본 고안은 룸바 따위의 반주용으로 두손에 잡고 마주 부딪히는 타악의 일종인 클라브스(CLAVE) 음원회로에 관한 것으로, 특히 실제 클라브스를 사용하는 대신 간단하게 음향기기에 적용함으로써 현장감있고 다이나믹한 소리를 낼 수 있게 한 클라브스 음원회로에 관한 것이다.The present invention relates to the CLAVE sound source circuit, which is a type of percussion that is held in two hands and faces each other for accompaniment such as rumba. In particular, the present invention provides a realistic and dynamic sound by simply applying it to an acoustic device instead of using actual claves. It is about the clav's sound source circuit which made it possible to produce it.
종래의 경우, 실제 악기연주에 대신하여 음향효과를 내는 것으로 에코밴드가 있어 음악연주에 간편하게 사용되었다. 그러나,이는 단지 음악의 멜로디만을 내는 것으로 음악연주의 배경으로 등장하는 타악기, 특히 클라브스에서 나는 소리를 대신하는 소리가 없어 실제 클라브스를 사용해야만 하는 단점이 있었다. 이때 녹음된 클라브스 소리를 사용하기도 하나 이는 음악의 흐름에 따라 자유자재로 적시에 사용하는데 많은 불편이 있게 되는 단점이 있다.In the conventional case, an echo band is used instead of a real musical instrument, so it is easily used for music performance. However, it only plays the melody of music, and there is no substitute for percussion that appears in the background of the music performance, especially the claves, which has to use the actual claves. In this case, the recorded clav's sound may be used, but there is a disadvantage in that there is a lot of inconvenience in using timely and freely according to the flow of music.
본 고안은 이러한 종래의 단점을 감안하여, 실제 클라브스(CLAVE) 소리와 같은 주파수를 갖는 신호를 만들어 음향기기를 통해 재현함으로써 간편하게 생음악에 대용할 수 있도록 안출한 것으로, 첨부한 도면에 의해 이를 상세히 설명하면 다음과 같다.The present invention has been made in view of the conventional disadvantages, by creating a signal having the same frequency as the actual Claves (CLAVE) sound and reproduced through a sound device to be easily substituted for live music, in detail by the accompanying drawings The explanation is as follows.
펄스입력단자(Pi)는 다이오드(D1)를 통해 저항(R1)(R2)의 접속점에 접속하고 그 접속점은 콘덴서(C1) 및 저항(R3)으로 구성된 미분회로부(1), 다이오드(D2)(D3)로 구성된 리미터회로부(2), 다이오드(D4) 및 저항(R4)을 통해 코일(L1), 콘덴서(C2-C4)등으로 구성된 공진회로부(3)의 입력측에 접속하여 그의 출력측은 가변저항(VR1)을 통해 출력신호단자(So)에 접속하여 구성한 것으로, 도면의 미설명부호 Vcc는 전원단자이다.The pulse input terminal Pi is connected to the connection point of the resistor R 1 (R 2 ) through the diode D 1 , and the connection point is a differential circuit part 1 composed of a capacitor C 1 and a resistor R 3 , Resonant circuit part composed of a coil (L 1 ), a capacitor (C 2 -C 4 ) and the like through a limiter circuit part 2 consisting of a diode (D 2 ) (D 3 ), a diode (D 4 ) and a resistor (R 4 ) The output side is connected to the input side of 3), and the output side thereof is connected to the output signal terminal So through the variable resistor VR 1 , and the reference numeral Vcc in the figure is the power supply terminal.
이와 같이 구성한 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured in this way as follows.
전원단자(Vcc)를 통해 전원이 인가된 후 펄스입력단자(Pi)를 통해 제2도 (a)에 도시한 바와 같은 구형펄스가 입력되면 이 입력펄스는 다이오드(D1)를 통해 미분회로부(1)에 입력되어 제2도 (b)에 도시한 바와 같은 파형으로 미분되게 되고, 이 미분된 펄스는 리미터회로부(2)를 통하여 일정치 이상의 신호값이 커트된후 다이오드(D4)를 통해 제2도 (c)에 도시한 바와 같은 파형으로 정류되어 공지의 공진회로부(3)의 입력되어 일정주파수로 공진된 후 가변저항(VR1)을 통해 그 크기가 결정되며 제2도 (d)에 도시한 바와 같은 파형으로 출력되게 된다.After the power is applied through the power supply terminal Vcc and the rectangular pulse as shown in FIG. 2 (a) is input through the pulse input terminal Pi, the input pulse is inputted through the diode D 1 to the differential circuit unit ( 1) is inputted and differentiated into a waveform as shown in FIG. 2 (b), and the differentiated pulse is cut through a diode D 4 after a signal value of a predetermined value or more is cut through the limiter circuit part 2. Rectified into a waveform as shown in FIG. 2 (c), inputted by a known resonant circuit unit 3, and resonated at a constant frequency, and then the magnitude thereof is determined through the variable resistor VR 1 . The waveform is output as shown in FIG.
이때, 출력신호의 주파수는 상기 공진회로부(3)의 코일(L1) 및 콘덴서(C2-C4)의 값에 따라 정해지는 바, 즉 공진주파수〔여기서, CT는 콘덴서 (C2-C4)의 합성용량치)〕가 되게 되므로 이 주파수를 클라브스 소리의 주파수와 같은 2KHz-3KHz가 되도록 코일(L1) 및 콘덴서 (C2-C5)의 값을 설정하면 출력신호〔제2도의 (d)〕는 클라브스를 마주 부딪칠때와 같은 주파수로 출력되며, 이 신호의 감쇠시간은 공진회로부(3)의 코일(L1) 및 콘덴서 (C2-C4)에 의해 결전되는 시정수, 즉〔단, 여기서 CT는 콘덴서(C2-C4)의 합성용량〕의 값에 따라 결정되어 신호는 지수적으로 감쇠하게 된다〔e-t, 여기서 t는 시간〕. 결국, 입력 구형펄스의 상승순간의 최대 펄스 전압치로 클라브스를 서로 마주치는 것과 같은 출력신호를 얻게 된다.At this time, the frequency of the output signal is determined according to the values of the coil (L 1 ) and the capacitor (C 2 -C 4 ) of the resonant circuit portion 3, that is, the resonant frequency Where C T is the combined capacitance of the condenser (C 2 -C 4 ), so that the frequency is 2 KHz-3KHz equal to the frequency of the clav's sound and the coil L 1 and the condenser (C 2 -C). 5 ), the output signal [(d) of FIG. 2] is output at the same frequency as when it strikes the claves, and the decay time of the signal is the coil L 1 and the condenser of the resonance circuit section 3. The time constant determined by (C 2 -C 4 ), ie Where C T is determined according to the value of the combined capacitance of the capacitors C 2 -C 4 so that the signal is exponentially attenuated. t, where t is time]. As a result, an output signal is obtained such that the clabs face each other with the maximum pulse voltage value of the rising moment of the input rectangular pulse.
이상에서 설명한 바와 같이 본 고안은 입력 구형펄스의 상승순간의 최대 전압치를 이용하여 공진회로부(3)를 통해 일정주파수로 공진시켜 출력시킴으로써 클라브스에서 나는 소리와 같은 음향효과를 내는 주파수를 얻게되는 효과가 있는 것이다.As described above, the present invention uses the maximum voltage value of the rising instant of the input spherical pulse to resonate and output at a constant frequency through the resonant circuit unit 3, thereby obtaining a frequency that produces an acoustic effect such as the sound of the clav's. There is.
