Abstract: A sound-producing golf ball includes an outer shell with a shock-absorbent inner housing having a rechargeable micro-battery positioned therein. A micro-generator coupled to a rotatably mounted shaft is positioned in the housing. A pendulum depending from the shaft is urged downwardly by gravity for rotating the shaft as the golf ball rolls while in play, thus generating electricity for recharging the micro-battery. A sound chip having a memory for storing audible messages is positioned in the housing along with a sound generator for audibilizing the messages when energized. The housing may include a receiver for receiving a signal from a transmitter for selectively energizing operation of the sound chip and sound generator. The housing presents a geodesic configuration and includes a plurality of interconnected tetrahedral structures for absorbing impact forces.
