An apparatus comprising a variable acoustic source and a microphone, both acoustically coupled to a volume having a fluid region and an air region. The apparatus also can include a processor to determine a volume of the air region based on signals received from the microphone and the variable acoustic source. A fluid valve is coupled to the processor, and is configured to allow an amount of fluid to exit the fluid region associated with the volume of the air region. An atomizer, coupled to the fluid region, is configured to aerosolize at least a portion of the fluid.
L'invention concerne un appareil comportant une source acoustique variable et un microphone, ces deux éléments étant acoustiquement couplés à un volume doté d'une zone de fluide et d'une zone d'air. L'appareil peut également comprendre un processeur pour déterminer un volume de la zone d'air sur la base de signaux reçus du microphone et de la source acoustique variable. Une vanne fluidique couplée au processeur est conçue pour permettre la sortie d'une quantité de fluide donnée hors de la zone de fluide associée, à un volume de la zone d'air. Un atomiseur couplé à la zone de fluide est conçu pour transformer en aérosol au moins une partie du fluide.
