Abstract

"CIRCUITO ELETRôNICO DE CONTROLE E DISPOSITIVO DE EMISSãO DE SINAL ACúSTICO PARA VEíCULOS". A presente refere-se a um circuito eletrônico de controle (50) de um alto-falante (LDSK) para emitir pelo menos um primeiro sinal acústico característico de uma sirene de alarme é caracterizado pelo fato de que ele compreende: dispositivo de armazenamento (Flash) para armazenar uma pluralidade de amostras digitais representativas de pelo menos uma parte de um sinal acústico de referência que pode ser gerado por um dispositivo de aviso acústico de amostra, dispositivo de processamento (<109>P) para gerar, baseado na pluralidade de amostras, um sinal elétrico modulado (S1, S2) transportando pelo menos uma parte do conteúdo harmônico associado com o sinal acústico de referência e um circuito acionador (DRV-CR) para receber o sinal elétrico modulado (S1; S2) e fornecer para o alto-falante (LDSK) um sinal de acionamento correspondente para a emissão de um segundo sinal acústico substancialmente reproduzindo a pelo menos uma parte do sinal acústico de referência.
