This chunk of Bradford pear was going to become a small live edge bowl but instead I decided a turn a live edge passive loudspeaker as a quickie Christmas present. The cone was turned on the lathe. The slot on the top was drilled with forstner bits and chiseled smooth. The whole thing was left intentiallly a little crude because it just seemed that anything you leave all of the bark on should be left a little rough anyway. Finished with 2 coats of spray lacquer.

It sounds surprisingly good for something so simple. It does not really amplify as some people claim. It mostly just directs most of the sound forward so you can hear it better.

looks awesome, i to like the look of pear bowls, but the passive speaker idea is awesome i will definitely try it.
I see that in the back of that piece there is some tiger stripe, this seems to occur often in pear.

The tiger stripe appears to be crotch grain where a branch split off from the main branch. You can see where I cut the branch off on the left side looking from the front. I’ll have to try to keep more of that grain from future logs.

That’s really cool.

These are called acoustic horns and it’s true they do not technically “amplify” as that would require adding power to the signal, but they can make the sound louder through impedance matching. How much louder will depend on the shape, size, and length of the horn. I’ve made several. The bummer is my new phone only has one speaker, front top, so I can’t easily make a horn for it.

Thanks Rick. I made this for an iPhone 7 which now has 2 speakers to play in “stereo”. The right channel points downward and the left channel,plays through the earpiece. I thought about making one of these with 2 horns where the phone lays on its side to pickup from both speakers. Instead, I changed the phone to play in mono and changed the balance to play entirely through the bottom speaker.

I have 2 requests for one of these from friends and family and I am going to experiment with more elaborate and longer channels for the sound by cutting the back off and using a router to make the channel. I also need to research and see if there is a layout that will boost the bass a little.
