The inwall of the protection shell be inclined-plane, the incline direction on the inclined-plane from the inwall center for protecting shell to
The both ends of the protection shell are gradually respectively provided with one to the centroclinal of the protection shell, the inwall both ends of the protection shell
The stopper slot that the periphery of circle and the vibrating reed matches.
Further say, be provided with the equally distributed dag of dry plate, the dag between piece if the vibrating reed and ceramics shake
It is circumferentially disposed along the inwall of the protection shell.
Further say, the width of the stopper slot is more than the thickness of the vibrating reed.
Further say, the dag is shaped as fan-shaped, rectangle or ellipse.
Further say, ceramics described in two panels, which shake, is provided with anti-vibration plate between piece.
Further say, the shake circle of outer Monday of piece of the ceramics is provided with insulating barrier, and the insulating barrier is located at the ceramics
Shake between piece and the fixed card slot.
The beneficial effects of the utility model are：
Ceramics of the present utility model, which shake, is provided with an at least spring between piece and vibrating reed, one end of spring and ceramics shake piece
Center connection, the center of the other end of spring and vibrating reed connects, and the inwall for protecting shell is inclined-plane, the incline direction on inclined-plane
To the both ends of protection shell gradually to the centroclinal of protection shell, the air of same volume exists at the inwall center of self-shield shell
When being vibrated in actuator, vibrating reed is set to produce bigger displacement, ceramics, which shake, is provided with anti-vibration plate between piece, can prevent two panels ceramics from shaking
The mutually caused vibration cancellation of piece, larger vibration output can be obtained under equal power consumption, to improve product conversion efficiency,
Body vibration effect greatly increases, steady quality, service life length.
