Dynamic moving-coil pick-up system for scanning analog gramophone records has a rod-shaped needle-carrier in a casing with its free end fitted with a scanning needle

摘要

Induction coils (IC) (8,9) are arranged one behind the other on a needle-carrier (NC) in the NC's axial direction of reach. Each IC fits in a field range of permanent magnets (13-16, 18-20) that fasten crosswise to each other and, at their point of intersection, form a free space between themselves to hold the NC to allow movement and to hold the IC assigned to a magnetic cross structure.
