摘要:
The invention relates to a device for subjecting a spatial area to acoustic oscillation in the ultrasound range or the ultrasound near range, provided with a housing (2) comprising a plurality of irradiation surfaces (20) wherein cylindrical cavities are formed as resonator spaces (22). The housing (2) has a cylindrical inner space (24) and is penetrated by a rotationally fixed vertical axis (4) divided into two. The first part (4′) of said rotationally fixed shaft (4) is formed by an outer bearing flange (40) and an inner bearing flange (45) with distancing bolts (44) screwed thereinbetween, and an electrical motor (6) and a reduction gear (7) are arranged between the two bearing flanges. The second part (4″) of the rotationally fixed shaft (4) is formed by a pot-shaped sleeve (48) to which a collector ring (61) is fixed, a current collector (62) lying on the collector ring (61) in a sliding manner and being connected to the rotating housing (2). Lines lead from the current collector (62) through a borehole (28) into the resonator space (22). This solution enables an effective acoustic irradiation of areas to be protected.
