Description

발진 회로 장치Oscillation circuit device

제1도는 본 고안 발진 회로장치를 설명하는 회로도.1 is a circuit diagram illustrating an oscillation circuit device of the present invention.

제2도는 작용을 도시하는 파형도.2 is a waveform diagram showing an action.

본 고안은 발진 회로장치에 관한 것으로 특히 소형의 휴대용 발진기에 관한 것이다.The present invention relates to an oscillating circuit device and in particular to a small portable oscillator.

종래의 발진장치에 있어서는 크리스탈의 압전(壓電)효과를 이용하거나 기타 유도코일과 가변콘덴서를 이용하여 공진 회로를 구성하여 요망하는 발진주파수를 얻도록 된 것이 알려져 있으나 실용적으로 사용하기에는 너무 복잡하고 고가여서 특별한 경우를 제외하고는 사용할 수가 없었다.In the conventional oscillation device, it is known to use a piezoelectric effect of a crystal or to configure a resonant circuit using other induction coils and variable capacitors to obtain a desired oscillation frequency, but it is too complicated and expensive to use practically. It could not be used except in special cases.

본 고안은 실용적으로 사용하기에 적합하도록 트랜지스터와 콘덴서로 구성하여 콘덴서의 충방전을 계속시켜서 발진하도록 안출한 것으로서 본 고안은 첨부된 도면에 따라 상술한다.The present invention is composed of a transistor and a capacitor so as to be suitable for practical use, and is designed to continuously oscillate by charging and discharging the capacitor.

제1도는 본 고안 발진 회로 장치의 회로도로서 PNP형 트랜지스터(Q1)의 에미터는 저항(R)을 통해 NPN형 트랜지스터(Q1)의 베이스에 연결되고 트랜지스터(Q1)의 베이스에는 트랜지스터(Q2)의 콜렉터가 연결되어 있다.The first turning base of a transistor (Q in the present design the oscillator circuit as the circuit diagram of device with the emitter resistance (R) of the PNP-type transistor (Q 1) connected to the base of the NPN-type transistor (Q 1) and the transistor (Q 1) 2 ) Collector of is connected.

또 트랜지스터(Q1)의 콜렉터는 음향기(L)를 통해 트랜지스터(Q2)의 에미터에 연결되면서 접지되고 트랜지스터(Q1)의 콜렉터와 트랜지스터(Q2)의 베이스 사이에는 콘덴서(C)가 연결되어서 된 것으로 도면 중 부호 B는 전원을 표시한다.In between the base of the transistor (Q 1) Collector The collector and the transistor (Q 2) of the ground as with the sounder (L) connected to the emitter of the transistor (Q 2) and the transistor (Q 1) of the capacitor (C) In the drawing, reference numeral B denotes a power source.

상기와 같은 구성으로 된 본 고안의 작용과 효과를 설명하면 PNP형 트랜지스터 (Q1)의 에미터에 전원(B)을 가하면 접지와 연결된 음향기(L)와 저항(R)을 통해 콘덴서( C)가 충전되기 시작하고 트랜지스터(Q2)의 베이스도 통전압으로 상승하게 되면 (예, 약 0.6볼트) 트랜지스터(Q2)가 도통되어 PNP형 트랜지스터(Q1)의 베이스에 접지 전압이 가해지므로 트랜지스터(Q1)는 도통된다.Referring to the operation and effect of the present invention having the configuration as described above, if the power (B) is applied to the emitter of the PNP-type transistor (Q 1 ), the capacitor (C) through the sounder (L) and the resistor (R) connected to the ground Begins to charge and the base of transistor Q 2 also rises to a supply voltage (e.g., about 0.6 volts), transistor Q 2 conducts and ground voltage is applied to the base of PNP transistor Q 1 . Q 1 is conducting.

따라서 트랜지스터(Q1)가 도통되면 에미터와 접지사이에 연결된 음향기(L)의 코일에 전류가 가해지면서 에미터의 전압은 제2도(f)에 도시한 바와 같이 순간 상승했다가 음향기(L)의 코일에 의한 열기 전류가 발생하므로 하강하여 짧은 폭의 펄스가 발생한다.Accordingly, when the transistor Q 1 is turned on, current is applied to the coil of the sounder L connected between the emitter and the ground, and the voltage of the emitter rises momentarily as shown in FIG. Open current is generated by the coil of the coil), so it falls and short pulses occur.

이와 같은 펄스의 폭은 공지와 같이 코일에 의거 정해진다. The width of such a pulse is determined based on a coil as known.

상기와 같은 짧은 폭의 펄스가 콘덴서(C)를 통해 트랜지스터(Q2)의 베이스 전단되어 트래지스터(Q2)는 불통상태가 되어 베이스에 흐르는 전류는 제2도(h)와 같이 마이너스 전위(-)로 바뀌게 된다.The short pulse as described above is sheared by the base of the transistor Q 2 through the capacitor C, and the transistor Q 2 is turned off, so that the current flowing in the base is negative potential as shown in FIG. Will change to-).

따라서 저항(R)을 통해 다시 콘덴서(C)에 다시 충전이 개시됨으로서 상술한 바의 현상이 반복되나 이때 펄스와 펄스와의 시간차는 콘덴서(C)와 저항(R)의 서정수에 따라 결정됨은 물론이면, 트랜지스터(Q2)가 도통됨으로서 트랜지스터(Q1)의 베이스에 가해지는 파형은 제2도(g)와 같은 트랜지스터(Q2)의 베이스에 가해지는 파형과는 정반대의 펄스가 가해지는 것이다.Therefore, the above-described phenomenon is repeated by recharging the capacitor C again through the resistor R, but the time difference between the pulse and the pulse is determined by the reciprocal constant of the capacitor C and the resistor R as well. When the transistor Q 2 is turned on, the waveform applied to the base of the transistor Q 1 is applied with the opposite pulse to the waveform applied to the base of the transistor Q2 as shown in FIG.

또한 음향기(L) 코일에 가해지는 펄스에 따라 발진음이 발생되는 것이며, 인간의 가청주파수를 넘은 주파수로 조정함은 당업계의 전문가라면 용이하게 조정할 수 있는 것이다.In addition, the oscillation sound is generated according to the pulse applied to the sounder (L) coil, and adjusting to a frequency exceeding the human audible frequency can be easily adjusted by those skilled in the art.

상기와 같은 본 고안은 음향기(L)코일의 인덕턴스에 의해 펄스폭을 임의 조정할 수 있으며, 또 저항(R)과 콘덴서(C)에 의해 펄스간의 간격을 조정할 수 있는 것이어서 저전압의 미세소비전력으로 발진할 수 있으므로 초음파 펄스회로로 사용하기에 적합한 고안인 것이다.According to the present invention as described above, the pulse width can be arbitrarily adjusted by the inductance of the sounder (L) coil, and the interval between the pulses can be adjusted by the resistor (R) and the capacitor (C). It is a design suitable for use as an ultrasonic pulse circuit.

즉, 본 고안의 축력측인 음향기(L)측에 발과 다이오드와 같은 것을 연결하여 완구나 부로치 등의 발광 장치로 이용할 수 있으며, 또 쥐나 모기가 싫어하는 주파수로 맞추어 놓으면 구서 또는 모기 쫓는 장치로도 이용할 수가 있는 실용적인 고안인 것이다.In other words, it can be used as a light emitting device such as a toy or a brooch by connecting a thing such as a foot and a diode to the sounder (L) side, which is the axial force side of the present invention. It is also a practical design that can be used.
