A magnetic momentum transfer generator utilizes three or more magnets aligned with each other. A first control magnet is positioned outside a coil. A second magnet is positioned within the windings of the coil and a third magnet is positioned on the opposite side of the coil opposite the control magnet. When the control magnet rotated or moved, mutual magnetic flux lines generated by all three magnets and passing through the coil winding are aligned at right angles to the coil, thereby inducing a maximum voltage at the terminals. This generator is particularly useful for short burst radio micro-transmitters that can be used for battery-less and wireless switching applications.

A vibration motor with vibration in the direction of Z-axis is provided, including a mover carrier and a stator part; wherein, the mover carrier includes a suspension spring and a coil set, the stator part includes a stator part body and a flexible printed circuit board. The suspension spring is arranged on two opposite sides of the mover carrier, with one end connected to the mover carrier and the other end to the stator part. The coil set includes a coil, wound around the vibration axis, and a magnetically conductive member located at the center of the coil. The two opposite sides of the stator part are connected to suspension spring to form an air gap between the stator part and the mover carrier. The stator part body accommodates the mover carrier. The flexible printed circuit board is arranged on the stator body and electrically connected to the coil set.
