Dynamic type pickup |
摘要 |
A record pickup is comprised of a magnetic yoke with parallel first and second leg portions. The first leg portion supports a coil. The second leg portion has a bore which resiliently supports a conductive bar opposite the coil. The conductive bar is attached to a stylus. Thus, movement of the stylus in a record groove produces a corresponding current in the coil.
