Abstract

본 발명은 링거신호와 온후크다이얼(OHD)시 스피커음량 및 수화기 스피커의 음량을 별도로 여러개의 음량조절수단을 사용하지 않고 간단한 업·다움 버튼만으로 편리하게 조잘할 수가 있도록 된 전화기의 음량조절회로 및 방법에 관한 것으로 업·다움 버튼만으로 링거신호와 온후크다이얼시 스피커음량 및 수화기 스피커의 음량을 간편하게 조절할 수 있다.The present invention provides a volume control circuit of a telephone that enables the user to conveniently adjust the volume of the speaker and ringer signal at the time of ringer signal and on hook dial (OHD) by using a simple up / down button without using a separate volume control means. The up and down buttons can be used to adjust the volume of the ringer signal, speaker volume at the time of on hook dial, and the volume of the receiver speaker.

Description

전화기의 음량조절회로 및 방법Volume control circuit and method of telephone
