Abstract

PURPOSE:To eliminate the need to rewind a sound recorded magnetic tape and to improve the convenience for educational applications by using an IC memory to record and reproduce sounds and therefore reproducing the sounds in a short time just with a switch operation. CONSTITUTION:A sound recording switch 3 is operated when necessary for sound recording, and the signal is applied to a control circuit 5 via a switch control circuit 4. Under such conditions, the electromotive force generated by a reproduction head 21 or the sound signal supplied through a microphone is digitized by an ADM encoding circuit 12 through an input amplifier 14 and an input filter 13 and then written to a memory part 7 by the information of an address circuit 6. Thus the sounds are recorded. Then the signal is applied to the circuit 5 via a switch control circuit 2 with operation of a reproduction switch 1. The circuit 5 extracts the desired sound out of the part 7 by the information of the circuit 6. This extracted sound is turned into an analog sound by an ADM endecoding circuit 8 and delivered in the form of a sound signal. In such a way, the sound can be reproduced in a short time just with a switch operation by using an IC memory for recording and reproducing of sounds.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an audio device having a memory-based recording function.

BACKGROUND ART In recent years, with the development of electronics, electronic devices that output audio such as televisions, radios, and stereos have developed at a dizzying pace, and products with a wide variety of uses are now on the market.

Along with this, many methods of recording and reproducing audio have been developed, and the most popular of these is the method of recording and reproducing audio using magnetism. Media for recording and reproducing audio using magnetism include magnetic tapes, magnetic disks, magnetic drums, etc. Magnetic tapes are often used in audio equipment.

The recording/playback method using magnetic tape is RAM (Japanese eq).
) format, so in order to play the same part again,
Since this requires the operation of rewinding the magnetic tape to that # position, it is extremely troublesome and time-consuming when used for English conversation lessons.

Therefore, the present invention is aimed at eliminating such problems and making it possible to repeatedly reproduce audio with a simple operation in a lead time, and will be explained below using Figure 1.

Figure f1111 is an external view of the audio equipment with IC memory according to the embodiment of the present invention, and Figure 2 is a circuit configuration diagram.

First, when using the audio equipment with To memory of the present invention, press the recording switch 3 at the place where you want to record.
operate. This signal is applied to the control circuit 5vc via the switch control circuit 4. In such a state, the electromotive force generated by the reproduction head 21Vc or the audio signal input from the microphone passes through the input amplifier 14 and the input filter 13, and is digitized by the ADM encoding circuit 12Vc. This is determined by the information from the address circuit 6.
By writing 4# into the memory section 7, the audio is recorded.

Next, if the recorded audio is to be played back, the playback switch 1 is operated. This signal is given to the control circuit 5 via the switch control circuit 2.

Then, the control row 5 takes out the necessary audio from the memory section 7 and converts it into analog by the ADM decoding circuit 8 based on the information from the address circuit 6. This sound is transmitted to the speaker 111C via the output filter 9 and the output amplifier 10, and is output as sound.

As mentioned above, if you record and play back audio using IC memory, you can play back the audio for a short time just by operating a switch, so there is no need to rewind the recorded magnetic tape and use it for educational purposes, etc. The effect is especially great in Japan.

Note that although this embodiment has been described as simply reproducing,
If you have a means to reproduce the sound over and over again, you can listen to the same sound over and over again in a short period of time just by operating a switch, which is even more effective for English conversation lessons.
