FIAMM horn recycle iPhone passive speaker

Weekend craft project with my daughter.

I had stock FIAMM horn and some freeway Blaster that are just sitting and collecting dust in garage.. So turn into Passive front load horn for iPhone.


Cut "snail shell" portion, it kinda has exponential horn like structure.

Super simple, just pop in box and layout sound duct into input holes.



Hi and Lo,, it really not much benefit using "Dual Tone" setting.. iPhone speaker just isn't outputting much bass to begin with anyway from such tiny speaker.

So it's just for "looks"







As simple as it looks, no detailed design.




It amplify sound pretty good. Can't say it's well balanced though... mostly mid range enhanced sound. Some lower and overall resonance added, but not enough to feel bass.

It was fun easy project. Kinda want to experiment more design to see how much I can boost bass out from tiny iPhone speaker.

Anyone make those passive speaker?

Pretty cool project. How much would you say it amplifies the sound?

There is clearly audible difference in terms of volume.
Haven't measure dB difference. No scientific detailed analyze tested.

Well, it felt louder than when iPhone in Mug Cup with much warmer and softer sound than mug cup.

It probably can improve better with proper designing I believe.
