Vibration motor with vibration in the direction of z-axis

A vibration motor with vibration in the direction of Z-axis, comprising:

• a mover carrier, made of magnetically conductive material, and further comprising:
• a suspension spring, in the shape of a long piece and arranged on opposite sides of the mover carrier, with one end connected to the mover carrier and the other end connected to a stator part;
• and
• a coil set, arranged on the mover carrier, and having a coil and a magnetic conductive member, the vibration axis of the coil being wound around a central axis, and the magnetic conductive member being located at the center of a range around which the coil being wound;
• and
• the stator part, having two opposite sides connected with suspension elastic pieces to form an air gap between the stator part and the mover carrier, and further comprising:
• a stator part body, box-shaped to accommodate the mover carrier, and made of magnetically conductive material;
• and
• a flexible circuit board, provided on the stator body to electrically connect the coil set to supply a driving voltage;
• wherein, the driving voltage has a driving frequency, causing the coil set to form an oscillating magnetic field in the vibration axis direction, the driving frequency changes the driving voltage to change the intensity of the oscillating magnetic field, thereby controlling and changing the attraction between the coil and the stator part to cause vibration.
