An electronic device and method are disclosed. The electronic device includes a housing comprising at least one electronic component disposed within the electronic device, a first separation member configured to separate a first cavity at least partially exposed to an exterior of the electronic device through the housing from a second cavity in which the at least one electronic component is disposed; and a driver disposed in a third cavity spatially coupled with the second cavity in an interior of the housing, the driver configured to generate an air pressure differential between the second cavity and the first cavity. The method operates the device responsive to detecting a water immersion condition by outputting a sound by a speaker device, detecting the outputted sound through a microphone device, determining whether the detected sound matches a predetermined reference value and if so, operating a driver device to discharge the residual water.
