Summary:The present invention relates to a complex speaker system capable of simultaneous output of super-directional and omni-directional signals. The complex speaker system includes: a signal input unit for inputting an audio input signal to be amplified; an A/D converter for converting an analog input signal into a digital signal; a signal delay unit for delaying and outputting the omni-directional signal by a delay time of a signal output from a super-directional speaker system; a pulse width modulator for pulse-width-modulating the signal output from the signal delay unit; and an omni-directional amplifier which amplifies and outputs the pulse-width-modulated signal. 본 발명은 초지향성 스피커 시스템을 포함하는 복합스피커시스템에 있어서, 증폭시킬 오디오 입력신호를 입력하는 신호입력부; 아날로그 입력신호를 디지털신호로 변환하는 A/D 변환기; 초지향성 스피커 시스템에서 출력되는 신호의 지연된 시간만큼 무지향성 신호를 지연시켜 출력하는 신호지연부; 신호 지연신호부에서 출력된 신호를 펄스폭변호하는 펄스폭변조기; 및 펄스폭변조된 신호를 무지향증폭하여 출력하는 무지향 증폭기를 포함하는 초지향성 및 무지향성 동시 신호출력이 가능한 복합스피커시스템을 제공한다.
