Ling Yin features a design with a sense of technology. Its shell has hollowed - out parts, which not only make it easy to view the internal structure but also optimize sound transmission. "Ling Yin" combines the principle of tuning - fork resonance with the rotation of a fidget spinner. When playing, the collision with the tuning fork emits a clear sound, retaining the original playing method and adding auditory interest.
There are various playing methods with different experiences. When steel balls are put in and rotated, when it is vertical, you can hear the clear and intensive sound of the steel balls hitting the tuning - fork. When it is rotated horizontally, the sound of the steel balls disappears, leaving only the lingering sound of the tuning fork.
It supports DIY. You can replace the 8mm steel balls with glow in the dark beads. When rotating, it forms a halo, which is more visible in the dark, bringing an audio - visual enjoyment.
