Abstract
The invention relates to an electronic timepiece provided with an electroacoustic transducer for transmitting acoustic signals to indicate a time of alarm, and also for receiving information in the form of acoustic signals to control different functions of the timepiece. Coded acoustic information is delivered to the transducer, for example, by a special apparatus intended for that purpose, and serve to control different functions of the timepiece through a watch and transducer control logic network. The logic network is interconnected with the frequency divider chain, a display control circuit, and a transducer. The logic network includes a selector which connects the transducer either to the output of an alarm logic circuit for delivering alarm signals to the transducer at the time of alarm, or to a transducer detector for transmitting the electrical signals delivered by the transducer acting as a microphone to a watch logic circuit. The watch logic circuit, in turn, controls the alarm logic circuit, the frequency divider chain, and the display control circuit of the timepiece.
