학습용 녹음기Learning Recorder

제1도는 통상의 녹음기 시스템의 약해도.1 is a weakness of a conventional recorder system.

제2도는 본 고안의 요부 회로도.2 is a main circuit diagram of the present invention.

제3도는 본 고안의 개전 상태의 사시도.3 is a perspective view of an open state of the present invention.

본 고안은 휴대 학습용 녹음기에 관한 것으로, 2트랙 녹음재생헤드를 사용하는 통상의 녹음기에 4트랙 녹음 재생헤드를 사용하여 휴대용 가방 중앙에 수납시키고, 양측에 스피커와 테이프 수납함을 설치하여서 된 것이다.The present invention relates to a portable learning recorder, which is a conventional recorder using a two-track recording and playback head, which is stored in the center of a carrying bag using a four-track recording and playback head, and a speaker and a tape holder are provided on both sides.

종래에도 학습용이나 노래연습용으로 2트랙 녹음재생헤드를 사용하여 녹음헤드 전방에만 소거헤드를 배설하여서 녹음 테이프의 좌·우채널을 분리시킬 수 있으므로 좌 채널은 원음을 들으면서 우 채널로 자신의 발음을 녹음한 후, 좌·우채널을 동시에 합성재생 할 수는 있었으나, 원음을 들으면서 자신의 발음을 녹음할 경우에 원음 재생헤드와 녹음재생헤드가 상호간에 서로 동작하게 되어 유도 인덕턴스가 생기므로 스피커에서 비트(bit) 음이 발생되어 원음은 잭을 사용하여 이어폰으로 들으면서 반복 녹음을 하여야만 되는 것이다.Conventionally, the 2-track recording playback head is used for learning or singing practice, so that the left and right channels of the recording tape can be separated by disposing the erasing head only in front of the recording head, so the left channel records its pronunciation with the right channel while listening to the original sound. Afterwards, the left and right channels could be synthesized at the same time, but when recording their pronunciation while listening to the original sound, the original sound playhead and the recording playhead operate with each other, resulting in induced inductance. bit) The sound is generated and the original sound must be recorded repeatedly while listening to the earphone using the jack.

본 고안은 상기와 같은 점을 감안하여 2트랙 헤드를 사용하는 공지한 녹음기에 있어서 통상의 4트랙 녹음재생헤드를 사용하여 재생헤드의 2,4번 트랙을 스위치를 통하여 ＂ON＂시에는 그라운드에 접지되게 접속시키고, 녹음헤드인 3번 트랙앞에서 소거 헤드를 장설시킨 녹음기를 휴대용 가방 중앙에 수납시키고 양측에 스피커와 테이프 수납함을 설치하여서 된 것으로 비트음을 없애도 그 사용이 편리한 것이다.In view of the above, the present invention uses a conventional four-track recording / reproducing head in a known recorder using a two-track head to switch the tracks 2 and 4 of the playback head to ground when the switch is turned ON. It is connected to the ground and stored in the center of the carrying bag with a recording head installed in front of track No. 3, which is the recording head. Speakers and tape holders are installed on both sides.

이를 첨부도면에 의하여 설명하면 다음과 같다.This will be described with reference to the accompanying drawings.

본 고안은, 통상의 녹음기는 소거헤드(6)와 녹음재생헤드(5)가 구성되어서 녹음 및 재생레버를 작동시키면 발전기(9)를 통하여 소거헤드(6)가 작동하여 테이프의 녹음된 음을 소거하면서 마이크(11)를 통한 입력신호가 녹음 및 재생앰프(10)(10')에서 증폭되어 녹음재생헤드(5)를 통하여 테이프(7)를 자화시키고, 재생시에 재생레버를 누르면 테이프(7)에서 자화된 음성신호가 녹음재생헤드(5)에서 전기적인 신호로 바뀌어서 녹음 및 재생앰프(10)(10')와 출력앰프(12)(12')에서 증폭되어 스키퍼(13)(13')에서 음성신호가 재생되는 것이다. 본 고안은 상기와 같이 구성된 2트랙헤드를 사용하는 공지한 녹음기에 있어서 통상의 4트랙녹음 재생헤드(5)를 사용하여 재생헤드의 2,4번 트랙(2)(4)를 스윗치(S1)를 통하여 ＂ON＂시에는 그라운드에 접지되게 접속시키고, 녹음헤드(3)인 3번 트랙 앞에만 소거헤드(6)를 장설시킨 녹음기를 휴대용 가방(14) 중앙에 수납시키고 양측에 스피커(13)(13')와 테이프 수납함(15)(15')을 설치하게 구성된 것이다.According to the present invention, a conventional recorder includes an erasing head 6 and a recording reproducing head 5, and when the recording and reproducing lever is operated, the erasing head 6 is operated through the generator 9 to record the recorded sound of the tape. While erasing, the input signal through the microphone 11 is amplified by the recording and reproducing amplifiers 10 and 10 'to magnetize the tape 7 through the recording / playback head 5, and when the playback lever is pressed during playback, the tape 7 The audio signal magnetized in the < RTI ID = 0.0 > is converted to an electrical signal in the recording / playback head 5, and then amplified in the recording and reproducing amplifiers 10, 10 'and the output amplifiers 12, 12'. ≪ / RTI > ), The audio signal is played back. The present invention uses a conventional four-track recording playback head 5 in a known recorder using the two-track head configured as described above to switch tracks 2 and 4 of the playback head (S 1). In the case of ON, the grounder is connected to ground, and the recorder with the erase head 6 installed only in front of track 3, the recording head 3, is stored in the center of the carrying bag 14, and the speaker 13 on both sides. 13 'and tape holders 15 and 15'.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안은 학습시나 노래연습시에 녹음 및 재생레버를 동시에 누르고 스위치(S1)를 ＂ON＂시키면 테이프(7)가 소거헤드(6)와 녹음 및 재생헤드(5)를 동시에 지나게 된다.In the present invention, when the recording and playback levers are pressed simultaneously and the switch S 1 is turned on during learning or singing practice, the tape 7 passes through the erase head 6 and the recording and playback head 5 at the same time.

이때에 4트랙녹음 및 재생헤드(5)의 2,4번 헤드(2,4)는 그라운드에 접지되어 있는 것이다. 따라서 테이프(7)에 자화되어 있는 원음은 1번 재생헤드(1)를 통하여 전기적인 신호로서 바뀌어 녹음 및 재생앰프(10')와 출력앰프(12')를 통하여 스피커(13')에 원음이 재생된다.At this time, the heads 2 and 4 of the 4 track recording and playback head 5 are grounded to the ground. Therefore, the original sound magnetized on the tape 7 is converted into an electrical signal through the first playhead 1, and the original sound is transferred to the speaker 13 'through the recording and reproducing amplifier 10' and the output amplifier 12 '. Is played.

이때에 원음을 들으면서 복습 학습 및 노래를 복습 녹음하게 되면 발전기(9)에서 소거헤드(6)를 통하여 테이프(7)에 자화된 3번 채널의 음성신호가 지워지면서 복습반복음이 마이크(11)를 통하여 녹음 및 재생앰프(10)에서 증폭되어 녹음헤드(3)에서 테이프(7)에 자화시키는 것이다.At this time, if the review and the recording of the review and listening to the original sound, the voice signal of channel 3 magnetized on the tape 7 through the erasing head 6 in the generator 9 is erased while the review gospel is the microphone 11 Amplified by the recording and playback amplifier 10 through the magnetization to the tape (7) in the recording head (3).

따라서 본 고안은 원음을 들으면서 반복녹음시에 4트랙헤드(5)의 2,4번 트랙의 헤드(2,4)를 그라운드에 접지시키어서 상호간에 작동하는 녹음 및 재생헤드(2,4)에서 발생되는 상호 인덕턴스를 최소한으로 줄일 수 있으므로 종래의 2트랙헤드에서 발생되는 비트음을 방지할 수 있어 원음을 이어폰을 사용하여 들으면서 반복 녹음을 할 필요가 없이 충실한 원음을 스피커(13')를 통하여 들을 수 있는 효과가 있는 것이다.Therefore, the present invention, in the recording and playback heads (2,4) that operate by mutually grounding the heads (2,4) of tracks 2 and 4 of the 4 track head (5) during the repeated recording while listening to the original sound. Since the mutual inductance generated can be reduced to a minimum, it is possible to prevent the beat sound generated by the conventional two-track head, so that the original sound is faithfully heard through the speaker 13 'without having to repeatedly record while listening to the original sound using earphones. It can be effective.

그리고 원음과 반복녹음된 음을 청취하고자 할 때에 재생레버를 누르면 상기와 같은 동작으로 4트랙헤드(5)의 1,3번 헤드(1,3)로서 테이프(7)에 자화된 원음과 반복음이 스피커(13)(13')로서 재생되므로 사용자가 원음과 반복음을 비교하여 학습 및 노래연습을 할 수 있으며, 스트레오 녹음을 청취시에 스위치(S1)만 ＂OFF＂시키어서 재생레버를 누르면 4트랙헤드(5)의 1,3번 재생헤드(1,3)에서 테이프에 자화된 스트레오음성신호가 상기 앰프를 통하여 스피커(13)(13')로서 청취할 수 있는 것이다.When the playback lever is pressed to listen to the original sound and the repetitively recorded sound, the original sound and the repetitive sound magnetized on the tape 7 as the heads 1 and 3 of the 4 track head 5 are operated as described above. This speaker (13, 13 ') allows the user to learn and practice songs by comparing the original sound with the repetitive sound.When listening to stereo recording, turn the switch (S 1 ) ON to turn off the playback lever. When pressed, the stereo audio signal magnetized on the tape at the first and third playback heads 1 and 3 of the 4 track heads 5 can be heard as the speakers 13 and 13 'through the amplifier.

또한 본 고안은 상기와 같은 녹음기를 휴대용 가방(14) 중앙에 수납시키고 양측에 스피커(13)(13')와 테이프수납함(15)(15')을 설치하였으므로 일반인들이 녹음기 휴대시에 편리하며 책과 테이프 등의 소도구를 모두 수납할 수 있는 것이다.In addition, the present invention accommodated the recorder as described above in the center of the carrying bag 14 and the speaker (13) (13 ') and the tape storage box (15) (15') are installed on both sides, so that the general public is convenient when carrying the recorder. And small items such as tape can be stored.

이상에서와 같이 본 고안은 원음을 들으면서 자신의 발음을 녹음하는 어학학습이나 노래연습시에 4트랙헤드를 사용하여 비트음을 줄일 수 있으므로 따로 이어폰을 사용할 필요없이 복습 녹음을 할 수 있을 뿐만 아니라 녹음기가 휴대용 가방에 수납된 구조로서 그 사용이 편리한 것이다.As described above, the present invention can reduce the beat sound by using 4 track heads in language learning or singing practice while recording the original sound while listening to the original sound. The structure is housed in a portable bag, and its use is convenient.
