摘要： The speaker system of the invention comprises a pair of inner and outer rightward loudspeakers and a pair of inner and outer leftward loudspeakers all of which are arranged such that their points of sound transmission are aligned on an equal vertical straight plane in front of a listener and the inner speaker of each pair is horizontally inwardly spaced from the outer speaker of the same pair a distance which is equal to the distance between the respective ears of the human head to thereby form a parallel crosstalk cancellation planes extending perpendicular to the frontal plane on which the speakers are arranged. A first crosstalk cancellation network is connected between the input circuits of the outer rightward speaker and the inner leftward speaker and a second crosstalk cancellation network is connected between the inner rightward speaker and the outer leftward speaker. Right- and left-channel binaural signals are applied to the inner right and leftward speakers, respectively.

摘要： The present invention provides a method of manufacturing a lens array for recording or reproducing three-dimensional images with enhanced precision comprising uniform convex lenses of excellent optical properties without difficulties. A plurality of circular plateaus 3m having uniform diameter and shape are formed two-dimensionally arranged with high precision on a transparent substrate 3 by utilizing a laser plotter or an electron beam exposure system. A predetermined amount of transparent liquid resin 5 is dropped onto the respective circular plateaus one after another. The transparent liquid resin is left as it is until it forms dome shapes on the respective plateaus due to its surface tension. The dome shaped transparent liquid resin 5′ is hardened, so that the lens array having excellent and uniform optical properties two-dimensionally regularly arranged is obtained.

摘要： A stereophonic reproduction system comprises a localization network receptive of sterophonic signals to localize of sonic images at desired locations. A crosstalk canceler, connected in tandem with the localization network, cancels acoustic crosstalk interference. The localization network comprises in each channel a first adder providing algebraic summation of the input signal of the own channel and a negative feedback signal supplied from its output through a first subtractor and through a first transfer circuit having a transfer function representing the ratio of hypothetical crosstalk path transfer function to hypothetical direct path transfer function. The subtractor also responds to the signal of the other channel to algebraically combine the received signal in phase through the first transfer circuit with the input signal of the own channel. The crosstalk canceler comprises in each channel a second adder providing algebraic summation of the signal from the first adder and the signal of the same channel through a second subtractor and a second transfer circuit having a transfer function representing the ratio of actual crosstalk path transfer function to actual direct path transfer function. The second subtractor also responds to the signal from the second adder of the other channel to combine the received signal with the signal from the first adder in opposite phase through the second transfer circuit. Attenuators permit manual adjustment of signals supplied to the first and second subtractors of each channel.
