[실시예]EXAMPLE
이하, 본 고안에 따른 개인용 컴퓨터의 음성신호합성회로에 대해 예시도면을 참조해서 상세히 설명한다.Hereinafter, a voice signal synthesis circuit of a personal computer according to the present invention will be described in detail with reference to the accompanying drawings.
제1도는 상기와 같이 구성된 본 고안의 회로도를 나타낸 것으로, 이 제1도의 회로에 대한 작용을 설명하면 다음과 같다.FIG. 1 shows a circuit diagram of the present invention configured as described above. The operation of the circuit of FIG. 1 will be described as follows.
먼저, 제1도에 도신된 음향신호발생기(1)는 음향신호발생용의 범용 집적회로(예컨대 General Instruments 회사에서 제조된 칩 : AY-3-8910, AY-3-8912)로 구성되면서 통상적으로 해당 개인용컴퓨터에 내장되어 소정의 음향신호를 발생시키게 되고, 또 제1 및 제2음성신호입력단자(2, 3)에는 예컨대 마이크라던지 카셋트등과 같은 보조음성신호 발생장치에서 발생된 음성신호가 인가되는데, 그러한 보조음성 신호발생장치로부터 발생된 음성신호는 필요에 따라 상기 제1 및 제2음성신호입력단자(2, 3)에 인가되어 개인용컴퓨터에 내장된 음향신호발생기(1)에서 발생되는 음향신호와 합성될 수 있게 된다.First, the acoustic signal generator 1 shown in FIG. 1 is composed of general-purpose integrated circuits for generating acoustic signals (for example, chips manufactured by General Instruments Corporation: AY-3-8910, AY-3-8912). The built-in personal computer generates a predetermined sound signal, and the first and second audio signal input terminals 2 and 3 have a voice signal generated from an auxiliary audio signal generator such as a microphone or a cassette. The voice signal generated from such an auxiliary voice signal generator is applied to the first and second voice signal input terminals 2 and 3 as needed to be generated by the sound signal generator 1 built in a personal computer. It can be combined with an acoustic signal.
여기서, 상기 음향신호발생기(1)에서 발생된 음향신호와 보조음성신호발생장치로 부터의 음성신호가 제1 및 제2음성신호입력단자(2, 3)에 인가되는 경우의 음성신호합성에 대해 설명한다.Here, with respect to the speech signal synthesis when the sound signal generated by the sound signal generator 1 and the sound signal from the auxiliary sound signal generator are applied to the first and second sound signal input terminals 2 and 3, respectively. Explain.
우선, 상기 음향신호발생기(1)로 부터 발생된 음향신호가 저항(R1)을 통해 음성합성회로부(5)에 구성된 연산증폭기(4)의 일측 입력단에 인가됨가 더불어 보조음성신호 발생장치로부터 발생되어 제1 및 제2음성신호입력단자(2, 3)에 인가되는 음성신호도 각각 저항(R2)과 저항(R3)을 통해 상기 연산증폭기(4)의 일측 입력단에 인가된다. 그리고, 이 제1도에 있어서 상기 제1 및 제2음성신호입력단자(2, 3)측에 설치된 저할(R6, R7)과 콘덴서(C1, C2)는 신호특성보상용으로 사용된다. 따라서, 상기 연산증폭기(4)에서는 상기 음향신호발생기(1)로 부터의 음향신호와 상기 제1 및 제2음성신호입력단자(2, 3)로 부터의 음성신호가 합성되는데, 이 경우 상기 연산증폭기(4)로 부터는 다음의 식으로 표시되는 합성신호가 출력된다.First, the sound signal generated from the sound signal generator 1 is applied to one input terminal of the operational amplifier 4 configured in the voice synthesis circuit unit 5 through the resistor R1 and is generated from the auxiliary sound signal generator. Audio signals applied to the first and second audio signal input terminals 2 and 3 are also applied to one input terminal of the operational amplifier 4 through resistors R2 and R3, respectively. In FIG. 1, the drop R6 and R7 and the condensers C1 and C2 provided on the side of the first and second audio signal input terminals 2 and 3 are used for signal characteristic compensation. Accordingly, in the operational amplifier 4, the sound signal from the sound signal generator 1 and the sound signals from the first and second sound signal input terminals 2 and 3 are synthesized. From the amplifier 4, a synthesized signal expressed by the following equation is output.
단 V0는 연산증폭기(4)의 합성음성신호출력, VI1은 음향신호발생기(1)의 음향신호 출력, VI2는 제1음성신호입력단자(2)를 통해 인가되는 음성신호입력.Where V0 is a synthesized voice signal output of the operational amplifier 4, VI1 is a sound signal output of the sound signal generator 1, and VI2 is a voice signal input applied through the first voice signal input terminal 2.
VI3는 제2음성신호입력단자(3)를 통해 인가되는 음성신호 입력.VI3 is a voice signal input applied through the second voice signal input terminal (3).
이어, 상기 식으로 표시되는 연산증폭기(4)로 부터의 합성신호는 커플링콘덴서(C3)를 매개해서 음성증폭회로부(7)에 구성된 연산증폭기(6)에 인가되어 증폭되는데, 이 경우 연산증폭기(6)에서는 저항(R8, R9)의 비율에 의해 상기 음성합성회로부(5)로 부터 인가되는 합성음성신호를 증폭시키게 된다. 그후 연산증폭기(6)에서 증폭된 합성음성신호는 커플링콘덴서(C7)를 통해 모니터용 음성출력회로부(8)를 통해 전용모니터로 출력되거나, 또는 TV용 영상 및 음성신호변조기(9)를 통해 TV용 영상 및 읍성신호로 변조되어 TV수상기로 출력된다.Subsequently, the synthesized signal from the operational amplifier 4 represented by the above equation is applied to the operational amplifier 6 configured in the voice amplifier circuit 7 via the coupling capacitor C3 and amplified. In this case, the operational amplifier In (6), the synthesized speech signal applied from the speech synthesis circuit section 5 is amplified by the ratio of the resistors R8 and R9. Thereafter, the synthesized audio signal amplified by the operational amplifier 6 is output to the dedicated monitor through the audio output circuit 8 for the monitor through the coupling capacitor C7, or through the video and audio signal modulator 9 for TV. The video is modulated with a video and a town signal for output to a TV receiver.
여기서, 상기 음성신호출력회로부(8)는 직렬접속된 저항(R12, R13)과 저항(R13)에 병렬로 접속된 콘덴서(C8)로 구성되어, 모니터연결단자(12)에 접속되는 모니터내장형 스피커라던지 별도의 스피커에 대한 입력임피던스와 음성신호의 출력임피던스를 매칭시켜서 출력신호의 반사손을 제거시키기 위해 사용된다.Here, the audio signal output circuit section 8 is composed of a resistor (R12, R13) connected in series and a capacitor (C8) connected in parallel to the resistor (R13), the monitor embedded speaker connected to the monitor connection terminal (12) It is used to eliminate the reflection loss of the output signal by matching the input impedance of the audio signal with the input impedance of the separate speaker.
또한, 상기 TV용 영상 및 음성신호변조기(9)는 TV수상기를 전용모니터대신에 사용하여 해당 개인용컴퓨터에서 처리된 정보에 관한 영상 및 음성신호를 출력시키려는 경우에, 해당 개인용 컴퓨터에서 처리되는 영상 및 음성신호를 변조시켜 TV에 공급해주도록 된 범용의 TV용 영상 및 음성신호변조기(예컨대 ASTEC회사에서 제조된 변조기 : UM 1285-8)로 구성되면서, 통상적으로 해당 개인용컴퓨터에 내장되어 그 개인용컴퓨터로부터 영상신호 입력단자(10)를 통해 입력되는 영상신호와 상기 음성증폭회로부(7)로 부터 인가되는 음성신호를 변조해서 TV수상기 연결단자(11)를 통해 TV수상기로 공급해주게 된다.In addition, the TV video and audio signal modulator 9 uses a TV receiver instead of a dedicated monitor to output video and audio signals related to information processed by the personal computer. It consists of a universal TV video and audio signal modulator (e.g., a modulator manufactured by ASTEC: UM 1285-8) that modulates an audio signal and supplies it to a TV. The video signal input through the signal input terminal 10 and the audio signal applied from the audio amplification circuit unit 7 are modulated and supplied to the TV receiver through the TV receiver connecting terminal 11.
다음에 개인용컴퓨터에 내장된 음향신호발생기(1)에서 발생된 음향신호에 대해서만 설명하면, 상기 음향신호발생기(1)에서 발생되어 출력되는 음향신호는 음성신호합성회로부(5)의 입력단에 설치된 저항(R1)을 통해 연산증폭기(4)의 일단에 인가되고, 이 연산증폭기(1)에 입력된 음향신호는 상기한 식에 기초해서 저항(R1)과 저항(R4)이 비율에 따라 출력레벨이 결정되어진 다음에 커플링콘덴서(C3)를 통해 음성증폭회로부(7)로 출력된다. 이어, 이 음성증폭회로부(7)에 입력된 음향신호는 저항(R8)과 저항(R9)의 비율에 의해서 증폭되고, 그후 연산증폭기(6)에서 출력된 음향신호는 커플링콘덴서(C7)를 통해 모니터용 음성신호출력회로부(8)또는 TV용 영상 및 음성신호변조기(9)를 통해 외부로 출력된다.Next, only the sound signals generated by the sound signal generator 1 built in the personal computer will be described. The sound signals generated and output from the sound signal generator 1 are provided at the input terminal of the sound signal synthesis circuit section 5. An acoustic signal applied to one end of the operational amplifier 4 through R1 and input to the operational amplifier 1 has an output level in accordance with the ratio between the resistances R1 and R4 based on the above equation. After it is determined, it is output to the voice amplifier circuit 7 through the coupling capacitor C3. Subsequently, the sound signal input to the voice amplifier circuit 7 is amplified by the ratio of the resistor R8 and the resistor R9, and then the acoustic signal output from the operational amplifier 6 receives the coupling capacitor C7. Through the monitor audio signal output circuit unit 8 or the video and audio signal modulator 9 for TV is output to the outside.
그리고, 상기 음향신호발생기(1)로 부터의 음향신호와 상기 제1 및 제2음성신호입력단자(2, 3)중 어느 하나의 입력단자에 인가되어 음성신호를 합성시키는 경우에도 상기와 유사한 동작에 의해 합성음성신호를 얻을수 있다.The operation similar to the above is also performed when the sound signal from the sound signal generator 1 is applied to any one of the first and second sound signal input terminals 2 and 3 to synthesize the sound signal. The synthesized speech signal can be obtained by

You can use it to create a variety of sound effects, such as musical accompaniment.
