Watch with time information VIA silent vibration
First Claim
1. An electronic timepiece adapted to deliver time information in silent tactile manner and comprising:
- a housing closed by a glass;
a time-keeping circuit associated with an analog or digital display, notably comprising an oscillator and its maintenance circuit, a division chain and counters;
control elements provided on the outside of said housing, selected from amongst a bezel (L) provided with numerical tactile marks (Ni) or functional marks (Mi) opposite sensors and a crown and buttons with push-button function (C, B1, B2),an interpretation circuit of the displacements of said control elements (L, C, B1, B2),electronic coding means adapted to code time signals received from said time-keeping circuit and/or non-time signals received from said interpretation circuit in the form of pulse strings, anda device generating silent vibrations, wherein, in said timepiece, said control elements (L, C, B1, B2) cooperate via the intermediary of said interpretation circuit with said electronic coding means to drive the vibration generating device by means of pulse trains so as to emit vibration pulses representative of time information or of the accuracy of a time instruction or non-time instruction introduced by means of said control elements.

Abstract
An electronic timepiece having an analog or digital display delivering time information in silent, tactile manner in which the control elements (L, C, B1, B2) provided on the exterior of a closed housing cooperate via the intermediary of an interpretation circuit with the electronic coding means (22) to drive the vibration generating device (23) by means of pulse strings to emit vibration strings representative of an item of time information or of the accuracy of a time instruction or non-time instruction introduced by means of said control elements.
The timepiece presents a conventional appearance, but enables a visually impaired person to know the time, to correct the internal time and to set an alarm time.
