The Lantone Speaker

Lantone started as a simple idea: I really liked the Sony LSPX-S1, and I wanted to build my own version from scratch.

I initially tried to approach it "properly" — taking courses, learning how to calculate speaker parameters — but quickly realized that without the right measurement equipment (and access to a wide range of drivers), it wasn't going to be a textbook design. So instead of forcing it, I leaned into a more hands-on approach: using what I had, iterating, listening, and adjusting.

The cylindrical plexiglass enclosure came from the intuition that it would help guide and contain the sound. After a few iterations (and, to be honest, also considering how to efficiently cut a 2-meter tube), I settled on a proportion that sounded and looked right. The rest of the structure was built using 3D printing, forming a compact body that integrates all components into a single piece.

Electronics-wise, the goal was a fully portable system with long battery life. I built a 3-cell Li-ion pack (11.1V), combined with a charging circuit, BMS, Bluetooth module, and amplifier — all packaged cleanly inside the enclosure. One small detail I particularly liked was using a thin 2mm fiber line to guide the Bluetooth status LED to the front panel — subtle, but it adds a nice touch.

The base was printed using wood-like filament, then sanded matte and finished with varnish to achieve a more natural feel.

In the end, it became exactly what I wanted: a functional speaker with its own character — part experiment, part product. A lantern-like object that produces sound… Lantern + Tone — Lantone.
