Abstract

DISPOSITIVO ACÚSTICO que está compuesto por un elementodependiente de una acción de onda de flexión con distribución ventajosa de modos de resonancia, donde el elemento tiene su área activa acústicamente y al menos parcialmente limitada por unos medios que tienen en cuenta la naturaleza sustancialmente de fijación en relación a la vibración de onda de flexión. La operación puede ser por debajo de la coincidencia o por encima si se desea por los dispositivos acústicos activos aún más que tienen una localización ventajosa de medios transductores de onda de flexión determinado con referencia a y teniendo en cuenta tales medios de limitación.ACOUSTIC DEVICE which is composed of an element dependent on a bending wave action with advantageous distribution of resonance modes, where the element has its acoustically active area and at least partially limited by means that take into account the substantially fixing nature in relation to bending wave vibration. Operation may be below coincidence or above if desired by still more active acoustic devices having an advantageous location of bending wave transducer means determined with reference to and taking such limiting means into account.
