Abstract
An electronic horn of compact dimensions. Oscillator circuits coupled to a mixing node produce a multiple frequency signal used to drive a horn transducer. One horn replaces the two horns used in the prior art. A reverberating chamber in close proximity to the transducer includes a cone shaped structure having multiple spiraling reflecting walls connected to the convex surface of the cone. Sound waves emitted by the transducer reverberate within the chamber as they bounce off the reflecting walls.
