Electronic device and operation method therefor

Various embodiments of the present invention pertain to an electronic device and an operation method therefor. The electronic device comprises: a housing that includes a circular upper end surface comprising a plurality of openings having a selected pattern, a flat circular lower end surface and a side surface surrounding a space between the upper end surface and the lower end surface; an audio output interface that is formed on the side surface; a power input interface that is formed on the side surface; a microphone that is located inside the housing, and that faces the openings; a wireless communication circuit; a processor that is operatively connected to the audio output interface, the power input interface, the microphone and the communication circuit; and a memory that is operatively connected to the processor, wherein the memory, when the electronic device is executed, can store instructions for the processor to receive a wake-up command through the microphone, to recognize the wake-up command, to transmit to a server information regarding reception of the wake-up command using the communication circuit, to receive a response from the server using the communication circuit, to generate a first audio signal based on the response, and to output the first audio signal using the audio output interface when the microphone is available, wherein the audio signal can be a non-language sound. Various embodiments are also possible.
