A premium original magnetic-levitation desktop speaker floats three centimeters above a dark honed-basalt charging base. The compact champagne-aluminum disc has a fine micro-perforated grille and a restrained warm amber indicator ring, with no brand. Place it on a low charcoal plinth against a minimal acoustic-fabric backdrop embossed with broad circular ripple textures. Compose a square advertising hero image from a three-quarter angle, centered slightly high with controlled negative space, coherent shadow and reflection. Sculpt the bead-blasted metal and natural stone using one cool rim light and a warm glow from below. Calm high-end product photography, physically plausible levitation gap, no readable text, no logos, no trademark-like controls, no cables, no holograms, no exploded parts, no watermark.
