Abstract:
1. A coaxial passive radiation monomer comprising: a passive radiator comprising a flexible surround mounting, an active radiator transducer assembly having an active audio loudspeaker driver components for converting electrical energy to sound waves, and an active radiator surround mounting for actively radiating sound waves, and a frame support member for encasing and housing said active audio loudspeaker driver components, and operatively supporting said passive radiator and wherein said passive radiator is located circumferentially about said active radiator transducer assembly; and an elastic membrane located circumferentially adjacent said frame support member and operatively connected to said frame support member for optimizing resonance frequencies for both the active radiator transducer and the passive radiator: and a support mechanism encasing and containing said active radiator transducer assembly, said active audio loudspeaker driver components, and said elastic membrane; and wherein the elastic membrane has a circumferential diameter that is approximately half the diameter of the frame support member; and wherein said support member encases and contains both said active radiator transducer and said passive radiator; and the mass of said passive radiator equals the same of the mass of the active radiator and the active radiator surround mounting.
