Foldman

Foldman turns a folding phone into a cassette player.

Folded, it's a portable player in your hand. Unfold it and it lays down into a deck.

Play your own music files, or drive YT Music and Apple Music from real piano keys.

The tape moves the way the keys say

Every key is a latching mechanism, and the cassette behind the window follows it, frame by frame.

The keys click (the sounds are synthesised, not samples) and buzz under your thumb. The tape counter is geared to the take-up reel, the VU needles follow the real audio on local files, and the tape packs on the reels show how far through the song you are.

Folded, unfolded, half-open

Foldman reads the hinge and rebuilds itself for each posture, without stopping the music.

Cover screen: the upright player cycling through play, fast-forward, stop, pause and rewind

Folded

An upright portable in blue enamel, edge to edge. The tape stands on end behind a small window; keys, volume and phones socket run down the silver side strip. Unfolded: library panel, the deck with VU meters, counter and keys, and the now-playing panel

Unfolded

The player lies down as a deck: twin VU meters, a mechanical counter, CLICK and HAPTIC switches. Your library is above it, and the cover, up next and liner notes are below.

Half-open on a table: the deck on the top half and the library on the bottom half

Half-open (Flex mode)

Stand it on a table: the deck takes the top half, the library the bottom. Unfolded in landscape on a real Galaxy Z Fold
