Unbalanced spinning wheel vibrates spring steel reeds.
3A60.50 • B+50+45
Steel Reed Resonator. Motorized 'Spinner' to spin the metal wheel. A heavy, metal,slightly unbalanced wheel (gyro) in the Resonator Assembly is set to spinning. As the wheel slows down, each spring steel reed will start to vibrate when the wheel hits the resonant frequency of the reed. The smallest reed vibrates when the wheel is at high speeds. The longest reed vibrates when the wheel has slowed down considerably.
