Abstract

Urządzenie do gaszenia płomieni falami akustycznymi posiadające obudowę, w której zainstalowany jest generator akustyczny wraz z modulatorem, połączonym ze wzmacniaczem audio, zasilane akumulatorowo i sieciowo, przy czym do obudowy przymocowana jest tuba, stanowiąca komorę, z zainstalowaną nakładką zmniejszającą jej wylot, przez który przechodzą fale akustyczne generowane z głośnika niskotonowego, charakteryzuje się tym, że do obudowy (1) urządzenia, we wnętrzu tuby (2), przymocowane są kliny skierowane w stronę nakładki (4), na których nawinięty jest pochłaniacz, przy czym kliny oraz pochłaniacz wykonane są z materiałów silnie absorbujących fale akustyczne emitowane przez tylną powierzchnię membrany głośnika (3). Korzystnie, pochłaniacz ma postać wełny szklanej lub wełny owczej, zaś kliny mają zarys graniastosłupów o podstawie trójkąta i są wykonane z wełny szklanej lub wełny skalnej.A device for extinguishing flames with acoustic waves having a casing in which an acoustic generator with a modulator is installed, connected to an audio amplifier, battery and mains powered, the casing is attached to the casing, which is a chamber with an overlay installed reducing its outlet through which acoustic waves generated from the subwoofer, characterized by the fact that wedges directed towards the cap (4) on which the absorber is wound up are attached to the housing (1) of the device, inside the tube (2), with the wedges and absorber being made from materials strongly absorbing acoustic waves emitted by the rear surface of the speaker membrane (3). Preferably, the absorber is in the form of glass wool or sheep's wool, and the wedges have the shape of a prism with a triangle base and are made of glass wool or rock wool.
