Abstract

본 발명은 전자악기에 관한 것으로, 일반적으로 사용되고 사용되고 있는 종래의 전자악기 장치는 음량 조절장치가 하드웨어적인 조절장치로 되어 있어 사용자가 원할 때마다 일일이 손으로 볼륨을 조정해주어야 하는 불편이 있으며 이는 타악기들과의 공연시 수시로 음량이 변할 때마다 연주자가 음량을 계속 제어해주어야 하는 불편이 따르며 공연시에는 연주자가 타악기에 비하여 본인이 연주하는 본 악기 소리를 들을 수 없어서 별도의 모니터 스피커를 사용하는 일이 많다.The present invention relates to an electronic musical instrument, a conventional electronic musical instrument device that is used and used in general, the volume control device is a hardware control device has a inconvenience to adjust the volume by hand every time the user wants, which is percussion instruments Whenever the performance changes, the player has to control the volume continuously every time the volume changes, and during the performance, the player cannot listen to the sound of the instrument he / she is playing compared to the percussion instrument, and often uses a separate monitor speaker. .

이는 모니터 스피커를 사용하는 비용과 모니터링을 통하여 연주자가 일일이 볼륨 놉을 주절해주어야 하는 작업이 수반된다.This entails the cost of using monitor speakers and the need for the performer to control the volume knob manually through monitoring.

이에 따라서 본 발명의 목적은 상기와 같은 종래의 전자악기 구동회로에 따르는 결함을 해결하기 위하여, 외부음에 가려서 악기의 음이 상대적으로 작게 들리는 것을 막기 위하여 자동으로 볼륨의 량을 외부음의 음량에 따라서 자동으로 조절해주는 전자악기의 볼륨 자동 조절회로를 제공하는데 있다.Accordingly, it is an object of the present invention to solve the defect caused by the conventional electronic instrument driving circuit as described above, in order to prevent the sound of the instrument from being relatively small due to the external sound, the volume of the external sound is automatically adjusted to the volume of the external sound. Therefore, to provide an automatic volume control circuit for electronic instruments that automatically adjusts.

Description

Volume control circuit of electronic musical instrument

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명의 전자악기의 볼륨 자동 조절회로도, 제3도는 본 발명에 따른 아날로그 신호의 디지탈 변환 설명도.2 is a circuit automatic adjustment circuit diagram of the electronic musical instrument of the present invention, Figure 3 is a diagram illustrating the digital conversion of the analog signal according to the present invention.

Claims

Automatic volume key input unit 10 that receives a key input from the user when adjusting the automatic volume, a voice signal input unit 11 for inputting a voice signal from the outside, and a first region for separating the instrument sound and the non-instrument sound from the input signal A filter 12, a CPI 14 for outputting a command of sound source generation to perform an automatic volume control function, a memory 13 for temporarily storing voice data, and a CUI 14 in response to a sound Output through the sound source generator 15 for adjusting the mixing and envelope of the digital signal, a D / A converter 16 for converting the generated digital voice signal into an analog signal, and the D / A converter 16. And a second region filter (17) for separating an audible frequency signal from the received audio signal, and a speaker (18) for converting an electrical signal into an audible voice signal.
