Sound reproduction apparatus |
摘要 |
<p>Sound reproduction apparatus comprises a turntable 1 having a surface 4 for supporting a disk record 10 has at least a region 18 of the surface 4 made from a material which has a plurality of voids and an acoustic impedance which is matched to that of the record 10. Such a support surface material provides advantageous dampening properties. The material of the region 18 may be a foamed material such as foamed PVC, may be less rigid than the remainder of turntable 1, and may have a thickness of between 2 and 6 mm. The entire turntable (fig 2, 1) may be made from such a foamed material, having a plurality of voids.</p> |
