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 hand or finger. Reference Figure 1 and Reference Figure 2 show the relationship between the design of the plan view and the sound. In Reference Figure 1, the button closest to the center of the spiral among the buttons connected by dotted lines is designated as "Do", and the scale ascends from this button to the adjacent button to the right, connected by dotted lines, in order from Re Mi Fa So La Si Do, with the scale rising one octave as the spiral goes around once. Reference Figure 2 shows that the buttons inside the dotted ovals have the same scale, and within each oval, the scale increases by one octave from the inside to the outside.
