Abstract

본 발명은 음향기기의 볼륨 업/다운 시스템에 관한 것으로서, 더욱 상세하게는 음성출력을 뮤트시키는 페이드 뮤트키를 형성시켜 음성출력을 뮤트시키되 뮤트되는 음성출력을 시간 간격을 가지고 업/다운 시킬 수 있도록 한 볼륨 페이드 업/다운 방법에 관한 것이다. 종래에는 뮤트키 입력에 따라 볼륨이 갑자기 업/다운되어 놀라는 경우가 있었다. 따라서 본 발명은 제2도에서와 같이 페이드 뮤트키 입력으로 음성신호 출력레벨을 뮤트시키고 기준의 레벨로 복귀시키되 업/다운되는 각 음성신호 출력레벨이 일정시간 간격을 가지고 업/다운 할 수 있도록 한 것이다.The present invention relates to a volume up / down system of an audio device, and more particularly, to form a fade mute key to mute a voice output so that the voice output can be muted but the muted voice output can be up / down at a time interval. One volume fade up / down method. Conventionally, the volume is suddenly up / down in response to the mute key input, which may surprise you. Accordingly, the present invention mutes the voice signal output level with the fade mute key input as shown in FIG. 2 and returns to the reference level, but allows the up / down of each voice signal output level to be up / down at a predetermined time interval. will be.

Claims (1)

업/다운키 입력을 인식한 마이콤(30)의 제어로 음성신호 출력레벨을 가변시켜 출력하는 음성신호 볼륨 가변시스템에 있어서, 가변되어진 음성신호 출력레벨과 음성신호 출력볼륨을 가변시켜 출력시키는 중에 페이드 뮤트키가 입력되면 음성신호 출력을 “O”레벨의 다운시켜 출력시키고 페이드 뮤트키가 재입력되면 “O”레벨의 음성신호 출력은 페이드 뮤트키 입력 이전의 출력레벨로 업시켜 출력시키되, 상기 업/다운되어지는 각 음성신호 출력레벨이 일정시간 간각을 가지고 업/다운되어질 수 있도록 함을 특징으로하는 볼륨 페이드 업/다운방법.In a voice signal volume variable system for varying and outputting a voice signal output level under the control of a microcomputer 30 that recognizes an up / down key input, the variable voice signal output level and the voice signal output volume are faded while being output. When the mute key is inputted, the audio signal output is turned down at the "O" level, and when the mute key is input again, the audio signal output at the "O" level is raised to the output level before the fade mute key is inputted. A volume fade up / down method, characterized in that each voice signal output level to be turned up / down can be up / down at a predetermined time interval. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
