Although the giant magnetostrictive element is certainly useful, its use is absolutely necessary.
It is necessary to wind an electromagnetic coil around the element body to make the element
work. In order to directly contact an object to be vibrated with the main body, the wound coil
interferes, so at present the portion of the tip of the element slightly out of the coil is used as the
mover. Because such a structure must be taken by all means, the way of use is naturally limited.
Therefore, it is an object of the present invention to construct a more convenient vibration
generation system.
[0005]
The following vibration generating system shown in FIG. 1 and FIG. 2 having a function similar to
that of a giant magnetostrictive element is constructed. The oscillator (1) is placed directly on the
main body (2) of the same material and in which all the parts have the same properties, or via a
fixing member etc., and its movable part (3) is also the main body (2) The vibration is generated
using the method of connecting the object to be vibrated to the main body (2), which is
connected directly or with a fixing tool etc. to a place different from the place where the above
oscillator (1) is connected and installed system. The oscillator in the present invention is a
conventional electromagnetic actuator or super magnetostrictive element actuator.
[0006]
Reproduction System of Super Magnetostrictive Element The vibration generating system of the
present invention starts from reproducing the phenomenon of the super magnetostrictive
element whose dimensions change when magnetism is applied using a conventional vibration
generating device. Therefore, focusing on the characteristics of the giant magnetostrictive
element again, it is that the element itself becomes larger when magnetism is applied. It would

probably not be possible to reproduce the exact same thing with a conventional vibration
generator, but similar things are not necessarily impossible if we look a little more closely. Next,
let's look at how to use the giant magnetostrictive element. As shown in FIG. 3 (A), generally, the
giant magnetostrictive element (4) is generally elongated, and a coil (5) is placed around it to
provide magnetism, thereby providing an input signal In response, the movable part (6) is
configured to vibrate up and down. However, an actual giant magnetostrictive element expands
and contracts in both directions as in (B) and also in all directions in an oblique direction, and in
this way it expands and contracts in the longitudinal direction as in (C). You will only be using
This is probably the most rational way, but it also ignores the energy that is stretching in the
lateral or other direction. As described above, the actual usage of the giant magnetostrictive
element utilizes only stretching and contracting in the longitudinal direction. If it is this, it will
become possible to reproduce this with the conventional vibration generator by comprising as
follows. To do this, as in (D), place the oscillator (8) on the main body (7) that is entirely the same
material and has the same properties in all parts, and move the movable part (9) to the same
main body (7) ) The fixed position of the upper oscillator (8) is different from the one where it is
installed. In this way, the movable part (9), which expands and contracts with the input signal,
directly expands and contracts the body itself between these two places installed in the body (7).
Thus, as if the giant magnetostrictive element expands and contracts, vibrations occur as the
main body (7) expands and contracts. To use, bring the object to be vibrated into contact with the
body anywhere.
[0007]
There is no particular need to fix the body to the object to be vibrated with a screw or a
connector, and any object can be vibrated simply by contacting the body, so the application
range is wide. According to the current usage of the giant magnetostrictive element, it is possible
to bring an object giving vibration into contact only at a portion where the element is slightly out
of the tip of the coil, because the presence of the coil disturbs it, In the vibration generating
system of the present invention which generates the same kind of vibration, it is possible to
contact any part of the main body. There is no need to directly move the object to be vibrated,
only moving parts (3) that actually move, and since these may be made of light materials, almost
no centrifugal force is applied for vibration, and wasteful consumption of kinetic energy is Few.
When the input signal to the oscillator (1) disappears, the originally light movable part (3)
immediately stops, so the input responsiveness is extremely high. The input signal to the
oscillator (1) can correspond to any changing waveform. Since the oscillator (1) and the movable
part (3) are respectively installed in the main body (2), the generated vibrational energy is not
transmitted to the other third object in vain. Because of its simple structure, its application range
is wide, from small ones to large ones.

The following compares with the prior art. Patent Document 1: JP-A 2007-19623, (0016) (by
passing a driving current from an external current supply circuit to the voice coil, the vibration
transmitting material is interposed against the plate surface of the diaphragm 1 Vibration in
parallel. Since the movable part is connected to the vibrating plate through the connector, there
is no function to give vibration to the object to which other vibration is desired. In this respect,
the present invention can give vibration to any object by bringing it into contact with the main
body. Patent Document 2 (Japanese Patent Application Laid-Open Publication No. 2005-148006)
movably moves the test piece giving vibration so that (the test piece is placed and the movable
portion is capable of rectilinearly reciprocating) It is necessary to put on a club. In this case, the
shape and size of the test piece are limited, and unlike the case where the main body is installed
in contact with the one giving vibration as in the present invention, the application range is
narrow. In JP-A-2009-175122, although the rod of the vibrator is configured to give vibration to
the transmitter, the vibrator itself is also vibrated by reaction and the vibration is not transmitted
effectively. . In that respect, in the present invention, the oscillator and its movable part are
connected to the main body, and the vibration energy is effectively used without being
transmitted to the third object in vain. In Japanese Patent Application Laid-Open No. 2001258095, since the upper lid is extremely thin and elastic as compared with the thickness of the
case, the expansion and contraction of the giant magnetostrictive element generates vibrations,
but the case is also reactive Vibration occurs and energy loss is large. In that respect, in the
present invention, the oscillator and its movable part are connected to the main body, and the
vibration energy is effectively used without being transmitted to the third object in vain. In this
prior art, although the cap of the upper lid portion is brought into direct contact with the object
of vibration transmission for use, the vibration generating system of the present invention is not
limited to the upper lid portion but any of the main body. The application range is wider than in
this prior art, as it is sufficient to contact the vibration transmission target somewhere. Patent
Document 5 JP 2009-290727 A uses the vibrator cover which is a movable portion adhered to
an article. However, in this case, instead of being transmitted to the article, the vibration is
transmitted to the case body of the bag which is also the non-moving part by reaction, and the
energy loss is large. In that respect, in the present invention, the oscillator and its movable part
are connected to the main body, and the vibration energy is effectively used without being
transmitted to the third object in vain.
