1. An electronic device comprising:
a housing including an acoustic conduit to output a sound;
a sound output device disposed at least partially in the housing, and connected with an outside of the electronic device through the acoustic conduit;
a memory;
a sensing module configured to sense that a foreign matter is present in the acoustic conduit; and
a processor electrically connected with the sound output device and the memory,
wherein the processor is configured to:
receive sensing information indicating that a foreign matter is present in the acoustic conduit from the sensing module;
determine a plurality of frequency bands based on at least one of an intensity of a voltage used in the sound output device and a gain of an audio circuit of the sound output device;
output, through the sound output device, a liquid discharge sound including the plurality of frequency bands, which are separated from each other in a frequency domain, in response to the sensing information is received; and
maintain center frequencies of the plurality of frequency bands to be substantially fixed and change, within a specified range, sound pressures of the plurality of frequency bands, during the time that the liquid discharge sound is output.
