The present invention relates to a playing device and a method of a portable wireless terminal, and more particularly, to a portable wireless terminal having a string musical instrument playing function and a method of playing the same.

The portable wireless terminal has been rapidly spreading due to the convenience of portable, and thus service providers (terminal manufacturers) are competitively developing terminals having more special functions to secure a large number of users.

For example, a portable terminal has a function of transmitting a specific sound (eg, human voice, dog sound, etc.) for a predetermined time instead of DTMF (Dual Tone Multi Frequency) each time a button on the keypad is pressed. This feature may initially be of interest to the user, but the user may easily get tired because the same sound is transmitted for a predetermined time.

In recent years, the performance of melody chips (e.g. Yamaha melody chips) installed in portable wireless terminals has developed at an alarming rate, and now it is possible to reproduce near-original sounds. In response to this trend, a music playing function using a keypad has recently been provided. However, since the keypad basically has only on / off states, it can only play simple music and does not satisfy the user's desire to play more complicated music (eg, stringed music). If you additionally use the touch screen, another input device, more complex music performance will be possible.

Accordingly, an object of the present invention is to provide a playing device and method using a touch screen and a keypad in a portable wireless terminal.

It is another object of the present invention to provide an apparatus and method for playing stringed music in a portable wireless terminal.

According to an aspect of the present invention for achieving the above object, the portable device for playing a wireless terminal, in the string instrument playing mode, the touch screen for displaying the strings of the selected string instrument, the user to generate the information of the string touched by the control unit And each button is mapped to a string or a code, and obtains a keypad generating code information of a button pressed by the user to the controller, and sound source data according to an input combination of the touch screen and the keypad. And a melody chip for converting the sound source data into a melody chip and converting the sound source data from the controller into an audible analog signal and outputting the sound source data to a speaker.

According to another aspect of the present invention, a method of playing a portable wireless terminal in which each button of the keypad is mapped to a string or a chord comprises: displaying the strings of the selected string instrument on a touch screen in the string playing mode; Acquiring sound source data according to a combination of code information input through the current information input through the touch screen and a database, and reproducing the sound source data through a melody chip and outputting the same through a speaker. It features.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, the present invention will be described a method for playing the present instrument music using the touch screen and the keypad in a portable wireless terminal. The string instrument may include a guitar, a violin, a cello, a gayageum, a lyre, and the following description will be given by way of example.

1 is a block diagram of a portable wireless terminal according to an embodiment of the present invention. In the following description, the portable radio terminal includes a cellular phone, a personal communication system (PCS), a personal data assistant (PDA), an international mobile communication-2000 (IMT2000) terminal, and 4G ( It is meant to include all OFDM (orthogonal frequency division multiplexing) terminals and the like, and the following description will be given with the general configuration of the above examples.

Referring to FIG. 1, first, the controller 100 controls the overall operation of the terminal. For example, it performs processing and control for voice calls and data communications, and processes functions for playing stringed music according to the present invention in addition to the usual functions. In the following description, description of the processing and control of the conventional control unit 100 is omitted.

The memory includes a program memory 102, a data memory 104, a nonvolatile memory 106, and the like. The program memory 102 stores a program for controlling the overall operation of the terminal. The program memory may use a flash memory. The data memory 104 temporarily stores data generated during the operation of the terminal. The data memory may use random access memory (RAM). The nonvolatile memory 106 stores system parameters and other storage data (telephone number, SMS message, image data, etc.). The nonvolatile memory may use an EEPROM. According to the present invention, the memory stores the sound source data of each string for each of a plurality of codes for each stringed instrument in a database.

Key pad 108 includes numeric keys 0-9, menu key, cancel key (clear), confirm key, call key (TALK), end key (END), Internet access key, navigation keys. A plurality of function keys such as (up / down / left / right) are provided, and key input data corresponding to a key pressed by the user is provided to the controller 100.

The touch screen 102 includes a liquid crystal display (LCD) and a touch panel installed on the liquid crystal display. The touch screen 102 displays state information, various moving images and still images generated during the operation of the portable terminal. In addition, it analyzes the electrical analog signal according to the screen contact, and outputs the position data and the pressure strength (strength) data according to the position of the touch screen to the controller 100.

Here, there are two ways to detect the pressure pressed by the user. First, in the case of a touch screen implemented through a pressure sensor, the pressure sensor is distributed in a lattice form. When the terminal user presses the screen hard, the number of pressure sensors responding to the screen increases. On the other hand, when pressed lightly, the number of pressure sensors responding thereto is reduced. That is, the pressure intensity can be calculated using the number of pressure sensors that react. Second, the screen itself can be implemented in the form of a button. A sensor is installed to detect the pressure below the screen, and the screen itself is a button. When the user presses the touch screen, the touch screen itself is pressed and the sensor senses the pressure applied at this time.

An audio codec (Coder-Decoder) 112 connected to the controller 100, a speaker 116 and a microphone 114 connected to the codec 112 are voice input / output blocks used for a voice call. The codec 112 converts the PCM data provided from the controller 100 into an analog voice signal and transmits the same through the speaker 116 and converts the voice signal received through the microphone 114 into PCM data. Provided to the controller 100.

The RF module 120 lowers the radio frequency (RF) signal received through the antenna 118 to the baseband processor 122 and provides the baseband processor 122 with a baseband from the baseband processor 122. The signal is raised in frequency and transmitted through the antenna. The baseband processor 122 processes a baseband signal transmitted and received between the RF module 120 and the controller 100. For example, in the case of using the CDMA communication method, a function of channel coding and spreading data to be transmitted and despreading and channel decoding the received signal is performed. Perform.

The melody chip 124 converts the music data (sound source data) of a predetermined format into an analog signal that can be heard by a human being and outputs it to the speaker 116. The melody chip 124 stores a variety of music data (melody), and when a specific event occurs (for example, when receiving a call signal) converts the corresponding audio data and outputs the audio signal to the speaker 116. According to the present invention, the melody chip 124 converts the sound source data according to the input combination of the keypad and the touch screen into an audible analog signal and outputs it to the speaker 116. For example, the melody chip 124 may use a Yamaha melody chip.

Looking at the operation of the present invention based on the configuration of Figure 1 as follows.

In the case of guitars, the most popular of the stringed instruments, the player produces the chord by pressing the strings of the guitar with one hand and plays the music by striking the strings of the guitar with the other hand. In addition to guitars, most stringed instruments, such as violins and gayageum, have a similar playing style to guitars. The present invention performs a code generation operation using a keypad input and a string bending (or turning on) operation using a touch screen input. That is, the present invention is characterized in that the string instrument performance is achieved by using the input combination of the touch screen and the keypad similar to the actual playing manner.

The touchscreen displays the strings that match the instrument you have selected. For example, the guitar displays six strings as shown in FIG. 3. In this case, the strings may be displayed horizontally or vertically according to a user's selection. The user presses or rubs the strings displayed on the touch screen with a finger or a stylus pen. Adjust the sound according to the pressure you press. As described above, since the present invention enables a complex input, the present invention can achieve the same effect as playing an actual stringed instrument.

2 illustrates a procedure for playing stringed music in a portable wireless terminal according to an embodiment of the present invention.

Referring to FIG. 2, first, in step 201, the controller 100 determines whether a playing mode is performed by a user's key manipulation. If the performance of the playing mode is not detected, the controller 100 proceeds to step 217 to perform a corresponding mode (eg, a standby mode). If the performance of the playing mode is detected, the controller 100 proceeds to step 203 and displays the string instrument selection request on the touch screen 110. For example, display such as '1: Other 2: Gayageum 3: Violin 4: Cello'.

In operation 205, the controller 100 determines whether a specific string instrument is selected by a user's manipulation. When the selection of the specific string instrument is detected, the controller 100 proceeds to step 207 to display the strings of the selected string instrument on the touch screen 110. For example, if guitar is selected, six strings are displayed vertically or horizontally as shown in FIG.

After displaying the strings of the selected string instrument, the controller 100 checks whether there is a touch screen input in step 209. When the touch screen input is detected, the controller 100 proceeds to step 211 to analyze the keypad input and the touch screen input. As described above, a user enters a code through a keypad and a sound through a touch screen.

For example, each button of the keypad may be mapped to one string. When the user presses a button on the keypad, the effect is the same as when the string mapped to that button is pressed. Thus, the user enters at least one button (s) to generate code. The mapping of buttons to strings can be changed by the user. As another example, you can map code to each button. In this case, the user can generate the desired code with a single button press. As another example, the first and second methods can be used in combination. In other cases, strings can be mapped to each of buttons 1 to 6 and code can be mapped to the remaining buttons.

Once the playing is started, the controller 100 checks the chord by the keypad input and interprets the sound input through the touch screen based on the checked chord. That is, the sound source data of each string should be stored in advance for each of the plurality of chords for each stringed instrument.

In this way, the sound source data according to the input combination of the touch screen and the keypad is acquired, and the controller 100 proceeds to step 213 to reproduce the obtained sound source data as an audible analog signal through the melody chip 124. Output through the speaker 116.

In operation 215, the controller 100 determines whether the playing mode is terminated by a user's manipulation. If the playing mode is not finished, the controller 100 returns to step 209 to perform the following steps again. If the playing mode ends, the controller 100 ends the algorithm of the present invention. Meanwhile, the music played as described above may be stored and edited in a memory and used as a ringtone.

In the foregoing detailed description of the present invention, specific embodiments have been described. However, various modifications may be made 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 determined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, the present invention provides a performance function using a combination of a keypad and a touch screen, and thus, there is an advantage in that more complex performance is possible and more realistic performance can be supported. That is, there is an advantage of enhancing the entertainment function of the terminal.
