Abstract
A loudspeaker battery charging device comprises a three-position selector that establishes one of a first, second, or third charging mode for charging a battery of a loudspeaker. The first charging mode pertains to an off state of the loudspeaker. The second charging mode pertains to an on state of the loudspeaker. The third charging mode pertains to a fast charge state of the loudspeaker. A controller receives a signal from the three-position power switch indicating a selected charging mode of the first, second, or third charging mode. A switch circuit outputs a first power-supplying level in response to the first or second charging mode and outputs a second power-supplying level higher than the first power-supplying level in response to the third charging mode.
