Abstract
본 발명은 우퍼사운드의 온/오프시에 발생하는 교류성분으로 인한 직류레벨의 변화에 의해 야기되는 팝노이즈를 제거함으로서 우퍼절환시에 스피커의 소음발생을 방지할 수 있도록 한 우퍼사운드 장치의 팝노이즈 제거회로에 관한 것으로, 스위칭부를 이루는 트랜지스터의 콜렉터 출력과 우퍼사운드 증폭기의 입력측 사이에 콘덴서와 저항으로 구성되는 전압제어부를 부가하여 구성함으로서, 보다 양질의 사운드 출력을 실현한 것이다.The present invention eliminates pop noise caused by a change in the DC level due to an alternating current component generated on / off of a woofer sound, thereby preventing the noise of the speaker during woofer switching. The present invention relates to a removal circuit, by adding a voltage control unit composed of a capacitor and a resistor between a collector output of a transistor constituting a switching unit and an input side of a woofer sound amplifier, thereby realizing a better sound output.
