A kind of duct-type loudspeaker arrangement measured with physiological information, including at least having a headset body, a detection light emitting part, one first detection light receiver member, one second detection light receiver member and a processing unit. Wherein, the detection light emitting part, the first detection light receiver member, the second detection light receiver member interval setting what headset body dress the position in one ear canal of what of Hou position, the detection light emitting part projects a detection light to the ear canal, and the first detection light receiver member and the second detection light receiver member then receive the detection light reflected from the ear canal respectively and the detection light are converted to one first measurement signal and one second measurement signal. The processing unit receives the first measurement signal and the second measurement signal from the first detection light receiver member and the second detection light receiver member and is converted to a physiological signal.一種具有生理訊息量測的耳道式揚聲裝置，至少包含有一耳機本體、一檢測光發射件、一第一檢測光接受件、一第二檢測光接受件以及一處理單元。其中，該檢測光發射件、該第一檢測光接受件、該第二檢測光接受件間隔設置於該耳機本體穿戴後位於一耳道內的部位，該檢測光發射件對該耳道投射一檢測光，該第一檢測光接受件及該第二檢測光接受件則分別接受自該耳道反射而來的該檢測光並將該檢測光轉換為一第一量測訊號及一第二量測訊號。該處理單元自該第一檢測光接受件及該第二檢測光接受件接受該第一量測訊號及該第二量測訊號並轉換為一生理訊號。
