A hoop type toy is provided having a sound generating system for generating a tone, a steady simple beat, a rhythmic beat, or a tune. In certain embodiments, sound generation only occurs when the hoop is in motion. In other embodiments, the rate, pitch, speed, and/or loudness of the tone, beat or tune varies with the rate of rotation of the hoop. In the preferred embodiments, the sound generating system includes a speaker and a circuit board having an IC chip and integral motion detector. In this way, ruggedness, low cost, and small size are achieved.
