Abstract
A voice bulb, which is adapted for detachably mounting to an electric bulb socket, includes a supporting housing, an illumination unit, and an audio unit. The supporting housing includes a supporting base and an electric head extended therefrom for detachably connecting to the bulb socket. The illumination unit is extended from the supporting base for providing an illumination effect. The audio unit includes an audio outlet provided on the supporting base, and an audio circuit disposed in the supporting base to electrically connect to the electric head, wherein the audio circuit is selectively activated to produce a sound effect through the audio outlet to coordinate with the illumination unit so as to provide an audio-visual effect of the voice bulb.
