InterHarmonics has built its name on designing devices that sit somewhere between musical instrument, sound design tool and experimental art object. The Geophon might be their most interesting creation yet. It is a compact, tactile contact microphone built to capture vibrations, resonances and hidden textures you simply can’t hear through air alone.

At first glance it looks like a beautifully made sculptural object, but inside is a purpose built sensing engine that picks up the subtle movements running through wood, metal, stone, drum shells, strings and anything else that transmits physical energy. You place it on a surface and the world around you suddenly opens up. The scratch of a pencil becomes a thunderous rasp, the body of an acoustic guitar becomes a subsonic landscape and everyday materials become new instruments.
What sets the Geophon apart is the clarity and expressiveness of the signal. A lot of contact mics are noisy or one dimensional. This one feels alive. It handles delicate textures, heavy impacts and sustained drones without choking the tone. Paired with pedals, modular rigs or software effects, it becomes a portal into sound design possibilities that usually take multiple pieces of gear to achieve.
InterHarmonics also leans into the creative side of the tool. The physical design encourages hands on exploration. You can press it, slide it, drag it or rest it gently and each method produces a different character. It invites experimentation in the same way a good musical instrument does and rewards anyone who likes discovering new sonic angles.
For musicians, producers and Foley artists, the Geophon fills a niche that has always existed but never felt this refined. It is a contact mic built for texture rather than utility and it gives you access to a layer of sound most people never think to explore. If your work leans toward atmospheric detail, experimental tones or turning the everyday into something musical, this little object is an inspiring place to start.
