A mobile device is provided to use a speaker module as a support board. A module settling unit(12) in which a speaker module(20) is settled is formed in a bottom part of a back side of a main body(10). An inclination unit(14) is inclined toward the center from both ends of the module setting unit. The inclination unit is formed in an inner surface of the bottom of the module settling unit. The inclination unit corresponds to a bottom shape of the speaker module. When the speaker module is settled in the module settling unit, the inclination unit minimizes a gap in the back side of the main body. The speaker module outputs sound. The speaker module is settled in the module settling unit. Each speaker module is rotatably hinge-coupled centering on both ends of the module settling unit. A hinge hole(21) passing through top and bottom of one side end of the speaker module is formed. A hinge shaft(23) is inserted into the hinge hole to be rotatable.
