The Sony Walkman WM-10 - also known as the Super Walkman - was released in 1983, and was Sony's first 'miniature' size player. Its small size represents a tour-de-force of early 1980s engineering. This walkman is actually smaller than the cassette it plays! So it needs to be slid open to make the compartment large enough to accommodate the cassette.
The Walkman WM-10 uses a single 1.5V AA battery, and is housed in a compartment next to the heads at the top of the player. The decision to use one AA battery was a brave one, and backed up by a more clever technology. The 1.5V was not enough to run the electronic parts of the amplifier and servo, so a step-up DC-DC converter was implemented to boost the voltage to a useful level.
It truly is a marvel of engineering, and it also sounds quite as good as it looks!
