A lens system (210) for a loudspeaker. The loudspeaker may include a driver unit (202) and a waveguide (206) attached to the driver unit (202). The loudspeaker further may include a lens system (210). The lens system (210) may include a plurality of plates (302, 304, 306, 308, 310, 312, 314, 316, 318, 320, 322). The plates may be positioned to divide an interior of the waveguide (206) into a plurality of acoustic paths (332, 334, 336, 338, 340, 342) of substantially equal length. The acoustic paths may bend the propagation of one or more acoustic elements (324, 326, 328, 330) of a sound wave so that each acoustic element arrives at a plane substantially at the same time. |
