device of the present invention, the power generation efficiency can be improved.

　以下、図面に基づいて本発明の実施の形態を説明する。なお、以下の図面において同一または相当する部分には同一の参照符号を付しその説明は繰り返さない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.
　（実施の形態１）
　本発明の一実施の形態の振動ダイナモ装置について説明する。本実施の形態の振動ダイナモ装置１は、筒状部材２と、この筒状部材２の外周に配置されたコイル３と、筒状部材２の内部に収容された振動部材１０と、筒状部材２の両端部に配置された閉鎖部材４と、コイル３を取り囲む筐体５とを備えている。 (Embodiment 1)
A vibration dynamo apparatus according to an embodiment of the present invention will be described. The vibration dynamo device 1 according to the present embodiment includes a tubular member 2, a coil 3 disposed on the outer periphery of the tubular member 2, a vibration member 10 accommodated in the tubular member 2, and a tubular member. 2 is provided with a closing member 4 disposed at both ends of the coil 2 and a casing 5 surrounding the coil 3.
　筒状部材２は、内部が中空の棒状であり、両端は解放されている。本実施の形態の筒状部材２は、図１において左右方向（図１における矢印Ａの方向）に延在している。なお、筒状部材２の外形状及び内形状（中空形状）は特に限定されず、断面視において円形、矩形などが挙げられる。本実施の形態の筒状部材２は、外形状及び内形状は断面視において円柱形状である。なお、本実施の形態の筒状部材の内径（中空形状の直径）は、後述する振動部材１０よりもやや大きい。 The cylindrical member 2 has a hollow rod shape inside and is open at both ends. The cylindrical member 2 of the present embodiment extends in the left-right direction (the direction of arrow A in FIG. 1) in FIG. In addition, the outer shape and inner shape (hollow shape) of the cylindrical member 2 are not specifically limited, A circular shape, a rectangular shape, etc. are mentioned in cross-sectional view. The cylindrical member 2 of the present embodiment has an outer shape and an inner shape that are cylindrical in a sectional view. In addition, the internal diameter (hollow shape diameter) of the cylindrical member of this Embodiment is a little larger than the vibration member 10 mentioned later.
　筒状部材２は、非磁性体で形成されている。非磁性体とは、強磁性体ではない物質で、常磁性体、反磁性体及び反強磁性体を含む。非磁性体として、例えば、アルミニウムなどの金属、プラスチックなどの合成樹脂などが挙げられる。 The cylindrical member 2 is formed of a nonmagnetic material. The non-magnetic material is a material that is not a ferromagnetic material, and includes a paramagnetic material, a diamagnetic material, and an antiferromagnetic material. Examples of the non-magnetic material include metals such as aluminum and synthetic resins such as plastic.
　この筒状部材２の外周には、コイル３が巻回されている。このため、筒状部材２は、コイル３のボビンの役割も担う。本実施の形態のコイル３は、筒状部材２の外周の一部に設けられているが、筒状部材２の全周に設けられていてもよく、筒状部材２の外周の分離した領域に設けられていてもよい。コイル３は、例えばソレノイドコイルである。 The coil 3 is wound around the outer periphery of the cylindrical member 2. For this reason, the cylindrical member 2 also serves as a bobbin for the coil 3. Although the coil 3 of this Embodiment is provided in a part of outer periphery of the cylindrical member 2, you may be provided in the perimeter of the cylindrical member 2, and the area | region which the outer periphery of the cylindrical member 2 isolate | separated May be provided. The coil 3 is a solenoid coil, for example.
　筒状部材２の内部には、筒状部材２の延在方向（図１における矢印Ａの方向）に沿って往復運動が可能な状態で、振動部材１０が設けられている。筒状部材２の外周にコイル３が配置されているので、振動部材１０はコイル３の内部を往復運動する。振動部材１０は、マグネットを含んでおり、振動部材１０の往復運動によってコイル３が電圧を発生する。つまり、振動部材１０は、コイル３の巻軸方向に沿って往復運動するので、コイル３に交流電流が発生する。振動部材１０については、後述する。 The vibrating member 10 is provided inside the cylindrical member 2 in a state in which the cylindrical member 2 can reciprocate along the extending direction of the cylindrical member 2 (the direction of the arrow A in FIG. 1). Since the coil 3 is disposed on the outer periphery of the cylindrical member 2, the vibrating member 10 reciprocates inside the coil 3. The vibrating member 10 includes a magnet, and the coil 3 generates a voltage by the reciprocating motion of the vibrating member 10. That is, since the vibrating member 10 reciprocates along the winding axis direction of the coil 3, an alternating current is generated in the coil 3. The vibration member 10 will be described later.
　筒状部材２の両端部には、閉鎖部材４が設けられている。閉鎖部材４は、筒状部材２の両端の開口を閉塞している。閉鎖部材４により、往復運動をする振動部材１０が筒状部材２の内部に収容される。閉鎖部材４は、非磁性体で形成されており、往復運動による振動部材１０の損傷を低減する観点から、例えば、樹脂、ゴムなどの弾性体で形成されていることが好ましい。 The closing member 4 is provided at both ends of the cylindrical member 2. The closing member 4 closes the openings at both ends of the cylindrical member 2. The vibration member 10 that reciprocates is accommodated in the cylindrical member 2 by the closing member 4. The closing member 4 is made of a non-magnetic material, and is preferably made of an elastic material such as resin or rubber from the viewpoint of reducing damage to the vibration member 10 due to reciprocating motion.
　振動部材１０、筒状部材２、コイル３及び閉鎖部材４を収容するために、筐体５が設けられている。筐体５は、非磁性材料で形成されている。 A housing 5 is provided to accommodate the vibration member 10, the cylindrical member 2, the coil 3, and the closing member 4. The housing 5 is made of a nonmagnetic material.
　また、振動ダイナモ装置１は、コイル３に接続された整流部、充電部などをさらに備えていてもよい（図示せず）。 Moreover, the vibration dynamo device 1 may further include a rectifying unit, a charging unit, and the like connected to the coil 3 (not shown).
　ここで、図１～図５を参照して、振動部材１０について詳述する。振動部材１０において筒状部材２と接する部分は、球体である。 Here, the vibration member 10 will be described in detail with reference to FIGS. A portion of the vibrating member 10 that contacts the cylindrical member 2 is a sphere.
　図１～図５に示すように、振動部材１０は３つ以上の要素１１ａ、１１ｂ、１２ａ、１２ｂ、１３ａ、１３ｂ、１４ａ、１４ｂ、１５ａを含んでおり、３つ以上の要素は、往復運動する方向（図１における矢印Ａの方向）に沿って並列に配置されている。３つ以上の要素のうち、両端に位置する要素１１ａ、１１ｂ、１２ａ、１２ｂは球体である。３つ以上の要素の残部、すなわち両端以外（中央部）に位置する要素１３ａ、１３ｂ、１４ａ、１４ｂ、１５ａは、図１～図３に示す構造（要素１３ａ、１４ａ、１５ａ）では柱体であり、図４及び図５に示す構造（要素１３ｂ、１４ｂ）では球体である。なお、球体及び柱体とは、外形が球体及び柱体を意味し、内部が空洞であるものを含む。また、柱体は、円柱、角柱、ディスク状などを含み、本実施の形態では円柱である。 As shown in FIGS. 1-5, the vibrating member 10 includes three or more elements 11a, 11b, 12a, 12b, 13a, 13b, 14a, 14b, 15a, and the three or more elements are reciprocating. It arrange | positions in parallel along the direction (direction of the arrow A in FIG. 1) to do. Of the three or more elements, the elements 11a, 11b, 12a, 12b located at both ends are spheres. The remaining parts of the three or more elements, that is, the elements 13a, 13b, 14a, 14b, and 15a other than both ends (center part) are columnar bodies in the structure shown in FIGS. 1 to 3 ( elements 13a, 14a, and 15a). Yes, the structure ( elements 13b and 14b) shown in FIGS. 4 and 5 is a sphere. Note that the sphere and the column include those whose outer shape means a sphere and a column, and whose inside is a cavity. Further, the column includes a cylinder, a prism, a disk shape, and the like, and is a cylinder in the present embodiment.
　図１～図５に示すように、両端に位置する球体の外径は、残部の球体及び／または柱体の外径よりも大きい。この場合、両端に位置する球体が、振動部材１０において筒状部材２と接する部分となる。なお、振動部材１０において、両端に位置する２つの球体の外径は、実質的に同じである。実質的に同じとは、振動部材１０が往復運動する際に両端の２つの球体のそれぞれが筒状部材と接することを意味する。 As shown in FIGS. 1 to 5, the outer diameters of the spheres located at both ends are larger than the outer diameters of the remaining spheres and / or pillars. In this case, the spheres located at both ends serve as portions in contact with the cylindrical member 2 in the vibration member 10. In the vibrating member 10, the outer diameters of the two spheres positioned at both ends are substantially the same. Substantially the same means that each of the two spheres at both ends contacts the cylindrical member when the vibrating member 10 reciprocates.
　なお、球体の外径とは直径である。柱体の外径とは、円柱の場合には底面の円の直径であり、柱体の底面がｎ角形（ｎは３以上の整数）の場合には底面の外接円の直径である。 Note that the outer diameter of the sphere is the diameter. The outer diameter of the column is the diameter of the circle on the bottom surface in the case of a cylinder, and the diameter of the circumscribed circle on the bottom surface when the bottom surface of the column is an n-gon (n is an integer of 3 or more).
　図１、図３及び図５に示す構造では、両端に位置する球体（図１、図３及び図５における要素１１ａ、１２ａ）はヨークであり、３つ以上の要素の残部（図１における要素１３ａ、１４ａ、１５ａ、図３及び図５における要素１３ａ、１３ｂ、１４ａ、１４ｂ）はマグネットである。図２及び図４に示す構造では、振動部材１０を構成する要素（図２における要素１１ｂ、１２ｂ、１３ａ、１４ａ、図４における要素１１ｂ、１２ｂ、１３ｂ、１４ｂ）は、マグネットのみからなる。このように振動部材１０を構成する要素が、マグネットからなる場合、または、マグネットとヨークとからなる場合には、磁力の吸引力で保持されるので、本実施の形態の３つ以上の要素は、マグネットのみ、または、マグネットとヨークのみで形成されており、磁力の吸引力のみで互いを保持している。 In the structure shown in FIGS. 1, 3 and 5, the spheres located at both ends ( elements 11a and 12a in FIGS. 1, 3 and 5) are yokes, and the remainder of three or more elements (elements in FIG. 1). 13a, 14a, 15a, elements 13a, 13b, 14a, 14b) in FIGS. 3 and 5 are magnets. In the structure shown in FIGS. 2 and 4, the elements constituting the vibration member 10 (the elements 11b, 12b, 13a, and 14a in FIG. 2, and the elements 11b, 12b, 13b, and 14b in FIG. 4) are made only of magnets. When the elements constituting the vibration member 10 are composed of magnets or are composed of magnets and yokes as described above, the three or more elements of the present embodiment are held by magnetic attraction. These are formed only by magnets or only by magnets and yokes, and hold each other only by magnetic attraction.
　なお、マグネット（磁石）とは、永久磁石である。マグネットは、往復運動する方向（軸方向）に着磁している。着磁（磁化）方法は特に限定されないが、例えば、空芯コイルの中央にマグネット材料を固定し、パルス高電流を流して、軸方向に磁化する方法が挙げられる。また、マグネットの材料は特に限定されないが、高い磁力を示す観点から、Ｎｄ‐Ｆｅ‐Ｂ焼結磁石を用いることが好ましい。 In addition, a magnet (magnet) is a permanent magnet. The magnet is magnetized in the reciprocating direction (axial direction). The magnetization (magnetization) method is not particularly limited. For example, there is a method in which a magnet material is fixed at the center of the air-core coil, a pulse high current is passed, and magnetization is performed in the axial direction. The material of the magnet is not particularly limited, but it is preferable to use a Nd—Fe—B sintered magnet from the viewpoint of showing a high magnetic force.
　また、ヨーク（継鉄）とは、マグネットが持つ吸着力を増幅する軟鉄であり、鉄を含んでいればよく、軟磁性材料を含む。本実施の形態では、球体のヨークとして、鋼球を用いている。 Also, the yoke is a soft iron that amplifies the attraction force of the magnet, and it only needs to contain iron and includes a soft magnetic material. In the present embodiment, a steel ball is used as the spherical yoke.
　なお、図１～図５に示す振動部材１０は、例示であって、筒状部材２と接する部分が球体であれば特に限定されない。例えば、振動部材１０は、２つの要素からなり、この２つの要素は、マグネットの球体であってもよい。 Note that the vibrating member 10 shown in FIGS. 1 to 5 is an example, and is not particularly limited as long as the portion in contact with the cylindrical member 2 is a sphere. For example, the vibrating member 10 includes two elements, and the two elements may be magnet spheres.
　振動部材１０は、筒状部材２の内部を自在に往復運動できる大きさであれば、特に限定されないが、図５に示す振動部材１０を備える振動ダイナモ装置１の筒状部材２及び振動部材１０の具体的寸法の一例を挙げる。筒状部材２の内径は、例えば１０．５ｍｍである。振動部材１０において両端に位置する球体（要素１１ａ、１２ａ）の外径は、例えば１０．０ｍｍである。振動部材１０において中央に位置する残部の球体（要素１３ｂ、１４ｂ）の外径は９．５ｍｍである。 The vibrating member 10 is not particularly limited as long as the vibrating member 10 has a size that can freely reciprocate within the cylindrical member 2, but the cylindrical member 2 and the vibrating member 10 of the vibrating dynamo device 1 including the vibrating member 10 illustrated in FIG. 5. An example of the specific dimensions is given. The inner diameter of the cylindrical member 2 is 10.5 mm, for example. The outer diameter of the spheres ( elements 11a and 12a) located at both ends of the vibration member 10 is 10.0 mm, for example. The remaining spherical body ( elements 13b and 14b) located at the center of the vibration member 10 has an outer diameter of 9.5 mm.
　続いて、主に図１を参照して、本実施の形態の振動ダイナモ装置１の動作について説明する。 Subsequently, the operation of the vibration dynamo device 1 of the present embodiment will be described mainly with reference to FIG.
　まず、振動ダイナモ装置１の筐体５を保持して、筒状部材２の延在方向、すなわち図１における矢印Ａに沿って往復運動する。これにより、筒状部材２の内部において、振動部材１０は、筒状部材２の延在方向に沿って往復運動する。これにより、振動部材１０は筒状部材２の外周に配置されたコイル３内を往復運動することになるので、振動部材１０のマグネットから発生する磁束線がコイル３に直交し、その際に誘導起電力としての誘導電流が発生する。振動部材１０に含まれるマグネットがコイル３内に出入りを繰り返すので、コイル３には交流電流が発生する。 First, the casing 5 of the vibration dynamo device 1 is held and reciprocates along the extending direction of the cylindrical member 2, that is, along the arrow A in FIG. Thereby, the vibration member 10 reciprocates along the extending direction of the cylindrical member 2 inside the cylindrical member 2. As a result, the vibration member 10 reciprocates in the coil 3 disposed on the outer periphery of the cylindrical member 2, so that the magnetic flux lines generated from the magnet of the vibration member 10 are orthogonal to the coil 3, and induction is performed at that time. An induced current is generated as an electromotive force. Since the magnet included in the vibrating member 10 repeatedly enters and exits the coil 3, an alternating current is generated in the coil 3.
　なお、コイル３に発生した交流電流は、コイルの両端に接続された配線（図示せず）を介して整流部（図示せず）に伝達される。整流部によって、交流電流を整流して直流電源にする全波整流が行われ、充電部（図示せず）によって充電される。充電された電流は、電極（図示せず）を介して外部に出力される。外部に出力された電流は、外部装置の負荷に供給され、供給された電流によって駆動する。 Note that the alternating current generated in the coil 3 is transmitted to a rectification unit (not shown) via wiring (not shown) connected to both ends of the coil. Full-wave rectification is performed by the rectification unit to rectify an alternating current into a DC power source, and the battery is charged by a charging unit (not shown). The charged current is output to the outside through an electrode (not shown). The current output to the outside is supplied to the load of the external device and is driven by the supplied current.
　本実施の形態では、振動部材１０が筒状部材２内で往復運動する際、振動部材１０の要素である両端に位置する球体が筒状部材２に接するので、振動部材１０と筒状部材２とが点接触の状態で振動部材１０が摺動する。これにより、振動部材１０と筒状部材との摺動面積を低減できるので、接触抵抗（摺動抵抗）が小さくなる。振動部材１０は動きやすいため、振動ダイナモ装置１に加えられた力による振動部材１０の運動エネルギー（振動エネルギー）をコイル３による電気エネルギーへ効率良く変換できる。したがって、振動ダイナモ装置１の発電効率を向上できるので、電気発生量を高めることができる。 In the present embodiment, when the vibration member 10 reciprocates within the cylindrical member 2, the spheres positioned at both ends, which are elements of the vibration member 10, are in contact with the cylindrical member 2. The vibration member 10 slides in a state of point contact. Thereby, since the sliding area of the vibration member 10 and the cylindrical member can be reduced, the contact resistance (sliding resistance) is reduced. Since the vibration member 10 is easy to move, the kinetic energy (vibration energy) of the vibration member 10 due to the force applied to the vibration dynamo device 1 can be efficiently converted into electric energy by the coil 3. Therefore, since the power generation efficiency of the vibration dynamo device 1 can be improved, the amount of electricity generated can be increased.
　本実施の形態において、図５に示すように、振動部材１０は、３つ以上の要素１１ａ、１２ａ、１３ｂ、１４ｂを含み、３つ以上の要素のそれぞれは球体であり、両端に位置する球体（要素１１ａ、１２ａ）の外径は残部の球体（要素１３ｂ、１４ｂ）の外径よりも大きく、両端に位置する球体はヨークであり、残部の球体はマグネットであることが好ましい。これにより、振動部材１０の往復運動の際の振動部材１０と筒状部材２との接触抵抗を低減できるとともに、中央部のマグネットと両端に位置するヨークとによるヨーク効果を有することで発生磁力を高めることができるので、発電効率をより向上できる。また、振動部材１０が球体からなるので、コストを低減できる。 In the present embodiment, as shown in FIG. 5, the vibration member 10 includes three or more elements 11a, 12a, 13b, and 14b. Each of the three or more elements is a sphere, and spheres positioned at both ends. It is preferable that the outer diameter of the ( elements 11a and 12a) is larger than the outer diameter of the remaining spheres ( elements 13b and 14b), the spheres located at both ends are yokes, and the remaining spheres are magnets. As a result, the contact resistance between the vibrating member 10 and the cylindrical member 2 during the reciprocating motion of the vibrating member 10 can be reduced, and the generated magnetic force can be reduced by having the yoke effect of the central magnet and the yokes located at both ends. Since it can raise, power generation efficiency can be improved more. Further, since the vibration member 10 is made of a sphere, the cost can be reduced.

　続いて、図６～図８を参照して、本実施の形態の照明器具２０の動作について説明する。 Subsequently, the operation of the lighting fixture 20 of the present embodiment will be described with reference to FIGS.
　まず、照明器具２０の取手２２を把持して、筒状部材２の延在方向、すなわち図７における矢印Ａに沿って往復運動する。これにより、実施の形態１と同様に、筒状部材２の内部において、振動部材１０は、筒状部材２の延在方向に沿って往復運動するので、振動部材１０のマグネットから発生する磁束線がコイル３に直交することで、コイル３には交流電流が発生する。コイル３に発生した交流電流は、整流回路８に伝達されて整流され、充電回路９によって充電される。 First, the handle 22 of the luminaire 20 is gripped and reciprocated along the extending direction of the cylindrical member 2, that is, the arrow A in FIG. Thus, as in the first embodiment, the vibrating member 10 reciprocates along the extending direction of the cylindrical member 2 inside the cylindrical member 2, so that the magnetic flux lines generated from the magnet of the vibrating member 10 Is orthogonal to the coil 3, an alternating current is generated in the coil 3. The alternating current generated in the coil 3 is transmitted to the rectifier circuit 8 to be rectified and charged by the charging circuit 9.
　光源２１から発光させる場合には、スイッチ２３をＯＮにする。これにより、充電回路９に充電された電流が、光源２１に伝達されて、発光する。充電回路に充電された電流が少ない場合には、取手２２に内蔵された蓄電池から光源２１に電流を流す。 When the light source 21 emits light, the switch 23 is turned on. As a result, the current charged in the charging circuit 9 is transmitted to the light source 21 to emit light. When the current charged in the charging circuit is small, a current is passed from the storage battery built in the handle 22 to the light source 21.
　光源２１から発光させない場合には、スイッチ２３をＯＦＦにする。この状態で、振動部材１０を往復運動させている場合には、コイル３に発生した電流を整流回路８を介して、充電回路９に充電を行うことができる。 When the light source 21 does not emit light, the switch 23 is turned off. In this state, when the vibration member 10 is reciprocated, the current generated in the coil 3 can be charged to the charging circuit 9 via the rectifier circuit 8.
　以上説明したように、本実施の形態の照明器具２０は、実施の形態１の振動ダイナモ装置１と、筐体５内に組み込まれた回路（本実施の形態では整流回路８および充電回路９）と、筐体５に取り付けられた光源２１及び取手２２とを備えている。 As described above, the lighting fixture 20 of the present embodiment includes the vibration dynamo device 1 of the first embodiment and the circuit incorporated in the housing 5 (the rectifier circuit 8 and the charging circuit 9 in the present embodiment). And a light source 21 and a handle 22 attached to the housing 5.
　これにより、振動部材１０が筒状部材２内で往復運動する際に、振動部材１０において両端に位置する球体が筒状部材２に接するので、振動部材１０と筒状部材２とは点接触となる。振動部材１０に生じる運動エネルギーは接触抵抗を低減できるので、振動部材１０の運動エネルギーからコイル３による電気エネルギーへの変換を向上できる。したがって、発電効率を向上した振動ダイナモ装置１を備える照明器具２０は、発電効率を向上できる。 Thereby, when the vibration member 10 reciprocates in the cylindrical member 2, the spheres located at both ends of the vibration member 10 come into contact with the cylindrical member 2, so that the vibration member 10 and the cylindrical member 2 are in point contact. Become. Since the kinetic energy generated in the vibration member 10 can reduce the contact resistance, the conversion from the kinetic energy of the vibration member 10 to electrical energy by the coil 3 can be improved. Therefore, the lighting fixture 20 provided with the vibration dynamo device 1 with improved power generation efficiency can improve power generation efficiency.

　続いて、図９～図１１を参照して、本実施の形態の照明器具３０の動作について説明する。 Subsequently, the operation of the lighting fixture 30 of the present embodiment will be described with reference to FIGS.
　まず、照明器具３０の保護部材３１を把持して、筒状部材２の延在方向、すなわち図１０における矢印Ａに沿って往復運動する。これにより、実施の形態１と同様に、筒状部材２の内部において、振動部材１０は、筒状部材２の延在方向に沿って往復運動するので、振動部材１０のマグネットから発生する磁束線がコイル３に直交することで、コイル３には交流電流が発生する。コイル３に発生した交流電流は、整流回路８に伝達されて整流され、充電回路９によって充電され、さらに光源２１に伝達されて、発光する。 First, the protective member 31 of the luminaire 30 is gripped and reciprocated along the extending direction of the cylindrical member 2, that is, the arrow A in FIG. Thus, as in the first embodiment, the vibrating member 10 reciprocates along the extending direction of the cylindrical member 2 inside the cylindrical member 2, so that the magnetic flux lines generated from the magnet of the vibrating member 10 Is orthogonal to the coil 3, an alternating current is generated in the coil 3. The alternating current generated in the coil 3 is transmitted to the rectifier circuit 8 to be rectified, charged by the charging circuit 9, and further transmitted to the light source 21 to emit light.
　以上説明したように、本実施の形態の照明器具３０は、実施の形態１の振動ダイナモ装置１と、筐体５内に組み込まれた回路（本実施の形態では整流回路８及び充電回路９）と、筐体５に取り付けられた光源２１とを備えている。 As described above, the lighting fixture 30 of the present embodiment includes the vibration dynamo device 1 of the first embodiment and the circuit incorporated in the housing 5 (the rectifier circuit 8 and the charging circuit 9 in the present embodiment). And a light source 21 attached to the housing 5.
　振動部材１０が筒状部材２内で往復運動する際に、振動部材１０において両端に位置する球体が筒状部材２に接するので、振動部材１０と筒状部材２とは点接触となる。振動部材１０に生じる運動エネルギーは接触抵抗を低減できるので、振動部材１０の運動エネルギーからコイル３による電気エネルギーへの変換を向上できる。したがって、発電効率を向上した振動ダイナモ装置１を備える照明器具３０は、発電効率を向上できる。 When the vibrating member 10 reciprocates within the cylindrical member 2, the spheres located at both ends of the vibrating member 10 are in contact with the cylindrical member 2, so that the vibrating member 10 and the cylindrical member 2 are in point contact.

　（実施の形態４）
　図１２及び図１３を参照して、本実施の形態の照明器具４０は、基本的には実施の形態３と同様であるが、光源２１が筐体５の一方端部にのみ取り付けられている点、及び、支持部材３２が省略されている点において実施の形態３と異なる。 (Embodiment 4)
With reference to FIG.12 and FIG.13, although the lighting fixture 40 of this Embodiment is the same as that of Embodiment 3, the light source 21 is attached only to the one end part of the housing | casing 5.

　自転車の走行時、ペダル５１に加えられた運動エネルギーによって、クランク５２が回転するので、照明器具４０の筒状部材２の延在方向に沿って振動部材１０が往復運動する。これにより、実施の形態３と同様に、振動部材１０のマグネットから発生する磁束線がコイル３に直交することで、コイル３には交流電流が発生する。コイル３に発生した交流電流は、整流回路８に伝達されて整流され、充電回路９によって充電され、さらに光源２１に伝達されて、発光する。自転車を走行していない時には、ペダルを回転させないので、光源２１に電流が流れないので、発光しない。 Since the crank 52 is rotated by the kinetic energy applied to the pedal 51 when the bicycle is running, the vibrating member 10 reciprocates along the extending direction of the tubular member 2 of the lighting device 40. Thus, as in the third embodiment, the magnetic flux lines generated from the magnet of the vibrating member 10 are orthogonal to the coil 3, whereby an alternating current is generated in the coil 3. The alternating current generated in the coil 3 is transmitted to the rectifier circuit 8 to be rectified, charged by the charging circuit 9, and further transmitted to the light source 21 to emit light. When the bicycle is not running, the pedal is not rotated, so that no current flows through the light source 21, and therefore no light is emitted.
