ELECTRIC GENERATOR HAVING PIEZOELECTRIC DEVICE

摘要

PURPOSE: An electric generator including a piezoelectric device is provided to reduce the breaking risk of a vibrator by transforming the vibration using a vibrating shaft which is connected with a weight. CONSTITUTION: The edge of a piezo-electric vibrator(200) is fixed to a casing. A weight(301) is located in the casing to be moved along a straight line. A vibrating shaft(302) passes through the central part of the weight and the piezo-electric vibrator. The vibrating shaft is connected with the weight and the piezo-electric vibrator and synchronizes the movement of the weight and the central part of the piezo-electric vibrator.
