Beschreibung
Zusammenfassung:	The present invention relates to a vehicle loudspeaker system, comprising: at least two microphones forming a microphone array; at least one loudspeaker configured to emit non-human sound; and a processor programmed to receive incoming audio signals from the microphone array. The processor is further programmed to apply beam shaping to the input audio signals, determine whether a human-generated sound is detected within the audio signal, and if a human-generated sound is detected, instruct the loudspeaker to adjust a non-human-generated sound. 마이크로폰 어레이를 형성하는 적어도 2 개의 마이크로폰, 사람이 생성하지 않은 사운드를 방출하도록 구성된 적어도 하나의 라우드 스피커, 마이크로폰 어레이로부터 착신 오디오 신호들을 수신하도록 프로그래밍된 프로세서를 포함하는, 차량 라우드 스피커 시스템. 프로세서는 입력 오디오 신호들에 빔 성형을 적용하고, 오디오 신호 내에서 사람이 생성한 사운드가 검출되는지 여부를 결정하고, 사람이 생성한 사운드가 검출되면 사람이 생성하지 않은 사운드를 조정하도록 라우드 스피커에 지시하도록 추가로 프로그래밍된다.
