Patent ID: 7109849

Claim:
In an environment comprising a power source for powering an amplifier circuit connected to at least one speaker for producing sound, a mosquito dispersing device comprising means for generating a mosquito dispersing pitch pattern having a frequency in the range of at least one of a wing beat frequency of a dragonfly and a wing beat frequency of a damselfly, from which a signal having a frequency of the mosquito dispersing pitch pattern can be produced for use with the amplifier circuit to direct the at least one speaker to produce vibrations of the mosquito dispersing pitch pattern in a dispersing area, wherein the means for generating a mosquito dispersing pitch pattern includes an integral converter and the mosquito dispersing pitch pattern is generated in a digital format from a digital storage medium, and the signal having a frequency of the mosquito dispersing pitch pattern is produced by the integral convener of the mosquito dispersing device for converting the mosquito dispersing pitch pattern from digital to analog, and wherein the digital storage medium has a plurality of distinct fixed frequency mosquito dispersing pitch patterns stored thereon in the range of about 20 to 40 hertz, and the device further comprises means for selecting a distinct pitch pattern from the plurality of distinct fixed frequency mosquito dispersing pitch patterns stored on the digital storage medium, whereby, mosquitos in the dispersing area can be diminished by at least one of fleeing upon sensing the vibrations of the mosquito dispersing pitch pattern and succumbing to an increased presence of at least one of dragonflies and damselflies attracted to the dispersing area by the vibrations of the mosquito dispersing pitch pattern, and a user of the mosquito dispersing device can selectively choose one of the plurality of distinct fixed frequency mosquito dispersing pitch patterns to affect mosquitos of varying sensitivities.
