[0002]

2. Description of the Related Art A learning device for languages such as a recording / reproducing device such as a tape recorder has been conventionally known, and a typical recording / reproducing device for learning English conversation is known. This recording / playback device for learning English conversation has a repeat function that allows you to repeatedly listen to important points and a function that allows you to record your own voice over the playback sound, and is dedicated to learning various languages. It was designed for.

It is also common practice to study languages and the like using a general-purpose audio cassette tape recorder. In this case, if you try to listen to an important point repeatedly, the recording tape will be rewound and played again each time. Moreover, since one's own voice cannot be recorded again, the learning is advanced mainly by listening to the recorded voice.

[0004]

By the way, the above-mentioned recording / reproducing apparatus for exclusive use for learning English conversation is designed to enhance the learning effect by having a repeat function or the like which is not found in a general audio cassette tape recorder. ing.

Further, when learning English conversation or the like using the above-mentioned general cassette tape recorder for audio, a complicated operation is required each time in order to hear an important point, and the reproduced sound is learned. Since the voice of the learner cannot be recorded again, the learner's own voice cannot be directly heard and confirmed, and the learning effect is not improved. In addition, general audio cassette tape recorders and the like were developed for the purpose of playing music and the like, and are not designed to be repeatedly rewound and played in a very short time. There is a risk that the switch portion will be damaged by excessive switch operation, which is not preferable in terms of durability.

Therefore, the present invention was created in view of the above points, and the purpose thereof is to enable repeated learning of languages and the like with a small economical load by using a general recording / reproducing apparatus for audio or the like.

Embodiments of the present invention will now be described in detail with reference to the drawings.

First Embodiment FIG. 1 is a diagram showing the overall configuration of a first embodiment to which a remote controller with a recording / playback function of the present invention is applied.

The configuration shown in the figure shows a case where a learning device for English conversation or the like is constructed by connecting a remote controller 20 to the cassette tape recorder 10. This cassette tape recorder 10 can use a general audio device, and is connected to the remote controller 20 via an output terminal O and a remote control terminal R.

The remote controller 20 has a function of instructing the cassette tape recorder 10 which is the main body device to start and stop the reproducing operation, and a function of partially recording and reproducing the audio signal output from the output terminal O. It has an IC memory 22, an analog-digital conversion circuit (A
/ D circuit) 24, digital-analog conversion circuit (D / A
Circuit) 26, address control circuit 28, changeover switch 3
0, playback keys 40, 46, stop key 42, recording key 44
It is configured to include and.

The IC memory 22 stores the voice converted into a digital signal, and for example, a dynamic RAM or a static RAM having a capacity of several M bits is used. By increasing or decreasing the storage capacity of the IC memory 22, it becomes possible to store voice for several seconds to several minutes.

The A / D circuit 24 samples the audio signal output from the output terminal O of the cassette tape recorder 10 at a predetermined frequency and encodes each sampled audio signal into a digital signal having a predetermined bit length. As the means for digital encoding, linear encoding can be used in the simplest case, but it is desirable to combine an appropriate compression technique in order to store a voice signal for a long time due to a limited memory capacity. For example, as a general audio information compression technique, a logarithmic companding PCM system, an ADPCM system, or the like is used. The audio digital signal output from the A / D circuit 24 is input to and stored in the IC memory 22.

The D / A circuit 26 is for converting the audio digital signal read from the IC memory 22 into an analog audio signal in accordance with a predetermined conversion rule. When the above-mentioned A / D circuit 24 simply performs linear encoding, the D / A circuit 26 only needs to perform linear decoding. When audio information compression is performed, the compressed signal is expanded and then decoded to output an analog audio signal. The audio signal output from the D / A circuit 26 is input to the changeover switch 30 described later.

The changeover switch 30 outputs the audio signal output from the D / A circuit 26 (audio signal once stored in the IC memory 22) and the output terminal O of the cassette tape recorder 10.
The audio signal output from the device is input, and either one of them is selected and output. The selected and output voice signal is converted into voice by an earphone (not shown) and is uttered toward a learner such as English conversation.

The address control circuit 28 uses the IC memory 22.
Create and output the write address and read address of. For example, the address control circuit 28 is configured to include a counter, and by outputting this count value as a write address, a voice signal is stored in a continuous area of the IC memory 22. Further, by using this count value as the read address, the audio signals stored in the continuous areas are sequentially read and the D / A circuit 2 is read.

At this time, reproduced audio is output from the output terminal O of the cassette tape recorder 10 and input to the changeover switch 30 in the remote controller 20.

The changeover switch 30 performs a selection operation based on the operation status of the reproduction key 46. When the reproduction key 46 is not operated, the cassette tape recorder 10 is operated.
The audio signal input from is output to the earphone etc. as it is.

To interrupt such a normal reproducing operation, the stop key 42 may simply be operated.

(2) Recording operation for IC memory By operating the recording key 44 during the reproducing operation by the cassette tape recorder 10, this operation status is input to the A / D circuit 24 and the address control circuit 28. In response to this, the A / D circuit 24 operates the cassette tape recorder 1
The reproduced voice output from the output terminal O of 0 is taken in, the above-described sampling operation and encoding operation are performed, and a digital signal of a predetermined bit length is output for each sampling cycle. The address control circuit 28 outputs the write address of the IC memory 22 in synchronization with the operation of the A / D circuit 24, and the digital signal output from the A / D circuit 24 is written in the write address. Since this write address is updated in order, the digital audio signal output from the A / D circuit 24 can be sequentially stored in consecutive address areas.

(3) Reproducing operation from IC memory In order to read and reproduce the audio signal stored in the IC memory 22 in this way, the reproducing key 46 may be operated. The operation status of the reproduction key 46 is transmitted to the D / A circuit 26 and the address control circuit 28, and the respective operations are started.

The address control circuit 28 uses the IC memory 22.
Read addresses are sequentially output from the head address, and the audio signals stored in the IC memory 22 are sequentially read from the head address. The audio signal read from the IC memory 22 is input to the D / A circuit 26, and the decoding operation described above is started. The decoded signal (analog voice signal) is input to the changeover switch 30.

When the reproduction key 46 is operated, the changeover switch 30 selects the reproduced sound output from the D / A circuit 26 and outputs it to the earphone.
