Abstract

uma unidade de cálculo para um sistema de reprodução de som compreende meios de entrada, um processador e, pelo menos, três saídas para controlar, pelo menos, três transdutores de uma matriz. os meios de entrada têm a finalidade de receber um fluxo de áudio a ser reproduzido utilizando a matriz, caracterizado pelo fluxo de áudio ter uma faixa de frequência. o processador é configurado para calcular três sinais de áudio individuais a serem emitidos utilizando, pelo menos, três saídas, de modo que um primeiro diferencial acústico tendo uma segunda ordem ou uma ordem mais alta seja gerado utilizando a matriz.
