Abstract

PURPOSE:To suppress the peak or dip of a high range, by securing a parallel and equivalent working for both the viscid resistance and elastic components of a damper. CONSTITUTION:The 1st rubber member 4d formed with a column of rubber having a comparatively high hardness is provided at the center, and the doughnut- shaped 2nd rubber member 4c is provided concentrically around the member 4d. The center hole is shown by 4e. The member 4c is softer than the member 4d. The press-bonding force at the area near the member 4c is not increased so much although the press-bonding force is increased to the armature near the member 4d at the center part where no effect is given to the compliance. As a result, no peak nor dip is produced at a high range even through this cartridge is applied to a damper of a pickup cartridge of high-compliance type.
