ABSTRACT:
A greeting card device which enables, by blowing, an LED to be switched off or a sound module (music, voice or noise) to be activated or deactivated, or a combination of a light and a sound to be activated or deactivated simultaneously. The device is composed of a bimetallic strip system, which the user blows on as if blowing out a candle, and which is connected to the integrated circuit of the LED or the sound module or both, as well as to a resistor and a capacitor which, by charging and discharging, allows switching on-switching off cycles to be repeated. The device according to the invention is particularly suited to the animation of greeting cards (birthdays, Christmas, etc.).
