The volume is never loud.
However, if the volume is not this level, you will find it “troublesome”.
It is an image that echoes behind the “quiet space”.
Not only can you hear the sound, but you can calm down even if you are looking at it.
Three important points
・Not only the sound but also the movement changes, so you can feel at ease even if you look at it.
・It can be stored compactly and can be used in various places.
・What you can do by keeping it spinning for a long time.
・Price: $ 30
・Diameter: about 7 cm
・Height: about 12 cm
・ Accessories: Hex wrench for tightening (2 pcs), USB connection cable
It is sold as a set with an instrument
Since it is a USB connection, it can be powered from a mobile battery or an outlet.
Mobile battery is not included.
Parts and settings (Japanese audio)
This is also “mute”
The muted sound is unexpectedly comfortable as if you were listening in the water. Please try.
・ Sometimes the motor makes a strange noise
・ The ball gets caught by the magnet
You may hear a snarling sound of the gears.
This may be due to individual differences in the motor.
Grease is applied to the gear part, but it does not fit completely.
It does not always make a strange noise, but it may occur.
In many cases, the abnormal noise can be subsided by stopping it once and then starting it again after a while.
I think that the only way to eliminate abnormal noise is to change the motor itself.
In that case, it seems that the current compactness cannot be realized.
Twirl is “weak”
The twirl wire is a 0.3 mm piano wire. Of course, it sticks to the magnet.
By hitting the magnet on the striking surface, not only does it rotate on the surface of the twirl, but it also causes bouncing movements.
You may get stuck in the magnet.
If you play the ball lightly, it will start moving immediately.
Also, please be aware that although it can be solved by changing the rotation speed or the position of the magnet, there is a possibility of “getting caught”.
* There is a solution by processing, but I am worried that the “easiness of magnets” will be lost.
