Abstract

UN GENERADOR DE ENERGIA DE ONDA ACUSTICA COMPRENDE UN CUERPO QUE TIENE UNA PRIMERA CAMARA 1 PRESURIZABLE CON GAS, JUNTO A UNA SEGUNDA CAMARA 2 DENTRO DE LA QUE SE INTRODUCE UN LIQUIDO PARA CUBRIR UN MEDIO DE VIBRACION 4 QUE PUEDE SER UN DIAFRAGMA FLEXIBLE Y ESTA MONTADO SOBRE LA SEGUNDA CAMARA, DE MANERA QUE CIERRE UNA ABERTURA ASOCIADA 5 EN LA SEGUNDA CAMARA. DESPUES DE QUE LA PRIMERA CAMARA 1 SE PRESURIZA CON UN PRIMER GAS, UNA ABERTURA CERRADA COMUN ENTRE LAS CAMARAS SE ABRE PARA CHOCAR CON EL LIQUIDO. COMO RESULTADO, LOS MEDIOS DE VIBRACION 4 AL VIBRAR PRODUCEN LA ENERGIA DE ONDA ACUSTICA EN RESPUESTA A LA INCIDENCIA DE LA ONDA DE CHOQUE SOBRE EL LIQUIDO. MEDIANTE EL USO DE DIFERENTES LIQUIDOS Y/O DIFERENTES ALTURAS DE LIQUIDOS EN LA SEGUNDA CAMARA, SE PUEDE SINTONIZAR EL GENERADOR PARA PROPORCIONAR ENERGIA DE ONDA ACUSTICA CON UNA GAMA DE FRECUENCIA ELEGIDA RELATIVAMENTE ESTRECHA, O DENTRO DE UNA FRECUENCIA UNICA SUSTANCIALMENTE ELEGIDA.
