A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

01 / Overview

The exhibit uses electromechanical devices to transform changes in sound and audio into visible trajectories of light points, providing participants with a novel sound experience.

02 / How visitors use it

Interaction type: Electromechanical, hands-on. The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

The exhibits consist of speaker models, amplifiers, laser emitters, and other components. Install a mirror and laser emitter at the sound outlet of the horn model. During interaction, visitors blows the horn on the table, and the vibration of the sound waves inside the horn causes the mirror to vibrate. At the same time, it drives the laser points on the mirror to reflect onto the wall, and visitors can observe the movement trajectory of the laser points.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
