ABSTRACT:
A combined and integrated audible and visual signal. A signal case is constructed of a light transmissive material and includes an exposed front end cover with one or more sound transmitting apertures and a tubular wall extending transversely from the exposed end cover for extending through a hole in a mounting panel. A transducer is mounted within the tubular wall and includes a diaphragm that is spaced from the exposed cover. Light sources are mounted to face the diaphragm. The tubular wall in the region between the cover and a plane transverse to the tubular wall through the diaphragm is, in the axial direction, smoothly continuous with no angled bends.
