Claims (3)
- 차량 실내의 각 좌석 일측에 차량의 오디오와 각각 유무선 연결되어 해당 좌석의 탑승자에게만 지향성으로 음향을 출력하여 주변 좌석의 탑승자가 청취할 수 없도록 구비되고, 상기 오디오로부터 전달되는 음향신호를 수신하는 음향수신부(11)와, 음향수신부(11)에서 수신된 음향신호를 증폭 변환하는 신호변환부(12)와, 신호변환부(12)에서 변환된 음향신호를 출력하는 음향출력부(13)와, 상기 음향수신부(11)에서 수신된 음향신호를 신호변환부(12)에 전달하기 위한 신호전달 스위치부(14)와, 탑승자의 존재여부에 따라 상기 신호전달 스위치부(14)를 온오프동작시켜 음향이 출력되도록 제어신호를 생성하는 음향출력제어부(15)를 포함하여 구성된 지향성 초음파스피커(10);
상기 지향성 초음파스피커(10)와 차량 실내에 설치된 스피커 중 어느 하나로 음향이 출력되도록 선택하고, 지향성 초음파스피커(10)를 선택한 경우에 복수개의 지향성 초음파스피커 중 어느 하나 이상을 선택하여 해당 지향성 초음파스피커로만 음향이 출력되게 하는 모드선택부(20);
차량 실내의 각 좌석 수직 천장면에 설치되어 탑승자 얼굴과의 거리를 감지하기 위한 거리센서로 구성된 거리감지수단(30);
성기 거리감지수단(30)의 감지정보를 전달받아 탑승자 얼굴과의 거리를 검출한 후 볼륨정보DB에 저장되어 있는 거리별 음향세기정보를 통해 감지된 거리에 대응하는 볼륨으로 출력되도록 음향세기를 제어하는 볼륨제어부(40);
상기 차량의 각 좌석 시트부분이나 등받이부분에 설치되어 해당 좌석에 탑승한 탑승자를 감지하여 상기 음향출력제어부(15)로 감지신호를 전달하도록 압력센서로 구성된 탑승자감지센서(50);로 이루어진 것을 특징으로 하는 차량용 지향성 음향시스템.
