Gaussian Melody
Exhibit dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Exhibit composition: Consists of an ABS plastic molded box, ABS plastic molded base, ABS milky white plastic molded operating surface, and a color silk-screened flip-up instruction board, display core mechanism, etc. The exhibit is equipped with a concave sound-gathering disc, a triangular groove filled with steel nails, and a steel ball. Slowly rotate the turntable to let the ball roll down continuously, and listen to the melody of the ball hitting the steel needles. The steel needles inside the triangular frame are arranged according to a Gaussian distribution. When we rotate the turntable, the ball continuously falls and hits the steel needles, producing sound. Because the steel needles have different lengths, the sounds produced are different, so the sound we hear presents a unique melody.
