본원 고안은 어학 실습실 등에 있어서 교사의 지도 내용을 루프 안테나로 송출 학생이 수신하며 학생의 질문은 천정에 부착된 고감도 마이크 또는 학생용 헤드폰 무선송신기에 의해 전달되어 교사의 지도내용과 같이 질문 내용을 교사와 전체 학생이 들을 수 있는 자력선 유도 송신 및 무선 송, 수신방법에 의한 L/L(어학 실습실 Language Laboratory) 무선 시스템에 관한 것이다.In the present invention, the student receives the teacher's instruction through the loop antenna in the language practice room, and the student's question is transmitted by the high-sensitivity microphone or the student headphone wireless transmitter attached to the ceiling, and the question is similar to the teacher's instruction. The present invention relates to a language laboratory (L / L) wireless system using magnetic field guided transmission, wireless transmission, and reception that all students can hear.
종래에 있어서 어학 실습실의 통신 시스템을 구성함에는 학생과 교사간의 통신용 케이블을 연결한 유선 통신방식이 통상적으로 쓰이고 있으나, 별도의 증폭장치를 코오드로 연결하여 케이블상의 유도 잡음이 있을 뿐만 아니라, 케이블 및 코오드의 단선으로 인한 고장을 유발해 왔던 것이며 정전시에는 그 사용이 불가했던 것이다.Conventionally, the wired communication method connecting the communication cable between the student and the teacher is commonly used to construct a communication system of a language laboratory, but there is a noise induced on the cable by connecting a separate amplifier to a cord, and a cable and a cord It has been causing a breakdown due to the disconnection of and it was not possible to use during power outage.
더욱이 설치운영상의 복잡한 문제를 소지하였을 뿐만 아니라, 보조증폭장치, 케이블 코오드, 헤드폰 등의 여러가지 장비의 사용으로 설치 비용이 고가인 비경제성이 있었다.Moreover, not only did they have complicated installation operation problems, but there was also an inexpensive installation cost due to the use of various equipment such as auxiliary amplifiers, cable cords, and headphones.
이에 대응하여 본원 고안은 자력선 유도 송신및 무선 송, 수신 방법에 의한 무선시스템으로서 통신용 케이블이 필요없고 무선 수신장치및 송신장치를 헤드폰에 내장했으므로 코드가 없을 뿐만 아니라 종래에 케이블상의 유도 잡음이 생기지 않고 정전중에도 별도의 장치 없이 발음연습 등 그 사용이 가능하며 설치운영이 간편함으로써 고장이 없고 설치 비용이 적게 드는 경제성의 신규유용의 시스템으로서 이하 도면에 의거 더욱 구체적으로 설명한다.Correspondingly, the present invention is a wireless system based on the magnetic line induction transmission and wireless transmission and reception method, which does not require a communication cable, and since the wireless reception device and the transmission device are incorporated in the headphone, there is no code and conventionally no induced noise on the cable is generated. It is possible to use such as pronunciation practice without a separate device during power outages, and as a new useful system of economical efficiency, which is trouble-free and low installation cost due to simple installation and operation, it will be described in more detail with reference to the following drawings.
제1도는 본원 고안의 자력선 송신 주장치의 계통도로서 주장치의 송신부(6)에서는 마이크(1)에 의한음성신호(가) 또는 카세트(3)(3')…나 튜너(4)(4')(4")…등을 이용한 사용하고저 하는 전송신호를 (나) 혼합기(5)에서 전압및 전류 증폭을 하여 저주파 송신기에 의해 루프 안테나(7)에 증폭된 음성전류를 흐르게 한다.1 is a system diagram of the magnetic force line transmission main device of the present invention, and in the transmission section 6 of the main device, the audio signal (a) or the cassette (3) (3 ') by the microphone 1 is used. (B) Voltage and current amplification in the mixer (5) by using the tuner (4) (4 ') (4 "), etc. and amplified by the low frequency transmitter to the loop antenna (7). Allow negative current to flow.
루프 안테나(7)에 음성전류가 흐르면 음성신호에 따라 루프 안테나(7)에서 기전력이 발생한다.When a voice current flows through the loop antenna 7, electromotive force is generated in the loop antenna 7 according to the voice signal.
따라서 이 기전력의 역방향으로 안테나(7)의 자장이 발생하게 되고 자장의 극과극 사이에는 자력선이 분포하게 되는데 이 자력선과 수직방향으로 수신기의 안테나(7)를 설치하면 수신안테나(7)의 코아에 유도된 자력선에 의해 수신안테나(7)의 코일에 기전력이 발생한다.Therefore, the magnetic field of the antenna 7 is generated in the reverse direction of the electromotive force, and the magnetic field lines are distributed between the poles and the poles of the magnetic field. When the antenna 7 of the receiver is installed in the direction perpendicular to the magnetic field lines, the core of the receiving antenna 7 is installed. The electromotive force is generated in the coil of the receiving antenna 7 by the magnetic force line induced at.
상기한 수신안테나(7)의 코일에 유도된 음성전류를 증폭하여 수신청취하게 되는 것이다.The amplification of the voice current induced in the coil of the receiving antenna (7) is to be received.
제2도는 단말 수신측의 계통도로서 단말측에서 송신통화 하고자 할 경우 천정등에 부착된 고성능 마이크(1)에 의해 제1도에 도시한 바와같은 주장치 마이크(1)및 송신부(6)를 작동하여 루프 안테나(7)에 송신하는 방법을 나타낸 것이다.FIG. 2 is a schematic diagram of the terminal receiving side. When the terminal side wants to make a transmission call, the main microphone 1 and the transmitting unit 6 as shown in FIG. 1 are operated by the high performance microphone 1 attached to the ceiling and the like. The method of transmitting to the antenna 7 is shown.
즉 학생의 질문이 천정에 부착된 고감도 주송신부(6)로 전달되어 루프 안테나(7) 저주파 수신부(9)를 통해 다른 학생 및 교사의 헤드폰(2)의 증폭회로(8)에 전달되어 교사와 전체 학생이 들을수 있게 된다.That is, the question of the student is transmitted to the high sensitivity main transmitter 6 attached to the ceiling, and is transmitted to the amplifier circuit 8 of the headphones 2 of other students and teachers through the loop antenna 7 and the low frequency receiver 9. The whole student can listen.
제3도는 단말 자체의 무선 송신기에 의해 제1도의 주장치에서 수신한 후 루프 안테나(7)에 재송신하여 통화하는 방법을 나타낸 것이다.FIG. 3 shows a method of receiving a call at the main apparatus of FIG. 1 by a wireless transmitter of the terminal itself and then retransmitting the call to the loop antenna 7.
즉 교사의 지도내용 및 전송신호(나)는 루프안테나(7)를 통해 단말송 수신부(10)에서 수신되어 헤드폰(2)자체에 부착된 증폭회로(8)를 통해 청취할 수 있는 것이며 학생의 질문내용및 대답은 천정등에 설치한 마이크(1')를 통해 루프 안테나(7)로 단말송수신부(10)를 통해 송신되어 주송신부에서 다시 교사와 다른 학생에게 보내지게 된다. 또한 제4도 및 제5도는 본원 고안의 시스템 설치 방법으로 제4도는 천정등에 고성능 마이크(1')를 부착하여 학생과 교사간의 신호를 전달하는 것이며 제5도는 각 학생의 헤드폰(2')등에 제3도의 단말 송, 수신장치를 부설한 것이다.That is, the teacher's instructional content and the transmission signal (b) can be listened to through the amplification circuit 8 attached to the headphone 2 itself by being received at the terminal transmission receiving unit 10 through the loop antenna 7. The questions and answers are transmitted to the loop antenna 7 through the terminal transmitter / receiver 10 through the microphone 1 'installed on the ceiling, and then sent back to the teacher and other students from the main transmitter. 4 and 5 are system installation methods of the present invention, and FIG. 4 is a high performance microphone (1 ') attached to a ceiling lamp to transmit a signal between a student and a teacher, and FIG. 5 is provided to each student's headphone (2'). 3 degree terminal transmission and reception equipment is installed.
이와같은 구성및 동작을 가지는 본원 고안을 요약하면,In summary, the present invention having such a configuration and operation,
종래의 유선 통식방식의 문제점을 해결한 저주파유도 통신방법으로 실내에 설치된 루프 안테나(7')에서 발생되는 자력선을 수신부(9) 또는 단말송수신부(10)에서 무선으로 수신하는 것이며 학생들의 단말 송신을 주장치에서 수신하여 재송신 공급하는 방식으로서 그 실시용에 있어서 경제성을 겸비한 신규 유용의 고안인 것이다.This is a low frequency induction communication method that solves the problems of the conventional wired communication method. The magnetic field lines generated by the loop antenna 7 'installed indoors are wirelessly received by the receiver 9 or the terminal transmitter / receiver 10. It is a new useful design that combines economic feasibility in its implementation as a method of receiving and retransmitting the data from the main apparatus.
