Abstract
A signal device, particularly for use in areas at risk of explosion, has a housing, at least one light source, and at least one acoustics source. A sound guidance unit follows the acoustics source with its neck opening and emits the sound produced by the acoustics source to the outside, by way of its mouth opening. The sound guidance unit not only serves to guide sound, but at the same time takes on an optical signal function.
