ている。 As a conventional vibration generator of this kind, there is one as shown in FIG. A movable coil 7 as a conductive movable member that receives alternating current from 5 through a lead wire 6 is inserted, and this movable coil 7 is connected to a diaphragm 9 supported by a spring 8. .
なお、振動板9は、ガイド機構10によつて図

いる。 Note that the diaphragm 9 can be smoothly vibrated in the vertical direction in the figure by a guide mechanism 10.
しかしながら、このような従来の振動発生装置

It is also conceivable to form an alternating magnetic field in the gap 4 and generate an induced alternating current in the conductive movable member 7' by electromagnetic induction phenomenon, thereby vibrating the diaphragm 9. Although the number of breakage accidents of the lead wire 6' is drastically reduced, the following problems occur. That is, when high-frequency vibration is performed, the induced alternating current concentrates on the surface of the movable member 7' due to the skin effect, which increases the impedance seen from the fixed coil 11 side, causing heat generation and other causes. , there is a problem that it is difficult to increase the vibration power.
本考案は、これらの問題点を解決しようとする

Multiple annular shapes = Annular shapes closer to the center of the spaces
A magnetic path between the two is formed to be thicker than a magnetic path between the outer annular grooves, and a magnetic path between each of the movable members is formed to be thicker than the magnetic path between the outer annular grooves so as to generate an induced alternating current in each of the movable members and vibrate the vibrating member. It is characterized by being configured with a plurality of fixed coils provided and a power source capable of supplying alternating current in synchronization with each of the plurality of fixed coils.

その概略構成を示す模式図であり、第4図はその
変形例の要部構成を示す模式図であつて、第3,
4図中、第1,2図と同じ符号はほぼ同様の部分
を示している。 Hereinafter, an induced vibration generator as an embodiment of the present invention will be explained with reference to the drawings. FIG. 3 is a schematic diagram showing its general configuration, and FIG. 4 is a schematic diagram showing the main part configuration of a modification thereof. And the third,
In FIG. 4, the same reference numerals as in FIGS. 1 and 2 indicate substantially similar parts.
第3図に示すように、ポールピース3を中央部
に有し、その囲りに第1の円環状隙間41を形成
するように中間磁極部21を有し、更にその囲り

隙間42を形成するようにヨーク部2を有し、こ
れらの部材2,3,12で磁気回路を形成すべく
構成された、励磁コイル1付きの磁場形成機構M
が設けられている。 As shown in FIG. 3, it has a pole piece 3 in the center, an intermediate magnetic pole part 21 to form a first annular gap 41 around the pole piece 3, and a first annular gap 41 around the pole piece 3. It has a yoke part 2 so as to form a second annular gap 42 coaxially with the annular gap 41, and is equipped with an excitation coil 1 configured to form a magnetic circuit with these members 2, 3, and 12. magnetic field formation mechanism M
is provided.
そして、励磁コイル1へは、直流電流が供給さ

2の円環状隙間41,42にそれぞれ直流磁場が
形成される。 A DC current is supplied to the exciting coil 1, thereby forming DC magnetic fields in the first and second annular gaps 41 and 42, respectively.
なお、各隙間41,42は、装置の大型化を招
かないように、従来の隙間4よりも狭く設定され
ているが、隙間41,42および中間磁極部12
の幅をあわせた長さ(ポールピース3からヨーク

も太く形成しており、これにより複数の円環状〓
間があつても磁束が弱くなることを防止してい
る。 Note that the gaps 41 and 42 are set narrower than the conventional gap 4 so as not to increase the size of the device, but the gaps 41 and 42 and the intermediate magnetic pole part 12
Since the combined length of the width (the length from the pole piece 3 to the yoke part 2) becomes a little longer, there is a possibility that the magnetic field becomes weaker. Therefore, as shown in FIG. 3, the magnetic path between the pole piece 3 and the intermediate magnetic pole part 12, that is, the magnetic path in the annular space 41 near the center, is replaced by the magnetic path in the annular space 42 on the outside. It is formed thicker than the cylindrical shape, which creates multiple annular shapes.
This prevents the magnetic flux from weakening even if there is a gap.
また、第1および第2の円環状隙間41,42
には、相互に同軸的に配設される導電性可動部材
としての銅またはアルミニウムなどの導電材料か

いる。 In addition, the first and second annular gaps 41, 42
, thin-walled first and second cylindrical bodies 71 made of a conductive material such as copper or aluminum are arranged coaxially with each other and serve as conductive movable members.
These cylindrical bodies 71 and 72 have their upper ends connected to a single diaphragm (vibrating member) 9 via a common insulating member 13.
そして、この振動板9は、ばね8を介してポー
ルピース3の上面に図中上下方向へ振動可能に支

なお、振動板9は、上下方向の振動が円滑に行
なえるように、ガイド機構10によつて案内され
ている。 Note that the diaphragm 9 is guided by a guide mechanism 10 so that vibration in the vertical direction can be performed smoothly.
ところで、円環状〓間41,42において、ポ
ールピース3の外周面、中間磁極部12およびヨ
ーク部2の内周面には、それぞれ固定コイル1
1,11,11が固着されており、各固定コイル
11へは、リード線6″,6″,6″を通じて外部
の電源5″から相互に同期する交流電流が供給さ
れるようになつている。これにより各隙間41,
42に同期した交流磁場を直流磁場に重ねて形成
することができる。 By the way, in the annular spaces 41 and 42, fixed coils 1 are provided on the outer circumferential surface of the pole piece 3, the inner circumferential surfaces of the intermediate magnetic pole part 12, and the yoke part 2, respectively.
1, 11, and 11 are fixedly fixed, and mutually synchronized alternating current is supplied to each fixed coil 11 from an external power source 5'' through lead wires 6'', 6'', and 6''. . As a result, each gap 41,
An alternating current magnetic field synchronized with 42 can be formed superimposed on a direct current magnetic field.
上述の構成により、各固定コイル11に同期し
た交流電流を流すと、各隙間41,42に同期し
た交流磁場が形成され、これにより円筒体71,
72にそれぞれ同期した交流電圧が誘起されて、
各円筒体71,72に交流電流が流れる。そし
て、これらの交流電流が隙間41,42の磁束と
それぞれ鎖交するため、円筒体71,72に電磁
力が発生し、これにより両円筒体71,72が上
記の各交流電流と同じ周期で振動するため、両円
筒体71,72からの力が加算されて、大きなパ
ワーで振動板9が振動する。 With the above-described configuration, when a synchronized alternating current is applied to each fixed coil 11, a synchronized alternating current magnetic field is formed in each gap 41, 42, which causes the cylindrical body 71,
72, respectively synchronized alternating current voltages are induced,
An alternating current flows through each cylindrical body 71, 72. Since these alternating currents interlink with the magnetic flux in the gaps 41 and 42, electromagnetic force is generated in the cylindrical bodies 71 and 72, which causes both cylindrical bodies 71 and 72 to move at the same period as each of the above-mentioned alternating currents. To vibrate, the forces from both cylindrical bodies 71 and 72 are added, and the diaphragm 9 vibrates with a large power.
このように、固定コイル11には、交流電流供
給用のリード線6″は必要であるが、導電性可動
部材としての円筒体71,72には、交流電流供
給用のリード線が不要であるので、リード線切断
の危険性を大幅に減少させることができ、これに
より保守が簡単で寿命の長い装置を実現しうる。 In this way, the fixed coil 11 requires the lead wire 6'' for supplying alternating current, but the cylindrical bodies 71 and 72 as conductive movable members do not require lead wires for supplying alternating current. Therefore, the risk of lead wire breakage can be significantly reduced, thereby realizing a device that is easy to maintain and has a long life.
また、各円筒体71,72を薄く形成して、こ

嵌挿しているので、装置の大型化を招くことな

ピーダンスを小さくしておくことができ、熱損等
の減少をはかることができる。 Furthermore, since each of the cylindrical bodies 71 and 72 is formed thin and fitted into the narrow gaps 41 and 42, even when high frequency vibration is performed without increasing the size of the device, Impedance can be kept smaller than in the past, and heat loss etc. can be reduced.
さらに、各円筒体71,72による電磁力の総
和で振動板9を加振することができるので、大き
なパワーを得ることができる。 Furthermore, since the diaphragm 9 can be vibrated by the sum of the electromagnetic forces generated by the respective cylindrical bodies 71 and 72, a large amount of power can be obtained.
なお、第3図に示すように、隙間を2つ形成し
て、各隙間41,42に円筒体71,72を嵌挿
する代わりに、隙間を3つ(第4図参照)あるい
はそれ以上形成して、各隙間41,42,43,
…に円筒体71,72,73,…を嵌挿すること
もできる。 Note that instead of forming two gaps and inserting the cylindrical bodies 71 and 72 into each gap 41 and 42 as shown in FIG. 3, three gaps (see FIG. 4) or more may be formed. Then, each gap 41, 42, 43,
It is also possible to fit the cylindrical bodies 71, 72, 73, etc. into...
この場合、隙間の数に応じて、これらの隙間を
形成すべく、中間磁極部12の数も増設される

束が弱くなるのを防止することができる。 In this case, the number of intermediate magnetic pole parts 12 is increased according to the number of gaps in order to form these gaps, but in this case as well, the pole piece 3 and the intermediate magnetic pole part 12 are In other words, the magnetic path between the annular spaces 42 and 43 closer to the center is formed to be thicker than the magnetic path between the annular spaces 41 on the outside. Thereby, it is possible to prevent the magnetic flux from becoming weak even if there are a plurality of annular gaps.
また、導電性可動部材として、銅またはアルミ

場合、巻線を支持体に埋め込むようにすれば、全
体の肉厚を薄くできる。 Furthermore, cylindrical bodies 71, 72, 73, . . . made of copper or aluminum are used as conductive movable members.
Instead of using a cylindrical support, a one-turn loop wire or a plurality of windings may be used. In this case, the overall thickness can be reduced by embedding the winding in the support.
さらに、固定コイル11は、通常空冷に付され
