Beschreibung
Zusammenfassung:	A thermoacoustic device includes a loop tube (11) in which a working gas is sealed; a stack in which a temperature gradient is generated in a tube axis direction of the loop tube (11), the stack beingprovided in the loop tube (11); and a diaphragm structure (40) including a diaphragm (39) provided in the loop tube (11) and an operating unit, the diaphragm (39) having a surface (39a) extending ina direction intersecting the tube axis direction and being configured to vibrate with a component of vibration in the tube axis direction, and the operation unit (41) being configured to apply a physical quantity that is required, to the diaphragm (39) to change a rigidity of the diaphragm (39) in the tube axis direction. 热声装置包括：环管(11)，在环管中密封工作气体；堆叠，在堆叠中在环管(11)的管轴线方向上产生温度梯度，堆叠设置在环管(11)中；和隔膜结构(40)，包括操作单元和设置在环管(11)中的隔膜(39)，隔膜(39)具有在与管轴线方向相交的方向上延伸的表面(39a)且被构造成振动且具有在管轴线方向上的振动分量，并且操作单元(41)被构造成对隔膜(39)施加所需的物理量，以改变隔膜(39)在管轴线方向上的刚度。
