现在说起 Walkman很多人都会想起这台名机中的名机，它的方案设计比TPS-L2还要早一年，当时是以索尼设计室在参加设计比赛中提交的一台概念机为原型开发的。这台概念机原本是作为便携采访用的机型，因此设计了紧凑的电路和超薄型马达从而实现了小型化，同时在材料技术方面也实现了轻量化。之后工程师们以此概念机为基础进行了WM-2的开发，小型化的尺寸和独特的按钮布局保持了原样。本机型在1981年2月发售，销量超过250万台以上，创造了单一机型销售的最高纪录。

1981 SONY wm-2 decided the development direction of Walkman Walkman
The Walkman, which many now think of as the name of the machine, was designed a year earlier than the tps-l2, based on a concept submitted by SONY in a design competition. Originally intended as a portable interview machine, the concept machine was designed with compact circuits and ultra-thin motors to achieve miniaturization, as well as lightweight materials and technologies. Engineers then developed the wm-2 based on the concept, keeping the miniaturized size and unique button layout intact. It was launched in February 1981 and sold more than 2.5 million units, a record for a single model.
