５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。 The induced vibration generator as an embodiment of the present invention will be explained below with reference to the drawings. FIG. 3 is a schematic diagram showing its schematic structure, and FIG. 4 is a partial sectional view showing an enlarged portion of FIG. 3. , FIG. 5 is a partial sectional view showing an enlarged portion of FIG.
In FIG. 5, the same reference numerals as in FIGS. 1 and 2 indicate substantially similar parts.

成る磁場形成機構Ｍが設けられており、これらの
ヨーク部２とポールピース３とで円環状隙間４が
形成されている。したがつて、この隙間４には、
直流磁場が形成される。 As shown in FIG. 3, a magnetic field forming mechanism M is provided which consists of a yoke part 2 with an excitation coil 1 that receives a direct current and a pole piece 3, and the yoke part 2 and pole piece 3 form an annular gap. 4 is formed. Therefore, in this gap 4,
A direct current magnetic field is created.
また、隙間４には、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ら成る円筒
体７′が嵌挿されており、この円筒体７′は、振動
板（振動部材）９に連結されている。 Further, a cylindrical body 7' made of a conductive material such as copper or aluminum is fitted into the gap 4 as a conductive movable member, and this cylindrical body 7' is connected to a diaphragm (vibrating member) 9. ing.
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
持されている。 The diaphragm 9 is supported via a spring 8 on the upper surface of the pole piece 3 so as to be able to vibrate in the vertical direction in the figure.
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、図示しないガイド機構によつて案
内されている。 Note that the diaphragm 9 is guided by a guide mechanism (not shown) so that vibration in the vertical direction can be performed smoothly.
ところで、隙間４の対向する円周面には、それ
ぞれ固定コイル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′を通じて
外部の電源５′から互いに同期する交流電流が供
給されるようになつている。これにより隙間４
に、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, fixed coils 11, 11 are fixed to the opposing circumferential surfaces of the gap 4, respectively, and mutually synchronized alternating current is supplied to each fixed coil 11 from an external power source 5' through lead wires 6', 6'. Current is being supplied. This allows gap 4
Additionally, an alternating current magnetic field can be formed by superimposing a direct current magnetic field.
これにより、固定コイル１１に交流電流を流す
と、隙間４に交流磁場が形成され、その結果円筒
体７′に交流電圧が誘起されて、円筒体７′に交流
電流が流れる。そして、この交流電流が隙間４の
磁束と鎖交するため、円筒体７′に電磁力が発生
し、これにより円筒体７′が上記交流電流と同じ
周期で振動するため、振動板９が振動する。 As a result, when an alternating current is passed through the fixed coil 11, an alternating magnetic field is formed in the gap 4, and as a result, an alternating voltage is induced in the cylindrical body 7', and an alternating current flows through the cylindrical body 7'. Since this alternating current interlinks with the magnetic flux in the gap 4, an electromagnetic force is generated in the cylindrical body 7', which causes the cylindrical body 7' to vibrate at the same period as the alternating current, causing the diaphragm 9 to vibrate. do.
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７′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 a lead wire 6' for supplying alternating current, but the cylindrical body 7' as a conductive movable member does not require a lead wire for supplying alternating current. , the risk of lead wire breakage can be significantly reduced, resulting in a device that is easy to maintain and has a long life.
しかし、このとき隙間４の磁束とほとんど鎖交
しない円筒体７′の上端部に、電流が流れると、
この部分が発熱して、この熱が振動板９へ伝わ

This part generates heat, and this heat is transmitted to the diaphragm 9, which is undesirable.
そこで、円筒体７′の上端部には、第４図に示
すように、絶縁層１２と導体層１３とを交互に積

９へ伝えることができるのである。 As a result, the current generated in the cylindrical body 7' is blocked by the laminated body 10, so that the cylindrical body 7' and the diaphragm 9
The electromagnetic force generated in the cylindrical body 7' can be reliably transmitted to the diaphragm 9 while sufficiently suppressing the heat generation phenomenon at the connecting portion with the cylindrical body 7'.
ところで、円筒体７′の下端部には、第５図に
示すように、絶縁層１７と導体層１８とを交互に
積層した積層体１９がボルト２０で取付けられて

Note that this laminate 19 is provided at a position interlinking with the magnetic flux in the gap 4.
したがつて、この積層体１９の導体層１８の数
を適宜調整すれば、円筒体７′を介して振動板９
へ伝わる力を補正して、決められた正確な起振力
で振動板９を振動させることができる。 Therefore, by appropriately adjusting the number of conductor layers 18 in this laminate 19, the diaphragm 9 can be connected via the cylindrical body 7'.
By correcting the force transmitted to the diaphragm 9, it is possible to vibrate the diaphragm 9 with a predetermined and accurate excitation force.
なお、積層体１０を隙間４の磁束と鎖交する位
置に設けると、この積層体１０によつても起振力

１′がヨーク部２の内周面とポールピース３の外
周面にそれぞれ固着されている。 In this embodiment, in addition to the thin conductor layer 18, there is only one very thick conductor layer 2 at the lower end of the cylinder 7'.
A fixed coil 1 for this laminate 22 is attached with bolts 23.
1' are fixed to the inner circumferential surface of the yoke portion 2 and the outer circumferential surface of the pole piece 3, respectively.

て、振動板９を振動させることができる。 Therefore, if it is desired to obtain a large electromagnetic force, it is sufficient to supply a synchronized alternating current from the external power supply 5'' to the fixed coils 11 and 11' through the lead wires 6' and 6'', thereby causing the cylindrical bodies 7' and The diaphragm 9 can be vibrated by both electromagnetic forces with the laminate 22 including the very thick conductor layer 21.
なお、固定コイル１１にだけ交流電流を供給す
ることもでき、この場合は積層体２２を取り外す
か、前述の実施例のような積層体１９を取り付け
て使用する。 Note that it is also possible to supply alternating current only to the fixed coil 11, and in this case, the laminate 22 is removed or the laminate 19 as in the above-mentioned embodiment is attached and used.
また、前述の各実施例において、円筒体７′を
導体層と絶縁層とを交互に積層したものとして用
