Abstract
An input/output hall structure for a sound device in a portable terminal includes a main hole and a plurality of sub-holes. The main hole is provided in a case frame forming the exterior of the portable terminal to be exposed to the exterior, and inputs/outputs sound. The plurality of sub-holes is branched from the main hole and communicates with the main hole. The sub-hole and a corresponding sound device communicate sound. The structure reduces the number of holes for inputting/outputting sound of a sound device and provides a more elegant appearance with improved function. A plurality of sound devices can input/output through the main hole and branched configuration of sub-holes.
