Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. However, it is obvious to those having ordinary knowledge in the art that various modifications other than those described below are possible without departing from the technical scope of the present invention.

FIG. 1 is a block diagram showing a configuration of a wireless communication terminal to which the present invention is applied.

The control unit 10 is implemented by a one-chip microprocessor and controls the overall operation of the wireless communication terminal. The key input unit 40 includes a number of numeric / alphabetic keys, a function key (FCN), a storage key (STO), and a volume up / down key, and generates key data corresponding to each key. The first memory 20 temporarily stores a predetermined operation program and data generated during execution of the operation program. The first memory 20 also stores scale display data, interval data, and note data corresponding to the key data for the present invention. The scale display data is data for displaying a scale name corresponding to each alphabetic key to indicate to the user a sound corresponding to the alphabetical key of the key input unit 40. The pitch data is data for specifying a pitch of a scale of two octaves, and the note data is data of a sound duration. The frequency of a signal generated by the following frequency generator 60 depends on the pitch data. The second memory 25
Stores the melody code and melody identification number. The display unit 30 displays data input from the key input unit 40 and various information such as an operation state. The RF unit 50
It performs amplification, filtering, and modulation / demodulation of signals transmitted and received by an antenna (ANT). The frequency generator 60
The frequency is generated under the control of the control unit 10. This frequency is transmitted by a buzzer as an alarm sound and a melody.

FIG. 2 is a flowchart showing an example of a control procedure of the melody input method according to the present invention.

When the power is turned on and the wireless communication terminal is set to the standby state, the control unit 10 proceeds to step 20.
In step 1, it is detected whether a melody input mode key is input from the key input unit 40. When the melody input mode key is input, in step 203, the communication terminal is set to the melody input mode. Then, step 205
Then, the scale display data of the key input unit 40 is read from the first memory 20 and the scale data of two octaves is displayed on the display unit 30.
Is displayed over two frames. Here, the user can change the frame using the volume down / up key.

When the scale is displayed on the display unit 30 in step 205, it is detected in step 207 whether a key input is performed from the key input unit 40. The key data input at this time are "pitch key data" corresponding to alphabetic keys and "note key data" corresponding to numeric keys. When key data is input in step 207, step 209 is executed.
Then, the scale display data displayed on the display unit 30 is deleted, and the input pitch key data and note key data are displayed on the display unit 30. Then, in step 211, the pitch data and the note data corresponding to the input key are read to generate a melody code. A melody chord for one note is composed of one piece of pitch data and one piece of note data.

When the melody code is generated in step 211, the flow advances to step 213 to detect whether a storage key is input from the key input unit 40. When the storage key is input in step 213, the process proceeds to step 227, where the melody code is stored in the second memory 25. If the storage key has not been input, the process proceeds to step 215, and it is detected whether the melody test key has been input from the key input unit 40. The melody test key is input by combining a function key with a numeric key / alphabetic key.

When the melody test key is input in step 215, the frequency generator 60 is controlled according to the melody code stored in the second memory 25 in step 217. At this time, the frequency generator 60 generates a frequency corresponding to the melody code under the control of the controller 10, and the generated frequency is converted into a sound by a buzzer and output as a melody. Thereafter, the process proceeds to step 219 to detect whether a storage key is input from the key input unit 40. When the storage key is input, in step 221,
The melody identification number is requested to be input through the display unit 30, and it is detected in step 223 whether the melody identification number is input. When the melody identification number is entered,
Proceeding to step 225, it is determined whether the same melody identification number as the inputted melody identification number is set in the second memory. If there is a melody identification number identical to the inputted melody identification number, step 2
Returning to step 21, the melody identification number is again requested to be input.

FIGS. 3A and 3B are diagrams showing specific examples of the scales input as described above. FIG. 4 shows keys corresponding to respective data constituting the code and addresses of these data signals.

FIG. 3A shows “Sommi-fa
3A. Each note has a pitch and a note. When each note in the score of FIG. 3A is represented by a combination of a pitch and a note (numerical number), “So2 So4 Mi8 Fa16 Pause note” 4 to 4 16. To input this to the communication terminal, the key input unit 40 uses “H02H0”.
4F08 G16 X04 I04 F02 K16 ".

When inputting as described above, the user inputs "
When the “H” key is input from the key input unit 40 to set “H”, the control unit 10 receives “H” key data from the key input unit 40 and displays “H” on the display unit 30, and FIG. As shown in (1), an eighth address signal corresponding to "H" is generated, and the pitch data at the eighth address of the first memory 20 is read. When the user inputs key data “02” indicating a musical note after inputting the “H” key, the control unit 10 receives the key data and displays it on the display unit 30. And the second
An 8-address signal is generated, and the note data at the 28th address of the first memory 20 is read out and combined with the pitch data of "G" to generate one melody code corresponding to the "G" sound of the half note. . Thereafter, the control unit 10 stores the generated melody code in the second memory 25. The user inputs one blank and then sequentially inputs the next pitch data in order to distinguish it from the next input pitch data.

The melody input in this manner is output in the same control procedure as the conventional melody output at the time of receiving a call.

[0021]

As described above, according to the present invention, a user can freely input a desired melody and can realize easy operability. As a result, differentiation from other communication terminals can be achieved, and the commercial value can be improved.
