Improved laringofono device, of the type that is constituted by a cylindrical chamber, which has one of its bases prolonged in a frustoconical duct, the opposite base being closed by means of a top that extends into another duct for installation of a flexible cannula, essentially characterized in that a static core comprising: a) an axial hole extending the frustoconical duct is coupled to the inside of the cylindrical chamber; b) an arrangement of radial offices communicated with said axial hole and c) an extreme platform that divides the cylindrical chamber into two sections, of which the upper one is communicated with the axial hole of the core, while the lower section of the chamber it is communicated with the radial holes of the latter, including in the upper section of the chamber a floating membrane with radial tabs forming pneumatic passages combined with another valvular membrane that sits at the base of the chamber on an arrangement of openings communicating with the outside.
