PROBLEM TO BE SOLVED: To expand a frequency range which a biological sound stethoscopic apparatus can cover.SOLUTION: A biological sound stethoscopic apparatus (100) comprises an acquisition unit (11) for acquiring a biological sound of a person who receives stethoscopy and a diaphragm (21) for holding the acquisition unit. The acquisition unit contains a vibration sensor for outputting an electric signal according to the biological sound. By using the vibration sensor, a frequency range that a biological sound stethoscopic apparatus can cover is expanded compared with a case in which a microphone is used or a non-electronic stethoscope is used.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】生体音聴診装置の聴診可能な音域を拡張する。【解決手段】生体音聴診装置(100)は、被聴診者の生体音を取得する取得部(11)と、該取得部を保持するダイヤフラム(21)と、を備える。取得部は、生体音に応じた電気信号を出力する振動センサを含む。振動センサを用いることにより、マイクロフォンを用いた場合や、電子化されていない聴診器に比べて、聴診可能な音域を拡張することができる。【選択図】図2
