Abstract
An electromechanical horn having a sound generating system including a piezoelectric speaker generates a series of short, audible sound signals in a repetitive pattern, the generated sound signals having fundamental frequencies with associated harmonic component frequencies and decibel levels that fall within a frequency range of greatest hearing sensitivity of the animal to disperse or deter an aggressive animal in a non-detrimental manner. The generated sound signals have fundamental frequencies with associated harmonic component frequencies that fall within a frequency range of from about 3 kHz to about 10 kHz, and decibel levels in a range of from about 75 dB to about 115 dB (SPL) at 1 meter. The horn device can be hand-held, attached to a user's belt or clothing, or removably attached to a bicycle, motorcycle, stroller, or other conveyance or object and can be actuated while attached or quickly removed and actuated when needed.
