Compact Speaker System with Controlled Directivity
6 May 21
A speaker system is disclosed with user-selectable output modes including controlled directivity output modes (e.g. selectable monopole, dipole, or cardioid radiation patterns), that may be implemented with adjustable electronic delay of out-of-phase driver elements, and that provides for both even-orderharmonic distortion reduction and driver force cancellation in a compact assembly suitable for home or studio use.

Utility
Line array speaker with frequency-dependent electrical tapering optimized for midrange and high frequency reproduction in the nearfield
3 Aug 20
A speaker system is provided having a line array of drivers wired in parallel and treated with passive or active component systems that serve to electrically taper its effective radiating length with frequency so that it is long/tall at low frequencies and short at higher frequencies, with the effective length of the array determined so as to maintain a listener in the nearfield at typical home and studio listening distances while minimizing the destructive effects of path-length dependent high frequency comb filtering.
