Abstract:
An electronics/heat sink housing for a powered speaker having a speaker enclosure with a rear panel, a front panel, a pair of side panels, and a pair of end panels, a passive radiator mounted to the rear panel for propagating sound pressure waves and air movement, and electronic components to allow the speaker to audibly emit sound, said electronics/heat sink housing comprising:a substantially planar back plate, a pair of oppositely-situated side plates and a top plate forming a cover of a size and shape to fit over the electronic components and passive radiator of the powered speaker, said cover being attached to the rear panel of the speaker enclosure over the electronic components and passive radiator; andsaid cover defining a plurality of slots communicating between an interior face thereof adjacent to the passive radiator and the exterior thereof and of a number such that the combined open area of the slots is greater than the surface area of the passive radiator in order to allow heat and air flow created by movement of the passive radiator to exit the slots outside the cover.
