Abstract

본 발명은 수신된 음성신호의 음량이 수신자가 듣기에 지나치게 크거나 작은 경우 이를 적절한 기준음량 레벨의 음성신호로 자동조정하여 출력되도록 된 전화기용 수신장치에 관한 것으로, 소정의 전기적 신호에 실려 전송되어 온 음성신호를 수신하는 수신부와 이 수신부에 수신된 음성신호를 처리하여 출력하는 음성 IC, 이 음성 IC에 의해 검출된 음성신호를 소정 레벨로 증폭하기 위한 증폭부 및 이 증폭로부터 증폭된 음성신호를 출력하는 수화기를 갖춘 수신장치에 있어서, 소정 레벨의 고음량에 대한 전압신호를 기준레벨로 설정저장하고 있는 제1메모리 수단과, 소정 레벨의 저음량에 대한 전압신호를 기준레벨로 설정 저장하고 있는 제2메모리 수단, 상기 증폭부로부터 출력된 아날로그 음성신호를 디지탈 데이터로 변환하는 A/D 변환기, 이 A/D 변환기를 통해 변환된 상기 증폭부의 출력신호와 상기 제1 및 제2메모리에 저장된 기준레벨을 근거로 상기 증폭부에 대한 증폭제어신호 변경 설정하는 제어부, 이 제어로부터의 제어신호를 아날로그 신호로 변환하여 상기 증폭로 인가하는 D/A 변환기를 포함하여 구성된 것을 특징으로 한다.The present invention relates to a receiving apparatus for a telephone, which is configured to automatically adjust the volume of a received voice signal to a voice signal of an appropriate reference volume level when the receiver is too loud or too small for hearing. A receiver for receiving an on voice signal, a voice IC for processing and outputting a voice signal received by the receiver, an amplifier for amplifying the voice signal detected by the voice IC to a predetermined level, and a voice signal amplified from the amplification. A receiver having a receiver for outputting, comprising: first memory means for setting and storing a voltage signal for a high volume at a predetermined level as a reference level, and for storing a voltage signal for a low volume at a predetermined level at a reference level A second memory means, an A / D converter for converting an analog audio signal output from the amplifier into digital data; A control unit for changing and setting an amplification control signal for the amplifying unit based on the output signal of the amplifying unit converted through ventilation and reference levels stored in the first and second memories, and converting the control signal from the control into an analog signal It characterized in that it comprises a D / A converter applied by the amplification.
