A breath training device includes a doll, a light emitting module, and a processing module. The light emitting module for emitting light is disposed on the doll. The processing module is electrically connected to the light emitting module. When the light emitting module is enabled, the processing module controls the light emitting module to regularly change the luminance of the light. Thus, a user may regularly breathe according to the change of the luminance.一種呼吸訓練裝置,包括一玩偶、一發光模組、以及一處理模組。發光模組設置於上述玩偶,並用以產生一光線。處理模組電性連接於上述發光模組。當上述發光模組致能時,上述處理模組控制上述發光模組規律地改變上述光線的亮度,因此使用者可依據上述亮度的變化來進行規律的呼吸。1‧‧‧呼吸訓練裝置10‧‧‧玩偶11‧‧‧包覆套12‧‧‧軟性填充本體13‧‧‧身體部14‧‧‧頭部15‧‧‧嘴部16‧‧‧手部17‧‧‧腳部20‧‧‧處理模組30‧‧‧發光模組31‧‧‧發光元件40‧‧‧電源供應元件50‧‧‧開關元件60‧‧‧感測模組61‧‧‧感測器62‧‧‧感測器70‧‧‧揚聲器Z1‧‧‧腹部區域
