BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment in which the present invention is applied to a mobile phone device will be described below with reference to the drawings. FIG. 1 is a circuit block diagram of a mobile phone device according to the present invention.
[0012]
An antenna 1 is connected to a control circuit 3 via a radio unit 2. Then, the key input unit 4, the driver circuit 5, the driver circuit 7, the ROM (Read Only Memory) 9, the RAM (Random Access Memory) 10, and the external connection terminal 11 are connected to the CPU 3. Further, a speaker 6 is connected to the driver circuit 5, and a display device 8 is connected to the driver circuit 7.
[0013]
The control circuit 3 comprehensively controls the entire mobile phone device using the RAM 10 that stores control data in accordance with the program stored in the ROM 9. Hereinafter, only the function relating to audio data, which is a characteristic part of the present invention, will be described.
[0014]
The control circuit 3 connects to the Internet via the wireless unit 2, downloads compressed audio data, such as one that is published on a homepage on the Internet, and stores it in the RAM 10.
[0015]
This audio data has a data configuration as shown in FIG. As shown, the audio data is composed of a plurality of frames (packets), and each frame includes a header section 21 storing information such as a data format, and an information management section 22 storing bit allocation information and the like. , The data body 23 are included.
[0016]
FIG. 3 is a diagram showing the details of the header section 21. As illustrated, the header section 21 stores information such as an ID, a layer, a protection bit, a bit rate, and a sampling frequency. For example, in the case of MP3, since the ID is “1” and the layer is “01”, “1” is stored in the ID of the header section 21 and “01” is stored in the layer. Similarly, in the case of AAC, “1” is stored in the ID of the header section 21 and “00” is stored in the layer. Therefore, by detecting the ID and the layer of the header section 21, the data format of the audio data can be identified.
[0017]
The control circuit 3 converts the audio data into a data format that can be reproduced by the portable telephone device based on the audio data conversion program stored in the ROM 9 based on the information in the header section 21 and stores the data in the RAM 10. At this time, the data before the conversion may be deleted from the RAM 10 and only the data after the conversion may be stored in the RAM 10, or both the data before and after the conversion may be stored.
[0018]
Next, the operation of voice data conversion will be described. The control circuit 3 analyzes the header section 21 of the audio data to determine the data format. As described above, the data format of the audio data can be determined by the ID of the header section 21 and the layer.
[0019]
When the data format is determined, the control circuit 3 converts the header portion 21, management information portion 22, and data body 23 of the audio data to be converted into a data format that can be reproduced by the portable telephone device based on the program stored in the ROM 9. Then, it is stored in the RAM 10. For example, if the audio data to be converted is MP3 and the data format reproducible on the mobile phone device is AAC, the layer of the header section 21 is converted from “01” to “00”, and the data body 23 is converted to data corresponding to AAC. Convert to

Next, a procedure for connecting the converted audio data to generate audio data will be described with reference to the flowchart in FIG. The control circuit 3 drives the speaker 6 via the driver circuit 5 by the user's operation of the key input unit 4 to reproduce the audio data. At this time, the user listens to the reproduced audio data and cuts the audio in the range to be cut out. When the data is operated and instructed by operating the key input unit 4, the control circuit 3 stores the audio data in that range in the RAM 10 (step S1). At this time, the audio data to be cut is the data of the data body 23. The user repeats this operation until the voice data to be connected is completed (step S2). Then, data cut out from the RAM 10 by the user's operation of the key input unit 4 is read, and the read voice data is joined in the order of the user's instruction (step S3). Then, the connected voice data is used as the data body 23, and the header section 21 and the management information section 22 corresponding to the data body are stored in the connecting RAM 10 as new voice data (step S4).
[0021]
In the present embodiment, the audio data is connected to the Internet via the wireless unit 2, downloaded and stored in the RAM 10, but the external connection terminal 11 and an external device such as a personal computer are connected by a cable and stored. Alternatively, by making the RAM 10 detachable, the RAM 10 may be connected to an external device such as a personal computer, and audio data may be stored in the RAM 10 on the external device.
