ABSTRACT:
Provided is a speaker device for a portable terminal. The speaker device includes a speaker housing which provides a mounting space for accommodating a speaker unit and a resonating space connected to the mounting space and located around the mounting space. The speaker device solves the disadvantages of a small-size speaker unit, i.e., problems in producing a sound in a bass region, thereby producing a “live” sound. Moreover, the characteristics of a sound can be improved using the speaker housing, without addition of a separate speaker unit or addition or change of software or a circuit, thereby improving the performance of a speaker device of the portable terminal at low cost.
