ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to speakers, and more particularly to flat speakers for a personal computer in a multimedia environment.
BACKGROUND OF THE INVENTION
Speakers are typical peripheral devices for a personal computer of modern times. A conventional speaker for computer is made of plastic material having a grille on a front side thereof for amplifying sound to a desired volume. However, such conventional speakers are monotonous in their external appearance due to the design of grille. The only possible design difference between any two speakers is the shape of cabinet. Thus, there is no breakthrough to the design of grille.
It is desirable to provide a new and improved speaker to overcome the above limitation of prior art.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide flat speakers for a personal computer having a diaphragm glued to the front side of cone for amplifying the sound and thus a conventional grille is eliminated. Further, a variety of patterns may be printed or painted on the flat front side to provide a sightly appearance.
It is another object of the present invention to provide flat speakers for a personal computer having a smaller horizontal length as compared with a conventional one, whereby it is possible to put it on table without occupying much space, or alternatively to mount it on the wall because of its lightweight.
It is still another object of the present invention to provide flat speakers for a personal computer including a pair of opposing longitudinal groove members of generally E-shaped section provided on the side edges for placing a photograph or picture therebetween for acting as a photo frame additionally.
It is further object of the present invention to provide flat speakers for a personal computer in which a three-way connector is provided on the back of cabinet for allowing three different securing directions to be implemented between cabinet and the projected stand of speaker base, whereby three different configurations are realized.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
