It relates to an automatic control circuit.
종래에는 스피커 일체형 모니터에 있어서, 음성의 크기를 조절하고자 할 경우 상기 스피커 일체형 모니터에 부착된 음성볼륨을 조절하거나, 음성카드가 내장된 컴퓨터의 음성볼륨조절 소프트웨어를 조절하여 음성의 크기를 적절하게 조절하였다.Conventionally, in the integrated speaker monitor, when the volume of the voice is to be adjusted, the volume of the voice is appropriately adjusted by adjusting the volume of the voice attached to the integrated speaker, or by adjusting the volume control software of a computer with a built-in voice card. It was.
그러나 종래에는 스피커 일체형 모니터의 음성증폭기의 한계에 의해 최상의 조건으로 음성을 조절하기 위해서는 모니터의 사운드 볼륨 및 음성카드가 내장된 컴퓨터의 음성볼륨조절 소프트웨어를 각각 조절해야 하는 불편한 문제점이 있었다.However, in the related art, in order to control the voice in the best condition due to the limitation of the voice amplifier of the speaker integrated monitor, there is an inconvenience of adjusting the sound volume of the monitor and the voice volume control software of the computer in which the voice card is embedded.
본 발명은 이와 같은 종래의 문제점을 해결하기 위해 컴퓨터통신을 이용하여 스피커 일체형 모니터에 부착된 음성볼륨 및 컴퓨터의 음성볼륨조절 소프트웨어를 동시에 자동으로 조절되게 하여 최상의 조건으로 음성을 청취할 수 있도록 한 것으로 첨부된 도면에 의하여 본 발명의 구성 및 작용효과를 설명하면 다음과 같다.The present invention is to solve the problems of the prior art by using a computer communication to adjust the voice volume attached to the speaker integrated monitor and the computer's voice volume control software at the same time automatically to listen to the voice in the best conditions Referring to the configuration and effect of the present invention by the accompanying drawings as follows.
도 1은 본 발명 엔코더 볼륨을 이용한 음성자동조절 구조를 보인 블록도.1 is a block diagram showing a voice automatic control structure using the present invention encoder volume.
도 2의 (A)(B)는 본 발명 엔코더볼륨스위치가 온상태에서 회전시 발생하는 펄스파형도.2A and 2B are pulse waveform diagrams generated when the encoder volume switch of the present invention is turned on.
먼저, 본 발명 엔코더 볼륨을 이용한 음성자동조절회로는 도 1에 도시된 바와 같이, 온상태에서 펄스파형이 발생하도록 회전동작하는 엔코더볼륨스위치(1)와, 상기 엔코더볼륨스위치(1)에서 발생한 펄스파형을 입력받아 AC펄스파를 DC성분으로 변환출력시키는 레벨변환기(2)와, 레벨변환기(2)에서 변환출력된 DC성분의 펄스파를 입력받아 내부 제어에 의해 입력된 펄스파가 어떠한 데이터값인지를 판단하여 SDA(Serial Data), SCL(Serial Clock)라인에 연결된 컴퓨터(4)에 인가하고 데이터값에 대응하는 펄스파형을 출력하는 마이컴(3)과, 상기 SDA, SCL라인을 통해 입력된 데이터값을 인식하여 음성볼륨소프트웨어를 조절하는 컴퓨터(4)와, 상기 마이컴(3)에서 출력된 데이터값에 대응하는 펄스파형을 입력받아 이를 DC성분으로 변환하여 음성증폭기(6)에 인가하는 A/D변환기(5)와, 상기 A/D변환기(5)에서 변환출력된 DC성분의 펄스파형을 저항(R2)을 통해 입력받아 이득을 조절하여 음성의 크기를 자동으로 조절하는 음성증폭기(6)로 구성된 것으로, 미설명부호 R1은 저항이다.First, the automatic voice control circuit using the encoder volume of the present invention, as shown in Figure 1, the encoder volume switch (1) that rotates to generate a pulse waveform in the on state, and the pulse generated from the encoder volume switch (1) The level converter 2 converts and outputs an AC pulse wave into a DC component, and the pulse wave input by the internal control by receiving the pulse wave of the DC component converted and output from the level converter 2 receives any data value. The microcomputer 3 which determines whether the signal is applied to the computer 4 connected to the SDA (Serial Data) and SCL (Serial Clock) lines and outputs a pulse waveform corresponding to the data value, and is input through the SDA and SCL lines. A computer 4 for recognizing data values and adjusting voice volume software, and a pulse waveform corresponding to the data values output from the microcomputer 3, receiving the pulse waveforms, converting them into DC components, and applying them to the voice amplifier 6. / D conversion 5 and a voice amplifier 6 that receives a pulse waveform of the DC component converted and output from the A / D converter 5 through a resistor R2 and adjusts a gain to automatically adjust the volume of the voice. In the drawing, reference numeral R1 is a resistor.
이와 같이 구성된 본 발명의 작용효과는 도 1에 도시된 바와 같이, 엔코더볼륨스위치(1)가 온된 상태에서 볼륨손잡이를 A방향 및 B방향으로 회전시키면 도 2의 (A)(B)에서와 같이 펄스파형이 발생하게 된다.As shown in FIG. 1, when the encoder volume switch 1 is turned on, the volume knob is rotated in the A and B directions as shown in FIG. Pulse waveform is generated.
즉, A방향으로 회전시키면 레벨변환기(2)를 통해 출력되는 DC성분은 증가하고, 반대로 B방향으로 회전시키면, 도 2의 (B)에서와 같이 지연시간(ㅿt)만큼 레벨변환기(2)를 통해 출력되는 DC성분은 감소하게 된다.In other words, when rotating in the A direction, the DC component output through the level converter 2 increases, and conversely, when rotating in the B direction, as shown in FIG. The DC component output through is reduced.
상기 엔코더볼륨스우치(1)에서 발생한 펄스파형이 레벨변환기(2)에 인가될 때 저항(R1)을 통해 일정전압(5V)이 인가되므로서 상기 레벨변환기(2)는 입력된 AC펄스파형을 DC성분으로 그 레벨을 변환시켜 마이컴(3)에 인가한다.When the pulse waveform generated by the encoder volume switch 1 is applied to the level converter 2, a constant voltage 5V is applied through the resistor R1, so that the level converter 2 receives the input AC pulse waveform. The level is converted to a DC component and applied to the microcomputer 3.
따라서, 마이컴(3)은 레벨변환기(2)에서 변환출력된 DC성분의 파형을 입력받아 어떤 데이터값인지를 판단한다.Therefore, the microcomputer 3 receives the waveform of the DC component converted and output from the level converter 2 and determines what data value it is.
이후 마이컴(2)은 판단된 데이터값을 SDA, SCL라인에 연결된 컴퓨터(4)에 출력하면 상기 컴퓨터(4)는 SDA, SCL라인을 통해 입력된 데이터값을 인식하여 컴퓨터(4)내부의 음성볼륨소프트웨어를 조절하게 된다.After that, when the microcomputer 2 outputs the determined data value to the computer 4 connected to the SDA and SCL lines, the computer 4 recognizes the data value input through the SDA and SCL lines, and the voice inside the computer 4 is displayed. Adjust the volume software.
그리고, 마이컴(3)은 판단된 데이터값을 컴퓨터(4)에 인가할 때 동시에 판단된 데이터값에 대응하는 펄스파형을 출력하게되면 A/D변환기(5)는 마이컴(3)에서 출력된 펄스파형을 입력받아 이를 DC성분으로 변환시켜 저항(R2)을 통해 음성증폭기(6)에 인가하므로서, 상기 음성증폭부(6)는 A/D변환기(5)에서 변환출력된 DC성분을 저항(R2)을 통해 입력받아 이득을 조절하므로서 외부에서 입력된 음성의 크기를 자동으로 조절하여 출력하게 된다.When the microcomputer 3 applies the determined data value to the computer 4 and simultaneously outputs a pulse waveform corresponding to the determined data value, the A / D converter 5 outputs the pulse output from the microcomputer 3. By receiving the waveform and converting it into a DC component and applying it to the voice amplifier 6 through the resistor R2, the voice amplifier 6 receives the DC component converted from the A / D converter 5 and outputs the resistor R2. By adjusting the gain received through), the volume of the externally input voice is automatically adjusted and output.
따라서, 사용자가 스피커일체형 모니터에서 음성을 청취할 때 음성의 크기를 조절하고자 할 경우 컴퓨터통신을 이용하여 자동으로 스피커일체형 모니터에 부착된 음성볼륨과 컴퓨터내부의 음성볼륨소프트웨어를 동시에 조절하므로서 사용자가 원하는 음성을 청취할 수 있게 된다.Therefore, if the user wants to adjust the volume of the audio when the user listens to the speaker integrated monitor, the computer can automatically adjust the voice volume attached to the speaker integrated monitor and the voice volume software inside the computer. You can listen to the voice.
이상에서 설명한 바와 같이, 컴퓨터통신을 이용하여 음성을 조절하고자 할 경우 모니터에 부착된 음성볼륨과 컴퓨터내부의 음성볼륨소프트웨어가 동시에 자동으로 조절되므로서 사용자는 항상 최적의 상태로 음성을 청취할 수 있는 효과가 있다.As described above, when the voice is to be controlled using computer communication, the voice volume attached to the monitor and the voice volume software inside the computer are automatically adjusted at the same time, so that the user can always listen to the voice in an optimal state. It works.
