SP : 스피커SP: Speaker

본 고안은 기존 완구의 내부에 설치하여 필요에 따라 어린이가 손뼉을 친다던가 혹은 소리를 지르면 그의 신호를 콘덴서 마이크(CONDENSER MICROPHONE)로 수신하여 자동적으로 멜로디 신호를 발생하는 장치에 관한 것이다.The present invention relates to a device that is installed inside the existing toys, if the child claps or shouts as needed, the device receives the signal to the condenser microphone (CONDENSER MICROPHONE) automatically generates a melody signal.

종래의 완구에 사용되는 멜로디 신호 발생장치로는 수동 태엽식으로 기어를 동작시키므로서 기어에 장착되어 있는 울림판을 공명하게 되어 멜로디 신호를 발생하는 것이 있었으나. 이는 기구적인 구조를 사용하므로서 그의 구조가 매우 복잡함은 물론 완구제품의 부피가 커져 이로인하여 원가상승의 요인이 되었으며, 동작 또한 불안정한 문제점이 있었다.As a melody signal generator used in a conventional toy, the melody signal mounted on the gear was resonated by operating the gear by a manual winding type, thereby generating a melody signal. This is due to the mechanical structure of the structure is very complicated, as well as the volume of the toy product has become a factor of the cost increase due to this, the operation was also unstable problem.

본 고안은 종래의 제반 결점을 감안하여 콘덴서 마이크, 트랜지스터 및 IC로 된 간단한 회로 구성으로서 신뢰도가 높을뿐만 아니라 자동적을 멜로디 신호를 발생할 수 있도록 안출한 것으로 이를 첨부도면에 의하여 상술하면 다음과 같다.The present invention is a simple circuit configuration consisting of a condenser microphone, a transistor, and an IC in consideration of all the conventional drawbacks, and is designed to generate a melody signal automatically as well as high reliability.

제1도는 본 고안의 회로도로서 외부신호를 감지하는 콘덴서 마이크(MC)의 일측에 콘덴서(C1)를 통해 트랜지스터(Q1)의 베이스를 접속하고 베테리전원(B)에 저항(R1)을 통해 연결된 그의 콜렉터에 콘덴서(C2)를 통해 트랜지스터(Q2)의 베이스를 접속하고, 그의 콜렉터에는 트랜지스터(Q3)의 베이스에 접속하며, 트랜지스터(Q3)의 콜렉터에는 콘덴서(C3) 및 저항(R2)을 통해 트렌지스터(Q3)의 베이스에 접속하고, 저항(R6)을 통하여는 트랜지스터(Q4)의 베이스에 접속하고, 그의 콜렉터에는 멜로디 IC(IC1)의 입력단자(2)를 접속하고,그의 출력단자(3)에 트렌지스터(Q5)의 베이스를 접속하고 트래지스터(Q5)의 콜렉터에는 스피커(SP)에 접속하여 구성시킨다.FIG. 1 is a circuit diagram of the present invention, which connects the base of the transistor Q 1 to one side of the condenser microphone MC, which senses an external signal, through the capacitor C 1 , and connects the resistor R 1 to the battery power source B. the collector, the capacitor (C 3 of connecting the base of the transistor (Q 2) via a capacitor (C 2) to its collector and, and its collector is connected to the base of the transistor (Q 3), a transistor (Q 3) is connected via ) Is connected to the base of transistor Q 3 through resistor R 2 , and to the base of transistor Q 4 through resistor R 6 , and to the collector thereof an input of a melody IC (IC 1 ). The terminal 2 is connected, the base of the transistor Q 5 is connected to its output terminal 3, and the collector of the transistor Q 5 is connected to the speaker SP.

미설명 부호 R3, R4, R5는 저항이다.Reference numerals R 3 , R 4 , and R 5 are resistors.

이와 같이 구성된 본 고안의 적용효과를 설명하면 다음과 같다.The application effect of the present invention configured as described above is as follows.

완구를 가지고 노는 어린이가 손뼉을 친다던가 혹은 소리를 지르게 되면 완구의 외부에 장착된 콘덴서 마이크(MC)에서는 이들 신호를 감지하게 되며, 이와 같이 감지된 신호는 콘덴서(C1)를 통해 트랜지스터(Q1)의 베이스에 가해져 트랜지스터(Q1)에 의하여 증폭되고, 이 증폭된 신호는 계속하여 트랜지스터(Q2), (Q3)를 도통(ON)시키게 된다.When a child playing with a toy claps or yells, these signals are detected by a condenser microphone (MC) mounted on the outside of the toy, and the detected signals are transmitted through a capacitor (C 1 ). It is applied to the base of 1 ) and amplified by the transistor Q 1 , and this amplified signal continues to turn on the transistors Q 2 and Q 3 .

이때 트랜지스터(Q3)의 콜렉터 전류는 시간이 지연회로인 콘덴서(C3)및 저항(R2)을 통하여 트랜지스터(Q2)의 베이스에 궤환(FEED BACK)되어 흐르게 되고, 트랜지스터(Q3)가 도통(on)상태이므로 바테리 전원(B)에 저항(R5)(R6)에 의하여 분할되어 트랜지스터(Q4)의 베이스에 가해지는 전압이 저전위 상태로 되므로 트랜지스터(Q4)가 도통하게 된다.At this time, the collector current of the transistor Q 3 is fed back to the base of the transistor Q 2 through the capacitor C 3 and the resistor R 2 , which are delay circuits, and the transistor Q 3 flows. Is in the on state, and the battery Q is divided by the resistors R 5 and R 6 so that the voltage applied to the base of the transistor Q 4 is at a low potential state, so that the transistor Q 4 is turned on. Done.

따라서, 전원(B)의 트랜지스터(Q4)를 통하여 멜로디IC(IC1)의 입력단자(2)에 하이 신호상태로 인가되어 멜로디IC(IC1)가 동작되므로 그의 출력단자(3)에 하이 신호가 나타나게 되고, 이 하이신호는 스위칭 트랜지스터(Q5)를 도통시키게 되므로 그의 콜렉터에 접속된 스피커(SP)가 구동되어 상기 스피커(SP)에서는 멜로디IC에서 합서된 멜로디 신호를 발하게 되는 것이다.Therefore, the melody IC IC 1 is operated by being applied to the input terminal 2 of the melody IC IC 1 through the transistor Q 4 of the power source B, and the melody IC IC 1 is operated. The signal appears, and this high signal conducts the switching transistor Q 5 so that the speaker SP connected to the collector thereof is driven to emit the combined melody signal from the melody IC.

이상에서와 같이 동작하는 본 고안은 완구의 외부에 장착된 콘덴서 마이크를 이용하여 손뼉소리 기타 음성 신호를 감지한 후 이 감지 신호에 의하여 내부에 설치된 트랜지스터 및 멜로디 IC가 동작하여 자동적으로 멜로디 신호를 발생하므로서 완구를 가지고 노는 어린이들의 흥미를 돋구어줄뿐만 아니라 그의 구성이 간단하여 공정의 단순화 및 제품원가 절감을 꾀할 수 있는 효과도 있는 유용한 고안인 것이다.The present invention, which operates as described above, detects a finger sound or other voice signal using a condenser microphone mounted on the outside of the toy, and then the transistor and the melody IC installed therein are operated by the detection signal to automatically generate a melody signal. Therefore, it is a useful design that not only inspires the interest of children playing with the toys, but also has the effect of simplifying the process and reducing the product cost due to its simple configuration.
