摘　　要：A magnetoelectric(ME) laminated composite made of one pair of piezoelectric Pb(Zr,Ti)O3(PZT) fiber layers with multiple push–pull polarization units laminated between high-permeability metglas ribbon layers with a differential configuration was proposed for vibration noise suppression. Unlike conventional metglas/PZT fiber/metglas three-layer ME laminated structures, the differential configuration has the capability to reject vibration-induced noise from the magnetic signal. The experiment results showed that the differential ME laminated composite was with up to 30 times enhancement in signal-to-noise ratio.A magnetoelectric（ME） laminated composite made of one pair of piezoelectric Pb（Zr,Ti）O3（PZT） fiber layers with multiple push–pull polarization units laminated between high-permeability metglas ribbon layers with a differential configuration was proposed for vibration noise suppression.
