Abstract
A portable terminal includes: a body case including a button operation unit and a circuit unit; at least one sliding case which is sildably connected to the body case to protrude from the body case and in which a closed resonance space is formed when the sliding case protrudes; and at least one speaker which is installed in the sliding case and is placed in the resonance space when the sliding case protrudes. Accordingly, since the resonance space is formed in the sliding case, the quality of sound provided from the speakers to a user is enhanced.
