Abstract

A music file reproducing method using an ear microphone of a mobile terminal is provided to prevent an additional cost from incurring because of designing an additional button outside a mobile terminal and an increase in the size of the mobile terminal. It is checked whether a button of an ear microphone is inputted for longer than a certain time in an initial stage(301,303). When the button is inputted for longer than the pre-set time, a music file list is displayed(305). With the music file list displayed, button inputting is sensed(307). If the button is inputted once for a short time, a currently selected music file is reproduced(309,311). When the button is inputted twice for a short time, a next music file is selected(333,335). When the button is inputted for more than the pre-set time, the music file reproduction function is terminated(339,341).

How to play music file using ear microphone in mobile communication terminal {METHOD FOR PLAYING MUSIC FILE USING EAR-MICROPHONE IN MOBILE COMMUNICATION TERMINAL}

The present invention relates to a method for playing a music file in a mobile communication terminal, and more particularly, to a method for implementing a music on demand (MOD) function using an ear-microphone.

Mobile communication terminals are rapidly spreading due to the convenience of portability, and thus service providers (terminal manufacturers) are competitively developing terminals having more special functions to secure a large number of users.

On the other hand, the ear microphone (or "earphone") has a button for reducing the size, lightweight. When the user presses the button of the earphone, the terminal displays the recent call list on the display window and presses the button again in that state to attempt the call. This process will be described with reference to the drawings.

In step 105, the controller checks whether the button of the ear microphone is input again. When the button of the microphone is input again, the controller attempts to make a call to the last telephone number (last call number) in the list in step 107. In step 109, the controller checks whether a button of the ear microphone is input. When the button input of the ear microphone is detected, the controller proceeds to step 111 to stop the call attempt.

As described above, according to the related art, the terminal does not check whether the button of the ear microphone is short or long, and shows the recent call list when the first button is input, and the last time regardless of the input time when the second button is input. Try to call the phone number.

On the other hand, a terminal capable of playing music files, such as a VOD terminal, a music terminal, or an MP3 terminal, supports playback of music files only when the folder is open, or when the folder is closed, a separate 3-4 button is externally mechanically. By designing the MOD function by using the button, there is a problem in that the volume of the terminal is increased or a separate device design is required.

Therefore, there is a demand for a function of playing a music file even when a folder is closed without making a separate button outside the terminal.
