본 발명은 톤 링거(tone ringer)에 관한 것이며, 특히 논리회로를 이용하여 발진회로를 구성한 것에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tone ringer, and more particularly to the construction of an oscillation circuit using a logic circuit.

종래에는, 전화기의 벨 신호를 발생하는데 있어서, 기계적인 벨을 사용하거나 톤 링거 전용 IC 소자를 사용함으로써 전달되는 링잉(ringing)의 감도가 좋지 않거나 원가가 많이 소요되었었다.Conventionally, in generating the bell signal of a telephone, the sensitivity of ringing transmitted by using a mechanical bell or an exclusive IC device for tone ringers has been poor or expensive.

본 발명의 목적은 상술한 기계적인 벨이나 톤 링거 전용 IC 소자를 사용하지 않고 간단한 논리회로를 이용하여 벨 신호를 마련한 것이다.An object of the present invention is to provide a bell signal using a simple logic circuit without using the above-described mechanical bell or tone ringer-specific IC elements.

전기목적을 달성하기 위해서 NAND 게이트 및 R, C 소자로 구성된 발진기, 스위칭용 트랜지스터, 브릿지 정류기 및 트리거 회로 등을 구성하여 양질의 벨 신호를 얻었는바, 첨부 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.In order to achieve the electrical purpose, a high-quality bell signal was obtained by configuring an oscillator, a switching transistor, a bridge rectifier, and a trigger circuit composed of NAND gates and R and C elements. Same as

제1도는 본 발명의 톤 링거 회로도로서, 발진기(A), 발진기(B)의 출력 결합회로(C), 스위칭회로(D), 링잉회로(E) 및 입력단 (F)로 구성된다. 발진기(A)는 NAND Gate (12, 13), 저항기(14, 15) 및 커패시터(16)으로 구성되고, 발진기(B)의 구성은 발진기(A)와 본질적으로 동일하다. 발진기(B)의 출력결합회로(C)는 트랜지스터(17), 커패시터 18로 구성되어, 발진기(B)의 출력을 발진기(A)에 결합시키는 기능을 한다. 스위칭회로(D)는 트랜지스터(10), 트랜지스터(10)의 베이스 저항기(11)로 구성되고, 발진기(A,B)의 출력을 스피커(9)에 전달한다. 링잉회로(E)는 커패시터(7), 변압기(8) 및 스피커(9)로 구성된다. 입력단 (F)는 라인 (L1), (L2)로부터 링잉신호를 받아 발진기(A)(B)에 전달하는 기능을 행하면서 동시에 본 발명의 톤 링거 회로의 동작전원을 공급하는 기능을 행하는 회로로서, 직렬연결된 링잉신호 결합용 커패시터(1) 및 저항기(2), 브릿지정류기(3), 여파용 커패시터(4), 전압안정용 제너다이오드(5) 및 발진기(A),(B) 트리거용 저항기 (6)으로 구성된다.1 is a tone ringer circuit diagram of the present invention, which is composed of an oscillator A, an output coupling circuit C of a oscillator B, a switching circuit D, a ringing circuit E, and an input terminal F. As shown in FIG. Oscillator A is composed of NAND Gates 12 and 13, resistors 14 and 15, and capacitor 16, and the configuration of oscillator B is essentially the same as oscillator A. As shown in FIG. The output coupling circuit C of the oscillator B is composed of a transistor 17 and a capacitor 18, and functions to couple the output of the oscillator B to the oscillator A. The switching circuit D is composed of a transistor 10 and a base resistor 11 of the transistor 10 and transmits the outputs of the oscillators A and B to the speaker 9. The ringing circuit E is composed of a capacitor 7, a transformer 8 and a speaker 9. The input terminal F is a circuit for receiving a ringing signal from the lines L1 and L2 and transmitting the ringing signal to the oscillators A and B while simultaneously supplying the operating power of the tone ringer circuit of the present invention. , Capacitors (1) and resistors (2), bridge rectifiers (3), filter capacitors (4), zener diodes for voltage stabilization (5) and oscillators (A), (B) triggered in series ( 6).

국선 (L1),(L2)로부터 입력단(F)에 링잉신호가 들어오면 커패시터(1), 저항기(2), 브릿지 정류기(3)을 거쳐 정류된 전압이 커패시터(4)의 양단에 나타나고, 저항기(6)의 강하전압에 의해서 발진기(A)의 NAND 게이트(12) 및 발진기(B)의 NAND 게이트(19)에 트리거 입력을 주면, 발진기(A)에서는 저항기(14), 커패시터(16)에 의해 결정되는 주파수(500㎐)를 발생한다. 또한 발전기(B)에서도 저항기(6)에서 트리거 입력을 받아 발진기(B)가 동작, 저항기(21), 커패시터(23)에 의해 결정되는 주파수 파형이 제2도의 (1)에 표시한 바와 같은 파형이 테스트 포인트(test point) T에 나타나 트랜지스터 (17)을 구동시킨다.When the ringing signal enters the input terminal F from the trunk lines L1 and L2, the voltage rectified via the capacitor 1, the resistor 2 and the bridge rectifier 3 appears at both ends of the capacitor 4, and the resistor When the trigger input is applied to the NAND gate 12 of the oscillator A and the NAND gate 19 of the oscillator B by the drop voltage of (6), the oscillator A is provided to the resistor 14 and the capacitor 16. It generates a frequency (500 kHz) determined by. The generator B also receives a trigger input from the resistor 6 so that the oscillator B operates, and the frequency waveform determined by the resistor 21 and the capacitor 23 is a waveform as shown in (1) of FIG. This test point appears at test point T to drive transistor 17.

트랜지스터 (17)이 구동되지 않을 때에는 발진기(A)의 주파수가 저항기(14)의 저항값 커패시터(16)의 용량값에 의해 결정되고(500㎐), 트랜지스터 (17)이 구동할 때에는 커패시터 (18)이 커패시터 (16)과 병렬로 구성되므로, 발진기(A)의 주파수는 저항기(14)의 저항값×(커패시터(16)의 용량값＋커패시터(18)의 용량값)에 의해 결정(700㎐)되어 합성파형은 제2도의 (2)에 표시한 바와 같이 트랜지스터(10)에 나타나 변압기 (8)을 경유 스피커(9)를 구동한다. 즉, 국선 (L1),(L2)로부터의 링잉신호가 NAND 게이트 조합으로 이루어져 있는 발진기(A),(B)를 구동시켜 링잉신호를 스피커(9)로 내보내는 것이다.When the transistor 17 is not driven, the frequency of the oscillator A is determined by the capacitance value of the resistance value capacitor 16 of the resistor 14 (500 kHz), and when the transistor 17 is driven, the capacitor 18 ) Is configured in parallel with the capacitor 16, the frequency of the oscillator A is determined by the resistance value of the resistor 14 x (capacitance value of the capacitor 16 + capacitance value of the capacitor 18) (700 kHz). And the synthesized waveform appears on the transistor 10 as shown in (2) of FIG. 2 to drive the speaker 9 via the transformer 8. That is, the ringing signals from the trunk lines L1 and L2 are driven by the oscillators A and B, each of which is a combination of NAND gates, to send the ringing signals to the speaker 9.

상술한 바와 같이, 본원은 전화기의 벨 신호를 발생하는데 있어서 기계적인 벨이나, 톤링거 전용 IC 소자를 사용하지 않고, 간단한 논리회로를 이용, 벨 신호를 만듬으로써 음의 자연성을 유지할 뿐만 아니라, 원가절감의 효과가 있는등 유용한 발명인 것이다.As described above, the present application does not use mechanical bells or tone ringer-specific IC elements to generate the bell signal of the telephone, but maintains the naturalness of the sound by creating the bell signal by using a simple logic circuit, and the cost. It is a useful invention such as savings.
