To cause a gas-liquid phase change of condensable fluid to be generated continuously in a thermoacoustic device using condensable fluid.SOLUTION: A thermoacoustic device includes; acoustic transmission pipes 101, 201, and 300 in which working fluid is encapsulated; an energy conversion part 102a provided in the acoustic transmission pipe 101 for converting thermal energy to acoustic energy by forming a predetermined difference in temperature between one end part and the other end part; an energy consumption part 202a provided in the acoustic transmission pipe 201 for converting the acoustic energy to a different kind of energy; and a partition wall part 103 provided between the energy conversion part 102a in the acoustic transmission pipe 101 and the energy consumption part 202a. The working liquid contains condensable fluid that can make a gas-liquid phase change, and the partition wall part 103 inhibits the passage of the condensable fluid and is deformed on the basis of the acoustic energy.SELECTED DRAWING: Figure 1 【課題】凝縮性流体を用いる熱音響装置において、凝縮性流体の気液相変化を継続的に生じさせる。【解決手段】作動流体が封入された音響伝達管１０１、２０１、３００と、音響伝達管１０１内に設けられ、一方の端部と他方の端部との間に所定の温度差を形成することで熱エネルギを音響エネルギに変換するエネルギ変換部１０２ａと、音響伝達管２０１内に設けられ、音響エネルギを異なる種類のエネルギに変換するエネルギ消費部２０２ａと、音響伝達管１０１内におけるエネルギ変換部１０２ａとエネルギ消費部２０２ａとの間に設けられた隔壁部１０３とを備える。作動流体は、気液相変化可能な凝縮性流体を含んでおり、隔壁部１０３は、凝縮性流体の通過を阻害するとともに、音響エネルギに基づいて変位する。【選択図】図１
