Apparatus for reproducing 1 poly bell sound using MIDI audio source}

The present invention relates to a device for reproducing a single bell using a MIDI sound source, and more particularly to a device for reproducing a single bell using a MIDI sound source, which enables a user to reproduce a single sound bell having a minimum size.

The development of science and technology and the improvement of the economic level are accelerating the dissemination of mobile communication terminals and removing the restrictions of places for telephone calls. Currently commercially available mobile communication terminals are not limited to conventional telephone call functions, but include various functions such as text message transmission, photo shooting, and wireless Internet connection.

In addition, a user of the mobile communication terminal not only uses his or her mobile communication terminal to perform a specific function but also utilizes it as a tool for expressing personality by designating and changing a ringtone or a wallpaper.

The ringtone generally refers to a sound that is output when a call request is received from an originating terminal on a receiving terminal. The ringtones that can be played on a mobile terminal are one-tone ringtone, four-tone ringtone, and 16-tone ringtone. , Playable ringtone type is limited by the type of mobile communication terminal.

A single tone ring tone, which was used in the early stages of mobile communication terminal development, is a ring tone reproduced as a single tone beep sound using a buzzer and is called 1 poly. Poly is the number of sounds that can be played simultaneously, meaning that 1 poly can sound only one sound at a time. Since 1 poly ringtone data is small (about 70 bytes), it can be transmitted to a mobile communication terminal by text message (SMS).

However, due to the development of mobile communication technology and sound technology, multi-chord ringtones (ie, 4-chord ringtones, 16-chord ringtones, 40-chord ringtones, etc.) can be used as ringtones for mobile communication devices. The mobile communication terminal has a built-in sound source chip.

In addition, the mobile communication terminal describes the type of multi-chord ringtones that can be played on the outside, for example, in the form of 40 Poly, and the user downloads the multi-chord ringtones of the type described in the corresponding terminal through a communication network and selects the corresponding ringtone. As a result, it is possible to designate a ringtone when a telephone call request is received.

However, the conventional mobile communication terminal can only play the ringtone of a predetermined chord, there is a limit that can not be reproduced by modifying the ringtone in various types. Therefore, in the mobile communication terminal providing only a single tone ringtone, there is a problem in that the ringtone can be reproduced only by a single tone beep sound, and in order to reproduce a high quality ringtone, there is also a problem in that a new mobile terminal has to be newly purchased.

In addition, the user of the mobile communication terminal has to download and store the optimum ringtones that can be played in his mobile communication terminal, and thus there is a problem in that the type of the selectable ringtones is limited.

In addition, since the ringtone source data provided through the communication network is differentially charged according to the number of polys, there is a problem in that a user has to pay an expensive fee to receive a higher quality ringtone.

Accordingly, an object of the present invention is a monotone ring reproducing apparatus using a MIDI sound source to convert and reproduce the same sound source in various forms irrespective of the limitation of the playable sound source (for example, 1 Poly, 4Poly, etc.) in the mobile communication terminal. To provide.

Another object of the present invention is to provide a single-tone playback device using a MIDI sound source that can convert the single-tone ringtone data reproduced only in the form of a mechanical sound to various musical instrument sounds of refined sound.

Another object of the present invention is to provide a single-tone bell playback apparatus using a MIDI sound source that can be converted to a variety of ringtones, even if using low-cost sound source data, can minimize the cost of purchasing the data.

Another object of the present invention is that the user can freely select an instrument for converting the sound source data, so that even if a plurality of users use the same sound source data, the MIDI sound source can be differentiated for each user and express the individuality of the user. It is to provide a monotone playback device.

It can be set automatically and the instrument can be changed each time a call is received. In addition, when a 1 poly ringtone is to be designated as an incoming ringtone, the menu may be automatically reconfigured to only instruments that represent the correct pitch except for instruments that do not accurately represent a specific pitch.

Referring back to FIG. 2, in operation 240, the single-tone ring reproducing apparatus 100 determines whether a call is received from a calling terminal (not shown).

When the call is received, the single-tone ring reproducing apparatus 100 extracts, from step 345, the 1-poly type sound source data designated as the ring tone from the storage 120. In operation 250, MIDI format data of a predetermined type is generated using the sound source data of the 1 poly form.

The MIDI format data according to the present invention may be, for example, Synthetic Music Mobile Application Format (SMAF) data. Source data in 1 poly form is generally composed of a series of data values having a pitch and a length. The monotone playback apparatus converts these data values into data in the SMAF format consisting of a sequence of event and duration information. Of course, in this case, the instrument designation information, the volume information, and the balance information of the speaker may be included. The process of converting the 1 poly-type sound source data into the SMAF format data using the above-described information can be easily understood through the relationship between the SMAF format and the data values of the 1 poly sound data. do.

The monophonic reproducing apparatus 100 generates MIDI sound source data corresponding to the MIDI format data generated in operation 255 in operation 255, and proceeds to operation 260 to output the MIDI sound source data generated in operation 255 through the speaker. . The incoming ring tone output through the step 260 is not a single poly bell of the poly-type stored in the storage unit 120 but the sound of the musical instrument converted by the corresponding single bell.

Thereafter, the single-tone ring reproducing apparatus 100 determines whether the user has responded to the telephone call request from the calling terminal in step 265. If the incoming call is not made, the process proceeds to step 260 again. If the incoming call is made, the process proceeds to step 270 to end the playback of the MIDI sound source data and to make a phone call with the caller.

So far, the time for converting and outputting 1 poly-type sound source data into a performance sound of a specific instrument in the monophonic bell reproducing apparatus according to the present invention has been described with a focus on the case where a call is received from an arbitrary calling terminal. It is natural that the same operation may be performed in a specific instrument designation step by the user, a wake-up call time specified by the user, an alarm designation time specified by the user, a schedule notification time specified by the user, and a time point for receiving a short message. Of course, the sound source data of the 1 poly form designated as the game effect sound may be converted into an arbitrary instrument playing sound and output by the user's setting. However, even if the above-described respective cases are not described in detail, those skilled in the art will be easily understood through the above description, and thus redundant descriptions thereof will be omitted.

As described above, the single-tone ring playback apparatus using the MIDI sound source according to the present invention, for example, a variety of the same sound source irrespective of the limitation of the predetermined sound source (for example, 1 Poly, 4Poly, etc.) to be reproduced in the mobile communication terminal, etc. Can be converted to form and played back.

In addition, the present invention can convert the single-tone ringtone data, which is reproduced only in the form of machine sounds, into various musical instrument sounds with refined sounds.

In addition, the present invention can be converted to various types of ringtones and reproduced even if using low-cost sound source data, it is possible to minimize the cost of purchasing the sound source data.

In addition, the present invention allows the user to freely select an instrument for converting the sound source data, so that a plurality of users may be differentiated for each user and express the individuality of the user even when using the same sound source data.
