Abstract

A mobile audio mesh distribution (MAD) system/method allowing synchronized audio distribution to modular audio modules (MAMs) and/or drone delivery aircraft (DDA) in mesh audio network (MAN) is disclosed. The system/method utilizes a computer control system (CCS) that communicates wirelessly using a plurality of RF transceivers (RFT) over a RF mesh network (RMN) with one or more MAM that are configured to independently communicate with each other and automatically determine if audio updates are required from the CCS. The MAM are configured to query other MAMs in the RMN to determine if a connected MAM has updated audio/text (UAT), and if so, to download the UAT and schedule audio playback on a speaker. Messages may be transmitted to the MAM in the event of an emergency, terrorist event, or a physical event detected (PED) using prerecorded or updated audio that trigger immediate or scheduled playback by the MAM.

Dependent claims

A mobile audio mesh distribution (MAD) system comprising:

(a) computer control system (CCS);
and
(b) a plurality of modular audio modules (MAM);
wherein:
said CCS comprises:
(1) digital computer control (DCC);
(2) WiFi radio frequency transceiver (WRT);
and
(3) emergency radio frequency transceiver (ERT);
said MAM each comprises:
(1) WiFi radio frequency transceiver (WMT);
(2) emergency radio frequency transceiver (EMT);
(3) digital audio control (DAC);
(4) global positioning system (GPS) real-time clock (RTC);
(5) local audio storage (LAS);
(6) audio playback recorder (APR);
and
(7) audio amplifier/speaker (AAS);
said DCC is electrically coupled with said WRT and said ERT;
within each of said MAM, said DAC are each electrically coupled with their respective WMT, EMT, RTC, LAS, and APR;
within each of said MAM, said APR is electrically coupled with said AAS;
within each of said MAM, said LAS is configured to store digital audio information;
said CCS is configured to transmit using said DCC an emergency message event (EME) via said ERT to at least one of said MAM for reception by said EMT on said at least one of said MAM;
said MAM are each configured to receive said EME via said EMT under control of said DAC;
said DAC is configured to emit an emergency audio message (EAM) via digital transmission to said APR and audio signaling to said AAS upon receipt of said EME;
said CCS is configured to transmit a master CONFIG file (MCF) to at least one of said MAM via communication between said WRT and said WMT;
said master CONFIG file comprises an audio file list (AFL);
said AFL comprises a paired list of audio playback filenames (AFN) and their playback date/time/event triggers (PDT);
said DAC are each configured to request said master CONFIG file (MCF) using said WMT from another of said MAM;
said DAC on each of said MAM are each configured to compare a local CONFIG file (LCF) stored on said LAS of said MAM to any MCF received from another of said MAM and if these files differ, to update said LCF with the contents of said MCF and request a download of any AFN not present on said MAM from another MAM to said LAS;
said DAC on each of said MAM are each configured to compare date/time information from said RTC to said PDT and emit audio data from one of said AFN to said APR;
said APR is configured to receive digital audio signals (DAS) from said DAC and convert said DAI to analog audio signal levels (ASL);
and
said AAS is configured to receive said ASL from said APR and emit amplified audio on a speaker.
