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).PIEZOELECTRIC ACTUATOR-TRANSDUCER (1) FOR SOUND PLAYER SYSTEMS. IT CONSISTS OF A FINE CERAMIC PLATE (2) THAT IS FIXED TO A VIBRATORY PANEL (P) THAT IS PART OF A STRUCTURE LIKE THE BODYWORK OF A VEHICLE OR SIMILAR. THE CERAMIC PLATE (2) IS FITTED IN A BASICALLY TRAY-SHAPED CONTAINER (4) MADE WITH A RELATIVELY FLEXIBLE MATERIAL WITH A PERIPHERAL EDGE (5) THAT HAS AN ADHESIVE LAYER (6) AND A HOUSING (7) IN WHICH THE CERAMIC PLATE IS HOSTED. THE FIXING FACE (2A) OF THE PLATE IS ARRANGED ON A LOWER PLANE WITH RESPECT TO THE ADHESIVE LAYER (6) OF THE PERIPHERAL EDGE (5). BETWEEN THE PERIPHERAL EDGE (5) AND THE HOUSING (7) OF THE CERAMIC PLATE THE CONTAINER (4) IS FORMED WITH A RECEPTACLE (9) READY TO CAPTURE ANY EXCESSIVE AMOUNT OF STRUCTURAL ADHESIVE (14) BY WHICH THE PLATE IS FIXED (2) TO THE PANEL (P).
