Beryllium was also used for cantilevers in high performance phonograph cartridge styli, where its extreme stiffness and low density allowed for tracking weights to be reduced to 1 gram, yet still track high frequency passages with minimal distortion.
Beryllium blev også brugt til cantilever i high performance fonograf-spidser, hvor dets ekstreme stivhed og lave densitet tillod sporingsvægte, der kunne reduceres til 1 gram, men stadig spore højfrekvenspassager med minimal forvrængning.
