The ringtone download method of the present invention includes the steps of storing the sound transmitted by the user as an audio file, converting the audio file into a ringtone file, and downloading the converted ringtone file at the user's request to the mobile phone With steps.

Converting an audio file into a ringtone file includes converting the file into an ADPCM file, nibble swapping the ADPCM file, attaching a ringtone file header to the front, and a cyclic redundancy check (CRC) to the rear. Attaching a value may include.

In addition, the step of storing the sound transmitted by the user as an audio file may include sending a web page including a ringtone recording menu as the user connects through the Internet, and the user selects a ringtone recording menu and over the Internet. As the sound is transmitted, the method may include storing the sound as a file in an audio form.

In addition, the step of storing the sound transmitted by the user in the form of an audio file includes the step of sending an auto-response message to guide the ringtone recording in the automatic answering system as the user dials in and dials, and the user transmits the sound through the telephone As a result, the method may include storing the file as an audio file.

The storing of the sound transmitted by the user as an audio file may include exporting a message including a ringtone recording menu as the user connects through a wireless Internet network using a mobile phone, and the user selects a ringtone recording function. The method may further include connecting the user's mobile phone to the automatic answering system.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram showing a system and network configuration for constructing the method of the present invention.

The ringtone download system 100 of the present invention includes an audio file storage unit 140 for storing a file of an audio type recorded by a user, and an audio type file stored in the audio file storage unit 140 as a ringtone file. Ringtone converting unit 130 for converting, ringtone file storage unit 150 for storing the converted ringtone file, ringtone download unit 160 for downloading the ringtone file stored in the ringtone file storage unit 150 to the mobile phone ).

The audio file storage unit 140 may be a temporary memory such as RAM (Read Only Memory) for storing an audio file received from a user, or may be a hard disk memory.

The ringtone converting unit 130 converts an audio file stored in the audio file storage unit 140 into an ADPCM file, and then nibble swaps the file and attaches a ringtone file header to the front part. Attach the CRC (Cyclic Redundancy Check) value at the back to convert the ringtone file. The conversion method to the ringtone file will be described later.

The ringtone file storage unit 150 is for storing the converted ringtone file, and the ringtone file may be deleted immediately after downloading the ringtone to the user who recorded the ringtone or a person designated by the user, or the ringtone file may be continuously stored to store the ringtone. You can also make it freely available for recording or general users. In this case, it is desirable to store a list of files separately so that general users can easily find ringtone files.

2 shows a process in which a user records his voice and downloads it as a ringtone.

When the user connects to the ringtone download system 100 to record his or her voice or uploads a desired sound file, the voice or sound file is an audio file type (* .wav, * .rm, * .ra, * .asf, * .smp, * .voc, * .aif, * .snd, * .mp3, ...) are stored in the audio file storage 140 (S210). In this case, the audio file is preferably a wave (* .wav) or ADPCM (* .vox) file, but is not limited thereto.

Users may access the ringtone download system 100 through the general telephone network A using the general telephone 200. To this end, the ringtone download system 100 may be provided with an ARS (auto answering system) 110. When the user makes a call to the ARS 110, the ARS 110 sends a announcement so that the user can select a function of recording a sound to be used as a ringtone. The content recorded by the user is stored in the audio file storage 140 in the form of an audio file.

Users can also access the ringtone download system 100 via the Internet B using the computer 300. To this end, the ringtone download system 100 may include a web server 120. When the user accesses the web server 120 using a web browser, the web server 120 displays a web page including a menu for selecting a function for recording or uploading a sound that the user wants to use as a ringtone. To provide. You can record your own voice using the microphone, or you can have your own sound files (* .wav, * .rm, * .ra, * .asf, * .smp, * .voc, * .aif, You can also upload * .snd, * .mp3, ...) directly. The web server 120 stores the sound recorded by the user in the audio file storage 140 in the form of an audio file. In addition, the file uploaded by the user is converted into a file form of a form convenient for use in the ringtone file unit 130 as it is and stored in the audio file storage unit 140. For example, when using a Yamaha ma2 sound source chip, an ADPCM file is convenient, so it is preferable to convert the file to an ADPCM file (* .vox) and store it.

The users may access the ringtone download system 100 through the mobile communication network C through the base station 410 using the mobile phone 400. In this case, the case where the telephone is connected to the ringtone download system 100 is the same as the case of using a general telephone, so detailed description thereof will be omitted.

In addition to using the mobile phone 400, it is possible to access the ringtone download system 100 through the wireless Internet. That is, the web server 120 may be accessed through the internet network through the gateway 420 connected to the mobile communication network (C). When the user accesses the wireless Internet using the mobile phone 400, the web server 120 provides the user with a menu for selecting a function of recording a sound that the user wants to use as a ringtone. When the user selects this function, the web server 120 connects the user's mobile phone to the ARS 110 through the mobile communication network (C). Subsequently, the user's sound is recorded and stored in the audio file storage 140 by the same procedure as that connected to the ARS 110 using a general telephone.

The file stored in the audio file storage 140 is converted into a ringtone file (S220).

A process of converting a ringtone file when the yamaha ma2 sound source chip is used will be described in detail with reference to FIGS. 3 to 5.

FIG. 3 is a flowchart illustrating in detail a ringing file change step of FIG. 2. If the file stored in the audio file storage 140 is a wave (* .wav) file, it is converted into an ADPCM file (* .vox) (S310). If the file stored in the audio file storage 140 is an ADPCM file, step S310 can be omitted.

Next, nibble swapping is performed within bytes of the data of the ADPCM file (S320). That is, the upper 4 bits (= nibble) and the lower 4 bits in one byte are inverted.

In this way, a file header of a ringtone format is attached to the front of the nibble swapped data. The following is an example of the header of the Yamaha ma2 file format (* .mmf).

A cyclic redundancy check (CRC) value of all data is attached to the rear portion of the nibble swapped data.

The format of the ringtone file generated in this way is shown in FIG. That is, the ringtone file header 510 is attached to the front of the nibble swapped voice file 520, and the CRC region 530 is added to the rear part of the nibble swapped voice file 520 to form a ringtone file (S330).

The ringtone file generated as described above is downloaded to the user's mobile phone or the user's mobile phone designated by the user (S230). In addition to the user who recorded or uploaded the ringtone, the ringtone download system 100 may be connected to download the ringtone stored in the ringtone file storage 150. The ringtone download procedure stored in the ringtone file storage unit 150 is similar to the existing ringtone download procedure, and thus detailed description thereof will be omitted.

While the invention has been described using some preferred embodiments, these embodiments are illustrative and not restrictive. For example, the ringtone file conversion process has been described using the yamaha ma2 sound source chip as an example, but the present invention is not limited thereto. If you use a sound source chip that uses a different ringtone file format, you can convert it to match the format and store it in the ringtone file storage. Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the invention and the scope of the rights set forth in the appended claims.

As described above, according to the present invention, when the general users directly record their voices or upload their own sound files, they are automatically converted into the ringtones of the mobile phone and downloaded to the user. It is said to be effective.
