Sound and light emitting fish lure and method of attracting fish

摘要

A fishing lure emits continuous sine wave generated sounds to emulate the sounds produced by fish themselves. A waterproof casing contains electronic circuitry that includes a precision oscillator integrated circuit for generating a continuous sine wave sound that is swept about a predetermined center frequency of approximately 3.0 kHz and that extends between a low frequency of approximately 1.8 kHz and a high frequency of approximately 4.2 kHz. The output of the precision oscillator is coupled to a miniature piezoelectric speaker for audibly reproducing the generated sine wave sound. An LED flasher integrated circuit coupled to the precision oscillator integrated circuit serves to control a light emitting diode to flash at a predetermined rate or be constantly lit to thereby act as an additional fish attractor in combination with the emitted continuous sine wave sound.
