Use the provided white-background product image as the locked product reference. Keep the black Sanag portable speaker unchanged: rounded square body, black mesh grille, orange Sanag logo, top buttons, side button panel, orange braided wrist strap, small strap fittings, proportions, and angle.
Create a vertical rugged outdoor speaker poster in a warm desert-rock style. Place the speaker on a dark volcanic rock ledge with golden sand dunes, fine sand texture, and a soft beige sky. Change the rock platform, sand ripple pattern, dune silhouettes, and foreground pebbles from the original.
Lighting: strong warm sunlight, crisp shadows, rugged premium outdoor electronics mood.
Constraints: preserve product logo and details; no extra poster text, no watermark, no border.
Avoid: copied rocks, copied sand ripples, missing strap, distorted grille, changed logo, people, hands.
