Abstract
A mobile terminal includes a portable terminal housing and a speaker housing positioned in the portable terminal housing. The speaker housing includes a first micro-speaker having a first frequency response and a second micro-speaker having a second frequency response and positioned proximate the first micro-speaker. The terminal housing further includes a first passageway extending from a front face of the first micro-speaker to a first opening in the terminal housing, and a second passageway extending from a back face of the second micro-speaker to a second opening in the terminal housing displaced from the first opening. A grommet adjacent the speaker housing acoustically separates at least a portion of the first passageway from the second passageway. The first passageway may be completely acoustically separated from the second passageway by the grommet and/or a gasket and/or a foam structure. The grommet may define a first outlet extending from a front face of the first micro-speaker to a first location on an external surface of the grommet and a second outlet extending from a back face of the second micro-speaker to a second location on the external surface of the grommet that is displaced from the first location, so that the grommet may acoustically separate the second outlet from the first outlet, although complete acoustic isolation may not be possible.
