An ultrasound dissuading device for animals is composed of an electronic apparatus for emitting ultrasonic waves with a dynamic movement of the emission field, and an operating control system, that operates through internal and control signalling devices for a possible external modem. The device comprises a mobile head (1,29) composed of a sheet container containing a double ultrasound piezoelectric emitter (3,4). Its mobility is obtained with an electronically controlled servomotor (18), placed inside the central body (2,30) of the device, that produces an alternate movement of about 180° along the two directions for every emitter (3,4), allowing a complete coverage of the emission circumference. |
