Abstract
L'avvisatore comprende un involucro di sopporto (1 a 3) nel quale sono vincolate le periferie di due diaframmi (10, 11) affacciati fra i quali è definita una camera a volume variabile (12) che comunica con un condotto acustico (50, 51, 70) d'uscita. A tali diaframmi (10, 11) sono connesse rispettive armature (17, 18) ferromagnetiche contrapposte. Un solenoide di comando (15) quando viene eccitato con una corrente intermittente provoca movimenti in opposizione delle armature (17, 18) e la vibrazione in controfase di detti diaframmi (10, 11).Figura 4.
