When the digital sound source is reproduced, a vertical bar 203 indicating a point currently being reproduced is displayed on the spectrum in which the entire spectrum of the audio signal is displayed according to the reproduction time.

When the lyrics contents of the digital sound source are arbitrarily input to the lyrics contents input field 204 by the user, the input lyrics contents are displayed on the screen (S304). Here, it is preferable to input the lyrics content by one measure or one word.

When the time information add button 206 is selected by the user at the time when the position of the vertical bar 203 on the spectrum that is moved in accordance with the time when the digital sound source is played indicates the playback point or section corresponding to the lyrics input by the user, In addition, time information is added to the corresponding lyrics to be displayed on the screen (S305). Here, the added time information is to display the start point time or the segment time of the start and end point of the lyrics content.

As shown in FIG. 3B, in a state where all of the lyrics information input for the reproduced digital sound source is completed (S311), it is determined whether the user stores the digital sound source and the lyrics information as one file or as a separate file. In operation S312, when the user selects the save as one file button 207, the lyrics information is stored together in the digital sound source file (S313).

In the step of storing lyrics information together in the digital sound source file (S313), the digital sound source is recorded in an audio tag in which additional information such as artist information, a song title, an album title, and a publication year of the digital sound source file is recorded. The path of the presence data and the lyrics information indicating whether the file and the lyrics information are stored together is stored (S314).

In addition, when the user determines whether to store the digital sound source file and the lyrics information as a single file or as a separate file (S312), when the user stores the lyrics alone button 208 is selected, The sound source file and the lyrics information file are stored respectively (S315).

In step S315, respectively, storing the digital sound source file and the lyrics information file, storing the presence data and the path of the lyrics information file indicating whether the independent lyrics information file is stored in the audio tag in which the additional information of the digital sound source file is recorded. (S316), the independent lyrics information file is allocated and stored an additional space added to the digital sound source file (S317). In this case, the additional space added to the digital sound source file may be allocated additional information storage space to an audio tag of the digital sound source file or the main data storage space of the digital sound source file.

When the lyrics information editing of the digital sound source file is completed, the user connects the personal computer and the mobile communication terminal through the data cable for the mobile communication terminal, and the digital sound source file or the lyrics information including the lyrics information to be transmitted to the mobile communication terminal. When the file is selected separately stored in the digital sound source file, the personal computer transmits the file to the connected mobile communication terminal (S318). The data cable for the mobile communication terminal is, for example, a general data cable and a USB data cable, and is connected to the connection unit 20 of the mobile communication terminal.

When the file transfer is completed from the personal computer, the mobile communication terminal stores the file in the memory 18 and the multimedia card 19 (S319).

4 is a flowchart illustrating a process of reproducing a digital sound source file and lyrics information file according to the present invention, and FIG. 5 is an exemplary view showing a screen state in which the digital sound source file and lyrics information file are reproduced according to the present invention.

As shown in FIG. 4, when the digital sound source reproducing function is selected by the user of the mobile communication terminal (S401), the main control unit 30 is a digital unit stored in the memory unit 18 or the multimedia card 19. The sound source file is searched and the digital sound source file list is displayed on the display unit 16 (S402).

When the user selects a predetermined digital sound file and selects a play button on the digital sound file list (S403), the main control unit 30 reads the selected digital sound file into a buffer (not shown) in units of predetermined blocks. (S404), the read digital sound source file is decoded (S405).

The presence or absence of lyrics information files is determined by checking presence or absence data in the audio tag of the decoded digital sound source file (S406). When lyrics information is not present in the digital sound source file, the sound source data of the digital sound source file is converted into an audio signal. In addition, the playback time is counted and displayed on the display unit 16 (S407), and the audio signal is output to the speaker 13 or the earphone 14 through the codec 15 (S408).

In addition, when lyrics information exists in the digital sound source file, check the path of the lyrics information to determine whether the digital sound source file and the lyrics information are stored as a single file or as an independent file (S409). In the case of a digital sound source file having lyrics information stored in the digital sound source file, the digital sound source file and the lyrics information are separated (S410).

In step S409, when the lyrics information file is stored in the digital sound source file, when the lyrics information file is stored as an independent file, the lyrics information file is checked as a buffer by checking the path where the lyrics information file is stored. Read and store (S411).

The main control unit 30 converts the sound source data of the digital sound source file into an audio signal, counts the playing time, and displays the playback time on the display unit 16. The audio signal is output from the speaker 13 or the earphone (eg, through the codec 15). 14) (S412).

When the reproduction time of the reproduced audio signal matches the reproduction time information stored in the lyrics information file, the contents of the lyrics are read from the buffer (S413), and the lyrics are displayed on the display unit 16 (S414).

As shown in FIG. 5, the display unit 16 of the mobile communication terminal displays a spectrum of a digital sound source currently being reproduced at the top of the screen, and a playback time 501 counting the time at which the digital sound source is reproduced. And a plurality of function keys 504 for controlling the name and capacity 502 of the digital sound source file currently being played, the lyrics contents 503 displayed at a time coinciding with the playback time of the digital sound source, and the digital sound source currently being played. ) Is displayed.

As described above, the present invention stores the digital sound source playing time information and the lyrics information file having the lyrics content stored in the digital sound source file downloaded to the mobile communication terminal or stored in the multimedia card. Lyrics that match to are read from the lyrics file and displayed on the screen.
