Magnetic Fluids Deliver Better Speaker Sound Quality
A real-world story of NASA technology finding a life beyond the mission.
About this technology
Overview
In the 1960s, Glenn Research Center developed a magnetized fluid to draw rocket fuel into spacecraft engines while in space. Sony has incorporated the technology into its line of slim speakers by using the fluid as a liquid stand-in for the speaker_s dampers, which prevent the speaker from blowing out while adding stability. The fluid helps to deliver more volume and hi-fidelity sound while reducing distortion.
