1. An electronic device comprising:
a multi-function acoustic sensor, wherein the multi-function acoustic sensor comprising:
a plurality of sensors provided on a plate structure having a plurality of open spaces apart from each other, the plurality of sensors comprising 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 comprising:
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,
wherein the first case surface has a plurality of first holes,
wherein the plurality of first holes are formed as through holes from an exterior surface to an interior surface of the first case surface and are respectively provided at positions corresponding to the plurality of sensors; wherein the multi-function acoustic sensor further comprises a partition wall which is provided in the inner space of the case and spatially separates at least one of the plurality of sensors from another one of the plurality of sensors,
wherein each of the plurality of sensors is formed over a corresponding one of the plurality of open spaces, and wherein each of the plurality of sensors extends over the corresponding open space such that the sensor does not entirely cross the open space to leave a single gap oriented in the same direction as the at least one first hole and the at least one second hole, and the sensor is asymmetric over the open space.
