Description

  The present invention relates to an apparatus capable of floating and holding a main body in the air.

Orin is one of the Buddhist instruments that uses a ringer to squeeze in front of Buddha, such as a Buddhist altar or a funeral place.
Conventionally, the main body of the bowl shape is placed on the cushion, and the main body is made to ring for a long time, but the attenuation of the sound is still large.
Further, although it has been proposed that the phosphorus main body is held and oscillated using a spring or the like, the supporting portion of the phosphorus main body is also one of the factors of sound attenuation.

The applicant of the present invention has so far proposed a technology for suspending the main body of the ball using magnetic force or air pressure (Patent Document 1).
However, at this time, it is difficult to stably hold the floating main body in the air, and a holding means such as a balancer is required, so the main body is completely floating in the air when viewed from the outside. The image I was doing was inadequate.

  An object of the present invention is to provide a floating bearing device in which a main body of a bearing floats stably in the air by a repulsive force of magnetic force.

The levitation rolling device according to the present invention comprises a barrel main body, and a levitating means for levitating the barrel main body by a magnetic force, and the levitating means comprises a levitating levitation levitating by a magnetic force and the levitating float by a magnetic force It has a floatation device which floats up, and the above-mentioned float main body is mounted or connected to the above-mentioned floater.
Here, it is preferable that the floating device has positioning means for positioning the height or / and horizontal direction of the floating element by magnetic force.

In the present invention, the floater floats by the repulsive force of the magnetic force generated from the floatation device.
For example, when a magnet comprising a doughnut-shaped circular ring generating a magnetic force is provided on the levitation device side, and the floater is formed in a disk shape (coin shape) whose outer diameter is smaller than the inner diameter of the doughnut-shaped circular ring. When the facing surfaces of the floating device and the float are the same polarity, and the center of the disk-like float and the center of the donut-shaped circular ring coincide on the same central line, The repulsive force makes it float in the air, but when the center is shifted, the attraction force of the different pole becomes stronger than the repulsive force of the same pole, and the float drops and becomes unstable. .
Therefore, control was performed so that the center of the floater and the center of the circular ring coincide with the same center line.
Thus, the height of the main body of the cage can be controlled by adjusting the repulsive magnetic force, and the position in the horizontal direction can be adjusted by the auxiliary magnetic force of the coil or the like.

Here, the magnetic force generation means on the floating device side may be either a permanent magnet or an electric magnet, or may be a combination of them.
The positioning means of the float may be control means of an electromagnetic force which detects the center of the float or controls the center of the float to coincide with the center of the float side.

Due to the repulsive force of the magnetic force, the levitated float (rotary main body) generates a rotational force due to the magnetic flux of the magnetic force passing through the float.
Therefore, the present invention may include rotation control means for controlling the rotation or stop state of the ball body lifted by the float.
In this case, the rotation speed may be increased or decreased, or may be stopped.
By rotating the main body of the cage, a solemn atmosphere can be obtained, and the position of the main body of the main body, which is hit with a rod, changes.
In addition, the slow rotation of the main body causes an unconventional change in the aftermath of hitting.
In addition, by controlling the rotation, it is possible to easily obtain a preferable beat by utilizing the Doppler effect generated at the time of rotation.
For example, if it is rotating clockwise as viewed from the top, from the right side the sound source approaches in the direction of the viewer from the right side, so a sound of vibration higher than the reference frequency of the phosphorus body can be heard. You can hear a low vibration sound from
This becomes a combined sound, and the difference in the pitch is heard as a roar. That is, if it rotates quickly, short pitches will occur, and if it rotates slowly, it will produce longer pitches. By controlling this, you can get your favorite beat.
Of course, if the number of revolutions is constant while the sound is sounding, a constant beat will be obtained.
By changing the number of revolutions while the sound is sounding, it is possible to have complex variations of beating.
In the present invention, a position shift prevention means may be provided which prevents the ball body floated by the float from falling due to position shift in the horizontal direction.
If the floating main body is accidentally hit too hard, the floating center of the main body may be largely deviated and may fall.
Therefore, for example, a pin may be erected around the periphery or a saucer may be provided to cover the periphery so that the center position of the float does not deviate beyond a predetermined range, and the center of the floater or the main body penetrates A hole may be provided, and a guide pin inserted into the through hole may be erected.

The main body of the ball is preferably made of a nonmagnetic material such as a copper alloy such as brass or an aluminum alloy.
The following example can be considered for the relationship between the main body and the floater.
Place the body on the floater.
In this case, a magnetic material may be provided on the bottom of the cage main body and magnetically attached onto the float. Alternatively, the magnetic attachment part of the cage main body may be made to be convex so as to oscillate.
The float is fixed to the outer bottom surface or the inner bottom surface of the bowl body.
Bury the floater inside the body of the cage.
Connect the body to the floater.
This connection method may be fixed connection, elastic connection, or swing connection.

In the levitation rolling device according to the present invention, since the main body of the cage can be floated in the air by the repulsive force of the magnetic force without supporting the conventional guide, the body is floating in the air from the outside. It looks like, and when it squeezes with a thin rod, there are less factors promoting the damping of the vibration, and a longer aftertone remains than before.
The rotation of the main body provides a gyro effect, which is effective in reducing the influence of hitting.
