To achieve the size reduction of a thermoacoustic device having a plurality of pieces of at least either of loop piping in which a prime mover is arranged, and loop piping in which a receiver is arranged.SOLUTION: A thermoacoustic device comprises: input loop piping 11, 51; thermoacoustic engine parts 10, 50 having input parts 12, 52 for converting thermal energy to acoustic energy; output loop piping 21, 31 and 61; thermoacoustic refrigeration parts 20, 30 and 60 for generating cold heat by converting the acoustic energy to the thermal energy, and having output parts 22, 32 and 62; and connecting piping 40 to 46 for connecting the input loop piping 11, 51 and the output loop piping 21, 31 and 61. The acoustic energy generated by the thermoacoustic engine parts 10, 50 is transmitted to the thermoacoustic refrigeration parts 20, 30 and 60 via the connecting piping 40 to 46. At least either of the thermoacoustic engine parts 10, 50 and the thermoacoustic refrigeration parts 20, 30 and 60 are arranged in a plurality of pieces.SELECTED DRAWING: Figure 2 【課題】原動機が設けられたループ配管または受動機が設けられたループ配管の少なくともいずれかを複数備える熱音響装置において、小型化を図る。【解決手段】入力ループ配管１１、５１と、熱エネルギーを音響エネルギーに変換する入力部１２、５２とを有する熱音響エンジン部１０、５０と、出力ループ配管２１、３１、６１と、音響エネルギーを熱エネルギーに変換して冷熱を生成する出力部２２、３２、６２とを有する熱音響冷凍部２０、３０、６０と、入力ループ配管１１、５１および出力ループ配管２１、３１、６１を接続する連結配管４０〜４６とを備えている。熱音響エンジン部１０、５０で生成した音響エネルギーは、連結配管４０〜４６を介して熱音響冷凍部２０、３０、６０に伝達される。熱音響エンジン部１０、５０および熱音響冷凍部２０、３０、６０の少なくともいずれかが複数設けられている。【選択図】図２
