Sony Discman

Discman was a brand name used by Sony for their portable CD players. The first Discman, the Sony D-50 or D-5, was launched in 1984. The Sony brand name for Discman changed to CD Walkman, initially for Japanese lineups launched between October 1997 and March 1998, and then entirely in 2000. Discman and CD Walkman players were discontinued at the beginning of the 2010s, when they lost popularity with the general public. 来源：https://en.wikipedia.org/wiki/Discman 主图来自 Wikimedia/Wikipedia，发布前请核对 Commons 许可。
