Here, the camera 50, the signal processor 60, and the image processor 70 provided for capturing the person or the surrounding environment may not be an essential component in the present invention. However, it may be an essential component when a key input for selecting a camera mode is provided independently.

Looking at the operation of processing the key sound of the portable terminal as described above, First, the operation process of the portable terminal for the key sound setting through the key sound setting menu as follows.

In the key tone setting menu, the controller 10 executes a program corresponding to the key tone setting menu stored in the memory 29 to display screen data according to the key tone setting menu on the display unit 80. Thereafter, the controller 10 recognizes the key sound set through the keypad 27, stores the set key sound information in the memory 29, and then ends the key sound set menu. When the key sound is set, the key sound selected through the key sound setting menu is basically provided by the portable terminal, that is, in the rain mode, the raindrop key sound is registered in the memory 29, and the female voice mode is the female voice key. Sound setting information is registered in the memory 29. In addition, if the user production mode in which the user can directly produce a key tone sound by the key tone sound control the user to write the key tone sound through the keypad 27, the text of the key tone sound is stored in the memory 29 and , The key sound is set. In addition, in the music mode, it is possible to set a music file such as MP3 as a key sound.

Subsequently, the controller 10 recognizes the key input through the key data generated by the key input through the keypad 27 and displays the number and letter displayed by the key on the display unit 80 and displays the data of the key sound sound set through the above process. The audio processor 25 is output. Then, the audio processor 25 processes the data of the input key sound and outputs the key sound to the speaker SPK.

In order to provide a key tone corresponding to a key input through the portable terminal, a key tone must be set.

2 is a flowchart illustrating a key sound setting method of a portable terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in step 211, the controller 10 determines whether a key sound tone is set. The key tone setting menu may be entered by selecting a key tone setting menu among menus supported by the portable terminal after a key tone setting key or a menu key input.

As a result of the determination, in step 213, the controller 10 displays the key sound setting menu on the display 80. That is, the key tone setting menu screen as shown in FIG. 3 is displayed on the display unit 80.

Thus, the key tone mode that can be set through the key tone setting menu is as follows. First, the normal mode that is basically provided in the portable terminal, that is, raindrop key sound, ping pong key sound, female voice key sound, child voice key sound, robot voice key sound as shown in FIG.

Second, a user production mode in which a user directly creates and registers a desired key tone sound, that is, a user can directly register a key tone sound by converting a character of the produced text into a voice as shown in FIG. 4. There is a text-to-speech conversion mode to provide so that, as shown in Figure 5 there is a music mode that allows the user to directly register the desired keytone sound as music.

Then, in step 215, the controller 10 detects a key sound mode selected from the key sound modes.

As a result of the detection, in the normal mode, in step 217, the controller 10 registers one of the basically provided key sounds in the memory 29 as key sounds. That is, one of the raindrop, ping pong, female voice, child voice, and robot voice of FIG. 3 is registered.

However, as a result of the detection, in step 219 in the user production mode, the control unit 10 detects whether the text-to-speech conversion mode is performed. Registers the text created through the key sound. That is, as shown in FIG. 4, texts can be created by using a key tone up to the numeric keys “0 to 9”, special keys “*” and “#”. In addition, the confirmation key, the end key, and even the navigation key (direction key) can be used to compose text with a key sound. Here, in the case of a portable terminal having a camera 50, the text may be written with a key sound even for a shortcut key for entering the camera mode. At this time, the user can hear the key sound for the written text in advance. Text written through the text-to-speech conversion mode is output as a robot voice, a female voice, a child voice, etc. according to a user's selection.

In the text-to-speech conversion mode, as described above, text may be registered as a key sound and at the same time, a background sound may be registered according to a user's selection. In this case, the background sound may be a ringtone, melody, or MP3 music.

In contrast, if the music mode is determined in operation 219, the controller 10 displays a music registration screen on the display unit 80 so that the music file can be registered with a key sound corresponding to the key in operation 223. Then, in step 225, the controller 10 registers the music file selected through the keypad 27 as a key sound. In this case, the user may listen to the music registered in advance as the key sound. That is, as shown in FIG. 5, music keys may be registered with a key tone up to the numeric keys "0-9", the special keys "*", and "#". Also, the confirmation key, the end key, and even the navigation key (direction key) can be used to register the music by the sound of the key sound. Here, in the case of a portable terminal having a camera 50, it is possible to register music with a key sound even for a shortcut key of the camera mode. At this time, the user may listen to the music registered as the key sound in advance. Herein, the music should be stored in the memory 29, and the user can arbitrarily edit the music playing time of the key sound.

After the above steps 217 to 223, in step 225, the controller 10 determines whether the confirmation key is input, and when the confirmation key is input, the control unit 10 proceeds to step 227 and sets the key sound sound registered through the above-described process as the key sound sound.

However, if the confirmation key is not input, in step 229, the controller 10 maintains the previously set key sound.

In addition, the key tone sound setting method of the present invention is a key tone sound of the portable terminal, even if the setting state of the key tone sound to the character voice conversion mode in the state that previously set the MP3 music through the music mode as the key tone sound in the music mode The registered MP3 music file information is not deleted. Therefore, the previously registered MP3 music or text is retained as it is, and simply converts the key tone setting mode from the music mode to the text-to-speech mode or the text-to-speech mode to the music mode, and uses previously registered text or MP3 music as the key tones. This is possible.

6 is a flowchart illustrating a key sound control method of a portable terminal according to an embodiment of the present invention.

Referring to FIG. 6, in step 611, the controller 10 determines whether a key input has occurred, and when the key input occurs, the controller 10 proceeds to step 613 to recognize a key input key.

In operation 615, the controller 10 detects a set key sound mode.

As a result of the detection, if the set key tone mode is the normal mode, in step 617, the controller 10 outputs the set key tone among the key tone sounds basically provided in the portable terminal.

However, as a result of the detection, if the set key tone mode is the user production mode, in step 619, the controller 10 determines whether the text to speech mode.

As a result of the determination, in the text-to-speech conversion mode, in step 621, the control unit 10 reads the voice data, which is voice-converted by the set text of the corresponding key input key, from the memory 29, and processes the read voice data to output the key sound. do. In this case, the key sound sound corresponding to the set text of the key input from the memory 29 may not be read, and the text sound may be converted into a voice sound and then output as a key sound sound in real time. For example, as shown in FIG. 4, when the text "thank you" is set as the key sound of the number key "1", the letter "thank you" is converted into a voice and output as a key sound.

In addition, when there is music registered as a background sound together with the text in the key sound sound registration process of the text-to-speech conversion mode of FIG. 2, the background sound registered by the user is output while performing the above-described step 621.

On the other hand, if it is determined that the character voice conversion mode is not performed in step 619, the controller 10 detects the music mode in step 623, reads the set music file of the corresponding key input from the memory 29, and reads the read music file. Play and output the key sound. For example, when "country country" is set to the number key "1" as shown in FIG. 5, when the number key "1" is input, the country song is output as a key sound.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described in detail above, the present invention enables the user to set different key tones desired by predetermined keys, thereby enabling the user to use the portable terminal with his / her desired key tones.

In addition, by converting the text written by the user into a key sound, or by providing music such as MP3 as a key sound, there is an effect of providing the user with his own unique key sound.

In addition, another object of the present invention has the effect that can be simple communication with the key sound set through the text.
