Abstract

Foreliggende oppfinnelse angår et elektroakustisk transduserarrangement for undervannsantenner, som innbefatter transduserelementer (11) i innbyrdes avstand fra hverandre, en reflektor (12) som, i en lydinnfallsretning, er anordnet bak transduserelementene (11), hvilken reflektor innbefatter en metallplate (13) vendt mot transduserelementet (11) og en skummaterialeplate (14) lokalisert på den siden av metallplaten (13) som vender bort fra transduserelementene (11), og et hardt og omsluttende støpt element av elastomer som inneslutter transduserelementet (11) og reflektoren (12) . Oppfinnelsen har til hensikt å skaffe et transduserarrangement av lav vekt med uendrede, fordelaktige ytelsesdata med et bredt anvendelsesområde. For dette formål har metallplaten (13) en bikubestruktur (honeycomb-stmktur), og et dobbeltlag (15) som utgjøres av et lag av skummateriale (16) tilstøtende metallplaten (13) og et lag av kork (17) tilstøtende platen av skummateriale (14) er anordnet mellom metallplaten (13) og platen av skummateriale (14).
