USE OF PULSED THERMAL RADIATION AND NANO-PARTICLES FOR THE EFFECTIVE GENERATION OF SOUND WAVES IN KHZ RANGE

摘要

The present invention relates to a high efficient sound wave generator of a kilo hertz range using a pulse heat radiation beam and nanoparticles. The technical point of the present invention is to maximize the productivity and the efficiency of a sound wave generation by easily obtaining energy with a large amplitude and to minimize a loss of a pulse beam. Wherein, a suspension type vibration (pulse) generating unit is formed on the end of a light cutter and a vibration (matter wave and pressure wave) in an inner aqueous solution is generated when the nanoparticles float on the aqueous solution and are thermally expanded or contracted by the transmitted pulse beam.
