Abstract:
A moving coil type pick up capsule having a body, cantilever having first and second ends, a stylus located at its first end and a coil located at its second end and, therebetween, a dampener having an opening therethrough. The cantilever passes through the dampener opening such that the stylus is on a first side of the dampener and the coil is on a second side of the dampener. First and second magnets or yokes are positioned within or proximate the capsule body and spaced from one another to create a gap, the dampener and coil being positioned within the gap such that the fulcrum is located between the stylus and coil and specifically at the dampener. A dampening fluid fills the gap to complete the assembly.
