BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
illuminated speaker having a design effect by illumination.
[0002]
2. Description of the Related Art In recent years, as speakers of audio equipment mounted on a
rear tray of a vehicle, those which have been decorated by adding illumination (lighting) have
come to be used, and lamps are provided on the back of box speakers. Due to such factors as
illumination, speakers with illumination that display and illuminate characters and the like have
come to appear.
[0003]
However, illumination is generally applied to the back of the box speaker, and illumination to the
speaker unit mounting surface, in particular to the speaker unit itself, is also performed due to
structural difficulties and the like. It was not.
The present invention has been made in consideration of such a point, and an object of the
present invention is to realize a loudspeaker in which a relatively small loudspeaker unit such as
a tweeter or a squawker is illuminated.
