| 20090176534 | MOBILE TERMINAL HAVING FLAT PANEL SOUND OUTPUT UNIT AND VIBRATION GENERATION METHOD FOR THE SAME - A mobile terminal having a flat panel sound output unit and vibration generation method for the same are disclosed. When a user touches the mobile terminal, the user can feel a sense of touch through the flat panel sound output unit. The mobile terminal includes: a touch screen; a flat panel sound output unit attached on a surface of the touch screen to generate sounds or vibrations according to an input signal; and a vibration processor sending, when a touch event occurs at the touch screen, a signal to the flat panel sound output unit to generate vibrations corresponding to the touch event. Hence, the method can provide a sense of touch to the user without use of a separate vibration motor. | 07-09-2009 |
