Abstract
The system of the present invention includes, briefly, a point source speaker system, comprising a processor which produces a left minus right (L−R) audio signal, a right plus left (R+L) and a right minus left (R−L) audio signal; three speakers each for audibly transmitting one of the L−R, R+L and R−L audio signals; and a point source speaker enclosure for housing the three speakers in a single enclosure.
Claims12
A speaker system for outputting at least an L-channel signal and an R-channel signal, comprising:
- a left speaker outputting a signal in which the R-channel signal is subtracted from the L-channel signal, wherein frequencies in the R-channel signal in the signal output by the left speaker are filtered out above a high frequency cut-off;
- a right speaker outputting a signal in which the L-channel signal is subtracted from the R-channel signal, and wherein frequencies in the L-channel signal in the signal output by the right speaker are filtered out above the high frequency cut-off;
- a center speaker outputting an un-multiplied signal in which the R-channel signal is added to the L-channel signal and frequencies in the L-channel signal and the R-channel signal are filtered out above the high frequency cut-off, and wherein the high frequency cut-off is dependent upon the size of the center speaker, right speaker and left speaker and proximity of the center speaker, right speaker and left speaker to a common point of origin;
- and
- an enclosure equipped with the left speaker, the right speaker, and the center speaker.

A speaker system for outputting L-channel signals and R-channel signals comprising:
- a center speaker;
- means for applying at least an un-multiplied center signal to the center speaker, wherein the center signal is comprising the L-channel signal added to the R-channel signal where frequencies of the L-channel signal and R-channel signal are filtered out above a high frequency cut-off;
- a left speaker;
- means for applying at least portions of the R-channel signal subtracted from the L-channel signal to the left speaker, wherein frequencies in the R-channel signal applied to the left speaker are filtered out above the high frequency cut-off;
- a right speaker;
- means for applying at least portions of the L-channel signal subtracted from the R-channel signal to the right speaker, and wherein frequencies in the L-channel signal applied to the right speaker are filtered out above the high frequency cut-off, and wherein the high frequency cut-off is dependent upon the size of the center speaker, right speaker and left speaker and proximity of the center speaker, right speaker and left speaker to a common point of origin;
- and
- an enclosure equipped with the left speaker, the right speaker, and the center speaker.
5 more elements
A speaker system for producing sound based upon left (L) and right (R) audio signals, comprising:
- a left speaker outputting an L−R speaker signal comprising the L audio signal minus the R audio signal, wherein frequencies of the R audio signal in the L−R speaker signal are below a pre-determined maximum frequency;
- a center speaker outputting an un-multiplied R+L speaker signal comprising the R audio signal plus the L audio signal in which frequencies of the R audio signal and the L audio signal are below the pre-determined maximum frequency;
- a right speaker outputting an R−L speaker signal comprising the R audio signal minus the L audio signal, and wherein frequencies of the L audio signal in the R−L speaker signal are below the pre-determined maximum frequency, and wherein the pre-determined maximum frequency is dependent upon the size of the center speaker, right speaker and left speaker and proximity of the center speaker, right speaker and left speaker to a common point of origin;
- and
- an enclosure equipped with the left speaker, the right speaker, and the center speaker.
