Abstract
Description
Claims (1)
- 각종 음성신호를 복조하여 출력하는 코덱과, 상기 코덱의 음성 복조기능에 대한 동작을 제어하는 CPU와, 사용자 인터페이스를 제어하는 마이콤과, 상기 코덱을 통해 복조되어 인가되는 각 출력 음성신호를 믹싱하는 믹서와, 믹서의 출력을 설정된 레벨로 증폭하는 AMP 및 증폭된 음성신호를 음량으로 출력하는 스피커를 포함하는 차량정보 단말기에 있어서,상기 코덱의 각 채널에서 인가되는 MP3, 핸즈프리, 네비게이션 정보의 출력을 선택 결정하며, 볼륨 조절 노브의 음량 출력 조정값에 따라 음량 출력 레벨을 실시간으로 조정하고, 임의의 음성신호에 대한 출력을 유지하는 상태에서 코덱에서 다른 음성 출력이 인가되면 각기 다른 두개의 음성이 동시에 출력되도록 하는 전자볼륨 및 라인 스위치를 더 포함하는 것을 특징으로 하는 차량정보 단말기의 음량 조절장치.
