Abstract

resumo “transdutor eletromecânico-eletroacústico com baixa espessura e alta faixa de deslocamento e método de fabricação relevante” trata-se de um transdutor eletroacústico (1) revelado que compreende: um conjunto magnético em formato de anel (3) que gera um campo magnético, uma suspensão elástica (4) conectada ao conjunto magnético, um suporte (8) conectado à suspensão elástica e que sustenta uma bobina (6) adaptada para se mover no campo magnético gerado pelo conjunto magnético, e uma membrana acústica (5) conectada ao suporte (8) da bobina a fim de vibrar e emitir um som. o conjunto magnético (3) compreende: uma estrutura fina de alojamento e sustentação (7) produzida a partir de material não magnético, e uma pluralidade de ímãs (30) com eixo geométrico magnético (a) e anisotropia axial, sendo que os ditos ímãs (30) são dispostos lado a lado, dentro da dita estrutura fina de alojamento e sustentação (7) que age como estrutura de mancal para o transdutor e como estrutura de contenção para os ímãs. 1/1
