Realistic 3D render of a portable passive acoustic smartphone amplifier for a school project. The design is compact, modern, and portable like a small JBL speaker. The smartphone is partially visible and accessible from the top, placed at about a 60-degree angle in an open slot so the screen can still be touched easily to change music and control volume. Only the bottom speakers of the phone connect into the acoustic chamber. The amplifier body uses a smooth progressive exponential horn shape expanding into a large oval opening. Total length about 25 cm. Final oval opening about 12 cm wide. The horn has smooth internal curves, no sharp angles, optimized for passive sound amplification. Matte black ABS plastic or smooth wood material. Include visible technical measurement annotations in French: “25 cm” along the body and “12 cm” across the oval opening. Side perspective view on a clean white background, highly detailed industrial design prototype, realistic lighting, ergonomic and functional design. Mehr sehen
