发明名称 DRIVE CONTROL CIRCUIT FOR LINEAR VIBRATION MOTOR AND METHOD
摘要 A drive signal generating unit generates a drive signal used to alternately deliver a positive current and a negative current to a coil. A driver unit generates the drive current in response to the drive signal generated by the drive signal generating unit and supplies the drive current to the coil. After the drive termination of a linear vibration motor, the drive signal generating unit generates a drive signal whose phase is opposite to the phase of the drive signal generated during the motor running. The driver unit quickens the stop of the linear vibration motor by supplying to the coil the drive current of opposite phase according to the drive signal of opposite phase.
