Abstract

L'invention porte sur une alarme à temporisation comprenant un corps, un crochet, une pile, un commutateur de puissance, une carte de circuit imprimé, un commutateur de déplacement d'angle et un haut-parleur. Une puce principale sur la carte de circuit imprimé est une puce phonétique programmable, alors que le commutateur de déplacement d'angle est relié au terminal d'entrée de la puce phonétique programmable et le haut-parleur est relié au terminal de sortie de la puce phonétique programmable. Le coût de l'alarme à temporisation faisant intervenir une puce phonétique n'est pas plus élevé que celui d'une puce normale, mais l'invention a l'avantage de permettre de temporiser après enclenchement du commutateur de déplacement d'angle et d'éviter une sonnerie fausse. Les coûts sont bas et la structure est rationnelle.
