In a conventional speaker, a voice coil is suspended on a damper made of cloth. As the voice coil moves up and down, the damper also vibrates. This generates secondary sound pressure waves that can cause distortion of sound.

Magnetic fluid technology is used to control the motion of the speaker cone with a dampless suspension. This eliminates the sonic distortion.

Magnetic Fluid vs Traditional speaker

Sony magnetic fluid speakers can also significantly boost energy efficiency by eliminating dampers. The speakers will play louder with less power.
