This works great on my Galexy S8, but may need adjusted for other phones. Let me know what you think! It amplifies the sound of the speaker built in the phone. As for the structure of the inside of the print, it is done mostly with round tunnels for sound travel, so that it is self-supported durring. It looks like an old-school boom box with the tall side speakers. Hope you enjoy my first upload.
Overview and Background
Could be a good lesson in acoustics. examine how changing the shape and size of the cones in the speakers effects the audio output.
Lesson Plan and Activity
acoustics. sound travels. currently the inner tunnels are cylinder tubes. How does it change if you use rectangle tubes? round speakers instead of oval?
