APPARATUS OF VISUO-AUDITORY STIMULATION

摘要

An apparatus for visual and auditory stimulation is provided to allow a subject to three-dimensionally recognize the visual and auditory stimulation by variously changing a position of the visual and auditory stimulation. A plurality of guide bars(30) are fixed between a lower support(10) and an upper support(20) at predetermined intervals and connect a lower support and an upper support. A plurality of racks(40) are fixed between the upper support and the upper support at predetermined intervals. A plurality of multistage semicircular panels(50) are lifted along the guide bars and the racks and include a plurality of LEDs(51) and a plurality of speakers. A plurality of DC motors(60) are mounted on rear surfaces of each of the semicircular panels and lift the semicircular panels by rotating pinions engaged with the racks forward and backward. A plurality of potential meters(70) sense and output the rotation number of each of the DC motors. A limit switch(80) is mounted on a top surface or a bottom surface of each of the semicircular panel and senses whether an upper part or a lower part of the semicircular panel is in contact with the lower support, the upper support, or another semicircular panel in a lift of each of the semicircular panels. A controller(90) controls the lifts of the multistage semicircular panels in a manual mode or an automatic mode by controlling forward and backward rotation of the DC motors while checking output of the potential meters and sensing states of the limit switches.
