Multi-function acoustic sensor

Abstract

A multi-function acoustic sensor may include a plate structure having a plurality of open spaces that are spaced apart from each other; a plurality of sensors provided on the plate structure, the plurality of sensors including a plurality of sensor elements respectively provided to overlap the plurality of open spaces; and a case having an inner space in which the plurality of sensors are provided, the case including: a first case surface on which the plurality of sensors are provided, the first case surface having at least one first hole, and a second case surface opposite to the first case surface, the second case surface having at least one second hole, wherein the at least one first hole and the at least one second hole form at least one path along which sound is transmitted and sensed through at least one of the plurality of open spaces of the plate structure.
