Abstract
L'invention se rapporte au domaine de l'acoustique et permet de générer des ondes acoustiques dans un milieu gazeux (de l'air), et peut être utilisée afin de générer des ondes acoustiques qui peuvent entre autres être perçues par l'oreille humaine à des fins domestiques ou industrielles. Le dispositif de génération d'ondes acoustiques comprend un ioniseur comprenant une électrode ionisante (1) faite d'un matériau électro-conducteur, et au moins une électrode de commande (2) faite d'un matériau électro-conducteur. En fonction de la forme de réalisation des électrodes (1, 2) elles peuvent être disposées de manière parallèle, concentrique ou coaxiale. La surface de l'électrode ionisante (1) comprend des protubérances (3) de grande courbure, par exemple en forme d'aiguilles dont les extrémités sont orientées vers l'électrode de commande (2) qui laisse passer le son grâce à la présence d'ouvertures (3), et se présente par exemple sous forme d'un réseau, tandis que sa surface est recouverte d'une couche (4) d'un matériau ayant une grande résistance spécifique, comme un revêtement synthétique à base de résine époxy, ou comprend des zones formées par l'alternance d'un diélectrique, comme du polyéthylène ou du vinyle, et d'un conducteur (dont le matériau sert pour l'électrode de commande). La superficie totale de la surface des zones de diélectrique est supérieure à la superficie des zones du conducteur. Les électrodes (1, 2) sont connectées en parallèle à une source de tension électrique (4) et à un modulateur de signal électrique (5). Selon une seconde variante, les électrodes se présentent sous forme d'un massif de conducteurs ayant une grande surface courbe, le massif des deux électrodes étant orienté vers des électrodes qui lui sont adjacentes. Selon la seconde variante, l'invention comprend un ioniseur (1) qui est formé par deux électrodes équidistantes (2, 3) se présentant sous forme de massifs de conducteurs (éléments) ayant une grande surface courbe (4) et orientés vers le côté des électrodes qui leur font face, et qui est connecté à la source de tension (5) et au modulateur (6).
