ABSTRACT:
A light emitting golf ball is provided that includes a spherical housing, a fixing container, a light emitting device, a first fitting portion, and a second fitting portion. The light emitting device is disposed in the fixing container and includes an acoustic wave sensor, a controller, one or more light emitting elements and an electricity supplier. When the acoustic wave sensor receives an external acoustic wave signal higher than a predetermined value, it sends out an activating signal to the controller so that at least one light emitting element emits light. This invention is irrelevant to the hitting direction. It has an extremely low defective rate. Furthermore, the product life can be prolonged.
