Abstract
An electronic device includes a housing surrounding an exterior of the electronic device and including at least one opening, a sensor module including at least one sensor, a sound output device including sound output circuitry configured to output an acoustic-signal through the at least one opening, a memory, and a processor electrically connected to the sensor module and the sound output device, wherein the processor may be configured to: determine whether the electronic device is in a state where a foreign substance has entered into the electronic device through the at least one opening, determine whether the electronic device is in a first disposition state using the sensor module based at least on determining that the electronic device is in the state where the foreign substance has entered into the electronic device, and control the electronic device to output a specified acoustic-signal having a specified frequency band and a specified waveform through the sound output device based on the electronic device being in the first disposition state.
