Supersonic transducer

Abstract

The invention discloses an ultrasonic transducer which relates to the mobile communication field. The ultrasonic transducer comprises an input filter, an output controller, an oscillation thruster, an inverting circuit and a transduction output transformer; the input filter limits current and filters wave of the input direct currents; stable direct currents are input at the output end of the input filter; the input end of the output controller is connected with the output end of the input filter; the output of ultrasonic waves is controlled by controlling the transfer of the direct currents; the input end of the oscillation thruster is connected with the output end of the output controller and the output end of the oscillation thruster is connected with the input end of the inverting circuit; the oscillation current is input to the inverting circuit; the inverting circuit changes and outputs the frequency of the oscillation current; the input end of the transduction output transformer is connected with the output end of the inverting circuit; the ultrasonic wave is output with a frequency ranging from 0 to 20 Hz. By using the ultrasonic transducer, the fishing can be more convenient and the fish are not killed, which is beneficial to the principle of 'catching the big fish, releasing the small fish', thus realizing ecological equilibrium.

Description

technical field [0001] The invention relates to the field of conversion between electric energy and ultrasonic waves, in particular to an ultrasonic transducer used for fishing. Background technique [0002] At present, there are many professional fish farming households in our country. When they are harvesting or checking the health status of fish, they still use relatively primitive and clumsy fishing methods, such as electric shocks, pesticides, explosives, sound lures, fishing nets, etc. These methods easily lead to the death of fish, causing large-scale pollution of water bodies, and the death of large and small fish together. Contents of the invention [0003] An embodiment of the present invention provides an ultrasonic transducer. Using the ultrasonic transducer can make fishing more convenient and prevent fish from dying, which is beneficial for catching large and letting go of small to achieve ecological balance. [0004] The ultrasonic transducer provided by th...

[0002] At present, there are many professional fish farming households in our country. When they are harvesting or checking the health status of fish, they still use relatively primitive and clumsy fishing methods, such as electric shocks, pesticides, explosives, sound lures, fishing nets, etc. These methods easily lead to the death of fish, causing large-scale pollution of the water body, and the death of both large and small fish. It is impossible to maintain ecological balance without letting go of large and small fish.
