Abstract:
A cone reflector/coupler speaker system having reduced diffraction loss, the system comprising:a speaker driver having an output surface; anda cone reflector, said cone reflector having a top, a base and first and second included angles, wherein said top is placed adjacent to said output surface of said speaker driver, wherein the first included angle extends from the top of the cone reflector to a transition point and is selected to reflect sound generated by said speaker driver within a plane approximately parallel to said base, wherein the second included angle extends downward from the transition point, and wherein the base is oriented to the speaker driver such that when the speaker system is placed on a coupling surface the coupling surface acts as an extension of the cone reflector, thereby reducing diffraction loss, wherein the transition point minimizes reflection of sound waves back into said speaker driver.
