Abstract

ACCIONADOR-TRANSDUCTOR PIEZOELECTRICO (1) PARA SISTEMAS REPRODUCTORES DE SONIDO. CONSTA DE UNA PLACA CERAMICA FINA (2) QUE SE FIJA A UN PANEL VIBRATORIO (P) QUE FORMA PARTE DE UNA ESTRUCTURA COMO LA CARROCERIA DE UN VEHICULO O SIMILAR. LA PLACA CERAMICA (2) ESTA ENCAJADA EN UN RECIPIENTE BASICAMENTE CON FORMA DE BANDEJA (4) REALIZADO CON UN MATERIAL RELATIVAMENTE FLEXIBLE CON UN BORDE PERIFERICO (5) QUE CUENTA CON UNA CAPA ADHESIVA (6) Y UN ALOJAMIENTO (7) EN EL QUE SE ALBERGA LA PLACA CERAMICA. LA CARA DE FIJACION (2A) DE LA PLACA ESTA DISPUESTA EN UN PLANO MAS BAJO CON RESPECTO A LA CAPA ADHESIVA (6) DEL BORDE PERIFERICO (5). ENTRE EL BORDE PERIFERICO (5) Y EL ALOJAMIENTO (7) DE LA PLACA CERAMICA SE FORMA EL RECIPIENTE (4) CON UN RECEPTACULO (9) DISPUESTO PARA CAPTURAR CUALQUIER CANTIDAD SOBRANTE DE ADHESIVO ESTRUCTURAL (14) MEDIANTE EL CUAL SE FIJA LA PLACA CERAMICA (2) AL PANEL (P).
