The invention relates to a post card device which, by means of blowing, can be used to turn off a light emitting diode, activate/deactivate a sound module (music, voice, sound effects) or activate/deactivate light and sound simultaneously. The inventive device comprises a bimetallic system (1) on which the user blows as if to blow out a candle. Said bimetallic system is connected to the integrated circuit of the diode, sound module or both and to a resistor (2) and a capacitor (3) which, by charging and discharging, can be used to repeat the switching off/switching on cycles. According to the invention, the device is particularly suitable for animating double fold over-type post cards (birthday card, greetings card, etc.).
L~invention concerne un dispositif de carte postale permettant en soufflant d~éteindre une diode lumineuse, ou d~activer et désactiver un module sonore (musique, voix, bruitage), ou d~activer et désactiver simultanément la combinaison d~une lumière et d~un son. Le dispositif est constitué par un système "à bilame" (1) sur lequel l~utilisateur souffle comme pour éteindre une bougie, relié au circuit intégré de la diode ou du module sonore ou des deux, ainsi qu~à une résistance (2) et un condensateur (3) qui, en se chargeant et se déchargeant, permet la répétition des cycles extinction - allumage. Le dispositif selon l~invention est particulièrement adapté à l~animation de cartes postales de type carnet double (anniversaire, v.oelig.ux,~)
