Ethereal Sound
★Exhibit Content: Metal tube vibration sound production and pitch variation patterns ★Interaction: Mechanical interaction ★Operation: Pull the suspended striking stick to strike metal sound tubes of different lengths in sequence, and listen to the crisp sounds of varying pitches. ★Exhibit Description: The exhibit consists of an arched decorative backboard, multiple sets of metal sound tubes of graduated lengths, a suspended striking component, and a floor-standing base. It is a recommended exhibit from the PopsciCat Exhibit Store. The backboard is decorated with musical notes and childlike floral patterns. The sound tubes are arranged in order of length and equipped with a pull-cord striking device. After pulling the striking stick and releasing it, the striking head hits the metal tube body. Tubes of different lengths produce clear musical tones of different pitches. Continuous and orderly striking can play simple melodies, allowing visitors to intuitively feel pitch differences through hands-on interaction and understand the basic physical logic of sound production in wind instruments. ★Scientific Principle: Sound is produced by object vibration. When a metal tube is struck, it vibrates, simultaneously causing the air column inside the tube to vibrate and resonate, amplifying the sound to form a pleasant musical tone. Due to different tube lengths, the natural frequencies of vibration differ significantly: the longer the tube, the lower the vibration frequency, and the deeper the pitch; the shorter the tube, the higher the vibration frequency, and the crisper the pitch. Through intuitive striking experience, the exhibit helps visitors understand the correspondence between pitch and vibration frequency, and recognize the core sound production principle of wind instruments.
