Description

Communication device capable of reproducing into calling sound specific part of audio file and method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device for sounding a ring tone so that a user can recognize a call, and a ring tone sounding method thereof, and more particularly, to a communication device capable of reproducing a specific portion of an audio file as a ring tone and a ring tone reproducing method thereof.

Recently, as portable communication devices such as cellular phones and PDAs have been widely spread, people making calls using portable communication devices can be commonly seen in places where a large number of people gather. At this time, it is common to see that the ringing tone sounds before each call is different for each communication device, which indicates that the ringing tone is used as a tool for expressing the individuality of the user beyond the recognition means. In addition, the appearance of various ringtones as described above has been possible because the portable communication device that is recently released, because it supports to express a variety of telephone ringing. That is, recently released communication devices are basically designed so that various kinds of ringing sounds can be selectively reproduced by the user in the memory device built in the device so as to express various ringing tones. The new audio file can be downloaded, stored and played back, allowing users to vary the device's ringtone.

1 is a flowchart illustrating a method for reproducing a ring tone of a conventional communication device. First, when a call signal is transmitted from the outside (S110), the mobile communication device reads a preselected audio file among a plurality of audio files stored in the storage device (S120). Then, playback is performed from the beginning of the read audio file (S130). Subsequently, when the call signal is disconnected by the user or received from the external device is stopped (S140), the reproduction of the audio file is stopped (S150).

In the case of the conventional communication device as described above, when a call signal is transmitted from the outside, the pre-selected audio file is designed to be reproduced from the beginning of the file, and the user can recognize the call through the pre-selected call sound.

However, the conventional communication device has a problem that the call sound is not always used as the call sound in the audio file because the call sound is always designed to be played from the beginning of the audio file. That is, in general, the receiver selects a call connection immediately when a ring tone sounds, and most of the telephone lines are used only, and the desired portion is not used as the ring tone.

On the other hand, there is no way for the user to use his or her desired playback range in the audio file as a ringtone, but in order to use a specific portion of the audio file as the ringtone, the user can play the desired audio file from the original audio file using a separate audio editing program. By creating a new file with a range and selecting the newly created audio file as the ring tone, the desired ring tone could be expressed.

2 is a flowchart illustrating a method for reproducing a specific portion of an audio file as a ring tone in a conventional communication device. First, while the audio file is being played back (S210), when a play start position and a play end position desired to be used as a call sound are selected from the user, and the play range of the audio file is set (S220), a new form formed only of the audio data of the set play range Create a file (S230). At this time, the file name is different from the original audio file. For example, if the original audio file has the name 'bell 1', the new file formed only with the data of the reproduction range is named 'bell 2'. Then, when the user selects the 'bell 2' file from the call tone list as the call sound (S240), when the call signal is transmitted from the outside, the device repeatedly plays the 'bell 2' audio file from the beginning to the end (S250).

In the conventional communication device as described above, in order for a user to use a desired playback range in an audio file as a ring tone, a new file having a desired playback range must be generated from the original audio file. It will repeat playback until the end.

However, as described above, the user needs to edit the audio file through a separate program in order to obtain a desired ringing sound, which creates a new file, which takes up unnecessary storage capacity and is very troublesome.

In addition, a method of inserting desired playback position information into an audio file to play a specific part of the audio file has been used. However, since the original audio file is modified, the audio file can no longer be used for other purposes. Will have

An object of the present invention is to create a file through a separate editing program for the user's desired playback range in the audio file to solve the above problems or to use a specific portion of the file as a ringtone without modifying the original audio file And a method for reproducing the call sound.

The display unit 330 displays a setting tool for setting a reproduction range for the operation of the device and the audio file to be selected and reproduced, and also displays a list of audio files used as the call sound.

The storage unit 340 stores the file path information of each audio file, and the play range information is added to the file path information of the audio file according to the user's setting. The reproduction range information is composed of 2 bytes, with the upper 1 byte recording the start position and the lower 1 byte recording the end position. In addition, file path information and reproduction range information are distinguished using a special identifier.

The audio output unit 350 outputs a ring tone according to the reproduction of the audio file selected as the ring tone.

The controller 360 controls the overall communication device. In particular, when a play range is set for an audio file for use as a ring tone through the input unit 310, the controller 360 stores the file path information in the storage unit 340. Play range information is added to the file path information of the audio file and stored, and when a call signal is transmitted through the transmitter / receiver 320 in a state in which the audio file having the play range information is set as a call tone, the play is added to the file path information. Based on the range information, a specific section of the audio file is controlled to be repeatedly played.

An operation of the communication device shown in FIG. 3 will be described in more detail with reference to FIGS. 4 to 6.

FIG. 4 is a flowchart illustrating a process of setting play range information of an audio file in the communication device shown in FIG. 3. When a play command is selectively input from among audio files stored in advance through the input unit 310 (S410), the controller 360 plays the selected audio file (S420). Thereafter, when the user selects a playback start position and a playback end position to set an audio file playing range (S430), the playing range information set in the file path information of the selected audio file is added and stored in the storage unit 340 (S440). ). 7 is a diagram illustrating a storage form of file path information. As shown in FIG. 7, the file path information of the audio files is divided and stored by file identifiers, respectively, and the file path information and information of the audio file in which the play range information is set as in the first file path (file path 1). The identifier and play range information of the audio file are included. Here, the information identifier is used to distinguish the file path information and the reproduction range information of the audio file from each other. In addition, the reproduction range information is composed of two bytes, the upper one byte records the reproduction start position information, and the lower one byte records the reproduction end position information. 8 is a diagram illustrating in more detail a form in which file path information of an audio file is stored. The file path information indicating that the file 'GeneralBell1.wav' is in the 'windows' folder is recorded, and the information identifier (id) and the play range information (info) are added. In addition, the 'GeneralBell2.wav' file is divided by the 'GeneralBell1.wav' file and the file identifier (F id), and only the file information that is in the 'windows' folder is recorded. This shows that the 'GeneralBell1.wav' file has a play range but the 'GeneralBell2.wav' file does not have a play range.

FIG. 5 is a flowchart illustrating a process of designating a ring tone by a user in the communication device of FIG. 3. When a list display command for files that can be used as a ring tone is input from the user through the input unit 310 (S510), the controller 360 displays a list of audio files that can be used as the ring tone on the display unit 330. 9 is a diagram showing an example of a display form of a display unit for audio files that can be used as a ring tone. In FIG. 9, when a user selects a radio button corresponding to a bell in the 'bell / melody type' box and selects the audio file list display command button 710 of a selection box, a list of audio files that can be used as a ringing tone is shown. As shown below. At this time, only the file name is displayed in the list of files, and the reproduction range information of the file is not displayed. In FIG. 9, two files 'GeneralBell1.wav' and 'GeneralBell2.wav' are displayed. When the user selects a file to be used as the call tone from the above file list (S530), the controller 360 stores the selected file as a file for using as the call tone (S540).

6 is a flowchart illustrating a method for reproducing a ringing tone according to a device call from the outside. When a call signal to the device is transmitted from the outside through the transmitter / receiver 320 (S610), the controller 360 determines whether the file designated as the call sound is a file whose reproduction range is set, and stores file path information stored in the storage unit 340. Determine through (S620). At this time, if the play range information is included in the file path information, the control unit 360 repeatedly plays the specific section of the audio file designated as the call tone according to the play range information included in the file path information (S630). That is, when the file 'GeneralBell1.wav' is selected in FIG. 9, since the file 'GeneralBell1.wav' includes the file play range information in FIG. 8, the control unit 360 controls the play range information included in the file path information. As a result, the specified section of the file 'GeneralBell1.wav' is repeatedly played. If the file path information does not include the play range information, the file is repeatedly played from the beginning to the end of the selected audio file (S640). That is, if the 'GeneralBell2.wav' file is selected, since the 'GeneralBell2.wav' file in Figure 8 does not include the play range information of the file, the control unit 360 of the 'GeneralBell2.wav' file selected as a ring tone Play from start to end repeatedly.

On the other hand, the controller 360 stops playback of the call sound when a call is connected by the user while the call sound is being reproduced or a call signal transmitted from the outside is no longer detected.

According to the method for reproducing a call sound of a communication device and a communication device according to the present invention, a user can use a specific portion of an audio file as a call sound without creating a new file or modifying an original audio file using a separate audio editing program. While avoiding the hassle of creating an audio file or modifying an audio file, it is possible to increase the satisfaction of users who have a desire to express their personality in a single ring tone.
