We make all natural acoustic wood amplifiers for cell phones. Which woods would give us the best sound? Has anyone used wood as an amplifier in this type of way that could give us any advise? Any help would be great.

no idea but the best way to know is to try testing different woods with your own design. Good luck

Hedge, Osage Orange, Bois D’arc or whatever you want to call it is commonly used in duck calls because of it’s superior tonal qualities.

How something sounds is strictly subjective. The type of sound you’re looking for will influence the choices. Do you want a distinct sound signature or a neutral sound that passes on the original signal with little coloration?

Guitar amplifiers use a multitude of woods from old growth pine to plywood to hardwoods. A lot of acoustic guitars use Sitka spruce tops, with rosewood, mahogany, or maple backs/sides, among other things. The primary woods used in violins are spruce and maple. Many electric bass guitars favor swamp ash. All are looking for a specific signature sound that satisfies a particular purpose. Highend home audio speakers tend to use MDF, dense ply, sonotube, and materials that more acoustically inert, with as little sound of their own as possible, so they can hear the original recording with as little change to it as possible.

“lepelerin” has the right idea with experimentation. Try several….the size, thickness and bracing of the panels all make a difference too, so experiment with that aspect too.

Stradivarius violins were made from spruce for the top, willow for the internal blocks and linings, and maple for the back, ribs, and neck. Antonio Stradivari got the wood choices correct.

This is outside of my range of expertise but I have to ask. Is a cell phone as the primary sound source ever going to give a best sound? Is this more about just making it louder. I don’t think of the phones my wife has had (all the i phone series) and odds and ends prior ever having a good sound.

Rosewood would be worth trying. It’s a good percussion
tonewood. Paudauk is commonly used in tongue
drum tops and may be cheaper than rosewood.

I would not mess with bracing. Just use something thick enough
to not need it. You’ll save labor and have fewer returns.

Spruce (stringed instrument tops) and padauk (xylophone keys) are both excellent woods with completely different tonal qualities, those are just two examples. Soft woods will be muddier but warmer, hard woods will be clearer but colder. I mention it to emphasize that you will need to experiment a bit. What I can pass along is second hand—there is a guy selling passive amplifiers who says he tried all sorts of woods and settled on a type of pine (I can’t remember which species) because it was a good combination of warmth and sound. So you might try a couple soft woods and a couple hard woods and see which you like better.

Do a Google search on “wood options for musical instrument soundboards”. A while back I found an excellent written article by a supplier of soundboards. It was surprising the number of woods he mentioned. All were softwoods somewhat akin to spruce including cedar, the best being Sitka spruce. Be aware the demand for spruce soundboard wood is such that most of the available Sitka spruce trees of this quality in Alaska have been used up and are becoming rare, meaning very expensive. But there are alternatives! I would think the Russians and Finns would have an ample supply of equivalent Spruce trees. I wonder why they don’t supply the market.

A spruce soundboard acts much like a drum head- it is part of creating the sound, not just amplifying it. The wood on a guitar or violin which corresponds to the megaphone-like nature of the item in question here is the wood of the sides and back. So, rosewood, maple, and so on.

Loren’s suggestion of padouk is right on, because it’s hard and reflective like rosewood, so it will be loud, but also has a “warm” resonance when set to resonating, which is something that will definitely happen with the design depicted.

The cleanest, loudest, and least colored sound for this megaphone or horn (strictly speaking, that’s what it is) would probably be a space-age composite material like they use on the rounded backs of Ovation guitars, but obviously this device is as much about aesthetics as sound.
