Abstract
Improved electro-acoustic warning device, characterized essentially by being constituted by a box provided in its cover with a series of holes for sound output, housing the corresponding motor inside and which is surrounded by a "C" piece whose upper sheet constitutes the vibrating membrane, the intermediate one is of smaller width and centrally grooved to increase its flexibility and sensitivity of the membrane and the lower one, it is under the core and fixed like this with a single central screw through lower.
