Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an audio reproducing apparatus.

[0002]

2. Description of the Related Art In order for a sound reproducing device to have a function of outputting sound effects and voice guidance, a storage device for storing those sounds and a reproducing device for reproducing the sound stored in the storage device are provided. Is required. For example, a voice synthesis IC is built in a device, sound effect data and the like are stored in a ROM area in the IC, and a sound effect is emitted from the voice synthesis IC as needed. However, in this case, in addition to a reproducing device for reproducing data read from a medium, a reproducing device for reproducing a sound effect or the like is required, resulting in a problem that the cost is increased.

[0003]

SUMMARY OF THE INVENTION The present invention provides an audio reproducing apparatus which can reproduce sound other than media such as sound effects, and does not require a dedicated reproducing apparatus for reproducing sound other than media. The purpose is to do.

[0004]

According to the present invention, there is provided an audio reproducing apparatus comprising: a decompressing means for reading compressed audio data from a medium for decompression; and a reproducing means for reproducing the decompressed audio data. Audio data storage means for storing compressed audio data; and means for reproducing audio data stored in the audio data storage means, wherein the compressed audio data stored in the audio data storage means is provided. Has the same data format as the compressed data recorded on the medium, and the means for reproducing the audio data stored in the audio data storage means is used when reproducing the audio data stored in the audio data storage means. Decompressing audio data stored in an audio data storage means using a decompression means for decompressing media data And it features.

[0005] The voice data stored in the voice data storage means is, for example, voice guidance.

[0006]

FIG. 1 shows the configuration of an MD (mini-disc) player.

This MD player has a function of reproducing the MD disk 1, a function of reproducing the CD disk 8, and a function of reproducing the CD disk 8.
A function of dubbing audio data from the disk 8 to the MD disk 1 is provided.

The operation at the time of reproducing the MD disc 1 will be described. The audio signal read from the MD disc 1 is
The signal is processed by the signal processing unit 2 and temporarily stored in the memory 3. Thereafter, the data is decoded by the ATRAC processing unit 5 and D /
After the digital-to-analog conversion is performed by the A converter 6, the signal is output from the speaker 7.

The operation during reproduction of the CD 8 will be described. The audio signal read from the CD disk 8 is
The signal is processed by the signal processing unit 9 and temporarily stored in the memory 10. Thereafter, the data is decoded by the ATRAC processing unit 5, and
After being DA converted by the / A converter 6, the signal is output from the speaker 7.

When dubbing audio data from the CD disk 8 to the MD disk 1, the audio signal read from the CD disk 8 is processed by the signal processing unit 9 and temporarily stored in the memory 10. Thereafter, the data is decoded by the ATRAC processing unit 5, sent to the signal processing unit 2, processed, and recorded on the MD disc 1.

The control microcomputer 4 controls the entire system. The ROM (microcomputer ROM) in the control microcomputer 4 stores audio data compressed by the ATRAC method. The sound data stored in the microcomputer ROM includes a beep sound for confirming a key operation, a sound guidance, a sound indicating that the device is turned on, a sound effect (for example, a clapping sound), and the like.

When reproducing the audio data stored in the microcomputer ROM, the audio data is transferred to the memory 3, passed through the signal processing unit 2, decoded by the ATRAC processing unit 5, and output from the speaker 7. .

FIG. 2 shows a pre-procedure for dubbing audio data from the CD disk 8 to the MD disk 1. In this preprocessing, audio guidance audio data stored in the microcomputer ROM is reproduced and output.

When the dubbing key is pressed (step 1), it is determined whether or not a CD is loaded (step 2). If no CD is loaded, the process proceeds to step 7. If a CD is loaded, a voice guidance such as "Is this CD OK?" Is output (step 3). When the YES key is pressed (step 4), the process proceeds to step 8. If the NO key is pressed (step 5), the CD is ejected (discharged) (step 6), and the process proceeds to step 7.

Step 7 waits until a CD is loaded. When the CD is loaded, the process proceeds to step S8. In step 8, it is determined whether or not the MD is mounted.) Step 13 if MD is not mounted
Proceed to. If the MD is mounted, voice guidance such as "Is this MD OK?" Is output (step 9). When the YES key is pressed (step 1
0), and proceed to step 14. If the NO key is pressed (step 11), the MD is ejected (discharged) (step 12), and the process proceeds to step 13.

In step 13, the process waits until the MD is mounted. When the MD is mounted, step 14 is executed.
Proceed to. In step 14, "Start dubbing.
Are you sure? ”Is output. When the YES key is pressed (step 16), dubbing is started (step 17). If the NO key has been pressed (step 15), the process returns to step 1.

In the above embodiment, the case where the present invention is applied to an MD player has been described.
The present invention can be applied to audio reproducing devices other than the D player.

[0018]

According to the present invention, it is possible to obtain a sound reproducing apparatus which can reproduce sound other than media such as sound effects and does not require a dedicated reproducing apparatus for reproducing sound other than media.
