The vibration dynamo device 2 includes a tubular member 20, a coil 31 disposed on the outer periphery of the tubular member, an elastic body 40, a first vibration member 51, and a second vibration member 52. A closing member 24 is disposed at the lower end of the cylindrical member 20. The closing member 24 may be a repulsion member or an elastic member, for example.

筒状部材２０は、上下方向に延び、後述する内部空間２２，２３を有する。なお、筒状部材２０の外形状および内形状（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。また、本実施の形態の筒状部材２０の内径（中空形状の直径）は、後述する第１振動部材５１の外径よりもやや大きい。   The cylindrical member 20 extends in the vertical direction and has internal spaces 22 and 23 described later. In addition, the outer shape and inner shape (hollow shape) of the cylindrical member 20 are not specifically limited, A circular shape, a rectangular shape, etc. are mentioned in cross-sectional view. In addition, the inner diameter (hollow diameter) of the cylindrical member 20 of the present embodiment is slightly larger than the outer diameter of the first vibrating member 51 described later.

筒状部材２０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、反磁性体およ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 20 is made of a nonmagnetic material. The nonmagnetic 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.

筒状部材２０は、上下に２つ設けられる。具体的には、筒状部材２０は、下方に位置する下筒状部材２１と、上方に位置する上筒状部材２５とを含む。下筒状部材２１と上筒状部材２５の外形状は、断面視において円柱形状（円柱体）であり、その幅方向（たとえば紙面左右方向）長さは、略同一である。具体的には、下筒状部材２１は、大きさの異なる内部空間２２，２３を有する。内部空間２２は、上方に開放する大空間であり、内部空間２３は、内部空間（大空間）２２の下方に位置し、内部空間（大空間）２２よりも内径が小さい小空間である。上筒状部材２５もまた、内部空間２６を有する。内部空間２６は、下筒状部材２１の内部空間（大空間）２２と同じ大きさである。   Two cylindrical members 20 are provided on the upper and lower sides. Specifically, the cylindrical member 20 includes a lower cylindrical member 21 positioned below and an upper cylindrical member 25 positioned above. The outer shape of the lower cylindrical member 21 and the upper cylindrical member 25 is a cylindrical shape (cylindrical body) in a cross-sectional view, and the width direction (for example, the right and left direction in the drawing) is substantially the same. Specifically, the lower cylindrical member 21 has internal spaces 22 and 23 having different sizes. The internal space 22 is a large space that opens upward, and the internal space 23 is a small space that is positioned below the internal space (large space) 22 and has an inner diameter smaller than that of the internal space (large space) 22. The upper tubular member 25 also has an internal space 26. The internal space 26 is the same size as the internal space (large space) 22 of the lower cylindrical member 21.

下筒状部材２１は、上端が開放しており、下端が上述した閉塞部材２４により閉塞されている。また、上筒状部材２５は、上端および下端が開放している。上筒状部材２５の上端は、上述した押ボタン１４の下端に接している。下筒状部材２１の上端と上筒状部材２５の下端との間には、弾性体４０が設けられている。   The lower cylindrical member 21 has an open upper end and is closed by the closing member 24 described above. Further, the upper cylindrical member 25 is open at the upper end and the lower end. The upper end of the upper cylindrical member 25 is in contact with the lower end of the push button 14 described above. An elastic body 40 is provided between the upper end of the lower cylindrical member 21 and the lower end of the upper cylindrical member 25.

弾性体４０は、筒状部材２０に沿って上下方向に弾性的に振動可能である。図２を特に参照して、弾性体４０は、板状のゴムであり、たとえばオゾン劣化等を考慮して、シリコンゴム等の合成ゴムであることが好ましい。弾性体４０は、第１，２振動部材５１，５２の外形の大きさによって異なるが、薄い方が好ましく、その厚みは、たとえば、０．０８ｍｍ以上であり、たとえば、２ｍｍ以下、好ましくは０．８ｍｍ以下である。また、弾性体４０の硬度は、デュロメータＡ硬度で９０°以下であることが好ましい。また、弾性体４０の外形は、平面視略円形状である。弾性体４０は、外縁部４３と、筒状部材２０の内部空間２２，２６に位置する中央部４１とを有する。具体的には、外縁部４３は、下筒状部材２１と上筒状部材２５との間に挟まれている。これにより、弾性体４０は、筒状部材２０に支持される。   The elastic body 40 can elastically vibrate in the vertical direction along the cylindrical member 20. With particular reference to FIG. 2, the elastic body 40 is a plate-like rubber, and is preferably a synthetic rubber such as silicon rubber in consideration of, for example, ozone deterioration. The elastic body 40 differs depending on the size of the outer shape of the first and second vibrating members 51 and 52, but is preferably thinner. The thickness is, for example, 0.08 mm or more, for example, 2 mm or less, preferably 0. 8 mm or less. The hardness of the elastic body 40 is preferably 90 ° or less in terms of durometer A hardness. Further, the outer shape of the elastic body 40 is substantially circular in plan view. The elastic body 40 has an outer edge portion 43 and a central portion 41 located in the inner spaces 22 and 26 of the tubular member 20. Specifically, the outer edge portion 43 is sandwiched between the lower cylindrical member 21 and the upper cylindrical member 25. Thereby, the elastic body 40 is supported by the cylindrical member 20.

外縁部４３と中央部４１との間には、リング状の隙間が設けられ、その隙間には、外縁部４３と中央部４１とを連結する連結部４２が複数設けられている。これにより、外縁部４３と中央部４１との間には、たとえば６つの貫通穴４４が設けられる。複数の貫通穴４４および連結部４２が設けられることで、弾性体４０は、撓みやすくなり、上下に振動しやくなる。なお、外縁部４３には、外周に沿って複数の穴部４５が設けられていてもよい。下筒状部材２１の上端に設けられる突起（図示せず）が穴部４５を貫通し、上筒状部材２５の下端に設けられる凹部（図示せず）に係合することで、弾性体４０を筒状部材２０に固定することができる。   A ring-shaped gap is provided between the outer edge portion 43 and the central portion 41, and a plurality of connecting portions 42 that connect the outer edge portion 43 and the central portion 41 are provided in the gap. Accordingly, for example, six through holes 44 are provided between the outer edge portion 43 and the central portion 41. By providing the plurality of through holes 44 and the connecting portion 42, the elastic body 40 is easily bent and easily vibrates up and down. The outer edge 43 may be provided with a plurality of holes 45 along the outer periphery. A protrusion (not shown) provided at the upper end of the lower cylindrical member 21 passes through the hole 45 and engages with a recess (not shown) provided at the lower end of the upper cylindrical member 25, whereby the elastic body 40. Can be fixed to the cylindrical member 20.

この下筒状部材２１の外周には、コイル３１が巻回されている。このため、下筒状部材２１は、コイル３１のボビンの役割も担う。本実施の形態のコイル３１は、下筒状部材２１の外周の一部に設けられている。具体的には、コイル３１は、下筒状部材２１の上下方向の略中央部に取り付けられる。コイル３１は、たとえば、ソレノイドコイルである。なお、コイル３１は、下筒状部材２１の全周に設けられていてもよい。   A coil 31 is wound around the outer periphery of the lower cylindrical member 21. For this reason, the lower cylindrical member 21 also serves as a bobbin for the coil 31. The coil 31 of the present embodiment is provided on a part of the outer periphery of the lower cylindrical member 21. Specifically, the coil 31 is attached to a substantially central portion in the vertical direction of the lower cylindrical member 21. The coil 31 is, for example, a solenoid coil. The coil 31 may be provided on the entire circumference of the lower cylindrical member 21.

筒状部材２０の内部には、筒状部材２０の延在方向（図１における矢印Ａの上下方向）に沿って移動可能な状態で、第１振動部材５１および第２振動部材５２が設けられている。第１振動部材５１および５第２振動部材５２は、弾性体４０の中央部４１を上下から挟むように配置され、磁力によって互いに吸引保持される。これにより、第１振動部材５１および第２振動部材５２は、弾性体４０に保持され、弾性体４０と共に移動する。下筒状部材２１は、内部空間２２，２３に第１振動部材５１を配置し、上筒状部材２５は、内部空間２６に第２振動部材５２を配置する。   A first vibrating member 51 and a second vibrating member 52 are provided inside the cylindrical member 20 in a state that it can move along the extending direction of the cylindrical member 20 (the vertical direction of the arrow A in FIG. 1). ing. The first vibrating member 51 and the fifth second vibrating member 52 are arranged so as to sandwich the central portion 41 of the elastic body 40 from above and below, and are attracted and held by magnetic force. Thereby, the first vibrating member 51 and the second vibrating member 52 are held by the elastic body 40 and move together with the elastic body 40. The lower cylindrical member 21 arranges the first vibrating member 51 in the internal spaces 22 and 23, and the upper cylindrical member 25 arranges the second vibrating member 52 in the internal space 26.

本実施の形態の第１振動部材５１は、永久磁石であり、半球状のＮ極とＳ極となるように着磁されている。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、永久磁石は、保磁力を有する硬磁性材料を含む磁性体である。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。第１振動部材５１は、球体である。なお、球体とは、外形が球状であることを意味し、内部が空洞であるものを含む。   The first vibrating member 51 of the present embodiment is a permanent magnet and is magnetized so as to have a hemispherical N pole and S pole. 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 permanent magnet is a magnetic body including a hard magnetic material having a coercive force. 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. The first vibrating member 51 is a sphere. Note that the sphere means that the outer shape is spherical, and includes a hollow inside.

本実施の形態の第２振動部材５２は、ヨーク（継鉄）であり、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、軟磁性材料を含む磁性体である。したがって、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。第２振動部材５２は、球体であり、第１振動部材５１よりも外径が小さい。ここでいう球体もまた、外形が球状であることを意味し、内部が空洞であるものを含む。   The second vibrating member 52 of the present embodiment is a yoke (a yoke), is soft iron that amplifies the attractive force of the magnet, and may contain iron, and is a magnetic body containing a soft magnetic material. Therefore, in this embodiment, a steel ball is used as the spherical yoke. The second vibrating member 52 is a sphere and has an outer diameter smaller than that of the first vibrating member 51. The sphere here also means that the outer shape is spherical, and includes a hollow inside.

上述のように、下筒状部材２１の外周には、コイル３１が配置されている。押ボタン１４を押して手を離すと、振動ダイナモ装置２が下方に移動し、弾性体４０が小刻みに上下に振動（バウンド）を繰り返す。これにより、第１，２振動部材５１，５２は、下筒状部材２１の内部空間２２，２３において、筒状部材２０の延在方向に沿って同時に往復運動する。第１振動部材５１は、下筒状部材２１の外周に配置されたコイル３１内を通過するような往復運動をすることになるので、第１振動部材５１から発生する磁束線がコイル３１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。第１振動部材５１がコイル３１内の出入りを繰り返すので、コイル３１には交流電流が発生する。   As described above, the coil 31 is disposed on the outer periphery of the lower cylindrical member 21. When the push button 14 is pushed and released, the vibration dynamo device 2 moves downward, and the elastic body 40 repeatedly vibrates up and down (bound) in small increments. Accordingly, the first and second vibrating members 51 and 52 reciprocate simultaneously along the extending direction of the tubular member 20 in the internal spaces 22 and 23 of the lower tubular member 21. Since the first vibrating member 51 reciprocates so as to pass through the coil 31 disposed on the outer periphery of the lower cylindrical member 21, the magnetic flux lines generated from the first vibrating member 51 are orthogonal to the coil 31. At that time, an induced current is generated as an induced electromotive force. Since the first vibrating member 51 repeats entering and exiting the coil 31, an alternating current is generated in the coil 31.

図３は、チャイム装置１の等価回路図である。図３を参照して、チャイム装置１は、上述の振動ダイナモ装置２と、整流回路６１と、充電回路６２と、音発生装置６３と、スイッチ６４とを備えている。これらは全て、図１で示す筐体１０内に収容されている。   FIG. 3 is an equivalent circuit diagram of the chime device 1. Referring to FIG. 3, the chime device 1 includes the above-described vibration dynamo device 2, a rectifier circuit 61, a charging circuit 62, a sound generator 63, and a switch 64. All of these are housed in a housing 10 shown in FIG.

整流回路６１は、コイル３１（図１）の一端に設けられ、コイル３１に発生した交流電流を整流する。充電回路６２は、整流回路６１により変換された直流電流を充電する。充電回路６２には、たとえば電気二重層コンデンサが用いられる。音発生装置６３は、電流が印加されたときに音を発するものであれば特に限定されず、たとえばブザー、鈴音、音楽などを用いることができる。   The rectifier circuit 61 is provided at one end of the coil 31 (FIG. 1) and rectifies the alternating current generated in the coil 31. The charging circuit 62 charges the direct current converted by the rectifying circuit 61. For the charging circuit 62, for example, an electric double layer capacitor is used. The sound generator 63 is not particularly limited as long as it emits a sound when a current is applied. For example, a buzzer, a bell, music, or the like can be used.

スイッチ６４は、ユーザにより操作され、音発生装置６３の導通／非導通を切り替える。スイッチがＯＦＦの状態で押ボタン１４（図１）を押圧した場合、振動ダイナモ装置２で発生した電流は充電回路６２に蓄えられる。そのため、本実施の形態によれば、充電回路６２が充電されていれば、押ボタン１４を押圧しなくても、スイッチ６４をＯＮにすることで音発生装置６３を鳴らすことができる。   The switch 64 is operated by the user to switch between conduction / non-conduction of the sound generator 63. When the push button 14 (FIG. 1) is pressed while the switch is OFF, the current generated by the vibration dynamo device 2 is stored in the charging circuit 62. Therefore, according to the present embodiment, if the charging circuit 62 is charged, the sound generator 63 can be sounded by turning on the switch 64 without pressing the push button 14.

続いて、図１，図４を参照して、本実施の形態のチャイム装置１の動作について説明する。   Then, with reference to FIG. 1, FIG. 4, operation | movement of the chime apparatus 1 of this Embodiment is demonstrated.

まず、スイッチ６４（図３）をＯＮにして導通状態にする。チャイム装置１の押ボタン１４を下方に押圧すると、図４（ａ）に示すように、バネ部材１５の付勢力に反して、振動ダイナモ装置２も下方に移動する。これにより、筒状部材２０の内部空間２２，２３，２６において、第１，２振動部材５１，５２が下方に移動し、それに伴って弾性体４０も下方に伸びる。そして、図４（ｂ）に示すように、押ボタン１４から手を離すと、バネ部材１５の付勢力に伴って、振動ダイナモ装置２も上方に移動する。   First, the switch 64 (FIG. 3) is turned on to make it conductive. When the push button 14 of the chime device 1 is pressed downward, the vibration dynamo device 2 also moves downward against the urging force of the spring member 15 as shown in FIG. Thereby, in the internal spaces 22, 23, and 26 of the cylindrical member 20, the first and second vibrating members 51 and 52 move downward, and accordingly, the elastic body 40 also extends downward. Then, as shown in FIG. 4B, when the hand is released from the push button 14, the vibration dynamo device 2 also moves upward along with the urging force of the spring member 15.

これにより、筒状部材２０の内部空間２２，２３，２６において、第１振動部材５１および第２振動部材５２が上方に移動し、それに伴って弾性体４０も上方に移動する。さらに、弾性体４０は、バネ部材１５の上下の振動に伴って上下に振動し、第１振動部材５１および第２振動部材５２も筒状部材２０の延在方向に沿って上下に往復運動する。第１振動部材５１は下筒状部材２１の外周に配置されたコイル３１内を通過するような往復運動をすることになるので、第１振動部材５１から発生する磁束線がコイル３１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。第１振動部材５１がコイル３１内の出入りを繰り返すので、コイル３１には交流電流が発生する。   Thereby, in the internal spaces 22, 23, and 26 of the cylindrical member 20, the 1st vibration member 51 and the 2nd vibration member 52 move upwards, and the elastic body 40 also moves upwards in connection with it. Further, the elastic body 40 vibrates up and down with the vertical vibration of the spring member 15, and the first vibration member 51 and the second vibration member 52 also reciprocate up and down along the extending direction of the tubular member 20. . Since the first vibrating member 51 reciprocates so as to pass through the coil 31 disposed on the outer periphery of the lower cylindrical member 21, the magnetic flux lines generated from the first vibrating member 51 are orthogonal to the coil 31. At that time, an induced current is generated as an induced electromotive force. Since the first vibrating member 51 repeats entering and exiting the coil 31, an alternating current is generated in the coil 31.

なお、図１，３に示すように、振動ダイナモ装置２のコイル３１に発生した交流電流は、コイル３１の両端に接続された配線（図示せず）を介して整流回路６１に伝達される。整流回路６１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、充電回路６２によって充電される。充電された電流は、スイッチ６４を介して音発生装置６３に伝達される。音発生装置６３は供給された電流によって駆動（稼働）する。このようにして、ユーザは、チャイム装置１を使用することができる。   As shown in FIGS. 1 and 3, the alternating current generated in the coil 31 of the vibration dynamo device 2 is transmitted to the rectifier circuit 61 via wires (not shown) connected to both ends of the coil 31. Full-wave rectification is performed by the rectifier circuit 61 to rectify an alternating current into a DC power source, and the charging circuit 62 charges the battery. The charged current is transmitted to the sound generator 63 via the switch 64. The sound generator 63 is driven (operated) by the supplied current. In this way, the user can use the chime device 1.

本実施の形態のチャイム装置１では、コイル３１内を往復運動する第１振動部材５１を弾性体４０で上下方向に振動可能に支持するため、簡易な構造で発電することができる。   In the chime device 1 according to the present embodiment, since the first vibrating member 51 that reciprocates in the coil 31 is supported by the elastic body 40 so as to vibrate in the vertical direction, power can be generated with a simple structure.

また、弾性体４０は、上下に振動すると、図４に示すように、伸縮運動して弾性変形を繰り返すことになる。この場合、第１，２振動部材５１，５２がいずれも球体であるため、弾性体４０を第１振動部材５１および第２振動部材５２で上下から挟んだ場合、第１，２振動部材５１，５２は、弾性体４０を介して第１，２振動部材５１，５２の外周の幅方向中央部の一点で強く吸引される。これにより、第１振動部材５１および第２振動部材５２は、弾性体４０の弾性変形を阻害しないため、弾性体４０は、効率よく上下の振動を繰り返すことが可能となる。   Further, when the elastic body 40 vibrates up and down, as shown in FIG. 4, the elastic body 40 expands and contracts and repeats elastic deformation. In this case, since both the first and second vibrating members 51 and 52 are spherical bodies, when the elastic body 40 is sandwiched from above and below by the first vibrating member 51 and the second vibrating member 52, the first and second vibrating members 51, 52 is strongly sucked through the elastic body 40 at one point in the center in the width direction of the outer periphery of the first and second vibrating members 51 and 52. Thereby, since the 1st vibration member 51 and the 2nd vibration member 52 do not inhibit elastic deformation of elastic body 40, elastic body 40 can repeat an up-and-down vibration efficiently.

以下の実施の形態では、チャイム装置１の他の構成例について説明する。以下に実施の形態１との相違点のみ詳細に説明する。   In the following embodiment, another configuration example of the chime device 1 will be described. Only differences from the first embodiment will be described in detail below.

＜実施の形態２＞
上記実施の形態１の振動ダイナモ装置２は、第１振動部材５１および第２振動部材５２はいずれも球体であったが、本実施の形態では、第１振動部材５１Ａの形状が異なっている。その他の構成は、実施の形態１と同様の構成であってよい。 <Embodiment 2>
In the vibration dynamo device 2 of the first embodiment, the first vibration member 51 and the second vibration member 52 are both spheres, but in the present embodiment, the shape of the first vibration member 51A is different. Other configurations may be the same as those in the first embodiment.

図５を参照して、本実施の形態では、第１振動部材５１Ａは永久磁石であり、形状が円柱体である。なお、円柱体とは、外形が円柱状であることを意味し、内部が空洞であるものを含む。   With reference to FIG. 5, in the present embodiment, first vibration member 51 </ b> A is a permanent magnet and has a cylindrical shape. In addition, a cylindrical body means that an external shape is a column shape, and the inside has a cavity.

この場合、第１振動部材５１Ａが円柱体、第２振動部材５２が球体であるため、弾性体４０を第１，２振動部材５１Ａ，５２で上下から挟んだ場合、第１，２振動部材５１Ａ，５２は、弾性体４０を介して、第１振動部材５１Ａの平面部分の幅方向中央部の一点、および、第２振動部材５２の外周の幅方向中央部の一点で強く吸引される。これにより、第１振動部材５１Ａおよび第２振動部材５２は、弾性体４０の弾性変形を阻害せず、弾性体４０は、効率よく振動を繰り返すことが可能となる。   In this case, since the first vibration member 51A is a cylindrical body and the second vibration member 52 is a sphere, when the elastic body 40 is sandwiched from above and below by the first and second vibration members 51A, 52, the first and second vibration members 51A , 52 are strongly attracted via the elastic body 40 at one point in the width direction central portion of the planar portion of the first vibration member 51A and one point in the width direction central portion of the outer periphery of the second vibration member 52. Accordingly, the first vibrating member 51A and the second vibrating member 52 do not hinder the elastic deformation of the elastic body 40, and the elastic body 40 can repeatedly vibrate efficiently.

＜実施の形態３＞
実施の形態１，２では、振動ダイナモ装置２，２Ａは、コイル３１が１つしか設けられていなかったが、上筒状部材２５Ｂに設けられていてもよい。本実施の形態では、上筒状部材２５Ｂ、第２振動部材５２Ｂおよびバネ部材１５Ｂが異なっている。その他の構成は、実施の形態１と同様の構成であってよい。 <Embodiment 3>
In the first and second embodiments, the vibration dynamo devices 2 and 2A are provided with only one coil 31, but may be provided on the upper tubular member 25B. In the present embodiment, the upper cylindrical member 25B, the second vibration member 52B, and the spring member 15B are different. Other configurations may be the same as those in the first embodiment.

図６を参照して、上筒状部材２５Ｂは、下筒状部材２１と同様の構成を備える。具体的には、上筒状部材２５Ｂは、弾性体４０を境界に、上下対称に設けられる。すなわち、上筒状部材２５Ｂは、大きさの異なる内部空間２６Ｂ，２７Ｂを有する。内部空間２６Ｂは、下方に開放する大空間であり、内部空間２７Ｂは、内部空間（大空間）２６Ｂの上方に位置し、内部空間（大空間）２６Ｂよりも小さい小空間である。上筒状部材２５Ｂの上端部には閉塞部材２８Ｂが配置されている。なお、閉塞部材２８Ｂは、たとえば反発部材であってもよいし、弾性部材であってもよい。   With reference to FIG. 6, the upper cylindrical member 25 </ b> B has the same configuration as the lower cylindrical member 21. Specifically, the upper cylindrical member 25B is provided symmetrically with respect to the elastic body 40 as a boundary. That is, the upper cylindrical member 25B has internal spaces 26B and 27B having different sizes. The internal space 26B is a large space that opens downward, and the internal space 27B is located above the internal space (large space) 26B and is a small space that is smaller than the internal space (large space) 26B. A closing member 28B is disposed at the upper end of the upper cylindrical member 25B. The closing member 28B may be, for example, a repulsion member or an elastic member.

この上筒状部材２５Ｂの外周には、コイル３２Ｂが巻回されている。このため、上筒状部材２５Ｂは、コイル３２Ｂのボビンの役割も担う。本実施の形態のコイル３２Ｂは、上筒状部材２５Ｂの外周の一部に設けられている。具体的には、コイル３２Ｂは、上筒状部材２５Ｂの上下方向の略中央部に取り付けられる。コイル３２Ｂは、たとえば、ソレノイドコイルである。なお、コイル３２Ｂは、上筒状部材２５Ｂの全周に設けられていてもよい。   A coil 32B is wound around the outer periphery of the upper cylindrical member 25B. For this reason, the upper cylindrical member 25B also serves as a bobbin for the coil 32B. The coil 32B of the present embodiment is provided on a part of the outer periphery of the upper cylindrical member 25B. Specifically, the coil 32B is attached to a substantially central portion in the vertical direction of the upper cylindrical member 25B. The coil 32B is, for example, a solenoid coil. The coil 32B may be provided on the entire circumference of the upper cylindrical member 25B.

本実施の形態では、第１，２振動部材５１，５２Ｂは、永久磁石であり、形状が球体である。すなわち、本実施の形態の振動ダイナモ装置２Ｂには、球体の永久磁石が２つ設けられる。第１，２振動部材５１，５２Ｂの外形の大きさは、略同一である。   In the present embodiment, the first and second vibrating members 51 and 52B are permanent magnets and have a spherical shape. That is, the spherical dynamo device 2B of the present embodiment is provided with two spherical permanent magnets. The outer sizes of the first and second vibrating members 51 and 52B are substantially the same.

振動ダイナモ装置２Ｂは、上筒状部材２５Ｂと下筒状部材２１とが同様の構成を備え、実施の形態１，２と比較して振動ダイナモ装置２Ｂの上下方向の長さが長くなったため、筐体１０Ｂの側面１１Ｂの上下方向の長さも長くなっている。   In the vibration dynamo device 2B, the upper cylindrical member 25B and the lower cylindrical member 21 have the same configuration, and the vertical length of the vibration dynamo device 2B is longer than in the first and second embodiments. The length of the side surface 11B of the housing 10B in the vertical direction is also long.

バネ部材１５Ｂは、たとえば、輪ばねである。輪ばねは、円すい面を持った内輪と外輪を交互に組み合わせ重ねたばねである。バネ部材１５Ｂの上部は、振動ダイナモ装置２Ｂの上部を固定し、バネ部材１５Ｂの下部は、筐体１０Ｂの底面１３に設けられる。これにより、バネ部材１５Ｂは、振動ダイナモ装置２Ｂを上方に付勢する。バネ部材１５Ｂは、非磁性体である。   The spring member 15B is, for example, a ring spring. The ring spring is a spring in which inner rings and outer rings having a conical surface are alternately combined and stacked. The upper part of the spring member 15B fixes the upper part of the vibration dynamo device 2B, and the lower part of the spring member 15B is provided on the bottom surface 13 of the housing 10B. Accordingly, the spring member 15B biases the vibration dynamo device 2B upward. The spring member 15B is a nonmagnetic material.

この場合、本実施の形態の振動ダイナモ装置２Ｂは、コイル３１，３２Ｂが２つ設けられ、その間を永久磁石の第１，２振動部材５１，５２Ｂが往復運動するため、実施の形態１，２と比較して、発電量を大きくすることができる。また、振動部材５１，５２Ｂがいずれも球体であるため、弾性体４０を第１，２振動部材５１，５２Ｂで上下から挟んだ場合、第１，２振動部材５１，５２Ｂの外周の幅方向中央部の一点で強く吸引される。これにより、第１，２振動部材５１，５２Ｂは、弾性体４０の弾性変形を阻害せず、弾性体４０は、効率よく振動を繰り返すことが可能となる。   In this case, the vibration dynamo device 2B of the present embodiment is provided with two coils 31, 32B, and the first and second vibration members 51, 52B of permanent magnets reciprocate between them. Compared with, power generation can be increased. Further, since the vibration members 51 and 52B are both spherical bodies, when the elastic body 40 is sandwiched from above and below by the first and second vibration members 51 and 52B, the center in the width direction of the outer periphery of the first and second vibration members 51 and 52B. Strong suction at one point. Thereby, the 1st, 2nd vibration members 51 and 52B do not inhibit the elastic deformation of the elastic body 40, and the elastic body 40 can repeat a vibration efficiently.

なお、実施の形態３のチャイム装置１Ｂでは、バネ部材１５Ｂとして輪ばねを用いた。しかし、図７に示すように、チャイム装置１Ｃは、実施の形態１，２と同様に、バネ部材１５としてコイルばねを用いてもよい。その他の構成は、上述した実施の形態３と同様の構成であってよい。   In the chime device 1B of the third embodiment, a ring spring is used as the spring member 15B. However, as shown in FIG. 7, the chime device 1 </ b> C may use a coil spring as the spring member 15 as in the first and second embodiments. Other configurations may be the same as those of the third embodiment described above.

＜実施の形態４＞
上記実施の形態３の変形例では、振動ダイナモ装置２Ｂの第１，２振動部材５１，５２Ｂがいずれも球体であったが、本実施の形態では、第１，２振動部材５１Ａ，５２Ｄの形状が異なっている。その他の構成は、実施の形態３の変形例のチャイム装置１Ｃと同様の構成であってもよい。 <Embodiment 4>
In the modification of the third embodiment, the first and second vibration members 51 and 52B of the vibration dynamo device 2B are both spheres. However, in the present embodiment, the shapes of the first and second vibration members 51A and 52D are used. Is different. Other configurations may be the same as those of the chime device 1C according to the modification of the third embodiment.

図８を参照して、本実施の形態では、第１，２振動部材５１Ａ，５２Ｄは、永久磁石であり、形状が円柱体である。   Referring to FIG. 8, in the present embodiment, first and second vibrating members 51A and 52D are permanent magnets and are cylindrical in shape.

この場合、第１，２振動部材５１Ａ，５２Ｄの形状がいずれも円柱体であるため、弾性体４０を第１，２振動部材５１Ａ，５２Ｄで上下から挟んだ場合、第１，２振動部材５１Ａ，５２Ｄの平面部分、つまり面同士で強く吸引され、吸着力が強くなる。これにより、第１，２振動部材５１Ａ，５２Ｄは、弾性体４０の弾性変形をやや阻害するものの、第１，２振動部材５１Ａ，５２Ｄで確実に上下から挟むことができるため、第１，２振動部材５１Ａ，５２Ｄが弾性体４０から外れるおそれがない。   In this case, since the shapes of the first and second vibrating members 51A and 52D are both cylindrical, when the elastic body 40 is sandwiched from above and below by the first and second vibrating members 51A and 52D, the first and second vibrating members 51A. , 52D, that is, the surfaces are sucked strongly and the attraction force is increased. Thus, although the first and second vibrating members 51A and 52D slightly obstruct the elastic deformation of the elastic body 40, the first and second vibrating members 51A and 52D can be securely sandwiched from above and below by the first and second vibrating members 51A and 52D. There is no possibility that the vibration members 51 </ b> A and 52 </ b> D are detached from the elastic body 40.

＜実施の形態５＞
上記実施の形態４では、振動ダイナモ装置２Ｄは、第１，２振動部材５１Ａ，５２Ｄはいずれも円柱体であったが、本実施の形態では、第２振動部材５２Ｂの形状が異なっている。その他の構成は、実施の形態４と同様の構成であってもよい。 <Embodiment 5>
In the fourth embodiment, in the vibration dynamo device 2D, the first and second vibration members 51A and 52D are both cylindrical, but in the present embodiment, the shape of the second vibration member 52B is different. Other configurations may be the same as those in the fourth embodiment.

図９を参照して、本実施の形態では、第１振動部材５１Ａは、永久磁石であり、形状が円柱体である。第２振動部材５２Ｂは、永久磁石であり、形状が球体である。   Referring to FIG. 9, in the present embodiment, first vibration member 51A is a permanent magnet and has a cylindrical shape. The second vibrating member 52B is a permanent magnet and has a spherical shape.

この場合、第１振動部材５１Ａが円柱体、第２振動部材５２Ｂが球体であるため、弾性体４０を第１，２振動部材５１Ａ，５２Ｂで上下から挟んだ場合、第１振動部材５１Ａの平面の幅方向中央部、および、第２振動部材５２Ｂの外周の幅方向中央部の一点で強く吸引される。これにより、第１，２振動部材５１Ａ，５２Ｂは、弾性体４０の弾性変形を阻害せず、弾性体４０は、効率よく振動を繰り返すことが可能となる。   In this case, since the first vibration member 51A is a cylindrical body and the second vibration member 52B is a sphere, when the elastic body 40 is sandwiched from above and below by the first and second vibration members 51A and 52B, the plane of the first vibration member 51A The central portion in the width direction and the central portion in the width direction of the outer periphery of the second vibrating member 52B are strongly sucked. Accordingly, the first and second vibrating members 51A and 52B do not hinder the elastic deformation of the elastic body 40, and the elastic body 40 can efficiently repeat the vibration.

なお、実施の形態１〜５において、振動ダイナモ装置２〜２Ｅは、チャイム装置１〜１Ｅに用いられるとして説明した。しかし、振動ダイナモ装置２〜２Ｅは、チャイム装置に用いられることに限定されず、たとえば押ボタン、信号発電機など、弾性体４０の振動を利用して発電することができる様々な機器に用いることができる。   In Embodiments 1 to 5, the vibration dynamo devices 2 to 2E are described as being used for the chime devices 1 to 1E. However, the vibration dynamo devices 2 to 2E are not limited to being used in a chime device, and may be used in various devices that can generate electric power using vibrations of the elastic body 40, such as push buttons and signal generators. Can do.

また、実施の形態１，２では、第２振動部材５２は、ヨークであるとして説明したが、永久磁石であってもよい。第２振動部材５２が永久磁石である場合、第１振動部材５１，５１Ａはヨークであってもよい。その場合、ヨークの第１振動部材５１がコイル３１内を往復移動する。また、実施の形態３〜５では、第１振動部材５１，５１Ａおよび第２振動部材５２Ｂ，５２Ｄはいずれも永久磁石であるとして説明したが、一方が永久磁石、他方がヨークであってもよい。実施の形態１〜５の第１振動部材５１，５１Ａおよび第２振動部材５２Ｂ，５２Ｄの外形は、上述した形状に限定されない。   In the first and second embodiments, the second vibrating member 52 is described as a yoke, but may be a permanent magnet. When the second vibration member 52 is a permanent magnet, the first vibration members 51 and 51A may be yokes. In that case, the first vibrating member 51 of the yoke reciprocates in the coil 31. In the third to fifth embodiments, the first vibration member 51, 51A and the second vibration member 52B, 52D are described as being permanent magnets, but one may be a permanent magnet and the other may be a yoke. . The outer shapes of the first vibrating members 51 and 51A and the second vibrating members 52B and 52D in the first to fifth embodiments are not limited to the shapes described above.
