Title:
音波発生器とその製造方法ならびに音波発生器を用いた音波発生方法
Document Type and Number:
Japanese Patent JP4688977
Kind Code:
B2
Abstract:
A sound wave generator that exhibits more excellent output properties than conventional ones, based on the combination of a base layer and a heat-insulating layer that cannot be expected from conventional techniques is provided. The sound wave generator includes a base layer; a heat-insulating layer disposed on the base layer; and a heat pulse source that applies heat pulses to the heat-insulating layer. The base layer is composed of graphite or sapphire, and the heat-insulating layer is composed of crystalline fine particles containing silicon or germanium. The heat pulse source, for example, is a heat pulse-generating layer that is disposed on the surface of the heat-insulating layer opposite to the base layer and applies heat pulses to the heat-insulating layer.
