The present invention relates to a reproducing apparatus such as a compact disc player, a video cassette recorder, an audio tape recorder, and the like, which reproduces signals recorded on a recording medium such as an optical disc and a magnetic tape, and repeatedly outputs audio signals of a predetermined section reproduced on a magnetic medium. The present invention relates to a repetitive output device and a method for outputting a voice signal, and in particular, to store a voice signal in a predetermined section in a memory, and to output the voice signal repeatedly to continuously output the voice signal without interruption. An apparatus and an output method are provided.

Conventionally, as shown in FIG. 1, when a repetition section for repeatedly outputting an audio signal is set, it is determined whether the repetition section is a start position of the set recording medium, and when the repetition section is not the start position, the recording medium is reversely played back to the start position. When it reaches the start position, it reproduces the repeating section and outputs the audio signal while judging whether it is the end position of the repeat section. The replaying operation was repeated after reverse playback to the start of the section.

However, in the conventional technology as described above, when the audio signal of the repeating section set by the user is repeatedly output, the operation of reverse playback → playback → reverse playback of the recording medium must be repeated. There was a problem that it was not necessary to repeatedly output the audio signal of the repetition section set due to an error such as slippage of the recording medium, causing inconvenience to the user and degrading the reliability of the product.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned general problems, and converts a voice signal of a repetition section set by a user into a digital signal and stores it sequentially in a memory, and sets a voice digital signal stored in the memory. The repetitive output device and output which sequentially reads the repetition section and outputs it by converting it into analog signal and outputting the repetitive section of the audio signal without waiting. The object of the present invention is to provide a method, which will be described in detail with reference to the accompanying drawings of FIGS. 2 to 4.

2 is a circuit diagram showing the configuration of a repeating output device of the present invention. As shown therein, a separate voice recording / playback memory 1 is provided to record and repeat playback from and to the memory 1. In the audio signal repeating output device configured to be capable of performing the above, an analog / digital converter (2) for digitally converting audio signals output from the memory (1) and the digitally converted audio signal are recorded and stored in the memory (1). The control logic unit 3 controls the repetitive reproduction from the memory 1, and controls the control unit 5 according to an external input key which is a recording section setting and a repetition reproducing frequency setting key for the voice repetitive reproducing operation. Accordingly, only the audio signal is passed through the digital / analog converter 5 for analog-converting the audio signal reproduced from the memory 1 and the output signal of the digital / analog converter 5. It was composed of a low-pass filter (6).

The repetitive output device of the present invention configured as described above reproduces the signal stored in the recording medium when the system controller 4 presses the playback key by controlling the operation of the playback device according to the key signal input by the user's key operation. The reproduced audio signal is converted into a digital signal by the analog / digital converter 2 and output.

In such a state, when the user rolls the start of the repetition section, the system controller 4 controls the control logic unit 3 to sequentially output the voice digital signal stored in the memory 1 for the set number of times and output the voice digital signal. Is converted into an analog signal by the digital / analog converter 5 and output through the low pass filter 6.

On the other hand, Figure 4 is a signal flow chart showing the repetitive output method of the present invention applied to a video cassette recorder. As shown in this figure, the storage address of the memory 1 when the start key of the repetition section is input in the state of the current playback mode. Set (WAD) to 0, store the audio digital signal output from the analog-to-digital converter (2) to the storage address (WAD) of the memory (1), add 1 to the storage address (WAD), and end the repetition section. It is determined whether a key is input, and the operation of storing the voice digital signal in the storage address WAD and adding 1 to the storage address WAD until the end key is input is repeated.

In this state, when the end key is input, the storage address WA D is stored in the register LREA, the stop play is performed in the stop play mode, the repetition count (LRN) is set to 0, and the read address RAD is set. It is set to 0, the voice digital signal in the read address RAD is read out to the memory 1, and after adding 1 to the read address RAD, whether the values of the read address RAD and the register LREA are the same. In other words, when the voice digital signals stored in the memory 1 are all outputted, the voice digital signals in the read address RAD are read and output, and 1 is added to the read address RAD. Repeat.

In this state, when the audio digital signals stored in the memory 1 are all output and the read address RAD is equal to the value of the register LREA, 1 is added to the repetition dimension LRN and the repetition frequency LNN. ) Is equal to the set repetition number (N), and if it is not the same, the read address RAD is set to 0, and the operation of reading and outputting the voice digital signal in the read address RAD is repeated. If (LRN) is equal to the set repetition number (N), the playback operation is performed again in the playback mode.

As described in detail above, the present invention stores the voice signal of the repetition section set by the user and repeatedly outputs the memory so that the user can repeatedly listen to the repetition section of the voice signal without waiting. You can listen correctly.
