Abstract

The utility model relates to a sweep-frequency ultrasonic mouse driving device. The sweep-frequency ultrasonic mouse driving device comprises a 6V direct-current power supply, an audio-frequency oscillating circuit, an ultrasonic signal amplifying circuit and a transduction circuit. The auditory system of the mouse is very advanced, and carries out communication by an ultrasonic mode and can judge the sound source in dark. A test proves that the mouse is very sensitive for 30-40kHz ultrasonic wave, and the characteristic of the mouse is utilized by the ultrasonic mouse driving, mouse prevention or mouse killing. The ultrasonic wave generated by the sweep-frequency ultrasonic mouse driving device can enable the mouse to hear with an ear-piercing and difficult-standing feel, the brain of the mouse is uncomfortable, and then the mouse can not wait to escape from the site, generates symptoms such as inappetence, anorexia and clonic convulsion and the like due to horror, and finally the purpose of driving away the mouse from places for home, production, living and the like is achieved. If the mouse is forced to be in an ultrasonic environment for long time, ultrahigh-frequency wave can stimulate the mouse, and can disturb and damage the nervous system, the hearing system and the physiological system of the mouse, so that the physiology is disordered to achieve the purposes of driving and killing the mouse.
