Title
(EN) VIBRATION MOTOR
Abstract
(EN)

A vibration motor, including a shell defining a cavity therein, an axis disposed entirely within the cavity, a first magnet which is rotationally movable relative to the shell and which includes at least two sections having alternating poles, and a second magnet including at least two sections having alternating poles. A first extension tab is attached to the first magnet and extends out of the shell via a slot. An unbalanced rotor is disposed between the first and the second magnets and is rotatable relative to the axis. The first extension tab is movable within the slot, such that moving the tab causes movement of the first magnet and changes a rotational position of the first magnet relative to the second magnet, thereby to change the efficiency of operation of the motor.
