Speaker System

摘要

An audio speaker comprises three modules stacked on one another to form a tower. The bottom module generates a magneto-strictive output that is coupled to the structure on which the bottom module stands to cause audio signal radiation from that structure. The top module has an upwardly facing cone speaker that radiates audio signals primarily in the upper audio frequency range. These two audio signal radiations combine to provide a more comprehensive frequency range signal than is normally obtained at the small size of the tower. An intermediate module plays media such as an audio card. The modules are releasably held together by embedded magnets in the adjacent facing surfaces of the modules. Signal information is transmitted between modules by terminals on adjacent facing surfaces. The upwardly facing surface has a set of recessed spring loaded upwardly extending terminals. The mating terminals on the downwardly facing surface are flush with the surface contact terminals.
