ULTRASONIC GENERATOR FOR REPELLING MOUSE

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic generator, using no sophisticated controlling system, accordingly producible at a low cost, capable of not only threatening a mouse but also preventing habituation (learning) since it can randomly generate various composite waves and enabling the simple on-off controlling by signals of timers and various sensors using plural transducers and the sure repelling of a mouse in a specific region. ;SOLUTION: This apparatus is composed of an ultrasonic-generating part and an electric source part. The ultrasonic-generating part is composed of transducers generating ultrasonics of 17-25kHz at extremely high sound pressures. Plural transducers consisting of identical independent transducers or combinations of different transducers can randomly generate ultrasonics having composite frequencies and sound pressures by means of a controller which changes a dispatching time of each of the plural transducers.;COPYRIGHT: (C)1997,JPO
