Magnetic driving portion 50 is passed through using the relationship between the frequency of this alternating magnetic field and the vibration easness of vibrating body 20
With the alternating magnetic field of the first eigentone identical frequency and so that vibrating body 20 is vibrated along left and right directions, by with it is second solid
There is the alternating magnetic field of vibration frequency identical frequency and vibrating body 20 is made to be vibrated along upper and lower directions.Hereinafter, will be by consolidating with first
The case where having the alternating magnetic field of vibration frequency identical frequency and vibrating body 20 is made to be vibrated along left and right directions, is referred to as solid with first
There is vibration frequency to drive vibrating body 20 in left-right direction, it will be by making with the alternating magnetic field of the second eigentone identical frequency
The case where vibrating body 20 is vibrated along upper and lower directions referred to as drives vibrating body 20 along the vertical direction with the second eigentone.
Then, the method for making the vibration action of vibrating body 20 stablize is illustrated.As described above, such as elastic supporting part 40
The leaf spring of such bending construction has is easy to happen flexible deformation on the direction orthogonal with folding line, and in side along the crease
It is difficult to happen upwards and deforms this feature.Therefore, in the present embodiment, using the feature of the leaf spring of this bending construction, come
Inhibit elastic supporting part 40 along deformation in the front-back direction.Moreover, thus vibrating body 20 is inhibited to be moved along in the front-back direction,
Make stablizing along the vibration action of left and right directions and upper and lower directions for vibrating body 20.
Moreover, in the leaf spring of this bending construction, the width dimensions of flat part 42 are more more than the length ruler of flat part 42
It is very little, then it is more difficult to deform on direction along the crease.In the present embodiment, the leaf spring of this bending construction is utilized
Feature is formed as elastic supporting part 40, and the width dimensions of flat part 42 are bigger than the length dimension of flat part 42, are easy as a result,
Inhibit elastic supporting part 40 along deformation in the front-back direction.
In addition, in the leaf spring of this bending construction, the peripheral part of flat part 42 is to elastic supporting part 40 to along the crease
The difficulty of deformation in direction be affected, and the part (part for leaning on central portion) for avoiding peripheral part of flat part 42
It influences smaller than the influence of the peripheral part of flat part 42.On the other hand, by being formed in the part for the peripheral part for avoiding flat part 42
Opening portion 42a makes under the mechanical strength relative to the direction (left and right directions and upper and lower directions) orthogonal with folding line of flat part 42
Drop, can make elastic supporting part 40 be easy that flexible deformation occurs on the direction orthogonal with folding line.
In the present embodiment, using the feature of the leaf spring of this bending construction, the peripheral part of avoiding in flat part 42
Opening portion 42a is formed at position, thus, it is suppressed that the case where elastic supporting part 40 deforms readily along front-rear direction makes
Readily along left and right directions and upper and lower directions flexible deformation occurs for elastic supporting part 40.Moreover, the ruler by adjusting opening portion 42a
It is very little, so as to adjust elastic supporting part 40 along left and right directions and the difficulty of the flexible deformation of upper and lower directions.
Then, the effect of present embodiment is illustrated.In the vibration generating apparatus 1 of present embodiment, elasticity branch
The elastic supporting part 40 of bearing portion 40 is the leaf spring for being formed with multiple bending parts 41 and generally rectangular two flat parts 42, this is more
A bending part 41 is with folding line along the front-rear direction (third orthogonal with left and right directions (first direction) and upper and lower directions (second direction)
Direction) mode bend, which prolongs from a bending part in multiple bending parts 41 towards another bending part
It stretches.The leaf spring of this bending construction have be easy to happen flexible deformation on the direction orthogonal with folding line and along the crease
It is difficult to happen on direction and deforms this feature.Therefore, it is possible to make elastic supporting part 40 readily along left and right directions and upper and lower directions
Occur flexible deformation, and inhibit elastic supporting part 40 along deformation in the front-back direction.As a result, even by electromagnet 60
Magnetic force between (the first magnetic field generation mechanisms) and permanent magnet 70 (the second magnetic field generation mechanisms) and apply edge to vibrating body 20
Power in the front-back direction, can also inhibit being moved along in the front-back direction for vibrating body 20, can make vibrating body 20 along a left side
The vibration action of right direction and upper and lower directions is stablized.
In addition, in the vibration generating apparatus 1 of present embodiment, pass through avoiding at the position of peripheral part in flat part 42
Opening portion 42a is formed, so as to inhibit elastic supporting part 40 to deform readily along front-rear direction, and makes elastic bearing
Readily along left and right directions and upper and lower directions flexible deformation occurs for portion 40.Moreover, the size by adjusting opening portion 42a, it can
Adjust elastic supporting part 40 along left and right directions and the difficulty of the flexible deformation of upper and lower directions.As a result, can make to shake
The vibration action of kinetoplast 20 is stablized, and vibrating body 20 is made to be vibrated readily along left and right directions and upper and lower directions, and can adjust
The difficulty of the vibration of vibrating body 20.
In addition, in the vibration generating apparatus 1 of present embodiment, by the way that elastic supporting part 40 is formed as, flat part 42
Width dimensions (size in direction along the crease) than flat part 42 length dimension (along the size of extending direction) greatly, from
And can further suppress elastic supporting part 40 along deformation in the front-back direction, the vibration action of vibrating body 20 can be made more
Stablize.
In addition, in the vibration generating apparatus 1 of present embodiment, Magnetic driving portion 50 by with first coefficient of elasticity and shake
Corresponding first eigentone of quality of kinetoplast 20 drives vibrating body 20, so as to make vibrating body 20 readily along left and right
Direction vibrates, and is difficult to vibrate along upper and lower directions.In addition, Magnetic driving portion 50 by with first coefficient of elasticity and vibrating body 20
Corresponding second eigentone of quality drive vibrating body 20, so as to make vibrating body 20 shake readily along upper and lower directions
It is dynamic, and be difficult to vibrate along left and right directions.As a result, the vibration action of vibrating body 20 can be made to stablize, and realize vibrating body
20 along left and right directions and the desirable vibration action of upper and lower directions.
In addition, in the vibration generating apparatus 1 of present embodiment, it, can by alternating magnetic field caused by electromagnet 60
Make the first magnetized area 73a of the magnetic core 61 of 60 side of electromagnet and the magnetic pole of the side as 70 side of permanent magnet attract each other or
It is mutually exclusive, it is mutually exclusive or attract each other with the second magnetized area 73b of the magnetic pole of another party as 70 side of permanent magnet.
Moreover, by using the magnetic force between this electromagnet 60 and permanent magnet 70, vibrating body 20 can be made readily along right and left
It is vibrated to upper and lower directions.Moreover, even if magnetic force is acted between permanent magnet 70 and electromagnet 60, elasticity is also inhibited
