Abstract

본 발명은 차량의 오디오레벨 제어회로에 관한 것으로, 운전석 전방의 인스트루먼트패널(100)상에 구비되어 오디오세트의 출력레벨에 대한 자동음량조절모드를 설정하기 위한 자동음량조절버튼(20)과, 엔진이 회전수를 기초로 차속을 검출하는 차속검출부(30), 상기 오디오신호의 현출력레벨을 검출하는 오디오출력레벨검출부(70), 그 오디오출력레벨검출부(70)에 의해 검출된 현출력레벨과 상기 차속검출부(30)에 의해 검출된 현재의 차속을 기초로 상기 오디오신호의 출력레벨을 자동가변시키기 위한 오디오제어신호를 출력하는 제어부(40), 상기 오디오신호처리부(50)의 오디오출력측에 접속되어 상기 제어부(40)의 오디오제어신호에 의해 상기 오디오신호의 출력레벨을 가변시키기 위한 오디오출력조절부(80)를 갖추어 구성되어, 차속의 변화에 대해 음량조절버튼(100)에 의해 설정된 음량의 자동가변이 이루어지도록 한 것이다.The present invention relates to an audio level control circuit of a vehicle, which is provided on an instrument panel 100 in front of a driver's seat and has an automatic volume control button 20 for setting an automatic volume control mode for an output level of an audio set, and an engine. A vehicle speed detector 30 for detecting a vehicle speed based on the rotational speed, an audio output level detector 70 for detecting a current output level of the audio signal, and a current output level detected by the audio output level detector 70; A control unit 40 for outputting an audio control signal for automatically changing the output level of the audio signal based on the current vehicle speed detected by the vehicle speed detection unit 30, and connected to an audio output side of the audio signal processing unit 50 And an audio output control unit 80 for varying the output level of the audio signal according to the audio control signal of the control unit 40. The automatic adjustment of the volume set by the control button 100 is to be made.

Description

Audio level control circuit of vehicle

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명이 바람직한 예에 따른 차량의 오디오레벨 제어회로의 구성을 나타낸 도면이다.1 is a diagram showing the configuration of an audio level control circuit of a vehicle according to an embodiment of the present invention.

Claims

In a vehicle equipped with an audio signal processing means 50 for reproducing an audio signal at an output level variably set by the volume control button 10 and outputting it to the speaker device 60, on the instrument panel 100 in front of the driver's seat. An automatic volume control button 20 for setting an automatic volume control mode for the output level of the audio set, a vehicle speed detecting means 30 for detecting a vehicle speed based on an engine speed, and the audio signal On the basis of the audio output level detection means 70 for detecting the current output level, the current output level detected by the audio output level detection means 70 and the current vehicle speed detected by the vehicle speed detection means 30; A control means 40 for outputting an audio control signal for automatically changing the output level of the audio signal, and an audio control signal of the control means 40 connected to an audio output side of the audio signal processing means 50; And an audio output adjusting means (80) for varying the output level of the audio signal by a call.
