Further, aforesaid piezo-ceramic vibrators, wherein: the upper electrode of upside of piezoelectric ceramic piece and the electrode of the downside of lower piezoelectric potsherd are connected by wire.
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 arranged with breach, the middle part at the arranged on left and right sides edge of lower piezoelectric potsherd is also all respectively arranged with breach, and on upper and lower piezoelectric ceramic piece, the breach of respective side is mutually corresponding up and down.
Further, aforesaid piezo-ceramic vibrators, wherein: at least one side edge in sheet metal left and right dual side-edge edge is provided with the gap that wire can be allowed to pass, and gap is arranged 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.
Advantage of the present invention is: piezo-ceramic vibrators first of the present invention structurally have employed the stronger stacked composite structure of vibration sense, and the thickness of vibrator and volume are all smaller, and thickness can be less than 1.5mm; Secondly, because the installing hole of piezo-ceramic vibrators by middle part is installed in equipment vacantly, make it can produce wing vibration after powered up like this, vibration sense is strengthened greatly, 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.
