Musical Instrument Toys

Abstract

It is a musical instrument toy that produces a musical scale when the buttons arranged in a spiral are pressed with the fingers. Reference figures 1 and 2 show the relationship between the design of the plan view and the sound. Reference figure 1 shows that the relationship between "the sound of any one button on the dotted spiral" and "the sound of the button next to this button on the right from the center, connected to this button by a dotted line" is that the sound of the button on the right is always a semitone higher. Reference figure 2 shows that the buttons inside the dotted ellipses produce the same musical scale, and within each ellipse, the sound gets higher by one octave from the inside to the outside.
