Abstract

PURPOSE: To enable stable and excellent reproduction, by the construction that the external shape of the contact section between a fixed section and a viscoelastic body is made smaller than that between an oscillation system and the viscoelastic body, in a cartridge damped through the viscoelastic body between the oscillation system and the fixed section.
CONSTITUTION: Viscoelastic bodies 3', 3" made by butylrubber damp an armature 2 having a cantilever 1 and the armature is fixed to a fixed section with a suspension wire 5. The shape of the damper (viscoelastic body) 3" in contact with the fixed section 4 is made small and the shape of the part 3' in contact with the armature 2 is made large. Thus, the high band resonance is damped with the mass of the damper 3'. On the other hand, since the effect of mass component is less at a low frequency region, the contact area with the fixed section is small for ease of bending, then the mechanical impedance characteristics is made excellent. Accordingly, the stable and excellent reproduction can be made.
