Abstract:
The pest animal repulsing apparatus comprising:transducers that convert an electrical signal to a mechanical vibration;a random signal generating unit that generates a random signal;a source output on/off control unit that turns an output from a source on and off based upon an output from said random signal generating unit;a frequency varying unit that causes changes in frequency over time of the electrical signal provided to said transducers at a specific rate; andan output switching unit connected with said transducers and having two or more output systems for receiving power supplied from the source, wherein said output switching unit switches among said output systems to which the electrical signal is to be provided every time the output from the source is turned off and provides the electrical signal to said transducers in said output systems that have been switched to when the output from the source is turned on.
