WIPO Patent Application WO/2010/143380
Kind Code:
A1
Abstract:
A sound wave generator which has better output characteristics than those in the past is provided based on a base layer and insulating layer combination which could not be predicted in the past. The sound wave generator is provided with a base layer, an insulating layer disposed on the base layer, and a heat pulse source which applies a heat pulse to the insulating layer, wherein the base layer comprises graphite or sapphire, and the insulating layer comprises crystalline fine particles which include silicon or germanium. The heat pulse source is, for example, a heat pulse generating layer which is disposed on the surface of the insulating layer opposite to the base layer side and applies a heat pulse to the insulating layer.
