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.
1981 SONY wm-3 and wm-3ex added Walkman support for metal tape to T s-l2
In order to continue the popularity of the original Walkman, it only changed the color in the appearance and added the support of four metal belts, which was named “luxury Walkman”. Meanwhile, it also launched the “excellent Walkman”, which was packaged in a red luxury gift box.
1982 SONY wm-7 was the first Walkman equipped with automatic rollover
The first model is equipped with an automatic flip and a remote control, which only has three functions: play, stop and change direction. The buttons are controlled by logical mechanical electronic control, and equipped with dolby noise reduction B.
1982 SONY wm-r2 built-in stereo condenser microphone Walkman
Is the “recording Walkman” series, the body with high sensitive stereo capacitance microphone, only carry the host can carry on the stereo field recording, recording process can be real-time monitoring through headphones, equipped with electronic control keys and anti-roll mechanism.
1982 SONY wm-f2 with FM radio recording model Walkman
The Walkman, with radio and recording functions, eliminates the capacitive microphone and adds the FM FM function. The recording supports line input and external microphone. The Walkman is equipped with a tape counter for convenient recording and timing.
1982 SONY wm-dd USES a direct drive system to reduce the shaking rate of Walkman
It continues the style of wm-2 and further improves the performance and sound quality. The colors of the fuselage have been increased from 3 kinds of wm-2 to 6 kinds, making it the first model to explore the colorful route. DD(disc direct drive system) is used to drive the flywheel directly through the motor, which is the same drive type as the professional carry-on tc-d5. The active wheel servo system is equipped with a shaking rate of only 0.08%, and is not susceptible to external vibration, which is very suitable for outdoor use of the Walkman
In 1982, SONY wm-d6 was the first professional Walkman
Named “Professional” series Walkman, in the Walkman has the performance comparable to card landline, with quartz lock servo system of DD, the operation of the shaking rate is only 0.04%(at that time, the Professional card landline shaking rate is generally 0.05%). S&F alloy magnetic head, with high saturation magnetic beam density and excellent high-frequency characteristics, supports the recording of four kinds of metal bands, and is equipped with dolby noise reduction B function for the first time.
1983 SONY wm-f5 can be brought to the seaside and snow mountain Walkman
The first waterproof Walkman, this sporty Walkman also USES DD servo system with active wheel drive on the BE, which is based on the idea of stable listening during exercise.

1983 SONY wm-20’s innovative opening method realized the size of the cassette cassette Walkman
To achieve the ideal size of the same size as the tape cartridge, the door is opened by sliding into the tape and the battery, the thickness between the body and the tape is only 6 mm. In order to achieve miniaturization, only one battery no.5 is installed, which means a new circuit is designed to be driven by a voltage of only 1.5V. 5 mm super flat motor, with headphone jack switch (plug in the headphone to energize) function.
