This invention relates to a posture adjustment device capable of indirectly adjusting body posture of a user by an adjusting object, comprising a gas single unit, a gas control module, and a control module. The gas single unit is formed into a receiving space and an opening. The gas control module determines whether to output an internal gas to the receiving space or to release an external gas from the receiving space according to a driving signal and receives an external control instruction to generate the driving signal. The control module executes an application program to generate the control instruction, wherein the application program selectively determines generating the control instruction according to the audio signal of the audio unit of the control module.本發明係一種姿態調節裝置,能夠藉由調節物件以間接地調整使用者的身體姿態,該姿態調節裝置包含氣體單體、氣體操控模組與控制模組。該氣體單體形成容置空間與開口。該氣體操控模組根據驅動訊號以決定將內部氣體輸出至該容置空間或自該容置空間洩漏外部氣體,以及該氣體操控模組接收外部的控制指令以產生該驅動訊號。該控制模組執行應用程序以產生該控制指令,其中該應用程序選擇性根據該控制模組之音訊單元的音源信號決定產生該控制指令。2‧‧‧物件10‧‧‧姿態調節裝置12‧‧‧氣體單體122‧‧‧第一表面層124‧‧‧第二表面層126‧‧‧容置空間128‧‧‧開口14‧‧‧氣體操控模組142‧‧‧驅動模組144‧‧‧連接管146‧‧‧第一通訊單元16‧‧‧控制模組162‧‧‧處理單元164‧‧‧第二通訊單元166‧‧‧音訊單元IAIR‧‧‧內部氣體EAIR‧‧‧外部氣體DS‧‧‧驅動訊號AP‧‧‧應用程序CI‧‧‧控制指令SS‧‧‧音源信號
