Further, aforesaid piezo-ceramic vibrators, wherein: the electrode of upside of upper piezoelectric ceramic piece is connected by wire with the electrode of the downside of lower piezoelectric potsherd.
Further, aforesaid piezo-ceramic vibrators, wherein: the middle part at the arranged on left and right sides edge of upper piezoelectric ceramic piece is all respectively provided with jagged, the middle part at the arranged on left and right sides edge of lower piezoelectric potsherd is the most all respectively provided with jagged, and on upper and lower piezoelectric ceramic piece, the breach of respective side is corresponding mutually up and down.
Further, aforesaid piezo-ceramic vibrators, wherein: be provided with, on the edge, at least side in sheet metal left and right dual side-edge edge, the gap that wire can be allowed to pass, and gap is positioned in the breach on piezoelectric ceramic piece edge.
Further, aforesaid piezo-ceramic vibrators, wherein: upper and lower piezoelectric ceramic piece is polycrystalline piezoelectric ceramic piece.
The invention have the advantage that piezo-ceramic vibrators the most of the present invention structurally have employed the stacking composite structure that vibration sense is more intensive, and the thickness of vibrator and volume smaller, thickness can be less than 1.5mm；Secondly as piezo-ceramic vibrators can be installed in equipment vacantly by the installing hole at middle part, so make it can produce wing vibration after powered up, make vibration sense be greatly enhanced, and without the interference of EMI, particularly antenna is not affected；Finally, the vibration source of piezo-ceramic vibrators is the piezoelectric ceramic piece that energy consumption is less, so energy consumption also significantly reduces.
