摘要 An apparatus and method for providing sound in a mobile communication device using a sound output device capable of projecting sound in more than one direction such that a the user can recognize all the sound projected by the sound output unit and in a manner capable of enhancing low frequency sound reproduction. A plurality of air ducts connected to sound emitting ports are provided such that the sound projected in a plurality of directions by a speaker is emitted through the same surface of the device.
