Magnetic Fluid Sound Visualizer

The NO. Ferrofluid Sound Visualizer is a Bluetooth portable speaker that encases magnetic fluid in high borosilicate glass. A 10 W full-range driver produces sound pressure of 86±2 dB while the fluid moves in time with audio frequencies down to 53 Hz. The sphere measures 13 x 13 x 13 cm and weighs 870 g, powered by a DC 12 V 2 A supply.

Desktop Decor for Visual Audio Fans

Buyers who want a decorative piece that reacts to music or ambient sound will appreciate the responsive fluid display and gray finish. It suits desks, bedside tables or gaming setups where a visual element adds atmosphere. Users needing battery operation, waterproofing or multi-room audio should look elsewhere because the unit requires mains power and offers only a single wireless connection.

10 W Driver with 53 Hz Low-Frequency Response

The internal magnetic full-range speaker delivers 10 W output and reaches 53 Hz at the low end, which determines how deeply the ferrofluid can visualise bass content. Frequency response spans 100 Hz to 20 kHz, so the fluid reacts across most of the audible range. This specification decides whether the visualiser meets the buyer's expectations for low-frequency movement.
