Talkbox adapter for phone

This full-width sleeve clips snugly over the bottom edge of an iPhone 16 Pro and captures the right speaker's output through a sealed chamber, funneling it straight down through a barbed nipple into standard 3/8" ID vinyl tubing (aquarium or utility tube, available at any hardware store). What you need: ~3–4 ft of 3/8" ID clear vinyl tubing (hardware store, ~$1–2) Optional: thin closed-cell foam tape (3M weatherstrip) applied around the inner rim of the floor for a better acoustic seal against the phone Usage: Slide adapter onto the bottom of your iPhone 16 Pro, right edge flush Press 3/8" vinyl tube firmly onto the barbed nipple Put the free end of the tube near your mouth Play audio from your phone — music, synth app, voice Shape the sound by mouthing vowel sounds without vocalizing
