Zusammenfassung:An electronic device according to one embodiment may comprise: a plurality of microphones disposed at different locations in the electronic device; a processor that collects input signals inputted to each microphone, obtains DOA information corresponding to each microphone from the input signals, calculates the directions of occurrence of the input signals using the DOA information, adjusts a weight of the input signal for each microphone based on the directions of occurrence of the input signals, and generates output signals for each microphone by reflecting the weight adjusted for each microphone; and a speaker that outputs output signals for each microphone. Therefore, the present invention is capable of removing directional noise. 일 실시예에 따른 전자 장치는 전자 장치에서 상이한 위치들에 배치된 복수의 마이크들, 마이크들 각각에 입력되는 입력 신호들을 수집하고, 입력 신호들로부터 마이크들 각각에 대응하는 DOA 정보를 획득하고, DOA 정보를 이용하여 입력 신호들의 발생 방향들을 산출하고, 입력 신호들의 발생 방향들에 기초하여 마이크들 별 입력 신호의 가중치를 조절하고, 마이크들 별로 조절된 가중치를 반영하여 마이크들 별 출력 신호를 생성하는 프로세서, 및 마이크들 별 출력 신호를 출력하는 스피커를 포함할 수 있다.
