ABSTRACT:
An electronic display device renders both an audio message and a visual message. The display device includes a housing, including a frame for holding at least a first and second non-overlapping transparency which contains a visual message, a front panel which contains a viewing aperture for receiving the frame, and a back panel member. Each of the front panel and back panel include an array of peripheral al, spaced apertures through which a fastening device, such as a bolt, can be passed for securing together the front panel member to the back panel member, and sandwiching the frame therebetween. The device also includes a first and second light source for illuminating, respectively, the first transparency and the second transparency. A direct analog audio storage chip is provided for playing an audio message having at least a plurality of audio segments. A sensor, such as a pryoelectric IR motion sensor, is provided for sensing the presence of a person in the vicinity of the device. A controller is provided for controlling the operation of the first and second light sources, and the direct analog audio storage chip, to begin playing a multi-segmented audio message, and to begin illuminating, selectively, the plurality of transparencies, in a sequential manner, to provide a message to a viewer. The operation of the controller, light sources, and analog audio chip are performed in response to the sensing, by the sensor, of the presence of a person in the vicinity of the display device.
