Provided is an acoustic sensor device which, for confirming the location of a missing person, is airdropped from a drone, lands on the ground and collects and transmits a sound event. The acoustic sensor device according to an embodiment of the present invention comprises: a device body which stands upright without toppling over even when tilted after being airdropped from a drone, and collects sound information; and a parachute coupling releasing apparatus connected to the device body and coupled to or released from a parachute in accordance with whether or not the weight of the device body is applied. Therefore, the present invention is prevented from bouncing upon landing and can collect sound information while standing upright without toppling over even when tilted, thereby contributing to a work for confirming the location of a missing person. L'invention concerne un dispositif de capteur acoustique qui, afin de confirmer l'emplacement d'une personne disparue, est largué depuis un drone, atterrit sur le sol et collecte et transmet un événement sonore. Le dispositif de capteur acoustique selon un mode de réalisation de la présente invention comprend : un corps de dispositif qui se dresse verticalement sans basculement même lorsqu'il est incliné après avoir été largué depuis un drone, et collecte des informations sonores ; et un appareil de libération de couplage de parachute relié au corps de dispositif et couplé à un parachute ou libéré par ce dernier selon que le poids du corps de dispositif est appliqué ou non. Ainsi, la présente invention est empêchée de rebondir lors de l'atterrissage et peut collecter des informations sonores en se dressant verticalement sans basculement même lorsqu'elle est inclinée, ce qui contribue à un travail de confirmation d'emplacement d'une personne disparue. 조난자 위치 확인을 위하여, 드론에서 투하되면, 지상으로 착지하여 음향 이벤트를 수집하여 전송하는 음향센서 디바이스가 제공된다. 본 발명의 실시예에 따른 음향센서 디바이스는, 드론에서 투하되면, 기울어지더라도 쓰러지지 않고 직립한 상태로, 음향 정보를 수집하는 디바이스 본체; 및 디바이스 본체에 연결되되, 디바이스 본체 무게의 작용 여부에 따라 낙하산과 결속 상태 또는 결속 해제 상태가 되는 낙하산 결속 해제 장치;를 포함한다. 이에 의해, 착지 시 바운스되는 것을 방지하고, 기울어지더라도 쓰러지지 않고 직립한 상태로, 음향 정보를 수집할 수 있어, 조난자 위치 확인 작업에 기여할 수 있다.
