Abstract
The electronic signaling system comprises a base unit including an audio media player for reproducing a recorded audio signal from an inserted recorded medium, and an audio output stage for producing an audio output responsive to the occurrence of a trigger signal. A remote triggering device, such as a doorbell, includes a signal generator for communicating energy from the triggering device to the base unit. A receiving device in the base unit is provided for intercepting the energy communicated from the triggering device for reproducing the recorded audio signal. The medium may be a replaceable medium, permitting the user to select, from a variety of sound recordings, which recording is to be played back when a visitor or a guest pushes the doorbell. The replaceable medium may be recordable by a user. The audio player is preferably a player capable of reproducing sound patterns from integrated circuits containing encoded or non-encoded sound program information. A simplified electronic signaling system may be placed in a child's room. When a pushbutton outside the child's room is pressed, a preselected sound/audio/song/message/program is played by the base unit in the child's room…
