Device for controlling the functions of an electronic watch

摘要

The case 1 of the watch comprises elements consisting of ribbed zones 3, 4 and 5 of different structures which can supply mechanical vibrations when they are rubbed by the user of the watch. A transducer transforms these acoustic vibrations into an electric signal. An electronic circuit comprising generator means, a pulse shaper, counters, a register and a comparator allows the vibration message generated by the activation of one or the other of the ribbed zones 3, 4 and 5 to be decoded and one or the other of the functions appearing on the display 2 of the watch to be controlled.
