Abstract

El altoparlante (10, 110, 210, 310, 510, 610, 710, 810) está compuesto por un diafragma (12, 112, 212, 312, 512, 712, 812) con un perímetro externo (24,124, 224, 324, 524, 624, 724, 824), una bobina movil (18, 118, 218, 318, 518, 618, 718, 818),u na estructura (26, 126, 226, 326, 526, 626, 726, 826) parasoportar el diafragma (12, 112, 212, 312, 512, 612, 712, 812), y un estator motriz (26, 126, 226, 326, 526, 626, 726, 826) que suministra un campomagnético en el cual se sostiene labobina movil (18, 118, 218, 318, 518, 618, 718, 818). La corriente a través de la bobina movil (18, 118, 218, 318, 518,618, 718, 818) alterna la bobina movil (18, 118, 218, 318, 518, 618, 718, 818) y el diafragma (12, 112, 212, 312, 512, 612, 712,812) c onectado a la misma.Las nervaduras (43, 143, 243, 343, 543, 643, 743, 843) se extienden hacia afuera en el perímetro (24, 124, 224, 324, 524, 624, 724, 824) del diafragma(12, 112, 212, 312, 512, 612, 712, 812) para montar la bobinamovil (18, 1 18, 218, 318, 518, 618, 718, 818) al perímetro (24, 124, 224, 324, 524, 624, 724,824) del diafragma (12, 112, 212, 312, 512, 612, 712, 812). El estator motriz (26, 126, 226, 326, 526, 626, 726, 826) incluye por lo menos un retornodeflujo interno (32, 132, 232, 332, 532, 632, 732, 832) con ranuras (46, 146, 246, 346, 546, 646, 746, 846) por las que se extienden las nervaduras (43, 143,243, 343, 543, 643, 743, 843) entre el perímetro (24, 124, 224, 324, 524, 624, 724,824) del diafragma (12, 112, 212, 312, 512, 612, 712, 812) y la bobinamovil (18, 118, 218, 318, 518, 618, 718, 818). Alternativamente, el altoparlante (410) está compuesto por un diafragma (412) con un perímetroexterno (424) y un ejecentral (414, 416) que definen entre ellos una region relativamente interna (447) del diafragma (412) que se extiende hacia afuera
