Patent ID: 8369561

Claim:
An information handling system, comprising: at least one speaker apparatus including an outer speaker cavity and an inner speaker box movably received therein, the inner speaker box having an internal cavity continuous in volume with the outer speaker cavity to form a total combined speaker box volume, the inner speaker box being adjustable between a first position retracted within the outer speaker cavity and a second position extended from the outer speaker cavity such that the total combined speaker box volume when the inner speaker box is extended from the outer speaker cavity is greater than the total combined speaker box volume when the inner speaker box is retracted within the outer speaker cavity; and at least one speaker driver positioned in the inner speaker box, the speaker driver being oriented such that movement of the inner speaker box within the outer speaker cavity from the first retracted position to the second extended position is in a sideways direction relative to the speaker driver; where the internal cavity of the inner speaker box has an internal volume space, and where the outer speaker cavity has an internal volume space, the inner speaker box being configured to be retracted within the internal volume space of the outer speaker cavity when the inner speaker box is in the first position retracted within the outer speaker cavity; and where the internal volume space of the outer speaker cavity is configured to be open to and continuous with the internal volume space of the inner box when the inner speaker box is extended from the outer speaker cavity to form a combined extended speaker box that includes at least a portion of the internal volume space of the outer speaker cavity combined with at least a portion of the internal volume space of the internal cavity of the inner speaker box such that the total combined speaker box volume made available to the speaker driver when the inner speaker box is extended from the outer speaker cavity is greater than the total combined speaker box volume made available to the speaker driver when the inner speaker box is retracted within the outer speaker cavity.
