Description

키보드의 알파벳 발음장치Alphabetic Pronunciation Keyboard

제1도는 본 고안의 키보드가 있는 전면판.1 is a front panel having a keyboard of the present invention.

제2도는 키보드의 매트릭스회로.2 is a matrix circuit of a keyboard.

제3도는 본 고안의 회로도.3 is a circuit diagram of the present invention.

본원은 요즈음 어린이나 저학년이 영어알파벳을 좀더 쉽게 공부할 수 있도록 영어교육자재에 관한 것으로 특히 키보드의 자판을 선택적으로 누를때마다 알파벳이 발음되도록 한 키보드의 알파벳발음장치의 관한 것이다.The present application relates to English teaching materials so that children or lower grades can study English alphabet more easily. In particular, the present invention relates to an alphabetic phonetic apparatus of a keyboard in which an alphabet is pronounced whenever a keyboard is selectively pressed.

본 고안을 도면에 의해 상세히 설명하면 자판을 제1도에서와 같이 A.B.C--Z 순서로 배열하고 Z다음에는 재반복자판을 배열하며, 발광다이오드(D)와 스피커(SP)의 중간에 전원 ON-OFF 스위치(SW)를 설치구성하고, 자판을 제2도와 같이 매트릭스스위치화하여 기억IC의 12,13,14번 핀을 column으로 하고, 1.2.3.4-11번핀(7번핀제외)을 Low로 하여 각각 연결 접속하므로 알파벳이 발음되도록 한 것이다.When the present invention is described in detail by the drawings, the keyboard is arranged in the order ABC--Z as shown in FIG. 1, the repeating plate is arranged after Z, and the power is turned on between the light emitting diodes D and the speakers SP. Install and configure the OFF switch (SW), turn the keyboard into a matrix switch as shown in Fig. 2, and place pins 12, 13, and 14 as columns, and pins 1.2.3.4-11 (except pin 7) to low. Each letter is connected so that the alphabet is pronounced.

제3도는 본 고안의 회로도로서 동작을 설명하면 다음과 같다.3 is a circuit diagram of the present invention.

전원(V)를 ON-OFF 스위치(SW)에 의해 ON시키면 기억IC에 전원이 인가되므로 작동대기상태에 들어간다.When the power supply (V) is turned on by the ON-OFF switch (SW), power is applied to the memory IC, which enters the operating standby state.

이때 12번핀과 1번핀을 연결하면 21번핀에서 바이어스 전압이 스위치 트랜지스터(T)에 연결되어 스피커(SP)가 구동되어 기억IC에 미리 기억시킨 신호가 스피커(SP)를 통해 "A"라는 알파벳을 발음하게 된다.At this time, if pin 12 and pin 1 are connected, bias voltage is connected to switch transistor T at pin 21, and speaker SP is driven so that the signal stored in memory IC in advance is letter “A” through speaker SP. Pronunciation.

이러한 순서로 12번,13번,14번핀을 1,2,3-11번핀(7번핀제외)과 연결된 표1과 같은 알파벳 발음을 들을 수가 있다.In this order, you can hear the pronunciation of the alphabet shown in Table 1, where pins 12, 13 and 14 are connected to pins 1,2,3-11 (except pin 7).

[표 1]TABLE 1

여기서 7번핀을 접지핀이므로 제외시켰다.Here, pin 7 is excluded because it is a ground pin.

제반복이란 14번핀과 8번핀을 연결하면 알파벳이 A.B.C-Z의 순서에 의해 순차적으로 계속 반복하도록 하였다.Repeating means that if you connect pin 14 and pin 8, the alphabet is repeated continuously in the order of A.B.C-Z.

또한 알파벳이 발음될 때마다 발광다이오드(D)를 점등되도록 하므로 시각적 효과를 갖도록 하였다.In addition, since the light emitting diode D is turned on whenever the alphabet is pronounced, it has a visual effect.

이와같이 구성동작하는 본 고안은 기억IC를 이용하여 알파벳이 스피커(SP)를 통해 발음될때 마다 발광다이오드(D)가 점등되도록 구성하므로 그때그때의 발음상황을 시각적으로 확인할 수 있을 뿐만아니라 전면판이 미려하여 어린이들에게 장난감으로서 기능도 갖고있어 어린이들이 가지고 놀면서 스스로 알파벳을 익힐 수 있도록 한 것이다.The present invention, which operates as described above, is configured so that the light emitting diode (D) is turned on whenever the alphabet is pronounced through the speaker (SP) using the memory IC. It also has a function as a toy for children so that children can learn the alphabet by playing with it.

Claims (2)
