Device for luring and driving fish by sound wave

Abstract

The invention provides an acoustic-wave fish attracting / driving device. The device utilizes acoustic waves to attract / drive targets, can effectively overcome the disadvantages that the prior art is high in manufacture and application cost, low in action efficiency, small in action range and application time range and severe in environmental pollution, has the advantages of low cost, fast far signal propagation, no limit on time and no environmental pollution, and can remarkably increase yield and income. The device consists of a sound source, a power amplifier, an acoustic generator, a power source, a switch, a shell and other parts, wherein audio signals sent by the sound source are subjected to power amplification, and corresponding acoustic waves are generated by the acoustic generator to attract or drive the targets.

Description

technical field [0001] The present invention is a sounding device that uses sound waves to lure or drive away fish and other targets, specifically a fish luring and fish-repelling device including sound sources, power amplifiers, sounding devices, power supplies, switches, and shells. Background technique [0002] In fishery fishing, fishing sports and aquaculture planting, in order to obtain the maximum harvest, the targets that want to be caught or fished should be lured and gathered or driven to suitable waters, or unfavorable objects should be driven away, so as not to harm the breeding and planting objects or affect Fishing, fishing. In the above-mentioned aspects, there has been no effective solution. In the past, the sense of smell, taste and vision of the target were mostly used to lure or drive away, but the effect was not very good. In terms of lure, such as bait (fishing and making nests), the bait diffuses slowly in the water, easily fades or even deteriorates, ...
