ABSTRACT:
A floor mat includes a housing for containing a power supply, speech module and speaker. A grid-like switching mechanism is closed upon a person stepping on the mat so as to provide an energizing current flow to the speech module. The speech module includes circuitry for recording and playing back a selected message. A slidable or releasable panel in the housing allows for selectable user access to the speech module. The housing precludes weather deterioration of the elements therein and cooperates with the switching mechanism so as to provide a user-selectable message to a person stepping on the mat. The mat/housing configuration allows alternative switching mechanisms to be used in connection with replaceable speech modules.
