An activating device for light-emitting wheel comprises a wheel, a sound and light generating circuit, a plurality of light emitting elements and a plurality of conductive wires. The wheel has a hub at the center of the wheel, a plurality of spokes radially arranged around the hub and a rim arranged around the outer contour of the plurality of spokes. An interspace chamber is formed between two adjacent spokes. The sound and light generating circuit is arranged within one of the interspace chambers. The sound and light generating circuit has a housing case, two conductive plates, an activating element and a top cover on the housing case. The two conductive plates are of the same structure and have slantingly bent bottom portions. The two conductive plates are such mounted on the housing case that a predetermined separation is kept between the two slantingly bent bottom portions thereof.
