Abstract

본 발명은 자동 음량 제어 장치에 관한 것으로, 외부의 소음정도를 측정하는 소음측정부와 청취자들이 청취하기에 가장 적당한 음량이 전기적신호로 설정되어 있는 음량설정부와, 상기 음량설정부의 출력신호와 상기소음측정부의 출력신호를 더하여 주는 합산부와, 통산적인 음성신호 전송장치로 부터 전송되는 음성정보가 실린 전기적신호가 입력하는 신호입력부와, 상기 신호입력부의 출력신호를 증폭하는 증폭부와, 상기 증폭부의 출력신호와 상기 합산부의 출력신호를 비교하여 그 비교된 신호값을 제어부로 출력하는 비교부와, 상기 비교부로 부터 출력하는 비교신호에 따라 음량조절부를 제어하는 제어부와, 상기 증폭부에서 출력하는 전기적신호를 음성신호로 변환하여 음량조절부로 전송하는 변환부와, 상기 제어부의 제어의 의해 상기 변환부로 부터 입력하는 음성신호의 음량을 조절하는 음량조절부와, 상기 음량조절부에서 음량이 조절된 음성신호를 송출하는 스피커를 포함하고 이루어져, 주위소음의 정도에 따라 스피커에서 송출되는 음량을 자동으로 조절하여 주기 때문에 주위소음의 강약에 관계없이 청취자가 음량이 너무커서 불쾌감을 느끼거나 음량이 너무 작아 음성정보의 내용을 듣지 못하게 되는 등의 불편함이 없이 적당한 음량으로 청취할 수 있고, 또한, 청취자가 직접 음량을 조절해야 하는 불편함을 없애도록 한 것이다.The present invention relates to an automatic volume control device, comprising: a noise measuring unit for measuring an external noise level, a volume setting unit for setting a sound volume most suitable for a listener to listen to, an output signal of the volume setting unit, and A summation unit for adding an output signal of the noise measuring unit, a signal input unit for inputting an electrical signal containing voice information transmitted from a general voice signal transmission device, an amplifying unit for amplifying an output signal of the signal input unit, and the amplification unit; A comparison unit for comparing a negative output signal with an output signal of the summing unit and outputting the compared signal value to a control unit, a control unit controlling a volume control unit according to a comparison signal output from the comparison unit, and outputting from the amplifying unit A conversion unit for converting an electrical signal into a voice signal and transmitting the same to a volume control unit; It includes a volume control unit for adjusting the volume of the audio signal input from the negative portion, and a speaker for transmitting a voice signal of which the volume is adjusted in the volume control unit, and automatically adjusts the volume emitted from the speaker according to the degree of ambient noise This allows the listener to listen at an appropriate volume without any inconvenience, such as being uncomfortable because the volume is too loud or uncomfortable because the volume is too low to hear the contents of the voice information. To eliminate the inconvenience of manually adjusting the volume.
