Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block circuit diagram showing a configuration of an audio reproducing apparatus according to one embodiment of the present invention.
In the audio reproducing apparatus according to the present embodiment, a recording medium 1 in which audio information is compressed (encoded) and recorded in a predetermined format as a digital signal is detachable, and the recorded audio is recorded with the recording medium 1 attached. It is a device that reproduces information. The recording medium 1 on which the audio data is recorded includes:
A recording medium capable of digitally recording audio data, such as a flash memory, a magneto-optical disk, or a magnetic disk, can be applied.

The audio data recorded on the recording medium 1 mounted as shown in FIG. The audio data that has been subjected to predetermined processing by the system control unit 2 is subjected to decompression conversion (combination) in a predetermined format in a digital signal processing unit (DSP) 3 which is a component of the information reproducing means, and D / A It is input to a converter (D / A) 4.

The audio data is converted into an analog audio signal by a D / A converter 4, amplifies the audio signal, and is input to a power amplifier (AMP) 5 that drives a speaker 6. The audio signal amplified by the power amplifier 5 is emitted from a speaker 6.

The audio data recorded on the recording medium 1 is recorded in a managed data area of the memory of the recording medium 1 on a file-by-file basis. It is assumed that the information is recorded on sequential addresses in the data area as the time elapses.
Therefore, the elapsed time of the reproduction of the audio data corresponds to the address value of the data area.

The system control section 2 is composed of a microprocessor and controls each element of the audio reproducing apparatus.
Further, it has control means for controlling the reproduction of the designated repetition reproduction section, storage means for storing the start or end position of the repetition reproduction section, and information reproduction means for reproducing the audio information.

The digital signal processing unit 3 is connected to the system control unit 2, and an operation input unit 7 for instructing an operation mode and the like of the audio reproducing apparatus is provided. And the like, which is connected via a drive circuit 9.

The operation input unit 7 is composed of a group of a plurality of operation switches that are turned on and off, which will be described later. According to each operation, the data of the recording medium 1 is controlled under the control of the system control unit 2. The reading is controlled, and the recording medium 1
Is read out and supplied to the digital signal processing unit 3. In addition, the system control unit 2
Is connected to a power supply control unit 10 for supplying a voltage to each circuit, and the power supply control unit 10 is controlled by the system control unit 2.

The operation input section 7 includes a PLA for a reproduction operation.
Y switch 7a, STOP switch 7b for stop operation
And F-SKIP switches 7c and R for selecting a file and for changing the reproduction position of the file.

And a RESET switch 7f for reset operation.

Here, the functions of the selection F-SKIP switch 7c, the selection R-SKIP switch 7d, the marking MARK switch 7e, and the reset RESET switch 7f will be described in detail. The MARK switch 7e functions as a start position designating unit and an end position designating unit in the repetitive reproduction. When the MARK switch 7e is operated after the reproduction mode is set, the address at that time is changed to the start position of the repetitive reproduction section. When the MARK switch 7e is operated again, the address at that time is stored in the system control unit 2 as the end position of the repetitive playback section. Then, the MARK switch 7e
Is operated, the operation mode is switched to the repetitive reproduction of the above section.

Further, the F-SKIP switch 7c, the RS
The KIP switch 7d is a switch normally used to select a file to be reproduced. However, when the operation mode is set to the repetitive reproduction, a repetitive reproduction start position or an end position for continuously changing the repetition reproduction section. Also functions as a position change designating means for changing. That is, each time the F-SKIP switch 7c is operated once when the operation mode is repeated reproduction, an appropriate time equivalent, for example, 1 second equivalent is added to the start and end addresses of the repeated reproduction section. Similarly, the R-SKIP switch 7
Every time d is operated once, a predetermined time equivalent, for example, 1 second equivalent, is subtracted from the address at the beginning and end of the repeated playback section.

Therefore, the F-SKIP switch 7c,
Alternatively, by operating the R-SKIP switch 7d, the same value is added to or subtracted from the address giving the position on the file giving the start and end of the repeated playback section, and the length of the section from the start to the end of the playback section Can be changed by continuously shifting the position of the playback section on the file without changing. RES
When the ET switch 7f is operated, the operation mode of the repetitive reproduction is released.

Next, the main processing operation of the audio reproducing apparatus according to the present embodiment having such a configuration will be described in detail with reference to FIG. FIG. 2 is a basic flowchart showing the processing operation of the audio reproduction device according to the first embodiment.

After the completion of the initial setting, each circuit is put into a waiting state until one of the operation switches in the operation switch group of the sound reproducing apparatus is operated (step S2). When it is detected that any of the switches has been operated, first, the operation state of the selecting F-SKIP switch 7c is detected (step S3). When the F-SKIP switch 7c is operated, the system control unit 2
Is added to the currently selected file number among the audio information files recorded in the file, and the file with that file number is set as the selected file (step S4). Thereafter, the process returns to step S2.

After detecting the operation state of the F-SKIP switch 7c in step S3, the on / off state of the selection R-SKIP switch 7d is detected (step S3).
5). If the R-SKIP switch 7d is operated,
The system control unit 2 subtracts 1 from the currently selected file number among the audio information files recorded on the recording medium 1, and sets the file of the file number as the selected file (step S6). Then, the above step S2
Return to

After detecting the operation state of the R-SKIP switch 7d in step S5, the state of the reproduction PLAY switch 7a is detected (step S7). When the PLAY switch 7a is operated, the system control unit 2 reads the data of the selected file recorded from the recording medium 1, sends the data to the digital signal processing unit 3, performs decompression processing, and performs reproduction processing ( Step S8). The details of the reproduction process will be described later. S for stopping during the above-mentioned reproduction process
When the TOP switch 7b is operated, the reproduction process is stopped, and the process returns to step S2.

The PLAY switch 7a in step S7
After detecting the operation state of the RESET switch 7
The state of f is detected (step S9). When the RESET switch 7f is operated, the address indicating the position of the repetitive playback section is initialized (step S10), and the process returns to step S2. If it is detected in step S9 that the RESET switch 7f has not been operated, it is regarded as an operation error, and the process returns to step S2.

Next, the details of the reproduction processing in step S8 will be described with reference to the flowchart of the reproduction processing of the subroutine shown in FIG. As described above, the playback P
When the LAY switch 7a is operated, the operation shifts to the reproduction process.
