본 고안은 심벌즈 소리를 내개 하는 심벌즈 음원회로에 관한 것으로, 특히 실제 심벌즈을 사용하는 대신 간단하게 음향기기에 적용함으로써 현장감있고 다이나믹한 심벌즈 소리를 낼 수 있게 한 심벌즈 음원회로에 관한 것이다.The present invention relates to a cymbal sound source circuit that emits cymbal sounds, and more particularly, to a cymbal sound source circuit capable of producing a realistic and dynamic cymbal sound by simply applying it to an audio device instead of using actual cymbals.

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 심벌즈에서 나는 소리를 대신하는 소리가 없어 실제 심벌즈를 사용해야만 하는 단점이 있었다. 이때 녹음된 심벌즈 소리를 사용하기도 하나 이는 음악의 흐름에 따라 자유자재로 적시에 사용하는데에 많은 불편이 있게되는 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 is only a melody of music, which has the disadvantage of having to use real cymbals because there is no sound replacing percussion instruments, especially cymbals that appear in the background of music performance. In this case, the recorded cymbal sound may be used, but this is disadvantageous in that there is much inconvenience in using timely and freely according to the flow of music.

본 고안은 종래의 단점을 감안하여, 실제 심벌즈 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 is made in consideration of the disadvantages of the prior art, by making a signal having the same frequency as the actual cymbal sound and reproduced through the sound equipment to be easily substituted for live music, described in detail by the accompanying drawings as follows. .

펄스입력단자(Pi)는 다이오드(D1)를 통해 전원저항(R1), (R2)의 접속점에 접속하고 그 접속점을 콘덴서(C1) 및 저항(R3)으로 구성된 미분회로부(1), 다이오드(D2), (D3)로 구성된 리미터회로부(2), 다이오드(D4), 접지콘덴서(C2) 및 저항(R4)을 통해 트랜지스터(TR1)의 베이스에 접속하여 그의 콜렉터는 콘덴서(C6), 가변코일(L1)로 구성된 고역필터부(4) 및 콘덴서(C7)를 통해 출력신호단자(So)에 접속하며, 또한 트랜지스터(TR2)의 에미터는 콘덴서(C3) 및 저항(R6)을 통해 저항(R7), (R8) 및 트랜지스터(TR3)로 구성된 증폭회로부(3), 콘덴서(C4), 가변저항(VR1) 및 콘덴서(C5)를 통해 상기 트랜지스터(TR1)의 베이스에 접속하여 구성된 것으로, 도면의 미설명부호 Vcc는 전원단자이다.The pulse input terminal Pi is connected to the connection points of the power resistors R 1 and R 2 through the diode D 1 , and the differential point circuit part 1 is formed of a capacitor C 1 and a resistor R 3 . ), Via the limiter circuit section 2 consisting of a diode (D 2 ), (D 3 ), a diode (D 4 ), a ground capacitor (C 2 ) and a resistor (R 4 ) to the base of the transistor (TR 1 ) Its collector is connected to the output signal terminal So via a condenser C 6 , a high pass filter 4 composed of a variable coil L 1 and a condenser C 7 , and the emitter of the transistor TR 2 Amplifying circuit section 3 consisting of resistors R 7 , R 8 , and transistor TR 3 , capacitor C 4 , variable resistor VR 1 , via capacitor C 3 and resistor R 6 , and The capacitor C 5 is connected to the base of the transistor TR 1 , and reference numeral Vcc in the figure represents a power supply terminal.

이와 같이 구성한 본고안의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described in detail as follows.

전원단자(Vcc)에 전원을 인가한 후 펄스입력단자(Pi)를 통해 제2도 (a)에 도시한 바와 같은 구형펄스를 인가하면 그 펄스는 미분회로(1)를 통해 제2도 (b)에 도시한 바와 같은 신호로 미분되고 이 미분된 신호는 리미터회로부(2)에서 일정치 이상의 신호 성분이 커트된 후 다이오드(D4)를 통해 제2도 (c)에 도시한 바와 같은 신호로 정류되며, 이 정류신호는 콘덴서(C2)에 충전됨과 아울러 이 충전전하가 저항(R4)을 통해 트랜지스터(TR1)의 베이스에 인가되게 되어 트랜지스터(TR1)가 온상태로 된다.After applying power to the power supply terminal Vcc and applying a rectangular pulse as shown in FIG. 2 (a) through the pulse input terminal Pi, the pulse is transmitted through the differential circuit 1 to FIG. ) into a signal and a differential in signals is a differential signal as shown in the limiter circuit (2) FIG. 2 (c) through after diode (D 4), the days or more signal component value cut in as shown in The rectified signal is charged to the capacitor C 2 , and the charging charge is applied to the base of the transistor TR 1 through the resistor R 4 , thereby turning on the transistor TR 1 .

이때 트랜지스터(TR4)의 에미터와 베이스간에는 역방향 전압이 인가되고 있으므로 그의 에미터에는 제2도 (d)에 도시한 바와 같은 잡음신호가 발생되고, 이 발생된 신호는 콘덴서(C3) 및 저항(R6)을 통해 증폭회로부(3)에 입력되어 제2도의 (e)에 도시한 바와 같은 파형으로 중폭 출력되며, 이출력신호는 콘덴서(C4)를 통하고 가변저항(VR1)을 통해 신호의 크기가 일정크기로 조정되어 콘덴서(C5)를 통해 트랜지스터(TR1)의 베이스에 인가된다. 이때 트랜지스터(TR1)가 상기 입력펄스신호에 의해 온상태에 있으므로 트랜지스터(TR1)의 베이스에 인가된 잡음신호는 트랜지스터(TR1)의 콜렉터를 통해 증폭 출력되게 되고, 이 신호는 고역필터부(4)를 통해 필터링된 후 콘덴서(C7)를 통해 출력된다(제2도의 (f)). 이때 출력신호[제2도의 (f)]의 주파수가 심벌즈 소리의 주파수 즉 200KHz-500KHz가 되도록 고역필터부(4)의 코일(L1)의 값을 설정함으로써 출력신호를 음향기기를 통해 재현할때 실제 탬버린 소리와 같은 음향을 낼 수 있으며, 이 출력신호의 감쇠시간은 상기 다이오드(D4)를 통한 신호[제2도 (c)]가 콘덴서(C2)에 충전된 후 다이오드(D4)를 통한 신호가 약해지면 콘덴서(C2)에 충전된 전하가 트랜지스터(TR1)를 통해 방전되게 되는데 이때 방전시간이 출력신호 [제2도 (f)]의 감쇠시간이 되며 상기 가변저항(VR1)의 값을 조정함에 따라 신호의 크기를 조정할 수 있다.The transistor because (TR 4) emitter and the base between the reverse voltage is applied of its emitter, the first and second road noise signals generated as shown in (d), the generated signal is a capacitor (C 3) and It is input to the amplifying circuit section 3 through the resistor R 6 and is output in a medium width as a waveform as shown in (e) of FIG. 2, and this output signal is passed through the capacitor C 4 and the variable resistor VR 1 . The magnitude of the signal is adjusted to a predetermined size and applied to the base of the transistor TR 1 through the capacitor C 5 . At this time, because in the transistor (TR 1) on by the input pulse signal is the noise signal applied to the base of the transistor (TR 1) is to be amplified output from the collector of the transistor (TR 1), this signal is high-pass filter portion After filtering through (4), it is output through the condenser C 7 ((f) of FIG. 2). At this time, by setting the value of the coil L 1 of the high pass filter unit 4 so that the frequency of the output signal [(f) of FIG. 2) becomes the frequency of the cymbal sound, that is, 200KHz-500KHz, the output signal can be reproduced through the acoustic device. after the time may be the sound of the original tambourine sound, decay time of the output signal is charged in the signal [FIG. 2 (c)], the capacitor (c 2) through the diode (D 4) diodes (D 4 When the signal through the signal is weakened, the charge charged in the capacitor C 2 is discharged through the transistor TR 1. At this time, the discharge time becomes the decay time of the output signal [Fig. 2 (f)] and the variable resistor ( By adjusting the value of VR 1 ), the magnitude of the signal can be adjusted.

이상에서 설명한 바와 같이 본 고안은 구형펄스의 순간 최대 펄스전압으로 트랜지스터(TR1)를 통해 온상태로 하여, 역방향 전압이 걸린 트랜지스터(TR2)로부터 발생되는 잡음신호를 그 트랜지스터(TR1)를 통해 증폭하고 고역필터부(4)를 통해 필터링하여 심벌즈소리와 같은 주파수를 갖는 신호를 출력함으로써 그 신호를 음향기기를 재현할때 실제 심벌즈 소리와 같은 생생한 음향을 내는 효과가 있게 된다.As described above, the present invention is turned on through the transistor TR 1 at the instantaneous maximum pulse voltage of the spherical pulse, and the noise signal generated from the transistor TR 2 subjected to the reverse voltage is applied to the transistor TR 1 . By amplifying and filtering through the high pass filter unit 4 to output a signal having the same frequency as the cymbal sound, when the signal is reproduced in the audio device, there is an effect of producing a vivid sound like the actual cymbal sound.

결국 입력구형펄스의 최대 펄스치가 되는 순간의 최대펄스전압으로 심벌즈를 치는 것과 같은 동작이 이루어지는 것이다.As a result, an operation such as hitting a cymbal with the maximum pulse voltage at the instant of the maximum pulse value of the input rectangular pulse is performed.
