Piezoelectric vibrator with double-ended shaft support

Abstract

An electronic device may be provided with a vibrator. The vibrator may vibrate to alert a user to an incoming cellular telephone call or other events. The vibrator may have a piezoelectric vibrator motor. The piezoelectric vibrator motor may rotate a shaft about a rotational axis. A weight may be attached to the shaft so that the vibrator vibrates when the shaft is rotated. The shaft may have opposing first and second ends. To help prevent damage to the vibrator during a drop event, the first and second ends of the shaft may be supported by support structures and end caps or other structures for retarding axial movement may be provided. The support structures may be formed from a bracket having vertical members with holes that respectively receive the first and second ends. The stop structures may prevent movement of the shaft along its rotational axis.
