At present, NdFeB magnetic circuit has been used in portable radios, tweeter and mobile phones in China, but it is rarely used in subwoofer.
It is mainly due to the price of NdFeB, the reasonable design of magnetic circuit, the overall magnetization method of magnetic circuit, the stability of air gap flux density and so on.
NdFeB has been put into mass production for 18 years, the magnetic properties have been greatly improved, and the price has dropped a lot.
For example, the price of D12.5X1.5 disks used in thin loudspeakers is only 1/5 of what it was more than a decade ago.
The NdFeB patent will expire in 2003, when its export restrictions will be lifted.
The use of NdFeB in the magnetic circuit of subwoofer is beneficial to reduce the volume and weight of the magnetic circuit, and it is easy to make shielded magnetic circuit.
It is especially suitable for use in televisions, multimedia and cars.
The following will discuss the reasonable design of the NdFeB magnetic circuit of the subwoofer, the ways to reduce the cost of the magnetic circuit, the assembly and overall magnetization of the magnetic circuit, and the methods to improve the stability of the air gap flux density of the magnetic circuit.
