Abstract
According to various embodiments of the disclosure, an electronic device may include 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, and a processor electrically connected with the sound output device and the memory. The processor may determine whether specified information is received in association with an output of the sound output device, output, through the sound output device, a sound including a plurality of frequency bands, based on the specified information, when the specified information is received, and maintain center frequencies of the plurality of frequency bands to be substantially fixed and change, in a specified range, sound pressures of the plurality of frequency bands, during time that the sound is output.
