ABSTRACT:
An alarm clock system including an alarm clock circuit having an alarm output signal; a radio transmitter circuit responsive to the alarm output signal of the alarm clock circuit in a manner to transmit a transmitted alarm signal; and an ear insert including an audible output transducer positioned within an ear insert housing, a radio receiving and alarm generating circuit tuned to receive the transmitted alarm signal and in electrical connection with the audible output transducer, the radio receiving and alarm generating circuit generating a signal to the audible output transducer in response to receipt of the transmitted alarm signal. In one preferred embodiment the radio transmitter is electrically coupled to the alarm clock circuit. In another preferred embodiment the radio transmitter circuit includes an audio pick-up, the alarm clock circuit includes a speaker, and the radio transmitter circuit is coupled to the alarm clock circuit through the speaker and the audio pick-up. When audio coupling is used, it is preferred to provide a mechanism for muting the output of the alarm circuit speaker.
