1. A vibration motor, comprising:
a base having an accommodating space;
an electromagnetic drive unit, located in the accommodating space and fixed to the base, and configured to provide an electromagnetic drive; and
a vibration unit, comprising a magnet-conducting plate and an elastic assembly supporting the magnet-conducting plate on the base and suspended above the electromagnetic drive unit, wherein the magnet-conducting plate and the elastic assembly are both spaced apart from the electromagnetic drive unit, and the magnet-conducting plate is located within an electromagnetic field range of the electromagnetic drive unit;
wherein the vibration motor further comprises a vibration feedback control unit comprising:
a flexible circuit board, comprising a circuit board main body fixed to a bottom of the base, a first circuit board extension formed by bending the circuit board main body to extend into the accommodating space, and a second circuit board extension formed by horizontally extended from the first circuit board extension in a direction away from the electromagnetic drive unit; wherein the first circuit board extension and the second circuit board extension are both spaced apart from the electromagnetic drive unit, the vibration unit and the vibration unit;
a pressure-sensitive block, wherein the pressure-sensitive block is made of polymer conductive material, and is spaced below the vibration unit; the pressure-sensitive block is fixedly stacked on the circuit board main body to form an electrical connection; and the second circuit board extension is attached to a top of the pressure-sensitive block to form a fixed electrical connection; and
an elastic support member, wherein one end of the elastic support member is fixed to a top of the second circuit board extension, and the other end of the elastic support member is fixed to the vibration unit for transmitting a vibration from the vibration unit to the pressure-sensitive block.
