Abstract
A fishing lure having a water-tight cavity has a wire spring within the cavity, one end of the spring being rigidly affixed to the lure body and the opposite end carrying a weight. The relationship between the cavity size and the weighted spring is such that the spring will oscillate freely within the cavity without the weight striking the cavity walls during normal movement of the lure through the water. Alternate forms of the invention utilize an electronic oscillator driven transducer to produce vibration of the lure body.
Claims4
A fishing lure comprising:
- a body member having walls defining a water-tight cavity;
- an elongated spring of a magnetically attractable material within said cavity and affixed at one of its ends to said wall;
- a weight affixed to the other end of said spring;
- an electromagnetic transducer mounted within said cavity in close proximity to said spring;
- a power source;
- and
- an oscillator circuit supplied by said power source and operable to drive said transducer at the resonant frequency of said weight and spring.
