Abstract

"ELEMENTO PASSIVO EM VOLUME FECHADO PARA ALTO-FALANTE" Volumes vazios (1) usualmente existentes em painéis traseiros, portas e similares em veículos a motor, são usados para constituírem caixas de volume de ar fechado para alto-falantes "ativos" (6) combinados com respectivas membranas "passivas" calibradas (7). Os sistemas acústicos obtidos recriam, nos volumes (1) disponíveis em veículos a motor, as mesmas situações de aumento de eficiência de alto-falantes em baixas freq³ências, as dimensões sendo as mesmas, por serem obtidas em caixas pré-arranjadas onde elementos passivos, localizados em abafadores, operam de acordo com os citados alto-falantes e utilizam os mesmos volumes fechados de ar, criados nas citadas caixas."PASSIVE ELEMENT IN CLOSED VOLUME FOR SPEAKER" Empty volumes (1) usually existing in rear panels, doors and the like in motor vehicles, are used to constitute closed air volume boxes for "active" speakers (6) combined with respective calibrated "passive" membranes (7). The acoustic systems obtained recreate, in the volumes (1) available in motor vehicles, the same situations of increased efficiency of loudspeakers at low frequencies, the dimensions being the same, as they are obtained in pre-arranged boxes where passive elements, located in dampers, operate according to the aforementioned speakers and use the same closed volumes of air, created in the aforementioned boxes.
