Abstract

본 발명은 전자악기에서 음량을 조절하는 장치에 관한 것으로, 종래의 음량조절장치에 의하면 음량의 급격한 변화가 초래되기 쉽고 외란율 및 잡음이 커질 소지가 높기 때문에 음량조절에 신뢰성을 기하기 어려우며 음질이 저하되는 등의 문제점을 해결하기 위한 것이다.The present invention relates to a device for adjusting the volume in an electronic musical instrument, according to the conventional volume control device is likely to cause a sudden change in the volume, the disturbance rate and noise is likely to be high, so it is difficult to give reliability to the volume control and the sound quality is high. This is to solve problems such as deterioration.

본 발명은 디지탈 신호처리에 의한 증폭 및 음량조절이 가능한 서라운드 처리기(Surround Precessor Chip)를 채용하고 음량조절 정보를 CPU에서 디지탈 정보로 해독하여 서라운드 처리기의 음량조절 데이타를 갱신시켜주므로서 디지탈에 의한 아날로그 음의 음량조절을 수행하고 이에 따른 음량조절 동작의 신뢰성 확보와 외란율 및 잡음감소, 이를 통한 음질향상을 기할 수 있게 한 것이며, 오디오 기기에 적용한다.The present invention adopts a surround precessor chip capable of amplification and volume control by digital signal processing, and decodes the volume control information into digital information in the CPU, thereby updating the volume control data of the surround processor. Sound volume control is performed and the reliability of the volume control operation and the disturbance rate and noise reduction and the sound quality improvement through this are applied to the audio device.
