ABSTRACT OF THE DISCLOSURE A remote broadcast vehicle does not require any setup time, may remain fully enclosed and locked while in operation, and which prevents the ingress of moisture and other weather. The vehicle may includes a player for pre-recorded audio programs, a radio broadcast station receiver, wireless microphone and wireless remote control, mixer, cross-over, amplifiers and speaker assemblies. The system may further be used to up-link a program to a base radio station, and provide full programming capability. Additionally, a tuned port speaker system is disclosed for broadcasting low frequencies through the vehicle wall. Several different vehicle embodiments are illustrated.
An electrical audio processing system for processing a plurality of electrical source signals and converting said plurality of electrical source signals into an audio broadcast, said electrical audio processing system transported by a vehicle having an interior compartment surrounded by a vehicle exterior which protects said interior compartment from the vagaries of moisture, mud, dirt and debris during transport, comprising:
The electrical audio processing system of claim 1 wherein said vehicle is self-propelled by a self-contained motive power system.
The electrical audio processing system of claim 2 wherein said means for providing electricity further comprises a means for inducing electricity from self-contained motive power system motive power and a means for distributing said induced electricity solely to said electrical audio processing system.
The electrical audio processing system of claim 3 further comprising a means for storing a sufficient quantity of said induced electricity for powering said electrical audio processing system through a broadcast of a coherent audio program without inducing additional electricity from said inducing means during said coherent audio program.
The electrical audio processing system of claim 1 further comprising a means for changing a second one of said plurality of frequency segregated output components into a high frequency audible sound-wave of frequency higher than said low frequency audible sound wave;
The electrical audio processing system of claim 1 further comprising a second means for selectively conducting low-frequencies within said low frequency audible sound wave from said converting means through said vehicle exterior in a second direction different from said first direction.
The electrical audio processing system of claim 1 further comprising a means for controlling said amplifying means and said selecting means from a remote location to control said selecting and said amplifying.
The electrical audio processing system of claim 1 further comprising a means for forming an electrical signal from an audible sound;
The electrical audio processing system of claim 8 wherein said audible sound comprises a human voice, and said formed electrical signal is selected by said selecting means, whereby said human voice is amplified and broadcast through said vehicle exterior into public areas.
The electrical audio processing system of claim 8 wherein said forming and conveying means comprise a wireless diversity microphone.
A full-feature remote broadcast vehicle which is continuously setup and which is simultaneously secured against theft and vandalism in operation and while idle, comprising:
The remote broadcast vehicle of claim 11 further comprising an infra-red communications link between said remote control and said remotely controlled selector switch.
The remote broadcast vehicle of claim 11 wherein said port comprises a tuned port which selectively enhances a narrow low frequency bandwidth of said audible sound wave.
The remote broadcast vehicle of claim 13 further comprising additional loudspeakers mounted within said remote broadcast vehicle for converting electrical signals into additional audible sound waves;
The remote broadcast vehicle of claim 13 further comprising a second tuned port coupled from said converting means through said vehicle exterior which emanates said low frequency audible sound wave exterior to said vehicle in a second direction different from said first direction.
The remote broadcast vehicle of claim 11 further comprising an up-link mounted within said vehicle for transmitting said selector switch output to a central broadcast facility for further retransmission therefrom.
The remote broadcast vehicle of claim 11 wherein said electrical source comprises an electrical alternator which is isolated from an electrical system used by said vehicle for traffic signaling.
The remote broadcast vehicle of claim 11 further comprising a battery bank mounted within said vehicle for storing said electrical energy.
The remote broadcast vehicle of claim 11 wherein said player is selected from a CD player, a tape player and a DVD player.
The remote broadcast vehicle of claim 11 wherein said broadcast receiver further comprises a broadcast radio receiver.
The remote broadcast vehicle of claim 11 wherein said microphone transmission receiver receives said electrical transmission signal without wires through at least two reception paths.
The combination of a speaker for converting electrical signals to audible sounds and a vehicle having an exterior body forming an enclosed space within said vehicle and having access portals through which a human may pass for entry into said enclosed space and exit therefrom, wherein the improvement comprises:
The combination of a speaker and a vehicle of claim 22 further comprising a second tuned port for selectively transmitting a limited bandwidth of said audible sounds from said enclosed space through said exterior vehicle body.
The combination of a speaker and a vehicle of claim 23 wherein said second tuned port transmits said audible sounds in a direction different from said first tuned port.
The combination of a speaker and a vehicle of claim 24 further comprising a third tuned port for selectively transmitting a limited bandwidth of said audible sounds from said enclosed space through said exterior vehicle body in a direction different from said first and second tuned ports.
