| Abstract: |
A stereophonic sound reproducing system having left and right audio transducer means arranged relatively close to each other, and a combiner means connected to a stereophonic sound signal source for generating left and right signals R and L and combining the left and right signals R and L to produce a combined left sound signal L-γR and a combined right sound signal R-γL (γ representing a complex number coefficient). These combined sound signals L-γR and L-γR are fed to the left and right sound transducer means, thereby stereophonic sound is reproduced.

First Claim:
Show all 2 claims |
I claim as my invention:
1. A stereophonic sound reproducing system comprising first and second audio transducer means disposed in a common housing and fixed a distance d o = .lambda.o /2 sin θ apart from each other, where .lambda.o represents the wavelength of a component of the sound produced by said transducers, which wavelength substantially corresponds to the effective distance between the audio sensitive parts of both ears of listeners, and θ represents one-half of the angle between maximum sound pressure directions of difference sound components of right and left sounds produced by said first and second audio transducer means and which have said wavelength .lambda.o, a stereophonic sound signal source for generating right and left sound signals R and L, a combiner means for combining said right and left signals R and L to produce a combined right sound signal R- γL and a combined left sound signal L- γR, γ being a complex number coefficient, a first circuit means for feeding said combined right sound signal to said first audio transducer means and a second circuit means for feeding said combined left sound signal to said second audio transducer means.
