摘要:
The present invention is a method and apparatus for conveying audiovisual information. The invention utilizes a speaker as a visual medium. A sheet of material is secured to the radiating face of a speaker. A visual image is then displayed on the sheet of material. Different techniques can be utilized to display the visual image on the sheet of material. For example, a video image can be projected on to the sheet of material or the sheet of material can contain a fixed image. While the visual image is being displayed on the radiating face of the speaker, audible information is being broadcast over the speaker.
