The invention relates to a device (100) for nebulizing a liquid, comprising: a vessel (110) that is open at the top portion thereof and configured so as to contain the liquid to be nebulized; at least two ultrasonic-wave generators (120, 130) for emitting at least two ultrasonic-wave fronts (122, 132) into the liquid; and at least two means (134, 124) for focusing the ultrasonic waves, each of which engages with one of said generators (120, 130) in order to concentrate ultrasonic waves at a single point P less than ten millimetres from the free surface of the liquid, wherein the vibration frequencies of the two wave fronts (122, 132) are different. Le dispositif (100) de nébulisation d'un liquide comporte une cuve (110) ouverte dans sa partie supérieure et configurée pour contenir le liquide à nébuliser, au moins deux générateurs (120, 130) d'ondes ultrasonores destinés à émettre au moins deux fronts (122, 132) d'ondes ultrasonores dans le liquide, au moins deux moyens (134, 124) pour focaliser des ondes ultrasonores, coopérants chacun avec un dit générateur (120, 130) pour concentrer des ondes ultrasonores en un même point P à moins de dix millimètres de la surface libre du liquide, dans lequel les fréquences de vibration des deux fronts d'ondes (122, 132) sont différentes.
