Abstract:
A remote surround sound speaker system comprising:a transmitter for transmitting wireless signals to a plurality of receivers, said wireless signals are capable of driving at least a front-left speaker, a front right-speaker, a center speaker, a rear-left speaker and a rear-right speaker, wherein said transmitter is capable transmitting sound signals including a left channel and right channel, said sound signals being first processed by a surround sound processor generating an in-phase sound signal consisting of a front-left sound signal and a front-right sound signal, and an out-of-phase sound signal consisting of a rear-left sound signal and a rear-right sound signal, said in-phase sound signal and said out-of-phase sound signal communicating with an in-phase transmitter and an out-of-phase transmitter, respectively, and wherein said in-phase transmitter and said out-of-phase transmitter each consist of FM transmitters used to transmit an in-phase broadcast signal and an out-of-phase broadcast signal respectively; a plurality of said receivers, each said receiver in wireless communication with said transmitter, each said receiver is capable of both remote and local signal level conditioning wherein graphic equalization, balance adjustment, fader adjustment, and volume adjustment are applied to the signal broadcast by said transmitter; a graphic equalizer capable of adjustment of the tonal characteristics of the sound, on several bands, by use of individual sliding knobs including a balance knob allowing for the adjustment of the sound between the right and left channels, a fader knob allowing for the adjustment of the sound between front and rear channels, a volume knob allowing for the adjustment of the playing volume, a conditioning selection switch allowing a user to select the location of the signal conditioning for one particular receiver, and a channel selection knob allowing for individual channel selection on a per speaker basis; a plurality of speakers, one said speaker in direct communication with one said receiver; and wherein said individual receivers are identical in construction and can be configured to communicate with said transmitter to drive at least a front-left speaker, a front right-speaker, a center speaker, a rear-left speaker or a rear-right speaker; wherein said in-phase sound signal and said out-of-phase sound signal are also fed, in parallel, to signal level conditioning circuitry, where said in-phase sound signal and said out-of-phase sound signal are further conditioned in terms of tonal characteristics of the sound, adjustment of the sound between the right and left channels, adjustment of the sound between front and rear channels and playing volume as defined by the user on the transmitter control panel via the graphic equalizer, balance knob, fader knob and volume knob, respectively.
