Abstract

Tuned tube electromagnetic warning device, of the "trap" type, characterized by the fact that the ratio of the section of the end of the chamber that flows into the open air with the free surface of the vibrating membrane, multiplied by the fundamental vibration frequency of the flag, is equal to a number between 500 and 680, and preferably equal to 590.
