A phonolaring apparatus, of the type comprising a hollow body, shaped like a receptacle, where a vibrating membrane is housed, on which a narrow passage impinges on the extension of the cap that fixes the position of the membrane, whose cap has a conduit external prolonged in a flexible extension, while below the membrane, the body is extended to a conical extension, and is characterized by the fact that the conical extension adaptable to the tracheal valve has a radial derivation in which it is located a membrane, mounted on a ring of greater diameter, and suspended from said ring through a radial appendix, while the ring is fixed to the housing by a screw cap, provided with an axial passage facing the valve, whose cap has internally a conical projection of smaller diameter than the membrane, so that the latter allows the entry of air into the interior during the aspiration, preventing its exit during expiration, to direct it towards the first vibrating membrane of the main body.
