The Working Principle Of Ultrasonic Horn Making Mouse Repellent

The circuit schematic diagram of ultrasonic horn to make mouse repellent is shown in the figure below, 555 time-based integrated circuit is connected to a sweeping ultrasonic generator, the sweep signal is taken from the 50Hz power frequency signal on the secondary side of the transformer T, and is added to the control end of the 555 time-based integrated circuit by R3 to 5 pins, so as to achieve the purpose of changing the output pulse frequency. Using the data shown in the figure, the output frequency changes from 32 to 62kHz, and the electrical signal then radiates ultrasonic waves into space through the ultrasonic transducer B, which is reported to make mice feel irritable and can drive away mice within 16 meters, but the actual effect remains to be verified by enthusiasts.
Ultrasonic rodent control:
In hotels, homes and any place to kill rats, it is recommended to use invincible pioneer mouse repellent, ultrasonic electronic mouse repellent, rat exterminator using modern high-tech electronic technology, sonic mouse exterminator, can emit an ultrasonic wave, so that the brain and optic nerve of mice are impacted, causing disorder, until death. The ultrasonic rodent exterminator of more than 30 kilohertz developed in China has a good effect on rodent control. Cockroach and mouse repellent are combined into one, through multiple emitters simultaneously produce ultra-high frequency wave stimulation, interfering with the nerves, hearing and reproductive systems of rats and cockroaches, so that they can quickly escape.
