Laser Harp
Operation: Pluck the strings and enjoy the beautiful music. Function Overview: The exhibit consists of a harp model, laser beams, and photoelectric sensors. Pluck the strings with your hand to 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 aligns with the receiver below. When you pluck a 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.
