Piezoelectric Speaker Principle: The generated ultrasound can stimulate rodents
Piezoelectric speaker Role: Repel rodents
Features: Multi-scan variable frequency ultrasound
Animals such as mice and bats use ultrasound to communicate. The rat’s auditory system is very developed and sensitive to ultrasound. It can determine the source of sound in the dark. Young rats can emit 30-50kHz ultrasound when they are threatened. When the eyes are not opened, the ultrasound and echo can be used to return to the nest (foreign reference: Allin and anks1971: Carden and Hofer 1992). Adult rats can send out a kind of ultrasound to call for help when they are in crisis, and they can also send out during mating. Ultrasound represents happiness, and it can be said that ultrasound is the language of rats. The rat auditory system is at 200Hz-90000Hz (Foreign references: Fay 1988, Warfield 1973, and The Nature of Sound), if a powerful high-power ultrasonic pulse can be used to effectively interfere and stimulate the rat auditory system, Make it intolerable, feel panic and restless, show symptoms such as loss of appetite, escape, and even convulsions, so as to achieve the purpose of expelling the rodents from their range of activities.
Ultrasonic mouse repeller produces 20KHz-35KHz ultrasonic waves, which stimulate the central nervous system of mice, which will make the mouse feel harsh and uncomfortable. It will make you want to escape from the scene immediately to achieve the purpose of repelling rats. Suitable for all rats The place where the damage occurs, especially for power plants, substations, etc., is particularly effective for repelling rats.
The ultrasonic mouse repeller is composed of an ultrasonic generator, a signal amplifier, a power amplifier and a transmitting device. The ultrasonic generator uses an RC oscillator circuit to generate an ultrasonic signal with a frequency of 20KHz-35KHz. The signal amplifier uses a push-pull amplifier circuit to amplify the signal to 100-200 milliwatts, and then amplify the signal to about 3 watts through the power amplifier, and transmit the zigzag ultrasonic wave through the transmitting device.
