Abstract

trata-se de um sistema de geração de efeito sonoro ativo (19) que inclui: um microfone de tubo de admissão (37) para detectar um sinal de ruído de vibração produzido em um tubo de admissão (39) de um motor de combustão interna (13); um alto-falante de assento do motorista (25) para emitir um som que inclui um efeito sonoro e um dispositivo de geração de efeito sonoro ativo (11). o dispositivo de geração de efeito sonoro ativo (11) inclui: um gerador de sinal de referência (55) para extrair um componente acústico que pertence a uma banda de frequência predeterminada com base em uma frequência giratória (fq) do motor (13) do sinal de ruído de vibração, e gerar um sinal de referência harmônico com base no componente acústico extraído; e um adicionador (ad2) para gerar um sinal de controle a ser usado para gerar o efeito sonoro com base no sinal de referência, e emitir o sinal de controle para o alto-falante de assento do motorista (25). o gerador de sinal de referência (55) define uma frequência central para o componente acústico com base na frequência giratória (fq) do motor (13).
