摘要： A string vibration sustaining device according to the present embodiment includes a rear pickup converting string vibration into an electrical signal, an amplifier amplifying the converted electrical signal, and an ultrathin electromagnetic driver converting the amplified electrical signal into a magnetic signal to excite strings. The ultrathin electromagnetic driver includes two magnetic pole plates formed of a magnetic material, a rare earth magnet arranged in parallel with the strings between the two magnetic pole plates, and a coil wound in a direction perpendicular to the strings around the rare earth magnet, is formed to be ultrathin to have an entire thickness equal to or smaller than 3 mm, and is arranged in a slight gap between a neck end portion and a front pickup of the electric guitar.
