Abstract

A mobile terminal includes a speaker arrangement for providing surround sound. The terminal includes a folder hinged at a main body and having an LCD attached thereto, speakers mounted at the folder and implementing a three-dimensional surround-sound effect, and a sliding unit for sliding at least one of the speakers when the speakers produce the three-dimensional surround-sound effect. Because the distance between the speakers can be widened according to a user's selection, three-dimensional surround-sound can be maximized and thus product quality can be significantly enhanced.
