A piezoelectric audible signal that has at least two, frusto-conical, coil spring conductors extending between and in unsoldered electrical connection with, at one end, different contact pads on the printed circuit board and, at their opposite ends, the piezoelectric disk. A retaining and spacer ring is interposed between the disk and the printed circuit board and has at least two, frusto-conically shaped, spring retaining cavities that matingly receive the spring conductors in a manner that retains the spring conductors against movement away from the printed circuit board when the ring is attached to the printed circuit board.

Piezoelectric audible signal with spring contacts and retaining and spacer ring

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.
