当时，井深大会长为了出差听音乐携带了TC-D5和大型耳机。 但仅仅为了方便听音乐，TC-D5显得体积太大了， 而且不必要的功能太多，放入电池后重量竟然达到了1.7公斤。 所以当时就希望能有一台配备轻巧耳机的小型化机器。 于是井深大会长让研发团队制作了实验机，这就是 Walkman的原型。
盛田昭夫社长从这台实验机上看到了商机。 然而不能录音也不带扬声器的播放机在当时市场上是没有的， 所以在公司内部对于产品的质疑声也越来越高。 因此盛田昭夫说出了开头的台词，「随身携带音乐」的文化也由此诞生了。
SONY WALKMAN legend
At that time, the President of ibuka university brought tc-d5 and large headphones for a business trip to listen to music. But just for the convenience of listening to music, the tc-d5 is too big and has too many unnecessary functions. It weighs up to 1.7kg when put into the battery. So I wanted a small machine with light headphones. So ibuka asked his team to build a prototype of the Walkman.
Morita saw a business opportunity in the experimental plane. However, players that could not record and had no speakers were not available in the market at the time, so there was growing skepticism about the product within the company. So morita uttered the opening lines, and a culture of “carrying music with you” was born.
“If I can’t sell 30,000 units, I will resign as President.”
第一台 Walkman的最初原型被认为来自单声道的TCM-100,但实际上是装有立体声磁头的BM-12。另外附属的H.AIR耳机是在Zero-Fit设计理念的基础上研发的，定位为佩戴轻巧的开放式耳机，可以说有了这款便携耳机才有了 Walkman的诞生。

1979 SONY tps-l2 Walkman from here to Walkman Walkman
When wearing headphones listening to music in the outdoor culture of SONY hasn’t flow line, because if the ear with a chance hinder conversation with others, also can’t hear the voices around, so the host at the top of the installed a very conspicuous orange “HOTLINE switch. By pressing this button, the microphone will gather around the sound output into the headset, so through headphones can hear the voice of the surrounding.
The original prototype of the first Walkman was thought to have come from the mono channel TCM-100, but was actually a bm-12 with a stereo head. In addition, the attached h.ir headset was developed on the basis of the zero-fit design concept, which is positioned to wear lightweight open headphones. It can be said that this portable headset gave birth to the Walkman.

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.
