Abstract

TRANSDUTOR ACÚSTICO COM PROPRIEDADES EQUILIBRADAS. O transdutor acústico compreende uma parte superior (301) e uma parte inferior (302), com um primeiro ímã permanente (303) na parte superior (301) e um segundo ímã permanente (304) na parte inferior (302). Pólos magnéticos com nomes semelhantes do primeiro e segundo ímãs permanentes (303, 304) estão voltados um para o outro. Uma tampa superior (306) na parte superior (301) e uma tampa inferior (307) na parte inferior (302) compreendem material magnético e definem um invólucro em torno dos ímãs (303, 304). Uma bobina (308) cria, sob a influência de uma corrente elétrica, forças magnéticas dinâmicas. Uma folga de separação (309) entre as bordas da referida tampa superior (306) e da tampa inferior (307) é direcionada de modo a permitir um movimento relativo das bordas da referida tampa inferior (307) e da referida tampa superior (306) entre diferentes posições, as referidas posições diferem na medida em que as bordas da referida tampa superior (306) e da tampa inferior (307) coincidem.
