Abstract

본 발명은 음향신호 선택방법에 관한 것으로, 외부입력에 상응하여 메모리에 저장되어 있는 복수개의 상대물체에 대한 음향신호가 선택부로 제공되고, 마이컴은 선택부로 제공되는 복수개의 상대물체에 대한 음향신호를 체크하여 우선순위가 있는 음향신호가 존재하면 우선순위가 있는 음향신호를 선택하고, 우선순위가 있는 음향신호가 존재하지 않으면 복수개의 상대물체에 대한 음향신호를 교대로 선택하기 위한 제어신호를 발생한다. 그 다음, 메모리로부터 제공되는 복수개의 상대물체에 대한 음향신호가 마이컴으로부터의 선택을 위한 제어신호에 의거하여 선택된 다음 D/A 변환부에서 아날로그신호 형태로 변환되어 스피커로 출력되므로써, 배경음향을 위한 채널과 돌발적인 음향을 위한 채널없이 우선순위에 따라 음향신호가 선택적으로 출력되므로, 가상현실 또는 입체음향을 위한 음향기기의 제조원가를 절감시킬 수 있을 뿐만, 아니라 음향신호 합성에 있어서 오버플로우로 인한 음질저하를 방지할 수 있도록 한 것이다.The present invention relates to a method for selecting a sound signal, wherein a sound signal for a plurality of counterparts stored in a memory corresponding to an external input is provided to the selector, and the microcomputer provides sound signals for a plurality of counterparts provided to the selector. By checking, if a sound signal with priority exists, a sound signal with priority is selected, and if a sound signal with priority does not exist, a control signal for alternately selecting sound signals for a plurality of counterparts is generated. . Then, the acoustic signals for the plurality of counterparts provided from the memory are selected based on the control signal for selection from the microcomputer and then converted into analog signals in the D / A converter to be output to the speaker, thereby providing the background sound. Since the sound signal is selectively output according to the priority without the channel and the channel for the unexpected sound, not only can reduce the manufacturing cost of the acoustic device for virtual reality or stereo sound, but also the sound quality due to the overflow in the sound signal synthesis This is to prevent degradation.

Claims (1)

복수개의 상대물체에 대한 음향신호를 스피커를 통해 출력하는 방법에 있어서, 상기 복수개의 상대물체에 대한 음향신호를 입력하여 그 중에 우선순위가 있는 음향신호가 존재하는가를 체크하는 제1단계; 상기 제1단계의 체크결과 우선순위가 있는 음향신호가 존재하면 상기 복수개의 상대물체에 대한 음향신호 중에 우선순위가 있는 음향신호를 선택하고, 상기 복수개의 상대물체에 대한 음향신호 중에 우선순위가 있는 음향신호가 없으면 상기 복수개의 상대물체에 대한 음향신호를 교대로 선택하는 제2단계; 상기 제2단계에서 선택된 음향신호를 D/A 변환하여 상기 스피커를 통해 출력하는 제3단계로 이루어진 것을 특징으로 하는 음향신호 선택방법.CLAIMS What is claimed is: 1. A method of outputting sound signals for a plurality of counterpart objects through a speaker, the method comprising: a first step of inputting sound signals for the plurality of counterpart objects and checking whether there are prioritized sound signals; If a sound signal having priority exists as a result of the check in the first step, a sound signal having a priority is selected among the sound signals for the plurality of counterpart objects, and a sound signal having a priority among the sound signals for the plurality of counterpart objects is selected. A second step of alternately selecting sound signals for the plurality of counterparts if there are no sound signals; And performing a D / A conversion on the sound signal selected in the second step and outputting the same through the speaker. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
