Patent ID: 8371250

Claim:
A volume sensitivity adjustable bark suppression device configured to be worn on the collar of a dog comprising: a ported rigid enclosure; at least one suspension mount; at least one suspension means comprising a wound spring having a distal end and a proximate end; at least one non-powered audible frequency generator; and at least one volume adjustment control; wherein said non-powered audible frequency generator is a tuning fork; wherein said suspension mount is affixed to an inside surface of said enclosure with said proximate end of said wound spring linearly affixed to said suspension mount, said distal end of said wound spring linearly affixed to said tuning fork such that said tuning fork is linearly suspended and spaced from the interior surfaces of said enclosure at rest and wherein said distal end of said wound spring is swingable within said enclosure when jostled by a barking dog an amount to overcome said wound springs resting tension enabling said tuning fork to strike said inside surface of the enclosure resulting in dog audible frequency generation from said tuning fork; wherein said volume adjustment control resides on and extends from said inside surface of said enclosure, adjacent said wound spring and comprises a threaded boss housing a threaded adjustable back swing dampening member that can be threadingly advanced toward said tuning fork to restrict back swing motion of said tuning fork thereby controlling the volume of said audible frequency generated during operation.
