We remember the days when a speaker that produced the best sound was big and bulky. Ceramic magnets were the magnets of choice and they had to be large enough to produce the magnetic field required for better sound.
Today, high quality and great sounding speakers are using neodymium magnets. This allows the entire speaker assembly (magnets, voice coil, steel and speaker cone) to be smaller due to the large increase in magnetic field produced by neodymium magnets instead of ceramic.
The rise in wireless speakers and the desire for better quality sound has created the growth we see in the speaker industry as well as the need for the appropriate magnetics expertise to be able to accommodate the changing technology. The neodymium magnets and magnetic assemblies are critical components in these speakers, and we understand the design parameters to press for smaller designs that produce high quality sound.
