Patent ID: 7766122

Claim:
A sound generating and transmitting apparatus comprising: a radiator including inner and outer reflecting surfaces, the inner reflecting surface being formed on a cone reflector and the outer reflecting surface being a forward concave dish disposed around the cone reflector, the shaped reflecting surfaces defining sets of equivalent acoustic input locations in first and second focal rings of non-zero circumference; plurality of sound sources positioned in either a set of equivalent acoustic input locations for the first focal ring or a set of equivalent acoustic input locations for the second focal ring to provide a pair of distributed, functionally continuous sounds sources, one sound source being oriented to radiate sound inwardly against the cone reflector and a second sound source being oriented to radiate sound outwardly against the forward concave dish; the distributed, functionally continuous sound sources being arrays of discrete acoustic transducers arranged in closed loops; and coincident forward radiant axes for the inner and outer reflecting surfaces.
