Abstract
A sound producing system of tumbling bells, characterized in that the vibrations emitted by a rod when struck by a floating element that triggers a "relay" each time a circuit is closed, are captured by a mechanical-electrical translator, arranged suitably, to create a voltage difference of the resonance frequency of such a rod in terminals, which, coupled to an amplifier system, diffuses the sound by means of loudspeakers.
