Abstract
A stylus for stereo pickups tracking acoustic events mechanically recorded in grooves of a plate shaped record carrier comprises a soft iron tube which is adapted to embody a transducer and which has an open end into which a needle support tube is engaged and secured such as by adhesive connection. The needle is carried by the support with its axis substantially perpendicular to the axis of the support tube at the outward projecting end of the tube. The soft iron tube and the support tube are engaged in an opening of a support plate and embraced by a first elastic element engaged in the opening and elastically engaged with the soft iron tube. The construction includes a second elastic element engaged around a portion of the soft iron tube and the support tube at a location adjacent the open end of the soft iron tube and forms a damping body of a material of high internal friction.
