Abstract

A acoustic card having a permanent magnet and a reed switch is provided. The acoustic card includes a first flap, a second flap, and a sound generator attached to second flap. The acoustic card divided by a fold into two halves, such as the first flap and the second flap, is unfolded in an opened position and folded in a closed position. The sound generator attached to the second flap includes a printed circuit board, a sound card containing a controller and a memory storing audio sound data, and a reed switch. A permanent magnet attached to the first flap does not directly contact the reed switch attached to the second flap. The permanent magnet moves away from the reed switch to be closed to activate the sound generator to produce audio sound and moves close to the reed switch to be opened to deactivate the sound generator to stop producing the audio sound.
