I’d break it down into modules. First, a sensor to detect lift—maybe a small accelerometer in the base. Next, a micro‑controller to interpret that motion and trigger playback. For the poem, a tiny speaker or resonant cavity tuned to the cup’s shape. I’d design the cup’s geometry so that when the lid is lifted, the air inside vibrates at the correct frequency, acting like a built‑in speaker. Then I’d add a battery compartment for power. Finally, I’d test each component separately, then integrate, making sure the cup’s structural integrity isn’t compromised. The key is precise timing and minimal noise interference.
