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

As shown in FIG. 1, the mobile communication terminal according to an exemplary embodiment of the present invention includes a memory 11, an input unit 12, a speaker 14, a display unit 15, and a control unit 13.

The input unit 12 includes a plurality of key buttons (not shown) such as numeric keys, character keys, and menu selection keys, and when a user presses a key button, a signal corresponding to each key is generated and transmitted to the controller 13. . For example, the key input unit 12 may use a DTMF (Dual Tone Multi Frequency) method in which two frequencies correspond to one key button at the same time, one of four frequencies of the low frequency group and the high frequency group.

The display unit 15 is a device for displaying a corresponding number, letter, or menu screen as a user presses a key button of the input unit 12. For example, the display unit 15 may be provided as a liquid crystal display (LCD) with low power consumption. have.

The memory 11 stores a program necessary for driving the mobile communication terminal and temporary data generated during the execution of the program. In particular, the memory 11 stores at least one music file. The memory 11 in which the music file is stored is preferably provided as a nonvolatile memory in which the stored data does not disappear even when the power is cut off.

Here, the music file may be provided in various file formats having an extension of mid, mp3, asf, wma, and the like.

The control unit 13 sets any one of the music files stored in the memory 11 according to a user's selection, and whenever a key button signal of the input unit 12 selected by the user is detected, the melody included in the set music file. Each section of is output to the speaker 14 in order to hear.

That is, the control unit 13 first sets any one of a plurality of music files stored in the memory 11 to be heard according to a key button operation, and when the user presses a series of character buttons for writing a text message, for example. Each time the character button is pressed, the set music file is decoded (played) and outputted through the speaker 14.

In this case, the controller 13 may divide the melody of the music file into predetermined sections and output the respective sections of the melody to the speaker 14 in order each time a key button operation is detected by the user.

There are several ways to divide the melody of the music file into certain sections, one of which is to divide the melody waveform output to the speaker at a predetermined time interval, and the other is to divide the melody of each music included in the melody.

In addition, the controller 13 may control each sound included in the music file to be output to the speaker 14 while the user presses a key button. In this case, the music file should contain information about each pitch of the melody, for example, a MIDI file having a .mid extension.

MIDI is an abbreviation of Musical Instrument Digital Interface, which transfers performance information between musical instruments.It does not contain stream-like information, such as MP3 files or WMA files, but it contains information about the pitch, time, and size of the melody. It is a format configured to express the sound with various sound sources.

Since the MIDI file includes the information about the pitch as described above, the controller 13 may output a sound corresponding to the pitch to the speaker 14, for which the controller 13 outputs the corresponding sound. It may include various sound sources for. That is, different sound sources may be output to the speaker 14 even if the sound source is different for the same sound, and the selection of the sound source may be preset according to a user's key button manipulation.

As such, when the corresponding sound is output to the speaker 14 using the pitch information, the controller 13 may maintain the output of the sound for a time when the key button is pressed by the user. That is, the time at which each sound of the melody is output can be changed by adjusting the time when the user presses a key button. A detailed description thereof will be made in detail with reference to FIG. 5.

2 is a diagram showing the relationship between each module of the mobile communication terminal of the present invention.

As shown in the figure, the key button melody module 23 which performs the function of the control unit 13 exists between the operating system 22 and the Java virtual machine 24 of the mobile communication terminal, thereby providing a Java virtual machine. The melody output function according to the operation can also be used for a key button in various programs driven on (24), and preferably the present invention can be applied when writing a text message.

As such, when the melody output function according to the key button manipulation of the controller 13 of the present invention is implemented in a module form, the key button melody module 23 may be downloaded and installed through the wireless Internet.

Since the process of downloading each module executed in the mobile communication terminal through the wireless Internet is already known, a detailed description thereof will be omitted.

Hereinafter, a control flow of a mobile communication terminal according to an embodiment of the present invention will be described in detail with reference to FIG. 3. In the present exemplary embodiment, the melody of the music file is heard as the user presses the character button when the user writes a text message.

According to the user's selection, the control unit 13 sets a melody to be output, that is, a music file, according to the key button operation (step S1). In this case, the user may select any one of a plurality of music files stored in the storage unit by using a menu.

When the user selects a menu for creating a text message, the controller 13 displays the text message creation screen on the display unit 15 as shown in FIG. 4 (step S2).

At this time, the control unit 13 determines whether the set music file includes the music score information (step S3). This determination may be determined by checking the extension of the stored file, or may be determined by analyzing the file format in real time.

Here, the meaning of including the score information means a state configured to have information about the pitch and the beat of each note of the melody to be played and to play the music file using a predetermined sound source. For example, a file in MIDI format contains information on a particular key selected by the user (user pressed) on a synthesizer, etc., as well as information on the time the key is pressed and the speed at which it is pressed. Is the pitch, the time the key is pressed corresponds to the beat, and the speed at which the key is pressed corresponds to the sound strength. Since the sheet music can be generated using this information, it is referred to as the sheet music information in this embodiment.

When the music file contains the music score information, the control unit 13 loads (loads) the set file and prepares to play it (step S4), and checks whether a key button signal by the user is input (step S5). ). Loading of the file set here may be performed on volatile memory (not shown).

If the key button signal is input and the input key button signal is not the end button signal (step S6), the control unit 13 outputs a specific sound of the melody of the set music file while the key button signal is input ( Step S7). Thereafter, the controller 13 determines whether a key button signal is input in a state where the sound to be output is shifted and prepared (step S5). This process (steps S5 to S8) continues until the control section 13 detects the end button signal. The end button signal is, for example, a text message transmission signal, and when detecting this, the control unit 13 deletes the loaded configuration file and performs an initialization process. Accordingly, when a text message is again created after the end button signal, the processing for the set music file is restarted from the beginning.

As described above, the control unit 13 may include various types of sound sources in order to decode the MIDI file and output the same to the speaker.

The above is described in detail with reference to FIG. 5 as follows. In the same figure, a musical score with notes is shown, which can be derived using pitch information and time signature information extracted from a set file, and is shown for convenience of description, and in fact, a file in which data about the score itself is set. It does not need to be stored in.

The lyrics portion beginning with "Naviya" below the score is shown for ease of understanding, and the "key input" portion below the lyrics represents the letter button of the key button actually selected by the user.

In other words, if the user enters the text "hello", the first character "in" consists of the letters "o", "ㅏ", and "b", respectively, and the user presses a key button corresponding to each letter. Each time, the control unit 13 outputs each sound of the melody to the speaker 14 in order. In other words, when the user presses the first "o", the control unit 13 outputs the first note corresponding to the lyrics "I", and when the user presses the second "ㅏ", the control unit 13 corresponds to the lyrics "rain". If the user presses the third "b", the control unit 13 outputs a third sound corresponding to the lyrics "ya".

At this time, the control unit 13 may output a corresponding sound according to the beat of each sound, but in the present embodiment, while the user presses a key button, the control unit 13 continuously outputs the corresponding sound to the speaker 14. Accordingly, the speed of each sound output to the speaker 14 and the speed of the entire melody according to the speed at which the user writes a character may be changed.

As described above, in the present invention, since a specific sound is not fixedly assigned to each key button, different sounds may be output to the speaker 14 according to the progress of the melody even when the same key button is pressed.

On the other hand, referring to FIG. 3 again, if the control unit 13 determines that the music file information is not included in the set file (step S3), it loads (loads) the corresponding setting file (step S9). The process is divided at predetermined time intervals (step S10). Here, the division means not dividing the configuration file itself, but dividing the configuration file on the stream outputted to the speaker. This division process may be performed in real time before the decoded stream is output to the speaker.

The time interval for dividing may be preset by the user, and preferably set according to the speed at which the user writes a text message. In other words, if the speed at which the user composes a text message (the speed at which the key button is operated) is high, the time interval for dividing the melody is shortened. If the speed at which the text message is slow is set, the time interval for dividing the melody is set long.

6A illustrates an example in which melodies are divided at predetermined time intervals. The waveform in the figure represents an arbitrary melody waveform. That is, when the set file is a file format such as MP3, ASF, WMA, etc., if the corresponding file is decoded and the waveform before output to the speaker 14 is observed, the waveforms of FIG. 6A may be observed. Here, the horizontal axis time and the vertical axis mean amplitude.

As described above, when the waveforms are divided at predetermined time intervals, the waveforms may be divided into ① sections, ② sections, ③ sections, and ④ sections. It is assumed here that each section has the same time interval.

Upon receiving the first key button signal by the user in this state (step S11), the control unit 13 causes the ① section to be output to the speaker 14 (step S13), if it is not the end button signal (step S12). , Shifts the melody section to prepare to output the section ② to the speaker 14 (step S14).

Subsequently, upon receiving the second key button signal by the user (step S11), if the control unit 13 is not the end button signal (step S12), ② the section is output to the speaker 14 (step S13), while the melody The section is shifted to prepare for outputting the section ② to the speaker 14 (step S14).

In the same manner, section ③ and section ④ may be sequentially output to the speaker 14 according to a user's key button manipulation.

FIG. 6B is a diagram illustrating a case in which a speed at which a user presses a key button corresponds to a time interval in which a melody is distinguished correctly. As in the above example, a case in which the user inputs "hello" is described as an example.

When the user inputs "ㅇ", the control unit 13 outputs the first ① section of the melody to the speaker 14. Subsequently, when the user inputs "ㅏ" and "b" in order, the control unit 13 outputs the sections ② and ③ in order. In FIG. 6B, since the time when the user inputs the key button is exactly the same as the time when the melody is separated, the melody output to the speaker 14 may be naturally heard without being cut or overlapped.

On the contrary, FIG. 6C is a diagram illustrating a situation in which the time interval when the user presses a key button is earlier than the time interval at which the melody is divided. In this case, an effect of overlapping sounds occurs at the end of each melody section.

FIG. 6C is a diagram illustrating a situation in which a time interval when a user presses a key button is later than a time interval in which melodies are classified. In this case, after the end of each melody period becomes silent for a certain time, as if the melody is cut off in the middle.

In this state, when the melody interval is divided according to a predetermined time interval, the user can listen to the preset melody in various ways (overlapping, dropping effect, etc.) according to the key button input speed when composing a text message. You can have more fun.

On the other hand, the present invention is not limited to the above specific embodiments, but can be modified and modified in various ways without departing from the gist of the present invention. It will be apparent that such variations and modifications are included in the present invention as long as they belong to the appended claims.

As described above, according to the present invention, the user can hear the preset melodies being played in sequence every time the key button is pressed, and in particular, the user can feel as if he is playing a desired song while writing a text message.

Moreover, by pressing each key button, each section of the melody is output to the speaker so that you can create a text message and control the progress of the melody, thus giving the user various fun.
