Patent ID: 7908924

Claim:
A sound focusing mechanism for generating a focused source of sound, comprising: a housing, wherein the housing includes at least one wall which defines a central cavity, wherein one end of the housing has an opening formed therein; a sound generating device for generating a sound is located within the central cavity; an actuator assembly operatively connected to the sound generating device for selectively operating the sound generating device, the actuator assembly including a control remote from the sound generating device to cause the sound generating device to emit a sound for a short duration of time or continuous sound; and a controller for selectively controlling the frequency of the sound generated by the sound generating device to emit a single frequency sound within a range of about 50 Hz to about 5,000 Hz or to perform a sweep in frequency within a range of about 50 Hz to about 5,000 Hz, wherein the wall limits transmission of the sound generated by the sound generating device such that a focused sound is emitted from the sound focusing mechanism through the opening.
