Abstract: A speaker ball with housing with spherical outer surface, defines an interior volume. A button with a segment of the spherical surface is movable from a first position where the segment is held contiguous with the spherical surface, to a second inward position, that leaves a circular contact ring on which the speaker ball can rest without rolling. An audio driver is in the interior volume for generating sound and a toggle mechanism connected between the button and a remainder of the housing alternately holds the button in its first position and allows the button to move to its second position when the button is repeatedly pressed and released.
