MUSICAL INSTRUMENT BASED ON WATER-HAMMER, HYDRAULOPHONIC, OR HYDRAULIDIOPHONIC PERCUSSION

摘要

A musical instrument or other multimedia input device is disclosed. User inputisby way of hitting or striking water abruptly in order to produce an at leastpartiallytransient acoustic disturbance, vibrations, or change in the water. In oneembodimenta dozen or so rigid pipes of various lengths (and possibly various diameters)emitfluid which is for being struck by a user at an open end of each pipe. Theotherend of each pipe is connected to an elastic tubing or other elastic medium,such asa diaphragm or bulb, resulting in a hydraulic resonator. In another embodimentthe resonators are formed from variously sized Bordeaux wine bottles orFlorenceflasks encased completely in cement, except for the mouths of the bottles,each bottlehaving two additional holes drilled for a water inlet port and a listeningport. Eachhydraulic resonator is fitted with a sensor that senses the vibrations in thewaterand amplifies the vibrations into a sound reproduction system, such as anentirelyacoustic impedance matcher or an electrical amplification system.
