Abstract

L'invention concerne une pendule ou montre électronique à sonnerie. Elle comporte un circuit produisant un signal de sonnerie à une fréquence audible prélevée à un étage du circuit diviseur et modulée par un signal de rapport d'impulsions variable dans le temps. Cette disposition permet de reproduire le son d'une cloche diminuant progressivement, ou un effet de trémolo continu. L'invention s'applique notamment aux montres-bracelets.
