Dual acoustic horn assembly

摘要

An acoustic horn assembly for use as part of an electronic siren system for an emergency vehicle comprises a pair of integrated molded, rigid plastic members which cooperate to define a pair of divergent sound passages. The entrance ends of these sound passages are displaced do that they may be coupled to separate sound generators, the sound generators being supported from respective vehicle frame side rails. The sound generators are coupled to the sound passage entrance ends by adjustable length sound transmission conduits which are in the form of elbows.
