摘要:
An earring watch comprises an enclosure 4 with a friction clip or pierced-earlobe hook for attachment to the ear. The enclosure contains an energy cell 18, a timekeeping circuit 42-46-48 and an audio transducer 40 for announcing the time in a series of groups of tones, the number of tones in each group equal to a respective digit of the time. The time is announced when the wearer touches one part of the surface of the enclosure twice, another part 6 of the enclosure is electrically connected to the body via the ear, so that the touch completes a circuit between the two parts of the enclosure. Preferably, and to avoid false readouts due to an inadvertent touch, the watch contains circuitry for providing a time readout only if it is touched twice within a predetermined interval.
