摘要
Disclosed herein is a high-efficiency kilohertz-range acoustic wave generator using a pulsed thermal radiation beam and a nanostructure. A nanorod unit having a high thermal expansion coefficient is provided behind a light interrupter so that the efficiency of generating acoustic waves can be enhanced. A pulse beam generated from the light interrupter is directly radiated onto the nanorod unit having a nanorod bundle structure with a nanorod-opposite-end support. Thermal deformation of the nanorod unit attributable to thermal expansion and contraction is repeated. In this way, the amplitude of sound waves can be increased, and relatively high decibel sound can thus be generated.
