Abstract

um microfone de diafragma duplo pode ser utilizado para reduzir ou eliminar um componente do sinal de saída devido à aceleração do microfone. o microfone de diafragma duplo pode incluir um primeiro componente detector de sons que inclui um primeiro diafragma afastado de um primeiro elétrodo e configurado para gerar um primeiro sinal e um segundo componente detector de sons que inclui um segundo diafragma afastado de um segundo elétrodo e configurado para gerar um segundo sinal. o primeiro componente detector de sons e o segundo componente detector de sons são orientados em direções opostas e incluem um conjunto de circuitos eletrônicos configurado para somar os primeiro e segundo sinais de saída de modo a se gerar um sinal de saída combinado substancialmente não afetado pela aceleração do microfone.
