Abstract
Description
Claims (1)
- 음향발생부(31)가 접속되는 음향접속단자(30)가 형성된 음향기기(10)를 이용한 전류분리장치에 있어서,상기 음향기기(10)에서 상기 음향접속단자(30)에 인가되는 좌측 및 우측 음성신호에서 각각 분기되어 상기 음향기기(10)의 전류를 분리하여 다수의 엘이디(LED)(LED1~LED8)를 발광시키고자 이루어진 전류분리부(21)와;상기 엘이디(LED)(LED1~LED8)를 발광시키기 위한 전류를 광 발생부(41)에 접속되는 광 발생부 접속단자(40)에 인가하는 광 구동제어부(50)와;상기 광 구동제어부(50)는 음향기기(10)에서 음성신호를 출력하기 위해 좌측 및 우측에 전달되는 전류를 각각 분기하여 평활 콘덴서(C7, C8)를 통해 비반전(+) 단자에 입력되도록 구성된 증폭기(OPM1, OPM2)와;상기 증폭기(OPM1, OPM2)의 출력단은 평활 콘덴서(C3, C5)를 통하여 스위칭 트랜지스터(Q1, Q2)의 베이스단으로 입력되도록 이루어지며, 상기 스위칭 트랜지스터(Q1, Q2)의 콜렉터단은 상기 광 발생부(41)의 내측에 형성되어 직렬연결된 다수의 상기 엘이디(LED)(LED1~LED8)의 애노드단과 접속되고 상기 애노드단에서 발광량을 조절하기 위한 가변저항(VR1, VR2)과;상기 전류분리부(21)와 광 구동제어부(50)를 상호 연결하기 위한 접속단자(22);로 이루어지는 것을 특징으로 하는 음향기기를 이용한 전류분리장치.
