To provide a physiological signal sensor device capable of achieving the object of occasional use, real time detection, prevention of an accident before occasion, which is easy to operate, easy to maintain and familiar easily.SOLUTION: In a physiological signal sensor device including a sound conducting member 110, a sound collecting member and a sound source receiving device 130, the sound conducting member 110 includes a plurality of independent mutually non-communicating closed hole structures, and a sound resonance effect And transmits sound waves of fine movement such as heart sound, respiration vibration, organ sound, etc. to the sound conducting member 110 when directly or indirectly touching the body of the user. The sound collecting member includes a first end portion and a second end portion 123, one of which contacts the surface of the sound conducting member 110 and communicates with the second end portion 123 through a through hole. The sound source receiving apparatus 130 includes a receiving end 132 and a sensor element, and the receiving end 132 is connected to the second end 123 of the sound collecting member, receives sound waves emitted from the sound conducting member 110, and detects a physiological signal.(FIG.【課題】操作が簡単で、メンテナンスが容易であり且つ慣れ親しみやすく、これにより随時使用、リアルタイム検出、未然の事故の予防という目的が達成できる生理信号センサ装置を提供する。【解決手段】音声伝導部材110、収音部材及び音源受信装置130を含む生理信号センサ装置であって、音声伝導部材110は、複数の独立した相互に連通しない閉孔構造を含み、音共鳴効果を生成して、使用者の身体に直接または間接的に接触した際に、心臓音、呼吸振動又は臓器音などの微動の音波を音声伝導部材110に伝達する。収音部材は、第1端部及び第2端部123を含み、そのうち一つの端部が音声伝導部材110表面に接触し、第2端部123の間と貫通孔により連通している。音源受信装置130は、受信端132及びセンサ素子を含み、受信端132は収音部材の第2端部123に接続され音声伝導部材110が発する音波を受信して、生理信号を検出する。【選択図】図2
