Phone Amplifier Passive Speaker Cardboard

The object is a passive amplifier for smartphones with a sleek and functional design. The structure includes an angled housing that holds a cylindrical coil, enhancing sound propagation, although the system also works without it (see plate 2). The top section features a slot for the smartphone, while the grooves on the body are purely aesthetic, giving it a modern and refined appearance. 

PRINTED WITHOUT SUPPORT!

 

In the second profile called "CONO," there is a replica of the cardboard insert, redesigned with an optimized shape to further enhance sound amplification when the volume is increased.

It features technical innovations never seen before in these products, from the space-saving phone holder to the sound-optimized design.
