ABSTRACT:
This invention provides a lens system for a loudspeaker. The loudspeaker may include a driver unit and a waveguide attached to the driver unit. The loudspeaker further may include a lens system. The lens system may include a plurality of plates. The plates may be positioned to divide an interior of the waveguide into a plurality of acoustic paths of substantially equal length. The acoustic paths may bend the propagation of one or more acoustic elements of a sound wave so that each acoustic element arrives at a plane substantially at the same time.
