Since most smartphone speakers are oriented downward, the audio output tends to be quite faint when playing music. To address this, my speaker enclosure leverages the principles of sound wave propagation by forcibly redirecting the downward‑directed sound waves, ensuring that the audio is concentrated and directed forward more effectively. In practical testing, we found that the device can significantly boost music volume without needing to increase the phone’s playback volume.

The model is designed to accommodate smartphones with a width of up to 85 mm and a thickness of no more than 15 mm—roughly covering most mainstream phones on the market, though foldable phones and feature phones for seniors are not compatible.
