The automatic audio playing device mainly contains a hollow body member, a control unit housed inside the body member, a plug member and a speaker as integral parts of the body member, an adaptor, and a remote controller. The control unit has a radio reception circuit for receiving control signals from the remote controller. The control signal is forwarded to a signal processing circuit, which in turn triggers a microprocessor in accordance with the control signals. The microprocessor instructs an audio playing circuit to play an appropriate digital audio file via the speaker. The plug member could be plugged into a conventional lamp socket for a light bulb, or the plug member is first plugged into the adaptor and the adaptor is then plugged into a conventional wall socket. Once this is done, the automatic audio playing device could be turned on and off by switches of existing wiring.
