Abstract

LA INVENCION SE REFIERE A DISPOSITIVOS ACUSTICOS QUE TIENEN ELEMENTOS QUE SE EXTIENDEN TRANSVERSALMENTE DE ESPESOR Y CAPACES DE SOPORTE DE ONDAS DE FLEXION QUE ORIGINAN UNA ACCION ACUSTICA CONSECUENTE DEBIDO A LA DISTRIBUCION ESPACIAL DE MODOS RESONANTES DE VIBRACION DE LA ONDA DE FLEXION NATURAL EN CONSONANCIA CON LA ACCION ACUSTICA CONSEGUIBLE REQUERIDA DE DICHO ELEMENTO A TRAVES DE UNA GAMA DE FRECUENCIAS ACUSTICAS OPERATIVAS DESEADAS. LA DISTRIBUCION ESPACIAL DE LA RIGIDEZ INCLUYENDO SUS VARIACIONES SE UTILIZA PARA OBTENER EMPLAZAMIENTOS DESEADOS PARA TRANSDUCTORES DE ONDAS DE FLEXION Y/O UNA ACCION ACUSTICA DE MODO RESONANTE CORRECTA A PARTIR DE PERFILES INHERENTEMENTE DESFAVORABLES DE LOS ELEMENTOS. LA INVENCION SE REFIERE TAMBIEN A ELEMENTOS CON ACCION PISTONICA COMBINADA Y EXCITACION DE ONDAS DE FLEXION EN CENTROS DE MASA Y GEOMETRIA.THE INVENTION CONCERNS ACOUSTIC DEVICES THAT HAVE ELEMENTS THAT ARE EXTENDED CROSS-THICKNESS AND FLEXION WAVES SUPPORT CAPABLES THAT ORIGINATE ACOUSTIC ACTION CONSEQUENTIALLY DUE TO THE SPACE DISTRIBUTION OF VIBRALEX NATURAL RESOURCES IN VIBRALEX NATURE REQUIRED ACOUSTIC ACTION REQUIRED OF SUCH ELEMENT THROUGH A RANGE OF DESIRED OPERATIVE ACOUSTIC FREQUENCIES. THE SPACE DISTRIBUTION OF THE RIGIDITY INCLUDING ITS VARIATIONS IS USED TO OBTAIN DESIRED PLACEMENTS FOR FLEXION WAVE TRANSDUCERS AND / OR AN ACOUSTIC ACTION OF A CORRECT RESONANT MODE FROM INHERENTLY UNFAVORABLE PROFILES OF THE UNFORGETTABLE PROFILES. THE INVENTION REFERS ALSO TO ELEMENTS WITH COMBINED PISTONIC ACTION AND EXCITATION OF FLEXION WAVES IN MASS AND GEOMETRY CENTERS.
