Image Number 3 for United States Patent #8126189.

A multi-directional flat speaker device is disclosed. By the directional characteristics of a plurality of flat speakers of the flat speaker device, accompanying with mechanism to actuate each of the plurality of flat speakers independently rotating to its desired direction, a composite sound field is generated as desired accordingly. The design makes the applications of the flat speaker device more suitable to meet the requirement of future utilizations. The mechanism to actuate the plurality of flat speakers can be achieved by controlling one or more of the flat speakers to rotate in a unique manner. The mechanism can control a facing angle of any one of the plurality of flat speakers independently. The mechanism can be designed by mechanical or electrical controlling manner.
