A kind of stethoscope structure improvement,The stethoscope system include just listen cylinder base,One be pivoted what this listen the sound guide tube at cylinder base and being showed a link like state,And two groups of listening tubes for setting at the what sound guide tube and being showed a link like state； Wherein this listens cylinder base system to have a sound collection chamber,The sound collection chamber system for an absorptive membrane merging be laid with,A connecting seat,It is to be in adjacent states at the position what sound collection chamber one end,And a heating device,System is equipped with a recessed group seat-joined,It is in the locking part of stationary state in chamber of the group seat-joined system equipped with a merging what attachment base,And system is placed in for a solar panels at the what group seat-joined,And system is placed in for a heating plate at the accommodating space of the locking part,Thereby,By the group seat-joined locking what of the heating device, this is listened at the attachment base of cylinder base,It absorbs sunlight using the solar panels of the heating device and is converted to electric energy,And then the heating plate of the heating device is heated,Cause the effect for listening cylinder base that tepid state is presented.一種聽診器結構改良，該聽診器係包含有一聽筒座、一樞設於該聽筒座處而呈連結狀態之導音管，及二組設於該導音管處而呈連結狀態之聽管；其中該聽筒座係具有一集音室，該集音室係供一吸音膜置入鋪設、一連接座，係位於該集音室一端處而呈相鄰狀態，及一加熱裝置，係設有一呈凹陷狀之組接座，該組接座係設有一置入於該連接座之腔室內而呈固定狀態之鎖合部，並於該組接座處係供一太陽能板置入，且該鎖合部之容置空間處係供一加熱板置入，藉此，將該加熱裝置之組接座鎖固於該聽筒座之連接座處，其利用該加熱裝置之太陽能板吸收太陽光而轉換為電能，進而對該加熱裝置之加熱板進行加熱，致使該聽筒座呈現溫熱狀態之效果。
