Abstract
PURPOSE:To attain the transmission of in-phase and different phase transmission of a signal by providing plural piezoelectric substances each provided with a couple of electrodes onto a supporting body. CONSTITUTION:The supporting body 4 is made of a material such as an aluminum plate having 1mm thickness, a piezoelectric substance 6 is made of a sintering body of zirconium lead titanate of 0.5mm thickness and piezoelectric units P3, P4 of the same constitution arranged with the electrode 5 arranged on both sides of the piezoelectric substance 6 are bonded to both faces of the supporting body 1. In applying an electric signal to the unit P3 from the electrode pair C-C', the piezoelectric body 6 of the unit P3 is deformed by the inverse piezoelectric effect to deform the supporting body 4. An electric field by the piezoelectric effect is induced in the unit P4 attended with the deformation of the supporting body 4 and a similar output to C-C' appears to the electrode pair D-D'. In making the direction of polarization, that is, the opposite direction of the piezoelectric axis, the phase of the extracted signal is shifted by 180 deg..
