ABSTRACT:
Electronic timepiece delivering an acoustic signal to signalize to the user a particular state of working mode. The invention applies more particularly to timepieces with a digital display for indicating the time and the date, the same display being used to indicate the time of alarm. In such a timpiece, it is necessary to be able to make corrections of the time and the date in the watch correcting mode as well as corrections of the time of alarm in the alarm correcting mode. It is this alarm correcting mode which, in the described example, is signalized by an acoustical signal.
The timepiece includes an oscillator, a frequency divider, at least one display unit, an alarm device, a memory and a comparator for the time of alarm, a control logic circuit and a first and a second control means. It includes further an electronic circuit controlled by the control logic circuit delivering a periodic signal of predetermined duration whiich is generated from signals delivered by the frequency divider to activate the electroacoustic transducer of the alarm device when the timepiece has been set in a determined working mode by an action on the control means which are connected to the control logic circuit.
