Abstract:
1. A speaker cabinet, comprising: a base cabinet which houses at least one speaker with at least one connection hole in one of the four sides and at least one connection hole in a side that is perpendicular to the one side, at least one female connector centered on the at least one connection hole in the one side and at least one female connector centered on the at least one connection hole in the side that is perpendicular to the one side, at least one male connector which passes through either the at least one connection hole in the one side or the at least one connection hole in the side that is perpendicular to the one side and attaches to the female connector of either the at least one connection hole in the one side or the at least one connection hole in the side that is perpendicular to the one side, whereby (a) a user of said speaker cabinet can secure a mating speaker cabinet in bearing to the first cabinet with said male connector and either female connector and thereby increase the number of speakers in a speaker array, and (b) said user can remove one or more speakers in the speaker array, an input jack having first and second connections; a speaker connection having first and second connections, the first connection of the speaker connection being connected to the first connection of the input jack; a series output switching jack having first, second, third, fourth, fifth, and sixth connections, the fourth connection of the series output switching jack being connected to the second connection of the speaker connection, the first connection of the series output switching jack being connected to the second connection of the input jack, the second connection of the series output switching jack being connected to the third connection of the series output switching jack, wherein when a plug is not inserted into the jack the first connection of the series output switching jack is connected to the third connection of the series output switching jack while the second connection of the series output switching jack is connected to the fourth connection of the series output switching jack, and wherein when a plug is inserted into the jack the first connection of the series output switching jack is no longer connected to the third connection of the series output switching and the second connection of the series output switching jack is no longer connected to the fourth connection of the series output switching act while the third connection of the series output switching jack is connected to the sixth connection of the series output switching jack and while the fourth connection of the series output switching jack is connected to the fifth connection of the series output switching jack; and a parallel output switching jack having first, second, third, fourth, fifth, and sixth connections, the first connection of the parallel output switching jack being connected to second connection of the input jack, the third connection of the parallel output switching jack being connected to the second connection of the series output switching jack and to the third connection of the series output switching jack, the fourth connection of the parallel output switching jack being connected to the second connection of the speaker connection, when a plug is not inserted into the jack the first connection of the series output switching jack is connected to the third connection of the series output switching jack while the second connection of the series output switching jack is connected to the fourth connection of the series output switching jack, and wherein when a plug is inserted into the jack the first connection of the parallel output switching jack is no longer connected to the third connection of the parallel output switching and the second connection of the parallel output switching jack is no longer connected to the fourth connection of the parallel output switching act while the third connection of the parallel output switching jack is connected to the sixth connection of the parallel output switching jack and while the fourth connection of the parallel output switching jack is connected to the fifth connection of the parallel output switching jack, wherein the plug being inserted into the series output switching jack places the speaker connection in series with series output switching jack relative to the input switching jack while breaking an electrical circuit between the fifth and sixth connections of the parallel output switching jack and the input jack and wherein the plug being inserted into the parallel output switching jack places the speaker connection in parallel with the parallel output switching jack relative to the input switching jack while breaking an electrical circuit between the fifth and sixth connections of the series output switching jack and the input jack.
