Laser Harp

Mobile Science Museum · Acoustics

Operation: Pluck the strings and enjoy the beautiful music. Function Overview: The exhibit consists of a harp model, laser beams, and photoelectric sensors. By "plucking" the strings with your hand, you can play music. Scientific Principle: The harp strings are laser strings formed by 8 sets of lasers above and 8 corresponding sets of photosensitive sensors below. Each laser emits a beam that hits the corresponding receiver below. When you pluck the "string," your finger blocks the laser beam, triggering the corresponding photoelectric sensor, which causes the sound system to produce the corresponding musical note. By continuously plucking the "strings," you can hear beautiful harp music, and visitors can also create their own music.
