Specific embodiment
Embodiment one:
In embodiment one shown in Fig. 1, which includes servo motor 2, the servo motor 2
Shaft is equipped with the eccentric block 3 that center of gravity is in shaft side；The servo motor 2 is clamped in the card slot 4 of handset shell 1, and
And the electrostriction being made of electrostriction material is lined between at least one side wall of servo motor 2 and the cell wall 41 of card slot
Layer 5 and one layer of rubber sheet gasket 6；The electrostrictive layer 5 it is electric after generate deformation in a thickness direction.
The electrostrictive layer 5 can be made of multiple piezoelectric ceramic piece series stacks, to form biggish deformation limit；
And deformation quantity and input voltage are linearly related, its deformation quantity can be continuously adjusted according to instruction；Can make as a result, servo motor 2 with
Clamping stress between handset shell 1 is continuously adjusted.
