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.

Claims

1. An acoustic wave induced light emitting golf ball comprising:

a spherical housing having an internal space;

a fixing container having an inner surface and an outer surface, said fixing container being disposed in said internal space and being light transmittable;

a light emitting device disposed in said fixing container, said light emitting device including an acoustic wave sensor, a controller, at least one light emitting element, and an electricity supplier;

when said acoustic wave sensor receiving an external acoustic wave signal higher than a predetermined value, said acoustic wave sensor sending out an activating signal to said controller so that at least one light emitting element emits light;

a first fitting portion disposed between said light emitting device and the inner surface of said fixing container, said first fitting portion being hardening at a room temperature and being light transmittable;

a second fitting portion disposed between said spherical housing and the outer surface of said fixing container, said second fitting portion being hardening at a relative high temperature and being light transmittable.

2. The acoustic wave induced light emitting golf ball as claimed in claim 1, wherein said acoustic wave sensor is a piezoelectric ceramic element including a copper plate and a piezoelectric ceramic plate;

and said predetermined value is approximately 121.0 kHz.
