High fidelity sound reproduction system and modules thereof

In a high fidelity sound reproduction system, at least two modules each consisting of a relatively small loudspeaker and a speaker enclosure having a concavity therein with an essentially spherical shape, said concavity being truncated to define an enclosure opening, the speaker being mounted in said concavity with the periphery of its diaphragm essentially filling and closing said opening, said speakers being approximately of the same size and said enclosure concavities also being approximately of the same size, together with a number of baffle plates on which said modules are mounted with said enclosure openings substantially coincident with similar opening in the baffle plates, said loudspeakers being electrically interconnected for simultaneous reproduction of a common input signal, and said baffle plates together defining an essentially continuous surface surrounding said openings.

In a high fidelity sound reproduction system, a multiplicity of loudspeaker modules mounted on a number of baffles presenting to the listener an essentially continuous common surface,

• each said module comprising a single dynamic loudspeaker having a magnet at one end and a diaphragm at the other, and a single cavity-defining primary enclosure, said cavity being bounded by a smooth, substantially continuous curved surface, said cavity being truncated to define an opening in the enclosure, and said loudspeaker being supported on said enclosure with its magnet end extending into said cavity while its diaphragm end fills and closes said opening,
• said baffles containing spaced apart openings substantially identical with the enclosure openings, and receiving said modules with the two sets of openings in closing registry with one another and with the periphery of said loudspeaker diaphragm flush or closely adjacent said baffle surface,
• said loudspeakers being electrically interconnected for simultaneous reproduction of a common input signal.

An article of manufacture for a high fidelity sound reproduction system, said article comprising a single dynamic loudspeaker and a block-shaped cavity-defining primary enclosure having one face intersected by said cavity to define a single opening, the remaining area of said face defining a rigid baffle surface, the cavity in said enclosure except for said opening being defined by a smooth, substantially continuous curved surface,

• said loudspeaker having a longitudinal axis with inner and outer ends, a magnet structure at the inner end and a diaphragm at the outer end,
• said loudspeaker being disposed in the enclosure with its magnet and disposed in said cavity and its diaphragm end supported by the enclosure to fill and close said opening.

In a high fidelity sound reproduction system, the combination of

• A. a dynamic loudspeaker having a longitudinal axis with inner and outer ends, a magnet disposed at the inner end and a single membrane diaphragm at the outer end,
• B. a primary enclosure defining a substantially unvented concave cavity and having an opening to said cavity, said cavity being defined by a substantially continuous curved surface, and
• C. an outwardly convex secondary enclosure or baffle plate also having an opening therethrough of substantially the same size as the opening in said primary enclosure, said enclosures being secured together with said openings substantially coincident, said loudspeaker being disposed with its inner end extending cantilever style within said cavity and supported on said enclosures at its outer end with said diaphragm filling said openings and the outer periphery of the diaphragm approximately flush with the outer surface of the secondary enclosure.
